  1. Resolving the dispute over the speed of the expanding universe, and seeking new drug targets for cognitive dysfunction

    7H AGO

    Resolving the dispute over the speed of the expanding universe, and seeking new drug targets for cognitive dysfunction

    First up on the podcast, a new path to calculating the Hubble constant. This value for the universe’s speed of expansion is typically determined in one of two ways, one favored by cosmologists, the other by astronomers. But the resulting values from these methods are consistently different. Staff Writer Daniel Clery joins host Sarah Crespi to discuss how reappearing bursts from deep space, lensed by gravity, could resolve the dispute over the speed of the expanding universe. Next on the show, freelance producer Elah Feder talks with Mauro Costa-Mattioli, principal investigator at Altos Labs’ Institutes of Science, about tuning the “integrated stress response” (ISR) in mouse brains. The ISR pathway turns off much of protein synthesis in cells as a response to stressors such as viral infections or oxygen deprivation. The ISR is overactive in some models of cognitive dysfunction—suggesting the downregulated protein synthesis may hamper brain functions such as memory formation. In his paper, Costa-Mattioli and colleagues show turning on the ISR pathway causes memory problems in mice and turning off the ISR can restore function in mouse models of Alzheimer’s disease and Down syndrome. Although this research was in mice, it suggests cognitive dysfunction associated with many different disorders may involve the ISR—making it a good therapeutic target.

  2. Resurrection plants, Project Hail Mary, and the trouble with sycophantic AI

    MAR 26

    Resurrection plants, Project Hail Mary, and the trouble with sycophantic AI

    First up on the podcast, Deputy News Editor Martin Enserink talks about so-called resurrection plants. These specialized plants can survive up to 95% water loss, whereas most plants struggle when their water levels dip below 60%. We also hear from Jill Farrant, a professor of molecular and cell biology at the University of Cape Town, about her work dissecting the desiccation survival pathways in resurrection plants and how they might be repurposed to protect crop plants from drought. Next on the show, we’ve all heard of chatbots praising their users for asking the most basic of questions. This bias toward sycophancy extends beyond pleasantries into relationship advice the artificial intelligence (AI) doles out to users. Myra Cheng, a Ph.D. candidate in computer science at Stanford University, joins the show to talk about how this tendency for AIs to be agreeable can lead users to have more confidence in their opinions, to the detriment of their relationships with others. Warning, this last segment contains spoilers for the movie and book Project Hail Mary by Andy Weir. If you’ve seen the movie or don’t mind a bit of extra context, you will hear an analysis of planetary science in the film with astrophysicist and associate curator at the American Museum of Natural History, Jacqueline Faherty.

  3. Rethinking the peopling of the Americas, and the best ways to get groundwater back

    Rethinking the peopling of the Americas, and the best ways to get groundwater back

    First up on the podcast, we discuss a finding that’s likely to reignite debate over how humans first spread through the Americas. In the late 1990s, a site in southern Chile called Monte Verde forced archaeologists to adjust their views of the peopling of South America because it dated to about 14,500 years before present, which challenged the prevailing idea of when human inhabitants appeared on the continent. Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss new results published in Science that suggest Monte Verde is nowhere near that old. See the paper and related commentary. Next on the show, we talk about groundwater, a vital source of water for both drinking and agriculture that’s often overused and depleted. Producer Meagan Cantwell talks with Scott Jasechko, a professor of water resources with the University of California, Santa Barbara’s Bren School of Environmental Science & Management, about the many different approaches to improving groundwater supplies and what has worked where, which he reviews in this week’s issue of Science.

  4. What Alaska’s eroding coastline says about Earth’s future, and how Yellowstone ravens use their smarts to find wolf kills

    MAR 12

    What Alaska’s eroding coastline says about Earth’s future, and how Yellowstone ravens use their smarts to find wolf kills

    First up on the podcast, freelance journalist Evan Howell traveled to Cape Blossom, Alaska, where the receding coastline has revealed an ancient trove of glacial ice that may have survived for 350,000 years—making it the oldest ice in the Northern Hemisphere. Now researchers just need to figure out how to date it. Next on the show, tracking wolves and ravens in Yellowstone National Park shows the birds don’t follow the wolves in hope of a meal, but instead remember and revisit frequent wolf kill sites. Matthias-Claudio Loretto, assistant professor in the Research Institute of Wildlife Ecology at the University of Veterinary Medicine Vienna, discusses how this might change the way we think about scavengers’ strategies for finding their ephemeral food sources.  Finally, Claire Bedbrook, the Helen Hay Whitney and Wu Tsai neuroscience postdoctoral fellow at Stanford University, discusses her work tracking African turquoise killifish over their life span. By capturing behaviors over the course of the fish’s entire lives, her team was able to observe behaviors that could be used to predict whether a fish would live a short or long life.

  5. An alleged nuclear blast may reignite weapons testing, and who owns the Moon

    MAR 5

    An alleged nuclear blast may reignite weapons testing, and who owns the Moon

    First up on the podcast, a peek into the roiling seas of U.S. science policy. ScienceInsider Editor Jocelyn Kaiser talks about shifting leadership at the National Science Foundation and the Centers for Disease Control and Prevention as well as a dip in funding rates by the National Institutes of Health. Staff Writer Robert F. Service covers proposed restrictions on access by international researchers and students to the National Institute of Standards and Technology. Contributing Correspondent Warren Cornwall talks about the Department of Energy’s rush to loosen radiation exposure standards. Senior International Correspondent Richard Stone discusses why an accusation of nuclear weapons testing in China could spark a new round of weapons testing in the United States and Russia. Next on the show, this year’s children’s book roundup features everything from a look at space law to a clever wartime spider farmer. Senior Editor Valerie Thompson joins host Sarah Crespi to discuss the books and the reviews of them, written by Science staffers (and sometimes their kids).

    Tropical birds’ ‘silent spring,’ and mapping people’s brains during surgery

    First up on the podcast, producer Meagan Cantwell talks to Contributing Correspondent Warren Cornwall about his visit to Brazil, where he observed firsthand what it takes for researchers to understand why bird populations in the Amazon and beyond are shrinking. Next on the show, Raouf Belkhir, an M.D.-Ph.D. student at the University of Pittsburgh School of Medicine and Carnegie Mellon University, joins host Sarah Crespi to discuss his Science Advances paper on a newly refined way to map awake patients’ brains during neurosurgery.

    Matching sounds to shapes, and stories from the AAAS annual meeting

    First up on the podcast, Newsletter Editor Christie Wilcox, Associate Online News Editor Michael Greshko, and intern Perri Thaler share their experiences from the AAAS annual meeting in Phoenix. Christie recorded on location with David Rand regarding his prize-winning Science paper on using a large language model to combat conspiracy theories. Check out the live version of his team’s Debunk Bot. Michael chats with host Sarah Crespi about the foggy outlook of science in the United States as funding levels and graduate positions decline, and the bright sunshine of young students presenting science posters. And finally, Perri shares her reporting on OpenAI’s contribution to theoretical physics announced at the meeting. Next on the show, we hear about the “bouba-kiki” effect—the tendency for people, no matter their language, to associate round shapes with the nonword bouba and spiky shapes with the nonword kiki. Maria Loconsole, a postdoctoral researcher in the Comparative Cognition Lab at the University of Padova, joins the podcast to discuss why her team looked for this effect in freshly hatched chickens. It turns out these baby birds also make these associations, which suggests the effect has less to do with language and more to do with how vertebrate brains are set up to experience the world.

    Building better working dogs, and watching a black hole form

    First up on the podcast, more than half of all dogs going through service animal training don’t make it to graduation. Producer Kevin McLean journeys with Online News Editor David Grimm to Canine Companions, one of the biggest organizations in the United States for training working dogs. At the facility, they meet puppies in preparation and learn about the behavioral testing and genetics that could be used to improve service animal schooling. Also appearing in this segment: Emily Bray, assistant professor in the College of Veterinary Medicine at the University of Arizona Brenda Kennedy, chief veterinary and research officer at Canine Companions Next on the show, Kishalay De, assistant professor at Columbia University and associate research scientist at the Flatiron Institute, talks about observing the birth of a stellar black hole in the nearby Andromeda galaxy. He recounts how his team looked for this elusive event and describes what we can learn from observing it in the decades to come. This week’s episode was produced with help from Podigy.
