Yeah, not quite intelligent life on other planets, I’m afraid. According to a British paper, the discovery is about:

a bacterium living in an arsenic lake near California’s Yosemite National Park.
The finding is important because the bacterium uses arsenic in place of phosphorus – an element previously considered vital for all forms of life.
If there can be life without phosphorus then there are thousands more planets which could sustain life of some sort.

The official press conference is later today. I, for one, welcome our new arsenic bacterium overlords.
