The discovery of solitary little critters deep beneath Earth's surface has set the world of microbiology on its head while exciting astrobiologists about the possibility of life on other planets. A community of bacteria was found 2.8 kilometers below ground in a goldmine and it lives completely alone and completely independent of any other [...]

Fraser. I think the quote from Ms Atkinson re: Prof. Chinian.."the energy from uranium in the surrounding rocks", or some such...is incorrect. The bacteria get their energy from sulfate reduced to sulfides, as in :http://en.wikipedia.org/wiki/Sulfate-reducing_bacteria


pete. As far as I know, no bacteria metabolizes uranium or alphas or betas or gammas...not even the Hulk. They should be similar in chemical function to the hot smoker bacteria under the oceans around thermal vents, and the thermophiles of Yellowstone and Iceland.
