Un-freakin' Believable

Get this... are you ready? Army scientists have developed a technique designed to regrow human body parts. Yep - new body parts. Apparently the scientists combined materials from the intestinal lining and the urinary bladder (yummy, right?) to create something called the "extracelluar matrix" (Sounds like a good sci fi title). When this substance is applied to a damaged body part, it boosts our natural ability to repair ourselves and voila - new body part. (or would that be, theoretical voila?)

One test subject had cut off the tip of his finger in a model plane propeller (...oh come on, we've all been there). The substance was applied to the finger continually for four weeks, and the finger started to repair itself. They didn't specify how advanced the repair was - but apparently it was enough to get them all excited.

Now I'm thinking, what if this doesn't have to be limited to only replacing what body parts we already had - but was expanded to give us extras? Who doesn't need a couple of extra arms these days? Four legs for faster running? Actual eyes in the backs of our heads.

Oh the possibilities are endless...
