If only treating diseases were as easy as wiping a hard drive. But that might not be far off: Microsoft’s currently testing a set of research computers that could be used to fight cancer. At the moment, they’re processing massive amounts of data related to cancer research and drugs. But researchers say their ultimate goal is to create cells with “living” computers that can be programmed to treat diseases. They believe it may be possible to set up a “smart” molecular system within a decade.
