A surprising array of subterranean microorganisms can be found living in a variety of geological formations. In his Perspective, Ghiorse reports on a recent meeting in Davos, Switzerland, on subsurface microbiology. Among the exciting topics being discussed in this field are new hypotheses on origins and long-term survival of microbial life in deep crustal rocks, subsurface ecosystems supported by chemosynthetic primary production, and the possibility of new sources of industrially important organisms.
