Arsenic-based life form discovered on Earth

Not the type of Alien Lifeforms we want to see but definitely Alien.

NASA held a press conference Thursday afternoon in which they revealed the discovery of arsenic-based life forms on Earth. As Marc Kaufman explained:

All life on Earth - from microbes to elephants and us - is based on a single genetic model that requires the element phosphorus as one of its six essential components.

But now researchers have uncovered a bacterium that has five of those essential elements but has, in effect, replaced phosphorus with its look-alike but toxic cousin arsenic.

News of the discovery caused a scientific commotion, including calls to NASA from the White House and Congress asking whether a second line of earthly life has been found.
