We're checking out the scientific mind meld that is the American Association for the Advancement of Science's annual meeting in San Diego this weekend. Pick up our Twitter stream @popsci (which also broadcasts every article we publish) and the hashtag #aaas10 to follow along for some amazing facts and probably one or two geek-isms. It is a giant scientist convention, after all.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
