Submission + - Life found in deepest layer of Earth's crust (newscientist.com)
michaelmarshall writes: For the first time life has been found in the gabbroic layer of the crust. The new biosphere is all bacteria, as you might expect, but they are different to the bacteria in the layers above: they mostly feed on hydrocarbons that are produced by abiotic reactions deep in the crust. It could mean that similar microbes are living even deeper, perhaps even in the mantle.
