Submission + - NASA's "arsenic microbe" science under fire

radioweather writes: The cryptic press release NASA made last week that set the blogosphere afire with conjecture, which announced: "NASA will hold a news conference at 2 p.m. EST on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life." may be a case of "go fever" science pushed too quickly by press release. A scathing article in lists some very prominent microbiologists who say the NASA backed study is seriously flawed and that the finding may be based on something a simple as poor sample washing to remove phosphate contamination. One of the scientists, Shelley Copley of the University of Colorado said “This paper should not have been published,” while another, John Roth of UC-Davis says: "I suspect that NASA may be so desperate for a positive story that they didn't look for any serious advice from DNA or even microbiology people," The experience reminded some of another press conference NASA held in 1996. Scientists unveiled a meteorite from Mars in which they said there were microscopic fossils. A number of critics condemned the report (also published in Science) for making claims it couldn't back up.
