  • Now we can see stroke damage in 3D. A technique that turns mouse brains transparent has given us the most detailed view yet of how stroke cuts off the blood supply in the brain. Now Dirk Hermann and Matthias Gunzer at the University of Duisburg-Essen in Germany and their team have developed a way to see all of a brain's blood vessels clearly, without having to slice it up. They injected a fluorescent gel into the hearts of mice, waited for it to be pumped around the body, and then removed the brains and soaked them in chemicals. "You're left with a brain that is clear like glass," says Hermann. The team looked at each brain under a microscope, lighting up the fluorescent gel using a laser.
