Remember that story about NASA having discovered bacteria using arsenic in place of phosphorous? UBC microbiologist Rosie Redfield ripped into the data underlying that conclusion on her blog RRResearch. (She’s also writing to the journal.) Redfield’s complaints and others prompted a lot of discussion about the the trouble with over-publicized science—see David Dobbs at Neuron Culture and Carl Zimmer on Slate, as well as Zimmer’s comprehensive roundup of scientific criticism of the study. Slate also took the opportunity to re-post an old piece on problems with peer review, but, as Chris Rowan wisely pointed out at Highly Allochthonous, peer review continues after a paper is published, especially in the case of “cutting edge” results like this one.
