DARPA is at it again. Though their homepage doesn't show it DARPA is simultaneously the most interesting and most scary part of America's armed forces.
As the name suggests "Defense Advanced Research Projects Agency" is about military applications of science. Previous projects include such illustrious successes as the Internet and the famous "gay bomb"
Their latest project (that we know of) seems to be a bio-engineered immortal organism.
Seriously!
Follow this link to The Wired.com article and check out the DARPA homepage lists of ongoing research programs. That's some scary stuff. - And remember that a large part of their activities is probably classified.
