When I first heard of NASA's impending announcement yesterday, I got giddy with thoughts of Aliens, District 9, and, of course, Predator. But the big discovery they officially came forward with today has a lot less to do with E.T., and more to do with bacteria and evolution. Not as cool (ha), but still pretty amazing.

Basically, a NASA-funded research team found a foreign bacteria that lives off of arsenic - you know, the poisonous chemical element that SHOULD kill any and all living things. These little freaky bugs replicate themselves by replacing phosphorous with arsenic in their cells and DNA. The microorganism was found in Mono Lake, California.

Folks, we've officially entered the Twilight Zone.
