Still working on diagrams. . . Cairochemist, who has just recently started co-blogging at Skulls in the Stars, presents us a video showing hydrogen atoms migrating across a copper-palladium surface. Yes, understanding how catalysts work might help in arranging reactions for new energy sources, but even if it didn’t, being able to watch atoms move has a certain appeal of its own.

Oh, and Skulls in the Stars also points us to The Giant’s Shoulders, which we’re all hoping will become a new monthly event.
