094: Fast Radio Bursts, Nobel Laureate inserts foot in mouth, and more...
<h2>On This Week’s Show</h2> <ul> <li>First use of Bluetooth discovered</li> <li>Some new fast radio bursts discovered</li> <li>Another case of foot in mouth</li> <li>News of a proper space rocket</li> </ul> <hr class="wp-block-separator" /> <h2>Science News with Chris MacAlister, and Nevena Hristozova</h2> <h3>Blue tooth reveals unknown female artist from medieval times</h3> <h4>Chris MacAlister</h4> This story has, like the light from Rigel, travelled to us over the centuries to provide a small but noticeable illumination to our modern world. Our story starts with a team of intrepid scientists making an heroic survey of ancient tooth plaque. A movie premise that is bound to get you popcorn munching and creating some tooth plaque all of your very own. Studies of this tartar can provide us with a many clues as to the otherwise forgotten lives of people who WILL be direct ancestors of many of us. This dental bacterial film has been found to contain DNA, living bacteria, textiles, pollen, food and even tiny insect wings; which I’m really hoping don’t qualify under the heading of food. Although, this was a time where the drinking water was reputed for its tendency to contain “creeping things”! Like any great story, this team made a discovery that was not expected. Blue tooth; well blueish tooth; well teeth with bits of blue on them to be precise. Blue in the form of lapis lazuli, a name that is embarrassingly sexy considering that it literally translates into english as Blue Stone! And that’s exactly what it is. But lapis lazuli is so important because blue is a rare pigment to come by, so this rock was THE blue pigment and was therefore highly valuable. The most likely explanation for the blue spangled teeth was that they belonged to an artist. Books from these days were all handwritten and were commonly decorated with beautiful and intricate illustrations. An artist moistening the tip of their brush with saliva may well have deposited pigment on their teeth. This theory is bolstered by the discovery being made on the grounds of a religious site, as monks were the people who performed most of this work. But the big surprise was that this person was not a monk. SHE couldn’t have been. She was a nun. This may not seem like a big deal today, but the jobs that women were allowed to do all of those years ago were very restrictive and working on intellectual materials like books was not previously considered to be within the remit. It may be that tartar, of all things, is helping us to rewrite history!] <a href= "https://www.sciencenews.org/article/dental-tartar-identify-woman-medieval-book-painter"> Science News</a>, <a href= "https://www.nytimes.com/2019/01/09/science/10-archaeology-teeth-painting.html">New York Times</a> <hr class="wp-block-separator" /> <h3>Thirteen New Fast Radio Bursts Discovered</h3> <h4>Nevena Hristozova</h4> It’s finally happening – they are speaking to us! If aliens were to radio-signal us they’ve found probably the friendliest nation to contact! Enough of stereotypes – Canadian scientists have detected fast radio bursts from a galaxy 1.5 billion light years away. Thirteen of them! Coincidence? I don’t think so! This is only the second time an observation like this has been made, and the first one was done by a different telescope. Scientists have no clue what this might be, but just to calm the spirits down – one of the most notable other times when astronomers detected frequent radio bursts in a pattern – we also thought it was aliens, and it turned out to be pulsars. Which if you ask me is even cooler! <a href= "https://www.bbc.com/news/science-environment-46811618">BBC Science and Environment</a>, <a href= "https://www.sciencenews.org/article/second-repeating-fast-radio-burst-tracked-distant-galaxy">Science News</a> <h3>Lab Boots James Watson, Citing ‘Unsubstantiated and Reckless’ Remarks</h3> <h4>Chris MacAlister</h4> It’s often said that you should never meet your heroes for fear of being disappointed. But sometimes people save you the trouble and broadcast their cockwombledry for the world to see. Enter James Watson; the walking lesson on why admiring the achievement does not mean that you also have to admire the man! To many, James Watson is the pioneering hero of Watson & Crick fame who brought us the landmark discovery of the double helix structure of DNA. But to an increasing demographic he is that unbearable bigoted dinosaur who often opens his mouth and leaves everyone else wishing that he hadn’t. Can you guess where I’m going with this yet? People have been in no doubt about Watson's general attitudes to those he considers inferior. Rosalind Franklin's overlooked contributions to the discovery of the double helix may not have been solely down to Watson, but the disrespectful account that he gives of her in his book “The Double Helix” leaves no readers in any doubts as to his opinions. Having already been expelled from his chancellorship of New York's Cold Spring Harbour Laboratory in 2007 for classic points of view such as being “gloomy about the prospect of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours, whereas all the testing says, not really” Watson said that while he hopes everyone is equal, “people who have to deal with black employees find this not true”. Wow! Watson did manage to limit the damage at the time by apologising for his statements but the same institution who took action against him in 2007 has now revoked all titles and honours that were once bestowed on him after his comments on a recent documentary. When asked if his opinions had changed on the matter he said “Not at all. I would like for them to have changed, that there be new knowledge that says that your nurture is much more important than nature. But I haven’t seen any knowledge. And there’s a difference on the average between blacks and whites on IQ tests. I would say the difference is, it’s genetic” In case anyone is in doubt, I would like to clarify that it is not. According to genetics there is not even any empirical support for the idea of race. More genetic variation is seen within races rather than between them. Yes middle aged white academic men do perform best in IQ tests but that is mainly because IQ tests were invented by middle aged white academic men. It doesn't mean that white men are more intelligent, it just means that they are better at IQ tests, which are already highly questionable as to their effectiveness at measuring what is really a very abstract collection of skills! Rant over, now breathe. With Tom not here I don’t want to be the host who takes over screaming into the void. And I’d just like to remind everyone that you have not been listening to the Ass-Hole of the Month feature. This is just the news!] Note about the Asshole of the Month that I’ll share with audience: the reason we’re not doing that is because it has become redundant during these years of the Trump Presidency. <a href= "https://www.nytimes.com/2019/01/11/science/watson-dna-genetics.html"> New York Times</a>, <a href= "https://www.theguardian.com/world/2019/jan/13/james-watson-scientist-honors-stripped-reprehensible-race-comments">The Guardian</a> <hr class="wp-block-separator" /> <h3>Elon Musk Reveals SpaceX's New Retro Test Rocket</h3> <h4>Nevena Hristozova</h4> Elon Musk keeps trying to bring us to Mars and this time, he’s doing it in retro style. SpaceX revealed a model of a sub-orbital flight craft for vertical take off and landing which looks like one from the 1950’s film Destination Moon. The prototype should be ready for test-flight in June, so keep your eyes open, people. SpaceX also plans the development of an orbital ship of the same class, which will be taller and with slightly different geometry to facilitate actually going into orbit. Both are the new generation space-craft from SpaceX which inherit the work done by Falcon Heavy, and are from a production line called StarShip. To be honest, the rocket looks a bit too smooth to look real, but who knows – we might have had the right design already in the 50s’ science fiction movie. <a href= "https://techcrunch.com/2019/01/11/elon-musk-shows-off-the-assembled-starship-test-rocket/"> TechCrunch</a>, <a href= "https://www.newscientist.com/article/2190418-elon-musk-reveals-starship-test-rocket-that-looks-like-1950s-sci-fi/">New Scientist</a> <hr class="wp-block-separator" /> <h2>Pub Quiz</h2> The latest science news in quiz form.

093: Cricket Diplomacy
We ring in 2019 with news of lovelorn crickets, the far side of the moon, food allergies, and a new branch on a big tree. But the proverbial elephant in the room is the ongoing shutdown of the United States' government. <hr class="wp-block-separator" /> <h2>On This Week’s Show</h2> <ul> <li>The far side of the moon</li> <li>Food allergies?</li> <li>Remember those reports of sonic assaults by the Cuban government against US embassy staff? We have some surprise information about that.</li> <li>We close with some discussion about a new kingdom of life and what it really means</li> </ul> <hr class="wp-block-separator" /> <h2>Science News with Sophie McManus and JD Goodwin</h2> <h3>What Does China Want To Do On The Far Side Of The Moon?</h3> <h4>JD Goodwin</h4> On the 3rd of January China’s Chang’e 4 lunar explorer landed on the far side of the moon. This is the first time we’ve done a soft landing on that obscure part of the moon. Okay, so let’s talk about why the far side of the moon is so interesting. The moon is tidally locked to earth, that is, it doesn’t rotate in relation to our planet. We only see the one side of the moon, whether it’s illuminated or not. The far side is also geologically very different. The crust is much thicker and older, and consequently it has been struck with more rocks and asteroids. On our side of the moon we can see those dark areas, called mare. There are very few of those on the moon’s far side. Chang’e touched down in a 180km crater that itself is within another huge basin, the South Pole-Aitken Basin. This basin was formed when an asteroid perhaps 500km across slammed into the moon billions of years ago. A big hole in a big hole. Putting the lander at this location should give it access to some of the moon’s oldest rocks…kind of like being at the bottom of the Grand Canyon. And the lander is gonna examine and do science on these rocks. They also have a lunar penetrating radar which can map out and study the subsurface down to a depth of 100m. Being on the far side of the moon will also give the researchers a chance to look into the universe without being hindered by light from the earth. So to take advantage of this the lander has a low frequency radio telescope that will allow it to look at a frequency band that we can’t use on earth because of electromagnetic interference. And the Lunar Lander Neutrons and Dosimetry experiment. This experiment was created by researchers in Germany. It’s goal is to look at radiation on the moon in great detail so that humans will be able to shield themselves on future missions. So, watch this space! <a href= "https://www.bbc.com/news/science-environment-46748602">BBC Science and Environment</a> <h3>Many People Who Claim to Have a Food Allergy Actually Don’t</h3> <h4>Sophie McManus</h4> We probably all know people with a food allergy. Some of these allergies can be deadly, others more of an irritation or inconvenience. The most prevalent food allergens among U.S. adults are shellfish (affecting 7.2 million adults), milk (4.7 million), peanut (4.5 million), tree nut (3 million), fin fish (2.2 million), egg (2 million), wheat (2 million), soy (1.5 million), and sesame (.5 million). There’s some surprising news out this week that in fact many people who believe they have an allergy…don’t. A study was carried out in the US on 40,000 adults. 19% of these people stated they had an allergy to a type of food, whereas the researchers found that only 10% of them actually had an allergy. Bizarre! Lead study author Dr Ruchi Gupta is a paediatrics professor at the Northwestern University Freiburg school of medicine. Dr Gupta stated that symptoms may reflect food intolerances rather than true allergies. Genuine food allergies can of course be dangerous and should always be considered. But it seems as though a lot of us are simply intolerant, or deciding that we are, rather than really allergic. <a href= "https://www.livescience.com/64423-food-allergies-overestimated.html"> Live Science</a> <h3>The Sounds That Haunted U.S. Diplomats in Cuba? Lovelorn Crickets, Scientists Say</h3> <h4>JD Goodwin</h4> There were a lot of things happening back in late 2016. Lost in all that noise was the story of American diplomats who suddenly became ill in Havana, Cuba. They reported hearing various types of unpleasant sounds. This happened in housing maintained by the Cuban government as well as in hotel rooms. The personnel actually showed symptoms consistent with brain injury, although no head trauma of any kind was shown. U.S. officials immediately suspected that the Cuban government was behind this. Well…new research suggests there many be another reason. Crickets. Really loud ones. Recordings were made of these so-called attacks, and were released by the Associated Press. So some researchers took that recording and discovered that its parameters lined up perfectly with the Indies short-tailed cricket. And according to the researchers their findings, which have not yet been peer-reviewed, do provide strong evidence that crickets were indeed making the sound on the recording. Now that doesn’t rule out any nefarious activity by the Cuban government or others. But blaming the Cubans is not looking good at this moment. This was no small incident. The U.S. government expelled 15 Cuban diplomats from Washington as a result of this. All the while the Cuban government insisted that it had nothing to do with any of this. In fact, they even worked with U.S. investigators to determine the cause of the health issues. <a href= "https://www.nytimes.com/2019/01/04/science/sonic-attack-cuba-crickets.html"> New York Times</a> <h3>What a Newfound Kingdom Means for the Tree of Life</h3> <h4>Sophie McManus</h4> Recently, researchers found a rare microbe called a hemimastigote in a remote area of Canada. Analysis of its DNA led to the startling finding that this organism represents a different class of life altogether – its genetic material was distinct from any animal, microbial, plant, fungal or protozoan. This discovery therefore represents a new and startling branch in the tree of life. The PhD student who made this finding is Yana Eglit. When she was hiking in Novia Scotia back in 2016 she stopped to take a sample of the soil (she terms this behaviour a ‘professional hazard’). Back in the lab she soaked it in water and kept an eye on it through the microscope for a few weeks. Eventually she noticed movement, from a single elongated cell in the sample, covered with flagella. She thought it might be a hemimastigote and the lab all got involved to investigate further. The subsequent work showed that this organism represented its own pocket of life as we know it. The reason the researchers can be sure this represents a distinct branch lies in technology. Single-cell transcriptomics has revolutionized such studies – this approach enables researchers to sequence large numbers of genes from just one cell. For for hard-to-study organisms like hemimastigotes, single-cell transcriptomics can produce genetic data of a quality previously reserved for more abundant cells, making deeper genomic comparisons finally possible. The team sequenced more than 300 genes, and <a href= "http://www.ettemalab.org/laura-eme/">Laura Eme</a>, a postdoc at Uppsala University in Sweden, modelled how those genes evolved to infer a classification for hemimastigotes. “We were fully expecting them to fall within one of the existing supergroups,” she explained. Lab members were instead stunned to find that hemimastigotes fit nowhere on the tree. They represented their own distinct lineage. It has been termed ‘the sort of result you hope to see once in a career’ by lead scientist Alistair Simpson, of Dalhousie University. The tree of life has changed an awful lot in the last couple of decades, and it seems likely this change will continue. Darwin would be fascinated! <a href= "https://www.quantamagazine.org/what-a-newfound-kingdom-means-for-the-tree-of-life-20181211/"> Quanta Magazine</a> <hr class="wp-block-separator" /> <h2>The Climate Lounge</h2> <h3>The Lounge is SHUT DOWN!</h3> <h4>Tom Di Liberto</h4> Podcast listeners, the Climate Lounge piece you are trying to access is not available at this time due to a lapse in appropriation…and judgment…and decency. [silence] Ok, just kidding. That only applies to small things like the place I work and 800,000 federal employees of the United States. Yay. You all might be thinking, “This seems dumb, why are they doing this? Or perhaps “What does this mean for science”. (more likely the first one but I’ll talk about both. For listeners outside the United states who might not be aware of what’s going on in the US right now, in late December, funding ran out for parts of the federal government. How could this happen? Well, the US government was on the verge of funding everything including a unanimous vote in the US Senate. Then Fox and Friends and other far right media folks got pissy and the president decided he wasn’t going sign the bill without funding for an idiotic (and environmentally disastrous) border wall. And shut the government down. This meant that hundreds of thousands of workers either were forced to stay at home and not work, or forced to work, all without pay. The problem being of course, that while most folks will get paid for the time they missed, bills are still due when they are due. But this is a science podcast so let’s briefly touch on the science and environmental impacts. For one, the national parks have been kept open, but with a hugely reduced or non-existent staff. This means that folks can come in and do whatever they want. And they are. Trash is overflowing, toilets clogged, human waste left…anywhere and trespassing aplenty. This will have long-lasting impacts on the natural environments that draws people to the parks in the first place. Science-wise, for folks like me, the largest conference of meteorologists in the country, the meeting of the American Meteorological Society is taking place sans 700 federal employees, meaning the schedule took a huge hit as tons of talks were scrapped, meetings impacted, and conversations silenced. But some folks (dumb folks) would say oh that just’s a trip BOONDOGGLE! Not folks who listen to this podcast of course, but some folks. To those people I also will note that scientists are not allowed to check experiments that are currently ongoing, potentially ruining them. They are not allowed to perform observations, collect data, conduct tests, or share their results. That fieldwork trip? Unless it was forward funded, CANCELED. We are legally not allowed to science. Heck, we can’t READ science in some cases too with proposals left unread. For me, I’m lucky for now. My contract is forward funded so I can work, from home, as long as I have tasks to do. But geez is it hard. I’m still making forecasts for major climate patterns with global implications knowing that if something breaks, a model doesn’t run, a product can get the right data, that there will be no one to fix it because they are furloughed. I know that even with a good forecast, our ability to do outreach on what it means will be hampered. It’s all so very very very stupid. Now if you’ll excuse me, I’m going to continue my 2018 tradition into 2019, by screaming into the void. <hr class="wp-block-separator" /> <h2>Pub Quiz</h2> The latest science news in quiz form.

092: Gabriela Montejo-Kovacevich
 The best in science communication tells a compelling story, and this week we have a great one! Gabriel Montejo-Kovacevich joins us to talk about her research in Central and South America studying butterflies of the genus Heliconius, also known as longwings. She shares her story of the hard work and the gratifying rewards of field research in challenging conditions. Gabriela is at the front line of science, and we are grateful to her for sharing her adventure and her research with us.   <hr class="wp-block-separator" />   <h2>On This Week’s Show</h2>   <ul> <li>Science News of the Week</li> <li>The Pub Quiz</li> <li>Interview: Gabriela Montejo-Kovacevich of the University of Cambridge</li> </ul>   <hr class="wp-block-separator" />   <h2>Science News with Nevena Hristozova and Sophie McManus</h2>   <h3>NASA’s Voyager 2 Probe Leave the Solar System</h3>   <h4>Nevena Hristozova</h4>   “Houston, I’m out of here” is probably what Voyager 2 said when it officially left the Solar System and is now roaming in the deep space between stars.   The craft was launched before Voyager 1. It may seem counter-intuitive, but it was set on a different trajectory that Voyager 1, so it left our star space 6 years after Voyager 1 did, hence it was already originally planned as Voyager 2.   Why is this a big deal? For many reasons:   <ul> <li>The twin crafts are the furthest existing man-made objects in the universe. They are (at the time of the recording) at more than 21 billion kilometres away.</li> <li>They are the first man-made objects to leave the solar system.</li> <li>They keep working - this is how we knew they have left the solar system - the instruments on board are measuring the density of solar particles and when a drop in this density was observed, scientists knew they are out! It was a bit of a strange experiment, since the astronomers were expecting them to stop detecting stuff, which is a hard thing to anticipate since at the edges of the system stuff is very far from each other to begin with.</li> <li>The Voyagers upped the bets of everyone - their original mission was to explore the outer planets of the solar system, but they just kept going and going and their instruments kept working so the project scientists were just not going to quit until the Voyagers did so they kept collecting data and analysing it.</li> </ul>   Next up for the twins is a minefield of comets loosely gravitationally bound to our Sun. Hopefully they won’t meet their demise there, but even if they do - they’ve done so much more than anyone expected from them that it’d be a well deserved rest.   If they survive that hurdle, they will be orbiting the center of our galaxy for billions of years and it will take Voyager 1 another 40,000 years to reach another star system despite its looming speed of 61,000 kilometres per hour.   <a href= "https://www.bbc.com/news/science-environment-46502820">BBC Science and Environment</a>, <a href= "https://www.latimes.com/science/sciencenow/la-sci-sn-voyager-2-interstellar-space-20181210-story.html"> LA Times</a>   <h3>The Great Barrier Reef is Fighting Back</h3>   <h4>Sophie McManus</h4>   We’ve spoken at length about the horrific bleaching happening on the GBR, the world’s largest coral reef. Coral reefs are vast colonies of hard coral, an organism which extracts calcium carbonate from seawater to construct a limestone structure for protection. The tiny animals in coral are clear. They get their bright reds and vivid purples from colourful algae called zooxanthellae that live in their cells, providing the oxygen that the corals need to grow — albeit slowly. Coral reefs, which by some estimates support a quarter of all ocean life, are harmed by warming oceans. Bleaching occurs when the ocean temperature rises. If prolonged, bleaching causes coral to die. And this was the case last year and the year before last. The 2,300 kilometre long reef was severely bleached by back-to-back heatwaves in early 2016 and early 2017, causing half the coral to die.   Aerial surveys led by researcher Terry Hughes at James Cook University show that the Great Barrier Reef survived last year’s extreme summer better than the previous year’s, hinting that it is becoming more resilient. However, some coral species are faring better than others, meaning the reef is likely to look very different in years to come.   “Despite the fact that 2017 was hotter, we saw less bleaching over all across the whole reef,” Dr. Hughes said. The reason, he said, was a novel concept scientists call ecological memory: the idea that the past experience of a biological community can influence its ecological response today or in the future.   This sounds good news for the Reef, but doesn’t change the fact that in order to recover as much as possible from a bleaching event a reef needs 10 years. With rising ocean temperatures becoming more common, the world’s coral is set for more bleaching and death in years to come, which doesn’t only represent an avoidable human tragedy, but an ecological disaster.   This research is published in Nature Climate Change.   <a href= "https://www.newscientist.com/article/2187654-the-great-barrier-reef-is-fighting-back-by-losing-weak-species/"> New Scientist</a>, <a href= "https://www.nytimes.com/2018/12/10/climate/coral-reefs-natural-selection.html"> New York Times</a>   <h3>Seals Keep Getting Eels Stuck Up Their Noses</h3>   <h4>Nevena Hristozova</h4>   I’ve been congested for three weeks now and I can tell you it’s super annoying! So I truly commiserate with the poor seals who keep getting something far worse stuck up their noses - eels! That’s right they are figuratively snorting unagi-sushi!   The Hawaiian Monk Seal Research Program informs via the website Live Science that a live eel getting stuck up a seal nose is not a unique case.   The monk seals feed on or near the bottom of the ocean. So, they go for the food, for example eels, whose strategy is to hide at the bottom of the ocean.   Scientists don’t know how the eel got up its nose - it could have, rammed itself into the nostril and maybe got stuck in the heat of an attempt to escape. Or may be the seal brought the eel out to the surface to eat the prey, and the eel could have whipped around and got into the nose…   It can be also a case of “not knowing better” since this phenomenon has been observed only in young seals, who might just be inexperienced at hunting.   Or the seal might have sneezed or regurgitated the eel through the wrong pipe.   Not to worry though - the seal’s day turned for the better as researchers managed to remove it from its nose. The eel however did not have the same luck as it died. Maybe it got a fatal scare of how dark the nose of the seal was?   <a href= "https://www.livescience.com/64249-seal-eel-stuck-nose.html">Live Science</a>   <h3>River Bounces Back After World’s Largest Ever Dam Removal</h3>   <h4>Sophie McManus</h4>   After my hideously pessimistic take on the last story it is time for some optimism.   Freed from two large dams, a small river in Washington state USA has efficiently flushed vast amounts of mud, sand and gravel towards the sea.   This is the world’s largest dam-removal project so far. Two barriers on the Elwha River (32 and 64 metres high respectively) were dismantled between 2011 and 2014 to restore the river’s flow. Amy East at the US Geological Survey in Santa Cruz, California, and her team monitored river flow and topography before, during and after the dams’ removal.   The release of 20 million tonnes of sediment that had been trapped in the reservoirs behind the dams substantially altered the shape of the river, filling pools and creating new sandbanks. But five months later most of the change had settled down and the 20 million tons of debris had in the main reached the Strait of Juan de Fuca.   Rivers of sufficient stream power seem to be able to cope with large dam removals without serious harm, the authors conclude. I assume this is good news for recovery of various ecosystems and species supported by the river. I looked into how dams affect rivers.   Notes from <a href= "https://www.internationalrivers.org/environmental-impacts-of-dams"> https://www.internationalrivers.org/environmental-impacts-of-dams</a>   The dam wall itself blocks fish migrations, which in some cases and with some species completely separate spawning habitats from rearing habitats. The dam also traps sediments, which are critical for maintaining physical processes and habitats downstream of the dam (include the maintenance of productive deltas, barrier islands, fertile floodplains and coastal wetlands).   Another significant and obvious impact is the transformation upstream of the dam from a free-flowing river ecosystem to an artificial slack-water reservoir habitat. Changes in temperature, chemical composition, dissolved oxygen levels and the physical properties of a reservoir are often not suitable to the aquatic plants and animals that evolved with a given river system. Indeed, reservoirs often host non-native and invasive species (e.g. snails, algae, predatory fish) that further undermine the river's natural communities of plants and animals.   The alteration of a river's flow and sediment transport downstream of a dam often causes the greatest sustained environmental impacts. Life in and around a river evolves and is conditioned on the timing and quantities of river flow. Disrupted and altered water flows can be as severe as completely de-watering river reaches and the life they contain. Yet even subtle changes in the quantity and timing of water flows impact aquatic and riparian life, which can unravel the ecological web of a river system.   A dam also holds back <a href= "https://www.internationalrivers.org/node/2221">sediments</a> that would naturally replenish downstream ecosystems. When a river is deprived of its sediment load, it seeks to recapture it by eroding the downstream river bed and banks (which can undermine bridges and other riverbank structures, as well as riverside woodlands). Riverbeds downstream of dams are typically eroded by several meters within the decade of first closing a dam; the damage can extend for tens or even hundreds of kilometers below a dam.   IN SUMMARY Large dams have led to the <a href= "https://www.internationalrivers.org/node/1314">extinction</a> of many fish and other aquatic species, the disappearance of birds in floodplains, huge losses of forest, wetland and farmland, erosion of coastal deltas, and many other unmitigable impacts.   I realise we use dams to prevent floods, hence reduce the occurrence of natural disasters affecting human life. (Although the 3 Gorges Dam on the Yangtze river led to the displacement 1.3 million people and led to the loss of many cultural sites.) Another great benefit of dams is the hydroelectric power they can generate, providing cleaner energy than fossil fuels.   <a href= "https://www.nature.com/articles/d41586-018-07707-0">Nature Geophysics</a>   <hr class="wp-block-separator" />   <h2>Interview: Gabriela Montejo-Kovacevich of the University of Cambridge</h2>   <div class="wp-block-image size-full wp-image-1604"><img class= "wp-image-1604" src= "https://bluestreakscience.com/wp-content/uploads/2018/12/GMKOV.png" alt="" /> Gabriela Montejo-Kovacevich</div>   A PhD candidate in Zoology at the University of Cambridge.

091: Fourth National Climate Assessment, and more
A year ago we were in shock and disbelief in the days after the Tubbs Fire in Northern California incinerated our neighborhood, and our home. One year later and that scene of apocalyptic devastation has been replaced by a community coming together and rising from the ashes. I'm overjoyed to announce that we can put that awful year behind us. My family and I have moved back into our wonderful neighborhood, and we're looking forward to more and more of our neighbors' return. A million thanks to the Blue Streak Science team. You are simply the best. I'm indebted to you, and it's my honor to work on this project with you. Thanks to our incredible audience for sticking with us during the past year. For you, we pledge to take the Blue Streak Science Podcast to the next level. The future is gonna be awesome! <h2>On This Week’s Show</h2> <ul> <li>The science news of the week</li> <li>The Climate Lounge with Tom Di Liberto</li> <li>And the Pub Quiz</li> </ul> <hr /> <h2>Science News with Dr. Amrita Sule and Sophie McManus</h2> <h3>Cosmic Airburst May Have Wiped Out Part of the Middle East 3,700 Years Ago</h3> We all have seen shooting stars at night. Millions such small asteroids are thought to orbit on paths that bring them near Earth. So, once in a while as noted in history a comet or a meteorite can come very very close to the earth surface and explode - causing massive destruction events called cosmic airbursts. A team of researchers from Jordan’s Tall el-Hammam Excavation Project have found evidence that a cosmic airburst took place about 3,500 years ago. This explosion of a comet or a meteor destroyed around 500 square kilometers, wiping out all human life and a vast area of fertile land north of the Dead Sea called Middle Ghor. This airburst left the fertile lands barren as they were deposited with anhydride salts from the Dead Sea due to a tsunami which was caused by the aftershocks from the airburst. It took almost 600 years for the area to recover before any civilization could be restored. How did the archeologists come across the evidence of this airburst? They found and studied 3,500 year old pieces of pottery from the Tall el-Hammam excavation site and discovered that it was vitrified, turned into glass. This would require extremely high temperatures around 4,000˚ C. Just for reference the temperature on sun is about 5,600˚ C. This was so powerful that zircon contained in the pottery turned into glass. Radiocarbon dating at the site indicated that mud-brick walls “suddenly disappeared around 3,700 years ago, leaving only stone foundations.” A similar air burst that took place in Tunguska, Siberia in 1908 had a blast radius of 2,000 square kilometers, suggesting that the explosion which destroyed the Middle Ghor region occurred at a low altitude, possibly not more than one kilometer above the ground. The most recent airburst took place in February 2013 when a meteor exploded over Central Russia. This event injured about 1,500 people and damaged thousands of buildings. These cosmic airbursts continue to be an impending threat to the planet. Scientists are working on developing warning and response systems to deal with such cosmic events. <a href= "https://www.livescience.com/64179-ancient-cosmic-airburst-middle-east.html"> Live Science</a> <h3>Fox, 'Cosmos' Producers Investigate Sexual Misconduct Claims Against Host Neil deGrasse Tyson</h3> [caption id="attachment_1591" align="alignright" width="300"]<img class="size-full wp-image-1591" src= "https://bluestreakscience.com/wp-content/uploads/2018/12/91_300x400NdGT.png" alt="" width="300" height="400" /> Neil deGrasse Tyson[/caption] Neil deGrasse Tyson has been accused by three women of sexual misconduct and an investigation will take place shortly. In one allegation, Katelyn Allers, an associate professor of astronomy and physics at Bucknell University in Pennsylvania, claimed Tyson inappropriately touched her in 2009 while admiring a space tattoo on her upper left arm. Another woman, Ashley Watson, claimed that she quit a position as Tyson's assistant due to inappropriate sexual advances. Those claims follow an earlier allegation by musician Tchiya Amet, who claimed Tyson raped her while both attended graduate school. deGrasse Tyson has written a piece addressing the claims titled ‘On Being Accused’. "I'm the accused, so why believe anything I say? Why believe me at all?" Tyson wrote. "That brings us back to the value of an independent investigation, which FOX/NatGeo (the networks on which Cosmos and StarTalk air) announced that they will conduct. I welcome this. … Accusations can damage a reputation and a marriage. Sometimes irreversibly. I see myself as loving husband and as a public servant – a scientist and educator who serves at the will of the public. I am grateful for the support I’ve received from those who continue to respect and value me and my work.” Trial, or rather manhunt, by social media is ridiculous, so it’s good that Fox and NatGeo are getting on with an investigation. I read both Degrasse Tyson’s account and one of the blogs detailing the assault, for this story. I have my own opinion, but given that I’ve just denounced trial by social media I think I’ll keep it to myself…! <a href= "https://www.nytimes.com/2018/12/01/arts/neil-degrasse-tyson-sexual-misconduct.html"> New York Times</a>, <a href= "https://www.space.com/42606-fox-cosmos-investigate-claims-against-neil-degrasse-tyson.html"> Space.com</a> <h3>As Natural As Spider’s Milk</h3> The kingdom Animalia never ceases to surprise us. And one of the recent discoveries is about jumping spiders, Toxeus magnus. According to a study published in Science, Female Toxeus Magnus spiders secrete a milk like fluid to feed their offspring. But wait! Spiders are not mammals, and isn’t breastfeeding is fundamental to being mammals? Apparently not. Over time scientists have discovered that animals such as flamingos, cockroaches and male emperor penguins produce nutrient rich milk-like substances to feed their young. The discovery that Toxeus magnus spiders secrete a milk-like fluid was carried out by lead author Zhanqui Chen of the Chinese Academy of Sciences. Chen observed that young T. magnus spiders were slow to leave their breeding nests – suggestive of extended childcare. Chen's team noticed in the lab that the newborns and the mother remained in the next for about 20 days. A closer they revealed that during first week the mother deposited droplets of white fluid from her underside on to the nest, which the newborns would drink. After that the newborns directly drank from the underside of the mother. The mother continued to provide milk for 20 more even when the young spiders would leave their nests to forage. These young spiderlings returned to the nest for mother’s milk until finally weaning at 40 days of age. When Chen blocked the opening (same when they lay eggs) from which the fluid was secreted, the hatchlings did not survive beyond 11 days which shows their complete dependence on this fluid. Chen and colleagues found that this milk like white fluid was extremely rich in proteins. It contained four times as much protein as cow’s milk. The authors are okay with calling this fluid spider’s milk even though it does not come from a mammary gland. They are more interested in how it supports the offspring. Chen and colleagues plan to study how does T. magnus generates this fluid. This discovery challenges the dogma that lactation is uniquely a mammalian trait. They don’t know yet if this is seen in any other spiders. These rare variants in the animal kingdom will help in providing insights about evolution of lactation and parental care. <a href= "https://www.nytimes.com/2018/11/29/science/spiders-milk.html">New York Times</a> <h3>Researcher who created CRISPR twins defends his work</h3> Lots to think about here. Let’s refresh briefly on what exactly has happened. A few days ago, a researcher in China claimed to have CRISPR-edited human embryos to prevent them from contracting HIV. He Jiankui of the Southern University of Science and Technology in nearby Shenzhen, China, said he was “proud” of the work, which he said could lead to disease prevention “for millions of children.” While CRISPR technology has been used in a preliminary way in human material, what’s truly controversial about this work is the claim that the edited embryos were allowed to develop to term. That’s right - this work apparently resulted in the birth of two babies. The announcement he had done this was only made when the twin girls had been born. Earlier this week, He announced in an Associated Press (AP) interview and a series of YouTube videos that his team had engineered the genomes of twin baby girls to cripple a key receptor, CCR5, that HIV uses to infect white blood cells—a modification they may pass onto their descendants. Mutations in the CCR5 gene confer HIV resistance, and He said previous experiments have suggested CCR5 was a promising target for editing. But He didn’t explain how gene editing could help the world prevent the disease; nobody thinks it’s feasible to edit the genomes of entire populations. Several things to consider. Did this work actually happen? Or is it a poorly judged attempt at some sort of fame/notoriety? If the researcher indeed edit human embryos which were then born, what has this work done to them other than (possibly) mediating their risk of contracting HIV? A long-winded way of saying, what other stuff has he messed with?! CRISPR is known as an incredible tool to modify genetic information, but it is also known to cause many undesirable off-target effects. Did the parents really understand what was being done? Apparently He claimed this work was part of a vaccine development project to some potential patients. For any listeners unfamiliar with the furore surrounding the potential of CRISPR, this work represents a lot of controversy. This technique isn’t considered clinically safe. Nor have we reached any consensus on whether it is morally acceptable to tamper with the genome of human embryos. Particularly otherwise HEALTHY embryos. The phrase ‘playing God’ is likely to be bandied about. The water is murkier still. Perhaps unsurprisingly, given the huge moral repercussions of gene editing human embryos, it appears this work was not funded or sanctioned by the scientist’s research institution. They are now investigating him! Another point worth making is - who’s going to publish this? Reputable journals would be likely to reject this work on ethical grounds alone. He says the work has been submitted to a peer reviewed journal, but many unanswered questions remain, for example which hospital he did the work at, why he hadn’t mentioned this work earlier (for example when the woman was pregnant), what success rate he found, what adverse effects may have arisen in failed attempts. Back to the actual aim of this work, to make the girls resistant to contracting HIV. But, I mean, were they at risk of contracting HIV in the first place? Why alter ostensibly healthy embryos while risking off-target genetic effects? Even if they are exposed to HIV, which they have been ‘edited’ to avoid, you know they COULD still get it. I mean some people are naturally immune to HIV, but they STILL can get it, if it gets through an alternative route!!! There are ways to avoid HIV that don’t involve gene editing! This isn’t an unmet medical need. There’s no way to prove that this work has benefitted the girls, as if they don’t catch HIV, that isn’t necessarily because of He’s work! I’ll close with some comments made by Jennifer Doudna, one of the inventors of CRISPR as we know it today. Doudna is ‘horrified’ by this story, if it is true. If you want to know more about the fallout, I recommend a great Atlantic article by Ed Yong titled <a href= "https://www.theatlantic.com/science/archive/2018/12/15-worrying-things-about-crispr-babies-scandal/577234/"> The CRISPR Baby Scandal Gets Worse By The Day</a>. <a href= "https://www.sciencemag.org/news/2018/11/researcher-who-created-crispr-twins-defends-his-work-leaves-many-questions-unanswered?rss=1"> Science</a> <hr /> <h2>The Climate Lounge</h2> United States National Climate Assessment and the start of COP24 Tom Di Liberto It’s good to be back in The Lounge. A lot has happened since I last ranted….I promise I’m going to try and rant less and hope more. So instead of trying to cover every specific last thing that’s happened climate-related on this planet, I’m going to talk about a broad new report that was recently released by the US Government, the Fourth National Climate Assessment. First a disclosure, everything I say is my own opinion and does not reflect upon my employer. Also, I work at one of the agencies that helped produce the report but I did not have a hand in making it. With that said, let’s get into it. The Fourth National Climate Assessment was released on Friday, 23 November, better known as the day after Thanksgiving, which sigh…obviously was done to reduce the number of eyeballs paying attention. WHY would this have been done? Well, let me read verbatim what is under the "Communities" header in the summary findings “The impacts of climate change are already being felt in communities across the country. More frequent and intense extreme weather and climate-related events, as well as changes in average climate conditions, are expected to continue to damage infrastructure, ecosystems, and social systems that provide essential benefits to communities. Future climate change is expected to further disrupt many areas of life, exacerbating existing challenges to prosperity posed by aging and deteriorating infrastructure, stressed ecosystems, and economic inequality. Impacts within and across regions will not be distributed equally. People who are already vulnerable, including lower-income and other marginalized communities, have lower capacity to prepare for and cope with extreme weather and climate-related events and are expected to experience greater impacts. Prioritizing adaptation actions for the most vulnerable populations would contribute to a more equitable future within and across communities. Global action to significantly cut greenhouse gas emissions can substantially reduce climate-related risks and increase opportunities for these populations in the longer term.” This report is following the science and because of that is pulling no punches. You might be thinking how in the world was this released by the current US government? Well, the National Climate Assessment is a Congressionally mandated report that comes out roughly every 4 years by law. This report has been in the process of creation starting before the current administration took office and they had no right to stop it. Now, for our international listeners, this report does NOT go into the global impacts currently and in the future of climate change. Instead, it has a specific focus on how climate change is impacting and will continue to impact the United States (and all that entails). It looks at all scenarios for the future and explains what will happen to extreme weather impacts, climate change impacts on coastal, interior, mountains…you get the picture. In fact, it breaks down the US into regions and each region gets its own section to discuss impacts. It is a thorough and massive effort done by tons of scientists, a lot of whom did this in their free time not getting paid a scent. Now the reaction to this release has been predictable. With fabrications, deflections and did I mention fabrications? A lot of lies out there trying to downplay this report's conclusions....including insisting it wasn’t based on data. Uhmm, it’s basically all data! Each statement has a citation after it leading to a peer reviewed journal article. It’s a data nerd's dream! Or that scientists were getting rich off of this. Which, HAHAHA, oh lord that’s a good one! Or that it was only based off a worst case scenario. It wasn’t. But you get this picture. Now they tried to bury this report so I think all Americans should do our part to keep talking about it. It also includes sections on what to do about the problem, and reducing risks which are great things to focus on. Solutions are good, people. Because climate change isn’t going away and it’s going to get worse. Now before I leave, I’d be silly not to mention that the annual UN Conference on Climate Change or COP24 is taking place currently in Poland. I recommend folks google searching stories about it and following those journalists and activists in Poland for the latest news. And check back to the lounge in the future for a run down of what went down. (psst, Poland had coal companies sponsor the event including have multiple coal displays...I’m not joking…goodness). There will be a lot to talk about, including some amazing efforts globally by the world’s youth to force action.

What can go wrong? Pretty much everything when you are sitting on several hundred litres of highly flammable fuel. On 11 October this is exactly what went wrong. Two astronauts were on their way to the ISS in a rocket powered by the Soyuz engines when a problem in the detachment of one of the stages caused the rocket to plunge back to earth, not only before it delivered the cosmonauts to the ISS, but in a trajectory less like the one of a space vessel, but more like a ballistic rocket. And if you are in that thing you really don’t want to be falling like a bomb down to Earth. Luckily, the Russian and American astronauts were well prepared with their training because they employed some 20-year old emergency training techniques which saved their buts. While landing they experienced forces that normally astronauts are not supposed to feel at any stage of the flight. Such forces that an average-weight person would feel like 10 times heavier. Both of them seem to be well and kicking, but there will be an investigation on what exactly happened, why and how to avoid it in the future. <a href= "https://www.livescience.com/63804-soyuz-iss-launch-abort.html">Live Science</a>, <a href= "https://www.space.com/42134-soyuz-launch-abort-eyewitness-video.html"> Space.com</a> <h3>Neanderthal Child Eaten by Giant Bird</h3> <h4>Amrita Sule</h4> Imagine getting your hand or finger chewed off by a bird of prey. Ouch!! Sounds kind of painful isn’t it? About 115 thousand years ago a Neanderthal child wasn’t having a very good day. Archaeologists have found two finger bones- about an inch in size, from the hand of a Neanderthal child aged about 5-7years. In a press release Paweł Valde-Nowak from the Institute of Archeology of the Jagiellonian University in Kraków said that the bones were dotted with holes – which could be a result of passing through the digestive system of a large bird. It is difficult to say if the bird just chewed off the child’s fingers , killed the child or just happened on its body and scavenged its remains. Theses bones were discovered at the Jaskinia Ciemna cave in Poland and are the oldest hominid remains found in that area. They were found a few years ago but only now after in depth analysis the researchers are confident of its Neanderthal origin. They were found in a deep cave a few meters below the present earth surface. However,the bones are too deteriorated for any DNA analysis. This is of interest because Neanderthal remains are very rare in this area. Tools such as knife and scrapers, which could be used to cut and scrape dating back to about 220 thousand years have been found in Poland. Priors to this the oldest remains found in Poland were 3 Neanderthal molars dating to 55-40 thousand years ago. These discoveries mostly come from Southern Poland suggesting that this region was more favored by the Neanderthals as opposed to the northern which was covered by glaciers during ice age. Discovery of these finger bones is so far the only evidence from the last ice age in this area. <a href= "https://www.smithsonianmag.com/smart-news/poor-neanderthal-child-was-eaten-giant-bird-180970524/"> Smithsonian.com</a>, <a href= "https://www.livescience.com/63801-giant-bird-ate-neanderthal-child.html"> Live Science</a>, <a href= "https://www.thefirstnews.com/article/oldest-bones-ever-found-in-poland-and-dating-back-115000-years-belonged-to-neanderthal-child-whose-fingers-were-chewed-by-a-giant-bird-2561"> The First News</a> <h3>Hawking's Final Science Study Released</h3> <h4>Nevena Hristozova</h4> Professor Hawking will continue to tease the minds of us - poor simpletons still alive with his science from beyond the grave for really long time. He was SO smart, that his work will be tested, and retested, and his theories proven and revised for at least a hundred years ahead, I bet on that! Anyway, the last paper Prof Hawking worked on and submitted before his death was recently published. It deals with nothing less, but the possibility for Black Holes to retain information on the objects once they pass the point of no return and are ripped apart to energy and a little nothingness. In his paper, Hawking built on the work of another genius whose work we are not even halfway through tackling - Einstein. According to their theories, and contrary to the popular knowledge that NOTHING escapes black holes, they (black holes) have temperature. Which in physics means that they release energy in the form of heat. The principle that each physical system loses part of its energy in the form of heat is thought even in school and is known as entropy - the strive of everything in the universe to eventually dissolve into chaos. This would mean that eventually a black hole should run out of energy to release and thus seize to exist. This, if valid for black holes too imply that every piece of information (which is in essence energy, as property of an object) will eventually get destroyed in the process of evaporation of the black hole. Hawking’s article, or rather the math in it, shows that the event horizon’s bright edges might be actually accounting for that entropy. <a href= "https://www.bbc.com/news/science-environment-45826748">BBC News Science and Environment</a>, <a href= "https://www.sciencemag.org/news/2018/10/hawking-s-final-paper-posted"> Science</a> <h3>Increase In Cases of Rare 'Polio-Like' Illness in the US</h3> <h4>Amrita Sule</h4> This year, more than half of the states in United States have reported cases of a polio like rare disease called acute flaccid myelitis or AFM. It mainly affects children. AFM was first identified in 2014 – which saw 120 cases. According to CNN in this year as of Oct 16th there have been 47 confirmed cases and 49 more that were suspected or being investigated, for a total of 96. According to Centers for Disease control and prevention (CDC),AFM is very rare – affects less than 1 in a million. AFM affects a person’s nervous system, specifically the spinal cord. Like some neurological conditions, AFM can have a variety of causes such as viruses, environmental toxins, and genetic predisposition. The symptoms are usually sudden weakness in arms and legs, facial drooping, difficulty swallowing, sudden inability to speak - similar to complications of infection with certain viruses, including poliovirus, non-polio enteroviruses, adenoviruses, and West Nile virus. According to NIH, AFM- related viral infections can be prevented by staying upto date with Polio-vaccines. Treatments like, Immunoglobulin, corticosteroids, plasma exchange and antiviral therapy have been tried. There is no cure as far we now. Some patients recover quickly, while others may need long-term care. Physical and occupational therapy are important for recovery. <a href= "https://www.livescience.com/63803-acute-flaccid-myelitis-us-cases-2018.html"> Live Science</a> , <a href= "https://www.cnn.com/2018/10/15/health/acute-flaccid-myelitis-cases-states/index.html?utm_term=image&utm_medium=social&utm_source=twCNN&utm_content=2018-10-16T00%3A52%3A04"> CNN</a>, <a href= "https://rarediseases.info.nih.gov/diseases/13142/acute-flaccid-myelitis"> NIH</a> <hr /> <h2>The Blue Streak Science Endorsements for Congress</h2> Since the early 1990’s there’s been a rising tide of anti-science growing in the United States. Religious groups, predominantly evangelical Christian, have fought to remove science from public classrooms. Thankfully, their efforts have mostly failed judicial review. Still, they keep coming. Their strategies change, but the goal is the same: the complete removal of any science that doesn’t comport with their particular brand of theism. In recent years this anti-science evangelical movement has piggy-backed on, and reaped the benefits on the alarming upsurge in white nationalism and racism in the United States. They were rewarded in 2016 with an amazing trifecta, the election of a Republican House, a Republican Senate, and the grand prize, the election of Donald Trump as President of the United States. Unsurprisingly, in this new government’s view making America great again meant doubling down on the removal of any inconvenient and offensive science from their decision making process. The have repeatedly called climate change a hoax; hoax that is being perpetuated by China. They’ve appointed numerous science deniers to key positions in the government. They’ve slashed scientific research budgets and attacked everything from the Clean Air Act to the Endangered Species Act. Trump pulled the United States out of the Paris Climate Accord, and completely relinquished our leadership role in reversing climate change as well as squandering our opportunities in the green energy marketplace. This shock to the system has motivated scientists all over the world to stand up and mobilize to not only save science, but to save democracies. This is a pivotal moment in our history. As a result, women and scientists have run for Congress in 2018 in numbers never seen before. And we at Blue Streak Science want to make sure that you’re aware of some of the outstanding scientists, and science-friendly candidates we have running for Congress. This isn’t even close to being a comprehensive list, but here we are featuring some of the more stand-out candidates...candidates we are proud to endorse. Candidates that we urge you to vote for. <h3>Sean Casten</h3> <a href="https://castenforcongress.com/">Support Sean Casten</a> <img class="alignright wp-image-1532 size-medium" src= "https://bluestreakscience.com/wp-content/uploads/2018/10/90_Casten-300x300.png" alt="" width="300" height="300" />First on the list is Sean Casten who is running to represent the 6th district of Illinois. He has undergraduate degrees in biochemistry and molecular biology and biochemistry. He also has Master's degrees in engineering management and biochemical engineering from Dartmouth College. In an email announcing his candidacy he stated, regarding the Trump Administration, "They are increasing the risk of global warming... but the truth is ignoring reality hurts so much more. They are putting millions of people's lives and health at risk with their assault on the health-care system. They are putting women's health at risk. They are putting seniors at risk with their assaults on Social Security and Medicare; the list goes on and on and on." Among his accomplishments in the clean energy field Sean Casten co-founded Recycle Energy Development LLC whose mission is to reduce greenhouse gas emissions through the recovery of waste energy...and to do so profitably. We enthusiastically endorse Sean Casten for 6th district of Illinois. <h3>Chrissy Houlahan</h3> <a href="https://www.chrissyhoulahanforcongress.com/">Support Chrissy Houlahan</a> <img class="alignright size-medium wp-image-1534" src= "https://bluestreakscience.com/wp-content/uploads/2018/10/90_Houlahan-300x300.png" alt="" width="300" height="300" />Our next endorsement goes to Chrissy Houlahan who is running to represent Pennsylvania’s 6th district in Washington. <ul> <li>She earned her engineering degree from Stanford and received her Master’s in Science in Technology and Policy from the Massachusetts Institute of Technology.</li> <li>She was a science teacher in North Philadelphia</li> </ul> And the following comes from her website: <blockquote> Climate change is real. So also is its threat to our home on this planet if we don’t manage to arrest and eventually reverse the processes that are heating our world, changing its weather, raising sea levels, accelerating desertification, and threatening traditional agriculture. </blockquote> In Congress, I will be a champion for our environment and will work to combat the threat of climate change and the assault on truth and data. Blue Streak Science is proud to support Chrissy Houlahan for Congress. If you live in or around Philadelphia then, by all means possible, get out and vote for her! We need her in Congress. <h3>Joseph Kopser</h3> <a href="https://kopserforcongress.com/">Support Joseph Kopser</a> <img class="alignright size-medium wp-image-1535" src= "https://bluestreakscience.com/wp-content/uploads/2018/10/90_Kopser-300x300.png" alt="" width="300" height="300" />Our next endorsement goes to Joseph Kopser who is seeking to represent the 21st Congressional District of Texas. Kopser founded a tech company in Austin that helped to cut carbon emissions for commuters. He was also the co-founder of the National Security Technology Accelerator which works to improve US Energy Security policy. From his website: <blockquote> Climate change is real and scientists globally accept that emission of carbon dioxide through human consumption of fossil fuels is its principal contributing cause. I support a gradually increasing fee on carbon dioxide emissions, along the lines proposed by the Brookings Institute. Consistently, studies have shown that a carbon tax is the most efficient and effective way to reduce carbon emissions. </blockquote> This is a huge race. This district was held by Republican Lamar Smith since 1987. But when Smith saw what he was facing in his changing district with Joseph Kopser he decided to not seek reelection. Lamar Smith is the head of the Republican-controlled House Science Committee. Smith is one of those anti-science types I described earlier, and and considers climate change to be a hoax. So let’s put the science back in the House Science Committee and vote for Joseph Kopser. That’s right, you guessed it. The Blue Streak Science Podcast is delighted to endorse Joseph Kopser for the 21st district of Texas. <h3>Mary Barzee Flores</h3> <a href="https://marybarzeeflores.com/">Support Mary Barzee Flores</a> Our final candidate is Mary Barzee Flores, who is running for Florida’s 25th district. This district includes much of southwest Florida, from Lake Okeechobee, Collier County and across to southwestern Miami-Dade County. <img class="alignright size-full wp-image-1536" src= "https://bluestreakscience.com/wp-content/uploads/2018/10/90_BarzeeFlores.png" alt="" width="350" height="350" />Mary majored in Music at the University of Miami, and then went on to the University of Miami Law School. After graduating law school Mary became a federal public defender, and in 2002 was elected to be a Florida Circuit Court Judge, where she served for 8 years. A few years after she was nominated by President Barack Obama for a judgeship on the U.S. District Court. Unfortunately, this was blocked by Republican Senator Marco Rubio and Mary was never even given a hearing in the Senate judiciary committee, much less an up or down vote on her nomination. Now you may be asking, okay, she sounds like an awesome person but I don’t hear a word about science in there. What’s that all about? Well, Mary and I have been friends since 1977. We met at Coral Gables High School. She is without a doubt one of the most intelligent and honest people I have had the honor to call my friend. I remember a conversation we had about how we loved science in elementary school, about how we’d come home from school excited to tell our parents this new and awesome thing we learned that day. And later when I was working at the University of Miami School of Medicine in vascular cell biology I recall her keen interest in the scientific details of what my research was all about. Mary may not be a scientist, but she understands the importance of science in making critical decisions, and in good government. This is from her website: <blockquote> South Florida is ground zero for climate change, and we must lead the way in combating it. We are already seeing the effects of stronger storms and increased flooding. By 2100, South Florida will be underwater–we cannot wait for action. As of January 2018, the Trump Administration has already overturned 33 environmental protections implemented under the Obama Administration. We must start divesting from fossil fuels and invest in green energy. America needs to rejoin the Paris Climate Accord and show global leadership in innovating for a sustainable future that incentivizes jobs in renewable energy. </blockquote> So, our final endorsement goes to Mary Barzee Flores of Florida’s 25th District. <h4>Conclusion</h4> You may not live in the districts of these science candidates, but that doesn’t mean you can’t help them get elected. All candidates need funding to get elected, especially when trying to replace well-entrenched and well-financed incumbents. I kindly ask that donate and support these worthy candidates so that you can do your part in putting science and scientific thinking in our government. <hr /> <h2>The Climate Lounge</h2> <h3>Deeper Dive Into The 1.5˚C Report</h3> <h4>Tom Di Liberto</h4> Last time, I rage screamed into your ears for an interminable amount of time about a special report released by the Intergovernmental Panel on Climate Change on the topic of the impacts of 1.5C of global warming. Well, I thought that was so nice, I’m going to talk about it twice! So break out those brown bags, because this time let’s rage scream together. But this time, the rage screaming is going to be on a more niche and pedantic topic within this voluminous new report. Yes, that’s right folks. Strap yourselves in because I’m taking you on a pathways to 1.5C˚ ride. Full of some ups, and a lot of optimistic downs. WHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE. And just like a real rollercoaster, you might throw up in the end. Pathways basically describe ways forward that society can take to keep warming to 1.5˚C by 2100. Importantly, this doesn’t mean we can’t exceed 1.5˚C for a period of time during the next century. But for these overshooters, something must be done to remove GHG from the air to bring warming back down to 1.5˚C by the end of the century. I’ll talk about four today that sort of give us a good idea of what it means to keep warming at 1.5˚C levels. And one thing to note, is that all of these require some sort of carbon dioxide removal removal technique. IE. Some technology natural or not that gets CO2 outta my air. (and into my car...for all those 80s children and Billy Ocean fans). But seriously, this is needed because not all sources of emissions will be easy to just shut off completely. And the amount of negative emission technology is incredibly important as they come with repercussions to society and wildlife themselves. Bioenergy with carbon capture and storage for instance requires lots of land to grow crops, burning them to produce energy and then capturing their co2. There are ethical AND land use questions there. Afforestation requires turning barren land into forest. If produced at scale, this increase in land use would encroach on food production and natural habitat. First, let’s start with P1. Here the world rapidly reduces fossil fuel emissions by 2020 by decreasing demand for energy by switching to more energy efficient techs and behaviors. The only negative emissions would be achieved by afforestation by turning an area roughly twice the size of Argentina into forest. P2! This one also sees a switch to better consumption patterns, better tech and managed land systems but with the addition of bioenergy and carbon capture negative emissions. This one also includes a huge amount of land turned to forest. P3 is more of a middle of the road scenario where things relating to social, economic and tech trends continue. Progress to national sustainable goals moves forward but slowly. Reduction in emissions come from changing energy production and to reductions in demand. This scenario requires a large amount of bioenergy, exceeding afforestation which means a decrease in pasture land for food production. And P4, known as a resource and energy intensive scenario where there is in increase in demand for things like air travel and meat, which require higher amounts of energy. Unlike the previous three, this scenario overshoots 1.5˚C and only returns back during a large amount of negative emissions achieved mainly through bioenergy and carbon capture. The one major downside to all this bioenergy carbon capture reliance is that at current, carbon capture and storage has only been shown at small scale at a few sites. And it has never been combined with bioenergy at scale. There is a major reliance here for technological advancement and development in the future, which, is entirely possible. But doesn’t give me the warm fuzziness. It’s a daunting task no doubt. But even if we try our hardest and don’t get to 1.5˚C. It’ll still be a lot better than the alternative. So ends this week’s class on Climate Change and our future. And this class never ends. <a href= "https://www.carbonbrief.org/in-depth-qa-ipccs-special-report-on-climate-change-at-one-point-five-c?utm_source=NEW+Weekly+Briefing&utm_campaign=86febf2fdd-Carbon_Brief_Weekly_12_10_2018&utm_medium=email&utm_term=0_b6e0a2d2ef-86febf2fdd-303572181&ct=t(Carbon_Brief_Weekly_12_10_2018)&goal=0_b6e0a2d2ef-86febf2fdd-303572181"> Carbon Brief</a> <hr /> <h2>In Closing</h2> That concludes this episode of the Blue Streak Science Podcast.

089: Rage Screaming for Science!
There were many interesting science stories this week, but none more important than the Intergovernmental Panel on Climate Change 1.5˚C Report. This may be one of the most important news stories of our lifetimes. Our government's failure to recognize its importance, and their continued contempt for inconvenient truths warranted a collective rage-scream by the Blue Streak Science Team. <h2>On This Week’s Show</h2> <ul> <li>More Nobel Prizes</li> <li>A new immune system strategy for treating cancer</li> <li>A Geyser in Yellowstone spews rubbish</li> <li>Good news for any of our listeners who happen to be bitten by a black mamba</li> <li>The Climate Lounge</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News</h2> <h4>Chris MacAlister</h4> <h3>Caltech Scientist Among Three Awarded Nobel Prize In Chemistry</h3> If you tuned in last week then you would have heard about some of this year’s Nobel Prizes, and we’re not finished with you yet! The final science award to be announced this year is the Chemistry prize; and it’s a chemistry prize with a very biological feel to it. Our good friends the Creationists often like to point out that Darwin never won a Nobel prize (largely on account of there being no Nobel prize for biology and him dying over 20 years before the first Nobels were awarded). But now, 3 people have been awarded a Nobel Prize for applied evolution. Whilst humanity have been sculpting species through artificial selection for millennia, this award for two separate projects marks a significant shift in our utilisation of it. The first was for Frances Arnold of Caltech and her efforts to create an enzyme that could break down the milk protein casein in an organic liquid. The current enzyme works in water and rather than do it herself, she decided to outsource the R&D; to bacteria. She engineered bacteria that would produce the existing enzyme for breaking down casein, but replicated this with various mutations. Once set up, she let nature take it course; selected the best performing strains and at the end of the line collected her newly forged enzyme. Clever huh? The other project is less easy to get your head around and involves phages. They went to Gregory Winter and George Smith of the universities of Cambridge and Missouri respectively. Bacteriophages are viruses that infect bacteria and Smith has used them to develop a method called phage display, where the these viruses allow you work out what genes are responsible for creating specific proteins. And this is where Winter came in. The backbone of our immune system are antibodies. These are the things that recognise infections in our bodies and kickstart the immune response. Winter used the phage expression technique, not to produce produce proteins that can be correlated to genes, but to produce antibodies. Using a similar selection techniques to Arnold he fine tuned an antibody that could bind to a target molecule. What this does it that it paves the way for the production of off-the-shelf antibodies. Miss that vaccination and caught the infection? No worries, we’ll just administer a dose immune response. <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-nobel-prize-chemistry-evolution-20181003-story.html"> LA Times</a>, <a href= "https://www.sciencenews.org/article/speeding-evolution-create-useful-proteins-wins-chemistry-nobel"> Science News</a> <h3>Immune System Reveals Potential Treatment for Cancer</h3> <h4>Sophie McManus</h4> First story covers research that concerns potential blocking of some of the complex signalling pathways present in cancer. A hallmark of cancer is overproduction of growth factors, which–you guessed it– leads to abnormal degrees of cell division. One such growth factor is epidermal growth factor, or EGF. We have current therapy options such as Erlotinib, that block EGF signalling (in some lung and pancreatic cancers), but an issue with these is that the patient can develop drug-resistant mutations. A possible new option is presented by Salvador Guardiola and colleagues - camelid‐derived single‐domain antibodies developed. Camelid is the family of animals that includes the camel (!) llama and alpaca. Who’s your favourite, Chris, JD, Tom? Anyway. This is a nice example of lateral thinking in research...it links quite nicely to my next story as well. <a href= "https://onlinelibrary.wiley.com/doi/abs/10.1002/anie.201807736">Wiley Online Library</a>, <h3>A Geyser Erupted in Yellowstone and 80 Years of Human Trash Poured Out</h3> <h4>Chris MacAlister</h4> We’ve all had those experiences, where you have a bit of a spring clean; clear out that Monica cupboard and think; huh, so that’s where that went! Well it looks like the Yellowstone National Park has been having a little spring clean of its own; specifically the Ear Spring geyser. [caption id="attachment_1518" align="alignright" width="450"]<img class="size-full wp-image-1518" src= "https://bluestreakscience.com/wp-content/uploads/2018/10/89_EarSpring.png" alt="" width="450" height="300" /> Ear Spring - Yellowstone National Park - Wyoming, USA[/caption] This geyser has just delivered its most powerful eruption in 60 years and when this happens you get more than just geothermally heated water gushing out. The most common thing to accompany it is rock, but on this occasion there has been something a little more interesting. So interesting, in fact, that curators are taking an inventory of all the things that were jettisoned. Probably the least surprising things found in this hawl are coins. Lots and lots of coins, many rusts scorched and crumbled. But there’s more. Whilst many see the Yellowstone geysers as one of nature’s marvels it appears that others see them as one of nature’s dustbins as the contents include; a large chunk of cinderblock, a broken bottle, some old aluminum cans, plastic cups and cigarette butts. Then we get to the less common waste. A rubber heel insert, which begs the question; where is the other one? Some metal warning signs, which presumably said something “Warning: geysers”, A vintage pacifier from the 1930s; now this one really fascinates me since the last big eruption was in the 1950s! Who even takes a 20 year old dummy to a national park; let alone dump it into a geyser! The final item of note was a 20 cm long drinking straw. I’m hoping that this was just another result of lazy littering and not some kind of drinking challenge gone wrong. Lighthearted approaches aside; before you go getting ideas about what could possibly go down a geyser that could give people a laugh in 60 years time, remember that there is a reason that water gets so forcibly ejaculated from these geysers; and if they become so blocked that they water can’t come straight out then that pressure will find another way to escape; in something called a hydrothermal explosion! And that's a term that doesn't sit comfortably in any sentence. ] <a href= "https://www.livescience.com/63768-yellowstone-geyser-garbage-eruption.html"> Live Science</a> <h3>Breakthrough in Treating Snake Envenomation</h3> <h4>Sophie McManus</h4> Snakes are brilliant! They can also be deadly. Two million people are bitten by snakes each year, and 100,000 of these people die, while 400,000 require amputations. Snake bites and their repercussions are mainly a problem for poorer countries. There might be some positive news, however. A paper released in the journal Nature Communications describes a promising step forward in developing human antibodies that neutralise black mamba venom. This is particularly promising given that the black mamba is a very venomous snake, highly feared in many African countries. While shy, like most snakes, if it feels threatens it will strike multiple times and inject potent neuro- and cardio-toxins. Before the development of antivenin, anyone bitten by a black mamba would die within 20 minutes. Antivenins are comprised of antibodies (proteins) that bind to the venom and neutralise further damage in the body - they do NOT reverse the effects already suffered via a bite. So today we do have antivenin, but this is derived from large domestic mammals, which are injected with small amounts of the venom in question. The domestic host then produces antibodies against the venom which are harvested from the blood and purified for use in clinic. This is not ideal for a number of reasons. People receiving antivenin can suffer from side-effects (such as serum sickness). However, when bitten by a highly venomous snake, you don’t get a lot of options. The “proof of concept” research described in Nature Communications identified key components, including dendrotoxins, in the black mamba’s venom which contribute to venom toxicity. Human antibodies were generated to these dendrotoxins using IONTAS Phage Display Technology and cocktails of IgG-formatted human antibodies were then shown to protect mice from dendrotoxin-mediated neurotoxicity in vivo. <a href= "https://www.technologynetworks.com/cancer-research/news/black-mamba-snake-venom-neutralized-with-human-antibodies-310282"> Technology Networks</a>, <a href= "https://www.nature.com/articles/s41467-018-06086-4">Nature Communication</a> <hr /> <h2>The Climate Lounge</h2> <h3>IPCC 1.5˚C report</h3> <h4>Tom Di Liberto</h4> The Lounge was buzzing over the last couple of days. A large swarm of bees got in somehow. But once that was taken care of, all of us Climate Loungers dove head first into the latest report released by the Intergovernmental Panel on Climate Change or IPCC on the feasibility of keeping temperature rise to only 1.5˚C and the impacts that would global temperature rise would on the planet. You know how I’ve been doing some fun, less depressing climate stories in the lounge recently. This is not that. First, the stats, this report was edited by 91 scientists from 40 countries who looked at more than 6000 scientific studies, white papers and policy studies. Note I didn't say blog posts, or media diatribes, or rantings of the unqualified. I said scientific studies. Specifically, 1.5˚C (2.7˚F) was looked at as a threshold over the more generally considered 2C due to requests from the heads of small island nations over fears of sea level rise wiping out their countries. If you've heard of the 2C threshold, or anything threshold, it’s important to know that threshold is in quotations, bunny ears. There is no on switch that goes off once you pass that number. Climate change impacts are a spectrum and don't magically get turned on all at once but grow gradually. And recent research has suggested that they are getting worse faster. We are expected to reach 1.5˚C by 2030 to 2052, And at that global temperature rise many island nations will become uninhabitable due to sea level rise, 70-90% of the worlds coral are dead, Wildfires will increase, poverty will increase. It just sucks. Thats my scientific bottom line. 1.5˚C sucks. Especially for the, you guessed it. The Poor. What will it take to get there? A reduction in GHG by 45% from 2010 levels (that’s 58% by 2015 levels) by 2030 and100% by 2050. By 2050, coal has to go from almost 40% to 1-7%. Renewable energy will need to increase from 20% to two thirds during the same time. In response, the world coal association said..wait, who gives a shit what they said. Moving on. In sum, let me quote Gain Schmidt of NASA’s Goddard Institute of Space Studies about this report, “The key thing to remember is that it’s clear that the best time to reduce emissions was 25 years ago. But the second best to reduce emissions is right now.” This transition would involve an investment of $2.4 trillion annually from 2016-2035. Which is a ton more than we currently are spending. But, on the flip side, this report attempted to put a price tag on the effects of climate change, which were $54 trillion from 1.5˚C to $69 trillion from 2˚C and increasing ever after. But even with that said 1.5˚C is still better than 2˚C. It could reduce the number of people exposed to climate related risk and susceptible to poverty by up to several hundred million by 2050, which is better than 3˚C which is better than 4˚C, which is better than [cue clock music], which is better than… you get the point. But in case you don't, there will ALWAYS be a need to fight climate change and stop our emissions of greenhouse gases, regardless of how much warming happens. So let's have none of this, it's too late business. That’s nonsense. It’d be like taking a test and not knowing the first question, so instead of taking the rest of the test, you just give up and hand it in. A 90% is a lot better than a zero folks. In conclusion, We are already halfway to 1.5˚C. And we only have roughly 20 years to when we might reach 1.5˚C. That may seem like a lot of time. But it’s not. 20 years ago Saving Private Ryan was released. If that doesn’t seem like a long time, than 2040 isn’t a long time away either. I’m angry. I’m p*ssed. And you should be too. I’m angry at our political leaders. I’m angry at the general populace for not caring. I’m angry that I’ve been hearing the same damn thing, roughly, from scientists for decades and yet here we are. But anger isn’t going to do anything. If you’re angry, Vote! Vote for people who don’t have their heads in the sand and actually care about our future. If you’re angry, volunteer! Spend your time with any number of organizations helping those who can’t prepare, adapt. If you're angry, GREAT! Turn that anger into the courage to speak up to anyone who will listen.

088: Nobel Prize Week Begins!
Last week it was the fun stuff, but this week it's that most serious of awards ceremonies, The Nobel Prize Awards. Sophie gives us the low-down on this year's winner in the category of Medicine and Physiology. JD breaks in with a newsflash, as one does, with Nobel Prize in Physics. <h2>On This Week’s Show</h2> <ul> <li>Nobel Prize Week</li> <li>Scientists De-Code How the Brain Processes Speech</li> <li>Hayabusa Rovers Send New Pics of Comet</li> <li>CDC: 80,000 Died From Flu In 2017</li> <li>The Climate Lounge</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News with Sophie McManus and Chris MacAlister</h2> <h3>Cancer Immunologists Win Nobel Prize in Medicine</h3> <h4>Sophie McManus</h4> The Ig Nobels took place recently, but now it’s time for the Nobels. The winners for the Nobel Prize in medicine are two scientists who have pioneered immunotherapy for cancer. Their names are James Allison and Tasuku Honjo. They separately discovered proteins that act as a brake on the immune system. They later found that releasing these brakes would allow the immune system to attack cancer cells. Drugs called checkpoint inhibitors have resulted from this discovery and immunotherapy is considered a hugely promising way to treat cancer. Honjo was inspired to cure cancer back in the 1960s after a classmate died from gastric cancer. By the 90s, he had discovered a protein with the name PD1. This protein is a checkpoint in the immune system, or a ‘brake’ - when PD1 is disabled then the immune system goes into overdrive. It was discovered also that some cancers can produce PD1 interactors which enable them to dodge the immune system. Hence BLOCKING PD1 can give the immune system a boost - to tackle abherrant cancer cells. Today, PD-1 inhibitors such as nivolumab and pembrolizumab have been found to shrink tumours far more effectively than chemo- and radiotherapy and crucially also have much milder side effects. Working independently of Honjo, James Allison, then at the University of California, Berkeley, was one of several scientists who studied a ‘checkpoint’ protein, CTLA-4, that acts as a brake on immune cells called T cells. In 1997, Allison and his colleagues engineered an antibody that could bind to CTLA-4, removing the brakes on T-cell activity and unleashing them to attack cancer cells in mice. A clinical study in 2010 found that the antibody had a striking effect on people with advanced melanoma, a form of skin cancer. Allison was woken at 5.30 by his son delivering the good news and by 6.30 his group had turned up with champagne for an impromptu party - before the Committee had even got through to him! Thanks to Honjo and Allison immunotherapy is regarded as a strong pillar in the work to treat cancer. <h4>Newsflash!</h4> The Nobel Prize in Physics was just awarded this morning at the time of this podcast recording on Tuesday. It was awarded to three scientists for their work in using super intense lasers to capture incredibly fast processes, and to accurately manipulate objects as small as cells and viruses . The scientists are Donna Strickland of the University of Waterloo in Ontario; Gerard Mourou, a former colleague of Strickland who is currently at Ecole Polytechnique in Paris, and Arthur Ashkin of Bell Laboratories in New Jersey. Together Strickland and Mourou developed techniques to create the highest frequency, and most intense light pulses ever. These light pulses are now being used in many fields of science to probe physical processes once considered to be instantaneous. In separate research Arthur Ashkin developed “optical tweezers” using lasers. These beams of light are used to manipulate and move objects as small as viruses. One more thing; Donna Strickland is the first woman recipient of the Physics Prize in 55 years. I look forward to the day when I don’t have to make mention of such facts...the day when there’s gender equality across all the sciences. <a href= "https://www.europeanscientist.com/en/public-health/new-immunotherapy-suppresses-hiv-for-months-and-could-simplify-treatment/"> European Scientist</a>, <a href= "https://www.nature.com/articles/d41586-018-06773-8">Nature</a> <a href= "https://www.newscientist.com/article/2181067-cancer-immune-therapy-recognised-with-nobel-prize-for-medicine/"> New Scientist</a>, <a href= "https://www.nature.com/articles/d41586-018-06751-0">Nature</a> <h3>Scientists De-Code How the Brain Processes Speech</h3> <h4>Chris MacAlister</h4> It feels like we have stories every week that just leave you bewildered about what humanity can achieve and for me, this is another one of those stories. Whilst the human brain remains one of the great enigmas of nature, we have moved yet another step closer to getting a handle on what is going on in there. Brain scanning technologies have allowed us to map our brains and link certain functions, such as movements, senses and emotions to particular parts of the brain and over time the precision of these scans has improved. One of the most impressive applications of this understanding has been the production of prosthetics that respond directly to brain signals. So it is now possible for people who have lost limbs to control their prosthetic with the power of their mind alone, not entirely unlike how they would have controlled their original limb. This most recent study by Northwestern Medicine and the Weinberg College of Arts and Sciences has looked at language and how the brain encodes that information. This study has precisely mapped how the brain works when we speak. Not only has it mapped the physical motions made by our mouths and tongues; they’ve be been able to correlate this with another part of the brain that generates the cues for the movements. So just to be clear, they have directly witnessed the brain speaking; the very intent of language, clear and unflustered by tongue-ties or twisters. So to feed back to what I said earlier. The plan now is generate an algorithm that can translate these brain signals directly into speech. If they can manage this then they will have created a neurally controlled prosthetic voice box. A machine like this could literally speak your mind for you. And whilst this may sound like a pretty cool party trick, imagine how much more important it would have been for someone like Stephen Hawking. Few people appreciate just how long it took for Hawking to form a sentence using the technology that was available to him. Imagine the difference it would have made for him to just think those words for them to be sent to his computer. And this is what really inspires me about stories like these. The time, effort and money that is put into helping other people; not just ourselves. No sooner have we discovered something remarkable and new about the brain and the first question that the people involved ask themselves is “how do we use this to help people?” <a href= "https://news.northwestern.edu/stories/2018/september/scientists-unlock-secret-of-how-the-brain-encodes-speech-2/"> Northwestern University</a>, <a href= "http://www.xinhuanet.com/english/2018-09/29/c_137499947.htm">Xinhuanet</a>, <a href= "http://www.jneurosci.org/content/early/2018/09/26/JNEUROSCI.1206-18.2018"> Journal of Neuroscience (abstract)</a> <h3>Hayabusa 2 Rovers Send New Images Ryugu Surface</h3> <h4>Sophie McManus</h4> I am going to jump to talking about hopping robots on a space rock! (agh, worst attempt at a pun ever). So, the Japanese space agency (JAXA) sent spacecraft (Hayabusa II) over to an asteroid called Ryugu. The journey - all 319 million km of it - took three and a half years and the spacecraft finally arrived in June. For a couple of months, Hayabusa took images from above Ryugu, before descending 60 metres above it to deploy two rovers on the 21st September. Their mission was to explore Ryugu’s rocky surface. This is the first time rovers have successfully landed and sent back videos of an asteroid’s surface. What’s extra special about these rovers is that they hop, rather than travel on wheels. There is low gravity on the asteroid surfaces, so hopping takes them pretty far. (As a side note, it’s known that our most famous Earth-bound hoppers, kangaroos, are amongst the most efficient travellers on Earth - I don’t know if Hayabusa engineers were inspired by marsupials in their rover design though). There were concerns that the rocky surface of Ryugu might hamper the rovers’ transport, but it seems they are working well despite the challenge - they can hop up to 15 metres, staying airbourne for up to 15 minutes at a time! It is hoped that studying the surface of Ryugu might teach us more about the formation of our own planet. Asteroids such as Ryugu are made from the cloud of gas and dust debris (solar nebula) that arose from the formation of the Sun. A quote from Helena Bates, a PhD student at London’s Natural History Museum who studies asteroid formation ‘[Asteroids] are little snapshots of what the solar nebula looked like before there were planets'. The two rovers will be joined at the beginning of October by a third lander called MASCOT to measure the structure of the minerals, thermal behaviour and magnetic properties of the asteroid. Towards the end of the month, Hayabusa2 itself will descend and touch Ryugu to pick up its first sample. “The image taken by MINERVA-II1 during a hop allowed me to relax as a dream of many years came true,” said Hayabusa 2 spokesperson Takashi Kubota.

The first one is somewhat sombre as last year has officially been a stinker for influenza infections with an estimated 80,000 deaths in the US. As if that wasn’t shocking enough, there were also some 900,000 hospitalisations due to flu. It has been the worst season for flu in 11 years. The big problem with flu is it’s compulsion to change and this makes the flu a bit of a lottery every year, the lottery being how severe the symptoms of your flu will be. Which brings us on to the second story which is the discovery of what makes some flus so dangerous. Really, it makes no sense for viruses to be fatal. Unlike bacteria they are 100% reliant on their host for survival, so killing your host makes bad news for you. Now, this new study, looking at the great flu pandemic of 1918, points to these strains of flu as being bad viruses. Much viral variation comes from mutation and most mutations are not beneficial. What this means that you end up with some strains of flu that struggle to reproduce themselves. This struggle creates a by-product which is a mini-RNA molecule. Whilst viruses go around trying not to be spotted, this RNA byproduct is actually very conspicuous and your immune system goes to town on it. Since flu infects the respiratory tract, this can lead to people drowning in their own immune response. The thing that makes this the good news story of the two is that now we understanding this mechanism we can now start looking for treatments that could save lives.] <a href= "https://www.sciencenews.org/blog/science-ticker/cdc-says-80000-people-died-flu-last-year"> Science News</a> <hr /> <h2>The Climate Lounge</h2> <h3>Game Night</h3> <h4>Tom Di Liberto</h4> It may be stormy outside (and I mean that in any literal or figurative sense you’d like. Good lord the news has been horrid. I believe Dr. Ford.), but in the climate lounge, it’s time for GAME NIGHT! With a twist. So leave your settlers at home. Don’t even bother opening Carcassonne. And you’ll have to prove how “funny” you are at Cards against Humanity at a later date because today, we are talking Climate games. First, let’s talk about a game for all of us! Regardless of age. The only requirement is a desire to be incredibly nerdy. Scientists with the nonprofit Climate Interactive have developed a role playing game based upon World Climate Negotiations. Players have to save the world from climate change as participants to a United Nations conference. Every single decision made by the players is then fed into a climate policy model called CROADS. It takes the policy decisions and uses current climate science to shows the impact on the global climate system. That includes economic prosperity, health, safety from natural disasters. You win if you save the world. That’s a pretty good thing to try and win at. This game is supposed to be run with 8 to 50 people but has been scaled for up to 500 people. And has a game time of 2-3 hours (although a truncated version lasts 45 minutes.) The scientists survey over 2000 players before and after the game and found that the knowledge of climate change causes and impacts increased, as even more importantly the players sense of urgency increased.81% said their desire to learn and do more about climate change had increased. Now if you follow the social science research on climate change, you’d know that one of the hardest things to do is get people who otherwise understand and accept climate change to get up and actually do something about it. To have that sense of urgency. With all that goes on in the short term in a person’s life, it’s hard for a long-term problem like climate change to crack that top 10. But this game seemed to do that. Which is good, cause, um guys, climate change is like an urgent problem. Ok, one more quick climate game to round out a fun evening of playing in the lounge. And this one is particularly good because it made me feel like ancient. Climate FORTNITE! You may know the online playing battle royale game climate fortnite. Perhaps, you have kids who play it. Perhaps you play it. Either way, you’ve heard of it. For those who haven’t, it’s sorta the current hotness when it comes to the pop culture zeitgeist. People by the 10s of thousands watch other people play this game at places like Twitch (for livestreaming video games) and on youtube. Basically, numbers that you’d wish would exist for climate science based youtube videos but instead go to vids of people doing epic kills. (God I’m old). Anyways, some climate scientist thought, Hey, let’s take advantage of that and do live-streams and videos of us playing fortnite but also talking climate change. And that’s what they’ve done. It started with a MIT graduate student named Henri Drake and has included a bevy of climate scientists including folks like Andrew Dessler who plays with his kids (his kids are much much much better than he is). So while their squad works to kill ‘em all, the scientists end up talking about how climate models work, the latest arctic research or how ice ages came about. It’s an incredibly creative way to do climate communication so check them out. They play every Tuesday 830-1030pm Eastern and you can check out more updates from them at the twitter and Twitch handle ClimateFortnite. <a href= "http://www.sciencemag.org/news/2018/09/scientists-hope-spark-action-climate-change-turning-it-game?rss=1"> Climate game</a>, <a href= "https://earther.gizmodo.com/these-scientists-formed-a-fornite-squad-to-teach-player-1828886797"> fortnite</a> <hr /> <h2>Pub Quiz</h2> <ol> <li>A very rare animal was photographed for the first time ever in Semuliki National Park in Uganda.

087: Japan Threatens To Resume Industrial-scale Whale Slaughter
Science marches forward, but sometimes nations march backward. This is certainly true in recent years with my own country, and we're not alone in our reversion to a lesser form of ourselves. The government of Japan is throwing an international temper tantrum because most of the rest of the world don't want to go back to the awful days of wanton and senseless slaughter of whales for commercial purposes. Yes, we're judging. And the verdict speaks poorly of this great nation. Japan can, and must do better. <h2>On This Week’s Show</h2> <ul> <li>Science News of the Week</li> <li>The Climate Lounge</li> <li>A****** of the Month</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News with Dr. Amrita Sule and Chris MacAlister</h2> <h3>Skeletal Stem Cells Found In Humans</h3> <h4>Amrita Sule</h4> Today’s stem cell story is super exciting because it is the very first time researchers have identified these very specific stem cells in humans, which differentiate into the skeletal cells. Stem cells have been studied rigorously for their ability to self renew and differentiate into more specialized cells. Stem cells, however, differ in their ability as to what they can do and what they cannot. There are different kinds of stem cells in our body, formed at different times present in different places of the body. It has not been an easy journey to pin down a stem cell type that forms the skeletal tissue like bone and cartilage. Skeletal stem cells were first identified in a mouse model called the rainbow mice. Well, what is a rainbow mouse? In these mice each type of stem cell was color-coded and its differentiation into different organs or tissues was tracked. How cool is that! However, it is not possible to do this in humans (no rainbow humans). So instead, the researchers looked at cells which had gene signatures similar to that found in the mice skeletal cells. They worked with fetal bones from the fetuses that were aborted or did not survive. They isolated stem cells from the growth plate which is a region in the bone where new cells are made. These cells when grown in lab dishes formed new bone and cartilage. Voila!!! We have a bone in a dish! But can these cells form bones or cartilage if we inject them in body? To test that these stem cells were transplanted under the outer kidney layer. And yes, they grew into bones and cartilage. This discovery carried out by Longekar group in Stanford and was published in the journal Cell this past week. These scientists were able to create a family tree for the skeletal stem cells. With skeletal stem cells being at the apex followed by pre BCSP (bone, cartilage stromal progenitor) followed by the BCSP, which then gives rise to the bone, cartilage, and stromal cells, respectively. This discovery has great implications in diseases like osteoporosis as well as any kind of bone injury and change the field of orthopedics. <a href= "https://www.sciencemag.org/news/2018/09/skeletal-stem-cells-found-humans-first-time-promising-new-treatments-fractures-and?rss=1"> Science</a> <h3>Dickinsonia, The Animal Kingdom’s Oldest Member</h3> <h4>Chris MacAlister </h4> Whack on your lipstick, pucker up and lay a wet one on your fridge, a window, a family heirloom or even a total stranger. It doesn’t really matter, provided that you leave a mark. Because if you think about what that distinctive lip mark looks like then you’re also thinking what the fossil remains of a creature called Dickinsonia looked like. Although, at up to a meter long, not even Mick Jagger would be able to make an accurate recreation of one this way. We have a rich a varied fossil record available to us today but it’s a simple fact is that, the further back in time you go the hazier things get, and this is where Dickinsonia may be of some assistance. Even though they they lived around 550 million years ago they are now providing some ammunition for a really bad low budget horror flick as in 2016 a naturally mummified Dickinsonia was discovered. Paleontologists are known to get very excited about fossils, but there’s a whole other level of excitement reserved for mummies. Because whilst bones and hard bits of creatures can tell you a lot, soft, squishy, gooey stuff can tell you so much more and in within mummification, this stuff fossilizes too. For example; within the gooey stuff of this Dickinsonia was a fossil of colesterol. This may not sound to exciting on the face of things but let me paint the scene because, to be perfectly honest, our knowledge of life at this point of history is pretty lousy. This fossil is from a time before the period known as the Cambrian explosion, where practically every arrangement of life that is familiar to us today first developed. This means that we have virtually no frame of reference for everything existing before and our knowledge is so scant we are struggling to classify things at the kingdom level. The kingdom level! That means that we don’t know whether Dickinsonia was an animal, a fungus or something completely different. But colesterol? Colesterol has only ever been seen within animals, which is the best clue the we have yet as to what is creature actually was.] <a href= "https://www.scientificamerican.com/article/say-hello-to-dickinsonia-the-animal-kingdoms-newest-and-oldest-member/"> Scientific American</a>, <a href= "http://science.sciencemag.org/content/361/6408/1246">Science</a> <h3>This Research Group Seeks To Expose Weaknesses In Science</h3> <h4>Amrita Sule</h4> I think we all can agree when I say that one way forward to scientific progress is “transparency”. However, there is an emergent trend where we see falsified data or even poor-quality data which has led to numerable retractions. Several of these retractions were based on the results not being reproducible. This reproducibility crisis is prevalent in many fields including basic and clinical biology and often the result of poorly designed experiments if studies just attain highest statistical significance. Academicians live by the three words, “publish or perish”, and this is definitely one of the reasons why poor quality studies get published. The problem being identified, the question is how can we circumvent this? Two psychology researchers Marcel van Assen, Tilburg University and Jelte Wicherts assistant professor at the University of Amsterdam identified this issue in their field when a prominent psychologist Diederik Stapel from Tilburg University confessed of fabricating and faking data for over 15 years. This was big. But the bigger question was how did everyone miss this? And this is just one person. More importantly how do we fix this? These two psychologists pioneered the formation of a group of meta researchers which basically will study how scientists operate. With a grant from the European Research Council they are trying to build software which will allow researchers to analyze their data and reduce the risk of bias at the same time. There exists counterparts of such groups, e.g., the Center For Open Science in Charlottesville, Virginia, as well as the Society For The Improvement Of Psychological Sciences. One of their projects is call Statcheck. Statcheck can scan papers for statistical significance. Think of it like a mathematical spell check. This algorithm identified that 1 in 8 papers out of around 30,000 it scanned (1985-2013) have errors with regards to statistical significance. And there is a chance that many of these are accidental errors, but they still get published unchecked. The group wants to study the data published in 200 psychology studies and analyze it in different ways to check if there were any biases when the study was conducted. But the hindrance here is that not all researchers are OK with sharing data. And that will make such a study difficult. Many journals now across the different fields are making it mandatory to share data and the number of open-data publications is going higher every day. This brings me back to the point of transparency I started with. <a href= "https://www.sciencemag.org/news/2018/09/research-group-seeks-expose-weaknesses-science-and-they-ll-step-some-toes-if-they-have?rss=1"> Science</a> <h3>TESS Spacecraft Has Discovered Its First Alien Worlds</h3> <h4>Chris MacAlister </h4> This story is making me a little nostalgic. I’ve been appearing on this podcast for about about six months now and one of the stories from one of my very early episodes was about the launch of TESS. NASA’s Transiting Exoplanet Survey Satellite was sent to replace the Kepler space telescope as our number one exoplanet spotter and it’s already logged its first find. The new exoplanet is about 60 light years away, orbiting a star called Pi Mensae. People often wonder how planets can even be detected around stars many light years away, and there are several methods which can be employed to work this out such as wobbles in the star’s position as the gravity of its planets pull back or dips in the star’s luminosity as a planet passes in front of it. But what gets me is level of detail that can be calculated from this data. According to the data, this new planet, Pi Mensae C is twice the size of Earth, it orbits its sun every 6.27 days (which would make it a great place to visit if you love New Year) and is probably gaseous, like a mini Neptune. I don’t know about you but that seem ridiculously specific, especially when you consider that these deductions had to take into account the effects of Pi Mensae B. This is the other planet already discovered around this star and one of the biggest planets ever discovered anywhere, 10 times bigger than Jupiter! The team at NASA thought that it was too good to be true, to find this at pretty much the first thing that the new telescope looked at. But whilst we’re at it; they’ve actually found another one as well! Forty-nine light years away we now have LHS 3488b, which is 1.3 times the size of Earth and an even better place for fans of New Year as it’s solar orbit lasts only 11 minutes. Those would be some seriously hot parties and I mean literally because surface temperatures there are over 500oC! So to all of you LHSians out there, Happy New Year! <a href= "https://www.newscientist.com/article/2180324-nasas-new-exoplanet-hunter-has-spotted-its-first-alien-worlds/"> New Scientist</a> <hr /> <h2>The Climate Lounge</h2> <h3>Life on an Arctic Survey</h3> <h4>Tom Di Liberto</h4> Just right off the bat, let me say that anyone trying to pretend that Maria and the poor relief effort afterwards didn’t kill thousands of people is a dumb***. Moving on. This week in the climate lounge, I’m taking you someplace really really cool. So cool, it’s cold. How cold is it? Cold enough to serve as the desolate remote outpost for research surveys into the Arctic. I’m talking about Station Nord, a itty bitty military outpost of the Danish military in northeastern Greenland 575 miles from the geographic North pole. Like imagine a map of Greenland. Imagine a place really far north of on that map. Great. No go farther north. That’s where Station Nord is. And that’s where science happens, so lets learn how. Now Global warming has so many canaries in a coal mine that that damn coal mine is basically a bird exhibit at a zoo. But a number of those canaries are wearing their best down jackets high in the Arctic. #1 among them is the state of Arctic sea ice. Arctic sea ice extent is rapidly dwindling over the last 30 years (13% by decade), no doubt due to the fast rising global temperatures which are amplified in the Arctic. But another thing that is incredibly important is sea ice volume or how thick the ice is. Thinner ice breaks up easier. And knowing the location of the thicker ice can let scientists know if the winds are blowing old thick ice out into the open ocean to melt or not. But measuring thickness from satellites has its flaws, especially in the summer months when ice is melting. There is a need for on location monitoring. And that’s where Station Nord fits in. Since 2011, scientists from the Alfred Wegener institute have been using Station Nord and placing sensors on a souped-up DC3 airplane and flying over the arctic measuring ice thickness Station Nord is staffed by six soldiers on two year tours. From October through March they are alone except for the companionship of two dogs who help alert everyone to the presence of polar bears. Scientists begin to show up in late Winter into early Spring. The Wegener institute scientists (a total of nine people) showed up in late July and August. But a lot of their time was spent waiting for the right weather window to fly their planes. In total they made only nine flights which was pretty good actually. But means there is a lot of down times. So what do you do in the middle of nowhere? What happens in station Nord does not stay there because that’s a horrible way of thinking about anything and no location, however remote should allow for things to occur that never get out. There are weird rituals. Every Saturday for instance, everyone has to wear a tie when going to dinner. They also host an Arctic/Greenland style medieval games complete with jousting while riding in the bucket of carrier bike while people scream and blow horns in their ears. Oh and somehow they have a pig roast once a year. They actually transport a whole hog to the far north. In between doing science of course. So I guess it could be worse but still this is a harsh harsh environment that scientists put themselves in for weeks or months at a time to tell us the latest news from the arctic. Away from their families, away from their friends, away from civilization. But sometimes, things are worth that struggle. At least they aren’t the military folks stuck there for 2 years! <a href= "https://www.nytimes.com/2018/09/21/climate/greenland-arctic-ice.html"> NY Times</a> <hr /> <h2>A****** of the Month</h2> Dateline - FLORIANOPOLIS, BRAZIL – Japan’s attempt to resume unabated commercial whale hunting was rejected earlier this month by the International Whaling Commission (IWC). Masaaki Taniai, vice minister for fisheries in Japan, said he “regretted” the vote’s outcome Friday and threatened Japan’s withdrawal from the IWC. Anti-whaling nations led by Australia, the European Union and the United States defeated Japan’s “Way Forward” proposal in a 41-27 vote. The IWC was set up in 1946 to conserve and manage the world’s whale and dolphin populations. They began a moratorium on commercial whale killing in 1986 after some species, such as humpbacked whales had been slaughtered to near extinction. Currently Japan ostensibly observes the moratorium but takes advantage of a loophole to kill hundreds of whales every year for “scientific purposes”, and then that whale meat ends up on dinner plates. So, the IWC adopted Brazil’s “Florianopolis Declaration,” which envisions whale protection in perpetuity...which I’m sure pisses off those who want to return to commercial whale slaughter. The “Florianopolis Declaration,” is currently non-binding, but anti-whaling nations herald it as an important indicator of the IWC’s future direction. Kitty Block, head of Humane Society International, said “the IWC’s moral compass” had led it to reject Japan’s proposal. “It’s clear from exchanges this week that those countries here fighting for the protection of whales are not prepared to have the IWC’s progressive conservation agenda held hostage to Japan’s unreasonable whaling demands.” So, the government of Japan, for your petulant response, and threatening to leave the IWC and to resume the slaughter of whales...you are the Blue Streak Science A****** of the Month. <hr /> <h2>Pub Quiz</h2> <ol> <li>How long can a sperm whale stay underwater on one breath?</li> <li>Give me one good reason that scientists believe whales were once land-based animals?</li> <li>What is the name given to a method employed by many whales to find prey and locate obstacles in the water using sound waves?</li> <li>How are whales able to eat while submerged without drowning?</li> <li>When a person observes a whale spout, what can they tell about the whale that created it?</li> <li>What is a baleen?</li> <li>What species of whale has the nickname “sulfur bottom”?</li> </ol> <hr /> <h2>In Next Week’s Episode</h2> In next week’s episode we’ll be talking about the one year anniversary of the wildfires in northern California.

086: Time And Relative Dimension In Space
A slight diversion from the usual format today. But hey, do we know how to turn out a science podcast or what? Chris and JD talked about everything from cigarette smoking kids to self-administered colonoscopies. And of course, this episode was custom-made for all the Whovians out there. You know WHO you are. <h2>On This Week’s Show</h2> <ul> <li>More kids in Europe are starting to smoke tobacco</li> <li>We have a heaping helping of Nuclear Pasta</li> <li>California Announces that it’s gonna launch its own damn satellite</li> <li>The Ig Nobel Prize winners for 2018</li> <li>Doctor Who!</li> <li>The Pub Quiz</li> </ul> <hr /> <h2>Science News with Chris MacAlister and JD Goodwin</h2> <h3>More Children In Europe Have Started Smoking</h3> <h4>Chris MacAlister</h4> Has anyone got a light? The question’s rhetorical since I am a part of a statistical majority of European non-smokers. This is largely a good news story as the number of people who are taking up smoking in Europe has been greatly declining since 1980 onwards but, you know, there are some people out there who can’t just let good news be good news. People who think every silver lining has a cloud; and on this occasion these people have found that smoking levels have actually gone up in one age group: 11 to 15 year olds. The idea of 11 to 15 years olds smoking makes my head spin even before we start talking about an increase and any signal like this in the youngest bracket of our population should set alarm bells ringing. Is this indicative of an emerging cultural shift? I wouldn’t be getting too concerned just yet. The number of cases that we are looking at small and there are some massive unknowns associated with this data. For example, the study does not look at how frequently people smoke, it does not take into account whether these kids regular smokers or are just experimenting, hell, it doesn’t even know whether these kids are smoking conventional or e-cigarettes! However, this did make me think of one cultural risk that could surround this issue. Such great efforts have been made to stop glamorisation of smoking and this, along with other strategies have clearly been effective at reducing smoking levels. But most smokers do not provide glamour. Your stereotypical image of a smoker is probably not a suave sophisticated figure in lounge jacket, it’s probably something a bit less healthy and possibly more sleazy and definitely more smelly. With these images fading too we are losing both the carrot and the stick of influence. This potentially leaves you with what I like to call the Google+ school of promotion, which says that if no old people are doing it then just maybe young people will think it is cool. It hasn’t worked for Google and hopefully it won’t work for smoking either. But the older generation is not going out of its way to stop you from using Google; and there is nothing more tempting to a teenager than forbidden fruits; so the story may well not be over yet on this one... <a href= "http://sciencenordic.com/more-children-europe-have-started-smoking"> ScienceNordic</a> <h3>Nuclear Pasta In Neutron Stars</h3> <h4>JD Goodwin</h4> This is from an article in New Scientist, and it’s about pasta! But this is nuclear pasta, and it’s my guess that it would fully absorb any sauce you throw at it In report in Physical Review Letters this nuclear pasta is said to be really strong stuff. Breaking it would require 10 billion times the force needed to break steel. This pasta is found in neutron stars. Neutron stars form when a dying star explodes, leaving behind a neutron-rich remnant that is squished to extreme pressures by powerful gravitational forces, resulting in materials with strange properties. A kilometer or so below the surface of one of these stars atomic nuclei are packed together so close that they merge into clumps of nuclear matter, a dense mixture of neutrons and protons. These theoretical clumps are thought to be shaped like blobs, tubes or sheets, and are named after types of pasta such as gnocchi, spaghetti and lasagna. Even deeper in the neutron star, the nuclear matter fully takes over. The burnt-out star’s entire core is nuclear matter, like one giant atomic nucleus. This nuclear pasta is incredibly dense, about 100 trillion times the density of water. Researchers used computer simulations to stretch nuclear lasagna sheets and explore how the material responded. Neutron stars tend to spin very rapidly, and, as a result, might emit ripples in spacetime called gravitational waves, which scientists could detect at facilities like the Advanced Laser Interferometer Gravitational-wave Observatory, or LIGO. But the spacetime ripples will occur only if a neutron star’s crust is lumpy — meaning that it has “mountains,” or mounds of dense material either on the surface or within the crust. A stiffer, stronger crust would support larger mountains, which could produce more powerful gravitational waves. Due to the intense gravity of neutron stars, their mountains would be a far cry from Mount Everest, rising centimeters tall, not kilometers. Previously, scientists didn’t know how large a mountain nuclear pasta could support. The results of the simulations suggest that nuclear pasta could support mountains tens of centimeters tall — big enough that LIGO could spot neutron stars’ gravitational waves. If LIGO caught such signals, scientists could estimate the mountains’ size, and confirm that neutron stars have amazingly strong materials in their crusts. <a href= "https://www.sciencenews.org/article/nuclear-pasta-neutron-stars-may-be-strongest-material-universe"> New Scientist</a> <h3>California To Launch Its Own Damn Satellite</h3> <h4>Chris MacAlister</h4> We go from looking to space for some super strong stuff to looking to space for something much less fragile, our climate. Yes, in the sad absence of Tom Di Liberto this week it falls to me to delivery your regular climate update. We’ve discussed the feasibility of California being its own nation a few times on this show, albeit from a purely theoretical position; but it seems that Jerry Brown may be taking things a step further. The Governor of California has announced something not entirely unlike a Californian space programme. Whilst there are only about 13 space agencies in the world (Europe has even had to club together to make theirs). This wouldn’t be too much of a stretch for the state whose economy would be the 5th largest in the world if it were a sovereign nation. The mission that Gov. Brown has announced is a satellite to monitor carbon levels in the atmosphere. Whilst NASA is already doing this, it may come as no surprise that the Trump administration are doing their best to demobilise this operation. Whist this news is quite remarkable itself, the thing that I love the most about it is how it came to be. In the wake of the withdrawal from Paris climate accord and the bloody disregard that Trump and his lackeys clearly have for this one sanctuary for life in an otherwise infinite universe of death; thousands of mayors, regional leaders and corporate executives have come together in San Francisco for a Global Climate Action Summit. This was basically a forum for every American with a position of influence and a shred of moral integrity to come together and say: Balls to you Donald; not on my flaming watch! I should just clarify that this really isn’t a Californian space programme. The satellites will be purchased from a company called Planet Labs. This firm was started by 3 ex-NASA employees who have developed a fleet of micro-satellites. But the important point here is that by going private, California can sidestep the influence that the state has; a luxury that is not afforded to state funded organisations such as NASA.] <a href= "https://www.sfchronicle.com/science/article/Brown-announces-California-plan-to-launch-13230706.php"> San Francisco Chronicle</a> <h3>2018 Ig Nobel Prizes</h3> <h4>JD Goodwin</h4> Every year, this time of year, at Harvard University in Cambridge, Massachusetts a special ceremony is held. And last week it was once again time for the Ig Nobel Prizes, put on by the esteemed journal The Annals of Improbable Research. So let’s get right to it: The Ig Nobel Prize in Medicine was awarded to researchers who discovered that riding roller coasters may be an effective method for dislodging kidney stones. The inspiration behind the roller-coaster research began several years ago when one of Prof David Wartinger's patients at Michigan State University's College of Osteopathic Medicine returned from a holiday trip to Walt Disney World in Florida. The patient reported that one of his kidney stones became dislodged after a ride on the Big Thunder Mountain ride. Wondering whether it was caused by the ride or a coincidence, the patient went on the ride several more times and each time a stone popped out. Intrigued by the story, Dr. Wartinger built a silicone model of his patient's renal system, including artificial kidney stones, and took it with him on numerous rides. He discovered that Big Thunder Mountain was indeed effective - more so than other rides such as Space Mountain Dr. Wartinger concluded that this was because Big Thunder Mountain involves more up and down and side to side movements that "rattle" the rider. Japanese gastroenterologist Akira Horiuchi won the medical education prize for an experiment in which he reviewed the comfort and efficiency of self-colonoscopy in the sitting position by performing a colonoscopy on himself while seated. He reported only “mild discomfort.” There are pictures of him performing this procedure. Of course there are. Other winners included a team that demonstrated that most people who use complicated products do not read the instruction manual (Literature Prize). For the Ig Nobel Peace Prize researchers surveyed Spanish drivers to determine the frequency, motivation, and effects of shouting and cursing while in a car. The Economics prize went to a group that investigated whether using Voodoo dolls to retaliate against abusive bosses makes employees feel better. Finally, the Chemistry prize was awarded to a team that tested the effectiveness of a “spit shine” by cleaning 18th century sculptures with saliva and and compared the results to several alcohol-based cleaners. Spit won. <a href= "http://www.sciencemag.org/news/2018/09/ig-nobel-prizes-honor-do-it-yourself-colonoscopies-curious-use-postage-stamps-and-other?rss=1"> Science</a>, <a href= "https://www.bbc.co.uk/news/science-environment-45513012">BBC Science and Environment</a> <h3>Doctor Who Returns!</h3> <h4>JD Goodwin</h4> Normally we don’t cover entertainment news on this podcast...unless of course, it has to do with Star Wars, Star Trek, or other significant sci-fi stuff. Among that venerable stuff is Doctor Who. I tip my hat to the producers of this incredibly long running television program because this next series we will be welcoming a new Doctor among that pantheon of Time Lords. What’s special about this is that the new doctor is a woman. Honestly, I’m surprised it took this long. But this is one among many glass ceilings I’m happy to see broken. Broken? I mean shattered. I just read that the woman playing the new Doctor, Jodie Whittaker, is getting paid the same as what the boys did. This is significant because there’s been quite a row recently about pay disparity among female and male BBC employees. Thankfully, such is not the case with Doctor Who. When asked about this by Metro News, Jodie Whittaker replied, “I absolutely know that I’m not being paid less than any other Doctor”. I’m talking about Doctor Who’s who go all the way back to William Hartnell, to Tom Baker, to Paul McGann, to David Tennant and all those in between. Quite a Whose Who of Who’s, isn’t it? I’m really looking forward to beginning this next journey with the new Doctor, and that begins on 7 October with the episode titled The Woman Who Fell To Earth. Don’t miss it. Doctor Who on 7 October! <a href= "http://www.sciencemag.org/news/2018/09/ig-nobel-prizes-honor-do-it-yourself-colonoscopies-curious-use-postage-stamps-and-other?rss=1"> Science</a>, <a href= "https://www.bbc.co.uk/news/science-environment-45513012">BBC Science and Environment</a> <hr /> <h2>Pub Quiz</h2> <ol> <li>On what date did the very first Doctor Who premiere?</li> <li>Why was this a particularly unfortunate date to debut a television show?</li> <li>Who played the very first Doctor?</li> <li>The fourth Doctor, played by the inimitable Tom Baker, is known for a particularly extreme version of what item of clothing?</li> <li>What did the fifth Doctor, played by Peter Davison, wear on the lapel of his jacket?</li> <li>Peter Davison has a famous son-in-law.

It is thought that these beams are originating from expired suns; neutron stars. These small but massive bodies produce radio wave signals like the ones that we’re talking about and the spinning of these neutron stars produces the sweeping waves which have been detected. These bodies are being referred to as pulsars. I’m sorry? What’s that? You’ve heard all this before and it’s not really science news? Well, I grant you that this discovery was made in 1967 so there is a chance that you may come across it before. So why are we talking about this in our news section? Because Jocelyn Bell Burnell, the Cambridge graduate student who made the discovery, is finally receiving an award for this work. Now, I don’t think that anyone would argue that this work deserves a big prize like this (and it is a big prize; a $3 million big prize), but what gives with waiting so long to award it? If you thought that it took a long time to get a Nobel prize, that’s nothing in comparison to this 50 year wait. To be fair to the issuers of this prize, the Breakthrough Prize in fundamental physics, it was only founded in 2012 and since that time it has been only been awarded 3 other times: for the theorising of Hawking radiation and the discoveries of the Higgs Boson and gravitational waves. All of which, I think that you will agree, are pretty big deals. Of course, 50 years on and Burnell is no longer actively researching so she has decided to donate the money to initiatives that promote diversity within the sciences. <a href= "https://www.sciencenews.org/article/jocelyn-bell-burnell-physics-prize-pulsar-discovery-interview"> Science News</a>, <a href= "https://www.washingtonpost.com/news/morning-mix/wp/2018/09/07/she-made-the-discovery-but-a-man-got-the-nobel-a-half-century-later-shes-won-a-3-million-prize/?utm_term=.799fcf80a8bd"> Washington Post</a>, <a href= "https://www.bbc.co.uk/news/science-environment-45425872">BBC News Science and Environment</a> <h3>ISS: Spacecraft hole could be 'deliberate'</h3> <h4>JD Goodwin</h4> Remember last week when we reported on the air leak on the International Space Station? There was some speculation that it could have been caused by a micrometeoroid. Well, that doesn’t seem to be the case. According to Dmitry Rogozin, head of the Russian space agency, it looks as though this little hole was created by a drill and not some hypersonic space pebble. Furthermore, Rogozin suggested that this may have been “deliberate”. If you remember from the story last week this leak was not catastrophic. It was more of an annoyance. And they patched it up with space duct tape. Rogozin said, "There were several attempts at drilling,” and if you look at the pictures you can tell this is true because it was a shi**y job of drilling...the drill bit apparently skipped on the surface before biting through. The discussion right now seems to be on where this hole was drilled...as in, did this happen in space, or did the unauthorized drilling occur on the ground? The good money says it happened on the ground. They expect that a technician goofed, and covered up his hole with some kind of adhesive, which eventually dried up and fell away. However, in a televised interview Mr. Rogozin seemed to go all-in when he said: "What is this: a production defect or some premeditated actions? We are checking the Earth version. But there is another version that we do not rule out: deliberate interference in space." An investigation is going on right now and they intend to identify whoever did this, by name, accident or not. Russian politician Maxim Surayev even suggested that it could be one of the cosmonauts who wanted to cut short his or her low orbit holiday. He said, “We’re all human and anyone might want to go home.” I’ve a feeling this isn’t the last we’re gonna hear about this story. Watch this space. Get it?! <a href= "https://www.bbc.co.uk/news/science-environment-45423225">BBC Science and Environment</a>, <a href= "https://www.smithsonianmag.com/smart-news/someone-drilled-hole-international-space-station-180970208/"> Smithsonian</a> <h3>Fishermen Haul in Monstrous Skull and Antlers of Extinct Irish Elk</h3> <h4>Chris MacAlister</h4> Let me paint a picture for you. You’re at sea, on a fishing ship. Working long hours and lacking in sleep. So how quickly do you believe your own eyes when your net comes out of the sea containing a skull. I’m not a commercial fisherman but I’d imagine that they pick up random stuff from the sea floor all the time, but this time is was different. This was no ordinary skull. The skull was 6 feet wide! Let me stress that again: 6 FEET WIDE! This was due to two massive antlers sticking out of it. Now, I must admit that this story isn’t completely accurate. The fishing boat was actually only about half a mile from shore and the water was no more than 20 foot deep, but that’s where my liberty taking ends: everything about the skull is true. It turns out that this skull is at least 10,500 years old and it is the remains of an Irish Elk and I guess that the people who originally discovered this species did not want anyone to be in any doubt about its size when they dubbed it Megaloceros giganteus. For those of you not up on your latin and greek, let me translate: Large Horns Gigantic. Subtle, don’t you think? And appropriate as these are the largest example of this type of animal ever discovered. I can poke fun at the name as much as I like but it’s a damn sight better than the common name: Irish Elk as the animal was not exclusively irish and it wasn’t even an elk! This DEER lived throughout Europe, Northern Asia and Northern Africa, it’s just in Ireland where most examples of it have been discovered. The local irish authorities ares still working out where this skull will eventually call home. Until then Raymond McElroy, who found it, has it safely preserved for posterity...in his garage. <a href= "https://www.livescience.com/63521-giant-elk-skull.html">Live Science</a>, <a href= "https://www.irishtimes.com/news/ireland/irish-news/antlers-of-extinct-giant-irish-elk-found-at-the-bottom-of-a-lake-1.3620791"> The Irish Times</a> <h3>California governor signs law for clean energy by 2045</h3> <h4>JD Goodwin</h4> California, the land of fruits and nuts, and probably the most sensible place in the United States when it comes to climate change. My home state just passed a bill, signed into law by our governor Jerry Brown, that commits us to using 60% carbon free electricity sources by 2030, and to using exclusively carbon free electricity by 2045. Governor Brown also pledged to abide by the 2015 Paris Climate Agreement. I’m sure the Trump administration is thrilled by this...NOT...especially after they pulled the United States out of the same Agreement. This is no empty gesture. If California were its own country, an idea that sound more appealing with each day, if we were our own country we’d have the fifth strongest economy on the planet. Predictably most Californians are very happy with this new law, but there has been some predictable opposition by utility companies. A statement from a Pacific Gas & Electric spokesperson stated that this wouldn’t be affordable or sustainable. Most homes in California can meet ALL of their electricity needs by installing solar. Solar is already being required by building codes in many areas, and it won’t be long before having solar and a home battery will be just another part of owning a home. Free electricity from the sun, and a way to store it on site. Now you can see why utility companies are against this. Also, this new law has been enacted with a bit of good timing. This week Governor Brown is hosting the Global Climate Action Summit in San Francisco, which started yesterday and ends tomorrow. <hr /> <h2>The Climate Lounge</h2> <h3>Climate Change and Hurricanes - What’s the Deal?</h3> <h4>Tom Di Liberto</h4> This episode in The Lounge we are going to talk hurricanes. Mostly because the tropics have gone absolutely nutso with tropical cyclones right now. There are nine storms spread across the Atlantic and Pacific right now with a potentially historic and horrible hurricane currently churning in the Atlantic bound for the east coast of the United States. The other reason I want to talk hurricanes is that well, though I host The Climate Lounge and work in climate communication and science, I originally got started with this whole atmosphere thing as a meteorologist. So talking about the current forecasts for hurricanes is sorta my thing too. Don’t worry I’ll get to the climate angles eventually… like… RIGHT NOW Hurricanes and climate change. What can we say? I’m sure you’re thinking I’ll say that you can’t attribute any one storm to climate change but as I’ve said before, that’s just a really silly way to frame this. You can’t really attribute one storm to natural causes entirely either… which means that your framing of that question is dumb. So let’s not do that. Instead let me quickly list the ways that climate change affects hurricanes and their impacts. Then I can get into all the weather info about hurricane Florence. <ol> <li>Sea level rise has made coastal flooding easier and more dangerous. This is one of those sorta obvious things. If you start with a higher sea today than two storms on that occurred 50 years ago and one today wouldn’t have the same flooding impacts. Todays storm would push water higher than the storm 50 years ago. And our coastal infrastructure wasn’tbuilt for that.</li> <li>We can’t say if the number of storms themselves are increasing but we can say that the stronger storms are getting stronger globally. Research suggests a roughly 8m/s increase in wind speed per degree celsius of warming.</li> <li>Warmer oceans mean more moisture in the air which means heavier rains from hurricanes. Research here suggets a roughly 7% increasein moisture in the air for each degree Celsius of increase in SSTs.</li> </ol> This is all pretty conclusive science without getting into more complicated nitty gritty stuff like how storms are tracking farther to the north and will continue to do so since SSts are warming up enough to sustain them.Or that there is research that suggests that a warming arctic may lead to more stalling storms. So with just that we can see that climate change can have an impact. But let’s talk about this current storm briefly and a concept that is important in a world that will experience more weather/climate extremes. Hurricane Florence, as of this recording has 130mph winds and is expected to make landfall near the South Carolina North carolina border as a major category 3 hurricane around September 14 and then stall out somewhere. Depending on where it stalls out and for how long could mean the difference between 5-10 inches of rain or an absurd 20-40 inches of rain. And while we often talk about winds when it comes to impacts from hurricanes, it’s actually water (storm surge and inland flooding which kills most people in a storm. So how do some people stay and dont evacuate? Beacuse people often fear wind more than water and often have difficulty comparing once in a lifetime events to anything else. After all, how do you imagine the impacts of something that’s never been seen before.We often see quotes from people being rescued that say “but ive never seen it this bad”. But even then, the people who don’t leave are often those who can’t. The poor, immobile, eldery. They don’t have the ability to up and run when a storm is coming. They don’t have access to local disaster plans. They might live in old flood prone areas. And that gets into topics of environmental justice. So let’s hope for the best with hurricane Florence and everywhere else affected by hurricanes. But let’s keep in mind that these extreme events also help to make much more visible the sort of environmental vulnerability that exists in our societies that often times are hidden away on a sunny day. <hr /> <h2>Pub Quiz</h2> <ol> <li>What was the last year in which Atlantic hurricanes were named exclusively after women?</li> <li>In 1979 the new era of giving hurricanes male as well as female names began, and it did so with the second named storm of that year. What was that hurricane’s name?</li> <li>Tom Frieden, the former director of the Centers for Disease Control and Prevention from 2009 until 2017, made news recently. Why?</li> <li>A rare disease that's related to smallpox has shown up in the United Kingdom for the first time. What disease is this?</li> <li>Staying in the U.K., the children’s novel “Wind In The Willows” features a character named Ratty, based upon a real-life mammal. The real-life version of Ratty has just been reintroduced to a stretch of river in Somerset. What mammal is this?</li> </ol> <hr /> <h2>In Closing</h2> And that concludes this episode of the Blue Streak Science Podcast.

084: A Leak On The International Space Station
The observation of a decaying Higgs’ Boson | Skull tunnels | Troubleshooting on the International Space Station | Rates of STD infections in the United States go way up |The Climate Lounge |Pub Quiz <hr /> <h2>Science News with Nevena Hristozova and Chris MacAlister</h2> <h3>Physicists Observe the Higgs Boson’s Elusive Decay</h3> We struggled for 50 years to detect it, and now we can’t wait to see it die! It’s the Higgs. The boson, not the Professor! Luckily, Professor Peter Higgs is still alive and well at the age of 89. And I’m talking about the decay of the higgs boson - because only by knowing how a particle is born and how it dies one can truly understand it - I’m so poetic! But it’s true. Now the two largest experiments at the Large Hadron Collider in Geneva ATLAS and CMS have found another manner via which the boson decays - into bottom-antibottom quarks. This most common decay pattern was surprisingly hard to detect, even if more than 50% of the time the higgs decays like this. Previous observations included its decay into two photons and an electron–antielectron pair, when counterintuitively this is predicted to happen just about 0,2% of the time. But then again, I never claimed that theoretical and particle physics were in any way intuitive to me! <a href= "https://www.nature.com/articles/d41586-018-06130-9">Nature</a>, <a href= "http://www.sciencemag.org/news/2018/08/after-years-effort-physicists-spot-higgs-boson-decaying-most-ordinary-way?rss=1"> Science</a>, <a href= "https://www.scientificamerican.com/article/physicists-observe-the-higgs-bosons-elusive-decay/"> Scientific American</a> <h3>Newfound skull tunnels</h3> We did indeed, so let me return to our tale of brains, bones and blood. Humankind has been examining all aspects of our bodies, both inside and out, for as long as we have had them, which makes it even more remarkable that we are still finding new features in it. The most recent being a network of tiny tunnels within the cranium. These tunnels are like a window to the bone marrow which is immensely important for a variety of reasons but notably, it is where our blood is made. Not only our red-blood cells but also the white blood cells that form the backbone of our immune system (no pun intended). It used to be believed that first response white blood cells (neutrophils to be precise) travelled from all areas of the body to wherever they happen to be needed. Note the “used to be” guess what’s coming next! By providing the cranial marrow with fluorescent dye the team from Harvard were able to measure the proportion of these cells that were appearing in the brains of stroke sufferers, where the immune system is having a field day. What they found was that most of the cells, by far, had originated in the cranium rather than elsewhere in the body. So the question was now; how do the neutrophils get from the marrow to create this sprinkler system of a immune response? This is what inspired the search that eventually discovered these tunnels. A key part of the body’s standard immune response is inflammation. Whilst it does a great job, there can be times where it causes more problems than it solves and the brain tends to be one of these cases. Additional pieces of information like this about how the immune system works within our brains could eventually lead to advancements in the treatment of conditions such as Alzheimer's or multiple sclerosis. <a href= "https://www.sciencenews.org/article/skull-tunnels-immune-cells-brain-injuries"> Science News</a>, <a href= "https://www.the-scientist.com/news-opinion/tiny-tunnels-run-from-the-skull-to-the-brain--study-64730"> The Scientist</a> <h3>Air Leak on the ISS</h3> Oh oh! We’re in trouble! This is how the international space station would have sounded like few days ago if there was enough atmosphere up there to sound like anything at all. A small dip in cabin pressure was noticed by ground control on Wednesday 29 august. Then the astronauts started searching for the hole. Turned out, the leak was via a 2-millimeter-wide hole in one of the two Russian Soyuz spacecraft that's currently docked to the orbiting lab. As of today, the damage is repaired and no risk threatens the integrity of the ISS or the life of the astronauts. Russian space officials have said that the puncture was caused by a micrometeoroid, but NASA has not confirmed this. Was it may be a piece of space debris? Or may be normal wear and tear of the materials? Or an alien laser weapon? What I was most curious is HOW you find a 2mm hole in a 108.5 meters by 72.8 meters pace ship covered with insulation, thousands of pipes, tubes, instruments etc…. I tried to find out, JD, but it didn’t say… I place my bet on releasing some compressed air with a colorant in it and following where does it escape from. If NASA or the ISS are listening - call us - we want to know! <a href= "https://www.scientificamerican.com/article/small-air-leak-detected-on-international-space-station/"> Scientific American</a>, <a href= "https://www.space.com/41694-space-station-air-leak-fixed.html">Space.com</a> <h3>S.T.D. Diagnoses Reach Record 2.3 Million New Cases in U.S.</h3> Well, JD; what have I got for you. Chlamydia, how does that suit you? No? Not for you? Okay, what about syphilis? Gonorrhea? Take your pick, I’ve got them all. I mean, not me personally; but my story has, because this is the news that sexually transmitted diseases are on the rise in the United States. Not only are they on the rise, they have just hit a diagnosis record with 2.3 million new cases in 2017. In the previous 4 years syphilis cases have increased by 76%. So what the hell is going on? It’s often tricky to make a direct link between cause and effect and in science we must always remember that correlation does not equal causation, but that said. Here are some fun correlations: <ol> <li>Screening and diagnosis is improving. If you are checking more people in more effective ways then you are bound to discover more cases. And this then inflates because as you diagnose new and expecting mothers you then go on to check their new babies who are getting diagnosed as well.</li> <li>Online dating is increasing and it is successful. So when more swipey-swipey leads to more bouncy-bouncy then you get more itchy-itchy.</li> <li>Condom use is decreasing. Can you believe that in this day and age we are actually going backwards in this? This could in part be down to men assuming that women are taking control of contraception but it could also be linked to correlation number 4...</li> <li>The Centers for Disease Control and Prevention’s STD budget has been slashed by 40% since 2003. Now we give the Trump administration a fair bit of stick on this show, and rightly so, but multiple administrations bare some responsibility for this one. Trump may claim to be different from his predecessors but even he has a further 17% cut lined up for next year.</li> </ol> Some may argue that people don’t need telling about how STDs spread so no budget is needed, but not everyone realises that you can spread one far and wide before you even present any symptoms. That’s exactly why these diseases spread so well. They say that the world needs more love and I stand by that sentiment, but for pitties sake people; be careful when you go out to do your bit. <a href= "https://www.theatlantic.com/health/archive/2018/08/gonorrhea-syphilis-chlamydia-budget-cuts/568837/"> The Atlantic</a>, <a href= "https://www.nytimes.com/2018/08/28/health/std-chlamydia-gonorrhea-syphilis.html"> New York Times</a> <hr /> <h2>The Climate Lounge</h2> Welcome!

I get it, not my best, but it’s hot where I am and that’s the best I’ve got). <img class="alignright size-full wp-image-1430" src= "https://bluestreakscience.com/wp-content/uploads/2018/09/hotenoughforya.png" alt="" width="400" height="300" />An urban heat island is a metropolitan area that becomes much hotter than its surrounding areas due to built up human infrastructure. Things like concrete and asphalt can absorb radiation during the day and re-radiate it not only throughout the day but also at night leading to drastically warmer daytime and nighttime temperatures in cities compared to surrounding areas. Now if you don’t want to take my word for it. Test this out the next time it’s hot outside.Stand on an asphalt pavement and then walk over to a grassy shaded area and tell the difference in heat. There’s a difference. Or just take my word for it and don’t bother making yourself feel uncomfortably hot and get all sweaty and gross and yuck. In the summer, this can mean hot days that tip to extremely and dangerously hot days affecting the elderly, sick and young. In fact excessive heat is seen as the greatest weather-related cause of death in the United States. Now satellites have been able to map this on a large scale but scientists with NOAA, Portland State and the Science Museum of virginia has started doing on the ground heat island studies to map just how different conditions can be from neighborhood to neighborhood. This level of detail is missed out on satellites and can have profound effects on how cities deal with heat in the future as temperatures continue to warm due to human caused climate change. Washington DC for instance averages 5 days a year over 95. That could jump to 20 days by 2030, 40 days by 2050 and 80 days by 2100. Recently, these scientists along with citizen scientists and volunteers in Washington DC and Baltimore maryland, headed out with temperature sensors mounted to their car windows to monitor conditions through different transects through each city at three times during the day, morning 6am, peak heating during the mid afternoon 3pm and evening 7pm. Soon enough scientists will be able to look through the data and see exactly which areas are hottest due to the urban heat island. But we don’t have to wait to see this sort of impact. A similar study led by the same scientists, Jeremy Hoffman, and Dr. Vivek Shandas was completed last year for Richmond,VA. They found a 16 degree difference 87 to 103 at the hottest part of the day in the same city! And more importantly, they were able to show that the neighborhoods that tend to get smacked hardest by the urban heat island are poorer neighborhoods and areas where ambulances are already called more often to deal with heat related problems. Now we can fix this. Cities can use more reflective materials when building, remove pavement for grass, plant trees, add living roofs but it’s an effort that has to be taken at a city-county-state and federal level to deal with. And this sort of study is just the first step in helping cities find out just exactly where things are the worst and where actions need to be taken immediately to help community members. Because often times the folks hardest hit, are often already the most vulnerable people in our communities. So let me end with the final lines from that poem I started off with as I think it’s a great reminder in our climate changed worlds. Any man’s death diminishes me, Because I am involved in mankind, And therefore never send to know for whom the bell tolls; It tolls for thee.

083: Evidence of Neanderthal/Denisovan Hybridization
<h3>Seriously, an empathy expert under fire for bullying? | Mama is a Neanderthal and Daddy is a Denisovan | Earth's Quick Flippin' Magnetic Field | Ancient Turtle Had No Shell | A****** of the Month: Tokyo Medical University | Pub Quiz</h3> <hr /> <h2>Science News with Amrita Sule and Sophie McManus</h2> <h3>Empathy Researcher Accused of Bullying</h3> I think this story deals with a very important issue in academia which is often not reported: bullying. Tania Singer, a 48 year old neuroscientist, director at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany has been accused of bullying and intimidation by her former colleagues. She is one of the world’s leading experts on empathy research and has spent her entire career studying and understanding human nature. Max Planck institute was brought to notice about this bullying behavior last year. They started investigating the allegations last year and allowed her a year long sabbatical. However, they plan to bring her back to the lab and this is when the current and former lab members spoke to Science. In an interview with science magazine, 8 former and current researchers from Max Planck Institute for Human Cognitive and Brain Sciences have accused Singer for manipulative and abusive behavior. The allegations include but are not limited to emotional abuse. Many one on one meetings have ended in tears for the lab members. Also, singer frowned up any female members getting pregnant and made no allowances for any medical appointments among others. This is also ironical because one of Singer’s goals emphasized in a book she wrote in 2013) is to bring more attention to compassion in our society. More and more bullying cases are surfacing every now and then. A leading cancer geneticist Nazneen Rahman from Institute of Cancer research UK faced harassment and bullying allegations which dated around 12 years back. She is quitting her job next month. But let’s not forget that the onus is is on the institutions to take these matters more seriously and also create a work environment where employees can fearlessly report such instances. <a href= "https://www.washingtonpost.com/news/speaking-of-science/wp/2018/08/12/shes-world-renowned-for-studying-empathy-her-colleagues-say-shes-an-intimidating-bully/?utm_term=.9bf15e543bd7"> Washington Post</a> <hr /> <h3>Mama is a Neanderthal and Daddy is a Denisovan</h3> Researchers have analysed DNA from the fragment of an ancient child’s bone. This bond represents the first example of a first-generation hybrid human - Dad was a Denisovan, Mum was a Neanderthal. The girl, named Denisovan 11, affectionately nicknamed Denny, died 90,000 years ago. The study is published in the journal Nature. The team, led by palaeogeneticists from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, conducted the genome analysis on a single bone fragment recovered from Denisova Cave in the Altai Mountains of Russia. This cave gives its name to ‘Denisovans’, a group of extinct humans first identified on the basis of DNA sequences from the tip of a finger bone discovered there in 2008. Scientists already knew that Neanderthals, Denisovans, and homo sapiens interbred in the past - but this discovery is the first example of genetic material from the first generation of these couplings. In fact, Svante Paabo, one of the leaders of the study, thought his colleagues must have ‘screwed up’ when they first told him what they had found. The group knew the bone fragment came from a girl because they checked the bone fragment’s sex chromosomes. The density led them to estimate Denny was at least 13 years old when she died. The scientists even know which parental side was Neanderthal, and which was Denisovan, by looking at the bone’s mitochondria - the ‘powerhouses’ of cells. The genetic material in the mitochondria was recognised as Neanderthal. This shows the girl’s mother was Neanderthal because we only inherit mitochondrial DNA from our mothers. This finding corresponded with the fact that half her genomic DNA was matched to a Neanderthal. The Denisovan dad was confirmed by comparing the remaining genetic material to samples of Denisovans, homo sapiens and Neanderthal. Sort of like an ancient and elaborate dot-to-dot. “To find a first-generation person of mixed ancestry from these groups is absolutely extraordinary,” - quote from population geneticist Pontus Skoglund at the Francis Crick Institute in London. “It’s really great science coupled with a little bit of luck.” As ever, scientists need that little bit of luck! <a href= "https://www.sciencenews.org/article/meet-first-known-child-neandertal-and-denisovan"> Science News</a>, <a href= "https://www.nature.com/articles/d41586-018-06004-0">Nature</a> <hr /> <h3>Ancient Fossil Turtle Had No Shell</h3> A 228 million year old fossil of a turtle has been discovered in Guizhou province of south west China. The almost complete fossil is around 2 meters long and has been named Eorhynchochelys sinensis which means "dawn-beaked turtle from China”. What is so special about this discovery? This turtle fossil lacks the iconic turtle shell but has a toothless beak (which is seen in modern day turtle as well). This fossil had a long tail and probably lived near shorelines.It is possible that its broad ribs, flattened shape and strong limbs were adapted for digging the mud to hide itself , bury eggs or find food. This is the earliest turtle ever found with a sign of turtle -like beak. It joins the list of other fossils discovered previously. A fossil aged 220 million years old Odontochelys semitestacea had a partial shell but no beak. Until now there have been many gaps in the evolution of turtles. But, this discovery will help scientists in filling the gaps in the evolutionary puzzle. The fact that Eorhynchochelys developed beak before odoctochelys but not the shell indicates that some traits can evolve independent of each other. Modern day turtles have both beaks and shells, but the evolution did not take place in straight line. Some predecessors only had the beak while some had shells. This fossil discovery is going to prove helpful for scientists to understand how present-day turtles have evolved. Even though this discovery offer new insights into turtle evolution, scientists are still not sure where they will fit in the evolutionary tree. Past genetic studies have placed crocodiles, dinosaurs and modern birds as the close relatives of turtle. Studying this fossil will shed more light on the evolution of the turtle body plan and how turtles relate to other reptiles. <a href= "https://www.bbc.co.uk/news/science-environment-45261121">BBC Science and Environment</a> <hr /> <h3>Earth's Magnetic Field Can Reverse Poles Ridiculously Quickly</h3> Our planet is shielded by a magnetic field, which protects us from the hottest radiation thrown out by the Sun, thereby preventing Earth from deteriorating into a barren wasteland (although stay tuned for the next Climate Lounge to hear how we are achieving that goal all by ourselves!) The magnetic field is thanks to the molten iron core of the Earth. So far, so good! However, a few times every million years or so, Earth's magnetic field reverses polarity. Imagine an enormous magnet inside our planet gets flipped upside down - the magnetic North Pole would become the magnetic South Pole, and the energy field that typically makes up our planet's magnetic armour would weaken and break. Studies modelling this suggest that such an event would reduce the shield's protective strength by up to 90 percent. Hmm, do visions of an electrified wasteland beckon. The last full reversal of the field was around 800,000 years ago and took hundreds of years to unfold. But wait - maybe we should worry! A new study is out in PNAS, suggesting such reversals may occur more rapidly than previously thought. Uh oh. The team of scientists analyzed millenia of geomagnetic history coded into the atoms of an ancient stalagmite in China. This story written in stone told them that once, about 98,000 years ago, the planet's magnetic field suddenly flipped polarity in as little as 100 years — roughly 30 times faster than the generally expected rate, and 10 times faster than what was thought to be the fastest rate possible. For now, we don’t have to worry - but if such a magnetic field reversal occurred in tandem with a solar storm, the likely result of this solar tantrum would be power outages on a scale never seen before. <a href= "https://www.livescience.com/63414-magnetic-field-rapid-reversal.html"> Live Science</a>, <a href= "https://www.space.com/41604-magnetic-field-rapid-reversal.html">Space.com</a> <hr /> <h2>A****** of the Month</h2> <h3>Tokyo Medical University</h3> In Japan the government of Prime Minister Shinzo Abe has been boasting about its program of “womenomics” (women economics?). This has been more of a goal than a reality certainly as, according to the World Economic Forum’s rankings of gender equality, Japan remains mired down at number 114 out of 144 countries. So it came as a shock to some, and not shocking at all for others, when it was announced that Tokyo Medical University has been subtracting scores for women’s exams to get into this prestigious medical school. This has been going on for more than a decade. An investigation showed they were subtracting scores for women applicants in a deliberate effort to keep their numbers down, and also falsifying exam scores to help specific men get into the school, like the sons of politicians. The managing director of the university, Tetsuo Yukioka said, “We have caused a great amount of trouble to everyone and betrayed the trust of society. I apologize from my heart." Here’s how the manipulation worked: in the essay section of the entrance exam, which was scored out of 100, they first subtracted 20 percent from all marks. Then it gave 20 bonus marks to men who had taken the exam three times or less. So if a woman and a man had both taken the exam and scored 70 out of 100, the woman was given a score of 56 while the man was given a score of 76. The proportion of women admitted to Japanese medical schools has risen steadily when it peaked at 34 percent in 2003, but hasn’t moved since then. Interesting fact: Japanese women have a higher pass rate on entrance exams for almost every other university subject. However, in medicine the pass rate is 6.85 percent for men and 5.91 percent for women. Even with these incredible obstacles women pass the the test at less than one percentage point less than men. Why the hell would they want to keep their best and brightest out of medicine? Sources at the university have stated: <ul> <li>This was done because women are more likely to leave medicine when they have children which puts pressure on already overworked doctors.</li> <li>The University has the legal right to accept whoever they want.</li> </ul> I’m ignorant of Japan’s maternity leave structure, but one good step towards making the above point moot is to provide both mothers and fathers equal time of paid leave when a new child comes into their homes. In any case, this policy of institutional suppression is complete bull**** and must be ended immediately, and there better be some jail time as a result of this. Tokyo Medical University, you’ve been crowned the month of August’s Blue Streak Science A****** of the Month. <hr /> <h2>Pub Quiz</h2> <ol> <li>A mind-bending problem in pasta physics was finally solved last week, but the solution comes with a twist.

082: Dr. Kaeli Swift - Crow Thanatology
<ul> <li>We talk with crow researcher Kaeli Swift about a really interesting aspect of crow behavior</li> <li>Science News</li> <li>The Climate Lounge with Tom Di Liberto</li> <li>The Pub Quiz</li> </ul> <hr /> <h2>Science News with Sophie McManus and Chris MacAlister</h2> <h3>Cancer drugs may help the liver recover from common painkiller overdoses</h3> Painkiller overdoses can be lethal. In America, these overdoses occur around 100,000 times a year, both accidentally and in suicide attempts. Consequently, such overdoses are the leading cause of acute liver failure. A study published in Science Translational Medicine raises hope that experimental cancer drugs may alleviate the damage caused by painkiller overdose - and do so better than the current antidote, N-acetylcysteine, which must be administered within four hours to avert death or avoid the need for transplant. The new drugs were still effective 12 hours after overdose had occurred. The cancer drugs tested appear to work by blocking action of a common molecule, TGFbeta, which in this case is activated by inflammation and can cause liver cells to enter senescence - a pre-death state. It’s hoped this strategy might be effective in clinical trials, thereby buying doctors in A&E some extra time with which to deal with OD. <a href= "https://www.sciencenews.org/article/cancer-drugs-may-help-liver-recover-common-painkiller-overdoses"> Science News</a> <h3>Earliest galaxies found 'on our cosmic doorstep'</h3> When you think about the oldest known galaxies in the Universe then your thoughts may be drawn to MACS1149-JD. I know that mine is! This is the most distant galaxy ever observed. Over 13 billion light years away and thanks to the speed of light we know that it’s over 13 billion years old. So how bizarre would it be to learn that there are galaxies just as old, if not older, right here neighbouring the milky way? This bizarre because that is exactly what is happening! They’ve been discovered by a team at the Harvard-Smithsonian Centre for Astrophysics at Cambridge. Now if you are like me then you will be thinking, how can they tell that these galaxies are so old? Well I’m glad that you asked; it comes down to their luminosity function, which is a measure of the radiation that they generate. The luminosity of these galaxies has a distinct signature consistent with that theorised to be produced in the cosmic dark ages. This was a unique period of the universe’s history when atoms first formed and the cosmic microwave background, along with all other electromagnetic radiation started to form. <a href= "https://www.bbc.co.uk/news/science-environment-45198764">BBC News Science and Environment</a> <h3>Crows Tidy Up Amusement Park in France</h3> Crows have been taught how to tidy! It's a shame more people haven’t. Rooks will be deployed this week at Puy du Fou, a French park that hosts events and re-enactments. The birds were bred in captivity and then trained by Christophe Gaborit, a falconer and project manager with the park's Academy of Falconry. These birds are highly intelligent and you might see them around sifting through bins to try and find something to eat. Because of this intelligence and ability to sort items, Christophe decided to turn this behaviour to good use. He raised and trained his first pair of trash-collecting rooks in 2000, with a little help from a special cabinet — when the birds deposited rubbish in the drawer, a second compartment would be opened to reward them with a tasty treat. Repeating this action led the rooks to associate rubbish removal with food. Sometimes they’d try to trick the system by dropping bits of wood in the box instead of rubbish. Gaborit explains all this on his blog. The logic behind employing rooks instead of humans is interesting - Gaborit hopes that the sight of crows picking up litter will prompt people to be a bit more thoughtful in how they dispose of rubbish. After all, it isn’t hard to drop something in the bin... <a href= "https://www.livescience.com/63320-crows-pick-up-trash-theme-park.html"> Live Science</a> <hr /> <h2><img class="alignright size-medium wp-image-1403" src= "https://bluestreakscience.com/wp-content/uploads/2018/08/82_image-300x300.png" alt="" width="300" height="300" />Interview with Dr. Kaeli Swift about Crow Thanatology</h2> Firstly, congratulations to Dr. Kaeli Swift!

Today, I’m going to talk to you about re-birth. In a beautiful article in the Huffington Post, Kaia Findlay reports on just how resilient ecosystems (both natural and human-influenced) in Puerto Rico have been in the aftermath of Hurricane Maria. The story also comes with unbelievable videos of Puerto Rico in the aftermath of the storm. <h4>El Yunque Rain Forest</h4> [caption id="attachment_1405" align="alignright" width="400"]<img class="size-full wp-image-1405" src= "https://bluestreakscience.com/wp-content/uploads/2018/08/ElYunque.png" alt="" width="400" height="300" /> El Yunque Rain Forest[/caption] Let’s start with the rainforests. Forests cover 60% of Puerto Rico and are a vital part of what makes Puerto Rico, Puerto Rico. And after Maria, an estimated 23 to 31 million trees were killed or damaged. The famed El Yunque rainforest was turned a shocking brown. Just listen to this quote. “It was a toothpick forest...like a bomb hit,” said Grizelle Gonzalez, a soil scientist at the International Institute of Tropical Forestry. As someone who adores autumn and the leaves changing color, and who loves a nice winter stroll through a barren forest, that last quote got me. But, you can’t keep El Yunque down. You can’t keep nature down. Nature has a long history with the weather. And it’s ecosystem is already rebounding because it’s adapted to do so. Plants who love the sun quickly rose up under the brand new open canopy of the rainforest. Eventually they will grow tall enough to offer enough shade for the shade loving plants to flourish. And the rainforest begins anew. <h4>Tabonuco Tree</h4> Take the Tabonuco tree. One of the larger trees in the rainforest, they are found along the higher ridges, in areas more susceptible to high wind speeds during hurricanes. Yet after Maria, there they stood. Leaf-less but alive. How?They have evolved to the risk of storms by having a large interconnected root system which help to anchor them all. And once the storm passes, they can quickly grow back their leaves. There are more resilient tree species like the Cecropia schreberiana which can rapidly grow 50 feet in the post-Maria landscape. Six months after Maria hit, all of those sun-loving plants had already begun to cover the rainforest floor with trees already poking through the undergrowth. In 10 to 15 years, a visitor won’t be able to tell that anything happened. And in 100, it would take hard scientific research to even know a hurricane came through. <h4>Farmer Prepares for Storm</h4> That’s nature though. But there are farmers in Puerto Rico who have taken this natural adaptation of Puerto Rico’s land and applied it to their farms. Ian Pagán Roig woke the day after Maria to see his farm decimated, trees down, surrounding forest denuded, pools of water everywhere. Yet a month after Maria, there he was producing crops again. How? Prior to the storm, Pagan took important steps like digging trenches for water drainage, removing the roof of his greenhouse to allow for the wind to blow through. And prior to the hint of any storm, Pagan built permanent infrastructure like ponds and a greenhouse to make returning to normalcy quicker. And most important, his farm equipment ran on grass not fuel. While fellow farmers waited hours and hours on line for gas, his two oxen where out plowing land. Combining these choices with natural agricultural practices that enhanced his soil vitality had his farm up and running so quick after Maria. The main thing is that the earth is resilient. And people can be too… if we put the effort in. <a href= "https://www.huffingtonpost.com/entry/puerto-ricos-natural-revolution-after-hurricane-maria_us_5b5f3dffe4b0b15aba9b4daf"> HuffPo</a> <hr /> <h2>Pub Quiz</h2> <ol> <li>Using data from NASA's Moon Mineralogy Mapper instrument, scientists have identified three specific signatures that definitively prove there is what on the surface of the moon?</li> <li>This week, a consortium of more than 200 scientists from 20 countries published the first fully annotated sequence of the genome for what very important species of plant?</li> <li>What food was recently found in a 3,200 year old Egyptian tomb?</li> <li>A 'Fireball' 40 Times Brighter Than the Moon was seen streaking across the sky of what U.S. state?</li> <li>A purple celestial phenomenon, recently discovered by citizen scientists, has been given a name.

The explorer who brought us Pluto in all of its glory; with its heart and fart dunes, has something new to report on its way to its next rendezvous with Ultima Thule, an ultraviolet glow. So what could be causing a glow in deep space? Well the experts are all in agreement. It’s aliens. Aliens people, they’ve finally come! If only we had a space force to save us. Sorry, my error. It’s not aliens, it’s Hydrogen. The general consensus is that this glow is emanating from the edge of the heliosphere. The heliosphere is our solar system’s bubble, created by the sun’s solar winds blowing out through the solar system and it keeps interstellar matter from drifting in. So this glow is thought to be where the winds stop. Forming a hydrogen wall at the point where the wind gets weak enough for the universe to push back. <a href= "https://www.sciencenews.org/article/new-horizons-may-have-seen-glow-solar-systems-edge" target="_blank" rel="noopener">Science News</a>, <a href= "https://www.livescience.com/63297-hydrogen-wall-glowing-interstellar-space.html" target="_blank" rel="noopener">Live Science</a> <h3>New Drug for Relapsing Malaria</h3> Malaria is a disease caused by a total of 170 plasmodium species. Some infect humans, other - other animals, some cause slightly different symptoms of the same disease. In the majority of cases, the malaria plasmodium is transmitted by mosquitoes, and one species is known to be transmitted to humans via small primates. An estimated 600 million people worldwide are affected by malaria and about one to three million die each year. The good news is that the US Food and Drug Administration (FDA) has approved tafenoquine for malaria prophylaxis. Some of the malaria-causing plasmodia can remain dormant in the liver of affected patients and cause recurring infections of the patient months after the initial condition, and what is worse - they are also potentially contagious if a mosquito bites them. This new drug was specifically developed against this recurring species. It also has a strong negative side-effect though. For people with a X-chromosome related genetic condition causing deficiency in the glucose-6-phosphate dehydrogenase enzyme which protects the red blood cells from oxidative damage, taking this pill can cause hemolytic anemia - destruction of their red blood cells, so that’s a pretty significant drawback. The approval of FDA comes with the conditions for the pharma companies that make the drug to carry out further extensive pharmacovigilance tests once the drug is on the market and provide detailed reports of the results. <a href= "https://www.pharmacytimes.com/news/first-preventative-antimalarial-in-almost-2-decades-gets-fda-approval-" target="_blank" rel="noopener">Pharmacy Times</a>, <a href= "https://www.prnewswire.com/news-releases/us-food-and-drug-administration-approves-arakoda-tafenoquine-tablets-for-oral-use-first-preventative-antimalarial-approved-in-almost-two-decades-300694787.html" target="_blank" rel="noopener">PR Newswire</a>, <a href= "https://www.sciencenews.org/article/newly-approved-drug-could-be-boon-treating-malaria" target="_blank" rel="noopener">Science News</a> <h3>Debate On How People Arrived in The Americas</h3> During the last ice age, pioneering humans crossed the Bering Strait on an ice bridge and became the first human population in the New World. Simple, eh? Maybe not. Once on the continent there is still the small matter of making your way south and there are some conflicting ideas about how this would have happened. One theory says that the explorers would have hugged the coast on their way down, whilst the other says that a more inland route would have been taken, passing between two ice sheets. There is evidence to support each case, and we all know what happens when you have conflicting theories in science; fiiiiiiggggghhhhht! Mercifully, a international team of multidisciplinary experts have come together to try and shed some light on this puzzle and stop some of the carnage and bloodshed. Archeology, geology, anthropology and genetics have all been put to task to try and solve this question once and for all, the results are in, and the winner is…..La La Land. Sorry wrong card. The winner is…..we don’t know! <hr /> [caption id="attachment_1383" align="alignright" width="300"]<img class="size-medium wp-image-1383" src= "https://bluestreakscience.com/wp-content/uploads/2018/08/AmberStuver-300x300.png" alt="" width="300" height="300" /> Amber Stuver, Ph.D.[/caption] <h2>Interview with Amber Stuver, Ph.D. - LIGO</h2> Dr. Amber Stuver is an assistant professor of Physics at Villanova University and is also a member of the Laser Interferometer Gravitational-Wave Observatory, better known as LIGO.

Please have a listen to our conversation about this completely new way of discovering our universe. <hr /> <h2>The Climate Lounge</h2> Welcome to the lounge! I see that last week we covered how the death toll for Hurricane Maria in Puerto Rico was finally increased… something that should have occurred a long time ago. I was going to say that it should be a scandal. But it IS A SCANDAL. Even if most of the media has moved on and people have moved on. I’m imploring you to not move on. The island still have years, decades even left ahead in its rebuild. Is it going to be a climate resilient rebuild, or a patchwork effort that will lead to failure the next time a storm hits? I sure hope these stories reach the light of day… Ok.. onto this weeks science story. Let me set the stage… A long long time ago, in a galaxy far far away, if by galaxy, I mean region and if by region I mean Central America, I digress, a predominant technologically advanced civilization crumbled into non-existence due to, according to a new study, a change in the climate. God, please don’t let this be foreshadowing on all of us. Ok, I’m talking about the Mayans here. An incredibly, for their time, advanced civilization when it came to math and astronomy and agriculture and lore located in the Yucatan peninsula. Built up over a thousand years, the Mayan civilization collapsed in just a few hundred potentially during the 8th and 9th centuryish. What the heck happened? (pedantic note, technically we are talking about how the Mayans abandoned they massive cities in the southern lowlands of their territory over just a couple hundred of years. They didn’t vanish. And some form of mayan civilization continued for hundreds of years) Stop me if you’ve heard this before, but scientists have lots of theories. Disease, Over-population, deforestation, aliens to name a couple but one theory I want to talk about today involves a change in climate. Specifically, a stupidly bad drought. In a new paper published in Science, scientists attempted to quantify just how bad the drought was that impacted the region during the Mayan Collapse. It was called “Quantification of drought during the collapse of the classic Maya Civilization”. THREE CHEERS TO NOT PRETENTIOUS OR CONFUSING RESEARCH TITLES. (another pedantic note: this paper didn’t discover this drought, they just quantified it. Probably lots of things caused the collapse) To do this, scientists took sediment cores from Lake Chichancanab. Basically, just like an ice core, layers of soils can hold within them clues about the precipitation and temperature. What did the paper whose first author was Nick Evans a graduate student at Cambridge (have to give shout outs to first author grad students HUZZAH) find? There was a 50% decrease in annual precipitation for over 100 years from 800 to 1000 AD. And at worst, it was as much as 70%. How did they figure this out? Basically as water in the soil evaporates, lighter elements go first, leaving heavier elements behind. During particularly bad droughts, gypsum crystals form keeping within them lake water. The chemical properties of this fossilized lake water is what Nick Evans and colleagues looked at to determine how bad the drought was. A pretty amazing climate detective case. Now we still don’t know what caused the drought. It could ahve been changes in the atmospheric circulation. Maybe there were more long lasting and bad El Ninos which lead to drought? Maybe something with the Medeval warm period, a time with less volcanic activity and a stronger sun. But really that is sorta besides the point. What’s interesting for us today in a world impacted daily by human-caused climate change is just how easy it potentially was for a natural climate event, drought, to upend a thousand year old civilization. And all of those people had to go somewhere. Now think about the implications today for areas that potentially could dry out over the next century due to climate change. Add on a natural drought and you get a particularly bad scenario. And then you have millions of climate refugees. Are we are a society prepared for that? I’ll leave that one hanging. But I’m sure you might have answered that for yourself already. <a href= "https://www.washingtonpost.com/news/speaking-of-science/wp/2018/08/02/an-ancient-lake-holds-secrets-to-the-mayan-civilizations-mysterious-collapse-study-finds/?utm_term=.beb583682ecb"> WaPo</a> <hr /> <h2>Pub Quiz</h2> Taking part in the pub quiz today are: Chris MacAlister, Nevena Hristozova, and Tom Di Liberto <ol> <li>There was an annually occurring meteor shower last week.

Puerto Rico - the American territory which seems to be completely forsaken by the American administration, probably because they don’t have fancy golf courses there right now. The government claims 64 deaths between landfall in September 2017 and December 2017, while the official average comes to about 1140 people who lost their lives. Talk about fake news the government seems to be the best in cooking these up. Next to that the, months-long power shortages, the contaminated water supplies, the extreme flooding are part of the daily struggles of the people of Puerto Rico a year after the hurricane hit. Good job, to president Trump and his cabinet for taking care of their own people...] <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-hurricane-maria-deaths-20180802-story.html"> LA Times</a>, <a href= "https://www.newscientist.com/article/2175853-how-many-people-did-hurricane-maria-really-kill-in-puerto-rico/"> New Scientist</a> <h3>GOP Administration Proposes to Scrap Automobile Fuel Efficiency Standards</h3> Last Thursday, Donald Trump released a proposal to scrap federal fuel-efficiency standards for passenger vehicles. His administration has also threatened to remove California’s ability to set its own emissions guidelines. The reaction from the science community, as well as government officials in California was swift and negative. On Twitter, Governor Jerry Brown wrote, “California will fight this stupidity in every conceivable way possible.” What’s the Trump administration’s argument? <ul> <li>Current standards drive up vehicle prices</li> <li>these standards would increase the number of deaths from traffic accidents by encouraging consumers to keep driving older cars that aren’t as safe as new ones.</li> </ul> According to John DeCicco, a University of Michigan engineer who studies the environmental impact of vehicles, “I don’t believe the administration has any solid engineering or economic ground to stand on. It is basically political opportunism.” With Trump’s new proposal the projected CO2 emissions would increase by roughly 20% compared to the projected output under the current regulations. Trump’s plan would also revoke a waiver granted to California that allows the state to set air-quality standards that are stricter than those enacted by the federal government. The waiver also lets other states to adopt California's standards. Even car makers are advising the GOP administration to back off because this could create a legal mess that could get dragged out for years. We’re not gonna let this happen. <a href= "https://www.nature.com/articles/d41586-018-05832-4">Nature</a>, <a href= "https://www.nytimes.com/2018/08/02/climate/trump-auto-emissions-california.html"> New York Times</a> <h3>New Pick for White House Science Office is Not Bad</h3> Our next story takes us back to you know who! Donald Trump. Mr. Trump assumed office more than a year and half ago. Among his accomplishments is the fact that he has gone longer without a science adviser than any first-term president since 1976. Here’s the biggest surprise. His choice to be director of the White House Office of Science and Technology Policy is not a d*%#head. He is a meteorologist and his name is Kelvin Droegemeier. He’s an expert on extreme-weather events, and has been the vice-president for research at the University of Oklahoma since 2009. Kelvin Droegemeier also served on the National Science Board, which oversees the National Science Foundation, under presidents Barack Obama and George W. Bush. This guy is a good choice. Granted, he’ll be stepping into an Office of Science and Technology Policy that has been eviscerated from a staff of 130 employed by President Obama to that of only 50 by Donald Trump. But this one appointment is a good choice, and Donald Trump should be commended for it. <a href= "http://www.sciencemag.org/news/2018/07/trump-s-pick-head-white-house-science-office-gets-good-reviews?rss=1"> Science</a>, <a href= "https://www.scientificamerican.com/article/trump-taps-meteorologist-as-white-house-science-advisor/"> Scientific American</a> <h3>California Hits Its Emissions Target Years Early!</h3> JD, for a country that pulled out of the Paris agreement, showing nothing but disregard for scientific and popular opinions by the office running it, your own state is doing really well! California set a goal in 2006 to reduce its greenhouse emissions to levels equal those of 1990 by 2020. A recent study published by the Air Resources Board reviewing data from 2016 shows that California has already hit that target with few years to spare! Emissions from the power sector mark the biggest drop - around 35%. At the same time California’s economy was still growing, mind you - for those who believe that degrowth is the only way to return to healthier planet. And also, for those who believe the greener future is a poorer future - you are wrong and California just proved you wrong with very convincing numbers! <a href= "https://www.japantimes.co.jp/news/2018/07/26/world/california-met-ambitious-2020-greenhouse-gas-emissions-target-2016/#.W2PCwdhKjUI"> Japan Times</a>, <a href= "https://www.greenmatters.com/renewables/2018/08/01/1Vbqjx/california-2020-emissions-goal-reached"> Green Matters</a> <hr /> <h2>Dr. Grant Ballard, Chief Science Officer</h2> <h2>Point Blue Conservation Science<img class= "alignright wp-image-1361 size-medium" src= "https://bluestreakscience.com/wp-content/uploads/2018/08/80_350x350-300x300.png" alt="" width="300" height="300" /></h2> It was my privilege today to talk with Grant Ballard, the Chief Science Officer of <a href="http://www.pointblue.org" target= "_blank" rel="noopener">Point Blue Conservation Science</a>.

079: Heatwaves and Wildfires in the Climate Lounge!
<ul> <li>General Relativity passes the black hole test</li> <li>A day by the lake...on Mars</li> <li>The Climate Lounge</li> <li>And more!</li> </ul> <hr /> <h2>Science News with Amrita Sule and JD Goodwin</h2> <h3>Animals Frozen for 42,000 Years Wriggle to Life</h3> Not a lot of us are excited when we hear the phrase, "blast from the past”. But this time we do have news that goes about 40,000 years back. A team of researchers revived 2 nematodes from samples of permafrost in Siberia. Scientists claim that these two nematodes have been frozen since the Pleistocene, thousands of years! Previously, nematodes that were frozen for about 39 years and also tardigrades frozen for about 30 years have been revived. However, this is the first time a complex organism like a nematode has been revived after thousands of years of frozen dormancy. For this new study Russian scientists worked in collaboration with Princeton University researchers and found two viable nematodes while analyzing about 300 soil samples collected from the melting permafrost. Both are believed to be females. One permafrost sample about 32,000 years old came from northeastern part of Yakutia in Russia and the other about 42,000 years old permafrost sample came from the Kolyma River in northeastern Siberia. As these isolated worms warmed, they started moving and eating. A number of organisms native to Arctic and Antarctica are known to undergo cryo-protective dehydration i.e when they encounter freezing temperatures they rapidly dehydrate – remove water from their cells. This prevents damage to their tissues which could occur otherwise when the water in their cells could freeze and form crystals. More information would be indeed vital to understand how these two nematodes survived for thousands of years in frozen state. They would also be key in understanding evolutionary divergence between ancient and present nematode populations. <a href= "https://www.livescience.com/63187-siberian-permafrost-worms-revive.html"> Live Science</a>, <a href= "https://www.smithsonianmag.com/smart-news/ancient-roundworms-allegedly-resurrected-russian-permafrost-180969782/?utm_source=twitter.com&utm_medium=socialmedia"> Smithsonian Mag</a> <h3>Einstein theory passes black hole test</h3> The theoretical physicists come up with these elegant equations to explain everything in the universe from the very small to the very large. But it takes scientists who can design experiments to find out if the predictions of these theories line up with what’s out there in the real world. General Relativity has been experimentally confirmed many times. But one of the best things you can do with a scientific theory is to test it in the most extreme conditions to see if holds up. If it doesn’t then you have to scrap it, or revise it if possible. For the first time scientists have been able to test Relativity with an extremely massive object. How massive? Is 4 million times the mass of the Sun big enough for ya? We’re talking about the supermassive black hole in the center of the Milky Way. This black hole is known as Sagittarius A. In particular, there’s one star called S2. And S2 goes around Sagittarius A in an elliptical orbit every 16 years at 3% of the speed of light. There are other stars in the area, and only a few years ago observing these would have been impossible. But these four telescopes, located in the Atacama Desert in Chile, can overcome distortions from the earth’s atmosphere. By bringing the light together from all of them it creates a virtual super telescope. What they were looking for is a gravitational redshift. That’s when the light from this star gets stretched out as a result of a strong gravitational field. Gravitational redshift is predicted by General Relativity, and has been observed before, but not from such a massive object with its intense gravitational field. Until now. These astronomers followed S2 before and after it streaked by Sag A on 19 May and they measured it every hour. And they saw that the light from S2 was stretched, that is red-shifted, by the black hole exactly as predicted by the Theory of General Relativity. They’re not done looking at S2. The more we observe this unusual star whipping around Sagittarius A the more we can learn about the extreme conditions so close to a supermassive black hole. These results are published in the journal Astronomy & Astrophysics. <a href= "http://www.sciencemag.org/news/2018/07/star-s-black-hole-encounter-puts-einstein-s-theory-gravity-test?rss=1"> Science</a>, <a href= "https://www.sciencenews.org/article/star-orbiting-black-hole-einstein-gravity-general-relativity"> Science News</a>, <a href= "https://www.bbc.co.uk/news/science-environment-44967491">BBC Science and Environment</a> <h3>Mars May Have a Lake of Liquid Water</h3> Water is the most essential requirement for life. When planets are explored for the possibility of life, scientists first look for evidence of slightest amount of water. And much to their surprise the Italian scientists working on the European Space Agency’s Mars Express mission announced that the Mars orbiter has found a lake of liquid water below the southern ice sheets on Mars. In the past, there have been indications of presence of tiny amount of water on Mars. However, this is the very first evidence of a liquid lake that spans 20 km across and sits under the planet’s southern polar cap. Temperatures below the ice sheet could be as low as -68 degree C and pure water would freeze at such low temperatures. There is probably lot of salt dissolved in the water- thereby lowering its freezing point. This lake was discovered by the The Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument, or Marsis instrument developed by the Italian space agency. This instrument bounced radar beams on the ice sheets and the reflection revealed presence of a triangular region beneath the sheets – speculated to be a basin into which water had flown. The Italian scientists matched these radar measurements to similar ice lakes in Greenland and Antarctica on earth to confirm their observations. So, is this the evidence of life on Mars we’ve been looking for all along? Not yet. More confirmation is needed. If this holds true, it would be substantial in understanding if any organisms can, or have survived. Since, no other orbiter has detected this in spite of using a similar technology, for example NASA’s Mars Reconnaissance Orbiter, there might be debate about this and a assessment of this martial polar region might follow. <a href= "https://www.bbc.co.uk/news/science-environment-44952710">BBC Science and Environment</a>, <a href= "https://www.sciencenews.org/article/mars-may-have-lake-liquid-water-search-life"> Science News</a>, <a href= "https://www.nytimes.com/2018/07/25/science/mars-liquid-alien-life.html"> The New York Times</a> <h3>Carrie Fisher will be Leia again in ‘Star Wars: Episode IX’</h3> Last Friday the cast for the next Star Wars film was announced. And guess who’s in it? Hint: “Help me, Obi-Wan Kenobi. You're my only hope.” Not just Princess Leia Organa...but Carrie Fisher herself is playing Princess Leia. This is no little hologram or CGI generated image of her, either! Yes, Carrie Fisher died in 2016. That really happened. How are they going to do this? Star Wars: Episode 9, directed by JJ Abrams, is going to use previously unused footage from the filming of Episode 7: “The Force Awakens”. According to Abrams this has the blessing of Fisher’s daughter Billie. “Episode 9,” begins shooting next month, and is scheduled to be released December 2019. Another notable casting appearing in the new film will be Billy Dee Williams as Lando Calrissian. <a href= "https://www.washingtonpost.com/news/comic-riffs/wp/2018/07/27/carrie-fisher-will-be-leia-again-in-star-wars-episode-ix/?utm_term=.7e749afaf0ae"> Washington Post</a>, <a href= "https://www.nytimes.com/2018/07/27/movies/carrie-fisher-star-wars-film.html"> The New York Times</a> <hr /> <h2>The Climate Lounge</h2> <h3>Heatwaves and wildfires: What is going on?</h3> This week in the lounge we are just going to take a quick tour of the planet and see how things are going. I’m just going to, um, open up a browser real quick here, surely you’re impressed with my preparation, alright, let me type in weather disasters into this here google search...and. Oh god. The world’s on fire… let’s talk about this First, Europe. Europe has been sitting under a dome of high pressure that has basically let the continent slow cook. Temperatures reached into the 30s C or 90F as far north as the Arctic Circle...normal.. England has been baking. So has France.. So has… you get the picture it’s hot. A preliminary study suggests the heat wave was made 5 times more likely in northern Europe thanks to climate change. In Greece, the recent hotness combined with unusually strong west winds caused wildfires near Athens to grow incredibly out of control. The kineta fire to the west burned through rural areas and didn’t cause too much damage. But the Rafina fire 10 miles to the west was horrible. The hot dry gusty winds made the fire grow rapidly and even worse unpredictably. The fire quickly overtook the seaside resort towns near Rafina including Mati on July 23 forcing residents onto the narrow streets which quickly became clogged with cars. This led people to rush to the beaches and into the sea to protect themselves as the fires burned all the way to shore. Videos of the residents in the water while ash clouds the sky and fire burns in the distance were terrifying. Over 90 people died with dozens still missing. Making it the 5th deadliest wildfire in the past century and the deadliest in Europe. It’s a horrible shocking thing. And this happened in a place that, to be honest, wasn’t that dry. The winds were the unusual part. The European Commission’s Joint Research Centre released in January a <a href= "https://publications.europa.eu/en/publication-detail/-/publication/0e99c069-ff3b-11e7-b8f5-01aa75ed71a1/language-en"> report</a> specifically looking at the risk of wildfires in Europe in a future dominated by man-made climate change. The report found that for the Mediterranean region, the fuel needed for fires will become even drier increasing the risks for weather-driven forest fires. Making matters worse, drying conditions will extend farther north from the Mediterranean, while the large source of moisture found in the Alps will decrease as temperatures warm. In the US, hot weather has led to dumbly (is that a word, it should be) hot temperatures in California. Redding hit 110 on July 26. And it’s been hot and dry for quite awhile. A bit different than Greece. But similarly, fires broke out and rapidly grew in size. The Carr fire has burnt 110,000 acres andis only 27% contained and has burned into Redding itself. It has destroyed over 1200 buildings and killed 7 people so far including two firefighters. The freaking fire even creating this rotating fire hellscape that was like a tornado. It created its own weather. There is even a photo of a steel pipe wrapped around a tree. Meanwhile, the Ferguson fire near Yosemite killed two firefighters and caused the largest park related fire closing since 1990 burning nearly 57,000 acres. Country-wide, so far this year the burned area is 25% above-average. That’s alot Air quality in California as a result of all of the fires has been incredibly dangerous for those outside as well. Climate change… it’s making this worse but I’ve never felt comfortable saying “new normal” but I never was eloquent enough to say why. Thank god for smarter people. So let me quote Crystal Kolden a fire scientist at the University of Idaho. She noted that the behaviour of the Carr fire is not the behavior firefights are used to seeing in the middle of the night, instead it’s more normal during the hottest parts of the day. She says” That sort of extreme, it’s something we have seen a lot in the past couple years, but it’s something we’ve been seeing more frequently with a greater magnitude ofr the last 20, 30 years. “ But she pushed back on saying this is a new normal because “That implies that it’s not going to get that much worse. But what our projections tell us is that it’s going to get worse” Of course she’s right. SHE’S A FREAKING FIRE SCIENTIST. As temperatures warm, the fire seasons get longer, the fuel gets drier, and drier more plentiful fuel means if fires form they grow fast and large. Not surprisingly, In <a href= "https://www.climate.gov/news-features/featured-images/risk-very-large-fires-could-increase-sixfold-mid-century-us"> recent research</a> looking at trends in weeks where conditions are favorable for very large fires, scientists found that the potential for the development of very large fires is expected to be up to six times as likely by mid-century (2041-2070) compared to 1971-2000 in the mountain west. 2 to 4 times in California. It hasn’t been lost on me that I’m doing another story on wildfires and the host of this podcast JD has gone through the terrifying ordeal himself after his home burned down last year. Fires that grow large so fast and going to encroach on that urban wild interface. Another bit about how infrastructure is not built for the extremes we are ALREADY seeing, let alone what may happen in the future. <a href= "https://www.wunderground.com/cat6/5th-Deadliest-Wildfire-Globally-Past-100-Years-Greeces-87-Deaths-Mondays-Fires"> Wunderground</a> <a href= "https://www.wunderground.com/cat6/Onslaught-California-Wildfire-Kills-Least-7"> Wunderground</a> <a href= "https://www.climate.gov/news-features/event-tracker/strong-winds-whip-deadly-wildfires-greece-late-july-2018"> climate.gov</a> <a href= "https://www.washingtonpost.com/news/capital-weather-gang/wp/2018/07/30/how-climate-change-is-making-disasters-like-the-carr-fire-more-likely/?utm_term=.55d1a31ac7b6"> WaPo</a> <a href= "https://www.axios.com/science-behind-carr-fire-tornado-redding-california-f77a451d-9aec-46bd-8091-acb0dd45fff0.html"> Axios</a> <hr /> <h2>Pub Quiz</h2> Taking part in the pub quiz today are: Amrita Sule and Tom Di Liberto.

Well, I have an awesome way for you to waste 90 minutes of your life. On Twitter there’s a thing called TrickyBirdID. It’s #TrickyBirdID. It’s run by Jason Ward, and you can find him at JasonWardNY. This is a daily contest on Twitter. Jason posts pictures of birds, and you try to guess what they are! It’s not always easy because the pictures may be backlit, blurry, or maybe a partial picture. It’s meant to be a challenge, and it it. He gives everyone 30 minutes to give their answers, and whoever answers correctly first wins that round. There are a total of three rounds. I was in rare form on Monday and won two of the three rounds. That last one was a white-eyed vireo, but I answered with yellow-throated vireo. Still, this is a great way for birds nerds to waste time, and for that reason I recommend hashtag TrickyBirdID on Twitter. #TrickyBirdID on Twitter <hr /> <h2>In Next Week’s Episode</h2> Dr. Grant Ballard, the Chief Science Officer of Point Blue Conservation Science. <hr /> <h2>In Closing</h2> And that concludes this episode of the Blue Streak Science Podcast.

078: Let's Get Political!
<ul> <li>Our first political endorsement!</li> <li>The Blue Streak Science News</li> <li>The Climate Lounge</li> <li>The Asshole of the Month</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Political Endorsement</h2> <h3>Dr. Shannon Hader, Democrat for the 8th Congressional District in Washington</h3> We’re coming up on that silly season again, but this time around it seems so much more urgent because so many of us failed to see the reality that we faced during the last election. Part of that reality is that the anti-science and alternative-truth segment of our society have seized power. And folks, they’re making the most of it to roll back scientific progress and education. [caption id="attachment_1215" align="alignright" width="263"]<img class="size-medium wp-image-1215" src= "https://bluestreakscience.com/wp-content/uploads/2018/07/78_350x400-263x300.png" alt="" width="263" height="300" /> Shannon Hader[/caption] However, in November we have a chance to slow them down. If we can elect candidates into Congress who understand the importance of science and critical thinking in good government then that will go a long way toward slowing down the damage to our nation and the world that is current happening unabated. So this election season the Blue Streak Science Podcast will be endorsing candidates who hold true to the values of science, equality, long-term economic progress, and the preservation and restoration of our natural heritage, both in America and worldwide. The first candidate we’re endorsing is Dr. Shannon Hader who is running to represent the state of Washington’s 8th Congressional District in the House of Representatives. Dr. Hader is the former director of the Division of Global HIV & TB at the Centers for Disease Control and Prevention. Do you want to know what the Trump administration is doing to the CDC? Their 2018 budget slashed its funding by $1.2 billion. That a 17% reduction. Dr. Hader also worked for three years as director of the HIV/AIDS, Hepatitis, STD and TB Administration at the District of Columbia Department of Health. In making her announcement Dr. Hader said, "Science-based decision-making is under assault at NASA, at the EPA and the CDC, where I felt its effects directly.” Well, we can turn this around by supporting Shannon Hader in her run for Congress. If you live in District 8 of Washington state I strongly urge you to vote for Dr. Hader in the primary on 7 August. If you don’t live in the district then you can show your support for science and good government by contributing to her campaign at: <a href="http://drshannonforcongress.com" target="_blank" rel="noopener">www.drshannonforcongress.com</a> <hr /> <h2>Science News</h2> <h3>Baby snake 'frozen in time'</h3> I have Christmas come early, but not as we know it. For most of us, Christmas presents come in boxes and nice wrapping, with little bow on top. But if you are a paleontologist then Christmas present come wrapped in amber. And things have come along a bit since Jurassic Park and John Hammond’s preserved mosquito on his walking stick since now we’re starting to get fossilized vertebrates, mostly from Myanmar. So far we’ve had a bird wing, a chick, a lizard and even a feathered dinosaur tail! This time it’s a snake. Rather tragically it is a baby snake that didn’t get a great run at life, but the upshot of this is that a lot of the animal has been preserved inside. Remains like this are like russian dolls: a fossil within a fossil, as the amber itself is a fossil of tree resin. The fact that it started life as a thick sticky tree sap is how creatures come to be trapped in it in the first place, preserved in a stone considerate enough to be transparent and so beautifully that it could make a pharaoh blush! Although the head is missing, there is enough animal left for it to be identified as a new species. (Xiaophis myanmarensis). It would have lived about 99 million years ago and appears to be a very primitive member of the snake lineage.] <a href= "https://www.bbc.co.uk/news/science-environment-44872148" target= "_blank" rel="noopener">BBC Science and Environment</a>, <a href= "https://www.livescience.com/63095-baby-snake-fossil-amber.html" target="_blank" rel="noopener">Live Science</a>, <a href= "https://www.nature.com/articles/d41586-018-05742-5" target= "_blank" rel="noopener">Nature</a> <h3>A New Geologic Age</h3> You might wonder - anyone can subdivide the time of Earth’s existence in periods entirely up their will and imagination. But that’s not how official geology works! Also, dividing the Earth’s history into eons, eras, periods and ages is much less arbitrary than you might think, and …. well… much more scientific! Go figure! So how does it work, you ask? It rocks! A new geological period is defined when significant chemical trace different from the period before is found in the rock deposits of the Earth’s crust. Deposition of such chemicals usually relates to some pretty major climatic event on the planet, which is naturally worthy of marking the start of a new geological period. The newly categorised period we live in now is called Meghalayan. The name comes from Meghalaya, a northeastern state in India, whose name means "the abode of clouds" in Sanskrit. And a rock scientists analyse from there actually made them consider updating their historical nomenclature for earth’s periods. By analyzing a stalagmite growing on the ground of a cave in the Indian state, geologists found that each layer had different level of oxygen isotopes (versions of oxygen with different numbers of neutrons). This change marked the weakening of monsoon conditions from that time. And the change they estimated was significant - between 20-30 percent decrease of monsoon rainfall, so that def qualifies as a new era, I’d say! It apparently started about 4200 years ago and some scientists think it’s still too soon to start classifying it as a new era, since it’s not well established how widespread the effects of these changes are, but if we have evidence for something for 4200 years, why not take it as rather established. <a href= "https://www.livescience.com/63103-meghalayan-age-within-holocene-named.html" target="_blank" rel="noopener">Live Science</a>, <a href= "https://www.sciencenews.org/article/living-new-geologic-age-called-meghalayan" target="_blank" rel="noopener">Science News</a>, <a href= "https://www.bbc.com/news/science-environment-44868527" target= "_blank" rel="noopener">BBC Science and Environment</a> <a href= "http://www.stratigraphy.org/ICSchart/ChronostratChart2018-07.pdf" target="_blank" rel="noopener">International Chronostratigraphic Chart</a> <h3>The Great British Butterfly Count</h3> Calling all my fellow Brits, this is an urgent call to action; Sir David Attenborough needs you. I get two stories this week and I get to mention a different Attenborough brother in each, fantastic! The legendary Sir David is calling people to take part in the Great British Butterfly Count. This is a massive citizen science survey of British butterfly populations. It’s been happening seasonally since 2010 and this year it is running from the 20th of July to the 12th of August, so it really isn’t too late to get involved. The reason that this year in particular is so important is because the conditions at the start of this year means that we should be having a bumper year for butterflies, but in case you haven’t noticed; it’s recently been very hot and very dry. Drought really isn’t a friend of butterflies and with hose pipe bans starting to be seen we could be running into tricky conditions for caterpillars. This means that this could be a really important year for monitoring how conditions affect these beautiful lepidoptera. You don’t need to be a lepidopterist to take part. If you get over to bigbutterflycount.org then they have all of the information that you need there for you to help out. It’s also a great thing to do with your kids, I intend to get out there with Matilda. But this does remind me of a question that I’ve never found an answer to, so if anyone listening can help, please get in touch. Why do caterpillars get a fancy name when all other larvae just get called a “whatever it is” larvae?] <a href= "https://www.theguardian.com/environment/2018/jul/20/sir-david-attenborough-urges-british-public-to-join-butterfly-count" target="_blank" rel="noopener">The Guardian</a>, <a href= "https://www.nytimes.com/2018/07/20/world/europe/uk-big-butterfly-count.html" target="_blank" rel="noopener">The New York Times</a>, <a href= "https://www.npr.org/2018/07/20/630848449/britains-big-butterfly-count-begins-with-david-attenborough-leading-the-charge" target="_blank" rel="noopener">NPR</a> <a href="https://www.bigbutterflycount.org/" target="_blank" rel="noopener">Big Butterfly Count</a> <hr /> <h3>Researchers use 36 years of bike race footage to illustrate Belgium's changing climate</h3> Now first I gotta say a big thanks to Amrita for alerting me on this story because I have missed it and to JD for letting me talk about it. Since I live in Belgium for 6 years now, this feels like home and I’m dying to cover interesting science from around here cause for such a small country the universities and research centers are doing pretty darn well! Anywho! To the story! Once upon a time, there was a very observing climatologist, who was also a passionate cyclist (for the record half of Belgium (the northern half, closer to the Netherlands are) called Pieter De Frenne. He works in the department of water and forest management in the Gent University. He had the brilliant idea to use archive footage of Tour of Flanders from decades back to do a comparative study on the changing climate of the region through the years. This race is one of the most regular ones - always taking place early April each year and always in the same area if not exactly the same route. So he and his colleagues went through more than 2000h of footage since 1981 until today and selected several landmarks that appear in all the footage through the years and compared them. They mostly settled for trees as these are most easily traceable/recognisable. What they noticed is that the majority of the trees in the early 80 had barely any leaves yet in early April. Compared to back then, now almost every year most of the trees were well leafed up, meaning that spring is consistently coming much earlier than just two decades ago. While this might sound like a pleasant thing, it’s not necessarily a good thing on a big ecological scale. The consistent changes in the tree part of the ecosystem has a significant effect on all other parts too - insects, birds and other animals in the area whose life is somewhat related/dependant on the trees. For migratory birds for example it can have quite dramatic effects - if they arrive to the usual destination after trees have bloomed, they might be unpleasantly surprised by the fact that their food (larvae or eggs of insects) have already matured/hatched and are either completely gone or much harder to catch and feed the bird’s hatchlings. Also, all vegetation which grows under the trees will be affected - if the tree crown is already in full bloom by the time gras, bushes and flowers show up, they might have much less access to light to be able to complete their life cycle which in turn affects other animals relying on them for food and so on and so forth - the whole ecosystem can change quite dramatically, quite fast. The scientists then went on to compare their results with other already published scientific data for the ecology of the region and established that they are in fact right and that this “out of the box” method is actually valid and working. They published their own data in the Methods of Ecology and Evolution. <a href= "https://www.cbc.ca/news/technology/bike-race-footage-climate-change-1.4736912" target="_blank" rel="noopener">CBC</a>, <a href= "https://besjournals.onlinelibrary.wiley.com/doi/pdf/10.1111/2041-210X.13024" target="_blank" rel="noopener">Methods in Ecology and Evolution</a> <hr /> <h2>The Climate Lounge</h2> Today’s story time feature in the lounge is sure to Tickle you brain. It will certainly help you tick off things on your “To-Learn” lists. It definitely won’t have you bored listening to the tick tock of the clock. This story is about ticks. I’m not a big bug person so you’ll excuse me if I don’t paint an incredibly intricate picture of what a tick is. But it’s a small arachnid whose big fame in the United States is as a carrier for Lyme disease. Lyme disease is the most common vector-borne disease in the United States and found generally throughout the Mid-Atlantic into the Northeast United States (Think Washington DC to Boston) as well as around the Great Lakes. I grew up in New York and can attest to the fear of lyme’s disease. Short story, my older brother was at a soccer tournament when we were young and I, being a dick, hid and scared him into some woods. The rest of his 10 year old boy teammates when in after him. And we never saw him again...No of course not, he walked out the other side and was back to the team in 3 minutes. But in those three minutes in the woods, 4 or 5 kids came back with ticks on them. So knowing what’s going on with ticks is sorta important. Lyme disease can be a debilitating bacterial infection affecting the joints, heart and nervous system. Enter Nathan Nieto and his lab at Northern Arizona University. From August 2016 to January 2017, his lab ran a pretty cool deal. If you found a tick, you could send it to his lab and he would give all the info you need on the little evil thingie (I’m adding irrational personal feelings here so don’t yell at me…). For tick research, they normally get 100 ticks at a time by pretty basic methods like dragging a piece of fabric behind a truck, any adrenaline loving ticks hop on.. TO THEIR DOOM for science. For this public science effort, they budgeted for 2400 ticks, yet received nearly 16,000! They just published their results in PLOS One. Dr. Nieto’s lab were sent ticks from 49 states (no Alaska) and Puerto Rico. Once received they tested them for 4 pathogens including Borrelia burgdorferi, the bacterium that causes Lyme disease. They found some rare ticks but also ticks capable of carrying Lyme disease in 83 counties where they hadn't been recorded before.This really shows the power of citizen science as tick research can be incredibly difficult. A study of this size could never have been done without public involvement. How does this tie to climate change? Ticks occur on earth. Moving on… No really, ticks rely on warm temperatures to live. As temperatures warm, as winters shrink, as spring comes earlier and fall lasts longer, ticks can be out there for longer. Plus, warmer temperatures can enhance the rate at which a baby tick becomes fully developed. Tick development rates have increased by two times in the US and 5 times in Canada. Not surprisingly, the rate of Lyme disease has doubled since 1991, from about four cases per 100,000 people to eight. And where does the name come from, since I’m sure you’re wondering? Well Lyme Regis in southern England, indirectly. The first case diagnosed as lyme disease occurred in Old Lyme, CT, named after Lyme Regis. Not to go off too far on a tangent but it’s interesting so here we go. The northeast US is scattered with town names in reference to England (I grew up in a town called Smithtown inNY) but things get really weird near new york as english settlers ran into dutch settlers who founded New Amsterdam (after stealing land from the native population) which later became New York after the dutch lost to the english in 1674. But the dutch left a legacy in New York as many neighborhoods still bare dutch names. Brooklyn, Bronx, Coney Island, Harlem are all dutch. And even common words used in the US like boss come from the dutch. Ever wonder why Americans call them cookies and the english call them biscuits. THE DUTCH. Fascinating stuff. Tangent over. <a href= "https://www.npr.org/sections/health-shots/2018/07/12/628491294/researchers-study-thousands-of-ticks-collected-by-the-people-they-bit" target="_blank" rel="noopener">NPR</a> <a href= "https://www.cbsnews.com/news/ticks-that-carry-lyme-disease-are-spreading-fast/" target="_blank" rel="noopener">CBSnews</a> <a href= "https://www.sierraclub.org/sierra/climate-change-tick-s-best-friend-lyme-disease" target="_blank" rel="noopener">SierraClub</a> <a href= "https://www.vox.com/science-and-health/2017/6/6/15728498/lyme-disease-symptoms-rash-ticks-global-warming" target="_blank" rel="noopener">VOX</a> <hr /> <h2>Asshole of the Month</h2> Donald Trump, President of the United States In 1962 when I was a year old, Rachel Carson published her landmark book on environmental science called “Silent Spring”. That lit a fire in the American consciousness about the environment. In the 1960’s the air in our cities was awful. The Cuyahoga River in Cleveland caught fire in 1968. Seriously, it caught fire! I remember hearing about how birds of prey were disappearing because of pesticide pollution. In particular, the pesticide DDT (or more accurately its breakdown product DDE) would move up the food web getting more concentrated with each step, until it was consumed by apex predators such as California Condors, ospreys, and peregrine falcons. The effect of DDT on these raptors was that it caused them to lay eggs with very thin shells, or no shells at all. Those thin shells would crack under the weight of incubation. And this caused their populations to plummet. The iconic bald eagle was nearly extinct in the contiguous states in the 1960’s and 70’s, as was the peregrine falcon and many other birds. As a result of increased environmental awareness we made real progress with the Clean Air Act of 1970, the Clean Water Act of 1972, and the Endangered Species Act of 1973. <h4>The Endangered Species Act.</h4> This is the single most important piece of legislation in the United States for conserving biodiversity and slowing down the extinction of species. The Act was passed in 1973 with overwhelming bipartisan support (the House voted 355-4 in favor of the law), and it was done so at the urging of a Republican president, Richard Nixon. How times have changed. Since its passage, the Endangered Species Act has helped reverse the impending extinction of species from the magnificent Grey Wolf to the Schaus’ Swallowtail Butterfly of the Florida Keys. Still, over the decades the law has been criticized by big business and agricultural interests who feel that the Act limits their ability to generate a profit, and to do whatever the want with their property. Enter the Trump Administration. Last week they proposed to severely restrict the scope of the Endangered Species Act. This led to Congressional hearings on the Act and has raised the alarm nationwide that one of the nation’s best ideas is about to be eviscerated. Consider this: <ul> <li>A 2011 Harris Poll showed that 84% of Americans support the Endangered Species Act, with Democrats having the strongest support at 93%.</li> <li>64% of Americans believe it acts a safety net and a balanced solution to save wildlife, plants and fish that are at risk of extinction.</li> <li>63% of Americans believe decisions about whether to remove the Endangered Species Act’s protections should be based on science, and not politics.</li> <li>92% of Americans agree that decisions about wildlife management and which animals needs protection should be made by scientists, not politicians.</li> </ul> Seriously, 92% of Americans don’t agree that the sky is blue on a sunny day! Yet the same number actually agree that this is a decision that should be made by scientists, and not politicians. There are some issues like gun control and reproductive rights which are terribly partisan, but the Endangered Species Act is not one of those issues. So, for going against the will and interest of the American people, and for selling out our country’s natural heritage to special business interests for a profit, Donald Trump, you are the the Blue Streak Science Asshole of the Month. <hr /> <h2>Pub Quiz</h2> Joining us today are the Chris MacAlister, Nevena Hristozova, and Tom Di Liberto. Here’s how it works. I ask a science question and our team of science dweebs offer up their witty answers. <ol> <li>Remember the online name search last year for that research ship? The consensus was Boaty McBoatface, but they decided to name it after Sir David Attenborough. There’s another naming contest going on in the science world...what’s it for?</li> <li>This past week a paper came out that suggests Neanderthals could do something the rest of us can do quite easily. What is that?</li> <li>It was announced this week that a fossil of Bigfoot has been found. But that’s just what they’re calling it. What kind of animal was it really?</li> <li>What gelatinous pink species is invading the waters of the American Pacific Northwest?</li> <li>A Chinese tree shrew loves to eat this food that most animals avoid, but oddly enough, many humans crave. What food is it?</li> </ol> For the answers to today's Pub Quiz just have a listen to the podcast! Ain't we sneaky that way? <hr /> <h2>Recommended by The Team</h2> Tom: It’s not science but it’s still fascinating. If you are curious to learn more about the Dutch influence on New York City and on thus on the United States, I highly recommend reading The Island at the Center of the World by Russell Shorto. Even as a New Yorker, the history of New Amsterdam is glossed over in our history books, but the legacy of dutch culture, you could argue, has given New York City the identity it has to this day as a cultural melting pot. Plus, it’s crazy to see a place as terraformed as Manhattan depicted as it likely was to Native Americans when the first European colonizers reached it. <hr /> <h2>Where Have We Been?</h2> Chris: I’ve been to a roundabout in Chester. I little bit random I’ll grant you, but I’m afraid that it gets no less random when I say that I went there to play a gig to a guy on a treadmill! What’s actually going on is that a guy called Steve Hughes is on a mission to raise funds to build the UK’s first <a href= "http://www.gardensbythebay.com.sg/en/attractions/supertree-grove/facts-and-figures.html" target="_blank" rel="noopener">supertrees</a>. They have some magnificent ones in Singapore. They are essentially big hollow metal trees and they can be used a frame for plants to grow up, they create habitats for all manner of flora and fauna in the middle of city, returning some biodiversity to places where it has been all but eradicated. The ones that Steve are trying to fund are nowhere on the scale of Singapore but they will also provide an space for people to come and learn about the trees and what they do, as well as containing weather stations. So far Steve has run 7 marathons in 7 days in 7 countries and last weekend he ran 100km in 10 hours on a treadmill. He made an event of it, this why I was playing. If you want to know more or support him the you can check him out on <a href="http://chestersupertrees.org" target="_blank" rel= "noopener">chestersupertrees.org</a>. Nevena: Just coming from a panel discussion on cities and urban life beyond growth - how can cities be drivers of change in production practices and consumption patterns. Tom: If you find yourself in Washington DC you might catch me in an improv comedy show with the Washington Improv theater. JD: I attended another lecture at Bodega Marine Lab. This one was titled “Saviors of the reef? Context-dependent control of algae by coral reef fishes”. The speaker was Mike Gil, who is a postdoctoral researcher in Environmental Science and Policy. He is working on coral reef ecology projects in Thailand. <h2>Where Are We Going?</h2> Nevena: Going to a bi-weekly civic hack night - organised by the Civic Hack lab BXL. This edition will be about InfluencAir - citizen science project to measure air quality in Brussels. Never been part of a citizen science project so I’m very curious and excited to see what’s it about! Tom: So on Saturday August 4th at 6pm, my science improv comedy team The Hypothesis will be performing at the 12th annual Baltimore Improv festival. We’re a team made up of all different types of scientist and science enthusiasts who like to walk on the funnier side of science and the sciencier side of comedy. JD: It’s back to the Bodega Marine Lab for me. “Phototaxis and phototropism in symbiosis” by Dr. Shawna Foo of the Carnegie Institution for Science in Pittsburgh, Pennsylvania. <hr /> <h2>In Closing</h2> I’d like to thank our newest Patreon supporter, our friend Sam Danby from Norway!

077: Michael MacFerrin, Ph.D. - Glaciologist
<ul> <li>Conversation with Michael MacFerrin, Research Glaciologist</li> <li>Science News</li> <li>The Climate Lounge</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News with Nevena Hristozova and Chris MacAlister</h2> <h3>An Origin of Cosmic Rays Discovered</h3> In a galaxy far far away… For real though - it’s really far - 4 billion light-years away. My calculations show that with the current tech for space flight we have, we could get there in 76.32 trillion years so it is freaking far! But anyway, the point is that this galaxy is a blazar - a type of an active galactic nucleus with a relativistic jet directed very nearly or directly towards Earth. These jets are essentially ionized matter traveling at nearly the speed of light. Relativistic beaming of electromagnetic radiation from the jet makes blazars appear much brighter than they would be if the jet were pointed in a direction away from the Earth. So far we knew that blazars are powerful sources of emission across the electromagnetic spectrum and are sources of high-energy gamma ray photons. Now though we know something new - because that’s the whole point of science! It appears, according to the latest data coming from the so called The IceCube Collaboration, that this blazar galaxy is a source of high-energy neutrinos - one of the most elusive particles in the universe! Their article was published in Science under the title Multimessenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A. The astrophysicist Francis Halzen of the University of Wisconsin–Madison, a leader of IceCube, himself said that so far no one was able to pinpoint the source of this type of neutrinos. By basically tracing the trajectory of the heavy neutrinos detected in the IceCube, the scientists could determine its place of origin somewhere close-by Orion. In intergalactic distances, this is probably like searching for a sand grain in all the oceans on our planet. But employing a bunch a telescopes including the Fermi Gamma-ray Space Telescope, they’ve found the blazar TXS 0506+056 (I’m so naming my firstborn like this!). And the best part is that we were able to trace this neutrino back to home because it is essentially so elusive! Neutrinos (as their name shows) have no charge so they travel through the universe without much effect from other matter in it. Exactly this reluctance to interact with other matter is the reason why generally neutrinos are so hard to detect and study… It’s a beautiful catch 22 in this case! <a href= "https://www.sciencenews.org/article/high-energy-neutrinos-blazar-icecube"> Science News</a>, <a href= "https://www.bbc.co.uk/news/science-environment-44786125">BBC News</a> <h3>Cancer Fighting Cancer Cells</h3> They say that you can’t fight fire with fire, but this isn’t true if you’re smart about how you use your fire. Controlled burning is best measure available for controlling wildfires. So could the same be said for cancer? Can you have a little bit of controlled cancer to protect you from the main article? Maybe so, if you’re clever enough. It appears that Clemens Reinshagen and a team at Harvard are clever enough as they appear to have pulled this off, in mice. They have done this by turning cancer cells into double agents. Cancer cells loose in the bloodstream can detect and home in on other tumours and this is the key skill that the team use. Once our double agent cancer cells have infiltrated the tumour, they commence the next stage of their operation. They release a protein that triggers cell death in the cancer cells; that is, all the cells except our double agents. CRISPR based technology has been used to alter these cancer cells to provide them with protection, so that they can continue their job. But even once the job is done, you’re still left with a patient full of cancer cells, which is clearly less than ideal.

This is a long time ago! Much longer than we thought the early hominids have ventured out of Africa. 2.12mln to be precise - precision is important! At the same time, a giant rodent weighing nearly 700 kg used to live in South America, just to give you a perspective how different the world was back then. Nonetheless, there were already established members of the genus Homo who decided that Africa is old news and they went travelling, reaching as far as China. This is known now thanks to some stone tools unearthed at China’s Shangchen site. They were dated to roughly quarter million years before what was previously thought to be the oldest evidence of Homo genus on the Eurasian continent. Unfortunately, no hominid fossils have ever been discovered from this period in the site. Until they do find similarly dated hominid fossils in the area, we’ll not know for sure if the representative was a Homo erectus or an earlier hominid.] <a href= "https://www.nature.com/articles/d41586-018-05696-8">Nature</a>, <a href= "https://www.sciencenews.org/article/shangchen-stone-tools-put-early-hominids-china-earlier"> Science News</a> <h3>Otzi’s Last Meal</h3> I reckon that you guys should all come over to mine for a big Blue Streak Science get together sometime. I’m already having some ideas for what I’m going to cook you. We could start off with some cereal, followed by a nice piece of venison, and I’ll serve that with some poisonous fern. How does that sound? You know what? I’m thinking that maybe cuisine has come along a bit in the last 5,300 years. This is the story that the stomach contents have been analysed of a man who was naturally mummified in about 3,100 BCE, a man known as Otzi the Iceman,. His diet of cereal, Ibex and deer was probably pretty standard for him. It’s unlikely that treated himself to a lavish last supper as it looks like he was killed in a surprise attack. With that in mind, the really confusing part of these findings is the poisonous ferns. Why would he be eating poisonous plants? The leading theories that the team have is that it may have been medicinal, to help combat internal parasites, or that he may have wrapped his other food in it leaving some toxic spores behind to be consumed. The team don’t know if the food that Otzi ate was fresh or not, so maybe wrapping it in something toxic could help prevent spoilage, or to ward off scavengers. Although, considering the amount of smoking and recreational substance abuse that still goes on today, maybe it was just what all the cool kids did back then. He may not even have known that it was toxic. Either way, the amount of detail we are getting about Otzi, over 5000 years after he died, is incredible. And as if this isn’t amazing enough, the next objective is to use this information to try and recreate what Otzi’s gut microbiome may have looked like, providing another way to peer back in time and see what his life have been like.] <a href= "https://www.scientificamerican.com/article/heres-what-oetzi-the-iceman-ate-before-he-was-murdered/"> Scientific American</a>, <a href= "https://www.livescience.com/63044-otzi-mummy-last-supper.html">Live Science</a> <hr /> <h2>The Climate Lounge</h2> <h3>We’re not getting any Younger (Dryas) over here!</h3> Sometimes the news just makes me want to go back to a simpler time. A time without the internet, meddling and farcical meetings. I’m not talking the 20th century either. I’m thinking even farther back. About 13,000 years back when the human population was less than 1 million, and boy did the environment think that was swell, and things were a bit chillier. The planet was just coming out of an ice age. And that meant temperatures were on the upswing along with oceans. It was a wonderful active time…. Geologically. Painfully slow changes humanely. Then…. All of a sudden (and I don’t mean SUDDEN geologically, I mean human sudden like several decades suddenly), the northern hemisphere was plunged back into a colder climate that lasted for a thousand years. A well known abrupt climate change whose cause has been studied and questioned and fought over (scientifically so it’s friendly) for years. It’s what is known as the Younger Dryas, named for a flower whose official name is latin mc-latinface… or dryas octopetaia. Either one. Anyways, recent research led by the Woods Hole Oceanographic Institute or WHOI has a new claim as to what happened. They took sediment cores in the eastern Beaufort sea near where the Mackenzie river empties into the ARctic Ocean which also happens to be near the border of the Yukon and Yellowknife territories. By looking at oxygen isotopes in the shells found in the cores, they determined that a massive glacial flood occurred there near the time of the abrupt Younger Dryas. This truly humongous flood would have dumped tons of fresh water into the Arctic that the researchers say would have made its way into the Atlantic Ocean. Where did the water come from? Melting glaciers. Specifically the Laurentide Ice sheet. As it melted it formed massive lakes including Lake Agassiz, a ginormous lake in the middle of modern day canada.. But as the ice sheet melted, what kept those lakes in place suddenly disappeared, allowing them to empty. Now for awhile, the water flowed south through the Mississippi. But eventually, it shifted to flow north. Some researchers have thought it emptied through the St Lawrence seaway into the Atlantic. What makes this research novel is that the meltwater instead flowed north into the Arctic. Now, not all scientists agree...they never do… but regardless of where the meltwater entered the Northern atlantic/Arctic, it’s what it does afterwards that’s interesting. Why does that matter? Well it makes more sense as to the mechanism that actually caused the cold change. All of that freshwater slowed or stopped the giant Atlantic ocean conveyor belt known as the “Atlantic meridional overturning circulation” (or AMOC) which brings warm water to Europe. Normally, that conveyor belt of water becomes saltier as it moves north, becoming denser and sinking. The injection of freshwater in the Arctic/North Atlantic disrupts this by freshening the water and not letting it sink. This slows down the conveyor belt which means less warm water to Europe and a plunge into coldness. Why do we care now? Well there is a HUGE amount of freshwater locked into Greenland. As it melts, it is also depositing fresh water into the North Atlantic, albeit much slower than the sudden Younger Dryas event. However, there is research that says the AMOC is slower than it used to be. While scientists don’t think a shutdown is imminent, past events like the Younger Dryas abrupt cooling can give interesting insight into just how our climate system works, especially if we stress it in certain ways. The climate is super duper complex and what may seem like a small regional climate change somewhere can easily snowball (pun intended for this story) into something much bigger, like hemispherically bigger. Let’s also keep that thought in mind whenever we talk about geoengineering. <a href= "http://www.whoi.edu/news-release/following-the-fresh-water">WHOI</a> <a href= "https://www.washingtonpost.com/energy-environment/2018/07/11/scientists-may-have-solved-huge-riddle-earths-climate-past-it-doesnt-bode-well-future/?utm_term=.6241e0bec71e"> WaPo</a> <hr /> <h2>Interview with Michael MacFerrin, Glaciologist</h2> This past winter I had the privilege to chat with Michael MacFerrin, glaciologist, and Ph.D. candidate at the University of Colorado Boulder. We talked about his work and discoveries on the Greenland's immense ice sheet. Science is hard work, folks! But the rewards and experiences last a lifetime and beyond. Join us as Mike shares his incredible experiences from this frozen wilderness. <hr /> <h2>Pub Quiz</h2> All in favor of doing the Pub Quiz say “aye”! The ayes have it! Joining us today are the incredibly intelligent Nevena Hristozova, the immensely imaginative Chris MacAlister, and the intermittently inclement Tom Di Liberto. Here’s how it works. I ask a science question and our team of incomprehensible intellectuals initiate their ingenious answers. It’s all fun and games until someone loses an eye. <ol> <li>What animal possesses the most massive eyes?</li> <li>Swiss physician Adolf Fick is credited with fitting the first what in 1888?</li> <li>What is the world’s most common eye color?</li> <li>This eye color is in what part of the eye?</li> <li>When you go to an ophthalmologist for an eye exam, you are often asked to look at a chart that has rows of letters in decreasing sizes, with a very large "E" at the top, followed by other letters.

It's a collaboration between the Flemish universities and includes half day plenary talks on scicomm topics and 2 or 3 days of workshops on various scicomm skills. I was one of the six reps of universities representing my university as sort of a scicomm role model (yeah baby). So we had a discussion on what's scicomm for us all, what it gives us and why we do it, what's our fav media for scicomm and apparently I stirred the audience by saying that I myself am my fav media because I just love the most to sit and talk with people about science. It was extremely cool and it felt a great honor to have been part of this. <a href= "https://sgseventcenter.webex.com/mw3300/mywebex/default.do?nomenu=true&siteurl=sgseventcenter&service=6&rnd=0.259603886242068&main_url=https%3A%2F%2Fsgseventcenter.webex.com%2Fec3300%2Feventcenter%2Fevent%2FeventAction.do%3FtheAction%3Ddetail%26%26%26EMK%3D4832534b00000004cf3ad56ff9c182086c30620384b8675da1e2684a64d0201bb8a33edb6ff59aa3%26siteurl%3Dsgseventcenter%26confViewID%3D100959156532413720%26encryptTicket%3DSDJTSwAAAAQyFdS3-yzIOuSqne86gA4Hm5HLFZqBb3kCgpJTkAcc-w2%26" target="_blank" rel="noopener">SGS Food Webinars</a> Chris: I’ve been to family wedding in Cornwall, which is limited in its level of scientific interest if I’m completely honest. But whilst I was there I was talking to by wife’s cousin who is a tattoo artist. This conversation included tattoos, how training tattoo artists need to practice on themselves and the inevitable spectre of unwanted or regretted tattoos. This compelled me to go into science communication mode and share the findings of a surprisingly recent study on why tattoos last for as long as they do, considering how quickly our skin gets replaced. The key is our immune system. The tattoo ink gets locked inside white blood cells that try, in vain, to destroy the ink. This actually ends up preserving them inside and as each immune cell dies, a new one takes its place to continue the preservation. The useful thing about knowing this is that immunosuppression can be used to aid the tattoo removal process. Tom: I’ve been taking a 2.5 year old to gymnastics classes where they attempt to get a bunch of toddlers to play group games together. My toddler disagrees and immediately makes a run for the balance beam. In good news, he has great balance and is seemingly indestructable. In bad news, for the other kids, he tends to bounce off everything even other children. Those kids arent so lucky. <h2>Where Are We Going?</h2> Nevena: On the 19th of July, Thursday I'll be attending an online seminar by SGS. It's a Food safety webinar entitled 'How to Improve Food Authenticity, Traceability and Safety using Next Generation Sequencing'. If it's not too late for our listeners with interest in knowing how can authorities can use latest technologies to ensure that what we eat is what the label says. It's at 10am Central European time @sgseventsenter webpage. <hr /> <h2>In the Blogosphere</h2> Nevena: If I may - an episode of my other podcast, the one I actually produce is just out - it's only our 4th and it's with guests from an account on Twitter called Latino labs promoting diversity in academia. You can listen to it on my blog incubatorium.eu of the right hand side directly or anywhere you catch your podcasts if you search for the Scicomm JC podcast. Chris: In addition to recent posts about whether dogs can smell fear and how to recreate radiation using a skipping rope. This week, on Matilda’s Lab I’ve finally dealt with a subject that I’ve been meaning to for a long time: Uncertainty. One of the big misunderstandings of people who question modern science is that we don’t prove things; only Mathematicians can do this, instead; all we can do is to minimise our uncertainty about things and accept that what we know can change depending on where the evidence takes us. Ultimately, we are in a non-ending war against ignorance. Ignorance is our default state, so if you (like so many people) are fearful or ashamed about your ignorance, don’t be, we all have it. Instead, get out there and do something about it!. <hr /> <h2>In Closing</h2> Thanks to Michael MacFerrin for sharing his amazing work in the frozen (but thawing) north.

076: Mariana Di Giacomo - Paleontologist
<h2>On This Week’s Show</h2> <ul> <li>We get an inside look on fossil restoration and paleontology with Mariana di Giacomo of the Smithsonian National Museum of Natural History</li> <li>Science News</li> <li>The Climate Lounge</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News with Chris MacAlister and Dr. Amrita Sule</h2> <h3>Wetlands Protection Rule put ‘too much emphasis’ on science, Trump officials complain</h3> It’s time for the continuing adventures of the Trump administration and their valiant efforts to protect you from the scourge of the environment and its evil plans to keep you healthy and alive! As scientists we shouldn’t make assumptions about things but I reckon it’s pretty safe to bet that if you’re taking time to this science podcast then you probably aren’t a fan of White House at the moment. So I’ll try to avoid preaching to the converted because there is some other interesting stuff going on. The broad picture is this. The United States has a Clean Water Act. It’s a law that gives isolated wetlands and waterways automatic federal protection. Whilst this may be one of the few environmental protection measures that Trump isn’t scrapping, his administration argues that the interpretation of this law is not in keeping with its wording. To be fair to them, they have a point; the law is impressively vague. The Act says it should apply to "navigable waters of the United States". “What do they mean by that?” you may ask. The Act defines them as "waters of the United States." I’m sure glad that they clear that up! The Supreme Court has attempted to decide what that phrase means 3 times and how far have they got with this? They’re split. To cut a long story short; the Obama administration interpreted the law in a way that not only protected the areas in question but also protected the waters that feed into these waters. After all, what’s the point in putting your valuables into a safe and then leaving the door wide open? But it is this interpretation that the White House is questioning stating that Obama’s Environment Protection Agency (the EPA) put “too much emphasis on science”. Ken Kopocis, who lead the agency at the time, said that "It's baffling for a science-based agency to say that they relied too much on science" and I can see his point. You wouldn’t accuse Roger Federer of paying too much attention to Tennis. But the reason why this accusation is being made is because EPA should rely both on science and law when developing regulation. The defence of the EPA is that, with such a vague law to work with, what’s left to rely on other than the science. For me, the really worrying thing isn’t that this argument is being made, it’s why is this argument being made? Why would you want to remove protection from these areas; what possible better use could they put it to? Don’t go all Big Yellow Taxi on me America, it may not be paradise but we don’t need another parking lot! <a href= "http://www.sciencemag.org/news/2018/07/obama-s-wetlands-protection-rule-put-too-much-emphasis-science-trump-officials-argue?rss=1"> Science</a> <h3>Human Implants Invaded by Microorganisms</h3> This story definitely makes me think of the time when I had a screw and a rod in my ankle due to a fracture. But who knew that when these implants were removed a year later they had likely become home to number of microorganisms found in the human body. Implants like screws from joints, pacemakers, or plates from skulls when first implanted are completely sterile – which makes sense because you don’t want any infection. But recent studies showed that, once in place, they start being colonized by fungi and bacterial species which naturally occur in the body. Previously there have been studies on microorganisms on implants surrounded by infected tissue. However, this is the first time studies have been carried out on implants from people with no such complications. This study, which was carried out at Costerton Biofilm Center at the University of Copenhagen, looked at around 100 implants from infection free patients. They also looked at implants from patients who were due to have them removed, as well as from deceased patients. The group found that about 70% of implants were covered with microorganisms. These are not harmful as they had not attacked by the body’s immune system. This is pretty cool because although it is be well known that human bodies are home to microorganisms it has been thought that our tissues and blood are free of them. But given this observation that might not the case, as one possibility is that the bacteria and fungi reach the implants via blood stream. More studies need to be done to answer questions like – What is the role of these microorganisms who make these implants their home OR Does this colonization by good bacteria/fungi prevent infections? <a href= "http://sciencenordic.com/human-implants-are-invaded-microorganisms"> ScienceNordic</a> <h3>The End of the Road for Kepler Space Telescope</h3> One of our great eyes in the sky is about to close for the last time. The Kepler Space Telescope is about to run out fuel. Supplies have got so low that it has been put into hibernation until the start of August when it gets its slot on the Deep Space Network. At this point it will awake, use the last of its fuel to point its antenna toward Earth, transmit its final message, and then it will be goodnight Kepler. So here at Blue Streak Science, we’d like to take this opportunity to celebrate Kepler and all that it has achieved. This NASA mission was named after Johannes Kepler, a 17th century German mathematician, astronomer and astrologer (no one’s perfect). He formulated the laws of planetary motion and was one of the giants whose shoulders Newton, in his own words, so famously stood upon. Kepler was launched in 2009, charged with the task of discovering Earth sized exoplanets. It cost six hundred million dollars, and do you want to know what you get for that kind of money? One instrument: but, oh what an instrument; it’s photometer can monitor the brightness of 150,000 stars at once, watching for those characteristic dips in radiation caused by a passing satellite. So how did this one trick pony perform? Well its earthbound predecessor, the High Accuracy Radial Velocity Planet Searcher, has discovered 134 exoplanets but it’s had a five year head start. Kepler’s total is 2,512 with 5,011 candidates still awaiting confirmation. Kepler’s legacy will be the confirmation that exoplanets are very common. And this has massive implications for the greatest question of humanity; are we alone in the Universe? Because the more planets that there are out there, the more chances there are that something may be living on one. But the search does not stop here, TESS the Transiting Exoplanet Survey Satellite, launched in April of this year (as was so expertly covered on this podcast) and should have started collecting data last month. It is expected to discover another 20,000 exoplanets, which is great news for anyone looking for work in exoplanet astrology. You guys are gonna be busy! <a href= "https://www.space.com/41099-kepler-space-telescope-hibernation.html"> Space.com</a> <h3>Raptors of a Feather</h3> Let’s go back in time guys. We have a story from the Jurassic World. So, who is it this time? The RAPTORS – my personal favorites, who have made appearance in the entire Jurassic park franchise yet. Now in the movies we have seen how these intelligent Velociraptors work together and hunt in packs. But did they do that in real life as well?? Velociraptors as they have been called were similar to another animals called Deinonychus. Bonebeds of Deinonychus surrounding bones of herbivores have indicated that they worked in packs to hunt the prey however this notion has been questioned over years. But there is another line of evidence, which comes from their tracks which also indicates the same at least in part. In 2008 paleontologists described that velociraptor –like animals walked side by side for a time. The imprints discovered had the signature of two-toed imprints - with the killing claw held off the ground, indicating that they belonged to deinonychosaurs. And just this year another set of deinonychosaur tracks indicating signs of similar interaction was found. These tracks are among the aggregation of 300 dinosaur footprints in the Early Cretaceous rock of eastern China. There are four trackways with 15-18 foot prints and alongside each other in the same direction. Theses footprints initially look single toed but then if you think of modern ostriches – who have two toes but them most of their body weight rests on one toe – making an imprint look like single toed. These footprints were pretty small about 10 cm in length thus likely made by a smaller animal. The most important thing that stood out was that these tracks are very close to each other and go in same direction. At one point you see that one track crossed the other and that one Deinonychosaur was lagging behind but more or less they followed same path. Now, from these tracks it is difficult to say if this particular pack was hunting or just out on a stroll. Well I guess for this moment back in time, birds of feather were just flocking together. <a href= "https://blogs.scientificamerican.com/laelaps/raptors-of-a-feather/"> Scientific American</a> <hr /> <h2>The Climate Lounge</h2> Thanks JD! It’s summer in the climate lounge, so we’re going to talk about summery things. Cold drinks with umbrellas. A relaxing day at the beach. And scorching temperatures that have caused horrible things across North America and serve as a scary reminder at what may be not a rare event come the next 50-100 years. Things jumped up a notch there at the end huh? Yeah, I know. Here in the climate lounge we go from 0 to 50….celsius REAL QUICK. So over the last several weeks a giant heat dome has sat itself in the upper troposphere over much of North America. This has led to sinking, warming air, and a lack of clouds allowing for the summer sun to simply bake the continent. Now it hasn’t done all of this in the same place at the same time. The focus of the dangerous heat has shifted across North America (and even been located in Europe). Chris: [Tell me about it!] First, temperatures were hot over eastern North America. Temperatures in Washington DC didn’t drop below 80 for a couple of days. But the scarier stuff happened farther north in Canada. The hot temperatures in Quebec have led to at least 54 deaths, 24 of which were in Montreal as scorching temperatures descended on a region that is simply not used to that sort of heat. Many of those who died were older and lived in places without air conditioning. Temperatures in montreal stayed near 35 C for nearly a week, the longest period of warmth since 1965. Long lasting heat and warm nights are a very bad combo for the elderly and young. The body simply has no time to recover. Moving west, the heat dome led to some frankly startingly temperatures out in California. On July 6, the temperatures set all-time recor in 6 locations in southern California. Including 117 in Van Nuys, 118 in Riverside and 111 at UCLA. Downtown LA only hit 108 a daily record that beat the old one by 14 degrees. According to the US’s National Weather Service, it hit 120 at Chino which would be the highest ever temperature recorded by an automated site in the region of southern California (coastal or valley). That’s absurd. It’s sorta hard to explain why because my jaw literally dropped when I first saw that and has remained that way. I mostly subside now on bugs that mistakenly fly into my mouth. It’s a living. What makes this nuts is that California normally sees its hottest temperatures in September when dry winds called the Santa Anas zoom down the mountains and warm as they compress, leading to hot temperatures. To be setting temperature records like this in early july is again, absurd. So it was hot. Who cares? Its weather right NOT climate. That’s sorta missing the point. But listen to an expert Michael Wehner of Lawrence Berkeley National Laboratory, "[i]n probabilistic terms, climate change increased the chances of the heat wave by about 20 to 50 times," adding that there is at least a 99% likelihood that human-induced climate change "<a href= "https://doi.org/10.1016/j.wace.2018.03.001">increased the severity of this heat wave</a>." Climate change is affecting temperatures now. It’s beginning to show its weather cards on the table… As temperatures continue to warm, events like this will become more and more common. And while some folks who are used to hot temperatures may be thinking Psht I can handle that, the last two weeks show some pretty big vulnerabilities. During the heat wave in California, electricity demands skyrocketed and power went out for 12-24 hours. Yes. It was 115 degrees in a place that normally gets hot. And the power still went out. But even scary is what happened in Canada. Simply put, it’s a region not used to the type of heat wave that may be common in 50 to 100 years. And because of that, many residents simply don’t have the technology that people more used to the heat do, like air conditioning. And when that happens, sadly people die. Now it will get hot every summer. It is summer after all. But every year we see glimpses of what in the future we may see as normal. And that could mean drastic changes to the way people, cities and regions exist. Now that is not fatalistic. I’m not saying we’re doomed. What I’m saying is, let’s acknowledge what we are seeing, and take steps to make it not so bad. Oh and maybe think about who among us will be most affected the quickest thanks to climate change.

On our first night at the campsite I took my dog, Cassini, for a short walk before the sun completely set. I’m so glad that I did as I soon became aware that we were not alone. All around me, darting through the air were bats, pipistrelles. “Wow” I thought, “Matilda would love this!” And then responsible parenting thoughts kicked in: “Agh, we’ve just put her down to sleep”. But sod responsible parenting, there’s bats everywhere, so I went to get my daughter out of bed. Now I should probably explain at this point that Matilda LOVES bats. Spooky moods in kids TV are ruined because every time a colony of bats emerge unexpectedly Matilda is delighted! We are so lucky to have one of the best zoos in the UK on our doorstep, Chester Zoo, and Matilda’s favourite place in the zoo is the bat cave, where Rodrigues Fruit bats and Seba’s short-tailed bats are free to fly around you, and possibly shit on you. So the expression on Matilda’s face as the pipistrelles started to emerge before her eyes is something that I will never forget. It was one of those moments that reminds me exactly why I do science communication, because there is no greater spectacle than the wonder of nature and no greater feeling than sharing that with someone. <h2>Where Are We Going?</h2> JD: Going to a lecture at Bodega Marine Lab in stunningly beautiful Bodega Bay, California.

075: Chris Ryu - Dorset Science & Technology Centre
Today we begin our pivot towards doing more interviews on the podcast. And we could not have chosen a better person to talk with than our good friend and science outreach superstar Chris Ryu. We had a terrific time talking about the Dorset Science & Technology Centre and the Atom Club. Chris' passion is in science, technology, and coding and his mission is to share this with children and adults in some of the more rural areas of southern England. We applaud the hard work and dedication of everyone involved in this important science outreach development. <h2>On This Week’s Show</h2> <ul> <li>Interview with Chris Ryu of the Dorset Science and Technology Centre</li> <li>Science News with Sophie McManus and JD Goodwin</li> <li>The Climate Lounge</li> <li>Pub Quiz</li> </ul> <hr /> <h2>Science News with Sophie McManus and JD Goodwin</h2> <h3>Crow vending machine skills 'redefine intelligence’</h3> Last week a new study published in Nature Scientific Reports revealed further evidence for their cognitive abilities, and shows that these so-called “bird brains” can memorize tool shapes and even recreate them from memory. The subject of the research is the New Caledonian crow. They’ve been studied for quite some time now. In their native habitat they’ll fashion hooks to very precisely snag grubs and other tasty treats from holes and crevices. Where does this behavior come from? Are they just copying other crows without thinking about it? Is this a hard-wired behavior that all of these crows possess as instincts? It also could be possible that these crows are memorizing tool designs, and recreating them. This research was led by Dr. Sarah Jelbert, a post-doctoral research associate in psychology at the University of Cambridge. Dr. Jelbert and her team designed this experiment to see if this behavior, this cumulative cultural evolution, is happening with these crows. They had 8 subjects, and the first order was the train them to recognize what a proper tool looks like. The one that’ll “do the trick”. In this case the right tool for the job was a correctly sized piece of paper. The experimenters offered the crows differently sized pieces of paper that they could use on a specially made vending machine...one that dispensed meat. The crows had to figure out if the larger pieces of paper would release the delicious treat, or a smaller piece of paper. When the correctly sized paper was put into the slot a hidden experimenter opened the hatch and a tasty treat would come rolling out. So the birds were conditioned to understand which size of paper would do the trick. Here’s the best part. The crows were then given larger sheets of paper. Instead of giving up they used their gray matter to figure it out. The crows began to use their bills and talons to tear and shape the paper into the properly sized tools. They were trained to know what sized tool was needed. This information had to be stored as memory. Then they had the ingenuity to take that information and create the right tool for the job. This is just one experiment. But it has given researchers a lot to go on for further testing and also observation of crows in the wild. For instance, how long does this memory last? Can a completely different reward experiment be done, and would the crows remember how this one worked when presented with it later? But right now, it looks like one more unique human trait is falling by the wayside. <a href= "https://www.nature.com/articles/s41598-018-27405-1">Nature</a>, <a href="https://www.bbc.com/news/science-environment-44654098">BBC Science and Environment</a>, <a href= "https://www.nytimes.com/2018/06/28/science/crows-toolmaking.html">New York Times</a>, <a href= "https://www.sciencealert.com/crows-can-remember-tool-shapes-recreate-them-cumulative-cultural-evolution"> ScienceAlert</a> <h3>Scientists are counting seal pups in the Thames Estuary</h3> Maybe a glimmer of good environmental news, for a change! First we go back in time 60 years, when London’s Thames estuary was declared ‘biologically dead’. The river was dirty and almost devoid of wildlife. Since then, things have turned around to some extent - and today we have 3500 seals in the Thames. There are two species, harbour and grey seals. Some of them are about to give birth, so scientists are doing a count to work out how they’re doing. Thea Cox, conservation biologist at the Zoological Society of London, says that "Knowing how many there are is a really good indicator of the health of the estuary, what habitat is available to them, what food source is available to them." This good news story has a sting in the tail - although the river is generally less polluted, we naturally do have to worry about plastic pollution, in particular microplastics, both for our own health as well as that of the seals. <a href= "https://www.bbc.com/news/science-environment-44647967">BBC Science and Environment</a>, <a href= "https://inews.co.uk/news/environment/seals-river-thames/">iNews - Environment</a> <h3>Marshmallow test re-visited</h3> Do you know what the marshmallow test is? It’s a test that was first conducted by Stanford psychologist Walter Mischel to see if there is any correlation between early childhood self-control and later childhood success. Here’s how it worked. The experimenter placed a marshmallow on a table in front of a preschool aged kid. Then the grownup promised to give the kid two marshmallows if they could resist stuffing the first one in their cute little face for 15 minutes. They did these tests in the 1960’s on 90 children in a local Stanford preschool. Decades later they came back to their test subjects to measure their success over the years. And yes, there seemed to be a greater degree of success in kids who resisted marshmallow temptation, including higher test scores and a lower body mass index. The results of this research were published in 1990 and has been a measure of children’s willpower since that time. But a new paper published in the journal Psychological Science suggests that this test, the marshmallow test, may just be a lot of fluff. The new study was led by Dr. Tyler Watts of New York University, and Dr. Greg Duncan and Haonan Quan, both of the University of California-Irvine. And these researchers made a few changes to the test. They increased the sample size from 90 to 900, and they also included a much greater diversity of kids. And these background factors were given consideration when they analyzed the results. And according to Dr. Watts the results showed that once the kid’s backgrounds were factored in, any differences in delaying gratification didn’t result in any statistically meaningful increases in success at a later age. The results suggest that a child’s ability to resist a marshmallow is more influenced by their socio-economic backgrounds. Think about it. If you’re growing up not sure about anything in your life, including when your next meal is happening...then you better grab any food while you can. Also, such a background is more likely to sow distrust in adults promising to give them something...like that second marshmallow. And their future success in school and in life is probably far more influenced by the economic disadvantages of their childhood than by any ability to resist a marshmallow, or other food reward. <a href= "https://www.sciencenews.org/article/kids-waiting-longer-classic-marshmallow-self-control-test"> Science News</a>, <a href= "http://www.sciencemag.org/news/2018/06/why-marshmallow-test-may-be-nothing-fluff"> Science</a>, <a href= "https://www.smithsonianmag.com/smart-news/new-research-marshmallow-test-suggests-delayed-gratification-doesnt-equal-success-180969234/"> Smithsonian</a> <h3>Poliovirus could treat brain cancer</h3> Glioblastoma is a devastating form of brain cancer - it’s the most common type of malignant brain tumour and patients typically do not live for long after diagnosis - best-case scenario is around 20 months. A study published last month by a team at Duke University indicated that a modified form of poliovirus may have some benefits in prolonging life expectancy. But how would POLIO help with brain cancer? The polio treatment is one of several “oncolytic viruses” being investigated as anti-cancer agents. So researchers have long viewed such viruses as potential tools for directly killing cancer - and the virus kills tumour cells and they now suspect that the viruses might be more effective at marshaling the body's immune system against malignancies, according to the National Cancer Institute. As I said, the virus has been modified, so it will not cause polio (this being a horrible disease, causing paralysis and possibly death). It’s modified as follows - the part of the virus that targets and kills nerve cells during a polio infection was swapped with a piece of the common cold virus. Of 61 people with recurring glioblastoma who were treated with the modified virus, 21 percent were alive after three years. In a “historical” comparison group of 104 patients, who would have been eligible for the treatment but died before it was available, 4 percent lived as long. The paper is in New England Journal of Medicine. It is an early phase trial and will naturally face much scrutiny in months and years to come. <a href= "https://www.sciencenews.org/article/poliovirus-treatment-helped-patients-deadly-brain-tumors-live-longer"> Science News</a>, <a href= "https://www.washingtonpost.com/news/to-your-health/wp/2018/06/26/polio-virus-treatment-increased-survival-in-patients-with-deadly-brain-tumors-study-shows/?noredirect=on&utm_term=.7d018a2ff158"> Washington Post</a>, <a href= "https://www.livescience.com/62938-poliovirus-could-treat-brain-cancer.html"> LiveScience</a> <hr /> <h2>The Climate Lounge</h2> Today in the Lounge, I wanted to step back from climate change per-se and talk about an interesting climate feature. DUST! Specifically, Saharan dust that gets transported thousands and thousands of miles across the tropical Atlantic Ocean, causing all sorts of issues. Every year hundreds of millions of tons of dust gets picked over West Africa and blow west by the trade winds over the Atlantic Ocean. Most of the dust is born at the Bodele depression in north central Chad at the southern end of the Saharan desert. It is actually a dry lake bed that is the lowest point in chad. Winds get funneled through nearby mountains, accelerate through and pick up dry diatoms (microorganisms) left over from a time when the lake was an actual lake and transport them west with the prevailing winds. Now this dust causes some unbelievable sunsets across the Caribbean but provides a gross hazy view during the day. The view is like when you mistakenly touch the lenses part of your glasses and then put the glasses back on. The dust is your wayward fingers. But you might be thinking, I’ll deal with a hazy day for a good sunset. Well, the dust can also combine with the normal every day human-caused pollution emitted near cities to create extremely hazardous air quality days. In Dallas Texas, 7000 miles away from Africa, the dust combined with human pollution to cause levels of pm2.5 (particles that smaller than 2.5 microns or 0.0001 inches) which were highly elevated. Why care? Outdoor air pollution, dominated by PM2.5, is responsible for around 4.5 million deaths a year (<a href= "http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)32345-0/fulltext">Landrigan et al. 2017</a>), half of which are in China and India. These particles are such a danger because of just how small they are. At less than 2.5 micrometers, the particles are able to penetrate deep into lungs and even your bloodstream. Extreme exposure to a large amount of PM2.5 can lead to nonfatal heart attacks, irregular heartbeats, reduced lung function, aggravated asthma, and increased respiratory symptoms. In the most vulnerable—those with pre-existing heart or lung disease—exposure to PM2.5 can even lead to death. But there are some positives, Saharan dust, specifically those diatoms, helps to fertilize the Amazon rainforest with nutrients and helps build beaches across the Caribbean. This dust also lives in what is known as the Saharan Air Layer as it moves across the Atlantic, a layer of air that is hot and dry. This hot and dry air mass also helps to kill off any potential tropical cyclone from developing usually leading to a reduced number of storms. Which is good!. And It’s part of the natural climate ecosystem with dust storms happening at the bodele depression about 100 days a year. But it still can cause issues, especially when combined with those non-natural parts of the climate ecosystem. So the next time you watch a video that brings a tear to your eye and you want an excuse, don’t just say you have dust in your eyes, say you have diatoms from the bodele depression in your eyes. You’ll be super cool I promise. <a href= "https://www.wunderground.com/news/2018-07-01-saharan-dust-texas-houston-saturday"> Wunderground</a> <hr /> <h2>Interview with Chris Ryu</h2> <hr /> <h2>Pub Quiz</h2> <hr /> <h2>In Closing</h2> Thank you Chris Ryu for sharing with our audience all the great things you’re doing at the Dorset Science and Technology Centre, and the Atom Club.

074: The Life and Legacy of Koko the Gorilla
<h2>On This Week’s Show</h2> <ul> <li>A**hole of the Month</li> <li>A Farewell to Koko</li> <li>Where’s all the Matter?</li> <li>Three places struggling to control HIV and AIDS</li> </ul> <hr /> <h2>Science News with Sophie McManus and JD Goodwin</h2> <h3>A Farewell to Koko</h3> <h4>Sophie McManus</h4> Koko, the famous ‘talking gorilla’, has died in California aged 46. Koko was born in 1971 in San Francisco zoo and when she became ill she needed hand-rearing. The student for the job was Penny Patterson, who also taught her some American sign language. In a couple of years Koko learned 80 signs, before she was moved to Stanford University. It is claimed she could understand 2000 English words and knew 1000 different signs. Apart from that, Penny Patterson described evidence for a sense of humour and a charming and creative sense of word play - she referred to a zebra as a ‘white tiger,’ a Pinocchio doll as an ‘elephant baby,’ and a mask as an ‘eye hat’. Koko famously loved cats - her favourite kitten was called All Ball, and the way she handled her kittens is obviously full of care. She tickled Robin Williams back in 2001 and it was claimed she ‘grieved’ when told of his death. Koko’s life and treatment attracted scepticism and criticism as well as plaudits. The former arose from overinterpretation of the results she gave scientists - after all, she was taught to sign, mainly to respond to humans, it was not a spontaneous desire to communicate or chit-chat as human infants have. There is also the danger of projecting human emotions onto animals. For example, my family has dogs, and although we think they show emotions like jealousy (like when one tries to steal the other’s food), this may partly be our projections. (Secretly still convinced the young one gets jealous). The fact Koko trembled her lip when told Robin Williams was dead may not be crystal clear signs of grief. An example of projection and over-inference in animal studies is that of the horse Clever Hans. The criticism was also born of her environment and diet - although she was given many toys (and pets), obviously her home was entirely unnatural for a gorilla, her diet was humanised, she was given many different supplements by a ‘naturopath’, and she didn’t have the chance to socialise with other gorillas. Slate published a fantastic article summarising the many criticisms of ape sign studies. Her species, the western lowland gorilla, is considered critically endangered today. Today, studies into ape communication such as the study of Koko’s life are less likely to receive ethical approval. Quote from Barbara King, an anthropologist - it's not very respectful of the world's biodiversity to insist upon making apes into furry versions of ourselves. Koko taught us so much about the great ape mind, even while she paid a cost, in her own daily life, for our scientific curiosity. So generally then, Koko was a star, but we shouldn’t be looking to replace her. <a href= "https://www.newyorker.com/culture/postscript/remembering-koko-a-gorilla-we-loved"> The New Yorker</a>, <a href= "https://www.npr.org/2018/06/21/622160278/koko-the-gorilla-dies-redrew-the-lines-of-animal-human-communication"> NPR</a>, <a href= "https://www.bbc.com/news/world-us-canada-44559261">BBC News</a>, <a href= "https://www.sciencenews.org/article/koko-gorilla-gone-she-left-legacy"> Science News</a>, <a href= "https://news.nationalgeographic.com/2018/06/gorillas-koko-sign-language-culture-animals/"> National Geographic</a> <a href= "http://www.slate.com/articles/health_and_science/science/2014/08/koko_kanzi_and_ape_language_research_criticism_of_working_conditions_and.html?via=gdpr-consent"> Great article in Slate</a> <h3>Have scientists finally found the universe's missing matter?</h3> <h4>JD Goodwin</h4> Most of us have heard that everyday matter, the stuff that we can observe like atoms and molecules, make up only a small percentage of the universe. Dark energy comprises about 70%, and dark matter is about 25%. Although we don’t know exactly what they are we can calculate their mass by their effects on what we can observe. But there’s that roughly 5% of everything that is ordinary matter, more accurately known as baryons. We know this from observations of the Cosmic Microwave Background Radiation. So we’re on pretty solid ground there. After years of observing galaxies, and using every tool in the cosmologists’ toolkit we’ve only been able to observe half of the predicted baryonic matter, the ordinary matter, that the universe should have. Last week a paper was published in Nature that just may very well account for the missing baryonic matter in our universe. The paper’s lead author, Fabrizio Nicastro said: “The missing baryons represent one of the biggest mysteries in modern astrophysics.” But progess has been made over the years. Astrophysicists have calculated the mass of all the stars in the universe. They then added in the interstellar gas inside of galaxies and this up to about 10%. I’m not talking 10% of the mass of the universe, just 10% of the expected mass of baryons, which as you now know, comprises only about 5% of the universe’s total mass. Still with me here? Okay, we’re up to 10% of baryonic matter. Now add in the gas that surrounds galaxies like gigantic haloes. Then toss in the even hotter gas that fills galaxy clusters. That now brings us up to almost 20%. Better, but not particularly satisfying. Through some different observational techniques astronomers then turned their attention to the super colossal gas filaments that run between galaxy clusters. And that brought up to 60% of the predicted baryonic matter. Now we’re getting somewhere. And here’s where the this new paper by Nicastro and his team comes into play. They didn’t just start looking last week, by the way. They’ve been at this for almost 20 years. The team used the XMM-Newton X-ray observatory to observe a quasar. A quasar is a galaxy with a supermassive black hole at its core that emits intense radiation in the form of x-rays all the way to visible light. According to Nicastro, “After combing through the data, we succeeded at finding the signature of oxygen in the hot intergalactic gas between us and the distant quasar, at two different locations along the line of sight. This is happening because there are huge reservoirs of material – including oxygen – lying there, and just in the amount we were expecting, so we finally can close the gap in the baryon budget of the Universe.” This was one paper, although it took them 20 years to get to this point. Still, they have plans to look at more quasars with the XMM-Newton and NASA’s Chandra space observatories. Also, better space observatories are scheduled to be launched in the late 2020’s that will provide even more data. But right now it seems we have found all the ordinary matter in the universe. <a href= "https://www.esa.int/Our_Activities/Space_Science/XMM-Newton_finds_missing_intergalactic_material"> European Space Agency</a>, <a href= "https://www.scitecheuropa.eu/xmm-newton-space-observatory-material/87495/"> SciTech Europa</a>, <a href= "https://www.outerplaces.com/science/item/18634-found-universe-matter-baryon"> Outer Places</a>, <hr /> <h3>These three places show the AIDS epidemic is far from over</h3> <h4>Sophie McManus</h4> Florida, Russia and Nigeria. Different corners of the world, united by the fact they are all struggling to up the ante against HIV and AIDS infection. These are the metrics we can use to gauge progress made in the fight against HIV, as explained in an excellent article published in Science. How many people are living with the virus? What is the rate of new infection? What percentage of infected people are receiving antiretroviral drugs, which both stave off disease and prevent transmission? How many infected people have progressed to AIDS and how many have died from it? And how many children are infected by their mothers? Nigeria, Russia and the American state of Florida stand out from their neighbours because they are ‘first’ for at least one of the metrics I just mentioned. They all face differing challenges. For example, Nigeria has a high rate of mother-to-child HIV transmission, Russia has a high death rate. Florida has a high new infection rate, partly because many people there with HIV are unaware of their status, as testing isn’t as widespread as it could be. If you are a data nerd, you should look up the article called ‘Ending AIDS? These three places show the epidemic is far from over’ published on the 14th June on the Science website. There are some great interactive charts and graphics that elegantly sum up the data. <a href= "http://www.sciencemag.org/news/2018/06/ending-aids-these-three-places-show-epidemic-far-over?rss=1"> Science</a> <hr /> <h2>A**hole of the Month</h2> <h3>Elliot Sudal, publicity seeker and shark abuser</h3> Have you seen the headlines? "World's Sexiest Shark Wrangler? Jaws Are Dropping Over this Ab-Tastic Ocean Expert's Instagram". That was from People Magazine in May. From the Daily Mail also in May, "Picture of shark wrangler holding a 12-foot hammerhead goes viral – but it's not for the reason you're thinking". I’ll tell you the reason. Yes, it’s his rippling abs! I’m talking about Elliot Sudal, the latest internet sensation who hooks and captures these menacing monsters from the deep and wrestles them ashore, all the while looking ABSolutely fabulous doing it. But this is 2018, and the good guys don’t slaughter sharks any more. After wrestling the fearsome beasts on to the beach Mr. Sudal does what any modern day muscle-man would do. He poses alongside, and sometimes sits on these vanquished creatures. He even invites other people to do the same, especially if they look really awesome in a bikini. Being the good guy, Mr. Sudal applies a tag to the shark before dragging it back into the water, after the photo op of course, and lets it go back into the deep. What a great guy! According to the Daily Mail, “He works for the National Oceanic and Atmospheric Administration,” and that “Sudal's job takes him to exotic locations like the Bahamas and Nantucket catching anything from bull sharks to sting rays.” Let’s hear what his employer, the National Ocean and Atmospheric Administration has to say about their star employee and shark hunter Elliot Sudal: <blockquote> “Mr. Sudal is not and has never been an employee of NOAA Fisheries nor is he formally affiliated with any of the agency’s programs. The agency remains concerned with Mr. Sudal’s shark and sawfish handling practices. Physical handling should be minimized, all species should be kept in the water while tagging and then released quickly. During tagging, sharks should not be dragged onto dry sand...for any reason. Mr. Sudal’s tagging of an endangered smalltooth sawfish caught in Florida in April 2017 was investigated by NOAA and resulted in a compliance assistance letter from NOAA’s Office of General Counsel informing him of the Endangered Species Act issues and the safe handling protocol for sawfish.” </blockquote> This public notification by NOAA is highly unusual, and reflects the seriousness of the situation. Mr. Sudal has been presented in the media as an employee of NOAA. That is false. Mr. Sudal has been claiming to be a conservationist. Mr. Sudal has violated nearly every guideline of NOAA’s shark tagging guidelines. But hey, those pictures and the viral videos are awesome, huh? So awesome that they’ve landed Elliot Sudal on the beach as the Blue Streak Science A**hole of the Month. <a href= "https://www.theatlantic.com/national/archive/2013/07/letting-sharks-off-the-hook/278117/"> The Atlantic</a>, <a href= "https://www.adventuresportsnetwork.com/sport/fishing/miss-maine-usa-contestant-a-prolific-shark-tagger-but-is-this-conservation/"> Adventure Sports Network</a>, <a href= "https://abcnews.go.com/US/man-photographed-wrestling-shark-ashore/story?id=19682461"> ABC News</a>, <a href= "http://www.dailymail.co.uk/news/article-5716467/Florida-shark-wrangler-brings-huge-hammer-head-goes-viral-muscles.html"> Daily Mail</a>, <a href= "https://www.nefsc.noaa.gov/nefsc/Narragansett/sharks/pdfs/cstpbooklet.pdf"> NOAA shark tagging guidelines</a>, <a href= "https://www.fisheries.noaa.gov/feature-story/noaa-fisheries-statement-recent-inaccurate-media-coverage-shark-tagging-elliot-sudal"> NOAA press release</a> <hr /> <h2>Where Have We Been?</h2> JD: I visited Point Blue Conservation Science. Point Blue is a private conservation science organization that is, honestly, far bigger and more wide-ranging that I’d thought. They used to be known as the Point Reyes Bird Observatory, but they took on the moniker of Point Blue Conservation Science because their scope is much wider than just birds. They are certainly California-centric with research going on all over the Bay Area, offshore including the Farallone Islands, and as far away as Alaska all the way down to Antarctica! I met several of their key staff members who seemed quite keen to share their research, and hopefully we’ll be sharing that with you, our audience. <h2>Where Are We Going?</h2> JD: I have nothing planned, except to practice some video techniques with my new gimbals. <hr /> <h2>In Closing</h2> And that concludes this episode of the Blue Streak Science Podcast.

However, I'm rather baffled at how some of these people acquire these high state positions." <hr /> <h2>Science News with Dr. Amrita Sule and Chris MacAlister</h2> <h3>Antarctic Melt Rate Has Tripled in the Last 25 Years</h3> Antarctica is a continent roughly the size of United States and Mexico combined. It is covered with ice sheets. If all of this ice were to melt it would increase the water levels by 60 meters. Although this is not going to happen overnight and these ice sheets have more or less remained in place for past 10,000 years. <img class="size-medium wp-image-1025" src= "https://bluestreakscience.com/wp-content/uploads/2018/06/73_800x500-300x188.png" alt="" width="300" height="188" /> Antarctic Petrel But Antarctica is indeed melting!! Reports published recently revealed that Antarctica has lost around 3 trillion tons of ice in just the past 25 years, and this ice loss has accelerated rapidly over the last five years. This is pushing up the global sea levels by 0.6 mm annually – which might seem pretty small but it’s not if you look at cumulative increase. For this new study, satellite measurements have been used to track changes in ice sheets since the early 1990s. These satellites scanned Antarctic ice sheets with altimeters to gain information about its volume. Another type of satellite measurement tracked the speed at which it moves towards the ocean. Some satellites are equipped to weigh the ice sheet by sensing gravitational pull of earth. These measurements are helpful in telling you what is its sea level contribution. There has been some uncertainty associated with regional differences in Antarctica. This study helps clear that up. For example, West Antarctica and Antarctic peninsula, have been known for some time to lose ice but not east Antarctica, which has been stable for most time. Therefore East Antarctic has always caught the attention of people who deny the science of Global Warming. But recent studies show higher melt rates in certain regions east Antarctica as well. So there you go! The majority of losses do come from melting of West Antarctic ice sheets due to warm ocean water melting some glaciers from the bottom up. In 25 years, this has caused about 8 millimeters of sea level rise and about 40% of this rise has happened in past five years. This definitely increases our concern about what the future may hold. <a href= "https://www.bbc.com/news/science-environment-44470208">BBC Science and Environment</a>, <a href= "https://www.livescience.com/62811-antarctica-3-trillion-tons-ice-lost.html"> Live Science</a>, <a href= "https://www.scientificamerican.com/article/antarctic-melt-rate-has-tripled-in-the-last-25-years/"> Scientific American</a>, <a href= "https://www.nytimes.com/2018/06/13/climate/antarctica-ice-melting-faster.html"> New York Times</a>, <h3>Mars Rover Opportunity Hunkers Down for the Big Dust Storm</h3> Did you guys ever see the Martian, with Matt Damon? Despite the lead character being a botanist and the wealth of good science that is in the film; the main event that triggers the plot of the film, the big Martian storm is not so scientifically accurate. Mars has a much thinner atmosphere than Earth so Martian storms don’t reach anything like the severity of our storms. That said, this story is about the Mars rover, Opportunity being put at risk by a Martian storm. And not just any Martian storm but the biggest one ever recorded! The threat to Opportunity isn’t from the physical impact of the storm itself, but from the Martian dust that is getting blow around in it. Opportunity is solar powered and a big storm like this will seriously reduce the amount of sunlight that makes it down to planet’s surface. Now, this storm was predicted so Opportunity has been put into maximum power saving mode and now all that the guys at NASA can do now is hope that the batteries can outlast the storm. This isn’t the first time the Opportunity has had to endure a storm like this but there are two crucial differences on this occasion. First, as I said earlier, this is the biggest storm seen to date on Mars, and second; Opportunity is no spring chicken anymore. It is staggering to think about what Opportunity has achieved in its time on Mars. The rover’s mission was initially given a duration of 90 days; this mission is now at well over 5000 days and counting! No other rover has ever covered more distance off world. Opportunity completed a Martian marathon 3 year ago and then kept going! Opportunity will remain in hibernation for a few weeks so we won’t know anything until the time comes to rouse it from its slumber. But even if this does spell the end for the opportunity mission, that little rover owes nothing to anyone. It has vastly outperformed anything that anyone ever expected of it and it will have deserved a very well earned rest. <a href= "https://www.livescience.com/62817-will-mars-rover-survive-dust-storm.html"> Live Science</a>, <a href= "https://www.livescience.com/62810-mars-dust-storm-opportunity-falls-silent.html"> Live Science</a>, <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-opportunity-mars-dust-storm-20180613-story.html"> LA Times</a>, <a href= "https://www.space.com/40888-mars-dust-storm-2018-and-opportunity-rover-images.html"> Space.com</a>, <a href= "https://news.nationalgeographic.com/2018/06/mars-rover-opportunity-dust-storm-nasa-space-science/"> National Geographic</a> <h3>Humans Forcing Animals To Become Nocturnal</h3> Coming back to earth, let’s see what are WE up to and by WE... I mean human beings. Looks like we have now managed to annoy some animals to an extent that they rather sleep through the day and stay up at night just to avoid us. Count me in too. We “humans” have now impacted about 75% of earth’s land surface and therefore animals have opted to adapt to a different lifestyle especially when they are in proximity of cities or areas buzzing with human activity. Many animals fear humans and we do come across as noisy and dangerous to them. So they often try to avoid us. But it is becoming more and more difficult for them to migrate to a human free space. Why? Because WE are everywhere. A study published in Science this week pointed out that mammals across the globe not just limited to coyotes, elephants and tigers have altered their sleep schedules and are becoming increasingly nocturnal to avoid increased human presence. This kind if behavioral activity has been tracked over last couple of decades by satellites, GPS telemetry or camera traps. This study is a result of meta-analysis of 76 papers about 62 different species spanning six continents. They looked at a share of nocturnal activity that was conducted by animals living in regions with low and high levels of human impact or disturbance. Regions with higher human activity correlated with increased nocturnal activity. And theses observations or trends were consistent across continents, habitats, types of animals and even types of human activity. The author of this study makes a point that, this kind of behavioural shift could have large impacts on ecosystem thus reshaping species interaction. Competitions between predator species could threaten their survival. Also, the animals that are not opting for nocturnal lifestyle could be endangered due to human presence. It's important to remember that we are not alone on earth, and more effort should be made to conserve human disturbance free zones especially for most vulnerable and sensitive mammal species. <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-mammals-active-at-night-20180614-story.html"> LA Times</a>, <a href= "https://www.nytimes.com/2018/06/15/science/animals-human-nocturnal-study.html"> New York Times</a>, <a href= "https://www.nature.com/articles/d41586-018-05430-4">Nature</a>, <h3>Stephen Hawking buried in Westminster Abbey, between Darwin and Newton</h3> In the preparation for this show, JD shared his recollection of a biography on Charles Darwin. It contained a chapter about his burial in Westminster Abbey and was entitled “The Agnostic in the Abbey”; well, it would appear that Darwin has now been trumped as the atheist, Stephen Hawking was also interred there last week. The best way to explain what a privilege it is for Hawking to be buried here is to consider who else has also been bestowed the honour. He rests alongside 18 past monarchs, Geoffrey Chaucer, Oliver Cromwell, Charles Dickens, Thomas Hardy, Rudyard Kipling and Laurence Olivier there are 5 other people from a scientific background; Margaret Cavendish, Isaac Newton, Charles Darwin, Ernest Rutherford, J. J. Thomson and now Stephen Hawking. Now there may be critics who say that Hawking doesn’t deserve to be laid to rest with the likes of Newton and Darwin. The established works of those two men still form significant pillars within our body of current scientific understanding whereas Hawking’s work is still to have its accuracy verified and he hasn’t even won a nobel prize. Well guess what, neither did Newton or Darwin! By the time that Darwin died, On the Origin of Species had only been published for 20 years; not nearly enough time to test the theories that he presented. This puts Hawking’s ideas very much at the same level. But we can’t just look at the science here. The true power of Stephen Hawking was as a communicator. It’s seems so poetic that a man who spent half of his life without a voice has been one of the greatest science communicators of all time. Regardless of his scientific credentials (which are pretty phenomenal) the people honoured in Westminster Abbey are people who have created a lasting legacy in the UK and I can’t think of anyone who I have met who has not been inspired by the life of Stephen Hawking. But I think that we can only end a piece like this by sharing a few pieces of classic Hawking dialogue, like: “I have noticed that even people who claim everything is predetermined and that we can do nothing to change it, look before they cross the road”, and “Next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection, neither you nor I would exist.” And finally, “However bad life may seem, there is always something you can do, and succeed at. While there's life, there is hope”. And even though Stephen Hawking’s life may now be over, the hope that he has brought to so many people lives on. <a href= "https://www.livescience.com/62836-hawking-buried-between-newton-darwin.html"> Live Science</a>, <a href= "https://www.theguardian.com/science/2018/jun/15/stephen-hawking-ashes-interred-westminster-abbey"> The Guardian</a>, <a href= "https://www.westminster-abbey.org/abbey-news/ashes-of-stephen-hawking-buried-in-the-abbey/"> Westminster Abbey</a> <hr /> <h2>Patreon</h2> The Blue Streak Science Podcast is a listener-supported podcast.

I trundled over to the Fish Docks on the beautiful Drake’s Bay. Met up with some other birders and searched for the Lawrence’s Goldfinches. No dice. I did get great views of many other birds such a lesser goldfinches, a soaring peregrine falcon. The highlight was a large male California sea lion emerging at the surface with a fat chinook salmon in its mouth. It then shook the salmon, tearing it apart, with salmon roe flying everywhere. It was immediately joined by a host of western gulls to help clean up the mess. <h2>Where Are We Going?</h2> JD: Nothing on the agenda, but more birding. I may go back to Point Reyes on Wednesday to give the Lawrence’s Goldfinches another shot. I hope to be up to speed by then on the new gimbals I have for taking smooth video with my iPhone. I may even do some audio recording as well. Chris: Camping in the Lake District. <hr /> <h2>In the Blogosphere</h2> Chris: I’ve been doing some homework following last week’s show. Sunlight takes 5.3 hours to reach Pluto. JD, you are correct; it takes 8 minutes for light to get to Earth and my figure of 8 minutes is actually the time that it takes light to reach Mercury. I’ve also been investigating Space Suit malfunctions. It appears that the worst spacesuit malfunction occurred in 2014 and it was not necessarily what you may have expected as the danger to astronaut Luca Parmitano was of drowning! Now the use of this word isn’t some technical definition of suffocation; it actually means drowning in water, in space! A blocked filter in the space suit caused a leak and his helmet started filling with water from the suit’s cooling system during a spacewalk. This eyes, ears, nose and parts of his mouth all filled up with water. He could barely see and had to feel his way back to the air lock. Why does the suit hold so much water and why a cooling system is needed when it is -270 Celsius outside, but this is because spacesuits need a lot of insulation to protect astronauts so it can get pretty toasty in there so they even have clothing that draws sweat away from the body and then cools it. Even though NASA have never seem to figure out what caused the failure, they have taken protective action by installing snorkels into helmets now! This week I am writing about a subject very close to me, sunburn. Not just why it happens but also why its red, when nothing else ever goes red when it gets burnt. <hr /> <h2>In Closing</h2> Thanks to our intrepid hosts, Amrita Sule and Chris MacAlister!

072: Organic molecules on Mars, slowing hurricanes, dogs and influenza
<h2>On This Week’s Show</h2> <ul> <li>New Horizons wakes up to explore the Kuiper Belt</li> <li>Hurricanes are slowing down</li> <li>Dogs and the flu virus</li> <li>The Climate Lounge</li> <li>The Pub Quiz</li> </ul> <hr /> <h2>Science News with Nevena Hristozova and Chris MacAlister</h2> <h3>Organic molecules found on Mars</h3> Mars stinks. Or at least it ought to, based on the fact that in has methane in its atmosphere. Truth is though, that the concentration of methane in the martian air is almost 2000 times lower than the one on earth. But why methane is of interest to scientists is because, on earth at least, it’s existence is related to the activity of living forms. Now, methane comes again in the spotlight of researchers, because they’ve finally had a breakthrough - they’ve finally detected a pattern in the concentration variations of the gas in the martian atmosphere. Curiosity observed changes in the methane content when travelling cross the planet from north to south. The original hypothesis was that this change is due to chemical conversion of molecules with the help of the strong radiation of the Sun. The counter argument is that while this is possible, its not plausible, or at least not explaining the phenomenon in full. The models predict only about 20% increase in methane if the conversion is due to only sun-catalysed chemical conversions in the summer, while the practically observed increase is with up to 300%. Alternative hypothesis is that there might be methane deposits in the deep ice on Mars, which gets released once the ice and soil get warmed up by the summer sun. It is still very interesting to find out though where did this methane came from in the first place and future ESA missions will look exactly into that - they will be able to drill much deeper in the martian soil and analyze the carbon composition of the methane found there to establish if there’s a chance it was made/left behind by living forms. <a href= "https://www.bbc.com/news/science-environment-44405658">BBC Science and Environment</a>, <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-mars-methane-seasons-20180607-htmlstory.html"> LA Times</a>, <a href= "https://www.sciencenews.org/article/curiosity-finds-mars-methane-changes-seasons"> Science News</a>, <a href= "https://news.nationalgeographic.com/2018/06/mars-organic-compounds-methane-curiosity-space-science/"> National Geographic</a>, <a href= "https://www.nytimes.com/2018/06/07/science/mars-nasa-life.html">New York Times</a> <h3>New Horizons wakes up to explore the Kuiper Belt</h3> Last week I spoke about the discoveries coming from New Horizons’ 3 year old data and before we’ve even finished with all of that data; here comes some more! After the success of the Pluto flyby the mission was extended for further studies in the Kuiper belt, and why not; after the 9 years getting there? Pluto’s home, the Kuiper belt may be less famous than asteroid belt between Mars & Jupiter but it is a damn sight bigger! Despite covering some 3.5 billion kms to get to Pluto, its taking New Horizons a further 3 years and 1.6 billion miles to complete this leg WITHIN the Kuiper belt! The new target is called Ultima Thule (much catchier than its official title 2014 MU69). The name, given in March of this year, means; beyond the borders of the known world. Ultima Thule is exciting for a couple of reasons. It could be both the most distant oldest object ever studied, it is believed to have been orbiting since the very early days of the solar system some 4.6 billion years ago. A 20km wide rock may not seem too exciting. But if Pluto has taught us anything t is that surprises are waiting out there to be discovered. And who doesn’t get excited about exploring a new world? I’m ready to get excited again. As with your own tech, if you’re not going to use it for some time you may switch to standby mode and this is exactly what’s happened to New Horizons. Waking it up means that it’s time for the discovery to start again. I think the mission’s principal investigator Alan Stern summed it perfectly when he simply said “IT’S HAPPENING, IT’S HAPPENING!”] <a href= "https://www.sciencenews.org/blog/science-ticker/new-horizons-wakes-begin-kuiper-belt-exploration"> Science News</a>, <a href= "http://www.spaceflightinsider.com/missions/solar-system/new-horizons-exits-hibernation-to-prepare-for-kbo-flyby/"> Space Flight Insider</a>, <a href= "https://www.space.com/40832-new-horizons-wakes-up-for-historic-kbo-flyby.html"> Space.com</a>, <a href= "https://www.nasaspaceflight.com/2018/06/new-horizons-leave-hibernation-january-mu69-flyby/"> NASA Space Flight</a> <h3>Hurricanes are slowing down</h3> I’m getting into deep waters here - this is entirely Tom’s turf but my name’s not Nevena if I don’t do my best so here goes nothing! Yes - a paper published recently in the journal Nature shows that hurricanes are moving slower and that seems to be a very very bad thing. Here’s why - having both typhoons and hurricanes move slower means that they drag along for longer in a specific area and respectively cause more damage. The warmer air and water also pump more water into the storm so they tend to be much more prominent and drop much more rain for prolonged periods one one place causing more frequently and worse floods. Another research paper published by the NSF analysed 22 storms and modeled how would they develop if they were to happen in the climate conditions of the late 21 century. And it was not pretty! The predictions showed that the rising global temperatures will only cause cyclones to slow down further, making them even more deadly and devastating for the areas affected by them, calculating as much as 25% more rainfall for all the biggest storms analysed in this study. Now you might think - ok rain would be worse but since it’s travelling slower at least the damage from the winds will be significantly smaller, but you’d be very wrong - the winds in the storms apparently remain with comparable speed to the ones today. And according to some estimations, this slowing down of storms transitions is very significant, some calculating as much as a third loss of speed for just over half a decade. These two publications both point to the same outcome using two very different methods - one is analysing historical data, and the other one is making predictions based on computer modeling. The fact that both have similar disturbing conclusions is a hint at the much more versatile unexpected negative effects of global warming we are yet to discover in full. <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-slower-hurricanes-cyclones-20180606-story.html"> LA Times</a>, <a href= "https://news.nationalgeographic.com/2018/06/hurricanes-cyclones-move-slower-drop-more-rain-climate-change-science/"> National Geographic</a>, <a href= "https://www.nature.com/articles/d41586-018-05324-5">Nature</a>, <a href= "https://www.nytimes.com/2018/06/06/climate/slow-hurricanes.html">New York Times</a> <h3>Dogs and the flu virus</h3> You’ve got your bird flu, your swine flu, now get ready for dog flu! Bird flu made the case that flu is not just what you called in sick with when you have a bad cold but could actually be a serious, life threatening disease. I could talk all day about the complexities and risks of the flu virus but I won’t. Instead we’ll focus on the headline points. Is your dog in danger? No. This story is about discovering that dogs already have many different types of flu virus in them, including some novel ones; not that dogs are dying. Are you in danger? No. So why are we even talking about this? The reason why people get a flu shot every year is because the flu virus is eternally changing. Antibiotic resistance is not a patch on the flu virus. Flu is a pandemic on a never-ending migration and as flu season sweep around the globe it keeps on changing. It mutates, swaps genes with its hosts and it swaps genes with other varieties of flu. All of this genetic bodging means that the flu that hits you one season can be significantly different from the one that hit you last season, dodging your immune system. So your flu vaccine is guesswork, predictions of what strains will be doing the rounds in the coming season. The reason this dog story is big news is that all these flu strains together makes for a breeding ground for new strains as they all go about swapping genetic material; increasing the chance of something dangerous like bird flu emerging. Bird flu never transferred directly between humans and was rare as you had to live closely alongside infected birds to get it. But dogs live very close with us, not only raising the potential for infection, but also giving the virus more chance of adapting to infect humans. This has led to claims that we should start vaccinating our dogs for flu, not to protect them but to reduce the number of strains that they are carrying and minimise all this mixing. JD: This winter we had our dog, Amy, vaccinated against canine flu. It seems there was some of it going around here on the west coast of North America, and it is quite serious if your dog is unlucky enough to contract it. Also, our veterinarian told us that the series of two injections should protect her for life. <a href= "https://www.sciencenews.org/article/dogs-carry-surprising-variety-flu-viruses"> Science News</a>, <a href= "https://www.livescience.com/62770-dog-flu-pandemic.html">Live Science</a>, <a href= "https://news.nationalgeographic.com/2018/06/dog-flu-pandemic-explained-health-science/"> National Geographic</a> Thanks to Nevena Hristozova, the mastermind behind the incubatorium blog.

And Chris MacAlister who is the creator of <a href= "http://www.matildaslab.wordpress.com">Matildas Lab</a>, whose most recent post is about strapping fake tails to chickens. <hr /> <h2>The Climate Lounge</h2> Did you know that according to a new paper in Nature, hurricanes are slowing down because of climate change? You do? Because Nevena already covered it really well? How about that science huh? Let me look at my watch...Ok that was only 20 seconds. Give me a word! Which connects me to... CARBON DIOXIDE. Let’s talk CO2! Because we did it guys! Woo! We are number 1! Humans Humans Humans! This April and May, the amount of Carbon Dioxide in the atmosphere measured at Mauna Loa in Hawaii reached 410 parts per million. The highest monthly averages ever recorded. May’s average was 411.25 ppm, which is like super high. How high is that? Well it’s likely the highest since the Pliocene around 3 million years ago. What’s the Pliocene? It’s an era of time. What’s time?Dudeeee that’s deep. Anyway, the pliocene was known to have sea levels 16 to 131 feet higher (5 to 40m), the poles were 10 C or 18F higher with global temps more like 3-4C warmer (5-7F). And giant ground sloths and mastodons roamed the planet, not 7.6 billion humans. Suffice to say, yikes. Now this is where I usually get into some super sciency details but I’d like to end with a story instead, if you guys don’t mind. Around 3.5 years ago I was lucky enough to get invited to give a talk at a climate resilience conference in Hawaii focusing on the Pacific Islands. And like any normal person, I extended this trip to do some sightseeing with my then pregnant wife (we had just found out a month earlier that we were expecting our first child). Our travels took us the big island, the youngest of the islands and the one that’s currently erupting. Now when you are there, the suggestions on things to do usually boil down to 1) see the volcano and 2) Get to the top of Mauna Kea to see the stars and telescopes that peer out into space. We did #1 but thought, Psshhhht space. We instead did the much less traveled adventure and drove up Mauna Loa. Because we wanted to see where the famous Keeling Curve observations (the co2 measurements that i mentioned earlier) were taken. So beforehand, I emailed the NOAA scientists up there and said “Hey, can we come visit?” They said Sure! And gave us the code to the front gate. So on a sunny typically beautiful hawaiian day, my pregnant wife and I drove a rented 4wheel drive jeep up switchback roads to the Mauna Loa observatory. We walked around the machines by ourselves for a little bit before running into one of the scientists. He showed us around making sure to stop at the old famous machines,then pointing out where the steady stream of data was coming in and finally making us sign their guestbook (which contained all sorts of more famous names). But then he surprised us and took us out onto the roof, he grabbed an air sample bottle that they obviously kept for situations like this, when random visitors show up and he let us take air samples on Mauna Loa ourselves and seal the jars. We then went back down and wrote down the current CO2 levels in ppm. 401.23 ppm. A terrifying number back then. It was a time when breaking 400ppm seem unfathomable. And now 411.25ppm, rising and my son is now 2.5 years old I often get asked how I keep going in such a field like climate science. Communicating it can be so tough. Things can seem so polarized, hopeless. And nowadays, I don’t think we alone own that hopeless mantle. But I always say, you have to remind yourself why you keep doing what you are doing Yes it can be tough, and on some days it can seem impossible to keep going. But on those days, I look to the shelf right above my computer at work, to the photo of my wife and I on our wedding day, to the image of my son showing off the world’s largest grin. And smack dab in between them is that little glass tube, full of that brilliant hawaiian air with ugly amounts of CO2 in it. And as I say these words, at any minute I could get a call telling me my wife is in labor with boy #2. So even though things can seem depressing. Remember, there’s A LOT worth fighting for. Keep those things close and let’s get to damn work. Also, don’t be afraid of bringing tourist dollars to Puerto Rico and definitely don’t forget to keep talking about the island. It’s hurricane season and lots of places still don’t have roofs. <a href= "https://research.noaa.gov/article/ArtMID/587/ArticleID/2362/Another-climate-milestone-falls-at-NOAA%E2%80%99s-Mauna-Loa-observatory"> NOAA</a>, <a href= "https://e360.yale.edu/digest/co2-levels-break-another-record-exceeding-411-parts-per-million"> YaleE360</a> <hr /> <h2>Pub Quiz</h2> <ol> <li>What is the study of biological processes that have or could have evolved outside or away from the planet Earth?</li> <li>What do we call a global event that arises from large-scale interactions between the ocean and the atmosphere between the southeastern tropical Pacific and the Austral-Indonesian regions?</li> <li>What is the branch of biology that deals with the interactions and relationships between organisms and their environment?</li> <li>What do we call a subatomic particle that carries a negative charge in atoms or molecules?</li> <li>Microorganisms belonging to the domains Bacteria and Archaea that can live and thrive in extreme environments are called what?</li> <li>In thermodynamics, a closed system evolves toward a state of maximum what?</li> <li>Published in 1859, Darwin’s “On The Origin of Species”, probably the greatest writing in the history of the biological sciences.

It’s a co-production of BBC’s World Service and Norway’s public radio service, NRK. In 1970, in a remote valley in Norway two girls found the body of a woman, badly burnt and surrounded by some strange objects. Her identity has remained a mystery ever since. Investigative journalist, Marit Higraff, and British BBC radio documentary maker, Neil McCarthy, have spearheaded this most recent investigation, and their goal is to find answers that have evaded police, journalists and crime novelists for the past 47 years. This is a wonderful podcast and I urge you to have a listen. <a href= "https://itunes.apple.com/us/podcast/death-in-ice-valley/id1357695290?mt=2"> Death In Ice Valley</a> <hr /> <h2>Where Have We Been?</h2> Nevena: Last week, here in Brussels, was held the yearly international forum on food and nutrition from the BCFN foundation. It is an event founded to provide an open space for interdisciplinary discussion on issues of nutrition and sustainability. Experts, international opinion-makers and young research fellows met to share evidence, scientific data and best practices, with the goal of creating a model of sustainable food to reach the United Nations 2030 Sustainable Development Goals. The talks and keynotes tried to lay out effective solutions on urgent issues such as the relationship between hunger and obesity, the proper use of natural resources, the reduction of food waste, the promotion of sustainable diets, the environmental impact of agriculture and the effects of climate change. And the best part of this event was that it was free to register so anyone who wanted to attend and was fast enough could go (obv they had a somewhat limited number of seating). But talk about open science that was really it! JD: Last week I spent a morning at Point Reyes National Seashore. This is truly a remarkable piece of land. It’s about 280 square kilometers and its peninsula juts about 15 kilometers out into the Pacific. From the Outer Point you can see the Farallones, an archipelago that’s about 50 km away. On a clear day you can also see the top of the Golden Gate Bridge, also about 50 km distant. There are lots of black-tailed deer, huge tule elk, bobcat, coyotes and mountain lions. I was doing some birding there and saw several peregrine falcons soaring and then swooping around the lighthouse, driving the common murres crazy. I only learned afterward that a pair of Lawrence’s Goldfinches are nesting in the area...quite rare for this location. Chris: This week I have been building. I am building a LIMS (Laboratory Integrated Management System). Our lab records are on old Microsoft Access databases that are slowly grinding to a standstill. A colleague and I visited another lab to look at their off the shelf LIMS and we thought; there’s nothing going on here that we couldn’t build ourselves, in MS Access. So that is what we are doing; building an all-singing-all-dancing bespoke database system from scratch. Whilst this has been going on for more that the last week, last week we did build some parts of the system that we feared would be the most difficult so I’m feel remarkably chuffed with myself at the moment. <h2>Where Are We Going?</h2> Nevena: Another interesting event which I hope to be able to attend is a meeting called Antitrust and competition issues in the life science sector on July 3rd here in the European Parliament, in Brussels. DG COMP organises a panel to provide an overview of recent developments by DG COMP and the National Competition Authorities in the life science industry, including excessive pricing, market definition, pay-for-delay, and mergers. This event follow the launch of DG COMP’s Pharmaceutical Sector Inquiry in 2008, in which inquiry was the interplay between competition law and the life science sector. A broad range of investigations have taken place, and a number are on-going. DG SANTE will be reporting on biologicals and biosimilars from a regulatory perspective. The event is virtually free since it's 25 euros per person but it also includes a lunch served as it's a lunch meeting followed by the report presentation. JD: Summer is a slow time of year for lectures and such, so I have nothing planned this week. However, there’s a lot of wildlife to be seen in the area and I’m certainly going back to Point Reyes to have a look at those goldfinches, and anything else that wanders in front of my binoculars. Chris: This week I am writing about spacesuits and the full range of jobs that they perform. Some functions of them are obvious but some are less so, which is something that is not helped by the less than rigorous application of scientific principles in the television and movie making industry. I will also start turning some attention to this medium myself. I’ve long planned on producing video content to go alongside my blog and as yet never quite got around to it. I plan to start trying to be more active in pushing this project forward which is leaving me both inspired and full of dread in equal measures. <hr /> <h2>In Closing</h2> Follow the science!

Science on! <hr /> <h2>Science News with Amrita Sule and Chris MacAlister</h2> <h3>Evidence Found for a New Fundamental Particle</h3> Time for some news from the world of Particle physics. Since past couple of days news headlines have been flashing about – evidence of a new fundamental particle or how an experiment just detected a particle that shouldn't exist. What is all this fuss about and what particle is this? The MiniBooNE which is short for Mini Booster Neutrino Experiment carried out at Fermi National Accelerator Laboratory near Chicago have detected “sterile neutrinos”. Sterile neutrinos are particles that only interact via gravity and not via any other fundamental interactions of the standard model. Neutrinos in general are part of matter particles and are nearly massless. They interact through weak nuclear forces and barely interact with matter. They oscillate between three known types or flavors, electron, muon and tau. In the MiniBooNE experiment, a beam of muon neutrinos was shot towards a giant oil tank. On its way some of these muon neutrinos transform into electron neutrinos and are detected when they interact with oil molecules. These have different masses which allows their detection. In its 15-year run, MiniBooNE has registered a few hundred more electron neutrinos than expected. This could be because some of the muon neutrinos oscillate into the heavier 4 kind of neutrino – sterile nuetrino (which never interact with anything that isn’t a neutrino) and some of these got transformed into electron neutrinos which were detected by the MiniBooNE. A neutrino excess like this was 1st recorded in the 1990s Los Alamos National Laboratory in New Mexico with a different apparatus however the count wasn’t as big as miniboone. This is very exciting as it has been long thought that sterile neutrinos make up the dark matter. Detection of sterile neutrinos could take us a step forward in the direction of understanding dark matter. However, several physicists remain apprehensive and are not fully convinced as sterile neutrinos have not been detected in many other experimental set ups and the evidence of their existence has been weak. I guess we should let the physics world mull over this. <a href= "https://www.sciencenews.org/article/mysterious-neutrino-surplus-hints-existence-new-particles"> Science News</a>, <a href= "https://www.quantamagazine.org/evidence-found-for-a-new-fundamental-particle-20180601/"> Quanta</a>, <a href= "https://www.livescience.com/62721-sterile-neutrino-detected-fermilab.html"> Live Science</a> <h3>Pluto Has Dunes</h3> This story gets really interesting when you understand how dunes are made and that is that tiny, individual grains of sand get blown around in the wind until they run into something that stops them. Whatever stops them will likely stop many other grains of sand causing a mound. This mound then stops even more sand until you end up with full blown dune. So to distill this down to an equation that even can understand; sand + wind = dunes; and this is what has made it so surprising that dunes have now been discovered on the dwarf planet Pluto. Pictures from NASA’s New Horizon spacecraft taken 3 years ago have seen dunes on Pluto. This is confusing for a couple of reasons. Firstly, no one expected anything to be moving on Pluto due to the extreme cold there. Pluto is so cold that even the water there is frozen harder than rock; it’s certainly far too cold to have sand lying around. We also have a problem with the wind, or lack of. Wind is just our atmosphere moving around, but Pluto doesn’t really have an atmosphere. It has 0.0001% of the atmosphere that Earth has which means that winds on Pluto are weaker than the beer in a student bar! To put this into context, if you were to fart on Pluto this would create a hurricane the likes of which that dwarf planet has never seen; at least it would if the fart didn’t freeze the moment it left your arsehole. Pluto is so cold that it can freeze farts. And really, this is the solution the puzzle. As any school child will tell you, farts contain methane; and this is what Plutonian dunes are made of. Even if you freeze methane into individuals grains, they are still as light as air; so even Pluto’s meagre winds can shift them to create dunes. So there we have it: Pluto’s fart dune created by the lightest breezes known in the solar system. <a href= "https://www.bbc.com/news/science-environment-44317367">BBC News Science and Environment</a>, <a href= "https://www.sciencenews.org/article/never-seen-dunes-pluto-spotted-new-horizons-images"> Science News</a>, <a href= "https://www.scientificamerican.com/article/pluto-has-dunes-but-theyre-not-made-of-sand/"> Scientific American</a>, <a href= "https://www.nature.com/articles/d41586-018-05320-9">Nature</a>, <a href= "https://news.nationalgeographic.com/2018/05/pluto-dunes-methane-winds-new-horizons-space-science/"> National Geographic</a> <h3>CRISPR Gene-Editing Pioneers Win Kavli Prize for Nanoscience</h3> Do you guys know about the World Science Festival (WSF)? Happens around end of May every year. I attended it 2 years ago and was a lot of fun. It’s an excellent opportunity to hear about cutting edge research from the scientists itself. The Kavli prize which recognizes scientists for their contributions in three research areas; astrophysics, nanoscience and neuroscience and is announced every year at the WSF. This year the nanoscience committee awarded the Kavli prize for. Any guesses?? It’s CRISPR-Cas9, a precise nanotool for editing DNA; to Emmanuelle Charpentier at the Max Planck Institute for Infection Biology in Berlin, Jennifer Doudna at the University of California, Berkeley (UC-Berkeley), and Virginijus Siksnys at Vilnius University in Lithuania. CRISPR system, - is primarily used by microbes as a defense against invading viruses. The microbes record and target the DNA sequences of these invading viruses. Teams lead by duo Charpentier and Doudna and separately by Šikšnys first showed that this CRISPR system from bacteria can be used with an enzyme Cas9 to alter free floating DNA in test tubes – thus making them molecule scissors for tailoring genes. This system, has now evolved into a modern day tool for gene editing. Charpentier and Doudna were first to publish in Science hence received more attention. Bad luck for Šikšnys, whose paper was rejected by Cell even though it was submitted before those two. Nevertheless, work from all three labs set a foreground that Cas9 can be used as nano-sized scissors to selectively cut pieces of DNA. The CRISPR/Cas9 system has since then been exploited by scientists around the world to explore its potential in avenues ranging from biomedical sciences to agriculture. I came across a comment from Cori Bargmann who is a scientist at Rockefeller and a Kavli prize winner herself. She compares such prizes/awards to winning an Oscar which will push people to see that particular movie. Here a prize for CRISPR could tell the non-science community to be more informed about this as it could very well be a part of their life soon. I am sure I am not the only one rooting for a Nobel prize for CRISPR!! <a href= "https://www.quantamagazine.org/crispr-gene-editing-pioneers-win-kavli-prize-for-nanoscience-20180531/"> Quanta</a>, <a href= "https://www.scientificamerican.com/article/three-crispr-scientists-win-prestigious-award-fanning-controversy-over-credit/"> Scientific American</a>, <a href= "https://www.genomeweb.com/scan/kavli-prize-crispr-researchers#.WxIoElZKjUI"> Genome Web</a> <h3>Oldest Known Lizard Fossil Discovered</h3> In creationist news this week; evolutionists have once again changed their mind about the theory of evolution. This time they’ve change the date that they think reptiles first appeared. By how much you may ask? 10, 15 years? No, by 75 million years! Can you believe it? Well, back in the world of rational and responsible science reporting we can justify this change because we have a reptile fossil that is 75 million years older than anything previously discovered. To put this into context, it’s moved the date back from 168 million years ago to 240 million years ago. This is not a new discovery. This fossil of Megachirella wachtleri has been on the books for about 20 years already. What is new is the lizard classification. Small fossils can be trickier to work with than large ones. They are more fragile, harder to find and seem to occur less often. This fossil is half concealed in rock stopping full examination, CT scanning has finally allowed paleontologists to see the full creature. It’s not widely appreciated outside of taxonomic circles how precise the distinctions between some pretty major categories of animals is {Insert Chris’ Quiz here}. The divide between reptiles and amphibians is complicated due to the sparse fossil record at this time, that’s why the lizard classification is so important. It suggests that reptiles were around during the mass extinction that ended the Permian period. Forget dinosaurs, this was the big daddy extinction wiping out 96% of all life. There could be parallels with mammals. The dinosaur extinction paved the way for the mammals to diversify, maybe the Permian-Triassic extinction did the same for reptiles? <a href= "https://www.sciencenews.org/article/oldest-known-lizard-fossil-pushes-origins-back-75-million-years"> Science News</a>, <a href= "https://www.livescience.com/62693-mother-of-lizards-fossil.html">Live Science</a>, <hr /> <h2>Patreon</h2> I have fantastic news.

Huxley gave his first public defense of Charles Darwin’s “On The Origin of Species” when he presented his paper to the Royal Institution titled 'On the Persistent Types of Animal Life'. Later when asked why he chose this scientific theory to defend, he replied, “It was the natural selection”. ...in 1965, In a classic case of Cold War one-upsmanship American astronaut Ed White spent 20 minutes on a spacewalk outside his Gemini 4 space capsule only 3 months after Soviet cosmonaut Aleksei Leonov took a 10 minute stroll outside his space capsule. Six weeks after astronaut Ed White’s spacewalk cosmonaut Ivan Yurkenov took his Siberian husky Misha for a spacewalk and a frisbee toss. However, a malfunction in one of the Soviet’s poop bags cut short the otherwise pleasant outing. ...in 1942, Owing to the ongoing Second World War silk was in short supply, so the U.S. military needed a suitable alternative for the manufacture of parachutes. Fortunately, the newly invented material Nylon was available. And so was pilot and stunt parachutist Adeline Gray. Making her 33rd jump Miss Gray convinced the army and the navy that nylon parachutes were safe and durable. ...in 1975, the discovery of imprints of large, soft-bodied, toothless marine worms radiometrically dated to be 620 million years old, was reported in the New York Times, making them the oldest fossils in the United States. The fossils held their place until recently when another even older, toothless, soft-bodied fossil was discovered in the both the swamps of Washington, D.C., and Mar-a-Lago in Florida.

There’s not much room for a jovial attitude for this story. In the wake of health scares such as HIV, bird flu, Ebola and Zika there is a reason why governments consider a pandemic as one of the top threats to their population. The new virus on the block is Nipah. Discovered just before the turn of the century in Malaysia and Singapore, and is on the WHO priority list of emerging diseases. Recent case in Southern India: 11 fatalities & 25 hospitalisations. The symptoms: fever, vomiting, disorientation, mental confusion, encephalitis and fatal in up 70% of cases. How likely are you to catch it? Mercifully not very. The primary source of the virus is fruit bats. Other risks are from infected pigs and humans. Unlike Ebola, Nipah does not vertically transmit that easily. Why is the WHO so concerned? Due to the range of fruit bats and the potential for mutation. The risk is heightened by the lack of any cure or vaccine. <a href= "https://www.sciencenews.org/article/here-is-what-we-know-about-deadly-nipah-virus"> Science News</a>, <a href= "https://www.livescience.com/62664-nipah-virus-how-do-outbreaks-happen.html"> Live Science</a> <h3>Scientific Reports retracts paper claiming neurological damage from HPV vaccine</h3> That’s the type of story I really like seeing - it’s about a retracted study allegedly showing that the Human Papilloma Virus vaccine causes neurological damage. The paper is question was submitted and published by a group led by Toshihiro Nakajima of Tokyo Medical University, and became available online in November 2016. It describes impaired mobility and brain damage in mice given an enormous dose of HPV vaccine along with a toxin that makes the blood-brain barrier leaky. After many complaints by peers that the experimental setup of the study is flawed and the conclusions are not of sound scientific integrity, the publisher decided to retract the paper despite the disapproval of the original authors. Unfortunately, the damage might already be done, since the generally low HPV vaccination rates in Japan, had further plummeted since the conclusions made the headlines in the country. Much like what happened with the MMR vaccination rates and the retracted many years ago paper by the practice-banned MD Andrew Wakefield, whose antivax movement is single handedly responsible for the death of many people, including many children from vaccination-preventable diseases. The main opponents of the Japanese paper are currently criticizing the publishers for taking so long to investigate the publication and retract it, since its publication it’s been unfortunately already cited over 20 times and has made the rounds in public madia scaring needlessly many away from a vaccine that is able to save numerous lives from cervical cancer - a very aggressive form of the disease which is reported to affect more than half a million new subjects every year. Proud to say that one of the leading experts trying to debunk the paper is a professor from the University of Antwerp here in Belgium. Prof. Vorsters also pointed out that since there doesn’t seem to be a working method yet to counteract the antivax scare tactics, may be researchers and health professionals should rather focus on pointing out the usefulness of vaccines, rather than wasting efforts to disprove antivax claims. <a href= "http://www.sciencemag.org/news/2018/05/journal-retracts-paper-claiming-neurological-damage-hpv-vaccine"> Science</a> <h3>Asteroid: Stolen From Another Sun?</h3> Another month, another intergalactic visitor. But whereas Oumuamua was a tourist just passing through, asteroid 2015 BZ509 appears to be a bona fide immigrant to our solar system. I want to take you on journey with me, of skepticism. When faced with a headline like this, my first thought is “How can anyone possibly draw that conclusion about a piece of rock orbiting our Sun?” Oumauamua was fine; it came from outside the solar system a swiftly pissed off again, but a resident asteroid? My doubts were not helped when I found out that this conclusion is based on the asteroids retrograde (i.e backwards) orbit around the sun that seems to last the same time as Jupiter’s. That doesn’t seem like much to go off. Now comes the modern day black magic; computer modelling. These models attempted to recreate the conditions that would allow this kind of orbit to form. The most surprising result from this model is that it suggests that the orbit has most likely been established for about 4.5 billion years. 4.5 billion years ago the planets themselves were only newly formed and as such it is not expected that there would be any resident retrograde orbits. Put all of this together and the most plausible explanation appear to be that a passing visitor has been caught in the gravity of our young solar system and has remained here ever since. <a href= "https://academic.oup.com/mnrasl/article/477/1/L117/4996014">Royal Astronomical Society</a>, <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-solar-system-immigrant-20180521-story.html"> LA Times</a> <h3>How birds may have escaped the dinosaur-killing asteroid impact</h3> This story is a tribute for ‘the ones who made it out’. Recent re-evaluation of plant residue and fossil data shows that the birds might have escaped a narrow mass-extinction when the asteroid which killed off most dinosaurs hit Earth. We know that the Cretaceous era asteroid wiped out most dinosaurs, but we don’t rly think that it actually killed off 3/4s of life in general - including plants. This new look into the data led Daniel Field at the University of Bath in the UK to hypothesise that the birds that made it out of the extinction were in fact the ground-dwelling ones - ancient ancestors of ducks, chickens, and ostriches for example, while the ones whose species perished were the ones relying entirely on vegetation for food, shelter, nesting… Two types of data hinted to the conclusion - one showed that the lineages of today's ground-dwelling birds are much more vast than the ones living in/on vegetation, but also the fact that in fossils layers laid immediately after the asteroid impact, almost entirely seeds of plants belongs to only a small number of species of ferns. Once the forests developed gradually again, they presented a massive free ecological niche, which was taken once more by birds choosing to make use of these new habitats. <a href= "http://www.bbc.com/news/science-environment-44226534">BBC News Science and Environment</a>, <a href= "https://www.nature.com/articles/d41586-018-05228-4">Nature</a>, <a href= "https://news.nationalgeographic.com/2018/05/dinosaurs-asteroid-birds-forests-fires-paleontology-science/"> National Geographic</a>, <a href= "https://www.sciencenews.org/article/how-birds-may-have-escaped-dino-killing-asteroid-impact"> Science News</a> <hr /> <h2>A**hole of the Month</h2> When I first got the idea for the A**hole of the Month for the month of May I initially had one person in mind, a member of the United States House of Representatives. Specifically, a member of the House Committee on Science, Space, and Technology. But the more I read about this, the more I realized that the entire Republican-side of this committee is one colossal, flatulent asshole. To be fair, there are Democrats on the committee, but they lack any real power since they’re the minority party, are probably as aghast and incredulous as I am. It’s the Republicans on this committee...let me repeat the name of that committee. It’s the Committee on Science, Space, and Technology. These Republicans wouldn’t know science if it came up behind them and bit them on their collective ass. One thing I can guarantee, by the way, is that if we continue on the path recommended by this committee..science will indeed bite us all on the ass, for many generations. Last week this committee held a hearing on how technology could be used to help us adapt to climate change. One of the experts at the hearing was Philip Duffy, who is the president and executive director of the venerable Woods Hole Research Center in Massachusetts. His is also a former senior adviser to the U.S. Global Change Research Program. Dr. Duffy served as a Senior Advisor in the White House National Science and Technology Council, and as a Senior Policy Analyst in the White House Office of Science and Technology Policy. He’s held senior research positions with the Lawrence Livermore National Laboratory. And he holds a Ph.D. in applied physics from Stanford. The guy has science chops, in a big way. So, a lot of the questions and comments at this hearing were directed toward Dr. Duffy. Representative Lamar Smith of Texas showed a chart which showed that rates of sea-level rise have only increased slightly compared with the rate of fossil fuel use. To which Dr. Duffy pointed out that the chart was from a single tide gauge station somewhere near San Francisco, and that sea levels worldwide rise at different rates. Strangely enough, Representative Smith somehow forgot to show any charts or graphs that reveal rising atmospheric CO2 levels or temperatures, both of which have climbed at a steady rate in recent decades, right in line as fossil fuel emissions have increased. So in response to the chart Dr. Duffy replied, "The rate of global sea-level rise has accelerated and is now four times faster than it was 100 years ago.” A smug Representative Smith asked."Is this chart inaccurate, then?" To which Duffy replied, "It's accurate, but it doesn't represent what's happening globally; it represents what's happening in San Francisco." Rep. Dana Rohrabacher of California said he was concerned that established climate science (read that as actual science, and not made up bullshit)... he said he was concerned that science has not been questioned more by the committee. This is a committee, by the way, which has accused federal climate scientists of fraudulently manipulating climate data and has even subpoenaed their records. But the biggest blast of antiscience flatulence came when Representative Mo Brooks of Alabama questioned Dr. Duffy on the various factors that cause sea level rise, you know, peer-reviewed, testable, and repeatable science. Instead he offered his own ideas as the why sea levels are rising. Brooks actually put forth the proposition that erosion is a key factor in sea-level rise. He said the California coastline and the White Cliffs of Dover tumble into the sea every year, and that contributes to sea-level rise. He also said that silt washing into the ocean from the world's major rivers contribute to sea-level rise. "Every time you have that soil or rock or whatever it is that is deposited into the seas, that forces the sea levels to rise, because now you have less space in those oceans, because the bottom is moving up." Duffy responded: "I'm pretty sure that on human time scales, those are minuscule effects." I might add that we know the seafloor spreads at the mid-ocean ridges, and that seafloor is dragged back into the mantle at subduction zones. Mountains rise, they get eroded, the earth’s crust spreads and it gets drawn back inside the mantle. Oh, and the earth is billions of years old...not 6,000 years. Brooks doubled-down on his ignorance. Remember, this guy is a member of the Committee on Science, Space, and Technology. He doubled-down by saying that Antarctic ice is growing. To which Dr. Duffy replied, "We have satellite records clearly documenting a shrinkage of the Antarctic ice sheet and an acceleration of that shrinkage," Brooks, arguing with the scientist countered, "I'm sorry, but I don't know where you're getting your information, but the data I have seen suggests…” Duffy interrupted, informing Brooks of his sources, "The National Snow and Ice Data Center and the National Aeronautics and Space Administration." As an aside, earlier this year, NASA researchers determined that Antarctica's ice loss has accelerated in the last decade. Sea ice extent at both poles were at record lows last year. There was another representative that brought up the notion that scientists in the 1970’s believed the earth was cooling. This is a widely believed meme by the antiscience fringe that’s based on a fake Time Magazine cover from the 1970’s. That’s right I said FAKE. It was fake. It didn’t happen. It was a fake cover that suggested scientists were really concerned about global COOLING back then. They weren’t. Other media outlets picked this up and and ran with it like it was real. It wasn’t. It never was. And there are even more morons today who cite that as evidence. The only thing it’s evidence of is science illiteracy, an abject failure of basic education. Actual science from the 1970’s — certainly not as comprehensive today’s science on the subject — in reality was sounding the alarm about just the opposite idea, that global warming is what we need to be concerned about. Even in the 1970’s the idea of global warming was not new. It was already decades old.

It was titled “Developing and evaluating solutions-based approaches for mitigating global change impacts in aquatic ecosystems”. The speaker was David Koweek, Postdoctoral Researcher, Global Ecology, Carnegie Institution for Science. It presented some interesting strategies for dealing with issues such as apoxia, and lowered pH as a result of anthropogenic global warming. They have these lectures on Wednesday afternoons at the Marine Lab, which is located in a stunning setting on the Sonoma coast. I may attend these a lot more often. Go birding in the morning. Crab sandwiches at Spud Point Marina for lunch, a little more birding, attend a lecture. Sounds like retirement to me. JD: Next week I’m attending a talk at the California Academy of Sciences in San Francisco titled “Are We Alone in the Universe?” The speaker is Lisa Kaltenegger of Cornell University. She’s gonna discuss exoplanets and how we can determine which ones might be suitable for life, as well as techniques and future missions that could detect life on these worlds. Chris: I visited a laboratory trade show for the first time last week which was a truly eye opening experience. I’ve been celebrating practical microbiology by running a charity beer festival and I’ve been exploring the rather trivial question of whether God exists on the blog. Chris: This week I have an ISO17025 assessment at my lab, this is the international standard for testing and calibration laboratories. I will also be getting ecological with Matilda. We joined the RSPB at the weekend and we shall be making the most of their support to explore the living world around us. <hr /> <h2>In Closing</h2> Until next time...follow the science!

069: Talking LOUDLY About Sea Level Rise
<h2>On This Week’s Show</h2> <ul> <li>Megafauna</li> <li>Also, Mount Kilauea is still at it...now with a another thing to worry about</li> <li>Ebola is back in the news</li> <li>I gotta a gut feeling about one of these stories</li> </ul> And let’s not forget the Climate Lounge with Tom Di Liberto <hr /> <h2>Science News</h2> <h3>Diverse and abundant megafauna documented at new Atlantic US Marine National Monument</h3> Did you know today is the International Biodiversity day? And this story touches on the biodiversity of our vast oceans and deep seas. To my understanding, documenting deep-sea marine life can be extremely challenging. Often times, marine biologists have to go aboard an airplane to survey some of these regions. One such hotspot which was surveyed recently, lies on the edge of the continental shelf, where the shallow seas off New England drop sharply into the deep waters of the northwestern Atlantic. This region is called as Northeast Canyons and Seamounts Marine National Monument and is the first American marine national monument in Atlantic waters. this status was designated by President Obama in 2016. I think of it as when a park or a forest area is given a national park status. So it’s seems pretty important to me. Scientists from the Anderson Cabot Center for Ocean Life at the New England Aquarium have surveyed this region aerially three times, since the Summer of 2017. On their latest survey they observed hundreds of Bottlenose dolphins, dozens of whales including the rare Sowerby's beaked whales and dolphins of various species. These scientists find that such abundance of marine fauna is extraordinary for such a small area. These aerial sightings will help them to study how different species use this biodiverse habitat at different times of the year. These waters, which harbor wide diversity of corals, deep water fishes, and invertebrates FORM a FRAGILE ecosystem which needs to be well protected. But you see, new policies recommend that such waters should be opened for offshore drilling which is NO GOOD for the precious marine life in waters like Northeast canyons. <a href= "https://www.sciencedaily.com/releases/2018/05/180516172249.htm">Science Daily</a> <h3>Hawaiian volcano spews ballistic blocks</h3> I first read this story title as ‘Hawaiian volcano spews ballistic bollocks.’ I did. My first thought was, therefore, oh. Is that literal? What does that even mean? My second thought was ‘ah, I can’t read! Wonderful! Writing my thesis is going to be so much fun!’ But what are ballistic blocks? (And ballistic bollocks). They are, terrifyingly, just massive chunks of rock the size of appliances. Not ideal. These are being chucked out by Kilauea, the volcano that has been in a state of continuous eruption on Hawaii since the 80s. The caldera (bowl where the lava pools) is deflating, increasing stress at the volcano base. There have been 4.4 magnitude earthquakes. The ash plume can be seen from the ISS. This ash can obviously cause health issues when it’s breathed in. The locals also have to contend with VOG. That’s some sort of horrible gas mix that has sulphur dioxide - highly toxic - mixed in. So we spoke about Kilauea recently but the Hawaiians’ problems are going nowhere for now! <a href= "http://www.bbc.com/news/world-us-canada-44152515">BBC</a>, <a href="https://www.popsci.com/kilauea-mount-st-helens">Popular Science</a> <h3>Congo confirms first urban Ebola case, raising possibility of ‘explosive increase in cases’</h3> Ebola, a word that we wish to hear no more. But it has resurfaced again, this time in Congo in the city of Mbandaka, home for 1.2 million people. Congo health officials reported that so far there have been there have been 44 suspected cases of Ebola since April and 25 people have died. The disease causes internal bleeding and is transmitted to humans through the consumption of contaminated meat or close contact with an infected person. This makes it extremely difficult to contain Ebola in an Urban setting like Congo, as the number of contacts can amplify much quickly. Also, the city of Mbandaka lies on the bank of the Congo River which is frequently used by the local people for transportation, increasing the chances of the virus spreading down the river over long distances. Ebola epidemic which first started in 2014 in West Africa was worst ever recorded and resulted in infecting more than 28,000 and killing more than 11,000. The WHO was blamed then in part for not acting on time. However, this time WHO is doing everything to contain this outbreak before it gets out of proportion. A vaccination drive has begun on Monday in the city of Mbandaka. More than four thousand doses of an experimental Ebola vaccine developed by Merck have been shipped to Congo. This is an experimental vaccine which proved quite effective in Guinea in 2015-2016. Their game plan is that, Whenever a new Ebola case is diagnosed, all the people who might have a made recent contact with the affected individual will be traced and vaccinated so the disease remains contained. We’ll just have to wait and watch how this plays out. But most importantly we should take a pause and appreciate the health workers and doctors without borders who are volunteering in this hard hit area for all their hard work. <a href= "https://www.washingtonpost.com/world/first-confirmed-urban-ebola-case-is-a-game-changer-in-congo/2018/05/17/430babce-5890-11e8-9889-07bcc1327f4b_story.html?noredirect=on&utm_term=.5e7f2a1e2dd0"> Washington Post</a>, <a href= "https://www.npr.org/2018/05/18/612240853/who-and-congolese-officials-scramble-to-contain-ebola-outbreak"> NPR</a> <h3>How the gut influences neurologic disease</h3> We don’t give our guts nearly enough thought. I am not talking about those awful yoghurt adverts. Your gut is a hugely complex organ system which also has effects on your brain - the crosstalk between the brain and the gut is still being unravelled. A new study in Nature regarding the link between neurological disease and the gut - using a combination of human cells and animal models. There is a growing body of work on how byproducts can influence the brain - the context for this group in particular is MS. The new research, from Brigham and Women’s Hospital, focuses on the influence of gut microbes on two types of cells that play a major role in the central nervous system: microglia and astrocytes. Microglia are part of the body's immune system, responsible for scavenging the CNS - they are a sort of cleaner cell, hoovering up plaques, dead cells and other rubbish in the brain. But microglia can also secrete compounds that can damage the astrocytes - another type of brain cell, also key to maintenance and support in the brain, in different manners to the microglia. This damage to astrocytes from microglia is apparently thought to contribute to many neurologic diseases, including multiple sclerosis. However, in this paper, the team reports that byproducts that microbes produce when they break down dietary tryptophan -- an amino acid found in turkey and other foods -- may limit inflammation in the brain through their influence on microglia. So the gut *MAY* be helpful in mitigating inflammatory damage in the brain - at least in the mouse models they used, which had MS. They found evidence for the same sort of pathways in human brain samples. <a href= "https://www.sciencedaily.com/releases/2018/05/180516131209.htm">Science Daily</a>, <a href= "https://www.nature.com/articles/s41586-018-0119-x">Nature</a> <hr /> <h2>The Climate Lounge</h2> <h3>National Park service quietly releases Sea level Rise projections.</h3> <h3>Let’s talk LOUDLY about it!</h3> Earlier this year, drafts of a report on sea level rises impact on national parks became public mainly for what had been taken out of them... The one thing just so happened to be the main thing that was causing sea level rise in the first place. Climate Change. Yup, every mention of human caused climate change was removed. It’s like taking a running leap into thorn bushes thinking that if I just close my eyes at the end, the thorns will disappear. The thorns won’t disappear. Because that’s a stupid way of thinking. Fast forward a month and a half and the report has finally been released… quietly with all of the mentions of climate change kept in it but without all of that silly little thing like publicity from outlets such as... the agency it came from… Ok, so what was this report about again that led to its “odd” treatment? It was a write up created to help 118 coastal parks across the United States prepare for the impacts a changing climate will have on the natural resources and history within those parks. How horrible right? UGH! Anywaysss, what did the report find? Not surprisingly, as global temperatures heat up, sea levels are expected to rise. And that means for many national parks located along coastlines, problems could quickly worsen over the next century. The worst hit parks are along North Carolina’s outer Banks. In particular, near the Wright Brothers National Memorial, if we continue to keep emitting greenhouse gases, sea levels could rise 2.7 feet by 2100. Nearby, large portions near the Cape Hatteras and Cape Lookout seashores would also be underwater. But that is just one park and one area. Many parks from Historic Jamestowne and Assateague Island, Big Thicket National Preserve in Texas, the Florida Everglades and Jean Lafitte National Historic Park in New Orleans and even the national parks, right here where I live in Washington DC would be pretty vulnerable. The Parks service even included a graphic of what Roosevelt Island in the middle of the Potomac River in Washington DC would look like if a category 3 hurriane made landfall. Hint, the park looks blue… because it’s covered in water. This report is just another in a long list of studies that show just how vulnerable our coasts are to a rising sea because we continue to belch greenhouse gases in the air and do little to change our ways. For instance, NOAA (in full disclosure I work there but had no hand in this report) issued a report earlier this year that simply looked at how nuisance flooding, minor floods that do little damage but are annoying and occur simply during high tides, would change in various emissions scenarios. The results were pretty shocking. For many places including San Francisco, Boston, New York, Miami, nuisance flooding, that is flooding only due to the tides could happen EVERY DAY by the end of the century if we keep emitting greenhouse gases. And these numbers could increase to over 100 days by 2040-2050, a mere 20-30 years. That’s effectively NOW for planning purposes. We’ve already done enough damage to ourselves. Hows about we finally stop it, and start getting to work on the healing process. <a href= "https://www.revealnews.org/blog/national-parks-report-finally-released-uncensored/"> Reveal News, </a><a href= "https://www.nps.gov/subjects/climatechange/sealevelchange.htm">National Park Service</a> <hr /> <h2>Pub Quiz</h2> <h3>Speaking words of wisdom, letter B</h3> <ol> <li>Africanized bees, also known as killer bees, first arrived in the Americas in what country?</li> <li>What is the class of subatomic particles in which protons and neutrons are included?</li> <li>Calculated in bits per second, this is the amount of data that can be sent through a connection.

068: Amphibians, Solar Panels, Transitional Fossils, and Richard Feynman
<h2>On This Week's Show</h2> <h3>Science News</h3> <ul> <li>Origins of amphibian-killing fungus uncovered</li> <li>How California becomes the first US state to mandate solar on new homes</li> <li>New discoveries about some ancient reptiles</li> </ul> <hr /> <h2>Science News</h2> <h3>Origins of amphibian-killing fungus uncovered</h3> This is a detective story. The chytrid fungus, also known as Bd (Batrachochytrium dendrobatidis) has been decimating amphibian populations globally for a good 20 years now after it was first discovered in dying frogs in Queensland, Australia. The fungus causes excessive skin shedding which makes the animals die of ‘thick skin’. Skin is such an essential organ to amphibians with many processes such as absorbing additional oxygen and releasing toxins. It’s a bit like amphibian eczema. The impact of the disease has been so great due to the huge amount of global trade of amphibians. With animals moving before people realised that there was a problem, by the time people noticed the problem it was already everywhere. This has made tracking its origins hard. So far the origin has been narrowed down to Asia, Africa, North America or South America. This mystery is now getting solved thanks to the combined global efforts of 10 years of field and lab work by 35 institutions. The conclusion is that the disease originated between 50 to 120 years ago in East Asia. They figured this out by sequencing the fungal DNA from within amphibian genomes. Over 200 samples were used to draw this conclusion but sometimes less than 1% of sample material gave any usable results. Understanding the origin of this disease and how it links to other similar fungi could help plan for future risks. <a href= "https://www.sciencenews.org/article/deadly-frog-killing-bd-fungus-probably-originated-east-asia"> Science News</a>, <a href= "http://www.bbc.com/news/science-environment-44075687">BBC</a> <h3>California becomes first US state to mandate solar on homes</h3> California first US state to mandate solar panels on new construction homes built after 1 January, 2020. That includes apartment buildings as well. Already state law that requires that 50% of electricity to come from non carbon-emitting sources by 2030. Critics point out that mandate to add between $8,000 and $12,000 to the cost of a home. Average cost of home in California is about $440,000, about 2 ½ times the national average. According to Energy Commission homeowners will only see an additional $40 to monthly mortgage payments. Californians pay some of the highest electric rates in the country already. However, residential customers’ monthly average bills are about $96, among the lowest in the country. How? Because California ranks 49th in the nation in per capita electricity consumption. Largely driven by the state’s strong commitment to energy efficiency, and the climate. Few people near coast have air conditioners. Cool summers. Nearly 16% of California’s electricity last year came from solar. Mandate still has to get through the Building Standards Commission. Decision later this year. Remember when I said that there already exists a state law that requires that a full 50% of all electricity to come from non carbon-emitting sources by 2030? According to the Public Utilities Commission the state will likely meet goal of 50% generation of non-carbon electricity about 10 years ahead of schedule. Currently rebuilding our home that was destroyed in the October 2017 wildfires. Are we putting solar on it? Hell yes. <a href="http://www.bbc.com/news/world-us-canada-44059865">BBC News</a> <h3>Jurassic fossil tail tells of missing link in crocodile family tree</h3> The latest missing link that has been discovered links crocodiles with the pelagosaurus genera. Pelagosaurus were reptiles of the open seas that lived for about 8 million years before going extinct about 175 mya. Whilst they would have resembled crocodiles they were more like whales and dolphins in their overall body structure. The new species is called Magyarosuchus fitosi after the amateur collector who discovered it, Attila Fitos. It is estimated to have been about 5m long. The first signs that a new species was on the cards were unusual vertebrae; these turned out to be a part of its tale fin, a feature previously only found on the Pelagosaurus. But unlike a Pelagosaurus, the creature also had heavy armour, more associated with land going crocodyliforms. Sometimes with fossils it can be challenging to work out when you genuinely have a new species on your hands, but when you have discoveries as apparent as this one there leaves very little room for debate. <a href= "https://www.sciencedaily.com/releases/2018/05/180511123231.htm">Science Daily</a>, <a href= "https://www.ed.ac.uk/news/2018/jurassic-fossil-missing-link-crocodile-family-tree"> University of Edinburgh</a>, <a href= "https://peerj.com/articles/4668/">PeerJ</a> <hr /> <h2>What The Hell Was That?</h2> This is where I’d normally put the conclusion and answer to last week’s WTHWT Since we don’t have a quorum we are going to delay the fun until next week! <hr /> <h2>This Week In Science History</h2> In a slight departure from our usual TWISH format I’m gonna to talk about one of the greatest scientists in history. 100th anniversary of the birth of Richard Feynman Was an American theoretical physicist, known for his work in quantum mechanics as well as in particle physics For his work quantum electrodynamics, Feynman, along with Julian Schwinger and Shin'ichirō Tomonaga were award the Nobel Prize in Physics in 1965. He developed the Feynman diagrams which were used as a representation for the mathematical expressions describing the behavior of subatomic particles. Feynman was also one of the great popularizers and spokespersons for science. So today I’m gonna to rattle off four selected quotes from an article this week in Science News celebrating Richard Feynman <h4>1. “There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.”</h4> An expression of the importance of atoms from the opening pages of Feynman’s lectures. <h4>2. “From my knowledge of the world that I see around me, I think that it is much more likely that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence than of the unknown rational efforts of extra-terrestrial intelligence.”</h4> That comes from a set of lectures compiled in book form as <a href= "https://mitpress.mit.edu/books/character-physical-law">The Character of Physical Law</a>, <h4>3. “I think I can safely say that nobody understands quantum mechanics.”</h4> Perhaps Feynman’s sentiment might better be expressed by saying that anyone who claims to understand quantum mechanics, doesn’t. <h4>4. “The first principle is that you must not fool yourself — and you are the easiest person to fool.”</h4> The best advice to scientists and anybody else who seeks the truth about the world. The truth may not be what you’d like it to be, or what would be best for you, or what your preconceived philosophy tells you that it is. Unless you recognize how easily you can be fooled, you will be. Bonus quote: “Physics is like sex: sure, it may give some practical results, but that's not why we do it. <hr /> <h2>Promotion</h2> <a href="https://matildaslab.wordpress.com/">Matilda’s Lab</a> <hr /> <h2>In Closing</h2> Until next time...follow the science! <hr /> This episode of the Blue Streak Science Podcast comes to you from San Francisco, California; and Chester, England.

067: Volcanos, Bird Beaks, Glass Houses, and the Multiverse
<h2>Coming up on this week’s show</h2> The Climate Lounge with Tom Di Liberto The return of the What the Hell Was That game! Science News: <ul> <li>Kilauea Volcano Erupts</li> <li>How birds got their beaks</li> <li>Kew Gardens Glasshouse Reopens</li> <li>Stephen Hawking's Final Theory About The Multiverse</li> </ul> <hr /> <h2> </h2> <h2>Science News with Sophie McManus and Nevena Hristozova</h2> <h3>Kilauea Volcano Erupts</h3> Can you imagine living on top of an active volcano?! I am sure you are aware, but Kilauea has been kicking off lately. Nearly 2000 people have been evacuated around the south side of the island. They will probably move back soon, depending on developments, obviously. Move back to live on top of their active volcano. <img class="alignright size-medium wp-image-2891" src= "http://bluestreaksci.staging.wpengine.com/wp-content/uploads/2018/05/kilauea1-350x350.png" alt="" width="350" height="350" />So, what happened? A series of small earthquakes was recently followed by a quake with mag 6.9 last Friday. A new fissure then opened up and started letting out hot lava. Kilauea is one of the world’s most active volcanoes and has been in a state of eruption for the past 35 years. Tropical Visions video (co. Paradise Helicopters) is amazing to watch. It is like the cartoons of volcanoes you see as a child. Spectacular bright red lava fizzing everywhere and engulfing cars. Less appealing, by the sounds of it, are the emissions of sulphur dioxide and hydrogen sulphide. Kinda toxic. That’s why the people have been evacuated. Also the lava. A nice quote by the excellently-named Mika McKinnon, volcanologist and disaster researcher, “Hawaiian volcanoes can be extremely deadly, but it’s a hazard you can walk away from.” This explains the footage of people strolling away from the lava flows. I mean strolling as a relative term. In other Hawaiian news, Hawaii became the first state to ban sunscreens that contain chemicals harmful to marine life. Let’s hope that Kilauea calms down a bit - and that other places follow the lead on the sunscreen front. <h3>How Birds Got Their Beaks</h3> This story comes from Yale University and it’s telling us how scientists were able to reconstruct a missing link. Not between apes and humans, but between dinosaurs and birds. This bird-like dinosaur had wings and a breastbone which look very much like the ones of modern birds and it had a beak too, but very much like reptilian dinosaurs. It’s mouth was apparently full of teeth. This species is not new. It’s been known to scientists for over 150 years, but due to the bad condition of the fossils it was hard to reconstruct its head to get more details. In 2014 though, a new fossil of the Ichthyornis dispar was found and this time it had a perfectly preserved skull. A 3D reconstruction showed that it could move its upper part of the beak independently, like birds today can and reptilian dinosaurs definitely can't. The fossils also showed these indentations on the surface of the skull, which are were a rather strong set of muscles were attaching, to allow the ancient dino-bird to grab, hold on to and chew its food with the help of its sharp teeth. Having such strong muscles operate a beak that is also capable of performing some of the tasks a hand sound have also probably played a role in freeing the front limbs to be used for flight. <h3>Kew Gardens Glasshouse Reopens</h3> This is great news! A few days ago, Kew gardens reopened its glasshouse (Temperate house). It houses 10,000 plants from the ‘Goldilocks’ zone - some of these are exceedingly rare and the glasshouse represents a final refuge. I remember going to Kew a long time ago to the glasshouses. Temperate house is the world’s LARGEST glasshouse, and it is beautiful. In an interview with the BBC, the naturalist and broadcaster Sir David Attenborough said he had first visited Kew Gardens "back when it cost a penny...When I had an office job at the BBC, when I used to be stuck in the office and get really depressed, I would come here at the weekend and take a deep breath, because there was a smell of the tropics.” He reiterated the importance of such institutions in avoiding extinctions. <h3>Stephen Hawking's Final Theory About The Multiverse</h3> One of the last (so far) legacies of Prof Hawking is an article submitted just days before his passing. He has worked on this for almost 40 years and it’s a theory which tries to explain how is it possible for the Big Bang to have created an infinite number of Universes, more or less similar to ours. Originally, his work with James Hartle worked out how, based on principles of quantum mechanics the Big Bang could have potentially created an infinite number of universes; some very similar to our and others so different that even the laws of physics wouldn’t be the same. Later on, further developing the math to solve this problem, Hawking with the help of Professor Hertog from Belgium, used principles from String Theory to work out the math. By doing so, the two physicists came up to a solution according to which the Big Bang created a bunch of parallel universes, but they all have distinct similarities. Meaning that there might be a universe out there where I’m skinny and can sing, another one where dinosaurs still exist and yet another one where Professor Hawking never went to grad school but became a world famous tap-dancer! One of the implications of the theory that parallel universes emerging as a result of the Big Bang exist based on the String Theory principles rather than the quantum physics ones, is that we might be able to actually detect parallel universes, since their basic physical laws will be very similar. It’s still doubtful though that we’d be able to travel through them. <hr /> <h2> </h2> <h2>The Climate Lounge with Tom Di Liberto</h2> <h3>Thwaites Thwaites Don't Tell Me!</h3> Welcome to the Lounge! Of course, the first thing anyone gets to hear when they enter the lounge is an update on Puerto Rico. Less than 50,000 people are still without power a month before the hurricane season starts. And every week stories come out that are shocking but get completely overlooked due to the ongoing madness. For instance, did you know that the Puerto Rico Department of Public Health found that the overall suicide rate in Puerto Rico increased 29% in the first months after hurricane Maria? Or how about this quote about rebuilding Puerto Rico’s power grid from a former energy executive whose has dealt with natural disasters from hurricane Sandy, to severe storms in Jamaica to earthquakes in California, “I’ve never seen anything like that--not in a developed nation” said Ed Muller. So yeah, still a disgrace. Lately I’ve been talking about interesting research, new papers that have come out, and that has been fun. But I wanted to take you this week on a little journey to a story about getting the data needed to make cool new studies. On April 30, the largest American/British joint science expedition to Antarctica in 7 decades was launched to look at the Thwaites glacier, a terrifying “what if” glacier which if it completely melts would raise global sea levels by 10 feet. As David Holland, one of the principal researchers on this project said in an article in the Washington Post “For global sea-level change in the next century, this Thwaites glacier is almost the entire story,”. Right now, basically, scientists fear only a bump in the sea floor is helping to hold the glacier in place. But it’s hard to know how precariously things are because well... The one issue with the Thwaites glacier is that, like, Antarctica, is like, super hard to get to. This expedition will fix that. So who’s going? There will be 6, count’em 6 field expeditions going along with two computer modeling studies. And they are pulling out all the celebrity stops. One of the submersible research vessels will even be BOATY MCBOATFACE! They are going to study this glacier from all directions. Holland will be drilling holes near the grounding line (where the ocean, bedrock and ice meet), and put a remotely operated vehicle in see whats going on. Sridhar Anandakrishnan, a Penn State geoscientist will be doing seismic surveys detonating small explosive devices within the Thwaites glacier to measure the echoes of the sound waves. This will help determine what the glacier is flowing over and help figure out the glaciers rate of retreat. There will also be ships and planes with radars, and remote sensing, ocean gliders, subs and more drilling. This research expeditions will come back with an absolute treasure trove of data which can then be fed into computer models to determine better projections for what lies ahead. It’s a daunting task, in one of the most inhospitable places on the planet. But over 100 scientists are heading out because they know just how dire things will be for humanity if the Thwaites glaciers retreats all the way back to the south pole. So you know, not a heavy research trip at all. Just another walk in the glacial park…. <hr /> <h2> </h2> <h2>What The Hell Was That?</h2> We rummaged through the hallway closet and found an old game. Listen next week to see who can guess what the hell that sound was. <hr /> <h2> </h2> <h2>In Closing</h2> In 2004 when asked about his IQ, Professor Stephen Hawking replied, “I have no idea. People who boast about their IQ are losers”. <hr /> This episode of the Blue Streak Science Podcast comes to you from San Francisco, California; Cambridge, England; Washington, D.C.; and Brussels, Belgium.

Thank you, SC He brings up a good point because when it comes to grand ideas of introducing species to counter a human-caused problems our history is not so good. Examples: kudzu, the vine that ate the American south, and cane toads in Australia I’m all for tackling this critical problem in our oceans, but let’s do be cautious when it comes to unleashing microorganisms into our oceans. If you have any questions or comments you can do like SC and hit us up on Twitter, or you can email us at <a href= "mailto:feedback@bluestreakscience.com">feedback@bluestreakscience.com</a> Science News Scientists’ early grant success fuels further funding We are back with some super cool science stories to share. But wait! Do you know who are some of the show-runners who make this science possible. Grad Students and post docs definitely make it to the top of the list. As a postdoc myself I can strongly attest that, to do amazing science you need funding. So today I am going to talk about a study, which compared the career trajectory of early career scientists or post docs who are funded early on in their career versus the ones who miss out on these initial grants ONLY by a small margin. This study was led by a Dutch sociologist, Thijs Bol at the University of Amsterdam. They compiled a data set, which consisted information on funding scores as well as the grants funded from two organizations - The European Research Council and Netherlands Organization of Scientific Research. Their analysis revealed that researchers who were funded, CONTINUED to gain more than TWICE as much research funding in the next 8 years relative to their peers who weren’t funded at an early stage. And let me repeat this, the scientists who failed to secure grants - just missed it by a small margin. Similar studies have been done in the past which also had similar conclusions, but Bol claims they were not as thorough as this one. The group reasoned that this drift in the funding acquisition could be partly because researchers who lost out on the initial grant were less likely to apply for future funding. I would like to say here that, many post doctoral positions are funded through their labs/mentors/institution - that is they are not always required to apply for funding. HOWEVER, they should very much be encouraged to do so. Having you independent funding, can definitely set you up for subsequent funding in future. Which has also been shown by the study under discussion. This study only looked at data from two funding agencies, more information from other funding agencies world wide is needed to see the whole picture. I believe that a much bigger problem is, rejection of funding at an early career stage can dissuade one from pursuing science, which is a bad news for the WHOLE SCIENCE community. So what can be done? Funding agencies should be made aware of this. Also, more academic mentoring wrt to grant applications should be made available to postdocs and early career researchers. So yes -- KEEP APPLYING FOR GRANTS! <a href= "https://www.nature.com/articles/d41586-018-04958-9?WT.ec_id=NATURE-20180426&utm_source=nature_etoc&utm_medium=email&utm_campaign=20180426&spMailingID=56487811&spUserID=NzE3MDU3OTQ1MDYS1&spJobID=1383950517&spReportId=MTM4Mzk1MDUxNwS2"> Nature</a> Mysterious Ice Holes in the Arctic Living here on the west coast of North America means that whenever I travel to Europe I get to fly over the Arctic. The land and ice up there are incredibly beautiful even from 11 kilometers up. Glaciers on Greenland. Ice flows in Baffin Bay. Icebergs. I imagine all the wildlife down there... News story about some interesting phenomena up there in the ice. According to NASA, weird holes have begun to appear in the ice. They have no idea what’s causing them. John Sonntag, a scientist with NASA’s Operation Ice Bridge took some photos and found these strange holes. Some researchers have suggested these holes were created by seals. That makes a lot of sense until we find out many of the holes are quite large. According to Sonntag the holes are several meters, even tens of meters in size, making it unlikely that seals are the cause. Some have suggested that bowhead whales may be punching up through the thin ice to breathe. NASA has a monthly contest on their site called Earth Observatory, and a picture of these holes appears in their April Puzzler. Head over to the show notes for a link to this site, and perhaps you can help NASA figure out what the hell this is! <a href= "https://earthobservatory.nasa.gov/blogs/earthmatters/2018/04/17/april-2018-puzzler/"> NASA April Puzzler</a> <a href= "https://news.nationalgeographic.com/2018/04/arctic-ice-hole-photos-science-spd/"> National Geographic</a>, <a href= "https://www.washingtonpost.com/news/speaking-of-science/wp/2018/04/23/nasa-baffled-by-mysterious-ice-circles-in-the-arctic/?noredirect=on&utm_term=.ecc8556c8d0d"> The Washington Post</a>, <a href= "https://www.popularmechanics.com/science/environment/a20055205/icebridge-ice-holes-arctic/"> Popular Mechanics</a> NASA InSight Lander To Get First Look At ‘Heart’ Of Mars All this news about planet EARTH, guess who is feeling left out? Yes! You guess it right it’s planet MARS. But not to worry Mars because you will be getting a new visitor in November. A spacecraft designed to study interior structure, composition as well as Mar’s seismic activity is scheduled to lift off on May 5th and land on the red planet, Mars in November. This spacecraft is called INSIGHT, which is short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. <img src= "https://assets.libsyn.com/secure/show/50742/MarsINSIGHT.jpg" alt= "" width="400" height="225" /> INSIGHT will be the first spacecraft to land on Mars since Curiosity in 2012. The lander, rovers and orbiters that have visited mars before investigated MOSTLY the surface history by studying features like canyons, volcanoes, rocks and soil. INSIGHT will be digging in deeper to learn about the RED planet’s formation and give us more “Insight” about what lies under it’s surface. Lets’ what what exactly will be the job of this spacecraft. The INSIGHT mission will operate for approximately two earth years and during that time it will use primarily 3 instruments. A seismometer will pick up the vibrations from marsquakes, which are Mars equivalent of earthquakes. Insight will also hammer a heat-flow probe upto 16 feet deep into Martian surface, which is deeper than any of the probes used before. This will reveal how much heat is flowing out of the deep interior of the planet. And the third instrument known as RISE will track the location of the spacecraft and monitor minor variations in its position, to determine just how much Mars' North Pole wobbles as it orbits the sun. These experiments will tell us about things like; if Mars formed from the same stuff as Earth and the Moon, what is it’s core made up of and also give a sneak peek into how the planet evolved. In the coming months we will hear more about this mission as the lift off takes place later this week from WEST coast of United States. Just a note – this is the 1st time an interplanetary mission is being launched from the WC. Also, if you are in the area and would like to lean more about MARS INSIGHT mission, you should check out the MARS road show this week as well as next week in California where you chat with NASA scientists and engineers, and learn about INSIGHTS MARS mission in detail. <a href= "https://mars.nasa.gov/insight/participate/roadshow/">Mars Roadshow</a> <a href= "https://scienceblog.com/500527/nasa-insight-lander-to-get-first-look-at-heart-of-mars/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+scienceblogrssfeed+%28ScienceBlog.com%29"> ScienceBlog</a>, <a href= "https://mars.nasa.gov/insight/">NASA.gov</a>, <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-mars-insight-20180330-story.html"> LA Times</a> The Climate Lounge Puerto Rico still suffers from occasional island wide black outs. The hurricane season officially begins in a month. Hurricane Maria hit the island on September 20… This continues to be awful. Sometimes we all just have one of those days, you know. Just BAD days. Where nothing seems to be going in your favor. Then you turn on the news and you realize that things are going in ALOT of people’s favor. Ugh, just bad days. Maybe you’re like me when those days happen, and you close your eyes tight and try of think of anything else. Like what would time period would I go to if I could time travel. Or What would the world be like if we still were just one big super continent? Or better yet, what would life be like if I was 6 feet tall? THESE ARE IMPORTANT QUESTIONS. Well, some scientists from the Max Planck Institute just lived my dreams. They presented their findings recently at the annual meeting of the European Geosciences Union on what earth would look like if it spun the other way. I sincerely hope my excitement is coming across to everyone listening right. THIS IS SUCH A COOL THING. We often talk about our climate as latitudinally dependent because that’s sort of an easy way to look at things. It’s warmer near the equator and colder near the poles. Or we talk about it with regards to elevation The higher you are, the colder it is. But we don’t talk about just how important the earth’s rotation is in causing the regional climates all across the world. But these scientists did just that. Florian Ziemen of the Max Planck Institute of Meteorology in Hamburg, Germany was the lead scientist on the work and he and colleagues tweaked some parameters in a climate model that effectively turned the planet around. They then watched to see what climates developed as the model ran for 7,000 years. This meant that they stopped the movement of air and water then reversed the direction of the Coriolis force which essentially reflects the impact a spinning earth would have one the movement of liquids and gases on our planet. They even reversed the direction of the sun so that, for instance, NY is 5 hours ahead of London in this bizarro world. The result, things got crazy! The world’s deserts completely shifted. The Sahara desert was gone. It was now much wetter along with the Middle East. Instead, deserts reigned over the southeast United States and Brazil, Uruguay, Paraguay and Argentina. Australia also became much wetter as a reversal of the winds brought more moist air onshore. In total, a backwards earth had 11 million square km’s LESS desert than our current earth. For me on the Atlantic coast of the US, our climate became more mild and wet. While severe winters slammed western Europe. But it wasn’t all great. Huge blooms of cyanobacteria took over northern Indian ocean. It’s a whole new world. But this doesn’t explain why scientists do this. Well, looking at a retrograde planet earth allows scientists to see if our understanding of the earth is actually correct. For instance, scientists use these experiments to look at this like the huge ocean circulations on the planet. There is ongoing research looking into just how deep water forms that is waters that sinks to the bottom of the ocean which currently occurs in the north Atlantic. In prior backwards moving planet experiments, this formation of deep water either broke down or continued, leaving scientists perplexed. If this formation didn’t stop, then the shape of the ocean basin might be playing a role. If it did collapse so does that argument. This most recent research did in fact have deep water formation collapse, similar to work done in 2008. So would the earth be better if things turned backwards? Well, it would be greener, less desert-y but it all sort of depends on where you live. And truth be told, it’d still be full of humans and for all of the amazing things humanity has accomplished, we still have a knack for screwing things up. <a href= "https://eos.org/articles/reversing-earths-spin-moves-deserts-reshapes-ocean-currents"> EOS</a> This Week In Science History This week in science history on 26 April in 1986, in Pripyat, in the northern Ukrainian Soviet Socialist Republic, now thankfully called just Ukraine, one of the four reactors at the Chernobyl nuclear plant exploded during a safety test, launching a cloud of radioactive dust over Europe. The Soviet Union, always concerned with public health and transparency, announced the explosion two days after it happened. Did you know I’ve been to Chernobyl? Yep, I can count on the fingers of my left hand how many times I've been there. Seven times. This week in science history on 26 April in 1884, the New York Times reported that “sending mails by electricity” was to be investigated by the Post Office Committee of the United State House of Representatives. The article suggested it could lead to ten cent telegrams, million dollar offers from Nigerian princes, and pills to enhance your manhood. This week in science history on 27 April In 1887, surgeon George Morton performed the first appendectomy in the United States, saving the life of a 26-year-old man suffering from a toothache. This week in science history on 30 April in 1878, Louis Pasteur lectured at the French Academy of Science to promote his germ theory of disease. Predictably, he still met with opposition from some scientists, and he replied that their skepticism was “fatal to medical progress”, thus proving that old microbiologists never die, they’re just put out to Pasteur.

065: Plastic-eating Bacteria to the Rescue
Plastic-eating Bacteria to the Rescue? Chris: [Ladies and gentlemen, we are at war! I’m not talking about a war on terror, a rogue state or even drugs, I’m talking about something much closer to home. I’m talking about plastic. Plasti-phobia is very popular at the moment; in the last week alone the UK government have announced a policy to ban the use of plastic straws in pubs, clubs and restaurants as the national still reels from the images shown in the stunning Blue Planet 2 series. And right here on Blue Streak Science we spoke a couple of weeks about a giant island of plastic adrift on the ocean, spreading micro-plastics far and wide and into the food chain. The reason that this war on plastic is so hard to win is that, despite these increasingly apparent environmental impacts, we just can’t quit it. It’s a bit like a guilty affair; we know that it’s reckless, irresponsible and hurts others but it’s just so convenient and easy. Especially for us in the world of science and laboratories; with our disposable pipettes tips, Petri dishes, deep well plates and culture loops. We’ve been as much a part of the problem as we have the solution. Up until now that is. The biggest problem that plastic presents is also its greatest asset; its resistance to biodegradation. But this resistance is starting to be ground down. In 2011 a single-celled fungus called pest-alo-tiopsis microspora was discovered which can digest polyurethane and in 2016 a strain of Ideonella Sakaiensis bacteria was identified that eats PET. This bacteria was found outside a plastic recycling plant in Japan. What amazes me about this is just how quickly these organisms have evolved to exploit this new food source. We talk about antibiotic resistance as being a fast process but antibiotics are, for the most part, still going strong 100 years after their discovery. Plastics have been with us for half of that time and we’re already seeing this shift in our microflora. So how are scientists helping with this? Well, if you give scientists the novel enzyme that is responsible for the breakdown of PET (rather imaginatively called. PETase, we don’t mess around with naming here. We call a spade a digging tool and a rose by any other name would be Rosa kordesii and it would not smell so sweet as the cross breed known as Louise Odier because science is complicated enough without adding a bunch of artsy-fartsy names to the mix that don’t mean anything). But I digress; if you give scientists a novel enzyme (like PETase) then they will do what scientists do and dick around with it. Prof. John McGeeham and Dr. Gregg Beckham of the university of Portsmouth and NREL, respectively, have managed to not only make PETase more efficient but have also widened the range of plastics that it works on. They didn’t initially set out to tweak the enzyme in this way; they were merely attempting to look at its crystal structure. Knowing this would allow the enzyme to be synthesised in the same way as ones that are already being used in your laundry detergent. It was during this synthesis that the error was made, resulting in a more efficient enzyme that can now be produced to aid the plastic recycling process. Where will this take us in future years? With the microbial world churning on, who knows, maybe one day plastic will end up being no more durable than cardboard. We’ve certainly left enough of it around for the bugs to practice on!] <a href= "https://www.theguardian.com/environment/2018/apr/16/scientists-accidentally-create-mutant-enzyme-that-eats-plastic-bottles?CMP=Share_iOSApp_Other"> The Guardian</a>, <a href= "https://www.sciencenews.org/blog/science-ticker/plastic-gobbling-enzyme-just-got-upgrade"> Science News</a>, <a href= "http://www.pnas.org/content/early/2018/04/16/1718804115#ref-17"> PNAS</a> “Warm Transplants” Save Livers and Lives Nevena: [Few months ago we spoke of artificial womb and how the first lamb which was carried to term in one was the proof of concept that we might be well on the way to assisted pregnancies, when for health reasons the mother might not be able to carry the fetus to the end of the necessary period. This story, published in Nature, is about slightly different type of womb-like device. One that can help transplantation organs to reach the patient in better condition and increase the chance of the transplantation procedure being successful. There are many hurdles to a successful transplantation of organs - often times the storage of the organ between the donor and the recipient ends up damaging the organ to an extend which increases the risk of it failing and being rejected by the patient. Now a new device which has been tested in the randomized clinical trial described in the nature paper authored by Dr David Nasralla and his colleagues, was shown to increase the success rate of liver transplantations. One of the main differences with previous storage devices is that in keeps the organ at 37 degrees C (the body temperature of a healthy human). So far, transplant organs are always kept on ice (4 degrees C). While there are many rational reasons keeping on ice organs taken out of the body of donors makes sense, it might actually not be the most optimal way to do it. Putting tissues and organ on ice for example can reduce the development of bacterial contaminations, it also is thought to induce the cellular chaperones - types of proteins which have the sole purpose of protecting the cells against stress (and if removing organ from its place is not stress, I don’t know what is). But it might appear that at least in the case of liver, putting it on ice it might damage the organ more than protect it. The machine that was developed to try and remedy this actually supplies the liver with blood saturated with oxygen - lack of oxygen is one of the main reasons that tissues and cells fail. It also filters out immunogenic cells so as little as possible risk there is for immune response in the receiver of the organ and rejection. Additionally, the machine is equipped with a bunch of sensors which measure the performance of the organ and if by any chance, for whatever reason, it starts under performing before the procedure has taken place, the doctors can decide based on this information whether or not they should discard the liver or if it is safe to proceed with the transplantation. At this point the downside of the machine is its price - soaring to as much as 8000 euros, this is virtually unachievable tag for most patients and it can hardly be covered by national health insurance programs. But like all other tech, the hope is that the price tag will quickly start showing lower numbers as ways are established to use more sustainable and cheaper materials without sacrificing the performance of the machine. ] <a href= "https://www.nature.com/articles/d41586-018-04816-8?utm_source=briefing-dy&utm_medium=email&utm_campaign=20180301"> Nature</a>, <a href= "https://www.nature.com/articles/s41586-018-0047-9">Nature (original abstract)</a> Ibuprofen and acetaminophen (paracetamol) reduce dental pain more effectively than opioids Chris: [Elvis Presley, Prince, Hank Williams, Heath Ledger, Sigmund Freud; these are just a few examples of high profile people who we have lost as a result of opioid abuse. These tragedies occur because these highly addictive substances are available, legally, as they are such effective painkillers; but a new study has concluded that they are not as effective as their less dangerous alternatives, ibruprofen and paracetamol. Could it be that these celebrities’ lives could have been saved if we had known this earlier? Well, only if they had been suffering from toothache. This unexpected discovery comes after a wide literature review. Anita Aminoshariae is one of the study’s authors and explained that the aim was to create a compendium detailing both the benefits and harms of these medications as a resource for dentists to use in their clinical decision-making, and this resources says, don’t get your patients high! Considering the consequences that opioid use can have, it is somewhat less surprising to find that the use of ibruprofen (either with or without paracetamol to assist) produces less adverse side effects as well as being more effective at managing the pain. The reason why opioids are such a big problem is that they a part of the same family of chemicals as endorphins and dopamine that our bodies naturally create anyway. Medicinally, this is great because they can act on the brainstem and spinal cord like an endorphin (but much more powerfully) where they can suppress pain. The downside of this that it also affects the limbic system. If you have heard of endorphins or dopamine before then you’ve probably heard that they are the thing that makes us feel good; like chemical happiness. On the face of it, this may not seem like a bad side effect, to feel happy and relaxed about everything but the consequences are all too real. It has been said that humanity only ever suffers from one addiction, opioids. Everything that we get addicted to, be it gambling, alcohol, sex, chocolate or building spreadsheets (maybe that’s just me) these things all prompt our body to make these chemicals. All these other addictions are just the lengths that we go to to feed our opioid habit. The problem with these medicinal opioids is that you cut out the middle man and just provide the brain with an artificial alternative much more potent than anything than your body can make. Just think about it; once you’ve got used to the experience of an opioid high, a genuine, natural feeling of euphoria would just feel lacklustre. Ibruprofen, on the other hand, is an anti-inflammatory drug. Swelling is a normal response of the body to trauma but it can also be painful. Whilst the swelling is functional and can aid the healing process, it is possible to use these drugs to reduce the swelling and relieve the discomfort. Their effectiveness can be further improved by combining them with paracetamol. Also known as acetaminophen, it may come as a bit of a shock that no one actually knows exactly how it works. The leading theory is that it blocks the brain’s ability to detect prostaglandins which are a bit like anti-opioids; they make us feel pain rather than elation. This is the same chemical that causes swelling, so ibruprofen inhibits its production and then the paracetamol limits the brains ability to pick up on what’s left. Maybe this is why this result has been discovered. There are no nerves within teeth themselves, but they are attached to some. Dental pain is often associated with swelling and pressure on these nerves. Whilst opioids will dull this pain and make you feel a bit better about it, ibruprofen will actually do something to ease the source of the pain. But not the pain in your soul; for that that I’m afraid that you’ll just have to stick with opioids and all of the risks that they entail.] <a href= "https://scienceblog.com/500389/ibuprofen-acetaminophen-more-effective-than-opioids-in-treating-dental-pain/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+scienceblogrssfeed+%28ScienceBlog.com%29"> ScienceBlog</a>, <a href= "http://thedaily.case.edu/study-ibuprofen-acetaminophen-effective-opioids-treating-dental-pain/"> Case Western</a>, <a href= "http://www.sci-news.com/medicine/paracetamol-ibuprofen-opioids-acute-dental-pain-05931.html"> Sci-News</a> TESS in the search of exoplanets Nevena: [It seems like yesterday when the SpaceX’s Falcon Heavy rocket blasted Elon’s red Tesla roadster into space, but in the meantime the Falcon 9 (it’s smaller buddy) is busy with to serious space business delivering payloads into Earth’s orbit and beyond for various private and public programs. It most recently brought to space a NASA probe which will search for exoplanets. The Transiting Exoplanet Survey Satellite or for short TESS is expected to deploy its solar panels as we speak and to start performing a number of internal checks before it starts collecting data. Unlike other satellites before it, TESS will orbit Earth on a never used before orbit with a complex geometry, making two orbits around us for each orbit the Moon does. While this might seem a very random orbit to choose, surely you don’t think NASA didn’t choose it very carefully! The trick with this orbit is that it’s very stable - if for some reason the satellite goes slightly out of its way, the moon’s gravity will pull it back in place and allow it to keep doing it’s thing without having to do much maneuvering itself - talk about being sustainable in space. Also, in this orbit there’s much less space junk - something we unfortunately we have plenty of (and the cleaning of which Sophie talked about in our previous episode - go have a listen if you haven’t yet!). Once in its place, the expectation for TESS are soaring - its equipment is building up on the Kepler telescope’s sensors and the hope is that it will discover even more exoplanets than Kepler ever could. Whatever TESS discovers, it will feed into the science that the James Webb telescope is expected to perform once it’s launched in 2020 and it reaches its sweet spot in space - the Lagrange point where the gravity of Earth and the Sun balance out so it can stay there and observe the deep space with the most powerful sensors we have ever made for space exploration. ] <a href= "https://www.space.com/40346-nasa-tess-exoplanet-mission-whats-next.html"> Space.com</a>, <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-tess-launch-nasa-20180418-story.html"> LA Times</a>, <a href= "https://www.sciencenews.org/article/launch-tess-nasa-boost-search-exoplanets"> Science News</a> A**hole of the Month JD: The Blue Streak Science A**hole of the Month is governor Rick Snyder of the state of Michigan. Let’s go back a few years to 2014 to Flint, Michigan. That’s when officials, in order to save money, switched the city’s water source from Lake Huron to the Flint River. Unfortunately, water from the river is 19 times more corrosive than that from the lake, according to researchers at Virginia Tech University. That sounds bad, but in and of itself it really isn’t, unless you’re piping that water through antiquated pipes. And it didn’t take long for the water started to look, smell and taste bad. The more corrosive Flint River water caused lead to leach from pipes into the city's drinking water. The immediate result was people getting rashes and hair loss from the lead in their water. The long-term effects are well-known and far more dire, especially for children. So the federal Environmental Protection Agency, the EPA, had to intervene. Also, a class-action lawsuit followed against the state’s Department of Environmental Quality alleging that they failed to properly treat the water before it was pumped through the city’s old pipes. Since that time it has been a mess in Flint. Children with astronomically high levels of lead in their blood. Residents forced to use bottled water for virtually everything. Stop for a moment, and imagine what it would be like for you to shut off your taps, all of them, and rely on water that you have to drive somewhere and physically pick up. Your drinking, cooking, bathing and showering, brushing your teeth, and even watering your garden. All of it. Water you had to schlep from a distribution center to your home. But thankfully that water was being paid for by the state of Michigan. Until now. Last week the Michigan government announced it would no longer provide free bottled water to residents of Flint four years into this public health debacle. The closure of the state-funded water distribution centers, or free PODs, happened abruptly and surprised Flint Mayor Karen Weaver. At a press conference this week she recalled her conversation with the governor, “When we talked about the PODs, the governor said we need to get over it. He said the water is testing well and we need to move on,” Incidentally, is it any surprise that Flint, Michigan is majority African American and has a median household income of about $28,000? Do you think this would be allowed to happen in West Palm Beach or Aspen, Colorado? Flint still has about 12,000 homes with tainted lead service lines that need replacing. Mayor Weaver stated, “They gave us their word that they would see us through this lead and galvanized service line replacement and that we would have PODs stay open until then, and they backed out on what they said,” According to ReWire News, locals are taking matters into their own hands as the Snyder administration once again turns its back to the plight of Flint. Local celebrities and organizations like Michigan Citizens for Water Conservation are fighting for water rights and advocating change; a young activist called Mari Copeny, started an online campaign that has raised more than $22,500 in seven days. Flint officials are threatening to sue the state, and so are residents looking for continued bottled water distribution. I don’t blame them. And for turning your back on the good citizens of Flint, Michigan...governor Rick Snyder, you are the Blue Streak Science A**shole of the Month! JD: Until next time...follow the science!

064: Astronomy Meets Biology, Harpoons and Nets
Science News Conservationists use astronomy software to save species An astrophysicist and a conservation biologist walk into a bar… No, this is not that kind of story, but a real one on how collaboration is the second name of Lady Science. A work showing how space science can be used in conservation efforts for endangered species was presented at the European Week of Astronomy and Space Science in the UnKi last week. In it, Dr Serge Wich of the Liverpool John Moores University, described how, through the power of words (!!!) he was able to land a collaboration which as a conservation biologist he never thought he would - with an astrophysicist, namely Dr Claire Burke. What happened is that, the biologist was talking to his neighbour, explaining the troubles of this research - as you do. His main issue was that protecting animals who are active at night is even harder than the ones active when there’s light. They had to rely only on secondary clues - abandoned nests, feces, leftover food etc. But this is extremely inefficient and imprecise way to estimate the number of animals from a species for many reasons. Sometimes animals migrate to new habitats (may be due to climate change) and that’s why they leave behind nest, burrows and hideaways, meaning that they are simply not there, not necessarily that they are dead. Also, it’s not always super obvious which heap of smelly poop was left by which exactly species of giant mammal for example. And counting animals with infrared cameras is often hindered by the vegetation around, which - newsflash - also emits light in the spectrum, and you also have to be rather close to be able to detect them like that, which kind of defeats the purpose. And even if you did detect something, half of the time you can’t even tell if that warm blob you see with the infrared cam is a rhino or a hippo. What happened next is called serendipity - the moment when scientists smell the word “Eureka” in the air, but know there’s a ton of work to be done before they get there! The neighbour, who unlike most neighbours in this case was actually listening to the story, had an idea. He knew that his colleagues use these types of softwares which actually could identify the size and age of far away stars from their heat signatures! So they got to work, they mounted a special infrared cam on a drone and started flying it through zoos and nature reserves and teaching the software behind it to identify one animal from the other, injured animals from healthy and recently deceased from for example asleep ones. And it worked! And it can be now used for that purpose in the wild. And this is why science is awesome! ] <a href= "http://www.bbc.com/news/science-environment-43546429">BBC Science and Environment</a>, <a href= "https://news.nationalgeographic.com/2018/04/thermal-infrared-cameras-drones-poaching-conservation-animals-spd/"> National Geographic</a> Scientists find signs of new brain cells in older adults We spoke about neurogenesis a few episodes ago when we discussed a paper that suggested we lose the ability to make new brain cells as we age. Today, the tables have turned...a new paper is hot off the press that contradicts that March publication in Nature, saying that, indeed, we can make new neurons throughout the ageing process! The new paper is published in Cell Stem Cell. SO what’s going on here? Research papers often contradict each other and our understanding of natural phenomena is a result of appraising all this different evidence. At the moment, the consensus seems to be that there is some capacity for the hippocampus to produce new neurons throughout life. Both papers involved use of post-mortem brain samples. Yet the results differ. Maura Boldrini, the lead author, suggested this may be due to different preservation techniques, as well as the fact the brains in the Nature study came from a wider variety of patients, some of whom had had conditions such as epilepsy. To look for signs of neurogenesis, the researchers hunted for specific proteins produced by neurons at particular stages of development. Proteins such as GFAP and SOX2, for example, are made in abundance by stem cells that eventually turn into neurons, while newborn neurons make more of proteins such as Ki-67. In all of the brains, the researchers found evidence of newborn neurons in the dentate gyrus, the part of the hippocampus where neurons are born. There were some differences between young and old brains, notwithstanding the abundance of new neurons in each sample - old brains had fewer new blood vessels and apparently there was less evidence of new connections between neurons (synapses). <a href= "http://www.latimes.com/science/sciencenow/la-sci-sn-new-brain-cells-20180405-story.html"> LA Times</a>, <a href= "https://www.sciencenews.org/article/human-brains-make-new-nerve-cells-and-lots-them-well-old-age"> Science News</a>, <a href= "https://www.livescience.com/62227-aging-brain-new-cells.html"> Live Science</a> Hybrid swarm in global mega-pest So this is a story from the journal PNAS (which for some reason Americans pronounce totally weird) and got covered in Science Daily. It’s about genetic mutants! OW YEAH! But not really… Well yeah, but not like the teenage ninja turtles, more like the hulk and not in a good way! Do you know which is one of the main pests against which genetically engineered crops were created? It’s the cotton bollworm, which is a b*tch of pest because it feeds on more than 100 species of plants, many of which agriculturally important and is the sole reason why some years cotton farmers in India for example loose up to 80% of their harvest and in consequence - their income. It is resistant to every pesticide in the world which is why the darned GMOs are so needed in the developing world and why some denim companies (which I will not name) are total tools for refusing to buy from Indian farmers growing GMO cotton because their western clients don’t want GMO jeans on their sorry asses! ANYHOW, the damage control only for this pest costs billions of dollars every year. The other pest in this story is the corn earworm, which is not as bad, but is still a major agri-pest. The damage it does is estimated to be only about 100 mln dollars per year, which is peanuts to what the cotton bollworm does. Here’s the horror of this story though - recently, scientists from Australia had realised that the two species of pests had met, hybridised and gave birth (figuratively speaking) to a mega-pest, which unlike the two original species who have generally different areas of spread, is both super-mean to our crops and potentially able to live just about anywhere in the world where there’s arable land! They’ve found the mega-pest hybrid in Brazil (which by the way is one of the worst places for us for this to happen as Brazil is one of the world’s biggest producers and exporters of Coffee, Soybean, Soybean, Wheat, Rice, Corn, and Sugarcane). And if this wasn’t horrible enough, it turned out that from the hybrids they studied, there were not just one new hybrid, but rather many many different hybrids between the two species. In some cases, the new hybrid had gotten almost entirely the pesticide resistant genes from the bollworm and other than that was genetically mostly earworm. Which, if we draw the short straw from this, might mean that on hybrid will be susceptible to our pesticides, but 2 will not be, and that math even I can do - it does not look good for our agricultural produce. And if Brazil does not sound concerning enough, I’m just going to say that 65% of the major crops in the USA are potential dinner for the pests and having such plethora of super-pest hybrids coming your way can be really, really bad! ] <a href= "http://www.pnas.org/content/early/2018/03/29/1718831115"> PNAS</a>, <a href= "http://www.abc.net.au/news/2018-04-06/hybrid-mega-pest-risk-to-global-food-crops/9623306"> ABC</a>, <a href= "https://www.sciencedaily.com/releases/2018/04/180406100544.htm"> Science Daily</a> This Space Junk Removal Experiment Will Harpoon & Net Debris in Orbit We have a rubbish problem in space. Literally - the atmosphere is full of space junk. Now there’s a new project to try and reduce this - time for a bit of spring cleaning of space. A Japanese experiment in space trash removal, called KITE, had to be scrapped last year due to a technical failure. The new project, RemoveDEBRIS satellite was funded half by the European Commission, and half by a consortium of 10 companies. Lots of interest in clearing the junk! But how? Fishing, basically - the project will trial nets and harpoons. “The idea is that the net, as a way to capture debris, is a very flexible option because even if the debris is spinning, or has got an irregular shape, to capture it with a net is relatively low-risk compared to, for example, going with a robotic arm,” said Guglielmo Aglietti, RemoveDEBRIS principal investigator, and director of the Surrey Space Center. He adds “The harpoon is maybe simpler...but then one might think that maybe it’s a bit more risky because you have to hit your debris in a place that is suitable to be captured by the harpoon. Clearly, you have to avoid any fuel tanks.” Clearly. The trial involves cleaning up junk the team introduced to space themselves, rather than touching existing stuff up there, for legal reasons. Tests should be complete by the end of the year. If promising, RemoveDEBRIS will be incorporated into a big cleaning mission scheduled for 2024. We have 7500 tons of space junk (40,000 fragments, estimated) circling the Earth at the moment and this seems likely to increase without concerted clean-up efforts. There have been collisions in the past and these do pose major risk to spacecraft. Funny, we humans really are messy - not just on our planet, but beyond. Not something you tend to think about. <a href= "https://www.space.com/40221-space-junk-debris-sweeper-experiment.html"> Space.com</a>, <a href= "https://www.nextbigfuture.com/2018/04/removedebris-satellite-will-test-space-junk-removal-methods.html"> Next Big Future</a>, <a href= "https://www.airspacemag.com/daily-planet/first-test-space-debris-cleanup-about-get-under-way-180968631/"> Air and Space</a> The Climate Lounge The Sahara is getting bigger… boo. Welcome to the climate lounge, where, just like our planet, I’ve programmed the thermostat to get increasingly hotter and told the servers to randomly douse some people with a bucket of water, while removing all drinks from others. You thinking that doesn’t sound like a fun place to hang out…. That’s the point. But first, PUERTO RICO. Not much more to add besides what I’ve said in the past. It’s a travesty that some people in Puerto Rico are STILL without power. Making matters more infuriating recently, was an article in Politico which went through the double standards in relief efforts between those in Texas impacted by Hurricane Harvey and those in Puerto Rico impacted by Hurricane Maria. I’m sure you can guess how. But here are some numbers from the article. Nine days after Harvey, FEMA (the Federal Emergency Management Agency) approved almost 142 million in individual assistance to Harvey’s victims. That number was 6.2 million for Marias victims. It took 10 days for FEMA to approve permanent disaster work for Texas. It took 43 days for Puerto Rico. Grrrrrrrrrr. So don’t forget! Moving onto this episodes climate story, we are staying the tropics...somewhat and talking about that big giant desert in Africa called the Sahara. In a recent article in the Journal of Climate, scientist Natalie Thomas and Sumant Nigam looked at how climate changed over Africa during the 20th century with a focus on seasonal trends over Africa. That’s the boring way of saying it. Said another way. They looked to see what’s the deal with the Sahara desert and how it’s changing. And they found some things *cue ominous music* They found that the Sahara has been getting bigger. Not only was it creeping farther NORTH but it has also been creeping southward! Even worse, the farthest creep south has been occuring during the summer season, when the bulk of the rains come to areas just south of the Sahara in a region known as the Sahel. Why is this interesting? Time to talk how deserts form. First, an important and obvious fact. Different places get different amounts of the suns energy. The equator gets the most, the poles get the least. I’ve just described for you in the simplest way possible why air moves across the planet. The earth likes to keep things in balance so it is in a everlasting battle of moving warm air to the poles. But physics makes things a bit more complicated. And we get deserts as a result. In general, alot of the world’s deserts are located at the latitude of the downward branch of a huge atmospheric circulation known as the Hadley Cell. The Hadley cell as has a couple of components. The first is rising air in the tropics along the equator, think lots of rin. The second is sinking air farther north and south of the equator around 30 degrees in latitude. As the air rises in the tropics, it hits an atmospheric wall and spreads north and south where it eventually sinks by 30 degreeds latitude. As it sinks, it heats and drys. And thus you find alot of the worlds deserts. As we warm the planet, we are expanding the Hadley Cell, meaning that the downward branch of the Hadley cell is moving north. So the northward expansion of the Sahara makes perfect sense… but it doesn’t explain the southward creeping. That goes into another oscillation known as the Atlantic Multidecadal Oscillation called Billy for short….Just kidding, making sure you are paying attention. It’s called the AMO and refers to ocean temperatures in the Atlantic Ocean. They can change from warm to cold in the north atlantic ocean during phases. The warm phase (one of which lasted from 30s to 60s) brings wet conditions to sub-Saharan Africa including the Sahel and West Africa. And the cold phase which means drier conditions (one of which last from the 70s through 2000s and included an horrible West African drought in the 1980s. This cold phase AND ties to increasing greenhouse gases likely both played a part in the drought. The signals are intertwined . If this is true, it would account for the southward creep of the Sahara into West Africa. Why is this bad? In a previous life, I used to provide weather and climate forecasts for the Famine Early Warning Network or FEWS-NET for Africa, so I am a bit familiar with this area of the world’s climate. In the summer months, West Africa sees its rainy season as the rains progress increasing northward through the summer until peaking in latitude at about 19 N in August. This peak position is located in the Sahel, an area that is “on the edge” when it comes to rainfall as it. Sometimes seasons are good, but if they are just a bit late or lower than normal, disaster can strike for farmers. It’s very very vulnerable. This research suggests that rains just aren’t making it as far north as normal during the summer, which if it continues could be devastating to those countries in the Sahel. Now here is a BIG scientific caveat with this article. And serves as a useful example of how just because a paper passed peer review doesn’t mean it’s right. Other scientists have pushed back on these results, noting how sparse and inconsistent datasets are in Africa and critiquing just how the authors calculated the AMO. This is how science works. Nothing is taken as gospel. And regardless of whether these results stand the test of time. Northern and subsaharan Africa remains incredibly vulnerable to changes in precipitation and climate change. And Africa as a continent is the least responsible for all this climate change. It’s not fair. It never will be fair. And we should help out considerably. Any other choice would be a major dick move.

Dr. Chheda is a senior co-author of a paper published earlier this month in the Journal of Experimental Medicine titled "Zika virus has oncolytic activity against glioblastoma stem cells". Not only is the research truly exciting, but it also illustrates some of the greatest characteristics of science and scientists. For example, thinking differently and quite unconventionally; in this case to attack such a complex and deadly form of cancer with a dangerous virus. In the news this week we talk about an antibody that kills 99% of HIV strains, a new subspecies of sea snake that is like a venomous seafaring banana, and why owls don't wear hearing aids. In the Climate Lounge host Tom Di Liberto explains that we may be entering a new era of rapid hurricane intensification because of climate change. <hr /> <h3>Mail Bag</h3> We received an email from Chris Ryu of the Atom Club, part of the Dorset Science and Technology Centre. Chris wrote, “Well done on a great first episode back.

Title New Antibody Attacks 99% of HIV strains New research has developed an antibody that kills 99% of HIV strains. It is composed of a triplet of three antibodies and may be more effective at knocking off HIV than any naturally occurring antibody. New Subspecies of Yellow-bellied Sea Snake is a Venomous Banana! A new and very yellow subspecies of Hydrophis platura was described from the Golfo Dulce. This unique serpent also employs a hunting strategy very different from the nominate subspecies.

057: The Return of Blue Streak Science
Long time, no see! After a long hiatus the Blue Streak Science Podcast has returned with the most dangerous team in podcasting; Sophie McManus, Tom Di Liberto, Nevena Hristozova, and JD Goodwin. We look forward to reconnecting with you, too. We are certainly a little rusty, but still this episode hits all the marks. Gene therapy for cancer, crashing space probes, body farms, and even a story about puppy dogs. And of course, Tom connects the dots between the past weeks' horrifically destructive weather and the reality of anthropogenic global warming. Oh, and Pub Quiz! It's good to be back, and even better to reconnect with our awesome audience. <hr /> <h3>Science News with Sophie McManus and Nevena Hristozova</h3> These are summaries of our discussions on the podcast. For the full conversation please listen to this episode of the Blue Streak Science Podcast U.S. Food and Drug Administration Approves First CAR-T Cancer Drug The American FDA has approved a treatment for a type of leukaemia, or blood cancer, in young people. This is a treatment with a difference - it’s been termed a ‘living drug’. How exactly does a ‘living drug’ work? It isn’t the typical pill or injection route. It uses the patient’s OWN cells - in effect, taking T cells (highly specialised cells which are involved in the body’s immune response - warriors of the immune sys) and ‘supercharging’ them before injecting them to fight the patient’s cancer. The T cells are harvested from the sick person, they are then modified in the lab - they are programmed to recognise and kill cancer cells. They are grown up in the lab and subjected to rigorous QC testing before injection into the patient. The hope is then that the genetically modified T cells will kill the patient’s cancer. 88 patients with relapsing, treatment resistant leukaemia (specifically, acute lymphoblastic leukaemia), were given this treatment, receiving injections of their own modified T cells. They were eligible for the trial because they really had no hope of a cure otherwise. Of course there has to be understanding in the patients that this therapy could cause severe side effects, basically from these modified T cells running riot in the body and doing things they shouldn’t. 88 patients were treated and 73 are in remission - their cancer has receded. This treatment, Kymriah, was developed by Novartis. They hope to have 32 treatment centres running by 2018’s end. “I think this is most exciting thing I’ve seen in my lifetime,” said Dr. Tim Cripe, an oncologist with Nationwide Children’s Hospital, at an FDA meeting on Kymriah in July. Cassini's Last Moments Today we seem to know a lot about the universe, at yet very little about our own solar system. In the case of Saturn, we don't even know much about its structure - is it really an entirely gassy giant or does it have a dense liquid core like the other giants we know? Or may be even a solid one? How long is a day on the planet? How old are the rings? What’s their origin? For the past 10 years the Cassini has been orbiting the gas giant and observing its moon to try and answer some of these questions. [caption id="attachment_2476" align="alignright" width="500"]<img class="wp-image-2476" src= "http://www.bluestreakscience.com/wp-content/uploads/2017/09/cassini.jpg" alt="" width="500" height="360" /> Cassini and Saturn[/caption] Today, Cassini is going strong on the path to its inevitable death - excitedly expected and at the same time heartbreaking. The scientists from NASA's JPL made sure that the Grand Finale (as this final stage is now called) is as spectacular and as dramatic as it possibly could. The spacecraft will take photos for the last time of Titan - the biggest moon of Saturn, whose gravity will be instrumental for the final plunge into Saturn's atmosphere. And just a day before it touches the giant planet's atmosphere, Cassini will turn to Earth one last time in an emotional goodbye, taking one last photo with its camera of everything that has ever existed and still exists today on this Pale Blue Dot. The picture of Earth will be the last Cassini takes, so be sure to look up a wave goodbye! Once all cameras are off, other sensors and measuring devices will remain functional until the spacecraft inevitably burns into the planet's atmosphere. This was the planned ending of the mission. The reasons to crash it into the planet are mainly practical and of safety considerations. Cassini is running low on fuel and keeping it going for longer will pose a palpable risk of it going out of the control of JPL and possibly crashing into one of Saturn's moons. This would be the last thing any scientist would want to see. Cassini discovered the hydrocarbon lakes of Titan or the pristine ice of Enceladus. Since we cannot be 100% sure that this will not contaminate either one with Earthly chemicals, the engineers and scientists behind the mission decided it's safest to let it burn up in the atmosphere of its ultimate target - Saturn. Once it touches the top layers of Saturn, Cassini will turn its antennae to Earth to transmit as fast as possible for as long as possible the measurements its detectors are recording. Just over 60,000km above the planet's center, the atmospheric pressure will be higher than the one of Earth and the thrusters of the craft will probably not be able to compensate. Cassini will start to tumble and we will lose contact with it for good. Within 4 minutes of the point at which we have lost contact, Cassini will melt and disintegrate in a flash of hydrogen plasma (the term burn up is technically incorrect, since Saturn's atmosphere doesn't have oxygen). Since Saturn is so far from Earth, we should receive its final radio transmission only an hour and half after it had ceased to exist. 'Body Farm' In The U.K.? So our next story is about a body farm. Yes. A dead body farm. In the UK. No, this isn’t Shaun of the Dead. Please stop eating. Side note, this BBC article starts with ‘you’re dead. Now what?’... Anyway, the question presented here is whether we need a human body farm to get up and running to help us learn more about decomposition, the processes that allow dead tissue to break down (taphonomy is the sciencey word). You may well wonder why we would really want to know about this. It isn’t just a gruesome curiosity, there are practical applications, e.g. in helping the police in solving murders. Yes, we know about processes like rigor mortis and forensic scientists can work a lot of info out from a corpse, but there are gaps in our knowledge and this of course can impact a murder investigation. BBC quote: "Exciting new data published last year in the journal PLOS One suggests that the succession of bacteria that come and go, feeding on the decaying body, may help scientists to more accurately pinpoint post-mortem interval. This discovery was made by analysing bacteria scraped from the nose and ear canals of decomposing cadavers at the world's first body farm in Tennessee." Scientists such as Dr Anna Williams of Huddersfield are pushing for a farm to help with this. She argues that forensic sciences are underfunded and says crowdfunding might be an option. Other countries, mainly the US and Australia have body farms. In the UK up until now the scientific study of taphonomy has mainly been conducted on pigs. There are obvious advantages to this, namely the fact we can get hold of more pigs to study, we can replicate conditions easily, and it’s no small matter asking a community to accept a human body farm. Doggy Sniff Test For years now, we know that the great apes do also know if they are looking at themselves in the mirror or at another ape (if they have seen themselves in a mirror before). At the same time, monkeys do fail the mirror test and so do other animals we've tested. Yet, some researchers were convinced that some animals must possess a sort of self-recognition as it was indirectly implied by some behavioral studies in the past - they just didn't know how to prove it. Now, a study was published from the Department of Psychology of the Barnard College which may have found the ultimate test for self-awareness of dogs. It does not rely on images, but on smell. While we have up to five million scent receptors, dogs can have as many as 300 million, though this varies depending on the breed. So in other words, there are certain dog breeds that have a sense of smell that is ten million times stronger than that of humans! Thus, it's no surprise after all that they'd rather rely on their better senses. The new study showed that a dog would "investigate" for longer its own smell if a certain additional odour has been added to it. In other words, if a dog is presented with its own smell only, it did not feel the need to sniff extensively to figure out where or from whom this smell came from - it knew it as its own and didn't need to look into it any longer. But if the odour was modified even slightly, the dog would spent much longer "investigating" it, allowing the researchers to conclude that it grabbed its interest more than its own pure smell. These results come as confirmation that a paradigm shift is needed when scientists conduct studies regarding animals and especially their behavior - we can no longer afford to apply human-bound standards to animals who use very different sets of sensations to go about their day. Keeping this in mind for the development of future study protocols and for the reworking of some of the already established ones will certainly bring much more interesting and relevant data when we study animals from now on. It will allow us, after all, to truly understand them better. <hr /> <h3>The Climate Lounge with Tom Di Liberto</h3> <img class="alignright size-full wp-image-2475" src= "http://www.bluestreakscience.com/wp-content/uploads/2017/09/HurricaneIrma.png" alt="" width="400" height="400" />Hurricanes, Climate Change, and The Week That Was In the US alone, the western half of the country is shrouded in smoke from over 60 wildfires, while the eastern half is either dealing with the aftermath of hurricane Harvey or Hurricane Irma. Meanwhile, Hurricane Jose is just doing a loopy-loop out there in the Atlantic. “But Tom… that’s weather” you say. “This is the climate lounge not the weather vestibule", you murmur. Ahh, but we live in a climate-changed world already. And its fingerprints are all over the place. Hurricanes by themselves don’t necessarily have anything to do with climate change. They are a natural by-product of our spinning planet and warm, moist tropics. Climate change did not CAUSE Harvey or Irma. But that is completely the wrong way to think about it. It’s like reading a book where all the characters are mentioned but at no point do you have any idea of where they are or why they are doing what they are doing. The world in which our natural climate works is one that has been changed by climate change. These storms weren’t caused by climate change, but they were made worse. Let’s start with Harvey. Harvey is one of the wettest storms to have ever impacted the US, if not the wettest. Over 48 inches (1220mm) of rain fell around Houston, Texas, flooding a third of the city. This is after Harvey caused catastrophic damage when it made landfall as a major Category 4 storm with 130mph winds, the first major hurricane to hit the US since 2005. It dropped so much rain because after landfall it stalled, barely moving for several days, opening a firehose of water onto coastal Texas. 3-day rainfall totals in Houston were larger than the previous 65-day wettest period in the city’s history! How did climate change play a part? For one, a warmer atmosphere can hold more water, which means heavier rain. It’s a pretty basic equation to determine this. It’s called the Clausius Claperyon equation. From it, we know that for every 1C of warming, the air can hold 7% more water vapor, which can be turned into rain. But it wasn’t just the air that was warm, but the oceans. The warmer than average oceans also provided a steady supply of water to be squeezed out onto the coast. The warm oceans also helped increase the strength of Harvey since warm water provides the fuel for these heat engines known as hurricanes. The same story goes for Irma. Irma was by some measures the strongest hurricane the Atlantic Ocean has ever seen. It was a category 5 storm with 185mph winds for over 30 hours straight, the longest ever...anywhere on the planet. It took advantage of warmer than average waters throughout the entire tropics, which exist in no small part to our climate-changed planet. One of the big stories with Irma will also be the storm surge. This is basically how much water is pushed by the wind and is calculated by taking the water levels at the shore and subtracting the tide. The storm surge itself may not be impacted by climate change but the sea levels surely are. Rising sea levels along the coast of Florida has already led to Miami flooding during high tide normally. Add a huge storm and you can see places flood that you just normally don’t see flood. And with huge amounts of coastal development… not good. So the next time you hear someone try to say these storms weren’t caused by climate change? Casually remind that is a horrible way of framing the question. Because these events already have happened in a climate-changed world, and climate change made things worse. <hr /> <h3>Pub Quiz</h3> Today's raucous installment of the Pub Quiz resulted in a tie between the two winners!

053: March For Science
As scientists and people who value science we are too often reluctant to brave the maelstrom of politics. It drains us of energy and time, resources that are in everlastingly short supply. We value our reputations as open-minded and neutral arbiters for evidence, so taking sides on political issues just doesn't feel right. But why does the current situation make us so angry and unnerved? It distresses us because we are passionate about science! As scientists and scientific thinkers we understand that we must be dispassionate about the data. However, that requisite detachment is limited only to the evidence. Science itself, the vocation, the way of thinking, the calling, permeates our lives and our existence. If there ever was anything worthy of fighting for it is science and reason. Here's our chance to get out of the lab and on to the streets. On Earth Day, 22 April will be the March For Science. Mark you calendars and make your reservations early. It's game on! <div class="o-article_block pb-15 pb-5@m- o-subtle_divider"> <div class="grid@tl+"> <div class="grid@tl+__cell col-8-of-12@tl+"> <div class="article-text c-gray-1"> The main march will be held in Washington, D.C., but satellite demonstrations will take place worldwide. These protests give us an opportunity to collectively voice our opposition to the silencing of scientists, funding freezes, and other White House attempts to censor climate science. The demonstrations also represent a broader call for politicians to make decisions based on evidence, rather than ideology or corporate agendas. From the March for Science website: <div class="shadow-box-blue"> <blockquote> The March for Science is a celebration of our passion for science and a call to support and safeguard the scientific community. Recent policy changes have caused heightened worry among scientists, and the incredible and immediate outpouring of support has made clear that these concerns are also shared by hundreds of thousands of people around the world. The politicization of science, which has given policymakers permission to reject overwhelming evidence, is a critical and urgent matter. It is time for people who support scientific research and evidence-based policies to take a public stand and be counted. ON APRIL 22, 2017, WE WALK OUT OF THE LAB AND INTO THE STREETS. We are scientists and science enthusiasts. We come from all races, all religions, all gender identities, all sexual orientations, all socioeconomic backgrounds, all political perspectives, and all nationalities. Our diversity is our greatest strength: a wealth of opinions, perspectives, and ideas is critical for the scientific process. What unites us is a love of science, and an insatiable curiosity. We all recognize that science is everywhere and affects everyone. Science is often an arduous process, but it is also thrilling. A universal human curiosity and dogged persistence is the greatest hope for the future. This movement cannot and will not end with a march. Our plans for policy change and community outreach will start with marches worldwide and a teach-in at the National Mall, but it is imperative that we continue to celebrate and defend science at all levels - from local schools to federal agencies - throughout the world. </blockquote> </div> </div> </div> </div> </div> <div class="js-notMobileReferredByFbTw"> <div class= "o-article_block pb-15 pb-5@m- mt-n35 mt-n25@m mt-n15@s"> <div class="grid@tl+"> <div class="full-width@tp- grid@tl+__cell col-8-of-12@tl+"> <div class="article-text c-gray-1 no-review"> ScienceDebate.org is the fiscal sponsor of The Science March.

052: Earth Sets Another Temperature Record, Scientists Reprogram Embryonic Stem Cells, Women's March on Washington
2017 is shaping up to be a pivotal year in so many ways. Basic research is suffering funding cuts, government agencies are being silenced, and changes in immigration laws threaten to drive away our best and brightest scientists. Yet suddenly there has emerged a glimmer of hope. The Women's March on Washington started on social media with those words so important in scientific inquiry, "What if?". What followed was a groundswell the likes of which have never been seen in the United States. In a few short weeks this idea morphed into the largest demonstration in the history of the nation, dwarfing the Presidential inauguration held one day prior. A few weeks ago some asked that question again on social media, this time about science. Once more the reaction was breathtaking in its speed and immensity. In just one day the March for Science Twitter account gained over 100,000 followers. Just a few days later it stands at nearly 300,000 followers. The science community, not known for its activism, is planning a march on Washington, D.C.. The date has yet to be set, but the interest is strong.

The renowned Halley VI ice base, from which the hole in the ozone layer was first detected, was already scheduled to be relocated 14 miles across the Brunt Ice Shelf because of an encroaching fissure in the ice. But a new crack has been steadily growing to the north of the base, and computer modeling suggests that it could cause a large iceberg to calve away from the sheet, which could destabilize the area. <hr /> <h3>Game Segment</h3> Pub Quiz!

The Women’s March on Washington. Hundreds of other sister marches took place around the world. The goal of this march wass to "send a bold message to our new administration on their first day in office, and to the world that women's rights are human rights." It was estimated that over 200,000 people could participate in this important statement of solidarity and democracy. As it turns out, estimates of attendance in Washington were about 500,000 people. According to an article in Fortune Magazine the nationwide total attendance of this march range from 3.3 million to 4.6 million. No other single protest event comes even close to this number in the history of the republic. Are we witnessing the beginning of a new populist movement? <hr /> The Blue Streak Science Podcast comes to you from California, Washington, D.C., and Cambridge, England.

What we don’t often consider is utilizing plants to do the job. The problem is that plants are really slow and inefficient at doing this, and aren’t able to keep pace with humankind’s capacity to foul up the atmosphere. What if we could make plants more efficient, artificially? An article from Phys.org this week discusses the recently published paper in the journal <a href= "http://science.sciencemag.org/content/354/6314/900"> Science</a> by a German research team led by Tobias Erb at the Max Planck Institute for Terrestrial Microbiology.

She takes her bucket and fills it with water and then pours it through a sieve, or perhaps she swishes a small net through the water, catching any number of small invertebrates, small fish, just about anything. Besides beginning a career as a marine biologist what she is doing is taken an inventory of the water that passed through her net. At this stage she has no way of knowing that her inventory is limited by the size of the holes in that net. However, when she grows up she’ll have a much more powerful tool to learn about what’s in our oceans. DNA, in this case environmental DNA or eDNA Seawater contains molecular evidence of the plants and animals that inhabit our oceans—tiny pieces of skin and scales, body waste, or any other cellular debris they slough off. Just like a crime scene, organisms can’t but help leaving a trace of themselves behind. When our future marine biologist sequences that eDNA she can figure out exactly what’s living in a given volume of water, without ever having to see or locate the creature which kindly donated it. In August 2007 an oil worker in the Persian Gulf saw something remarkable.

That’s a truly scary thought. It should be. Because more often than not, a diagnosis is made after it has metastasized to other parts of the body. This makes lung cancer very difficult to eradicate and is a big reason why it’s the leading cause of cancer deaths in both men and women in the United States. According to a new study led by University of California San Francisco scientists, lung cancer’s ability to spread is often because of the inactivation of a single protective protein within the tumor cells. <a style="color: #ff0000;" href= "https://www.newscientist.com/article/2114056-brain-stimulation-guides-people-through-an-invisible-maze/"> Brain stimulation guides people through an invisible maze</a> You’re stuck in a maze.

An expedition to the Chicxulub Crater at the Yucatan Peninsula in Mexico has drawn a new timeline of how the cataclysmic impact that probably killed the dinosaurs happened. The article also explains how this impact may have carved out new niches in which life could flourish, even in the face of utter destruction. An Unreliable Sink: how much longer can the Southern Ocean delay global warming? The waters of the world’s oceans have been absorbing the excesses of humankind for many decades; from billions of tons of plastic pollution, chemical pollution, all the way to the CO2 exhalations of our civilization. Much of the heat generated by the burning of coal and other fossil fuels gets absorbed up by the oceans, too. In the 16 November issue of the journal Nature is an article titled “How much longer can Antarctica’s hostile ocean delay global warming?” This article takes a deep look at past and present research of the Southern Ocean to see if its waters will continue doing us the favor of moderating global warming, and will it continue doing so in the future. <a style="color: #ff0000;" href="http://phys.org/news/2016-11-fiji-ants-farm.html">Fiji Ants Are Plant Farmers</a> I’m sure some of you have heard of different species of ant and termites that farm fungi.

045: A World War Against Science Has Begun
The war against science just got very real. But please don't despair. We now have a common mission and our goal is crystal clear. To be sure, this a major setback to science and portends some dark days ahead, but we will overcome this if we re-double our efforts to communicate science through this and every other available medium. We pledge to always be your podcast and your voice. What The Hell Was That? Have a listen to this week's WTHWT! Blue Streak Science News Roundup These are summaries of our discussions on the podcast. For the full conversation please listen to this episode of the Blue Streak Science Podcast. Researchers Clear "Patient Zero" From AIDS Origin Story The man known as "patient zero" and long thought by many to have set in motion the HIV/AIDS epidemic in North America very likely had little to do with the spread of the virus, according to a new study published the journal Nature. This study goes further and gives us a clearer picture on how HIV emerged in the United States and Canada. Why Weather is Unlikely to Significantly Affect This Year's Election From the Washington Post’s Capital Weather Gang comes an article titled “Why weather is unlikely to significantly affect this year’s election”. We are recording this episode on Tuesday, 8 November, Election Day in the United States. Yes, we're nervous. Male Contraceptive Pill Works, But Side Effects Halt Trial A recent study on male birth control has made headlines, especially in social media, and for good reason. The success rate for the contraceptive is 96%. Unfortunately, the trial was cut short even though most of the participants were willing to go on with it. World's Largest Marine Reserve Hailed As Diplomatic Breakthrough Last week we got news that the largest marine reserve in the world, protecting much of Antarctica’s Ross Sea, has been created through an agreement signed by 24 nations and the European Union. This is the first time in history that countries have come together for this type of agreement. The Ross Sea is a deep Antarctic bay encompassing 1.55 million square kilometers and has been designated as a protected zone from commercial fishing and mineral exploitation. This international agreement is scheduled to take effect in December of 2017. Wildlife in Decline: Earth's Vertebrates Fall 58% In Past Four Decades Worldwide populations of fish, amphibians, mammals, and birds have plunged by 58% percent since 1970 as human activities overwhelm the environment, according to a World Wildlife Fund conservation group. The index is predicted to continue falling to 67 percent by 2020 if current trends hold. Bacteria Can't Get a Grip on Self-healing Slippery Surface In a report published in the journal Biomaterials, a team of scientists at Beth Israel Deaconess Medical Center, the Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences at Harvard University have demonstrated that an innovative, ultra-low adhesive coating prevented bacteria from attaching to surfaces treated with it, reducing bacterial adhesion by more than 98 percent in laboratory tests.

It's so much fun talking about the latest science that even the expanded version seems to end way too soon. How can one not like it? We talked about newly discovered antibiotic properties of Tasmanian Devil milk, and wondered aloud about who is the unfortunate person tasked with milking the little devils. A new technique has been developed in Japan to coax mouse stem cells, both embryonic and induced pluripotent, all the way through to oogenesis!

Walruses make some of the most varied sounds of any mammal. Some of the sounds are downright rude! <hr /> <h3>Blue Streak Science News Roundup</h3> These are summaries of our discussions on the podcast. For the full conversation please listen to this episode of the Blue Streak Science Podcast. Reconstitution in vitro of the entire cycle of the mouse female germ line For the first time ever, scientists have reprogrammed mouse embryonic stem cells and induced pluripotent stem cells to become fully functional oocytes. This paper was published in the 17 October issue of the journal Nature and describes this technique, the process of oogenesis, and may open an avenue for a similar technique using human embryonic stem cells and induced pluripotent stem cells. Tasmanian devil milk fights superbugs From BBC Health. According to a Sydney University research team, Tasmanian devil milk apparently contains important peptides that appear to be able to kill hard-to-treat infections, including MRSA. It’s believed the devils evolved this cocktail to help their young grow stronger. In this post-antibiotic era the scientists are looking to make new treatments that mimic the peptides. They’ve scanned the devils' genetic code to find and recreate the infection-fighting compounds, called cathelicidins. West Antarctica glacier unstable From the Washington Post. There was an article that talks about a moment in history, 2014, when when two separate research papers said there was reason to think a frozen sector of West Antarctica, called the Amundsen Sea region, may have been destabilized. Hurricane Matthew exposes civil war cannonballs From LiveScience.com. A day after Hurricane Matthew lashed the South Carolina coast with tidal surge, torrential rain, and high winds a resident walking along the east end of Folly Island found a pile of 16 corroded cannonballs resting on the sand. ExoMars Schiaparelli lander likely lost Regarding the ExoMars mission landing vehicle, named Schiaparelli. Well, we have some good news and some bad news. <div class="mceTemp"> <dl id="attachment_2215" class="wp-caption alignright" style= "width: 360px;"> <dt class="wp-caption-dt"><img class="size-medium wp-image-2215" src= "http://www.bluestreakscience.com/wp-content/uploads/2016/10/schiaparelliexomars-350x308.jpg" alt="Creative Commons - Wikimedia" width="350" height="308" /></dt> <dd class="wp-caption-dd">ExoMars Schiaparelli Lander</dd> </dl> </div> First the good news, it hit near the target zone! The bad news, it hit the target zone like it was shot out of a cannon! There is actually some good news for real. From Scientific American, The ExoMars 2016 mission is in business despite the apparent failure of its lander to touch down softly on the Red Planet. The lander seems to have deployed its parachute too early and fired its thrusters for an insufficient amount of time as it streaked through the Martian atmosphere like a bat out of hell. But in spite of the loss of the lander the the Trace Gas Orbiter is gearing up for spectacular science at Mars. Monkeys making stone knives Another one from Scientific American, monkeys with knives! Picture this. A monkey picks up a potato-sized rock in his little hands, raises it above his head and smashes it down with all his might on another stone embedded in the ground. As the monkey bashes away flakes fly off the rock he is wielding. They’re sharp enough to cut meat or plant material. The monkey does not pay much attention to the flakes, save to place one on the embedded rock and attempt to smash it, too. But he has unintentionally produced artifacts that look for all the world like stone tools found at some human archaeological sites. Now a new study has examined the capuchin monkey-produced stone flakes and compared them to human-made artifacts, and it turns out that the chips meet criteria used to distinguish human tools from naturally broken rocks. <hr /> <h3>Name That Phobia!</h3> Today we introduced another new game to the podcast.

This procedure is the best and latest technology, and so the military are trialling it first in order to do the best for their service men and women. However, it's not available on the NHS. OI is a modern procedure that would implant James’ bones with titanium implants which would allow him to bolt on an artificial limb in seconds, with potentially zero discomfort once healed. This could provide him with the ability to bear weight directly through his skeleton and allow accurate control and placement of his foot by being linked firmly to his bones instead of clinging on his skin. This is where you can help. James is not a member of the military, so he must raise the funds himself to get a shot at getting this surgery. James has set of goal of £95,000 through a <a href= "https://www.gofundme.com/titaniumjames?utm_source=internal&utm_medium=email&utm_content=cta_button&utm_campaign=upd_n" target="_blank">GoFundMe</a> campaign. The Blue Streak Science online community has always been there for us, and we love you for it. We now ask that you share your generosity and contribute whatever you can to help James toward his goal of having near normal mobility and less pain.

043: Trillions of galaxies, a virus that steals spider venom genes, ancient human footprints and so much more!
<div class="mceTemp"> <dl id="attachment_2188" class="wp-caption alignright" style= "width: 360px;"> <dt class="wp-caption-dt"><img class="size-medium wp-image-2188" src= "http://www.bluestreakscience.com/wp-content/uploads/2016/10/Black_widow_spider_reduced-350x235.jpg" alt="Black Widow Spider - Latrodectus mactans" width="350" height= "235" /></dt> <dd class="wp-caption-dd">Black Widow Spider - Latrodectus mactans</dd> </dl> </div> It was one of those weeks in science; an embarrassment of riches. And talk about abundance, our universe may contain upwards of 2 trillion galaxies! You know, a trillion here, a trillion there and soon we're talking big numbers here. Okay, follow along with me. A virus that incorporates a gene from a spider. First, that's cool because it's a virus using the DNA of a complex organism. The gene happens to be a gene that codes for black widow venom. That's right. Black widow venom. Now this virus, a bacteriophage, uses that gene to poke holes in bacteria. Whoah! Then we talk about 5,000 to 19,000 year old human footprints, lots of 'em, in volcanic sediment. These footprints tell numerous stories about ancestors and it is just so fascinating. It's so easy to visualize them and imagine who they were, and what they were doing. <hr /> <h3>What The Hell Was That?</h3> We reveal the answer to last week's terrifying and disturbing sound. No, no listener or host got the correct answer, but some were close. This week's sound is a good one. Sounds somewhat like me snoring while suffering from a bad cold, after eating lots of cabbage. Lovely. <hr /> <h3>Blue Streak Science News Roundup</h3> These are summaries of our discussions on the podcast. For the full conversation please listen to this episode of the Blue Streak Science Podcast. There are 10 times more galaxies in our universe than we'd estimated <div class="mceTemp"> <dl id="attachment_2190" class="wp-caption alignright" style= "width: 360px;"> <dt class="wp-caption-dt"><img class="size-medium wp-image-2190" src= "http://www.bluestreakscience.com/wp-content/uploads/2016/10/galaxy-350x350.jpg" alt="Pretty galaxy. Seems there's loads of 'em. " width="350" height="350" /></dt> <dd class="wp-caption-dd">Pretty galaxy. Seems there's loads of 'em.</dd> </dl> </div> Astronomers led by Christopher Conselice at the University of Nottingham converted “pencil beam” images of deep space into 3-dimensional maps, allowing them to calculate the density of galaxies in that volume. Using mathematical models to infer yet to be observed galaxies they concluded that the universe contains at least 2 trillion galaxies They combined data from many ground- and space-based telescopes to look at how the number of galaxies in a typical volume of the universe has changed over much of cosmic history. Virus steals black widow poison gene to help it attack A type of virus that only infects bacteria, a bacteriophage, has apparently nicked the DNA of black widow spiders to attack bacteria. This virus is actually using the genes that code for the spider’s venom! It is the first time we’ve seen a virus take genes from such a complex organism. Treasure Trove of Ancient Human Footprints Found Near Volcano A massive set of more than 400 human footprints found by geologists is thought to date back to between 10,000 and 19,000 years ago. It was previously thought that the footprints dated back as far as 120,000 years, and that they had been preserved by ash falling from the sky, following the eruption of a nearby volcano. But the research team has now been able to date them more accurately after discovering that a muddy flow of debris and ash from the volcano's sides was responsible. <hr /> <h3>Says Who?!</h3> Sophie answers correctly! The choices were Carl Sagan, Leonard Nimoy, Ray Bradbury, and Isaac Asimov. Oh, you haven't heard the quote? Well, you're just going to have to listen to the podcast for that! I'm a mean s.o.b., ain't I? <hr /> <h3>Shout-outs and Acknowledgments</h3> <h4>The <a href="http://www.bluestreakscience.com/cafe">Science Cafe'</a></h4> Blue Streak Science has a new show!

042: Hurricane Matthew, more water worlds, mind-reading apes and "Says Who?"
It has been a tumultuous week in American politics! Wow! But Blue Streak Science stays above the fray as we deliver the latest science to the world in our own special way. We talked about birds in hurricanes and bat-shit crazy conspiracy theorists. Did you hear the one about the chimp who could read minds? We talked about new research that shows our close cousins to possess similar "theory of mind" as humans, including the ability to anticipate when someone is about to do the wrong thing. It involved a guy in a King Kong suit. You can't make this stuff up! We also talked about Saturn's moon Dione and how it has an ocean. How many moons are there now with oceans? I lost count. "If everybody had an ocean/Across the U. S. A./Then everybody'd be surfin'/Like Californi-a" Put on your baggies and wax your board 'cause surf's up in the solar system! What The Hell Was That? Nobody got last week's sound because it was freakin' difficult. No, you'll never get. But you can try! Just have a listen. All the hosts were very creeped-out by this week's sound. You're welcome for the nightmares it may cause. Blue Streak Science News Roundup These are summaries of our discussions on the podcast. For the full conversation please listen to this episode of the Blue Streak Science Podcast. Hurricane Matthew The remnants of the storm still causing havoc and destruction in the U.S. state of North Carolina. As bad as that is Hurricane Matthew has also caused huge amounts of property damage in Florida. But the greatest tragedy is in Haiti where the death toll has already surpassed 1000 while disease and starvation in its aftermath threaten many more. However, a hurricane’s effects aren’t limited to people. Radar observations of Hurricane Matthew showed that birds were traveling inside of the eye the storm. There was also an article in the Huffington Post that talked about some conspiracy theories regarding hurricanes put forth extreme right commentators Matt Drudge and Rush Limbaugh. Drudge suggested the government has a “monopoly on data” and is fudging its forecasts to make an “exaggerated point on climate.” Saturn's moon Dione may harbor an underground ocean So say researchers reporting online on 28 September in Geophysical Research Letters. This club of watery worlds in our solar system include Saturn's moon Enceladus, several moons of Jupiter and the dwarf planet Pluto as we reported last week. Dione’s ocean is about 100 kilometers below the surface and is about 65 kilometers deep. The researchers used measurements of Dione’s gravity made by the venerable Cassini spacecraft. Can great apes read minds? This study published in “Science” on 6 October. Over the decades we’ve learned that non-human apes possess many aspect of the “theory of mind”. We are able to think about others’ thoughts and emotions (except orange-haired apes, such as an American Presidential candidate). We form ideas about what beliefs and feelings are held in the minds of others – and recognize that they can be different from our own.But this common trait seems to drop off when it comes to non-human ape’s understanding that someone else’s belief may be false, and that’s what this new research looks at. New game! It's called "Says Who?" Congratulations to host Tom Di Liberto for giving the correct answer on the inaugural "Says Who?" game! Well done.

The article states that the couple have made big headlines with their “Chan Zuckerberg Initiative”, and it seems to take issue with its goal of spending the aforementioned sum over the next 10 years "to cure, prevent, or manage all disease within our children’s lifetime".

This research looked at Sputnik Planum, a 900 kilometer wide basin. At least part of this basin looks like it was formed by an impact. The researchers examined the impact area and also looked at the dynamics between Pluto and its moon Charon. They concluded that the rebound from this impact area rebounded and brought up denser material from below. It appears that water, which is denser than ice, welled up from below to even out the impact zone. The researchers modeled different scenarios that would best explain Sputnik Planum’s observed size depth, while also producing a the type of crater observed. The best scenario is one of an ocean layer more than 100 kilometers thick, with a salinity of around 30 percent. <hr /> <h3>False Positive, the science game with the scary name!</h3> Every week I tell our blue streak science team 4 science news items or facts.

039: Introducing "Science Roundup"!
<h3>Opening Word</h3> We're back! After an extended hiatus the Blue Streak Science Podcast has returned. We still have listener favorites the What The Hell Was That game and False Positive. But we've shelved the Blue Streak Science News and are hitching up the News Roundup! Sure, we're a little rusty, but we're itching (chafing?) to get back on the saddle and on down the trail. Yee-haw! <hr /> <h3>What The Hell Was That?</h3> Today's science sound is a tough one. Do you think you have what it takes to identify it? Give it a try. Have a listen! <hr /> <h3>Blue Streak Science News Roundup</h3> <img class= "alignright size-medium wp-image-2129" src= "http://bluestreaksci.staging.wpengine.com/wp-content/uploads/2016/09/39_hacker-350x233.jpg" alt="ha" width="350" height="233" /> Eureka! I have found it! Or, Eurekalert! Where the hell is it? The news release service known as Eurekalert, was subject to "an aggressive attack" by hackers beginning on 9 september. This site is administered by the American Association for the Advancement of Science, or AAAS, the publishers of the top-tier journal “Science”. The hack wasn’t discovered until 11 September and by then the damage had been done. User id’s and passwords were compromised. As a result of the hack, Eurekalert was taken offline on 11 September. On 18 September in an offline notice Eurekalert said, “significant progress has been made toward a full recovery. The entire Eurekalert system environment has now been rebuilt, and we have subjected it to multiple rounds of cyber-security testing to ensure that it meets the highest standards of security.” As of Monday, 19 September the site was still down. Scientists Watch as Bacteria Evolve Antibiotic Resistance From Science News on 8 September, scientists watch as bacteria evolve antibiotic resistance. A giant petri dish coated with variable concentrations of antibiotics is allowing scientists to view e. Coli as they adjust to ever higher levels of antibiotics, reports microbiologist Michael Baym in the 9 September issue of Science. The freakishly large petri dish was more than a meter long instead of a standard palm-sized dish. The researchers created a gradient of antibiotics on the plate with low concentrations at the edges, and increasing as you go toward the middle of the plate. They then put the e. Coli at each end of the plate, sat back, placed wagers and watched the race unfold before their eyes...over the next week and a half. Arctic Summer Sea Ice Melts to Second Lower Level Every Recorded From New Scientist on 16 September we learn that, coming out of the planet’s hottest August in recorded history, Arctic sea ice has melted to the second lowest level on record. This, despite a relatively cool summer up there – and the loss of ice may already be having ecological consequences. Measurements taken by the Snow and Ice Data Center in the U.S. found that levels of Arctic sea ice tied 2007 for the second lowest on record. Again, this was with a relatively cool summer in the arctic. With more typical warmer conditions, the Arctic could see very dramatic losses of ice in the coming years, the scientists warned. <hr /> <h3>False Positive, the science game with the scary name!</h3> Ivy scores a whale of a victory!

038: Science and the Brexit. The UK votes and JD gives his scientifically biased opinion on the matter
<h3><img class="alignright wp-image-2115 size-medium" src= "http://www.bluestreakscience.com/wp-content/uploads/2015/01/brexit-350x247.jpg" alt="brexit" width="350" height="247" /></h3> This week the people of the United Kingdom will be making an enormously important choice. The result of the "Brexit" vote will profoundly affect the lives of Britons for decades. To leave or not to leave? That is the question. Last week in the closing I mentioned that “science is a team sport”. Some of the most valuable and productive collaborations are the ones that cross borders. The UK now produce 62% of its scientific output as international collaborations, and that proportion is growing rapidly. The EU has facilitated those collaborations for decades making the European Union the science powerhouse of the world. No, it’s not the United States. The EU has 34% more scientific output than the United States, and they’re increasing that lead year after year. So let’s be clear, if the UK vote to leave there will be consequences. The UK will lose its currently prominent, even dominant role on forming science policy in the EU. Scientific discovery drives industry and health care. If the UK leaves then they’ll not only lose their influence in shaping European Union science, but both academia and industry will be big losers. The vast majority of scientists in the United Kingdom are dead-set against leaving the European Union. So when you go to the polls this week, think about that. And by all means, go to the polls this week. <hr /> <h3>What The Hell Was That?</h3> Kevin O'Sullivan, a listener from Ithaca, New York, was the first to answer correctly last week's mystery sound.

We have a wonderful time doing this, but I cannot help but think of the many funerals, the suffering, and the plight of the survivors. For purely political reasons the Centers for Disease Control are forbidden from doing epidemiological research on gun violence in the United States. Science is a powerful weapon and those who favor unfettered trade in weapons of war have fought to keep one weapon, science, away from us all. No amount of prayer, moments of silence, or hand wringing will bring back the dead or prevent future victims from being cut down. The only thing that can reduce the carnage is brave action. Will they forgive us if we do nothing? <hr /> <h3>What The Hell Was That?</h3> Camille Corra, a listener from Santiago, Chile, was the first to answer correctly last week's mystery sound.

Those critically important role models that inspire children to believe in themselves, that they can be scientists and engineers, too. They do this by providing free science, technology, engineering and math programs in a fun, nurturing and interactive environment. This is the kind of locally based organization that can often have the greatest and longest lasting positive effect on a child’s life. Science club for girls also has teen leadership programs to give girls the chance to be role models and to teach the younger children, to develop the kind of valuable skills they’ll need when they go on to college and beyond. I encourage everyone listening to check out science club for girls. It’ll just make you feel go to know that such programs exist. More importantly, if you like what they’re doing then please send them a donation. These programs are free for the children, but science club for girls depends on the generosity of people like you who understand the value of a science education. And if you have kids and you live in eastern Massachusetts then by all means contact them! <hr /> This episode of Blue Streak Science Podcast comes to you from Sydney, Australia; Santa Rosa, California; and Cambridge, England.

Bad-ass bacteria arrives in U.S., forests making their own rain, and so much more!
<h3>Blue Streak Science News</h3> <h4><a href= "http://www.nature.com/news/cloud-seeding-surprise-could-improve-climate-predictions-1.19971"> Cloud-seeding surprise could improve climate predictions</a></h4> The cooling effect of pollution may have been exaggerated. Fossil fuel burning spews sulfuric acid into the air, where it can form airborne particles that seed clouds and cool Earth’s climate. But that’s not the only way these airborne particles can form, three new studies suggest. Tree vapors can turn into cooling airborne particles, too. The discovery means these particles were more abundant before the Industrial Revolution than previously thought. Climate scientists have therefore overestimated cooling caused by air pollution, says atmospheric chemist Urs Baltensperger, who coauthored the three studies. Simulating unpolluted air in a cloud chamber, Baltensperger and colleagues created microscopic particles from vapors released by trees. In the real world, cosmic rays whizzing into the atmosphere foster the development of these particles, the researchers propose in the May 26 Nature. Once formed, the particles can grow large enough to form the heart of cloud droplets, the researchers show in a second paper in Nature. After sniffing the air over the Swiss Alps, some of the same researchers report in the May 27Science the discovery of the particles in the wild. “These particles don’t just form in the laboratory, but also by Mother Nature,” says Baltensperger, of the Paul Scherrer Institute in Villigen, Switzerland. Airborne particles, called aerosols, are microscopic bundles of molecules. Some aerosols start fully formed, such as dust and salts from sea spray, while others assemble from molecules in the atmosphere. Since the 1970s, scientists have suspected that sulfuric acid is a mandatory ingredient for aerosols assembled in the air. Sulfuric acid molecules react with other molecules to form clusters that, if they grow large enough, can become stable. Human activities such as coal burning have boosted sulfuric acid concentrations in the atmosphere, subsequently boosting the abundance of aerosols that seed clouds and reflect sunlight like miniature disco balls. That aerosol boost partially offsets warming from greenhouse gases. A cloud chamber at the CERN laboratory near Geneva allowed Baltensperger and his collaborators to simulate the atmosphere when sulfuric acid was scarce. The researchers added alpha-pinene, the organic vapor that gives pine trees their characteristic smell, to pristine air and watched for growing aerosols. Previous, though inconclusive, work suggested that the pine vapors might form aerosols. Alpha-pinene molecules reacted with ozone in the air and formed molecules that reacted and bundled together to form aerosols, the researchers observed. The researchers added an extra layer of realism by using one of CERN’s particle beams to mimic ions from the cosmic rays bombarding Earth’s atmosphere. The “rays” led to the formation of as many as 100 times the number of aerosols. The added ions help stabilize the growing aerosols, the researchers propose. Further testing showed that the newborn aerosols can rapidly grow from around 2 nanometers wide — roughly the diameter of a DNA helix — to 80 nanometers across, large enough to seed cloud droplets. At a research station high in the Swiss Alps, researchers observed aerosol formation during atmospheric conditions with low sulfuric acid concentrations and abundant molecules akin to alpha-pinene. The researchers couldn’t confirm the rapid growth seen in the lab, though. Quantifying the overall climate influence of fossil fuel burning in light of the new discovery will be tricky, says Renyi Zhang, an atmospheric chemist at Texas A&M University in College Station. “Atmospheric processes are complex,” he says. “They had a pure setup, but in reality the atmosphere is loaded with chemicals. It’s hard to draw direct conclusions at this point.” <h4><a href= "https://www.sciencenews.org/article/bacteria-resistant-last-resort-antibiotic-appears-us"> Bacteria resistant to last-resort antibiotic appears in U.S.</a></h4> For the first time, a US patient has been infected with bacteria resistant to an antibiotic used as a last resort, scientists said Thursday. The patient, a 49-year-old woman in Pennsylvania, has recovered but health officials fear that if the resistance spreads to other bacteria, the country may soon see supergerms impervious to all known antibiotics. “It is the end of the road for antibiotics unless we act urgently,” Dr Tom Frieden, director of the Centers for Disease Control and Prevention (CDC), said in Washington. <img class="alignright wp-image-1648 size-medium" src= "http://www.bluestreakscience.com/wp-content/uploads/2015/11/bacteria-350x350.jpg" alt="A color enhanced photo of cocci type bacteria. " width="350" height="350" /> Other countries have already seen multidrug-resistant superbugs that no antibiotic can fight. So far, the US has not. But this sets the stage for that development, CDC officials said. The woman had gone to a military clinic in Pennsylvania in April and was treated for a urinary tract infection. Initial tests found she was infected with E coli bacteria, a common variety of germ seen in the gut that often makes its way to the bladder. But the tests showed this E coli was resistant to antibiotics commonly used first for such infections. She was successfully treated with another kind of antibiotic. But while she has recovered, further testing completed in the last week confirmed the E coli was carrying a gene for resistance against the drug colistin. Colistin is an old antibiotic. By the 1970s, doctors had mostly stopped using it because of its harsh side effects. But it was brought back as other antibiotics began losing their effectiveness. It is used against hard-to-treat bacteria that resist one of the last lines of defence, antibiotics called carbapenems. If those germs pick up the colistin-resistance gene, doctors may be out of treatment options, health officials say. “This is another piece of a really nasty puzzle that we didn’t want to see here,” said Dr Beth Bell, who oversees CDC’s emerging infectious diseases programs. The CDC is working with Pennsylvania health officials to interview the woman and her family to try to figure out how she might have picked up the strain. The woman had not travelled outside the country recently, officials said. The colistin-resistant gene has been seen in animals and people in China, Europe and Canada. Federal officials said on Thursday that colistin-resistant E coli has also been found in a pig in the US, but there was nothing to link the finding to the Pennsylvania case. Researchers at Walter Reed national military medical center, who did the confirmatory tests, reported on the Pennsylvania case on Thursday in a journal of the American Society of Microbiology. <h4><a href= "https://cosmosmagazine.com/space/rosetta-finds-ingredients-life-comet-67ps-halo"> Rosetta finds ingredients for life in Comet 67P's halo</a> </h4> The theory of panspermia posits that life on Earth may have been seeded by meteorites and comets carrying hardy spores of microorganisms. This possibility is what makes studying comets such an exciting area of research for scientists seeking to understand the origin of life on our planet and the evolution of the solar system. Now, a new study, based on data gathered by instruments on board the European Space Agency’s (ESA) Rosetta spacecraft — which is currently following the comet 67P/Churyumov-Gerasimenko — further bolsters the possibility that the building blocks of life on Earth may have come from outer space. Researchers have detected the amino acid glycine, commonly found in proteins, and phosphorus, a key component of DNA and cell membranes, in the coma of the comet. “This is the first unambiguous detection of glycine at a comet,” lead author Kathrin Altwegg, principal investigator of the ROSINA instrument that made the measurements, said in a statement. “At the same time, we also detected certain other organic molecules that can be precursors to glycine, hinting at the possible ways in which it may have formed.” A coma is the fuzzy, nebulous envelope of dust and gas that usually surrounds a comet’s nucleus. The shape and size of the coma vary depending on the comet’s composition and its distance from the sun. According to the study, “the presence of glycine, phosphorus, and a multitude of organic molecules, including hydrogen sulfide and hydrogen cyanide ... supports the idea that comets delivered key molecules for prebiotic chemistry throughout the solar system and, in particular, to the early Earth, drastically increasing the concentration of life-related chemicals by impact on a closed water body.” Scientists believe that life on Earth originated nearly 3.7 billion years ago, bubbling out of a “primordial soup” rich in organic compounds. While we now have a clear picture of the evolution of life from its most ancient single-celled form to the present-day complexity we see around us, what is less clear is how the seeds of life came to exist on Earth. “There is still a lot of uncertainty regarding the chemistry on early Earth and there is of course a huge evolutionary gap to fill between the delivery of these ingredients via cometary impacts and life taking hold,” co-author Hervé Cottin said in the statement. “But the important point is that comets have not really changed in 4.5 billion years — they grant us direct access to some of the ingredients that likely ended up in the prebiotic soup that eventually resulted in the origin of life on Earth.” With the discovery of glycine — the simplest of all amino acids — and phosphorus, the theory of panspermia has been lent further credence. “Demonstrating that comets are reservoirs of primitive material in the Solar System and vessels that could have transported these vital ingredients to Earth, is one of the key goals of the Rosetta mission, and we are delighted with this result,” Matt Taylor, ESA's Rosetta project scientist, said in the statement. <h4><a href= "https://www.theguardian.com/science/2016/may/31/stephen-hawking-donald-trump-popularity-inexplicable-and-brexit-spells-disaster"> Trump's popularity inexplicable and Brexit spells disaster, says Stephen Hawking</a></h4> <div class="mceTemp"> <dl id="attachment_1970" class="wp-caption alignright" style= "width: 360px;"> <dt class="wp-caption-dt"><img class="wp-image-1970 size-medium" src= "http://www.bluestreakscience.com/wp-content/uploads/2016/06/trump-350x233.jpg" alt="trump" width="350" height="233" /></dt> <dd class="wp-caption-dd">Donald Trump. Small hands. Huuuge ego.</dd> </dl> </div> Stephen Hawking has said that he fails to understand the popularity of Donald Trump, the presumptive US Republican presidential candidate. ITV’s Good Morning Britain asked the man who has widened the world’s understanding of time, space, stars, galaxies and black holes if he could explain the popular appeal of the billionaire tycoon. Hawking, perhaps the world’s most famous living scientist and the author of one of the world’s best-selling books, replied: “I can’t. He’s a demagogue who seems to appeal to the lowest common denominator.” He also ventured once again into political issues, appealing to British voters to back the remain campaign in the EU referendum on 23 June – not just for economic and security reasons, but for the sake of science as well. In March, he pronounced the prospect of Brexit “a disaster” for science. “Gone are the days when we could stand on our own, against the world,” he said on the television breakfast show. “We need to be part of a larger group of nations, both for our security and our trade. The possibility of our leaving the EU has already led to a sharp fall in the pound, because the markets judge that it will damage our economy.” Hawking also addressed the biggest concern of many: immigration. “There are two obvious reasons why we should stay in. The first is that it promotes the mobility of people. Students can come here from EU countries to study, and our students can go to other EU universities. More importantly, at the level of research, the exchange of people enables skills to transfer more quickly, and brings new people with different ideas, derived from their different backgrounds,” he said. “The other reason is financial. The European Research Council has given large grants to UK institutions, either to foster or promote exchanges.” The Cambridge scientist, like Isaac Newton 350 years ago, was once Lucasian professor of mathematics at Cambridge University. Hawking was diagnosed with motor neurone disease in 1963 and given two years to live. Instead he wrote A Brief History of Time and became one of the world’s bestselling authors, and one of the world’s most instantly recognised scientists: he has appeared in his wheelchair in both Star Trek and the Simpsons. Because he communicates fairly slowly, using a computerised voice that pronounces words he must spell out using assistive technology, all his opinions must be counted as carefully considered. And over the years, he has been unapologetically opinionated, not just on behalf of his fellow scientists, and on behalf of Britain’s disabled, but on wider matters: he joined an academic boycott in protest against Israeli treatment of Palestinians; he backed a recent $100m project to accelerate a tiny spacecraft to a fifth of the speed of light and send it to the nearest star system; he has spoken in favour of assisted suicide for the terminally ill; he has spoken up for atheism; he has made ominous pronouncements about artificial intelligence research; and he has even invited the fans of One Direction to imagine an alternative universe in which Zayn Malik was still with the band. His latest return to referendum politics is less of a surprise: many of Britain’s most senior scientists have backed the remain campaign. The exit enthusiasts however, are not swayed. “The EU has been bad for science – increasing costs and bureaucracy. The clinical trials directive, for example, acted to double the cost of cancer research – as leading scientists and medical practitioners have acknowledged,” said the Vote Leave chief executive, Matthew Elliott. “In the internet age, it is patently ridiculous to suggest that the referendum will have an impact on the exchange of information between scientists. And with our world class universities, the calibre of scientists wanting to study here is unlikely to do anything except grow. “We give more money to the EU than we get back – meaning we could spend more on science if we vote to leave.” This episode of the Blue Streak Science Podcast comes to you from Sydney, Australia; and Santa Rosa, California.

Remember him? He’s the asshole who bumped up the price of a 62 year old drug against toxoplasmosis from $13.50 per pill to $750. He once again has plans to sharply increase the price of a decades-old drug for a serious infectious disease. This time it’s a drug that treats Chagas disease, a parasitic infection that can cause potentially lethal heart problems. The plan also is upsetting some organizations that supply drugs for neglected diseases because Shkreli has said he wants to take advantage of a federal program intended to encourage companies to develop such drugs. The program awards vouchers that can be sold to other companies for hundreds of millions of dollars. This story comes from the New York Times. Shkreli has said he hopes to obtain such a voucher by getting the Chagas disease drug approved by the Food and Drug Administration for sale in the United States. Critics say that it would be another case of the system being abused by awarding a voucher not for developing a new drug but merely for obtaining F.D.A. approval of a drug already used in tropical countries. Mr. Shkreli declined to comment. Last month, Shkreli led an investor group that took control of a failing California biotechnology company, buying a majority of its shares on the open market at an average price of about $1.50 a share. As one of his first moves at KaloBios, Shkreli agreed to license the worldwide rights to one version of benznidazole, a standard treatment for Chagas Disease in South and Central America. Benznidazole has never been approved for sale in the United States but is provided free to patients by the CDC on an experimental basis. Shkreli said on a conference call with KaloBios investors last week that if the company won F.D.A. approval for benznidazole, it would have exclusive rights to sell it in the United States for at least five years. He said the price would be similar to that of hepatitis C drugs, which cost $60,000 to nearly $100,000 for a course of treatment. In Latin America, benznidazole costs $50 to $100 for the typical two-month course of treatment. It is estimated that 300,000 people in the United States have Chagas disease, virtually all of them immigrants from Latin America who were infected before they came. Chagas is caused by a parasite, Trypanosoma cruzi, that is in the feces of an insect called the kissing bug, because it often bites people on the face and lips. However, few of the cases in the United States are acute cases, and the actual demand for the drug would be very small. So it seems that the voucher itself could be the real prize. “The only reason for him to do this is to get the voucher and turn around and sell it,” said Dr. Caryn Bern, a Chagas disease specialist at the University of California, San Francisco. Critics say that the award of a voucher for F.D.A. approval of a drug already used in tropical countries is more a get-rich-quick scheme than a benefit to people with neglected diseases. Martin Shkreli, for your plans to raise the price of benznidazole from $100 per course to over $60,000 per course AND for your intention of stealing money from the taxpayers of the United States, you are the Blue Streak Science A$$**** of the Week!

Coke’s chief science and health officer, Dr. Rhonda Applebaum, created a group called the Global Energy Balance Network. This group consisted of university scientists, and they encouraged the public to focus on exercise and not so much about how what we eat and drink contributes to the epidemic of obesity. Coca-Cola spent $1.5 million last year to support the group, which included a $1 million grant to the University of Colorado medical school, where the nonprofit group’s president, James O. Hill, a prominent obesity researcher, is a professor. Coke’s financial ties to the group were first reported in an article in The New York Times in August, which prompted criticism that the soft drink giant was trying to exert undue influence scientific research on sugary drinks. This story appeared in the New York Times on 24 November, 2015. The university returned the money to Coca-Cola this month after public health experts raised concerns. Dr. Applebaum, who is a food scientist with a Ph.D. in microbiology, had been Coke’s chief scientific and regulatory officer since 2004. In that role she helped spearhead the company’s efforts to work with scientists as a way to counter criticism about sugary drinks. At a food industry conference in 2012, Dr. Applebaum gave a talk about Coca-Cola’s strategy of “cultivating relationships” with top scientists as a way to “balance the debate” about soft drinks. “Balance the debate”? I call that doing what you can to create the impression of false equivalency...something we often see with climate science deniers, too. Coca-Cola has said that while it offered financial support for the Global Energy Balance Network, the company had no influence on the group or the scientific research it produced. But reports show that Dr. Applebaum and other executives at Coke helped pick the group’s leaders, create its mission statement and design its website, findings first reported this week by The Associated Press. The AP also published a series of emails between Dr. Hill and Coke executives that revealed the initial strategy of the Global Energy Balance Network. Dr. Hill proposed publishing research that would help the company fend off criticism about its products by shifting the blame for obesity to physical inactivity. Dr. Hill told executives at Coca-Cola that he wanted to work on the company’s behalf to improve its public reputation. He also wrote to executives at the company that it was “not fair” that Coca-Cola was being singled out as “the No. 1 villain in the obesity world.” He added: “I want to help your company avoid the image of being a problem in people’s lives and back to being a company that brings important and fun things to them.” In an interview in August, Dr. Hill insisted that Coca-Cola did not speak for him or his organization. “They’re not running the show,” he said. “We’re running the show.” In a statement on Tuesday, the University of Colorado School of Medicine suggested it did not see any problems with Dr. Hill’s relationship with Coca-Cola. “The school of medicine does not prohibit faculty members from communicating with governmental, for-profit or nonprofit entities that provide funding for initiatives intended to improve individual and public health. The school does expect such efforts to be hypothesis-driven and designed to answer questions and not to advance a specific point of view.” Michael F. Jacobson, the executive director of the Center for Science in the Public Interest, a consumer advocacy group, said it was concerning to see “how a major corporation is using a professor to propagate their views.” It is tempting to give this week’s award to several people in this rogue’s gallery. However, I’m sticking with just one, and it is Dr. James Hill of the University of Colorado. You are Blue Streak Science A$$#*\& of the Week!

<h3>Blue Streak Science News</h3> <ul> <li>Birth Control for men?</li> <li>Tapeworm spreads cancer to human</li> <li>Sonic screwdriver opens the brain</li> <li>Secretive speartooth sharks snagged for science... <ul> <li>whilst selling seashells by the seashore</li> </ul> </li> <li>Solar wind stripping Martian atmosphere</li> <li>WHO officially declares Sierra Leone Ebola-free</li> <li>Wine tasting is junk science</li> </ul> <h3>A$$#*(& of the Week</h3> Last week I was scrolling through my Facebook newsfeed. Tucked in among the cat videos and “here’s what I’m having for dinner” pictures was a piece from the Daily Express written by James Delingpole. James Delingpole is an English columnist who has written for the Daily Mail, the aforementioned Daily Express, The Times, The Daily Telegraph, and The Spectator. He’s also the executive editor for the London branch of the Breitbart News Network, a radical right wing news blog founded by the late Andrew Breitbart. It seems like every week on the A$$#8(& of the Week I’m talking about some anti-science blowhard who denies that anthropogenic climate change is real. This is becoming not unlike trying to convince people that the earth is a sphere and not as flat as a pizza. Last week a new NASA study came out that shows there’s been a net increase in land ice in Antarctica in recent years, despite a decline in some parts of the continent. The study's lead author predicted that climate science deniers would distort this study for their own agenda. Although the conclusions from this study do nothing to contradict the worldwide scientific consensus on climate change this didn’t stop James Delingpole from doing just that. In this piece, titled MELTDOWN MYTH: Antarctic ice growing is just the first EVIDENCE global warming is NOT REAL, Delingpole even brings up the instance in 2013 where an Australian research ship was trapped in sea ice. He ignores that this phenomenon of increased sea ice was predicted to occur because of the measurably less saline seas in that region...less saline because of the increased level of meltwater from that part of the Antarctic continent. As most of you know, saltwater has a lower freezing temperature than fresh. Result, increased sea ice for a while. But don’t let the science get in the way, James Delingpole. He once wrote, "I am not a scientist and have never claimed to be," and that he does not have a science degree. That’s not necessarily a bad thing. If you read the scientific literature and just follow the evidence, wherever it leads, and look at the entirely of it, then fine. However, In a BBC Horizon documentary called "Science under Attack", Delingpole responded to a question as to whether he had read any peer-reviewed papers. He replied that as a journalist "it is not my job" to read peer-reviewed papers, but rather to be "an interpreter of interpretations". That is exactly what he did with this article. He interpreted interpretations and ignored the peer-reviewed science...again. For this unresearched hit piece, James Delingpole, you are the Blue Streak Science A$$#*(& of the Week. <h3> </h3>

Who is Pam Bondi? Pam Bondi was appointed to her office by Governor Rick Scott, who is infamous for when he said "I'm not a scientist" in response to questions about climate change prior to his re-election. In the bizarro world of Governor Rick Scott no state employee is permitted to address or say things like “climate change” or “global warming”. Pam Bondi, being the loyal foot soldier in the Rick Scott administration, is doing her part in their war against science and the environment. In 2014 she legally challenged a Chesapeake Bay water cleanup plan that most of the states around the bay had agreed to but industry and agriculture groups opposed. She also is challenging federal wetlands rules that agricultural groups and stormwater utilities are opposing. Incidentally, she was the lead state attorney general among 26 in an unsuccessful lawsuit seeking to overturn the Affordable Care Act. She has also fought tooth-and-nail against equal marriage. What has Pam Bondi done this time? She's now joined a challenge to President Obama's Clean Power Plan What’s the Clean Power Plan? It’s a set of rules implemented by the Environmental Protection Agency that will reduce carbon emissions from power plants for the first time. Previously, power plants were allowed to dump unlimited amounts of carbon pollution into the atmosphere. These regulations have been developed under the Clean Air Act, an act of Congress that requires the EPA to take steps to reduce air pollution. But Pam Bondi is fighting it! Bondi told reporters, <blockquote> <h4>Let me tell you who we are looking out for: We are looking out for consumers. And we will continue to look out for our consumers and our businesses, especially when this affects their finances. That's what this is about.</h4> </blockquote> Make no mistake about this. She has no interest in protecting consumers. It’s the power companies that matter. On Tuesday a reporter asked if she believes climate change is man-made, and she replied, <blockquote> <h4>I'm not going to get into a philosophical discussion with you about climate change.</h4> </blockquote> That was a slight breach of etiquette when she actually used the term “climate change” Not to worry! Climate scientists have offered to talk with her about climate change and the damage that could be done if the Clean Power Act were blocked. Her response was no response. Pam Bondi, for fighting against the Clean Power Plan, and for fighting it from a state that will be the first and worst to suffer from climate change...

He has become popular figure in the right-wing political media for his views on social and political issues after a speech at the 2013 National Prayer Breakfast. This year on the 4th of May at a rally in Detroit Carson announced he was running for the Republican nomination in the 2016 presidential election. On 30 September, last week, Carson was asked by a voter in New Hampshire to explain his disbelief in climate change. <div class="mceTemp"> <dl id="attachment_1529" class="wp-caption alignright" style="width: 360px;"> <dt class="wp-caption-dt"><a href="http://www.bluestreakscience.com/wp-content/uploads/2015/10/Dr_Ben_Carson_at_the_Citizens_United_Freedom_Summit_in_Greenville_South_Carolina_May_2015_by_Michael_Vadon_06.jpg"><img class="wp-image-1529 size-medium" src="http://www.bluestreakscience.com/wp-content/uploads/2015/10/Dr_Ben_Carson_at_the_Citizens_United_Freedom_Summit_in_Greenville_South_Carolina_May_2015_by_Michael_Vadon_06-350x350.jpg" alt="A photo of Dr. Ben Carson at the Citizens United Conference" width="350" height="350" /></a></dt> <dd class="wp-caption-dd">Dr. Ben Carson</dd> </dl> </div> The question was: "You don't believe in evolution or climate change, I believe. And I was just wondering, do you seriously not believe that climate change is happening?" The New Republic’s Rebecca Leber reported on Carson’s response, and it was: “Is there climate change? Of course there’s climate change. Any point in time, temperatures are going up or temperatures are going down. Of course that’s happening. When that stops happening, that’s when we’re in big trouble.” He then added, “Just the way the Earth rotates on its axis, how far away it is from the sun. These are all very complex things. Gravity, where did it come from?” Dr. Carson seems confused about what is weather and what is climate. Weather is temperatures going up and down, is it raining or not, and will it rain today. Climate, especially global climate, is a long-term phenomenon that cannot be observed directly in the short term. That fact seems to be lost on him. Carson continued, “As far as evolution is concerned, you know, I do believe in micro-evolution, or natural selection, but I believe that God gave the creatures he made the ability to adapt to their environment. Because he’s very smart and he didn’t want to start over every 50 years.” For a neurosurgeon, Dr. Carson hold some remarkably unscientific views. In fact, in his view science itself is just another religion, and one that he rejects. Regarding science, he stated, “I just don't have that much faith. But they are welcome to believe whatever they want to believe. I'm welcome to believe what I want to believe.” This rejection of the foundation of science would be unacceptable for anyone holding public office, let alone the Presidency. Oh, and we actually do know where <a href="https://en.wikipedia.org/wiki/General_relativity" target="_blank">gravity</a> comes from. It comes from the bending of space-time by massive objects. I don't see a Nobel Prize in your future. Just sayin'.

Shkreli is a 32 year old hedge fund manager specializing in healthcare companies. Shkreli’s company, Turing Pharmaceuticals bought the rights to the toxoplasmosis drug Daraprim last month, and from his responses to the outrage it seems he is embracing his title as the most hated man, and the Blue Streak Science Jackass of the Week. He’s taken to Twitter and hurled insults, calling people “morons”, criticizing Twitter itself by saying that it “seems to be a great medium for socialist and liberal rage”. On 28 September he took to the news shows and argued that Daraprim was grossly underpriced. On Bloomberg he stated, “The price per course of treatment to save your life was only $1,000 and we know these days, [with] modern pharmaceuticals, cancer drugs can cost $100,000 or more, rare-disease drugs can cost half a million dollars.” He seems outraged that the drug was affordable! A reporter reminded him that the pill costs about $1 to manufacture. Hillary Clinton tweeted: "Price gouging like this in the specialty drug market is outrageous. Tomorrow I'll lay out a plan to take it on. -H" Shkreli also has a checkered past with a previous company he was the CEO of...even alledgedly harassing the wife and children of former employee of that company. A sworn affidavit was submitted by this employee to the Supreme Court of the State of New York regarding the alleged harassment. <h3>Shout-outs and Acknowledgments</h3> <a href="http://www.phdcomics.com/movie">The PhD Movie 2: Still In Grad School </a> phdcomics.com/movie This episode of Blue Streak Science Podcast comes to you from Sydney, New South Wales; Atlanta, Georgia; and Santa Rosa, California.

Consequently, Volkswagen, who owns Audi, has taken the lion’s share of the market in the U.S. for diesel cars. For the owners of these cars I have some bad news. They have been pumping 40x the legal amount of nitrogen oxide into our atmosphere. This is all because of software that Volkswagen installed in these cars to intentionally cheat on emissions tests. VW will have to recall all the vehicles and modify the emissions systems at its own expense, regulators said. Additionally it could face a fine of about $18 billion, or $37,500 per car, according to environmental officials. Nitrogen oxide is nasty stuff. It’s one of the primary components of photochemical smog. Smog is not just something that ruins the view of the city. Smog is deadly, and deadly in a big way. It’s particularly harmful for the elderly, children, and people with heart and lung conditions such as asthma. Photochemical smog has been linked to greatly increased rates of low birth weight babies, birth defects, various cancers and the overall death rate. In the province of Ontario, according to the <a href="https://en.wikipedia.org/wiki/Ontario_Medical_Association">Ontario Medical Association</a> smog is responsible for an estimated 9,500 premature deaths in the province every year. It’s bad stuff, that is bad for all of us. But Volkswagen thought they could get away with cheating their customers and the rest of us into have their pollution machines running right under our noses. Here’s what VW did: They rigged the car’s on board computer and sensors to detect the exact conditions of when an emissions test is occurring. Then the computer changed the performance of the car to behave itself during the test and not be spewing pollution as it does in normal operation. Volkswagen is already on record admitting that the cars had “defeat devices”. But this was only after the EPA and California air regulators demanded an explanation. For deceiving your customers, regulators, and wantonly harming the health of millions of people, Volkswagen, you are the Blue Streak Science Jackass of the Week.

It has been ten years since the flooding of Hurricane Katrina devastated the city of New Orleans. The storm made landfall in southeast Louisiana as a category 3 hurricane. And although there have been many stronger storms to strike the Gulf Coast states Katrina exposed decades of neglect of the infrastructure. Levees failed and people died, over 1,200 people. Katrina also exposed the incompetence of a Presidential administration who was more interested in appointing unqualified cronies to emergency management jobs than serving the people of the United States when they most needed their help. Ten years later and it’s been a week of cable news retrospectives and analysis. In the Big Easy it was a week of remembrances and mourning. In a letter to President Obama on 26 August, Governor Bobby Jindal wrote, “This week is a time to mourn the loss of loved ones and the passing of a period in our history. It is also a time to celebrate those whose future has become brighter in the storm’s terrible wake. There is a time and a place for politics, but this is not it. It is therefore with disappointment that I read of the White House’s plans to make this visit part of a tour for your climate change agenda. Although I understand that your emphasis in New Orleans will – rightly – be on economic development, the temptation to stray into climate change politics should be resisted. While you and others may be of the opinion that we can legislate away hurricanes with higher taxes, business regulations and EPA power grabs, that is not a view shared by many Louisianians. I would ask you to respect this important time of remembrance by not inserting the divisive political agenda of liberal environmental activism.” Oh, where to start. First, climate science is not politics. It was politics that left Louisiana defenseless against a category 3 hurricane. If it wasn’t for the all-too-human failure to have basic preparation in place then the name Katrina would only be associated with walking on sunshine. But that’s not climate science. That’s politics. You know what else is political? Doing nothing about climate change when the world’s climate scientists are doing everything in their power to warn us. We’ve been shown the evidence over and over again. Anthropogenic global warming is real. It is happening now, and our children are going to pay dearly for our inaction. Climate science is not politics. It is science. What we do or don’t do about it is politics. Telling the President to shut up about science? Bobby Jindal, you aren’t fooling our listeners here at Blue Streak. You’re running for President in a crowded field for the GOP nomination. And as such you need to appeal to the Republican voters who have become fodder for your party’s elite. If you can get those mouth-breathers who listen to Rush Limbaugh and Michael Savage on your side then perhaps those deep-pocketed GOP donors may take notice and begin writing checks. And what better way to do that than to take an anti-science stance and admonish the President. Red meat for the low-information voters you need for the GOP nomination. So, Governor Bobby Jindal of Louisiana, for taking a cynical and anti-science position on climate change you are the Blue Streak Science Jackass of the Week. <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;">Episode Title</h3> The Completion Backward Principle is the sixth studio album from the rock group <a title="The Tubes" href="https://en.wikipedia.org/wiki/The_Tubes" target="_blank">The Tubes</a>. This was The Tubes' first album for Capitol/EMI and paired the band with producer and songwriter, David Foster in search of a more commercial sound. Many of their A&M albums had been very strong but failed to ignite the charts or build much fan interest beyond their rabid cult. The Completion Backward Principle changed all that with "Talk To Ya Later" (an AOR radio smash) and the chart success of the single "Don't Want To Wait Anymore." A favorite of many Tubes fans, this is a unique album in their catalog in that it married their quirky songwriting and stage persona with a commercial appeal that would be emphasized more heavily on their next project. The breakout that the band had been searching for with their backs to the wall had finally arrived.

More than a million copies of his books are in print in the United States, his work was adapted for film and stage, and he received about 10,000 letters a year. "Dr. Sacks variously described his books and essays as case histories, pathographies, clinical tales or 'neurological novels.' His subjects included Madeleine J., a blind woman who perceived her hands only as useless 'lumps of dough'; Jimmie G., a submarine radio operator whose amnesia stranded him for more than three decades in 1945; and Dr. P. — the man who mistook his wife for a hat — whose brain lost the ability to decipher what his eyes were seeing." Dr. Sacks treated his patients with dignity. To him they weren’t merely just patients with neurological deficits. Each one was a human being with a life, rich in experience and memories, stories of love, of triumphs and tragedies. In February Dr. Sacks announced in the New York Times that the melanoma in his eye had spread to his liver and that he only had months to live. "It is up to me now to choose how to live out the months that remain to me. I have to live in the richest, deepest, most productive way I can," And, in an opinion piece published in the <a href="http://www.nytimes.com/2015/08/16/opinion/sunday/oliver-sacks-sabbath.html?smid=tw-nytimes">Times</a> earlier this month, Sacks wrote: "[N]ow, weak, short of breath, my once-firm muscles melted away by cancer, I find my thoughts, increasingly, not on the supernatural or spiritual, but on what is meant by living a good and worthwhile life — achieving a sense of peace within oneself. I find my thoughts drifting to the Sabbath, the day of rest, the seventh day of the week, and perhaps the seventh day of one's life as well, when one can feel that one's work is done, and one may, in good conscience, rest."

The Obama Administration has given final approval for Shell Oil Company to drill in the Chukchi Sea. Say it ain’t so! This comes just two weeks after the release of the Clean Power Plan, a strong plan to limit greenhouse gas emissions. The President is also going to visit Alaska later this month to highlight the impacts of climate change, which he recently referred to as "one of the greatest challenges we face this century." And now this. I don’t get it. The United States is more self-reliant on energy now than it has been for many decades. The price of oil is bottoming out. There is a glut of oil on the world market. What is the impetus to drill in the Arctic? Again, I don’t get it. Hillary Clinton said in response, “The Arctic is a unique treasure. Given what we know, it’s not worth the risk of drilling.” Exactly, it’s just not worth the risk. President Obama, your record on protecting our natural heritage has been the greatest in the history of the United States. But like the Arctic itself, it can all be spoiled with a bad decision...just one bad decision. So, for putting the once pristine Arctic at risk for no good reason at all, President Obama you are the Blue Streak Science A------ of the Week. <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;">Shout-outs and Acknowledgments</h3> The <a href="http://www.maximumfun.org/shows/can-i-pet-your-dog">Can I Pet Your Dog Podcast</a>!

This time it’s the war against science. It’s no secret that among American conservatives scientific illiteracy has become a source a pride. When faced with science that runs contrary to their cherished views the default position is belligerent denial. From former Senator Todd Akins’ infamous “legitimate rape” statement to virtually anything pumped out by the Heritage Foundation, conservatives have turned the anti-science position from a liability to a winning political strategy.[read more] When you think of a typical science denier, who comes to mind? For me, it’s a conservative who toes the party line on anthropogenic global warming. But the greatest distance between science and the general public is actually over one of the far left’s favorite causes, genetically modified organisms, GMOs. Last January a survey was released by Pew Research that showed 88% of AAAS scientists, think that GMO food is safe to eat, but only 37% of the public agrees with that. Let’s look at a few other places where the extreme left have checked their brains at the door and put on the tin foil hat. I mentioned anti-GMO. There’s also the infamous anti-vaccine crusade, acupuncture, biodynamic agriculture, even most organic agriculture, and homeopathy. One very broad form of science denialism embraced by many in the far left is “chemophobia”. Think The Food Babe. But this chemophobia can have deadly consequences for its adherents. Ariane Forster, better know as Ari Up, of the influential punk band The Slits died in 2010 from breast cancer. According to her stepfather, John Lydon, who himself fronted Sex Pistols. Yes, her stepfather was Johnny Rotten. Lydon told Sky News, “Ariane didn’t need to die. She knew she had cancer and she deliberately ignored it and went for lunatic left-wing crackpot theories. And that will kill you stone dead every single time.” There are countless more examples where innocent, but scientifically illiterate people have suffered terribly and died needlessly because they eschewed the science and instead opted for what some celebrity or website told them. They did their research on the Internet. Is there a progressive war on science? No, not really, insofar the anti-science sentiments on the left are disorganized and have little influence on public policy like it does among conservatives. Climate science denial carries great weight in national Republican politics as evidenced by its prominence in the GOP platform. No equivalent anti-science stance exists in the national Democratic platform. But don’t be fooled. Science denialism and willful ignorance are alive and well on the liberal side. It’s up to us to go where the science leads us, wherever it lead us./read] Today the Blue Streak Science Jackass of the Week, another collective JOTW, are the anti-science moonbats of the political left, wherever you may be. <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;">Shout-outs and Acknowledgments</h3> <a href="https://itunes.apple.com/us/album/never-mind-bollocks-heres/id266317242" target="_blank">"Never Mind the Bollocks"</a> by the <a href="https://en.wikipedia.org/wiki/Sex_Pistols" target="_blank">Sex Pistols</a> The Story Worthy Podcast at <a href="http://www.storyworthypodcast.com">www.storyworthypodcast.com</a> Please visit <a href="http://www.biodetectives.co.uk/" target="_blank">BioDetectives</a> as they track life science stories from Down Under to Up North.

Be Silent No More!
I just read a piece by John D. Sutter on CNN’s website titled, “Woodward County, Oklahoma: Why do so many here doubt climate change?” This county has among the highest rates of those who do not accept climate change as real. From his conversations in Woodward County Mr. Sutter assumed that between 70-90% of residents believed climate change is a myth. Most of the residents of the county believed that number, too...that the great majority of their neighbors just don’t buy into the idea that climate change is happening. The reality on the ground is that according to Yale research only 30% of people there think climate change is bogus. But because the anti-science voices tend to be the loudest, the average person, the majority, stay silent. When you remain silent you give the impression of agreement, of complicity. And nationally, only 18% of people refuse to accept the scientific consensus on climate change. What we have here is a tin-foil hat wearing, conspiracy-believing minority...a small minority. A radical fringe. Like anti-vaxxers. You are the majority. You understand how science works and you understand the consequences of doing nothing.

Climate Science with Greg Laden
Recently NASA announced the discovery, for the first time, of an Earth-like planet orbiting a star like our own Sun 1,400 light years distant. The planet is a bit larger and older than earth, and it occupies the “habitable zone”, where conditions are optimal to make life a possibility. <div class="mceTemp" style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif; font-size: 16px; line-height: 24px;"><dl id="attachment_1305" class="wp-caption alignright" style="width: 410px;"><dt class="wp-caption-dt" style="-webkit-user-drag: none;"><a style="-webkit-user-drag: none;" href="http://www.bluestreakscience.com/wp-content/uploads/2015/08/Kepler-452b_System400x282.jpeg"><img class="size-full wp-image-1305" style="margin: 0px; padding: 0px; border: 0px none; -webkit-user-drag: none;" src="http://www.bluestreakscience.com/wp-content/uploads/2015/08/Kepler-452b_System400x282.jpeg" alt="Kepler 452b system" width="400" height="282" /></a></dt><dd class="wp-caption-dd" style="font-size: 11px; line-height: 17px; padding: 0px 4px 5px; margin: 0px; -webkit-user-drag: none;">Kepler 452b system</dd></dl></div> Right now I’m sure that spectral analysis is being conducted to see if this planet has an oxygen-rich atmosphere, a strong indicator of life. Moreover, I’d bet good money that radio telescopes are being pointed toward Kepler 452b in hopes that maybe, just maybe there’s an intelligent species there who are using radio signals for communication. Perhaps these creatures are like us in many ways...just a little more than a century from the discovery of broadcast radio and now maybe they’re enjoying technologies similar to our satellites, Internet, and smartphones. Perhaps they’ve sent astronauts to their moon or nearby planets, and have a space probe that has recently made a flyby to their outermost planet, even arguing about whether it’s a real planet or not. And perhaps, just perhaps, they’re analyzing data from one of their space telescopes and have just announced the discovery of planet similar to their own, only smaller, a bit younger, and 1,400 light years distant. In other words, they’re looking right back at us. Right now their scientists are pointing radio telescopes to listen for radio signals to determine if a civilization exists on Earth. What’ll they hear? Crickets. And what will we hear when we listen to them? Space crickets. Those radio signals, even if we both have the technology to hear them, won’t reach our respective planets for almost 1,300 years. We could be staring right at each other and never know it.

The Blue Streak Bucket List
The desire, the yearning for answers lies within each of us. The discomfort of not knowing the answers can lead us down many paths of beliefs and behaviors. Our discomfort at not knowing everything immediately has given us 24 hour cable news, and smartphones never outside of our reach. It’s given us our social media, news websites…one more peek at the smartphone before we drift off to sleep…only to reach for the smartphone the very moment we awake. When a major tragedy happens in the world this discomfort of not knowing everything about it can result in obsessive media watching. And when the news outlets have repeated ad nauseam every known detail about the tragedy, and fill in the gaps with gratuitous speculation still they continue on. Conspiracy theories, cultural bigotry, meteors, terrorist plots…no amount of speculation is too outlandish, ugly, or improbable to breathlessly blather while the ever-believing public look for answers...any answers. We must accept that when we don’t know, we just don’t know. Conjecture, religion, superstition and conspiracy theories may fill the void, but you must consider what you are being filled with. Don’t get comfortable with not knowing. Scratch that itch, feed that jones, but feed it with rationality. Nourish it with science. The answers may be a long time coming. They may never come at all. But the comfort that science and reason provide the curious mind will always be more satisfying and fulfilling than the emptiness of ignorance. <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;"><a href="http://www.bluestreakscience.com/wp-content/uploads/2015/07/bucketlist01.png"><img class="alignright size-medium wp-image-1293" style="float: right;" src="http://www.bluestreakscience.com/wp-content/uploads/2015/07/bucketlist01-350x350.png" alt="bucketlist01" width="350" height="350" /></a>Announcement of the Blue Streak Bucket List</h3> <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;">Blue Streak Science News</h3> <ul style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif; font-size: 16px; line-height: 24px;"> <li>Pentaquark discovered by LHC</li> <li>Catalog of DNA modifications produces surprises</li> <li>Metal Foams Can Shield Against Gamma, X-rays?</li> <li>Enormous quantities may soon be called 'genomical'</li> <li>As Climate Warms Hawaiian Forest Birds Lose More Ground to Mosquitoes</li> <li>Stephen Hawking and Yuri Milner Announce $100M Initiative to Seek ET</li> </ul> <h3 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif;">The A$$---- of the Week is Fran Drescher</h3> <h4 style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif; font-size: 16px; line-height: 24px;"><a href="http://www.thefarmersdaughterusa.com/2015/07/that-time-fran-drescher-tweeted-about-gmos.html" target="_blank">That Time Fran Drescher Tweeted About GMOs</a></h4> We have a guest on the A$$---- of the Week!

Citizen Science
Citizen Science. Sounds good, but what is it? Citizen science happens when a member of the general public, a person who is not a professional scientist, collects or analyzes data relating to the natural world, and most importantly shares it with the science community and the public. There are so many ways each of us can participate. <div class="mceTemp" style="color: #333333; font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif; font-size: 16px; line-height: 24px;"><dl id="attachment_1197" class="wp-caption alignright" style="width: 360px;"><dt class="wp-caption-dt" style="-webkit-user-drag: none;"><a style="-webkit-user-drag: none;" href="http://www.bluestreakscience.com/wp-content/uploads/2015/07/birders.jpg"><img class="size-medium wp-image-1197" style="margin: 0px; padding: 0px; border: 0px none; -webkit-user-drag: none;" src="http://www.bluestreakscience.com/wp-content/uploads/2015/07/birders-350x233.jpg" alt="Citizen Scientists" width="350" height="233" /></a></dt><dd class="wp-caption-dd" style="font-size: 11px; line-height: 17px; padding: 0px 4px 5px; margin: 0px; -webkit-user-drag: none;">Citizen Scientists</dd></dl></div> Possibly the largest and oldest example of a citizen science project is the Christmas Bird Count administered by the National Audubon Society in North America. It has been held since 1900 and now has over 50,000 citizen scientists making observations. The purpose of the bird count is to provide population data for use in conservation biology. You amateur astronomers are amazing! New comets are being discovered all the time, stars even. Those mysterious plumes seen rising from Mars last February probably would have been missed completely if it weren't for amateur stargazers. In episode nine of the podcast, that’s next week, Blue Streak Science is going to start its own citizen science project in which you, our dear listeners and blog readers, can participate. It’s going to be all about observation, participation, and sharing. In the meantime...clean lenses and quick focusing.

However, when naturopathy is put in place of science-based medicine the results are often harmful, even deadly. The baby boy lost more than a kilogram and was near death. New South Wales police arrested Bodnar, a 59 year old registered nurse and midwife, and are investigating her Leppington practice over her treatment of children. The mother was seeking alternative healthcare for her baby boy who was suffering from eczema. Bodnar advised the mother to cease all of the baby’s medical treatment. The child was admitted to hospital in May and was near death from malnutrition and now has developmental issues. The boy was released from hospital 8 July. Child Abuse Squad detectives arrested Bodnar on 9July in Leppington and have charged her with reckless grievous bodily harm in the second degree, and aiding and abetting failing to provide for a child causing danger of death. The mother is also facing the same charges. A statement from NSW Health stated that naturopaths are unregistered health practitioners and are subject to a code of conduct under the Public Health Act and Regulation. They are required to provide services in a safe and ethical manner, and not to attempt to dissuade clients from seeking or continuing with treatment by a registered medical practitioner. This is another example of how an adult's scientific illiteracy can be deadly. In this example, it is a child..a baby...that has suffered so grievously.

006: Implausible Denial
Science denial. It’s nothing new. Pope Urban VIII imprisoned Galileo out of anger and fear; a denial of the truth. Two and a half centuries later Charles Darwin publishes The Origin of Species and the fundamentalist shit hits the biblical fan. One-hundred fifty years later there are still those who deny the scientifically undisputed fact of biological evolution. There are many other examples, but let me get to the big one. Climate change. That seems to be the denial du jour. In the face of a near unanimous worldwide consensus among climate scientists the denialists are stalwart. Hands over ears and screaming la-la-la-la-la. And that leads me to what all of these instances of science denial have in common. A challenge to a strongly held belief, or worldview. These beliefs were once the only way of coming to terms with nature and the universe. But then science came along and ruined everything. As a valid way of looking at nature these beliefs are dead. They have ceased to be! Bereft of life, they rest in peace. And what happens when someone or something dear to you dies. You mourn it. It’s a natural human reaction. We then go through the five stages of grief until we come to terms with the new reality. What’s the first stage of grief? Yep, denial. “No, no, my mother didn’t just run off to Tahiti with the postman!” No. We reject the idea. We find alternatives. “Oh, she’s at the grocery store…she’s been gored by a bull in Pamplona”. Anything other than the unacceptable truth. See the parallel? The global warming denialists are going ape-shit. They can’t accept the truth. So they are coming up with crazy, insane ideas like, “ooh, it’s a big conspiracy by lefty climate scientists all over the world to destroy America,” or “Al Gore is a commie pinko and this is an evil plot to take away our freedom...and our guns!” Anything but the reality that upsets their long-held belief. But just like someone who is mourning the death of a loved one, they know. They know deep inside that they have to face a new reality. It’s too painful, so no justification is too insane for them to grasp on to. Then they’ll vacillate between anger and denial for a while before moving on to bargaining. “If only I hadn’t put the recyclables into the trash," or “If only I had listened to the Blue Streak Science Podcast and sent them lots of money, the polar bears would be saved!” When the climate denialists see the futility of bargaining they will get depressed. Who the hell wouldn’t? In a journal article this week a group of scientists warned that because of global warming, sea levels will rise so much that parts of Florida will be under water. The bad news? Parts of Florida won't be under water. As all of us know who’ve ever experienced a tragedy or major setback in life there comes a point of acceptance. Don’t expect the deniers to join Greenpeace, buy a Prius, or even sort their recycling. Acceptance of an inconvenient truth is often a quiet and personal realization. <hr /> <h2>Science News with Kellie Vinal and Sophie McManus</h2> <ul> <li>Mmmm...split bee soup!</li> <li>Dental pulp cell transplants help regenerate peripheral nerves</li> <li>Sailing spiders</li> <li>Shearwaters find their way home by scent</li> <li>Spit test could provide early warning of head, neck cancers</li> <li>Cuba named 1st country to end mother-to-child HIV transmission</li> <li>Lion facial recognition debuts in Africa</li> </ul> <hr /> <h2>Asshole of the Week</h2> Canadian-American actor and comedian and one of the most popular comic actors today is the recipient of Blue Streak Science Asshole of the Week award. I first noticed Jim Carrey in the 1988 film "Earth Girls Are Easy" in which he and Damon Wayans had relatively minor roles. Jim Carrey's resume includes: <ul> <li>Sketch comedy show In Living Color (1990) in which he rejoined Damon Wayans along with the Wayans family</li> <li>Ace Ventura series of films</li> <li>The Mask (1994)</li> <li>He played the Riddler in Batman Forever (1995)</li> <li>The Truman Show (1998)</li> </ul> Mr. Carrey was in a relationship with the infamous anti-science, anti-vaccination celebrity Jenny McCarthy from 2006 until 2010. Celebrities like Jim Carrey often use their visibility and high profile to push their causes. Right or wrong, they have influence on legions of fans. In response to epidemics of measles and whooping cough the California state assembly put together a bill that makes vaccinations mandatory for all school children, public and private. The "personal belief" exemption was eliminated. Last week Governor Jerry Brown signed the bill into law, and Jim Carrey has taken Twitter to vent his anger regarding these new protections for California's children, uninformed as it may be. The star of the Dumb and Dumber films has been a vocal opponent of vaccinations since his relationship with Jenny McCarthy. In spite of overwhelming scientific evidence against it Carrey and McCarthy believe her son developed autism from vaccinations. On 30 June Carrey proved that he's still talking out of his ass when he wrote on Twitter: "California Gov says yes to poisoning more children with mercury and aluminum in manditory [sic] vaccines. This corporate fascist must be stopped." He followed up with "they say mercury in fish is dangerous but forcing all of our children to be injected with mercury in thimerosol [sic] is no risk. Make sense?" Firstly, according to the Centers for Disease Control: Since 2001, no new vaccine licensed by FDA for use in children has contained thimerosal as a preservative. Exercising an abundance of caution, the FDA eliminated Thimerosal as a vaccine preservative based on methylmercury studies. However, upon injection Thimerosal is metabolized into ethylmercury. It has since been found that ethylmercury is eliminated from the body and the brain significantly faster than methylmercury, so the late-1990s risk assessments turned out to be overly cautious. These are biochemical details that seem lost on the anti-science celebrities and those who give credence to what they have to say. Unfortunately, there's no vaccine for stupidity. Carrey's Twitter invective continued and we finally got to the real motivation behind it. In one of the tweets Mr. Carrey promoted a 2014 anti-vaccination movie, which will remain unnamed. It seems the producers of the film have taken advantage of the publicity surrounding the signing of the vaccination law to do some promotion. They've targeted celebrities like Jim Carrey who were more than willing to go along with it. Let's say you're a comic actor and a celebrity whose best years are behind you. You desperately want to stay relevant. So you reprise a film role from more than 20 years ago. You keep yourself in the public eye by going on social media diatribes with an anti-science rant. No more Golden Globes. An Oscar? You can forget about that now. Let me show ya somethin', Jim Carrey. Here is an award you can place on your mantle.

005: Free Education
From kindergarten through 12th grade every child in the United States has the right to attend school free of charge. But should we have a right to a college education? I assert that every child and every person has the right to higher education. This year President Obama proposed to make community college free for many students. But even this small, incremental step toward free education has virtually no chance in the harsh reality of a do-nothing Congress. Still, I do believe that opening the topic for discussion is beneficial. After all, we will one day return to having a Congress who puts the interests of the people first. It will happen. Why would we even want to foot the bill for higher education? It’s expensive and what benefit would it confer on the betterment of American society? Per capita income rises sharply in regions that have a higher rate of college graduates. This means better and higher paying jobs, higher property values, lower crime, lower rates of incarceration and the associated expenses of that, and more taxes paid to local government. In other words, greater wealth for both the individual and for the state in which they live. Also, those with a college education often become lifetime learners, willing and eager to keep up with the latest training in their fields, and much more able to pivot to another career in a rapidly changing world economy. It’s a highly competitive world out there, and the overall benefit of free college is a citizenry who are more competitive with other nations. There are hundreds of thousands of American high school students with so much untapped potential, the potential to make their lives and our country a better place. They are unable to continue on to a college or university because they and their families cannot afford the prohibitive costs, or take on the crippling debt. These students will likely never reach their full potential. But we can change all that. Ah, but the cost. Beyond the states and nation as a whole, and the individual student, who benefits the most from an educated citizenry? Who stands to profit the most? Large Corporations. Large corporations often gain a financial benefit off the backs of students and their families. It’s time they pay their fair share and they must play a substantial role in funding the higher education from which they gain so much profit. The federal government, the states, and large corporations can make this a success But until then, get out and vote! Because these progressive changes can only happen if we elect real leaders who are willing to make it happen. <hr /> <h2>Science News with Kellie Vinal and Sophie McManus</h2> <ul> <li>Evidence in support of medical marijuana?

Gibson is an Australian 'alternative health' 'wellness' advocate who reportedly squirreled away hundreds of thousands of dollars that she's earnt from her app and cookbook. So far, so celebrity food culture? Not quite. Belle Gibson has for years claimed to have brain cancer that she 'self-treated' with such gold as 'the power of fruits and vegetables', colonic irrigation etc, eschewing traditional cancer treatments. She also claimed she had two heart operations, that her heart had stopped on the operating table, and she had had cancer of the blood, uterus and spleen. Around March/April this year it became apparent that this was complete and utter bull*%#t only AFTER it was revealed she had failed to donate 25% of her profits to charity. She reportedly kept all of the cash to fund a lavish lifestyle. Speaking of cash, Gibson made a fortune - some estimates put the sum around about a cool million dollars - she has made her money by flogging her 'wellness' theories to people who actually have cancer, encouraging patients to adopt her recipes and shun radiotherapy When her donation claims were investigated, so was her health - her publisher never fact-checked her story as they took her on good faith... Last year she said she had been diagnosed with a third and fourth cancer: 'One is secondary and the other is primary. I have cancer in my blood, spleen, brain, uterus, and liver. I am hurting' In a turnaround she now claims to have been 'misdiagnosed' and to have suffered trauma from this....(the heart bleeds). In April she said 'none of it's true' after first insisting that her brain cancer was genuine, but the other cancers were a figment. Cancer sufferers are angry that she received money (disputed sum?) for an interview on Australian TV show 60 minutes aired this weekend, during which she refused to apologise - she appears to be a very confused individual, but that's no excuse as she is someone who may well have damaged patients' health through peddling her twisted agenda. It seems doubtful that she should have been on TV in the first place. So Belle is awarded the glittering tiara of the A***ole of the Week.

004: Are Children Born Scientists?
We romanticize childhood in so many ways. For example, we look at our children and see little scientists. After all, they’re naturally curious and they even conduct basic experiments that help them to understand their surroundings. Most of us can remember our own childhoods and how the novelty of almost everything in our world fascinated us. Why is the sky blue? How deep is the ocean? Why do boats float and planes fly? Our childhood experiments often delved into biology. You toss the fly into the spider’s web and see what happens. The spider dashes across its web for a tasty meal. Can’t find a fly to lob into the web? You throw in a small twig and wait, but nothing happens. A few repetitions of this experiment and the child version of you is already submitting a paper to the Journal of Arachnology. But that’s where the similarities end. The real reason that children are not natural scientists is because of their unfortunate, but natural tendency to believe what adults tell them. But the scientific mind always reserves some doubt for what it observes. Becoming a scientist requires that we overcome our natural tendency, our childish tendency, to just believe. Kids may start off on the right track with their curiosity, but they must learn and practice some counterintuitive abstract skills before they can enjoy the benefits of a life of scientific thinking, maybe even becoming a scientist herself Most adults struggle with scientific thinking, but that’s not because they’ve lost any natural ability they once had. It’s because they never progressed in their education, or were never required to, or were even discouraged from learning these analytical and abstract skills that are the hallmark of the scientific mind. <hr /> <h2>On This Week’s Show</h2> <ul> <li>New Guest Blogger, Louise O'Regan</li> <li>Blue Streak Science News</li> <li>Asshole of the Week</li> </ul> <hr /> <h2>Science News with Kellie Vinal and Sophie McManus</h2> <ul> <li>Why some Ebola strains are more dangerous than others</li> <li>Antibiotics an alternative to surgery for appendicitis</li> <li>Kangaroos are southpaws</li> <li>A smart insulin patch for diabetes</li> <li>The rise of multi-cellularity</li> <li>Facebook can recognise us even when we shield our faces!

Ann Coulter, the conservative mouthpiece and author of the new anti-immigration book whose title I will not divulge, because I cannot in good conscience, promote what she does. I get queasy even mentioning her on Blue Streak. She recently voiced her disdain for both immigrants and female voters on the radio show called “Free Speech” with Gavin McInnes. Interesting is that McInnes himself is an immigrant from Canada So, McInnes brought up the topic of women voters and this prompted Coulter to share her view that “women should not have the right to vote.” She went further to state that while women should not vote, “We can still write books! We can run for office.” Why is a person who holds such backward views even relevant? The sad reason that she is still on the conservative talk circuit is because she is one of the primary voices of American conservatism, and the Republican Party.

003: The Distractingly Sexy Episode
On the day of his inauguration in 1961 President John F. Kennedy proclaimed that the torch of American idealism had been passed to a new generation. He called on Americans of all walks of life to come together in self-sacrifice to fight tyranny, poverty, disease, and even war itself. And growing up I thought my generation was going build upon those brave efforts...that we would be a generation to lead the world by example. We could have ridden that wave of the 1960’s...the successes of civil rights legislation, desegregation, environmentalism, gender equality, and sexual and reproductive rights. But something happened in the 1980’s. Just as my generation began embarking on their careers our country took a hard turn to the right, to the religious right. It was the goal of Reverend Jerry Falwell and his self-anointed Moral Majority to elect right-wing Christian politicians to evangelize in the halls of Congress, the White House, and even in the Supreme Court And boy howdy did they succeed And so it has been for over 30 years, a new brand of conservative, standing against and sometimes rolling back the hard-won progress of American idealism. Efforts by the religious right to use public institutions to do their proselytizing came one after another. Often times it has been only the Constitution that has protected us from the tyranny of an American-born theocracy Here we are in 2015. A new generation is here. The Millennials. Born from from about 1982 to 2004, Millennials are already the largest living generation. But are they really any different from the generations that came of age during the forging of America’s alliance between politicians and the religious right? According to a Pew Research Center study released in March of 2014, the fastest growing religious cohort in America are those who check the box for “no religious affiliation”. These numbers have been rising steadily since the 1990’s, when they were in the single digits, to the present 23 percent of adults of all ages with no religious affiliation. Also, there’s been a 7% jump just since 2007. And here come our Millennials. Fully 34 percent put themselves in the “none of the above” category when it comes to religion. The Pew study also found that they’re the best-educated segment of young adults in American history, and 49% of millennials think America’s best years are ahead of it. They are much more optimistic that my generation has ever been. That’s amazing to me since we’ve passed on to them a world choking on the excesses of our unbridled consumerism, stripping and polluting the world for short-term gains Better educated, more optimistic, embracing science and shunning superstitions. Now more than ever, and because of them I share their optimism for the future, to see the world and universe as it really is, not as they hope it will be or how some Bronze Age text tells them it is. I admire the Millennials' willingness to make the changes and the sacrifices we and previous generations refused to make. So that they can proudly pass the torch of American idealism to the next generation along with a world that is healthier than the one they inherited. <h2>On This Week’s Show</h2> <ul> <li style="font-weight: 400;">The Millennials</li> <li style="font-weight: 400;">Blue Streak Science News</li> <li style="font-weight: 400;">A***ole of the Week</li> </ul> <h2>Science News with Sophie McManus and Kellie Vinal</h2> <ul> <li style="font-weight: 400;">A rat forelimb has been grown in the lab!

"Let me tell you about my trouble with girls. Three things happen when they are in the lab: you fall in love with them, they fall in love with you, and when you criticise them they cry." Those are the words of Sir Tim Hunt to the World Conference of Science Journalists in South Korea. Why do we even give a crap about Tim Hunt? Tim Hunt received the Nobel Prize in 2001 for his discoveries in cell division But we’re not going to talk about that now, because Tim Hunt has stepped in some deep shit I’m sure he’s backed off his statement...maybe he had just finished binge-watching Mad Men or just momentarily thinking of himself as the Hugh Hefner of Nobel laureates Nope! It looks like Timmy has doubled down instead. Sure he told BBC Radio 4 that he apologizes for any offense that was taken, but he said he had "meant to be honest". It’s the classic “I’m sorry you’re offended” apology seemingly purloined directly from the playbook of conservative American politicians after they give their expert opinions on female anatomy and reproduction. He has stated that the remarks were "intended as a light-hearted, ironic comment" but had been "interpreted deadly seriously by my audience". "I did mean the part about having trouble with girls," he said. He continues, "It is true that people - I have fallen in love with people in the lab and people in the lab have fallen in love with me and it's very disruptive to the science because it's terribly important that in a lab people are on a level playing field. "I found that these emotional entanglements made life very difficult. Putting aside the content of his initial statements, and his lack of genuine apology. Level playing field? Really? You are calling your female colleagues “girls”. Do you call your male colleagues “boys”? My guess is that you don’t. Is that what you mean by a level playing field? You have earned yourself a spot in the newly created male chauvinist douchebag wing of our hall of shame.

You’re female. Your adviser can’t seem to stop looking at your boobs. What do you do? There’s an advice column in the Science Careers section of the journal Science – It’s called “Ask Alice”. Their advice? You should probably “just put up with it”. That’s right, Alice Huang suggests you just put up with it. This is Dr. Alice Huang, a microbiologist and former president of the American Association for the Advancement of Science. Let’s go to the original question asked in the column: “I’ve just joined a new lab for my second postdoc. It’s a good lab. I’m happy with my project. I think it could really lead to some good results. My adviser is a good scientist, and he seems like a nice guy. Here’s the problem: Whenever we meet in his office, I catch him trying to look down my shirt. Not that this matters, but he’s married. What should I do?” Here’s part of the reply: “Imagine what life would be like if there were no individuals of the opposite—or preferred—sex. Well, like it or not, the workplace is a part of life. As long as your adviser does not move on to other advances, I suggest you put up with it, with good humor if you can. His attention on your chest may be unwelcome, but you need his attention on your science and his best advice.” Thankfully, Science retracted the column, and replied with, “We regret that the article had not undergone proper editorial review prior to posting. Women in science, or any other field, should never be expected to tolerate unwanted sexual attention in the workplace.” Good on you, Science, for retracting that awful advice and responding quickly and unequivocally. However you, Dr. Alice Huang, there’s just no excuse for such awful advice. None. – And for that, you have earned yourself a place as the Blue Streak Science A***ole of the Week. <hr /> <h2>Recommended by The Team</h2> <h3>The Book Diva’s Reads</h3> Find this great website at <a href= "http://www.thebookdivasreads.com/">www.bookdivasreads.com</a> “It is what you read when you don’t have to that determines what you will be when you can’t help it”. -Oscar Wilde If you love to read for the pure joy of it then you must bookmark this website.

Who is Jeb Bush? He may not be too well-known outside of North America, but he is the former governor of Florida and likely 2016 Republican presidential candidate. Oh, and he’s the brother of former U.S. President George W. Bush, the one that got us into two wars, destabilized the Middle East, and precipitated the Great Recession. Remember? Yeh, his brother. Jeb Bush is now acknowledging that the climate is changing, but claims that whether or not humans have caused this is still unclear. Bush made these comments at a house party in New Hampshire, and not long after President Obama urged the government to act toward mitigating the immediate risk of climate change. Jeb Bush stated, “Look, first of all, the climate is changing. I don’t think the science is clear what percentage is man-made and what percentage is natural. It’s convoluted. And for the people to say the science is decided on, this is just really arrogant, to be honest with you.” He went on to say that this “intellectual arrogance” was preventing people from having a conversation on anthropogenic climate change. Let’s step back and have a brief look at the science. According to NASA nearly all climate scientists agree that global warming over the last century is “very likely” caused by human activities. This statement by NASA cites 18 different scientific institutions. Nine out of the 10 warmest years on record have occurred since 2000, with 2014 being Earth’s warmest year on record. Holly Shulman, a spokeswoman for the Democratic National Committee said, “Ninety-seven percent of climate scientists agree that human activity has led to climate change. Ninety-seven percent. But Jeb Bush thinks they’re wrong. Who’s being intellectually arrogant now? Hot enough for ya, Jeb Bush?
