The hospital inside

Scientists at Kyoto University are developing microscopic devices that should someday eliminate the jabbing with needles, peeing in cups, and waiting around for test results that make hospital visits so uncomfortable. The Implantable Hospital Device will consist of micromachines that can monitor things like blood chemistry constantly and transmit the accumulated data via a wireless antenna to a hospital monitor. We hope they find time to develop a secure way of sending the data while they're at it, though; it wouldn't be much fun to have the state of your bodily fluids Bluesnarfed as you walk about.
