Living microbes discovered in Earth's driest desert with new separation technique

The Atacama Desert, which runs along the Pacific Coast in Chile, is the driest place on the planet and, largely because of that aridity, hostile to most living things. Not everything, though—studies of the sandy soil have turned up diverse microbial communities. Studying the function of microorganisms in such habitats is challenging, however, because it's difficult to separate genetic material from the living part of the community from genetic material of the dead.
