We dive into the gross side of science with Anna Rothschild, host of the PBS/NOVA series Gross Science! Anna tells us how a robot named Vomiting Larry helped scientists discover how to stop the spread of a potentially deadly sickness. Plus, fourth graders tell us what they think is gross, and we learn why talking about poop can be important for your health.
