it Sending flocks of tiny satellites out past Earth orbit and solving the irrigation efficiency paradox By traffic.omny.fm Published On :: Thu, 23 Aug 2018 14:00:00 -0400 Small satellites—about the size of a briefcase—have been hitching rides on rockets to lower Earth orbit for decades. 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.

it <i>Science</i> and <i>Nature</i> get their social science studies replicated—or not, the mechanisms behind human-induced earthquakes, and the taboo of claiming causality in science By traffic.omny.fm Published On :: Thu, 30 Aug 2018 14:30:00 -0400 A new project out of the Center for Open Science in Charlottesville, Virginia, found that of all the experimental social science papers published in Science and Nature from 2010–15, 62% successfully replicated, even when larger sample sizes were used. 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. In this month’s book podcast, Jen Golbeck interviews Judea Pearl and Dana McKenzie, authors of The Book of Why: The New Science of Cause and Effect. They propose that researchers have for too long shied away from claiming causality and provide a road map for bringing cause and effect back into science. This week’s episode was edited by Podigy.

it Should we prioritize which endangered species to save, and why were chemists baffled by soot for so long? By traffic.omny.fm Published On :: Thu, 06 Sep 2018 14:45:00 -0400 We are in the middle of what some scientists are calling the sixth mass extinction and not all at-risk species can be saved. 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. Michelsen walks Sarah through the radical chemistry of soot formation—including its formation of free radicals—and discusses soot’s many roles in industry, the environment, and even interstellar space. Check out this useful graphic describing the soot inception process in the related commentary article. This week’s episode was edited by Podigy.

it The youngest sex chromosomes on the block, and how to test a Zika vaccine without Zika cases By traffic.omny.fm Published On :: Thu, 13 Sep 2018 15:00:00 -0400 Strawberries had both male and female parts, like most plants, until several million years ago. 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.

it The future of PCB-laden orca whales, and doing genomics work with Indigenous people By traffic.omny.fm Published On :: Thu, 27 Sep 2018 14:45:00 -0400 Science has often treated Indigenous people as resources for research—especially when it comes to genomics. 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. In this month’s book segment, Jen Golbeck interviews Damon Centola about his book How Behavior Spreads: The Science of Complex Contagions.

it What we can learn from a cluster of people with an inherited intellectual disability, and questioning how sustainable green lawns are in dry places By traffic.omny.fm Published On :: Thu, 11 Oct 2018 14:45:00 -0400 A small isolated town in Colombia is home to a large cluster of people with fragile X syndrome—a genetic disorder that leads to intellectual disability, physical abnormalities, and sometimes autism. Spectrum staff reporter Hannah Furfaro joins host Sarah Crespi to discuss the history of fragile X in the town of Ricaurte and the future of the people who live there. Also this week, we talk about greening up grass. Lawns of green grass pervade urban areas all around the world, regardless of climate, but the cost of maintaining them may outweigh their benefits. Host Meagan Cantwell talks with Maria Ignatieva of The University of Western Australia in Perth and the Swedish University of Agricultural Sciences in Uppsala about how lawns can be transformed to contribute to a more sustainable future.

it Children sue the U.S. government over climate change, and how mice inherit their gut microbes By traffic.omny.fm Published On :: Thu, 25 Oct 2018 14:30:00 -0400 A group of children is suing the U.S. government—claiming their rights to life, liberty, and property are under threat from climate change thanks to government policies that have encouraged the use and extraction of fossil fuels. Host Meagan Cantwell interviews news writer Julia Rosen on the ins and outs of the suit and what it could mean if the kids win the day. Also this week, host Sarah Crespi talks with Andrew Moeller of Cornell University about his work tracing the gut microbes inherited through 10 generations of mice. It turns out the fidelity is quite high—you can still tell mice lineages apart by their gut microbes after 10 generations. And horizontally transmitted microbes, those that jump from one mouse line to another through exposure to common spaces or handlers, were more likely than inherited bacteria to be pathogenic and were often linked to illnesses in people.

it How far out we can predict the weather, and an ocean robot that monitors food webs By traffic.omny.fm Published On :: Thu, 14 Feb 2019 14:00:00 -0500 The app on your phone tells you the weather for the next 10 days—that’s the furthest forecasters have ever been able to predict. In fact, every decade for the past hundred years, a day has been added to the total forecast length. But we may be approaching a limit—thanks to chaos inherent in the atmosphere. Staff writer Paul Voosen joins host Sarah Crespi to talk about how researchers have determined that we will only be adding about 5 more days to our weather prediction apps. Also this week, host Meagan Cantwell interviews Trygve Fossum from the Norwegian University of Science and Technology in Trondheim about his article in Science Robotics on an underwater autonomous vehicle designed to sample phytoplankton off the coast of Norway. The device will help researchers form a better picture of the base of many food webs and with continued monitoring, researchers hope to better understand key processes in the ocean such as nutrient, carbon, and energy cycling.

it Measuring earthquake damage with cellphone sensors and determining the height of the ancient Tibetan Plateau By traffic.omny.fm Published On :: Thu, 28 Feb 2019 14:45:00 -0500 In the wake of a devastating earthquake, assessing the extent of damage to infrastructure is time consuming—now, a cheap sensor system based on the accelerometers in cellphones could expedite this process. Host Sarah Crespi talks with Contributing Correspondent Lizzie Wade about how these sensor systems work and how they might assist communities after an earthquake. In another Earth-shaking study, scientists have downgraded the height of the ancient Tibetan Plateau. Most reconstructions estimate that the “rooftop of the world” reached its current height of 4500 meters about 40 million years ago, but a new study suggests it was a mere 3000 meters high during this period. Host Meagan Cantwell speaks with Svetlana Botsyun, a postdoctoral researcher at Tübingen University in Germany, about her team’s new approach to studying paleoelevation, and how a shorter Tibetan Plateau would have impacted the surrounding area’s climate.

it Vacuuming potato-size nodules of valuable metals in the deep sea, and an expedition to an asteroid 290 million kilometers away By traffic.omny.fm Published On :: Thu, 21 Mar 2019 14:45:00 -0400 Pirate’s gold may not be that far off, as there are valuable metals embedded in potato-size nodules thousands of meters down in the depths of the ocean. 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.

it Nonstick chemicals that stick around and detecting ear infections with smartphones By traffic.omny.fm Published On :: Thu, 16 May 2019 14:00:00 -0400 The groundwater of Rockford, Michigan, is contaminated by per- and polyfluoroalkyl substances, chemicals found in everything from nonstick pans to dental floss to—in the case of Rockford—waterproofing agents from a shoe factory that shut down in 2009. Science journalist Sara Talpos talks with host Meagan Cantwell about how locals found the potentially health-harming chemicals in their water, and how contamination from nonstick chemicals isn’t limited to Michigan. Also this week, host Sarah Crespi talks with Shyamnath Gollakota of the University of Washington in Seattle about his work diagnosing ear infections with smartphones. With the right app and a small paper cone, it turns out that your phone can listen for excess fluid in the ear by bouncing quiet clicks from the speaker off the eardrum. Clinical testing shows the setup is simple to use and can help parents and doctors check children for this common infection. This week’s episode was edited by Podigy.

it The limits on human endurance, and a new type of LED By traffic.omny.fm Published On :: Thu, 06 Jun 2019 14:45:00 -0400 Cheap and easy to make, perovskite minerals have become the wonder material of solar energy. Now, scientists are turning from using perovskites to capture light to using them to emit it. Staff Writer Robert Service joins host Sarah Crespi to talk about using these minerals in all kinds of light-emitting diodes, from cellphones to flat screen TVs. Read the related paper in Science Advances. Also this week, Sarah talks with Caitlin Thurber, a biologist at Nassau Community College in Garden City, New York, about a hard limit on human endurance. Her group used data from transcontinental racers—who ran 957 kilometers over the course of 20 weeks—and found that after about 100 days, their metabolism settled in at about 2.5 times the baseline rate, suggesting a hard limit on human endurance at long timescales. Earlier studies based on the 23-day Tour de France found much higher levels of energy expenditure, in the four- to five-times-baseline range.

it Better hurricane forecasts and spotting salts on Jupiter’s moon Europa By traffic.omny.fm Published On :: Thu, 13 Jun 2019 14:45:00 -0400 We’ve all seen images or animations of hurricanes that color code the wind speeds inside the whirling mass—but it turns out we can do a better job measuring these winds and, as a result, better predict the path of the storm. Staff Writer Paul Voosen talks with host Sarah Crespi about how a microsatellite-based project for measuring hurricane wind speeds is showing signs of success—despite unexpected obstacles from the U.S. military’s tweaking of GPS signals. Also this week, Sarah talks with graduate student Samantha Trumbo, a Ph.D. candidate in planetary science at the California Institute of Technology in Pasadena, about spotting chloride salts on the surface of Jupiter’s moon Europa.

it Creating chimeras for organ transplants and how bats switch between their eyes and ears on the wing By traffic.omny.fm Published On :: Thu, 27 Jun 2019 14:45:00 -0400 Researchers have been making animal embryos from two different species, so-called “chimeras,” for years, by introducing stem cells from one species into a very early embryo of another species. The ultimate goal is to coax the foreign cells into forming an organ for transplantation. But questions abound: Can evolutionarily distant animals, like pigs and humans, be mixed together to produce such organs? Or could species closely related to us, like chimps and macaques, stand in for tests with human cells? Staff Writer Kelly Servick joins host Sarah Crespi to discuss the research, the regulations, and the growing ethical debate. Also this week, Sarah talks with Yossi Yovel of the School of Zoology and the Sagol School of Neuroscience at Tel Aviv University in Israel about his work on sensory integration in bats. Writing in Science Advances, he and his colleagues show through several clever experiments when bats switch between echolocation and vision. Yossi and Sarah discuss how these trade-offs in bats can inform larger questions about our own perception. For our monthly books segment, Science books editor Valerie Thompson talks with Lucy Jones of the Seismological Laboratory at the California Institute of Technology in Pasadena about a song she created, based on 130 years of temperature data, for an instrument called the “viola de gamba.” Read more on the Books et al. blog.

it Converting carbon dioxide into gasoline, and ‘autofocal’ glasses with lenses that change shape on the fly By traffic.omny.fm Published On :: Thu, 04 Jul 2019 14:00:00 -0400 Chemists have long known how to convert carbon dioxide into fuels—but up until now, such processes have been too expensive for commercial use. Staff Writer Robert Service talks with host Sarah Crespi about using new filters and catalysts to close the gap between air-derived and fossil-derived gasoline. Also this week, host Sarah Crespi talks with Nitish Padmanaban of Stanford University in Palo Alto, California, about replacing bifocals with “autofocals.” These auto-focusing glasses track your eye position and measure the distance to the visual target before adjusting the thickness of their liquid lenses. The prototype glasses have an onboard camera and batteries that make them particularly bulky; however, they still outperformed progressive lenses in tests of focus speed and acuity.

it Can we inherit trauma from our ancestors, and the secret to dark liquid dances By traffic.omny.fm Published On :: Thu, 18 Jul 2019 14:30:00 -0400 Can we inherit trauma from our ancestors? Studies of behavior and biomarkers have suggested the stress of harsh conditions or family separations can be passed down, even beyond one’s children. Journalist Andrew Curry joins host Sarah Crespi to discuss a possible mechanism for this mode of inheritance and mouse studies that suggest possible ways to reverse the effects. Spiky, pulsating ferrofluids are perpetual YouTube stars. The secret to these dark liquid dances is the manipulation of magnetic nanoparticles in the liquid by external magnets. But when those outside forces are removed, the dance ends. Now, researchers writing in Science have created permanently magnetic fluids that respond to other magnets, electricity, and pH by changing shape, moving, and—yes—probably even dancing. Sarah Crespi talks to Thomas Russell of the University of Massachusetts in Amherst about the about the applications of these squishy, responsive magnets. This week’s episode was edited by Podigy.

it Next-generation cellphone signals could interfere with weather forecasts, and monitoring smoke from wildfires to model nuclear winter By traffic.omny.fm Published On :: Thu, 08 Aug 2019 14:45:00 -0400 In recent months, telecommunications companies in the United States have purchased a new part of the spectrum for use in 5G cellphone networks. Weather forecasters are concerned that these powerful signals could swamp out weaker signals from water vapor—which are in a nearby band and important for weather prediction. Freelance science writer Gabriel Popkin joins host Sarah Crespi to talk about the possible impact of cellphone signals on weather forecasting and some suggested regulations. In other weather news this week, Sarah talks with Pengfei Yu, a professor at Jinan University in Guangzhou, China, about his group’s work using a huge smoke plume from the 2017 wildfires in western Canada as a model for smoke from nuclear bombs. They found the wildfire smoke lofted itself 23 kilometers into the stratosphere, spread across the Northern Hemisphere, and took 8 months to dissipate, which line up with models of nuclear winter and suggests these fires can help predict the results of a nuclear war.

International News Editor Martin Enserink visited the site with researchers studying chronic mountain sickness—when the body makes excess red blood cells in an effort to cope with oxygen deprivation—in these extreme conditions. Martin talks with host Sarah Crespi about how understanding why this illness occurs in some people and not others could help the residents of La Rinconada and the 140 million people worldwide living above 2500 meters. Read the whole special issue on mountains. Sarah also talks with Annika Stefanie Reinhold about her work at the Bernstein Center for Computational Neuroscience in Berlin training rats to play hide and seek. Surprisingly, rats learned the game easily and were even able to switch roles—sometimes playing as the seeker, other times the hider. Annika talks with Sarah about why studying play behavior in animals is important for understanding the connections between play and learning in both rats and humans.

it Trying to find the mind in the brain, and why adults are always criticizing ‘kids these days’ By traffic.omny.fm Published On :: Thu, 17 Oct 2019 14:45:00 -0400 We don’t know where consciousness comes from. And we don’t know whether animals have it, or whether we can detect it in patients in comas. Do neuroscientists even know where to look? A new competition aims to narrow down the bewildering number of theories of consciousness and get closer to finding its biological signs by pitting different theories against each other in experimental settings. Freelance journalist Sara Reardon talks with host Sarah Crespi about how the competition will work. In our second segment, we talk about how we think about children. For thousands of years, adults have complained about their lack of respect, intelligence, and tendency to distraction, compared with previous generations. A new study out this week in Science Advances suggests our own biased childhood memories might be at fault. Sarah Crespi talks with John Protzko of the University of California, Santa Barbara, about how terrible people thought kids were in 3800 B.C.E. and whether understanding those biases might change how people view Generation Z today.

it A worldwide worm survey, and racial bias in a health care algorithm By traffic.omny.fm Published On :: Thu, 24 Oct 2019 14:45:00 -0400 Earthworms are easy … to find. But despite their prevalence and importance to ecosystems around the world, there hasn’t been a comprehensive survey of earthworm diversity or population size. This week in Science, Helen Philips, a postdoctoral fellow at the German Centre for Integrative Biodiversity Research and the Institute of Biology at Leipzig University, and colleagues published the results of their worldwide earthworm study, composed of data sets from many worm researchers around the globe. Host Sarah Crespi gets the lowdown from Philips on earthworm myths, collaborating with worm researchers, and links between worm populations and climate. Read a related commentary here. Sarah also talks with Ziad Obermeyer, a professor in the School of Public Health at the University of California, Berkeley, about dissecting out bias in an algorithm used by health care systems in the United States to recommend patients for additional health services. With unusual access to a proprietary algorithm, inputs, and outputs, Obermeyer and his colleagues found that the low amount of health care dollars spent on black patients in the past caused the algorithm to underestimate their risk for poor health in the future. Obermeyer and Sarah discuss how this happened and remedies that are already in progress. Read a related commentary here.

it Building a landslide observatory, and the universality of music By traffic.omny.fm Published On :: Thu, 21 Nov 2019 14:30:00 -0500 You may have seen the aftermath of a landslide, driving along a twisty mountain road—a scattering of rocks and scree impinging on the pavement. 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. In a second rocking segment, Sarah also talks with Manvir Singh about the universality of music. His team asked the big questions in a Science paper out this week: Do all societies make music? What are the common elements that can be picked out from songs worldwide? Sarah and Manvir listen to songs and talk about what love ballads and lullabies have in common, regardless of their culture of origin. Explore the music database.

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 Science’s leading role in the restoration of Notre Dame, and the surprising biology behind how our body develops its tough skin By traffic.omny.fm Published On :: Thu, 12 Mar 2020 14:00:00 -0400 On this week’s show, freelance writer Christa Lesté-Lasserre talks with host Sarah Crespi about the scientists working on the restoration of Notre Dame, from testing the changing weight of wet limestone, to how to remove lead contamination from four-story stained glass windows. As the emergency phase of work winds down, scientists are also starting to use the lull in tourist activity to investigate the mysteries of the cathedral’s construction. Also this week, Felipe Quiroz, an assistant professor in the biomedical engineering department at the Georgia Institute of Technology and Emory University, talks with Sarah about his paper on the cellular mechanism of liquid-liquid phase separation in the formation of the tough outer layer of the skin. Liquid-liquid phase separation is when two liquids “demix,” or separate, like oil and water. In cells, this process created membraneless organelles that are just now starting to be understood. In this work, Quiroz and colleagues create a sensor for phase separation in the cell that works in living tissue, and show how phase separation is tied to the formation of the outer layers of skin in mice.
