Deep Hydrogen
Molecular hydrogen provides energy for many bacteria, in hot springs at Yellowstone and in rocks several kilometers beneath the surface. How did molecular hydrogen get inside these deep rocks, and what does this tell us about the origin of life on Earth?

Earth’s Hidden Biospheres
Two recent discoveries in astrobiology challenge many of our assumptions about an integrated biological community on Earth. At the microbial level, it seems that there may be previously hidden biospheres that exist on Earth alongside our more familiar neighbors. One such community has been found deeply buried underground, while the other lives in the sea alongside more familiar life forms.

Microbial Ecology of Hot Spring Communities in Yellowstone
New studies from NAI’s University of Colorado team published in the February 15, 2005 issue of PNAS implicate the oxidation of molecular hydrogren as the source of energy for primary productivity in high temperature microbial ecosystems in Yellowstone.
