Protesters Call on U.S. to “Liberate” Hong Kong Guest: Eric Hyer, PhD, Professor of Political Science, BYU There were more protests and clashes with police in Hong Kong over the weekend. These demonstrations have been going on since mid-June and they’re continuing, even though Hong Kong’s leader has withdrawn the extradition bill that sparked the protests in the first place. On Sunday, thousands protested outside the US Consulate in Hong Kong urging President Trump to “liberate” Hong Kong from Chinese control. Despite an Incredible History, The Future of Heart Disease Treatment Will Require Serious Work Guest: Dr. Haider Warraich, MD, Cardiologist and Clinical Researcher, Harvard University, Author of “State of the Heart” Just a generation ago, having a heart attack was an automatic death sentence. Today open heart surgery, pacemakers, stents and artificial valves make it possible for people with weak or damaged hearts to live long lives. Statins to prevent heart disease from cholesterol build-up are the most-prescribed medication in the country.  And yet, heart disease remains the leading cause of death in the US. And that’s true for both men and women. The hidden waterways beneath Greenland’s ice Guest: Kristin Poinar, Assistant Professor of Geophysics at the State University of New York At Buffalo Greenland is the world’s largest island –and it’s an autonomous territory of Denmark, which I only learned recently when President Trump started talking about wanting to buy it. But there’s some very serious news out of Greenland on the scientific front, related to how quickly the ice sheet that covers it is melting. Speedgate: New Sport Created by AI Guest: Whitney Jenkins, Creative Director, AKQA Artificial intelligence created a new sport called "Speedgate," and it's catching on around the world. The game is a mix between rugby, croquet, soccer, and ultimate frisbee. The sport's motto? "Face the ball to be the ball to be above the ball" - definitely sounds like something written by a computer.  What If All Our Digital Data Had Expiration Dates? The Case for More Forgetting Guest: Viktor Mayer-Schönberger, Professor of Internet Governance and Regulation, Oxford University, author of “Delete: The Virtue of Forgetting in the Digital Age” When was the last time you wished your memory was worse? I don’t think that’s even a thing. Mainly we’re just trying to keep a handle on the stuff we do need to remember. But Viktor Mayer-Schonberger thinks we’d be better off if we forgot more. Specifically, he argues that our digital memory needs a purge. Bringing Indigenous People’s Perspectives to National Parks Guest: Ed DesRosier, Founder of Sun Tours and Native Business Top 50 Entrepreneurs Honoree Glacier National Park in Montana is one of the few places in the country where you can take a bus tour with the stories and perspectives of indigenous people for whom the park has always been “home.” Glacier National Park is the ancestral home of the Blackfeet Nation. Huge swaths of it were once part of the tribe’s reservation, which shares a long border with the park. But the Blackfeet Nation has struggled to capitalize on the tourism dollars the park brings in. Ed DesRosiers was an early pioneer in that effort. He’s an enrolled member of the Blackfeet Nation and fought a long court battle to become one of the few indigenous people in the country licensed to operate a tour business in a national park.
