Watching a spiders’ heart beat, epigenetic ethics, and what science biographies reveal about fame

Watching a spiders’ heart beat, epigenetic ethics, and what science biographies reveal about fame

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.
