Earth’s deepest life scavenges carbon

In one of the deepest layers of Earth’s crust ever explored, researchers are finding life. An analysis of rock samples from the bottom of the Indian Ocean has revealed microbes adapted to life within nutrient-poor hairline fractures in the Earth. Researchers found several species of bacteria, fungi and archaea that live in the rocks and feed on carbon from fragments of amino acids and other organic molecules carried in deep ocean currents.
