Stefan vd Linden writes, "An international team of scientists has discovered a substance to heal bleeding wounds within seconds. They're using a solution of protein molecules that self-organizes into a biodegradable gel. Until now they've only tested it on animals, but the tests were highly successful. From the article: 'Some surgeons are already excited about the material. "I see great potential in the eye field, the gastro-intestinal field, and in neurosurgery," says Dimitri Azar, head of ophthalmology at the University of Illinois at Chicago, US. "In the eye, even a drop of blood will blur your vision for a long time," Azar adds. "A material that would stop the bleeding could lead to a paradigm shift in how we practice surgery in the eye."'"
