Get out tissues and stock up on antihistamines, cold season is starting. But while most of us try to avoid catching colds, science writer JENNIFER ACKERMAN volunteered to be infected with a cold virus while researching her new book Ah-CHOO!: The Uncommon Life of Your Common Cold. Ackerman sits down with Marty to explain the science behind colds – how they’re really spread, why some people are more susceptible than others, and what the best remedies are – chicken soup or cold medication? Ackerman is a senior fellow at Tisch College of Citizenship and Public Service at Tufts University.
