Segment A: WFPL's news staff discusses this week's news, including excerpts and analysis of President Barack Obama's visit to the Brent Spence bridge, and this morning's announcement that the Sherman-Minton Bridge will not need to be completely replaced.Segment B: Growing numbers of patients being treated for cancer aren't able to get the medicines they need. The FDA attributes drug shortages — which have tripled over the past six years — to many factors, including a lack of raw materials, and pharmaceutical companies' decisions to stop making older drugs (which can be less profitable). The Courier-Journal's Laura Ungar took a look at drug shortages in Louisville and joins us to talk about what she found out. Then we'll turn our attention to technology — for many, a frustrating field this week, when massively unpopular changes to Facebook and Netflix were announced. Will the ill will last, or are people just resistant to change? FastCompany's Neal Ungerleider joins us to explain the changes and the response.Segment C: Marc Maron interviews comedians in his podcast, WTF. Today we'll interview him — and see if he's found any answers to his show's titular question.
