Science Magazine Podcast

First up on the podcast, Senior International Correspondent Richard Stone joins host Sarah Crespi to discuss the surprising commonalities between our immune systems and the tools bacteria use to defend themselves against viruses. These unexpected parallels have become rich ground for researchers investigating new molecular biology tools and model systems for immune research.

Next on the show, Dominic Rohner, a professor of economics at the Geneva Graduate Institute and University of Lausanne, talks about the impact of cuts in international aid on violent conflict in Africa. His team harnessed the natural experiment of the U.S. Agency for International Development (USAID) work stoppage ordered by the Trump administration in early 2025 to find links between the sudden withdrawal of high levels of aid to increases in conflict.

Finally, Valerie Thompson, Science’s books and media editor, interviews undergraduate student and author Theo Baker. Baker wrote the book How to Rule the World: An Education in Power at Stanford University, which covers the heavy involvement of Silicon Valley investors in Stanford University and his investigation of research misconduct by former Stanford President Marc Tessier-Lavigne.

First up on the podcast, Meagan Cantwell produced a segment with Contributing Correspondent Kai Kupferschmidt on the fight against deepfakes. Kupferschmidt talks with Hany Farid, professor at the University of California, Berkeley, about the never-ending battle against fake imagery and why Farid is not giving up.

Next on the show, building a tough, bio-compatible capsule for engineered bacteria. Tetsuhiro Harimoto talks about the challenges of keeping living bacteria inside a hydrogel capsule and the advantages of using engineered bacteria as sensors and medicine dispensers inside the body. (Harimoto completed this work as a postdoc at Harvard University and will start as a professor at Cornell University in the fall.)

First up on the podcast, along Brazil’s Juruá River, local residents have been working with scientists to manage a giant fish called the arapaima—affecting the land, the people, and the economy. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about this collaborative effort.

Next on the show, how moonlight affects nocturnal animals. Carlos Camacho, a researcher at the Doñana Biological Station, talks about the Moon-inflected habits of a nighttime foraging bird, the red-necked nightjar. His team found that the extra light provided by the full Moon allows these birds to consume more insects at night. And the timing of their long-haul migration between Europe and Africa is linked to the cycles of the Moon.

Last up this week, Science Editor-in-Chief Holden Thorp talks with Timothy Snyder, historian and author of the book On Tyranny: Twenty Lessons from the Twentieth Century. They discuss the role of institutions, professional ethics, and personal beliefs for scientists in tough political times.

First up on the podcast, Online News Editor David Grimm shares a batch of fun stories with podcast host Sarah Crespi—from spider hearts racing when traffic gets loud to a disease-preventing house. Staff Writer Adrian Cho hops in to help discuss the possibility of black holes without singularities at their center.

Next on the show, epigenetics has become a hot topic in pop science but the ethical conversation is not keeping up. The idea that parents can pass down epigenetic marks from environmental toxins or trauma to their children—without changes in DNA—has been around for decades but the research in people is lacking. Jackie Leach Scully, a professor of bioethics and director of the Disability Innovation Institute at the University of New South Wales, discusses where the research actually is and the concerns that may arise if such marks do appear to impact the young.

Last up this week, we are launching our 2026 biography books series with books host Angela Saini and Science books editor Valerie Thompson. The pair discusses the difficulty of picking biographies and what can be learned about science, fame, and researchers as people from reading these types of books.

First up on the podcast, freelance science and environmental journalist Quentin Septer joins host Sarah Crespi to talk about a controversial uranium mine getting fast-tracked in South Dakota. Septer chatted with locals, scientists, and regulators to learn more about the geology of the region and the promise of cleanup after the miners go home.

Next on the show, looking at cells that don’t get cancer. Giulio Ciucci, a postdoctoral researcher at the International Centre for Genetic Engineering and Biotechnology, talks about the infrequency of heart cancer and how the mechanical load that heart cells endure makes them resist turning cancerous.

*CORRECTION: In the on this site summary in this episode, the book author in the review by Kai Kupferschmidt was listed incorrectly. The correct information is: True Color by Kory Stamper, Knopf, 2026.
