The New York Times has thankfully started to link to sources and papers and actually does so in this article. Here is the paper: http://arxiv.org/abs/1104.0699

Links in the text are always a bit cryptic, it would help if they were to put an info box at the end of articles with all the relevant links — but I don't want to complain, putting the link in there at all is already a pretty masssive improvement.

Thanks. The link in the article was edited after my submission. When I posted the link was only to arxiv.org.
