As reported by Fast Company, last Wednesday the FDA gave medical device clearance to a product called Traumagel that's designed to prevent bleeding and is basically a real-life version of Halo's Biofoam. Only instead of coming in a camo-green cylindrical canister, it comes in a stimpak-looking plastic dispenser, "a 30-ml syringe of an algae- and fungi-based hemostatic gel that's the color and texture of hummus."
Traumagel is designed for the kind of severe bleeding that follows a bullet wound, which would otherwise be treated with a product like QuickClot, a gauze that's soaked in a chemical clotting agent, or good old-fashioned superglue, like in that one episode of Poker Face.
