Lake Vida, in one of Antarctica’s dry valleys, was once thought to be frozen solid. In 1995, researchers discovered the lake wasn’t completely ice -- inside an almost 20-meter-thick ice layer lay veins of super-salty water, sealed off from the rest of the world. Writing in the Proceedings of the National Academy of Sciences, Alison Murray and colleagues describe a community of bacteria that survive in the dark, salty, sub-freezing waters of the lake.
