    The quest for Leonardo da Vinci’s DNA
    Jan 23 2026
    In this episode of Science Quickly, host Kendra Pierre-Louis speaks with forensic scientist Rhonda Roby about an ambitious effort to uncover traces of Leonardo da Vinci’s DNA using modern forensic techniques. Roby and her colleagues are carefully sampling centuries‑old artworks, working with extremely small amounts of biological material, to learn more about Leonardo himself and the history of his art while also advancing methods that could one day help authenticate artworks. The episode explores how forensic approaches typically used in criminal investigations are being applied to a 500‑year‑old historical puzzle.

    Jan 19 2026
    In this episode of Science Quickly, we unpack the Environmental Protection Agency’s controversial decision to change how it calculates health benefits from regulating certain air pollutants, a move that experts warn could lead to dirtier air and worse health outcomes. And we’ve achieved a major milestone in cancer care, with five-year survival rates hitting a record high, but looming policy threats could stall progress. Plus, NASA’s first-ever medical evacuation from the International Space Station could offer lessons for future missions.
