Thanks to Efoundations, I see Elsevier has announced an Article 2.0 contest, in which programmers can create new value by harvesting data from 7500 XML-encoded scientific articles.  This is an exciting opportunity for web 2.0 programmers interested in science.

McDawg says he has four PLoS ONE t-shirts! He must be embarrassed to not have a PLoS Pathogens t-shirt, PLoS Messenger Bag, or PLoS Travel Mug. Support open access by becoming a Public Library of Science member and get the goodies. Or do it for free by posting one of these free signs on your door or website. PLoS ONE has been doing really well, with over 2000 papers published to date.

(Fig 1 at right) Janssen & Shadlen (2005), Nature Neuroscience found that monkey LIP neuron activity followed the subjective hazard function of an objective bimodal probability density function, which goes up, down, then up again.
