Nasa found microbes that can live off arsenic

Unfortunately not from outer space, though. Still, very cool.

As NASA announced today, they found bacteria in Mono Lake, a lake with water that's essentially just one poisonous soup, that have managed to incorporate arsenic instead of phosphate into their bio systems (even 

replacing it in their DNA). Thus, they strive in this otherwise very deadly environment.

This is a really newsworthy discovery, for it supports the notion that life is not absolutely dependant on those substances that most ordinary life-forms (including humans) use to sustain themselves, but may arise, or adapt to all sorts of environments. It really widens the scope of possible worlds to search for life!

It also goes straight in the face of creotards, demonstrating once again that evolution works like a breeze.
