  • How the mantis shrimp builds its powerful club, and mysteries of middle Earth

    How the mantis shrimp builds its powerful club, and mysteries of middle Earth
    Feb 6 2025
    First up this week, Staff Writer Paul Voosen joins host Sarah Crespi to discuss mapping clogs and flows in Earth’s middle layer—the mantle. They also talk about recent policy stories on NASA’s reactions to President Donald Trump’s administration’s executive orders. Next, the mantis shrimp is famous for its powerful club, a biological hammer it uses to crack open hard shells. The club applies immense force on impact, but how does it keep itself together blow after blow? Nicolas Alderete is an associate researcher at the National Institute of Standards and Technology, but at the time of the work he was a graduate researcher in theoretical and applied mechanics at Northwestern University. He joins the podcast to discuss the makeup of the mantis shrimp’s club and how it uses “phononics”—specialized microstructures that can reduce or change high-frequency vibrations—to reduce wear and tear when smashing and bashing.

  • Why it pays to scratch that itch, and science at the start of the second Trump administration

    Why it pays to scratch that itch, and science at the start of the second Trump administration
    Jan 30 2025
    First up this week, we catch up with the editor of ScienceInsider, Jocelyn Kaiser. She talks about changes at the major science agencies that came about with the transition to President Donald Trump’s second administration, such as hiring freezes at the National Institutes of Health and the United States’s departure from the World Health Organization. Next, producer Kevin McLean talks with Dan Kaplan, a professor in the departments of immunology and dermatology at the University of Pittsburgh, about why it sometimes pays to scratch that itch. It turns out scratching may be our bodies’ end run around pests and pathogens attempting to steal blood or invade the body. This week’s episode was produced with help from Podigy.

  • Unlocking green hydrogen, and oxygen deprivation as medicine

    Unlocking green hydrogen, and oxygen deprivation as medicine
    Jan 23 2025
    First up this week, although long touted as a green fuel, the traditional approach to hydrogen production is not very sustainable. Staff writer Robert F. Service joins producer Meagan Cantwell to discuss how researchers are aiming to improve electrolyzers—devices that split water into hydrogen and oxygen—with more efficient and durable designs. Next, Robert Rogers, who was a postdoctoral fellow in molecular biology at Massachusetts General Hospital when this work was conducted, talks with host Sarah Crespi about the idea of chronic hypoxia as medicine. Efficacious in mouse disease models, the big question now is whether long-lasting reduced oxygen could help people with certain serious conditions, such as mitochondrial defects or brain inflammation. The pair discuss what we know so far about this potential treatment and the challenges of delivering low levels of oxygen around the clock. This week’s episode was produced with help from Podigy.
