Protein gel staunches bleeding

This is a neat article on Scientific American: http://www.sciam.com/article.cfm?articleID=000D056A-AAFC-1526-AAB683414B7F0000

Basically, researchers have found a proten gel that rapidly stops bleeding with no observable side effects. It doesn't create or enhance clotting, but instead seems to just block the flow like a hair clog in a drain. Imagine the applications... for emergency workers, soldiers on a battlefield, or just home use when you cut your finger slicing carrots.
