Check out this cool technology.
From Reuters via MSNBC.com:
"After the bomb, which is like a balloon within a balloon, is injected into the bloodstream it travels to the tumor and burrows deep inside. The outer membrane then disintegrates and releases an anti-angiogenesis drug so the blood vessels feeding the tumor collapse."
The use (overuse) of the word bomb is telling of the current times. It's as though someone got reassigned from the Iraq war to the health section. Still, the study is very cool, and I love nanotechnology--let's give props to the little things in life.
