  Psychoactive substances helped spur Andean civilization, and breaking barriers to education 10.09.2026 33min

  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 03.09.2026 27min

  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.

  How childhood environments shape the brain, and how susceptible is the Atlantic Ocean’s current to climate change? 11.06.2026 31min

  First up on the podcast, producer Kevin McLean talks with Staff Writer Paul Voosen about the latest on the Atlantic Meridional Overturning Circulation, or AMOC. Researchers have long been concerned that global warming could cause a collapse in the AMOC, which would trigger dramatic cooling in Northern Europe. But recent data and models suggest the AMOC may be more resilient than previously thought. Next on the show, Scott Marek, assistant professor in the Mallinckrodt Institute of Radiology at Washington University School of Medicine, talks with host Sarah Crespi about brainwide association studies (BWAS) for childhood brain development. BWAS measure structure and function across many brains and look for correlations between these measures and behavior, disease, and environment. In this work, Marek and colleagues focus on how socioeconomic factors—captured by zip code—are strongly correlated with certain brain differences in more than 4000 children ages 9.5 to 11. The work also suggests lack of sleep and excess screen time could mediate the influence of socioeconomic conditions on differences in brain structure and function.

  Disembodied human brains, immortal bits of sea cucumber, and fame in Galileo’s time 28.05.2026 45min

  First up on the podcast, a company is using whole brains—maintained with specialized life support—to study new drugs. Freelance science journalist Sara Reardon joins host Sarah Crespi to talk about the advantages and ethical considerations of keeping brains intact but inactive. Next on the show, when some lizards lose their tails, they might regenerate new ones. But what happens to the old tail? Whereas a castoff lizard tail quickly decomposes, this isn’t the case for the castoff tube feet of the sea cucumber, Psolus fabricii. Sara Miller Jobson, a Ph.D. student at the Memorial University of Newfoundland, describes how these “living” limbs healed after amputation and then survived for more than 3 years in just seawater. Their survival in such simple conditions, while maintaining a complex tissue with a functioning immune response, could make amputated tube feet a useful model system for studying regeneration. Finally this week, the first in our book series on science biographies. Books host Angela Saini talks with historian Anna-Luna Post about her recent book, Galileo’s Fame: Science, Credibility, and Memory in the Seventeenth Century, which explores how fame shaped the scientific fortunes of Galileo Galilei.
