Statisticians fight bad numbers used in medical murder trials, and the state of allergy science First up on this week’s show, we have a piece on accusations of medical murder. Contributing Correspondent Cathleen O’Grady joins host Sarah Crespi to discuss her story on how statisticians are weighing in on cases where nurses and doctors are convicted of murdering patients based on bad statistics. This segment was produced by Kevin McLean with sound design by James Rowlands. Also on this week’s show: Allergies are on the rise and this increase is linked with climate change. Sarah speaks with Kari Nadeau, Naddisy Foundation endowed professor of medicine and pediatrics at Stanford University, about her review in Science Translational Medicine on the status of allergy science, and how recommendations have changed from when to give children peanuts to opting for sublingual exposure therapy.

Keeping an eye on the largest hydroelectric project in the Amazon basin, and helping patients with deletions in their mitochondrial DNA We are starting off the new year with producer Kevin McLean and freelance science journalist Sofia Moutinho. They discuss a controversial dam in the Brazilian Amazon and how Indigenous peoples and researchers are trying to monitor its impact. Then, host Sarah Crespi speaks with Elad Jacoby, an expert in pediatric hematology and oncology at the Sheba Medical Center and Tel Aviv University, about the many wonders of mitochondria. In a recent Science Translational Medicine paper, his team took advantage of the fact that mitochondria are almost exclusively inherited from our mothers to transfer mothers’ mitochondria into their children as treatment for mitochondrial genome deletions.

On this week’s show: A medieval German cemetery yields clues to Jewish migrations in Europe, and supercomputers help researchers estimate magma under Yellowstone First up this week on the podcast, we explore the genetic history of Jewish people in Europe. Contributing Correspondent Andrew Curry talks with host Sarah Crespi about researchers working with rabbis and the local Jewish community to apply new techniques to respectfully study remains in a medieval Jewish cemetery in Germany. We also have a story on how much magma has accumulated inside Yellowstone National Park’s supervolcano. Producer Meagan Cantwell talks with Ross Maguire, an assistant professor in the geology department at University of Illinois, Urbana-Champaign, about using supercomputers to get a clearer picture of the volcanic system’s subsurface. Although this new study shows more magma than previous estimates, it’s still not nearly enough for an eruption anytime soon. This week’s episode was produced with help from Podigy.

On this week’s show: Meta’s algorithm tackles both language and strategy in a board game, and measuring how much water people use on a daily basis First up this week on the podcast, artificial intelligence (AI) wins at the game Diplomacy. Freelance science journalist Matthew Hutson joins host Sarah Crespi to talk about the advances needed for an AI to win a game that requires cooperation and trust between human and AI players. Next, we hear about how much water people need to stay hydrated. It’s not the eight glasses a day recommendation we’ve heard so much about. Herman Pontzer, a professor in Duke University’s Department of Evolutionary Anthropology and the Duke Global Health Institute, talks about a study that involved recording water turnover from 5000 people around the world. It turns out daily water needs vary from person to person and place to place. This week’s episode was produced with help from Podigy.

On this week’s show: The potentially harmful effects of prehistoric ivory on present-day elephants, and replacing polymers in electronics with fungal tissue First up this week on the podcast, we hear about the effect of mammoth and mastodon ivory on the illegal elephant ivory trade. Online News Editor Michael Price joins host Sarah Crespi to discuss how as melting permafrost has uncovered fossilized ivory from these extinct creatures, more has entered the ivory trade. The question is: Does the availability of this type of ivory reduce the demand for ivory from elephants, or does it endanger them more? Next, making electronics greener with fungus with Doris Danninger, a Ph.D. student in the Soft Matter Physics Division at the Institute of Experimental Physics at Johannes Kepler University, Linz. Doris and Sarah discuss the feasibility of replacing the bulky backing of chips and the casing of batteries with sheets of fungal tissue to make flexible, renewable, biodegradable electronics.

News Intern Zack Savitsky and host Sarah Crespi discuss the work of ethicists, philosophers, and Vonnegut scholars on his influence on the ethics and practice of science. Researchers featured in this segment: Peter-Paul Verbeek, a philosopher of science and technology at the University of Amsterdam and chair of the World Commission on the Ethics of Scientific Knowledge and Technology David Koepsell, a philosopher of science and technology at Texas A&M University, College Station Christina Jarvis, a Vonnegut scholar at the State University of New York, Fredonia, and author of the new book Lucky Mud & Other Foma: A Field Guide to Kurt Vonnegut’s Environmentalism and Planetary Citizenship Sheila Jasanoff, a science studies scholar at Harvard University Next, producer Kevin McLean discusses the connection between fishing pressure and extinction risk for large predatory fish such as tunas and sharks. He’s joined by Maria José Juan Jordá, a postdoc at the Spanish Institute for Oceanography, to learn what a new continuous Red List Index using the past 70 years of fisheries data can tell us about the effectiveness and limits of fishing regulations. Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Joseph Hyser, assistant professor in the Department of Molecular Virology and Microbiology at Baylor College of Medicine about his use of wide-field fluorescence live cell microscopy to track intercellular calcium waves created following rotavirus infection.
