Not sure how real this is, but most likely this is correct.

A new form of bacteria found HERE ON EARTH has a complete and different building block than any other living thing we know of. The discovery suggest that life on other planets close to ours is possible. We’ve just been looking for only one sign of life.

I think GT reader, JP figured it out earlier:

Ok, they´ve found some bacteria in a Californian lake, that eats arsenic.

As I suspected, no alien life forms to be announced by NASA…

Oh well…I guess that is some exciting news…*puts away ‘Welcome to Earth’ sign*

It’s not aliens. NASA’s announcement that hasn’t officially been made has been leaked as quickly as a Black Friday sale. The announcement, which NASA said had to do with new life, and many, including us, hoped meant somewhere out in the universe and had the words “little” “green” and “men” in it. But alas, no.

But before you are too disappointed, read on.

NASA’s big announcement involves arsenic, here on Earth. NASA has discovered a completely new life form that doesn’t share the biological building blocks of ANYTHING else on planet Earth.

Wow.

So, aliens theoretically still are involved.

The bacteria has completely alien DNA from anything that we know of as existing today.

All life on Earth, from fungi to humans, is made up of these six things: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur.

This new life form uses arsenic instead of phosphorus.

So, you may still want to tune in to NASA’s press conference at 2 p.m. Eastern Time today for the details. We’ll be there!
