I’m not going to try to write much about how amazing this is right now, since I’m not sure I could do it justice–but here is a link to the relevant Gizmodo post and the Slashdot comment thread (those are usually enlightening). From Gizmodo:
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.
But not this one. This one is completely different. Discovered in the poisonous Mono Lake, California, this bacteria is made of arsenic, something that was thought to be completely impossible. While she and other scientists theorized that this could be possible, this is the first discovery. The implications of this discovery are enormous to our understanding of life itself and the possibility of finding beings in other planets that don’t have to be like planet Earth.
The official announcement hasn’t happened yet–it’s scheduled for 2 pm. Expect an update from us, too.
