Here’s a post from DNA researcher Rosie Redfield critically analyzing the paper that was released in Science and announced by NASA on Thursday regarding aresenic-tolerant bacteria in Mono Lake. I haven’t read the paper myself (I don’t have a Science subscription) and have been relying on news reports, but reading the review certainly casts doubt on the significance of these results. I suppose that we’ll have to wait for Science to publish her letter and for the authors to respond.

Razib Khan points to two more posts discussing the topic, which I’ll pass along. The first is a post by Alex Bradley which echos some of the concerns of Dr. Redfield and adds some insight of his own. The second is a critique of the media response to this story done by David Dobbs. Both are good reads that explain the situation nicely.
