A geologist from London’s Natural History Museum found a mineral in Serbia he’d never seen before. While searching the Internet for its chemical formula — sodium lithium boron silicate hydroxide — he discovered that it’s the scientific name written on a case of rock containing kryptonite stolen by Lex Luther from a museum in the film Superman Returns. True it doesn’t have large green crystals like in the comics but is rather white and powdery. And yes, they’ve officially named it Jadarite, even though it’s not green. But hey, it’s still kryptonite to us. The next thing you know they’ll find Bizarro World, Mr. Mxyzptlk will show up and ask to buy a vowel, and it will turn out that it is indeed okay to tug on Superman’s cape.
