The era of AI-generated viruses is here. Some scientists are using AI to design viruses that can attack bacteria. The hope is that these tailor-made viruses can fight drug-resistant bacterial infections in people. And longer-term, Brian Hie, the Stanford researcher spearheading this project, hopes that AI can help create more complicated biological systems to treat formidable diseases. But some experts warn that placed in the wrong hands, this technology could create the next pandemic.

Ever wish you could have been part of the Lewis and Clark expedition? Us too. The Corps of Discovery came across scores of plants and animals that were new to Western science: Grizzly bears, ponderosa pines, a “barking squirrel” that William Clark would later call the prairie dog. A modern effort is underway to see how much the country’s wildlife has changed in the 220-some years since their journey. Host Nate Rott tags along with some scientists re-surveying a part of the expedition’s route in western Montana. And he wishes he was in better shape.

If you’re a guy – or even just friends with a guy – and on the Internet, you may have noticed that testosterone discourse is everywhere. There’s Defense Secretary Pete Hegseth announcing testosterone screenings for soldiers, Joe Rogan discussing hormone therapy, and influencers discussing high- and low-T levels. Those levels affect more than just sex. They also affect metabolism, bone health, muscle mass, red blood cell production and brain function. NPR science reporter Will Stone took a deep dive into it all: What deficiency looks like in men, what doctors recommend and what the research says about who actually needs testosterone replacement therapy.

Getting caught inside a tornado.  But when you’re an atmospheric scientist who studies supercell thunderstorms—with a special interest in the ones that cause tornadoes—that sort of thing is a bit of an occupational hazard. Lucky for Perry, he also made a split-second decision while in the tornado that may be the smartest thing he’s ever done. So today on the show: What we can learn from nature at its wildest.
