Now THIS is cool!
Australian Scientists Create Regenerating Mice.

Australian scientists have created mice which can regenerate absolutely any tissue except for the tissues of the brain. Heart, lungs, entire limbs and joints -- you name it.

With all the terrible news out there, I thought it be neat to point out that there is still wonder in this world. Can you imagine where this can lead for humans?

Indescribably cool, that's what I say. (Although I should point out that the Incredible Hulk and Wolverine have been doing this in comics for decades!)
