Kryptonite Discovered!

From BCC News via Slashdot, some researchers have discovered a mineral in the mines in Serbia. Chemical analysis identifies this as sodium lithium boron silicate hydroxide, which is quite similar to the museum's label for kryptonite in the movie Superman Returns: "sodium lithium boron silicate hydroxide with fluorine".

It is not green and it doesn't emit a cool glow. Instead, it is white, powderful, and mostly harmless ("mostly" is the qualification for the statement, as it is harmless to human beings but maybe not to one man). In any case, there doesn't seem to be any use for it at the moment.

In any case, I suppose now researchers can go ahead and discover Superman.
