How extreme bacteria squeeze water from a stone
Johns Hopkins University microbiologist Jocelyne DiRuggiero wanted to find out how it’s possible for a microbe to carry out photosynthesis in an environment where there is essentially no water available. So she collaborated with University of California, Irvine, materials scientist David Kisailus, who probed the biogeochemical relationship between microbe and rock using a battery of analytical tools usually reserved for studying nonliving materials.
