Growing Blood Vessels
DALLAS - Two kidney dialysis patients from Argentina have received the world's first blood vessels grown in a lab dish from snippets of their own skin, a promising step toward helping people with a variety of diseases. Doctors hope the technique someday will offer a new source of arteries and veins for diabetics with poor circulation and patients of heart bypass or dialysis.

Didn't even know that was possible. But it looks like science came up with something that will be very useful in the near future. I personally know of several people with diabetes and one that has lost a leg due to it. This could have prevented that.
