On this week's Second Look, WMRA's Marguerite Gallorini explains some pretty complex science, and how researchers at the University of Virginia have recently discovered a link between the immune system (which fights off disease), and social behavior (especially disorders such as autism).... Also, we learned this week that more and more schools in Virginia are serving more and more breakfasts to students, so we revisit Jordy Yager's reporting on Food Insecurity in Virginia.
