Going Wild with Dr. Rae Wynn Grant is a different kind of nature show about the human drama of saving animals. From a paleoanthropologist who hunts fossils in conflict zones to someone who helped save an endangered species while in prison, in season four we will hear from real-life heroes and nature advocates with widely different expertise and life experiences that led them to be champions for the natural world. Wildlife biologist and host Dr. Rae Wynn-Grant has been studying wild animals i ...

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

DNA science. Artificial intelligence. Smartphones and 3D printers. Science and technology have transformed the world we live in. But how did we get here? It wasn’t by accident. Well, sometimes it was. It was also the result of hard work, teamwork, and competition. And incredibly surprising moments. Hosted by bestselling author Steven Johnson (“How We Got To Now”), American Innovations uses immersive scenes to tell the stories of the scientists, engineers, and ordinary people behind the great ...

Great White Shark Populations Have Interesting DNA

Great white shark DNA is one of the most puzzling mysteries in marine biology. Recent research has revealed that despite being one species, great whites have split into three distinct genetic groups across the globe. What’s even stranger: their nuclear DNA and mitochondrial DNA tell conflicting stories, leaving scientists scratching their heads.
Shark philopatry—the tendency of females to return to their birthplace to give birth—adds another layer to this mystery. While philopatry has been well documented in species like lemon sharks and blacktip sharks, great whites show patterns that don’t neatly fit the rules. This episode unpacks how philopatry and DNA research intersect, why sharks defy easy explanations, and how these puzzles matter for conservation.
Shark conservation depends on solving these mysteries. If different populations are genetically distinct, protecting one region isn’t enough. By understanding how sharks move, breed, and adapt, we can build stronger policies, create better marine protected areas, and ensure these apex predators survive in a rapidly changing ocean.
