An anonymous reader writes "BBC news is reporting that:
"A new mineral matching its unique chemistry — as described in the film Superman Returns — has been identified in a mine in Serbia.
"Researchers from mining group Rio Tinto discovered the unusual mineral and enlisted the help of Dr Stanley when they could not match it with anything known previously to science.
"Once the London expert had unravelled the mineral's chemical make-up, he was shocked to discover this formula was already referenced in literature — albeit fictional literature.
'Towards the end of my research 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.'""
