• Why sign language could be crucial for kids with cochlear implants, studying the illusion of pain, and recent political developments at NIH

  First 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.   About the Science Podcast   Authors: Sarah Crespi; Meagan Cantwell; Cathleen O’Grady; Jocelyn Kaiser Learn more about your ad choices.

• Intrusive thoughts during pregnancy, paternity detectives, and updates from the Trump Tracker

  First 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.   This week’s episode was produced with help from Podigy.   About the Science Podcast Learn more about your ad choices.

• Keeping transgenic corn sustainable, and sending shrunken heads home

  First 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.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kata Karáth Learn more about your ad choices.

• Shrinking AI for use in farms and clinics, ethical dilemmas for USAID researchers, and how to evolve evolvability

  First up this week, researchers face impossible decisions as U.S. aid freeze halts clinical trials. Deputy News Editor Martin Enserink joins host Sarah Crespi to talk about how organizers of U.S. Agency for International Development–funded studies are grappling with ethical responsibilities to trial participants and collaborators as funding, supplies, and workers dry up.   Next, freelance science journalist Sandeep Ravindran talks about creating tiny machine learning devices for bespoke use in the Global South. Farmers and medical clinics are using low-cost, low-power devices with onboard machine learning for spotting fungal infections in tree plantations or listening for the buzz of malaria-bearing mosquitoes.   Finally, Michael Barnett, a postdoctoral researcher at the Max Planck Institute for Evolutionary Biology, joins the podcast to discuss evolving evolvability. His team demonstrated a way for organisms to become more evolvable in response to repeated swings in the environment.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Sandeep Ravindran; Martin Enserink  Learn more about your ad choices.

• Training AI to read animal facial expressions, NIH funding takes a big hit, and why we shouldn’t put cameras in robot pants

  First up this week, International News Editor David Malakoff joins the podcast to discuss the big change in NIH’s funding policy for overhead or indirect costs, the outrage from the biomedical community over the cuts, and the lawsuits filed in response.   Next, what can machines understand about pets and livestock that humans can’t? Christa Lesté-Lasserre, a freelance science journalist based in Paris, joins host Sarah Crespi to discuss training artificial intelligence on animal facial expressions. Today, this approach can be used to find farm animals in distress; one day it may help veterinarians and pet owners better connect with their animal friends.   Finally, Keya Ghonasgi, a postdoctoral fellow at the Georgia Institute of Technology, talks about a recent Science Robotics paper on the case against machine vision for the control of wearable robotics. It turns out the costs of adding video cameras to exoskeletons—such as loss of privacy—may outweigh the benefits of having robotic helpers on our arms and legs.    This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Christa Lesté-Lasserre; David Malakoff Learn more about your ad choices.
