Kryptonite Discovered here on Earth
 

No Joke its true, seems some scientists discovered it really exists. Its white, not green, doesn't glow, and we can't test it out for sapping the strength of supermen quite yet.

Kryptonite is no longer just the stuff of fiction feared by caped superheroes.
A new mineral matching its unique chemistry - as described in the film Superman Returns - has been identified in a mine in Serbia.
