Can you power an entire dance club with dancing? The British are about to try. The Boston Globe unveils the science of the perfect nap. Even thinking about taking an afternoon siesta seems to improve your mood. Dear Presidential candidates: Why no love for economists? The finding of ice on Mars is announced on the Phoenix Lander's Twitter feed, with lots of unnecessary exclamation points. Game theory goes to Euro 2008: Should the Dutch have intentionally lost to Romania to screw over the Italians? (They didn't.) Finally, it's been a mixed week for bloggers: arrests are up, but the Associated Press decides to leave blogs alone for now. Note: No, the Boston Globe's nap-map didn't come from a blog. But it's cool anyway.
