Neuroscientists Robert Moir and Rudolph Tanzi were sipping Coronas in separate offices during "attitude adjustment hour" at Massachusetts General Hospital, Harvard's largest teaching hospital. And, by chance, each scientist found himself wondering about an apparent link between Alzheimer's disease and the immune system.
