Arsenic based lifeform? Well, sort of - NASA knows how to do media

Recently there was some hype that NASA had possibly found evidence of alien life!

News agencies reacted variously (see Fox News: Are Aliens Among Us? Sort of, NASA Says

But if you really want to understand it, check out the post from one of the Science blogs I occasionally read. See:"It's not an arsenic-based life form" by PZ Meyers.

Great article about an extremophile bacteria found right here on earth, that is really arsenic tolerant. So arsenic tolerant that it is able to substitute it for one of our related basic building blocks of life, phosphorus - even in the bacteria's DNA. Check out what Mr. Meyers has to say.
