Kirby talks with Bryan Walsh-he is the author of End Times: A Brief Guide to the End of the World. Previously, he was TIME's International Editor, its energy and environmental correspondent and was the Tokyo bureau chief in 2006 and 2007. James Comey comes up in conversation and Kirby talks about the shrinking Democratic field of candidates running for office.

Kirby guest this hour is Mary Eberstadt author of "Primal Screams"- a book that she hopes will spark conversations about identity politics, in This Day in History-Skynet became 'aware' and Max Nelson from the Freedom Foundation.

Kirby updates us on the story of Ryan George, a local musician who was viciously attacked after attending a show, stories of the day plus mental shortcuts that we all make in "Real Science with Dr. B".
