NASA held a press conference Thursday afternoon, in which she describes the discovery of life forms on arsenic-based Earth. As explained by Marc Kaufman:
All life on earth - from microbes to elephants, and us - a simple genetic model that assumes that the element phosphorus as one of six major components.
But now researchers have a bacterium that has five essential elements, but in fact, discovered phosphorus replaced by family resemblance, but toxic arsenic.
News of the discovery has led scientists to an excitation, including calls for NASA from the White House and Congress to consider whether a second line of this life is.
While speculation of possible extraterrestrial life had built the discovery, Melissa Bell takes us back to earth:
Before you disappointed to realize that it's not as sexy as a little green man is a big deal. No other living beings exist in arsenic. Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur - - life could not exist, he had long believed that without six key elements. This discovery shows "life-as-we-know-it could be much more flexible than we think, in general, or can imagine," Felix Wolf, a NASA biochemist Simon said the post-Marc Kaufman .
Satire Post columnist Peter Alexander had this to say about the new discovery:
I think about this bacteria as a kind of hippie. "Oh, you're still with phosphorus? He asked." Yes, I loved the phosphorus during his blue period, but I moved to arsenic. "" Is not it inevitable? " common soil bacteria nervously asked. "It is an acquired taste," the bacteria respond arsenic.
Apparently, the place to find this type of bacteria, is Mono Lake, California. Although the announcement that someone has found a completely alien form of life in California is not exactly breaking news. Usually, the answer to California in search of life completely alien to him is a reality TV show.
However, this is great news.
