John Eischeid at Scientific American: Injectable Foam Blocks Internal Bleeding on the Battlefield

Despite their best efforts to stabilize abdominal wounds sustained on the battlefield, military first-responders have few options when it comes to stanching internal bleeding caused by, for example, gunshots or explosive fragments. The Defense Advanced Research Projects Agency (DARPA) says it is studying a new type of injectable foam that molds to organs and slows hemorrhaging. This could provide field medics with a way to buy more time for soldiers en route to medical treatment facilities.
