Of all the things you wouldn’t associate with medicine, foam could one day save lives on the battlefield. The Pentagon has agreed to fund researchers developing a type of foam that is designed to stop internal bleeding in wounded soldiers. Arsenal Medical has received $15.5 million to continue developing its foam (still in pre-clinical stages), which works by injecting two liquids into the body that mix, expand and harden to create a temporary dressing. The foam can help control internal bleeding for up to an hour and be removed in minutes in one solid mass. If the foam tests successfully, it could help with up to 50 percent of survivable battlefield wounds. [Source]
