First up this week, Newsletter Editor Christie Wilcox joins host Sarah Crespi to discuss stories from the sea, including why scientists mounted cameras on seabirds, backward and upside-down; newly discovered organisms from the world’s deepest spot, the Mariana Trench; and how extremely venomous, blue-lined octopus males use their toxin on females in order to mate.

Next on the show, J. Chris McKnight, a senior research fellow in the Sea Mammal Research Unit at the University of St. Andrews, talks about testing free-living seals to see how they respond to different carbon dioxide or oxygen levels in the air. It turns out they don’t respond like other mammals, which go into panic under high carbon dioxide; instead, seals appear to directly detect oxygen, a safer bet when your life is mostly spent diving deep underwater.

Folge vom 13.03.2025Why sign language could be crucial for kids with cochlear implants, studying the illusion of pain, and recent political developments at NIHFirst up this week, science policy editor Jocelyn Kaiser joins host Sarah Crespi to discuss the latest news about the National Institutes of Health—from reconfiguring review panels to canceled grants to confirmation hearings for a new head, Jay Bhattacharya. Next, although cochlear implants can give deaf children access to sound, it doesn’t always mean they have unrestricted access to language. Producer Meagan Cantwell talks with Contributing Correspondent Cathleen O’Grady about why some think using sign language with kids with cochlear implants gives them the best chance at communicating fully and fluently. Finally, using a pain illusion to better understand how the brain modulates pain. Francesca Fardo, an associate professor in the department of clinical medicine at Aarhus University, talks with host Sarah Crespi about the role of learning and uncertainty in pain perception. It turns out, the more uncertain we are about a sensation that could be painful, the more pain we feel. This week’s episode was produced with help from Podigy.

Folge vom 06.03.2025Intrusive thoughts during pregnancy, paternity detectives, and updates from the Trump TrackerFirst up this week, International News Editor David Malakoff joins host Sarah Crespi to discuss the most recent developments in U.S. science under Donald Trump’s second term, from the impact of tariffs on science to the rehiring of probationary employees at the National Science Foundation. Next, we tackle the question of extra-pair paternity in people—when marriage or birth records of parentage differ from biological parentage. Contributing Correspondent Andrew Curry writes about researchers looking into the question of how often children are genetically unrelated to their presumed fathers by using genealogy and genetic testing. Finally, Susanne Schweizer, Scientia associate professor at the University of New South Wales, talks about her article on intrusive thoughts in the perinatal period as part of a special issue on women’s health in Science Advances. Almost all pregnant and recent mothers experience intrusive thoughts about harm coming to their offspring. Schweizer and colleagues suggest gaining a better understanding of intrusive thoughts during this highly predictable window could help explain the phenomenon more broadly.

Folge vom 27.02.2025Keeping transgenic corn sustainable, and sending shrunken heads homeFirst up this week, Kata Karáth, a freelance journalist based in Ecuador, talks with host Sarah Crespi about an effort to identify traditionally prepared shrunken heads in museums and collections around the world and potentially repatriate them. Next, genetically modified Bt corn has helped farmers avoid serious crop damage from insects, but planting it everywhere all the time can drive insects to adapt to the bacterial toxin made by the plant. Christian Krupke, an entomology professor at Purdue University, talks about the economics of planting Bt corn and how farmers could save money and extend the usefulness of this transgenic plant by being selective about where and when they plant it.
