That's Joe Landolina pictured on the far left. He's a 20-year-old New York University student working toward an MS in Biomedical Engineering and Biomaterials, who amidst, you know...trying to get a degree, created a gel called "Veti-Gel" that instantly stops bleeding wounds and starts the healing process.
He explains his invention to the New York Post: "There's really no way to quickly stop bleeding except to hold lots of gauze on a wound. I thought if you could pour this gel into a wound, it would solidify and stop the bleeding."
Veti-Gel gets tested on a fresh pork loin in the YouTube video below. Warning: If blood makes you queasy, go ahead and skip this demonstration.
