Abstract: The low-down on bacteria The recent discovery of bacteria in deep sediments and rocks, seemingly able to survive for millions of years with hardly any energy supply, has profound implications. For example, it impinges on theories of the origin of life, the prospects for subsurface life on other planets, and fossil fuel formation. Not surprisingly then, there is considerable controversy regarding these claims. Now a new survey shows that bacteria in deep marine sediments are not only active but are stimulated in the subsurface by chemical and geological changes occurring on geological timescales.
