I know it is just your opinion but I find the nature piece to be easily on par with the 'slate' coverage (and of course that's just my opinion ;) ). Nature typically does not go for spectacle, and the fact that they highlight the total lack of response to criticism from Wolfe et. al is quite telling. If you pick a forum to present your claim you should be willing to defend your claim in that forum. As far as I can see this will soon be a scientific career ruined not so much by doing bad science but by crawling under a rock to avoid the fall-out, it is my guess that if they could produce the evidence from mass spectrography after isolating the dna that they would have done so by now. That would conclusively put to rest a lot of the criticism.

  Could be my preference in writing style or familiarity with the author or both.

  I disagree with your assessment. There's no evidence of malfeasance, just poor judgment with regards to publicity and possibly some oversights in the lab. It wouldn't be reasonable to deeply fault the authors on a technical basis -- it's the job of peer review to catch mistakes before unfounded or embarrassing claims are made. I've seen disputes over conclusions unfold in two ways: 1. The party disputing the finding contacts the corresponding author with specific objections and suggests followup work that would meet those objections. If the objections appear substantive, the author('s lab) may then attempt to validate the finding. In the case I observed, the lab had fallen victim to a technical artifact. My PI suggested an approach for remedying the error. At the end of the process, he ended up co-authoring a retraction with the author. 2. Someone with specific objections writes to the publication. Generally the publication will give the author an opportunity to produce a rebuttal piece. This, on the other hand, resembles a slug match.

    Why should post-publication peer review be limited to working through Science. That will happen in due course (e.g. Rosie Redfield has already written a letter), but it is perfectly fine for scientists to dispute the paper via their blogs, etc. We live in an era where you do have to be ready for post-publication peer review, especially if you make far reaching claims and choose to do them in a very public manner

      I never claimed that it should be. I was just pointing out those cases that I am familiar with. What they did (press-conferences, etc.) was in poor form.

    > This, on the other hand, resembles a slug match. I think that is a direct consequence of how the initial findings were presented, it suggests that the peer review process was fast tracked in order to present these results as fast as possible and with as much fanfare as possible instead of going the slow and cautious route. I may be wrong about that but it certainly seems strange to read about this wide and far in the mainstream press before the results have been thoroughly vetted. It smacks of cold fusion all over again.

      Oh! I'm sorry for causing confusion. "This" referred to the example I was giving, rather than the situation at hand. I think that the NASA team is getting every bit they deserve. The only claim I dispute is the bit about their careers being ruined.

    3. Someone publishes research, holds a self-congratulatory press conference, ignores criticism. Eventually evidence is refuted and the scientist disgraced. See http://en.wikipedia.org/wiki/MMR_vaccine_controversy/ http://en.wikipedia.org/wiki/MMR_vaccine_controversy/ for an example.

  Nature typically does not go for spectacle Bwahaha, what led you to believe that? Check out "Genetic evidence for complex speciation of humans and chimpanzees" some time.
