Life in the vasty deep

Where do you think most organisms on Earth live? On land? In the oceans? Nope. By some estimates, as much as one-third of all the mass of creatures on Earth could be living … beneath the seafloor.

These are tough little buggers, eking out a living in the mud and even solid rock beneath the oceans. And the only way to find them is to go drill into the seafloor. My Science News feature explores the booming world of subsurface microbiology. Because, of course, microbes are awesome.
