Breathless press reports notwithstanding, string theory is very far from being dead. If you're interested in what it is and what's going on within the field, I can recommend a new website called Why String Theory? (And of course, accompanying twitter feed @WhyStringTheory.) It was set up by Oxford undergraduates Charlotte Mason and Edward Hughes, working under Joseph Conlon. It's a very engaging and professional-looking site, featuring a great deal of explanatory material. Developing pedagogical sites like this is a great project for undergrads; the only looming issue is keeping the site going once the students move on to bigger and better things. Hopefully this one is kept up -- I think an initial surge of interest has already been taxing the poor web server.
