  • 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.

  • Studying the changing of AI language inside swarms, how orangutans learn to forage, and an astrophysicist talks about loss

    Studying the changing of AI language inside swarms, how orangutans learn to forage, and an astrophysicist talks about loss
    Sep 24 2026
    First up on the podcast, Staff Reporter Tom Howarth joins host Sarah Crespi to talk about the language artificial intelligence agents evolve inside their swarms. Next on the show, producer Elah Feder talks with Revathe Thillaikumar,  a behavioral ecologist and postdoctoral fellow at the Max Planck Institute of Animal Behavior. The two discuss the value of social learning as baby orangutans learn to find their own food over the longest dependency period of any animal, except humans. Finally, from our series on scientific autobiographies, books host Angela Saini talks with astrophysicist Sara Seager about the moving account of life after losing her husband in her book, The Smallest Lights in the Universe.

  • Can ‘assisted migration’ save forests? And the role of philosophy in science

    Can ‘assisted migration’ save forests? And the role of philosophy in science
    Sep 17 2026
    First up on the podcast, as the planet warms and forests burn, can we replant them with new trees that will thrive in the decades ahead? Associate Editor Katie Langin joins host Sarah Crespi to discuss research into “assisted migration” for replenishing forests after wildfires. Next on the show, Susana Monsó, an associate professor in the Department of Logic, History and Philosophy of Science at the Spanish National University of Distance Education, shares her latest Expert Voices column. She discusses how philosophy can play a role in the scientific process—from defining terms to formulating questions. This week’s episode was produced with help from Podigy.

  • Psychoactive substances helped spur Andean civilization, and breaking barriers to education

    Psychoactive substances helped spur Andean civilization, and breaking barriers to education
    Sep 10 2026
    First up on the podcast, producer Meagan Cantwell and freelance journalist Andrew Lawler discuss how psychoactive drugs might have shaped culture in pre-Inca Andean societies. They chat about how technical advances and an increasingly open research environment have allowed scientists to detect traces of substances such as vilca, which contains dimethyl­tryptamine, the psychoactive compound also found in ayahuasca. Next on the show, host Sarah Crespi is joined by Noam Angrist, academic director of the What Works Hub for Global Education at the University of Oxford’s Blavatnik School of Government. Angrist wrote a Policy Forum piece on the need to move on from small, controlled trials of education interventions to better address educational needs in lower and middle-income countries. To move forward, he explains, we need to learn how to make sure these interventions work at scale and that governments can readily implement them.

  • Sex-reversing frogs, and Europe’s rising rates of a deadly tick-borne disease

    Sex-reversing frogs, and Europe’s rising rates of a deadly tick-borne disease
    Sep 3 2026
    First up on the podcast, Senior International Correspondent Richard Stone joins host Sarah Crespi to discuss how climate is pushing the disease-carrying tick Hyalomma marginatum out of its comfort zone. Stone reports from Kosovo, where the tick has long been endemic, on how surveillance can uncover hidden circulation—and help countries prepare before human cases appear. Next on the show, researchers have long known ambient temperatures cause some species of amphibians to reverse sex. In the case of the agile frog (Rana dalmatina), genetically female frogs take on male characteristics at elevated temperatures—including the ability to sire offspring. Veronika Bókony, an evolutionary ecologist at the Center for Agricultural Science in Hungary, examined what happens to the offspring of sex-reversed agile frogs, which will probably make up more of the species’ population as the planet warms.

  • Making drugs in space, the man who fed India, and what narwhals can teach us about changing seas

    Making drugs in space, the man who fed India, and what narwhals can teach us about changing seas
    Aug 27 2026
    First up on the podcast, will it ever make economic sense to produce drugs and biomedical supplies in space? Associate Online News Editor Michael Greshko discusses his story on the researchers attempting to make biomanufacturing in space a reality, with News intern Julia Vaz. Next on the show, producer Kevin McLean chats with Mads Peter Heide-Jørgensen, a professor in the department of birds and mammals at the Greenland Institute of Natural Resources, about how narwhals have helped collect hard-to-reach oceanographic samples. Data collected by these long-toothed cetaceans revealed far more warm Atlantic water is pressing into the fjords of East Greenland than previously thought. Finally, the latest in our book series on biographies. This month, books host Angela Saini talks with writer Priyambada Jayakumar about her biography of M. S. Swaminathan.

  • Why tracing cyclosporiasis is so tough, and a digestible probe for the microbiome

    Why tracing cyclosporiasis is so tough, and a digestible probe for the microbiome
    Aug 20 2026
    First up on the podcast, the News team’s Diverse Voices in Science Journalism interns Mona Patterson and Laura Martín Agudelo join host Sarah Crespi to talk over some of their reporting from the summer. They chat about several stories, including why it’s so difficult to track the food-borne illness cyclosporiasis and a new map for a major highway of the human nervous system. Check out all of Patterson’s and Martín Agudelo’s stories. Next on the show, Leslie Chan, assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at the Georgia Institute of Technology and the Emory School of Medicine, describes an ingestible metabolic probe for the gut microbiome. Her team tested the pill in mice and showed they could detect an enzyme made by the microbiome that causes toxicity during some chemotherapy treatments. The signal is read from volatiles in the breath, making the test a noninvasive way to check on the activity of gut microbes. This week’s episode was produced with help from Podigy.
