On today's Cool Science Radio, John Wells and Lynn Ware Peek's guests are Sophie Bushwick and Chris Cashwell. We start the show by discussing (01:36) why is it that for many of us cryptocurrency just seems so... cryptic?

Chris Cashwell of Azra A.I. joins the show to discuss one evolving AI technology first developed to track down terrorists post 9/11, then later expanded to help law enforcement combat human trafficking, and now to help cancer patients.
