The Zone

If this is real, then Superman should be, too! Scientists have found evidence that Kryptonite is real and present (for the lack of a better word) on Earth and that it has 'remarkable chemical similarities' to the fictional mineral.

Confirmed to be a totally new phenomenon by Brtish and Canadian scientists, the new substance, called Jadarite is not in the green crystallized form that we all learned to love, but its now in a white, powdered form.

Our only hope it that it isn't Tiberium (notice the similarities between Clark Kent's Kryptonite and Tiberium?)
