Carl Zimmer reports: "Scientists see fatal flaws in the NASA study of arsenic-based life."
BTW, Science is a top-notch scientific journal. It's on par with Nature and PNAS.
Yet Science has published some clunkers over the years - e.g. the Schön scandal, the Hwang Woo-suk controversy, and the ALH84001 meteorite debate.
Now Science has published this "arsenic-based life" paper as well. If the paper likewise turns out to be a clunker like many microbiologists and other scientists already think it is, then the journal will have another lead balloon on its record.
I don't know how Science's track record compares to other prestigious scientific journals. But I can't imagine it's favorable at this point.
