You’ve probably seen http://hasthelargehadroncolliderdestroyedtheworldyet.com. But refreshing the page can get old after a while. So why not subscribe to the page’s feed?
(As I confessed to several friends last night, yes, I looked at the page’s HTML source. I am a geek.)
ETA: This is not to be confused with http://www.hasthelhcdestroyedtheearth.com, which doesn’t have a feed but does have more scientific information hidden in its HTML.
