Every autumn, Arctic ground squirrels do something no other mammal on Earth can survive: they let their bodies freeze. This episode unpacks the extraordinary physiology behind supercooling, from the molecular scaffolding that keeps ice crystals from forming in living tissue to the brain changes that make weeks of near-death possible. If you have ever wondered where biology ends and the genuinely miraculous begins, this is the episode.
