  • GLP-1 targets beyond obesity, and misusing brain data

    GLP-1 targets beyond obesity, and misusing brain data
    Nov 5 2026
    First up on the podcast, people are buying consumer-grade brain wave detectors ostensibly to help with sleep, concentration, and meditation. But as freelance investigative journalist Jonathan Moens describes, companies are getting more than the price of the devices in the exchange—including training data for artificial intelligence models—in many cases without the consent of the user. Next on the show, we delve into the many uses for glucagonlike peptide-1 (GLP-1) agonist drugs beyond reducing obesity. Host Sarah Crespi talks with one of the special issue editors, Yevgeniya Nusinovich, senior editor at Science, about their potential for everything from improving cognition to combating cancer. Then we hear from Nora Volkow, director of the National Institute on Drug Abuse at the National Institutes of Health, about hopes for using GLP-1 therapies to address addiction to a range of substances.

  • Destroying forever chemicals, hyperlocal pollution sensing, and an experiment in queer parenthood

    Destroying forever chemicals, hyperlocal pollution sensing, and an experiment in queer parenthood
    Oct 29 2026
    First up on the podcast, thousands of tons of per- and polyfluoroalkyl substances (PFAS) have been released into the environment. It’s not always that difficult to round them up, but what to do next has been a tougher call. Until now, the default has been to burn PFAS—but that has been shown in some cases to release smaller PFAS back into the environment. Freelance science journalist Mark Peplow joins host Sarah Crespi to talk over recent technological improvements in destroying these forever chemicals and how feasible it is to deploy them. Next on the show, News Intern Julia Vaz talks with Chirag Manchanda, a postdoctoral researcher at Stanford University, about his Science Advances paper on new ways to analyze the sources of urban air pollution. Finally, the last in our six-part series on scientific biographies. Host Angela Saini talks with biologist Joe Osmundson about his new memoir, Spawning Season: An Experiment in Queer Parenthood.

  • Birds make decisions faster than we do, rewriting DNA’s history, and combining science and poetry

    Birds make decisions faster than we do, rewriting DNA’s history, and combining science and poetry
    Oct 22 2026
    First up on the podcast, News Editor Tim Appenzeller joins host Sarah Crespi to talk about an x-ray image that is upsetting the narrative of DNA’s discovery as told by James Watson. A newly resurfaced photo taken by Rosalind Franklin—photo 49—shows she was aware of the helical structure of DNA and explains why her published image—photo 51—does not have indications of her understanding of its shape. Next on the show, producer Elah Feder chats with Andreas Nieder, professor of animal physiology and director of the Institute for Neurobiology at the University of Tübingen, about the high speed of bird cognition. It turns out in experimental settings carrion crows make decisions twice as fast as primates. The conversation delves into what could make avian brains ultrafast and the evolutionary advantages of speedy thinking. Last up this week, poets and scientists get together in books and in real life. Phil Levin and David Hassler discuss their collaboration on a joint effort to create a poetry anthology and a scientific report on the state of nature. They explain how they see science and poetry are connected, and how their ideas will be put into action at an upcoming conference on poetry and science in November. Also in this segment, Lara Volski reads her poem “The Monarch Bear.” People in this segment Phil Levin, professor in sustainability science and director of the School of Marine and Environmental Affairs at the University of Washington (UW) David Hassler, executive director of the Wick Poetry Center at Kent State University Lara Volski, Ph.D. candidate in the People and Wildlife Lab at UW Works mentioned The Nature of Our Times: Poems on America’s Lands, Waters, Wildlife, and Other Natural Wonders The Nature Record Conference details Poet and science gathering at Kent State This week’s episode was produced with help from Podigy.

  • Cheese history, redating the Inca empire, and the source of the breath’s rhythm

    Cheese history, redating the Inca empire, and the source of the breath’s rhythm
    Oct 15 2026
    First up on the podcast, producer Meagan Cantwell and Newsletter Editor Christie Wilcox discuss a few stories from ScienceAdviser, including why Nazi Germany was unlikely to ever make an atomic bomb, a gene that might prevent gray hairs, and 140 years of cheese history from a Swiss basement. Next on the show, Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss how archaeologists are revisiting the standard Inca chronology as radiocarbon dates mix up the timeline for the empire’s inception and growth. Last up this week, the neural basis of our breath’s rhythm. Nicholas Bush, a staff research scientist at Epsilon, talks about using modern neuronal recording techniques and computing to describe the generation of rhythmic breathing.

  • A moon heist, lava fountains, and predicting doomsday

    A moon heist, lava fountains, and predicting doomsday
    Oct 8 2026
    First up on the podcast, freelance science journalist Robin George Andrews describes Japan’s upcoming Martian Moons eXploration mission that will nab a sample from the surface of Mars’s moon Phobos. The material, due back to Earth in 2031, could reveal the origins of this mysterious moon, the past habitability of Mars, or even hints of life itself. Next on the show, Hawaii’s Kilauea volcano started to periodically spew tall fountains of lava in December 2024. Researchers and the public tuned in to watch more than 50 fountaining events steaming live online. Ashton Flinders, a research geophysicist at the U.S. Geological Survey’s Hawaiian Volcano Observatory, joins host Sarah Crespi to talk about how observations from the cameras plus geochemical, geophysical, and geologic monitoring revealed a predictable pattern in these usually rare events. Last up this week, Javier Birchenall, professor of economics at the University of California, Santa Barbara, discusses predictions of world-ending crises—starting with a prediction published in a Science paper in 1960 that suggested Earth’s population would reach a singularity on 13 November 2026. We are still here and the global population is headed for a decline. What happened to the singularity and what else are we not predicting very well?

  • Stimulating the brain for women’s health, and the long-term implications of menopausal symptoms

    Stimulating the brain for women’s health, and the long-term implications of menopausal symptoms
    Oct 1 2026
    First up on the podcast, Staff Writer Jennie Erin Smith joins host Sarah Crespi to talk about new research on how noninvasive technologies such as transcranial magnetic stimulation are being used in the context of women’s health to tackle everything from postpartum depression to menstrual pain and fertility issues. Next on the show, we talk with Liisa Galea, Treliving family chair in women’s mental health and professor in the department of psychiatry at the University of Toronto. In a review in this week’s special issue on women’s health, Galea discusses the state of research on hormone therapy during perimenopause and the links between menopausal symptoms and long-term concerns such as dementia and cardiovascular disease.
