Up until now, epilepsy treatments have focused on taming seizures rather than the source of the disease and for good reason—so many roads lead to epilepsy: traumatic brain injury, extreme fever and infection, and genetic disorders, to name a few. Staff Writer Jennifer Couzin-Frankel talks with host Sarah Crespi about researchers that are turning back the pages on epilepsy, trying to get to the beginning of the story where new treatments might work. And Sarah also talks with Torsten Neurbert at the Technical University of Denmark’s National Space Institute in Kongens Lyngby about capturing high-altitude “transient luminous events” from the International Space Station (ISS). These lightning-induced bursts of light, color, and occasionally gamma rays were first reported in the 1990s but had only been recorded from the ground or aircraft. With new measurements from the ISS come new insights into the anatomy of lightning. This week’s episode was edited by Podigy.

Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates. Sarah also talks with Dante Lauretta, principal investigator for NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It’s extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft’s mission. This week’s episode was edited by Podigy.

And up until now, that’s pretty much how scientists have tracked landslides—roadside observations and spotty satellite images. Now, researchers are hoping to track landslides systematically by instrumenting an entire national park in Taiwan. The park is riddled with landslides—so much so that visitors wear helmets. Host Sarah Crespi talks with one of those visitors—freelance science journalist Katherine Kornei—about what we can learn from landslides.

Aboard the ship and on the nearby ice, researchers will take measurements of the ice, air, water, and more in an effort to understand this pristine place. Science journalist Shannon Hall joins host Sarah Crespi to talk about her time aboard the Polarstern and how difficult these measurements are, when the researchers’ temporary Arctic home is the noisiest, smokiest, brightest thing around. After that icy start, Sarah talks also with Tanmoy Samanta, a postdoctoral researcher at Peking University in Beijing, about the source of the extreme temperature of the Sun’s corona, which can be up to 1 million K hotter than the surface of the Sun. His team’s careful measurements of spicules—small, plentiful, short-lived spikes of plasma that constantly ruffle the Sun’s surface—and the magnetic networks that seem to generate these spikes, suggest a solution to the long-standing problem of how spicules arise and, at the same time, their likely role in the heating of the corona.

Researchers are now using the tools of archaeology to learn more about the day-to-day lives of enslaved Africans—how they survived the conditions of slavery, how they participated in local economies, and how they maintained their own agency. Host Sarah Crespi talks with Contributing Correspondent Lizzie Wade about a Caribbean archaeology project based on St. Croix in the U.S. Virgin Islands and launched by the founders of the Society for Black Archaeologists that aims to unearth these details. Watch a related video here. Sarah also talks with Jonathan Schulz, a professor in the Department of Economics at George Mason University in Fairfax, Virginia, about a role for the medieval Roman Catholic Church in so-called WEIRD psychology—western, educated, industrialized, rich, democratic. The bulk of psychology experiments have used participants that could be described as WEIRD, and according to many psychological measures, WEIRD subjects tend to have some extreme traits, like a stronger tendency toward individuality and more friendliness with strangers.

As many as 100,000 people die from the disease each year. For those who survive infection, the virus leaves a lasting mark—it appears to wipe out the immune system’s memory. News Intern Eva Fredrick joins host Sarah Crespi to talk about a pair of studies that looked at how this happens in children’s immune systems. Read the related studies in Science and Science Immunology. In our second segment this week, Sarah talks with Todd Thompson, of Ohio State University in Columbus, about his effort to find a small black hole in a binary pair with a red giant star. Usually black holes are detected because they are accruing matter and as the matter interacts with the black hole, x-rays are released. Without this flashy signal, black hole detection gets much harder. Astronomers must look for the gravitational influence of the black holes on nearby stars—which is easier to spot when the black hole is massive.

Sarah also talks with Jennifer Gruhn, a postdoctoral research fellow at the University of Copenhagen Center for Chromosome Stability, about counting chromosomes in human egg cells. It turns out that cell division errors that cause too many or too few chromosomes to remain in the egg may shape human fertility over our reproductive lives. Finally, in this month’s book segment, Kiki Sanford talks with Daniel Navon about his book Mobilizing Mutations: Human Genetics in the Age of Patient Advocacy.

This sweet, soulful look might very well have been bred into canines by their intended victims—humans. Online News Editor David Grimm talks with host Meagan Cantwell about a new study on the evolution of this endearing facial maneuver. David also talks about what diseased dog spines can tell us about early domestication—were these marks of hard work or a gentler old age for our doggy domestics? Also this week, host Sarah Crespi talks with Michel Marechal of the University of Zurich in Switzerland about honesty around the globe. By tracking about 17,000 wallets left at hotels, post offices, and banks, his team found that we humans are a lot more honest than either economic models or our own intuitions give us credit for.

It did just that in 2012. But the question on many physicists’ minds about the LHC is, “What have you done for me lately?” Host Sarah Crespi talks with Staff Writer Adrian Cho about proposals to look at the showers of particles created by its proton collisions in new ways—from changing which events are recorded, to changing how the data are analyzed, even building more detectors outside of the LHC proper—all in the hopes that strange, longer-lived particles are being generated but missed by the current set up. Also this week, Sarah talks with Tian Li of the University of Maryland in College Park about a modified wood designed to passively cool buildings. Starting from its humble roots in the forest, the wood is given a makeover: First it is bleached white to eliminate pigments that absorb light. Next, it is hot pressed, which adds strength and durability. Most importantly, these processes allow the wood to emit in the middle-infrared range, so that when facing the sky, heat passes through the wood out to the giant heat sink of outer space.

Host Meagan Cantwell is joined by freelance journalist Christa Lesté-Lasserre to discuss what might be causing these injuries and when the track might reopen. In our second segment, researchers are racing to understand the impact of jailing people before trial in the United States. Host Sarah Crespi talks with Online News Editor Catherine Matacic about the negative downstream effects of cash bail—and what research can tell us about other options for the U.S. pretrial justice system. Last up is books, in which we hear about the long, sometimes winding, roads that food can take from its source to your plate. Books editor Valerie Thompson talks with author Robyn Metcalfe about her new work, Food Routes: Growing Bananas in Iceland and Other Tales from the Logistics of Eating.

Host Meagan Cantwell talks with Staff Writer Paul Voosen about the first deep-sea test of a bus-size machine designed to scoop up these nodules, and its potential impact on the surrounding ecosystem. In an expedition well above sea level, the Hayabusa2 spacecraft touched down on the asteroid Ryugu last month. And although the craft won’t return to Earth until 2020, researchers have learned a lot about Ryugu in the meantime. Meagan speaks with Seiji Sugita, a professor at the University of Tokyo and principal investigator of the Optical Navigation Camera of Hayabusa 2, about Ryugu’s parent body, and how this study can better inform future asteroid missions.

About the Science Podcast [Image: NASA Scientific Visualization Studio; Music: Jeffrey Cook] 29:24 Scientific Community Science no ‘The Tragedy of the Commons’ turns 50, and how Neanderthal DNA could change your skull http://traffic.libsyn.com/sciencemag/SciencePodcast_181214.mp3 In 1968, Science published the now-famous paper “The Tragedy of the Commons”?by ecologist Garrett Hardin. In it, Hardin questioned society’s ability to manage shared resources, concluding that individuals will act in their self-interest and ultimately spoil the resource. Host Meagan Cantwell revisits this classic paper with two experts: Tine De Moor, professor of economics and social history at Utrecht University in the Netherlands, and Brett Frischmann, a professor of law, business, and economics at Villanova University in Pennsylvania. They discuss how premodern societies dealt with common resources and how our current society might apply the concept to a more abstract resource—knowledge. Not all human skulls are the same shape—and if yours is a little less round, you may have your extinct cousins, the Neanderthals, to thank. Meagan speaks with Simon Fisher, neurogeneticist and director of the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, about why living humans with two Neanderthal gene variants have slightly less round heads—and how studying Neanderthal DNA can help us better understand our own biology.

But in the past decade researchers have started to look elsewhere in the body for clues to this debilitating disease—particularly in the gut. Host Meagan Cantwell talks with Viviane Labrie of the Van Andel Institute in Grand Rapids, Michigan, about new research suggesting people without their appendixes have a reduced risk of Parkinson’s. Labrie also describes the possible mechanism behind this connection. And host Sarah Crespi talks with Peter Fratzl of the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, about what materials scientists can learn from nature. The natural world might not produce innovations like carbon nanotubes, but evolution has forged innumerable materials from very limited resources—mostly sugars, proteins, and minerals. Fratzl discusses how plants make time-release seedpods that are triggered by nothing but fire and rain, the amazing suckerin protein that comprises squid teeth, and how cicadas make their transparent, self-cleaning wings from simple building blocks.

Now, Indigenous people are exploring how this type of study can be conducted in a way that respects their people and traditions. Meagan Cantwell talks with contributing correspondent Lizzie Wade about a summer workshop for Indigenous scientists that aims to start a new chapter in genomics. We’ve known for decades that PCBs—polychlorinated biphenyls—are toxic and carcinogenic. In the 1970s and 1980s, these compounds were phased out of use in industrial and electronic applications, worldwide. But they are still in the environment—in soil and air—and in animal tissues, particularly those of killer whales. These toxic compounds start out at minute levels in tiny organisms, but as the small are eaten by the slightly larger, the PCB concentration increases—from plankton, to fish, to seals—until you are at killer whales with PCB-packed blubber. Ailsa Hall, director of the Sea Mammal Research Unit at St. Andrews University in the United Kingdom, talks with host Sarah Crespi about her group’s work measuring PCB levels in different killer whale populations and calculating the effect of PCBs on those populations 100 years from now.

These days, thousands of meta-analyses are published every year—many either redundant or contrary to earlier metaworks. Host Sarah Crespi talks to freelance science journalist Jop de Vrieze about ongoing meta-analysis wars in which opposing research teams churn out conflicting metastudies around important public health questions such as links between violent video games and school shootings and the effects of antidepressants. They also talk about what clues to look for when trying to evaluate the quality of a meta-analysis. Sarah also talked with three other contributors to our “Research on Research” special issue. Pierre Azoulay of the Massachusetts Institute of Technology (MIT) in Cambridge, Ben Jones of Northwestern University in Evanston, Illinois, and MIT’s Heidi Williams discuss the evidence for some hoary old scientific home truths. See whether you can guess who originally made these claims and how right or wrong they were: Do scientists make great contributions after age 30?

These days, thousands of meta-analyses are published every year—many either redundant or contrary to earlier metaworks. Host Sarah Crespi talks to freelance science journalist Jop de Vrieze about ongoing meta-analysis wars in which opposing research teams churn out conflicting metastudies around important public health questions such as links between violent video games and school shootings and the effects of antidepressants. They also talk about what clues to look for when trying to evaluate the quality of a meta-analysis. Sarah also talked with three other contributors to our “Research on Research” special issue. Pierre Azoulay of the Massachusetts Institute of Technology (MIT) in Cambridge, Ben Jones of Northwestern University in Evanston, Illinois, and MIT’s Heidi Williams discuss the evidence for some hoary old scientific home truths. See whether you can guess who originally made these claims and how right or wrong they were: Do scientists make great contributions after age 30?

This may seem like a long time ago, but it actually means strawberries have some of the youngest sex chromosomes around. What are the advantages of splitting a species into two sexes? Host Sarah Crespi interviews freelance journalist Carol Cruzan Morton about her story on scientists’ journey to understanding the strawberry’s sexual awakening. In 2016, experimental Zika vaccines were swiftly developed in response to the emergence of serious birth defects in the babies of infected woman. Two years after the height of Zika cases, there’s so little spread of the virus in the Americas that it has stymied vaccine trials. Researchers hope to overcome this hurdle with “human challenge experiments”—vaccinating people, then intentionally infecting them with Zika to see whether they’re protected from the virus. Meagan Cantwell talks with staff writer Jon Cohen about his news story that highlights the risks and rewards of human challenge experiments. This week’s episode was edited by?Podigy.

That’s causing some conservationists to say we need to start thinking about “species triage.” Meagan Cantwell interviews freelance journalist Warren Cornwall about his story on weighing the costs of saving Canada’s endangered caribou and the debate among conservationists on new approaches to conservation. And host Sarah Crespi interviews Hope Michelsen, a staff scientist at Sandia National Laboratories in Livermore, California, about mysterious origins of soot. The black dust has been around since fire itself, but researchers never knew how the high-energy environment of a flame can produce it—until now.

What does this say about peer review? Host Sarah Crespi talks with Staff Writer Kelly Servick about how this project stacks up against similar replication efforts, and whether we can achieve similar results by merely asking people to guess whether a study can be replicated. Podcast producer Meagan Cantwell interviews Emily Brodsky of the University of California, Santa Cruz, about her research report examining why earthquakes occur as far as 10 kilometers from wastewater injection and fracking sites. Emily discusses why the well-established mechanism for human-induced earthquakes doesn’t explain this distance, and how these findings may influence where we place injection wells in the future.

Now, because of their low cost and ease of launching, governments and private companies are looking to expand the range of these “sate-lites” deeper into space. Host Sarah Crespi talks with Deputy News Editor Eric Hand about the mods and missions in store for so-called CubeSats. And our newest podcast producer Meagan Cantwell interviews Quentin Grafton of Australian National University in Canberra and Brad Udall of Colorado State University in Fort Collins about something called the “irrigation efficiency paradox.” As freshwater supplies dry up around the world, policymakers and farmers have been quick to try to make up the difference by improving irrigation, a notorious water waster. It turns out that both human behavior and the difficulty of water measurement are plaguing water conservation efforts in agriculture. For example, when farms find they are using less water, they tend to plant ever-more-water-intensive crops. Now, researchers are trying to get the message out about the behavioral component of this issue and tackle the measurement problem, using cheap remote-sensing technology, but with water scarcity looming ahead, we have to act soon.

But some researchers think letting the public know more about how animals are used in experiments might turn things around. Online News Editor David Grimm joins Sarah Crespi to talk about these efforts. Sarah also talks Ken Wachter of the University of California, Berkeley about his group’s careful analysis of data from all living Italians born 105 or more years before the study. It turns out the risk of dying does not continue to accelerate with age, but actually plateaus around the age of 105. What does this mean for attempts to increase human lifespan?

Now, investigators are using other parts of the genome—such as markers for hair and eye color—to help rule people in and out as suspects. Staff Writer Gretchen Vogel talks with Sarah Crespi about whether science supports this approach and how different countries are dealing with this new type of evidence. Sarah also talks with Jill Fernandes of the University of Queensland in Brisbane, Australia, about her Science Advances paper on a light-based technique for detecting Zika in mosquitoes. Instead of grinding up the bug and extracting Zika DNA, her group shines near-infrared light through the body. Mosquitoes carrying Zika transmit this light differently from uninfected ones. If it’s successful in larger trials, this technique could make large-scale surveillance of infected mosquitoes quicker and less expensive.

And once we know what those genes are—can we help pregnant women feel better? News intern Roni Dengler joins Sarah Crespi to talk about a new study that suggests a protein already flagged for its role in cancer-related nausea may also be behind HG.

Online News Editor David Grimm talks with Sarah Crespi about reporting on this story and what it says about the history of dog domestication. Sarah also interviews physicist Brad Marston of Brown University on surprising findings that bring together planetary science and quantum physics. It turns out that Earth’s rotation and the presence of oceans and atmosphere on its surface mean it can be described as a “topological insulator”—a term usually reserved for quantum phenomena. Insights from the study of these effects at the quantum level may help us understand weather and currents at the planetary level—including insights into climate change and exoplanets.

The problem of navigation has been solved a number of different ways by animals. The desert-dwelling Cataglyphis ant was thought to rely on stride integration, basically counting their steps. But it turns out they have a separate method of keeping track of their whereabouts called “optic flow.” Matthias Wittlinger joins Sarah Crespi to talk about his work with these amazing creatures. ?
