Back in January, we gave you a heads up about a new course available online: The Stanford Mini Med School. Now it's time for a quick update: the Stanford School of Medicine has launched a handsome web site that conveniently centralizes the video lectures in one place. 10 lectures (from the Fall term) now appear. Eventually, another 20 lectures will get posted. You can start watching here.
