Cool New Spacesuits

ILC Dover LP, the company that manufactures spacesuits for NASA, is working on a spacesuit that would be able to heal punctures 2mm wide and smaller, alert the astronaut of holes larger than that, kill off bacteria automatically by slowly releasing silver ions, generate its own power by means of solar cells sewn directly onto the out layer of the suit, and block radiation using a polyethylene layer containing hydrogen. The company is still experimenting with exactly which of a number of options for materials they are going to use, but, in principle, they've already got all the things mentioned above working.
