Scientists Found a Deep-Sea ‘Death Pool’ That Vanished. It May Show How Earth’s First Life Survived

Scientists Found a Deep-Sea ‘Death Pool’ That Vanished. It May Show How Earth's First Life Survived

Marine ecologists used to call them “black puddles of death.” Just a decade ago, blue-green deep-sea brine pools were assumed to be oxygen-depleting dead zones, despite the wealth of deeply strange and extraterrestrial “extremophiles” that biologists have found living at their margins. But something was alive inside these phenomenally salty underwater lakes, and now researchers … Read more
