Kryptonite really exists!
Researchers of the Rio Tinto mining group have found that the mineral actually exists!
After its discovery, the researchers enlisted the help of Dr Chris Stanley, a mineralogist at London's Natural History Museum:
'Towards the end of my research,' says Dr Stanley, 'I searched the web using the mineral's chemical formula, sodium lithium boron silicate hydroxide , and was amazed to discover that same scientific name written on a case of rock containing kryptonite stolen by Lex Luther from a museum in the film Superman Returns'.
'The new mineral does not contain fluorine and is white rather than green, but in all other respects the chemistry matches that for the rock containing kryptonite. We will have to be careful with it - we wouldn't want to deprive Earth of its most famous superhero!'
Read reports here and here. Although kryptonite's discovery has only just been reported, I was impressed to see that Wikipedia had already been updated with the information:
In April of 2007, scientists found traces of a mineral matching the chemical composition of kryptonite, in a mine in Serbia. The mineral found does not contain fluorine and does not emit a green colour, instead it is white and emits a pinkish glow when exposed to ultraviolet rays. Nevertheless, the mineral is essentially kryptonite. It will formally have the name of Jadarite, named after the Serbian town where the mine is located. Most importantly, the mineral is harmless and has no known dangerous or toxic properties.
Now that kryptonite is no longer fictional, will I get to find my Superman?
