Holy crap! Geologists have recently discovered a new mineral in a remote part of Serbia which has been described as "sodium lithium boron silicate hydroxide". That is very similar to the name of the mineral "sodium lithium boron silicate hydroxide with fluorine" that Lex Luthor steals from the musuem in "Superman Returns". The scientists claim this is all a coincidence, and even had the audacity to name the new mineral "Jadarite" instead of what we all know is its real name - Kryptonite!
Now I don't know about you, but if the Kryptonians protect their trademarks as zealously as we do it's only a matter of time before a fleet of their galactic warships arrives overhead, disgorging thousands of troops, all of whom now feature super-human powers due to the presence of our yellow sun.
Of course, once we figure out how to mix this new mineral with fluorine, we'll be able cut them down like waves of Persians at Thermopylae! Kryptonite-flavored bullets, anyone?
