NASA just announced the discovery of a New Life Form on Earth.

The new "player" in the game of LIFE is called GFAJ-1. It' s a bacteria whose DNA is different to what we know today. Instead of using phosphorus, the newly discovered microorganism, and found in Mono Lake, Californiaâ€"uses the poisonous arsenic for its building blocks.

NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.

Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.

"The definition of life has just expanded," said Ed Weiler... "As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it."

This finding of an alternative biochemistry makeup will alter biology textbooks and expand the scope of the search for life beyond Earth. The research is published in this week's edition of Science Express.

NASA has discovered a new life formâ€"called GFAJ-1â€"that doesn't share the biological building blocks of anything currently living in planet Earth. It's capable of using arsenic to build its DNA, RNA, proteins, and cell membranes. This changes everything.
