Episode Details

Stanford researchers have mapped a previously unknown brain circuit responsible for chronic pain that operates entirely separately from normal pain pathways — a potential turning point for the 60 million Americans who suffer from it. Johns Hopkins scientists unveiled a nasal-delivery DNA vaccine targeting tuberculosis in people who already have the disease, designed to help the immune system clear bacteria that antibiotics can't fully eliminate. A new study complicates the Ozempic hype, finding that behavioral factors play a surprisingly significant role in why the blockbuster drug works dramatically for some people and barely at all for others. Cornell researchers may have cleared a major hurdle in the decades-long search for male birth control, using a compound that temporarily and reversibly shuts down sperm production in mice — without hormones. Meanwhile, a UC Irvine climate study found that nitrous oxide is breaking down in the atmosphere faster than models predicted, and a cosmological paper proposes that gravitational waves from the Big Bang may have actually generated dark matter — connecting two of physics' deepest mysteries.
