Diana Northup can get extreme about extremophiles, microbes that thrive in environments that would terminate us humans in seconds flat. "We think we're superior beings, but these guys are really where it's at," says Northup, a microbiologist and associate professor at the University of New Mexico and an associate in the university's Museum of Southwestern Biology.
As often as she can, Northup and other members of SLIME (Subsurface Life in Mineral Environments), a loose affiliation of cave scientists working on geomicrobiological interactions in caves, don their caving gear and descend into caverns like Lechuguilla and Mexico's Cueva de Villa Luz ("Cave of the Lighted House"). They go in search of bacteria that gobble up hydrogen sulfide gas and other noxious chemicals like we do bread and water. As this interview reveals, she and other SLIME members are finding that these bizarre creatures may hold clues not only to the earliest life on Earth but to the possibility of life in outer space.
