Finely spun starch fibers woven into a bandage could dissolve on your skin and be absorbed by your body, eliminating the sting and hassle of ripping it off in one fast motion. Starch fibers could also be used to produce toilet paper, napkins and other biodegradable products, according to researchers at Penn State.
Bleeding out on the battlefield--far from the trauma wards and triage units that might save their lives--is a scenario that soldiers simply have to live with (and try like hell to avoid). But thanks to a nanoscale breakthrough at MIT, the chances of it happening could be significantly reduced. Researchers there have created a nanoscale coating that can stop bleeding nearly instantaneously using a clotting agent already found naturally in blood.
