  • 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.

  • Rising infections from a dusty devil, and nailing down when our ancestors became meat eaters

    Rising infections from a dusty devil, and nailing down when our ancestors became meat eaters
    Jan 16 2025
    First up this week, growing numbers of Valley fever cases, also known as coccidioidomycosis, has researchers looking into the disease-causing fungus. They’re exploring its links to everything from drought and wildfires to climate change and rodent populations. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss her visit to a Valley fever research site in the desert near Bakersfield, California, where researchers are sampling air and soil for the elusive fungus. Next up, scientists are trying to pin down when meat eating became a habit for human ancestors. It’s long been hypothesized that eating meat drove big changes in our family tree—such as bigger brains and more upright posture. Tina Lüdecke, a group leader at the Max Planck Institute for Chemistry and honorary research fellow at the Evolutionary Studies Institute at the University of the Witwatersrand, investigated the diet of our ancient hominin relatives Australopithecus. Her team used nitrogen isotope ratios from the tooth enamel in seven Australopithecus individuals in South Africa to determine what predominated in their diets at the time—meat or veg.
