Wisconsin is a global leader in stem cell research. We learn what developments will be highlighted in this week's stem cell symposium here in the state. The executive producer of PBS's award-winning investigative journalism program FRONTLINE joins us to talk about the past and future of reporting that can take months or even years from start to finish. And why public broadcasting may be more important than ever. We also talk to an aviation attorney about airline passenger rights after a man was forcibly removed from a United flight, causing outrage.
