NASA paper on arsenic-bred organisms finds phosphorous-based detractors
Calm down, everyone, please take your seats. Now, no one here is saying arsenic-bred life is impossible -- they're not saying that, so your science fiction novel (which should be beyond the outline phase and in rough draft form) is conceptually fine. But, as you might have heard, there are a number of scientists -- including some that co-authored a 2007 paper that called for such arsenic-based research -- who are calling into question the paper behind NASA's big astrobiological announcement, noting what they see as "fatal flaws" and errors in methodology. Frankly, this kind of thing happens with most-to-all science papers, but given all the self-made hooplah surrounding the unveil, a public opposition seems poetically appropriate. Expect this toxic fight to propagate throughout an assortment of scientific journals, the initial test trialed numerous times over in hopes of recreating (and further verifying). Make no mistake, someone'll be bringing a beaker to the test tube fight.
NASA reveals arsenic-bred organisms, search for life gets broader parameters
If you were hoping NASA was going to announce the very first tweet from an extraterrestrial being, sorry to break your heart -- it is astrobiological, but the findings are actually borne of this rock. Researchers in Mono Lake, California, have discovered a microorganism (pictured) that uses arsenic instead of phosphorous to thrive and reproduce. The latter, as far as terrestrial life is concerned, is a building block of life along with carbon, hydrogen, nitrogen, oxygen, and sulfur, all integral to our DNA and RNA. Arsenic, meanwhile, is generally considered poisonous -- but "chemically it behaves similarly to phosphate," apparently making for a good substitution. In other words, NASA's proven that life can be made with components different than our current assumptions, both locally and beyond the stars. Seems entirely logical, if you ask us. (A silicon-based Horta, Mr. Spock?) So, what about other atypical life-forming chemicals? NASA isn't speculating. That sound you hear is a thousand light bulbs popping up as science fiction writers everywhere conjure up brand new super villains -- and a thousand Chemistry professors writing new extra credit questions for their fall semester finals.
