Brain surgery is now done by lasers. But doctors must still open up the skull in an incredibly difficult procedure. Scientists are developing a transparent skull to make it easier. The transparent skull will serve as a window into the brain allowing immediate access to check the progress of cancer without repeated surgeries. It could take a decade before the see-through skull is perfected. Ross Reynolds talks with Masa Rao, assistant professor in mechanical engineering at the University of California Riverside who is working on the skull.
