Some Cool Science

A man recovered from a coma after his brain rewired itself. From the description in the article, it sounds like they tracked the neuronal connections with DTI--Diffusion Tensor Imaging. It's one of the hot research areas in MR right now; it acquires multiple images and causes them to have contrast that depends on the rate of diffusion in a specific direction. By doing some trickery, it can tell that direction of diffusion in the image.
