Self-assembling gel stops bleeding in seconds

Swab a clear liquid onto a gaping wound and watch the bleeding stop in seconds. An international team of researchers has accomplished just that in animals, using a solution of protein molecules that self-organise on the nanoscale into a biodegradable gel that stops bleeding. If the material works as well in humans, it could save thousands of lives and make surgery far easier in many cases, surgeons say.

First, I completely disagree with inhumane morons that test on animals. Second, anything that helps stop bleeding like this is amazing. Could prove to be a literal lifesaver.
