Carjackers doomed to die in petty theft gone horribly wrong

Two days ago, a truck carrying a container of radioactive cobalt-60 (enough to make a dirty bomb) was stolen by carjackers off a highway near Tijuana. Today, authorities found the truck. The thieves probably aren't terrorists, just some guys who wanted a truck with a crane attached to it. But, at some point, they opened the container of cobalt-60 and will now almost certainly die from radiation exposure. Maggie 91

Oceans could yield new sources of rare earth elements

Rare earth elements aren't actually rare, but right now the vast majority of them (97%) come from a single place — China. Given how important these elements are to the making of everything from computers to cars, that gives China quite the monopoly. With that context, here's the news: Japan just found a big supply of rare earth elements in mud at the bottom of the Pacific Ocean. Of course, what may be good news for manufacturing is not necessarily good news for the health of oceans. Maggie

A visit inside a vault holding $315,000,000,000 in gold bricks

The comic book periodic table of elements

University of Kentucky chemistry professors John P. Selegue and F. James Holler are collecting comic book references to chemical elements. On their Periodic Table of Comic Books site, you can click through the standard periodic table to see pages from comic books that mention specific elements. The samples seem to be weighted pretty heavily to classic, Golden and Silver Age stuff — there's a lot of 1940s Wonder Woman and miscellaneous anthology series from the 1960s.

They don't have all the elements accounted for yet. In particular, the lanthanides and actinides — aka, those two rows at the bottom where everything ends in "ium" — are lacking comic book shout-outs. Maybe you can help!
