• Mathematician sees parallels between contagious diseases and mass shootings: There have been ten mass shootings this year, and plenty of talk about the factors that contribute to the high rate of these devastating events in the U.S. Research overwhelmingly points to gun availability as the biggest factor. But somewhere between 20 and 30 percent of mass shootings show signs of social contagion, that is of having been inspired by previous events. And, as with contagious diseases, researchers say early intervention is best. (Guest: Sherry Towers, Arizona State University)

The question is whether any of them can meet FDA's bar for approval and be used early enough to alter the course of Alzheimer’s disease.
