Strange Bacteria Sustains Itself Without Sunlight

Hahnsoo writes "A colony of bacteria found 2.8 kilometers below the Earth's surface in a South African gold mine is able to sustain itself without energy from the Sun. While sub-surface colonies of microorganisms utilizing sulfur (mostly near deep sea hydrothermal vents) is not new, this particular colony is unusual. The colony does it by relying on radioactive uranium to split water into hydrogen gas. Thus, instead of solar energy and photosynthesis, this species relies on radioactive materials and sulfur/hydrogen to facilitate its energy needs. There is some speculation about life on other planets in the article as well."

    What is this sunlight you speak of?

    We manage to sustain ourselves using colonies of microorganisms utilising twinkie bars and coke (mostly near mom's fridge).
    We rely on radiation from our CRT monitors and heat from mom's washing machine to act as a catalyst converting the food bars into into methane gas. Thus instead of having a nice basement, its a desolate wasteland where noone would dare to tread.

    There is some speculation about how life evolved inside such places (or should that be devolved).

      There is also some speculation about how these organisms manage to reproduce when they do not engage in any type of mating or sexual reproduction.

      I beleive sexual reproduction is acheived through bumping into each other at star trek conventions.

      That's easy. They actually reproduce by "seeding" themselves through intar-web tubes, into what is known as a "bit-torrent."

      Sadly, more true than many would realize...

      I think you mean by dragging outsiders to conventions, whereupon their bodies are possessed by the hive mind, thus increasing our numbers ;)

    Why is this news? Clearly you've never been to a Linux User's Group meeting.

    So now we have completely different lifeforms available does that mean we have to go and kill them?

    If Steve Irwin were still alive, he would capture it, thoroughly describe it to the viewers at home, shove his thumb up it's butt, and then say "Crikey, its a naughty boy!"
