Wired News: Scientists Breed a Tougher Mouse

Apparently, scientists have genetically modified mice to be able to run twice as far as normal mice before becoming exhausted. Also, they don't get fat as easy as normal mice. This is kind of scary to me, but I'm not sure why. I guess I'm sort of imagining if one of these mice escapes the lab and starts populating the entire world with Super Mice. There are also some pretty interesting ethical questions at the end of the article.

"The world is about to change dramatically" indeed.
