Nevermind, I just scoured a dozen sites about the bacteria study. It seems as NASA hyped it in an attempt to make itself relevant again. The bacteria was filtering Arsenic, but still utilizing Phosphorous for it's chemical reactions. The bacterium that replaced P w/ As ended up dying like any other biologically "alive" life form.Do you have a copy of this article?
Essentially, NASA was trying to justify more exploratory vehicles to other regions of space.
The final, definitive experiments have been published, showing that GFAJ-1 is an arsenate-resistant, phosphate-dependent organism, and that it does not incorporate arsenic into its DNA
