During those periods when I'm posting regularly on science topics (it'll come back eventually, I promise!), PZ Myers' blog Pharyngula is a great source of fun biology-related stories. Moreover, it is a founding component of the Panda's Thumb group blog, which focuses on tracking and discrediting creationists and other breeds of evolutionophobe.
Next Wednesday PZ Myers will be giving the weekly Physics Colloquium; nothing too earth-shattering, just a quick rundown of the many reasons why Intelligent Design proponents are either lying or stupid. Come, bring your friends, and more importantly try to drag along those Maranantha Christian Fellowship wankers who keep using our lecture halls to host anti-science speakers. It'll be good for them, and fun to watch for the rest of us, since Dr. Myers long ago renounced the kid glove treatment.
