The latest h+ magazine is a flash / PDF offering that contains a couple of short pieces that might be of interest for pro-longevity readers. Take a look at "Is Anti-Aging Medicine Coming to the Mainstream" and "Nanorobots in the Bloodstream," for example. The rest is of more general futurist interest this time around. "A microscopic-sized vessel injected into the bloodstream to destroy a lung tumor? [Researchers] have created such a vessel using live, swimming bacteria coupled to polymer beads. [They] have successfully steered these nanobots through the carotid artery of a living pig at 10 centimeters per second using magnetic resonance imaging (MRI). Their latest research shows they can do this with human blood vessels as well. The bacteria bots contain magnetic particles and swim using tiny corkscrew-like tails, or flagella. ... [researchers are] confident that a stealth seak-and-destroy mission could be completed against a tumor before the body's immune system wipes out the bacteria."
