(Originally aired: June 17, 2017) Guest: Jane Joseph, PhD, Professor of Neuroscience, Medical University of South Carolina The world’s best rock climber, Alex Honnold, does free solo climbing. Meaning no net, no safety gear. Last June, he climbed the face of Yosemite’s El Capitan in less than four hours, with nothing but his fingers, his toes and a bag of chalk clipped to his belt.

What Facebook Does with All that Personal Data It Collects Mar 22, 201818m(Originally aired: March 14, 2017) Guest: Michal Kosinski, PhD, Assistant Professor of Organizational Behavior, Stanford University Let’s look now at some of the underlying science behind the current scandal involving UK-based Cambridge Analytica. The company got access to profile and preference data for some 50-million Americans through a personality quiz app that was available on Facebook and then used that information to try and sway the election for President Trump. The whole approach is based on work published in 2015 by psychologist and data scientist Michal Kosinski when he was a grad student at Cambridge University. Multiple reports indicate Cambridge Analytica approached Kosinski for help, but he declined and the firm turned to a different researcher at the university named Aleksandr Kogan
