  • Why chatbots lie, and can synthetic organs and AI replace animal testing?

    Why chatbots lie, and can synthetic organs and AI replace animal testing?
    Aug 14 2025
    First up on the podcast, producer Meagan Cantwell and Contributing Correspondent Sara Reardon discuss alternative approaches to animal testing, from a heart on a chip to a miniorgan in a dish. Next on the show, Expert Voices columnist Melanie Mitchell and host Sarah Crespi dig into AI lies. Why do chatbots fabricate answers and pretend to do math? Mitchell describes the stress tests large language models undergo—called red teaming—and the steps needed to better understand how they “think.” Melanie Mitchell is a professor at the Santa Fe Institute.

  • Why anteaters keep evolving, and how giant whales get enough food to live

    Why anteaters keep evolving, and how giant whales get enough food to live
    Aug 7 2025
    First up on the podcast, Online News Editor David Grimm brings stories on peacock feathers’ ability to emit laser light, how anteaters have evolved at least 12 times, and why we should be thanking ketchup for our French fries. Next on the show, rorqual whales, such as the massive blue whale, use a lunging strategy to fill their monster maws with seawater and prey, then filter out the tasty parts with baleen sieves. Lunging for food when you weigh 100 tons seems like it would be an energetically expensive way to meet your dietary needs. But as Ashley Blawas, a postdoctoral researcher at the Hopkins Marine Station at Stanford University, describes in Science Advances this week, lunge-feeding whales have a few tricks up their sieves and use much less energy than predicted.

  • Wartime science in Ukraine, what Neanderthals really ate, and visiting the city of the dead

    Wartime science in Ukraine, what Neanderthals really ate, and visiting the city of the dead
    Jul 31 2025
    First up on the podcast, Contributing Correspondent Richard Stone joins host Sarah Crespi to talk about the toll of the ongoing conflict in Ukraine and how researchers have been mobilized to help the war effort. In June, Stone visited the basement labs where Ukrainian students modify off-the-shelf drones for war fighting and the facilities where biomedical researchers develop implants and bandages for wounded soldiers. Next on the show, the isotopic ratios in our teeth and bones record the chemistry of what we eat. When anthropologists recently applied this technique to Neanderthals, they were surprised to find that when it comes to eating meat, our hominin cousins appeared to be on par with lions. Melanie Beasley, assistant professor of anthropology at Purdue University, has an explanation for why Neanderthals chemically look like hypercarnivores: They were just eating a lot of maggots. She talks about how she tested this idea by studying maggots that were fed putrefying human flesh. Last up on this episode, a new installment of our series of books on death and science. This month’s books host Angela Saini talks with Ravi Nandan Singh, a sociologist at Shiv Nadar University, about his book Dead in Banaras: An Ethnography of Funeral Travelling.
