NASA Finds New Life
NASA has discovered a completely new life form that doesn't share the biological building blocks of anything currently living in planet Earth, using arsenic to build its DNA, RNA, proteins, and cell membranes. This changes everything.
All life on Earth is made of six components: Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Every being, from the smallest amoeba to the largest whale, share the same life stream. Our DNA blocks are all the same. NASA scientist Felisa Wolfe Simon and her team have found a bacteria whose DNA is completely alien to what we know today. Instead of using phosphorus, the newly discovered microorganism—called GFAJ-1—uses the poisonous arsenic for all its building blocks.
