This is not peer-reviewed science yet, it's a preprint on Arxiv. Anyone (more or less) can upload anything to Arxiv.

The paper is submitted but not accepted (passed review yet), in this you're right, but I think its a growing practice for reputable scientists (as well as nobodies) to post to Arxiv immediately after they've submitted to a 'top' journal.

Anyways, here's the lead authors page, for the curious: http://physics.ucsd.edu/~diventra/

I accept that Arxiv material is generally eventually published, and serves as a staging post for publishable material, however I was protesting to the idea that being on Arxiv in any way constitutes peer review.

I note that the lead author is a Physicist, which makes it even more suspect for me - Physics and Theoretical Computer Science share some of the same toolkit, but the tricks and corner cases in each case can be wildly different, meaning that even if someone is a world leader in one field, they can be a complete novice in another!
