Oil-dwelling bacteria are social creatures in Earth's deep biosphere
Dartmouth NH (SPX) Dec 16, 2014
Oil reservoirs are scattered deep inside the Earth like far-flung islands in the ocean, so their inhabitants might be expected to be very different, but a new study led by Dartmouth College and University of Oslo researchers shows these underground microbes are social creatures that have exchanged genes for eons. The study, which was led by researchers at Dartmouth College and the University of Oslo, appears in the ISME Journal. A PDF is available on request. The findings shed new light on t ... read more

Microbes in deep-sea rocks eat methane, lots of it
Most methane is buried deep in the ground. Some of it, however, bubbles up to escape, and that's good news for methane-loving microbes living in rocks that gather along the ocean's floor near methane sea vents, munching away on the colorless, odorless assembly of hydrocarbons. ... more
