Public Health Is a Utopian Vision (with Naseem Jamnia and Natasha O'Brown)

Public health is a vital part of keeping all of us safe — but what does it mean, and where did the concept come from? Special guest host Naseem Jamnia breaks it down for us, and tells us about some fantasy stories that show why public health is a collective concern. Plus we talk to scientist Natsaha O'Brown at Rutgers University about all the discoveries we've made lately about the blood-brain barrier.
