Researchers from NAI's Marine Biological Laboratory Team continue their study of the deep biosphere, reporting the latest results in Nature.

The microbes appear to ?feed? on the oceanic crust through seawater-rock alteration reactions involving the oxidation and hydration of glassy basalt. [Source: NAI Newsletter]
