Challenges of Re-Using Rockets (Originally aired May 3, 2017)Oct 19, 201716mGuest: Phil Larson, Assistant Dean for Communications, Strategy, and Planning, University of Colorado Boulder Last week, a satellite launched into space aboard a special rocket built by SpaceX. What's special about the rocket is that it's reusable. About 7 minutes after it roared away from the launch pad at Cape Canaveral and released the satellite into orbit, the rocket came on home, touching down gently on a landing pad just off the coast. It's the twelfth time SpaceX has pulled off the feat of launching and landing a rocket. Up until just a few years ago, the rockets were for one-time use only. Which is a little like taking your car on a road trip and then sending it to the junkyard.

Women's Wear is Far from Fitting (Originally aired June 15, 2017)Oct 19, 201714mGuest: Anne Bissonnette, PhD, Associate Professor of Material Culture and Curatorship, Curator of Clothing and Textiles Collection, University of Alberta It’s just a fact of life that our bodies change in shape and size as we age. Sudden, or even subtle, shifts in weight can require a whole new wardrobe. Why are clothes in the Western world designed so that even a slight gain in the hips or belly requires a new pant size? On the other hand, the one-size-fits-all sari from India is proof that clothing can both fit and flex with the normal shifts in a body.

How Bitcoin Changes the World Economy (Originally aired June 21, 2017)Oct 19, 201722mGuest: Paul Vigna, Journalist, The Wall Street Journal, Author, "The Age of Cryptocurrency: How Bitcoin and the Blockchain Are Challenging the Global Economic Order" The next time you swipe your card at your local 7-Eleven, think about this: Before the money can leave your bank account and end up in 7-Eleven’s, there are at least five different organizations that will handle your credit card information. It’s an invisible bureaucracy of banks and finance companies and government agencies that set interest rates, charge fees, and control nearly everything about the way we use money. The electronic currency called bitcoin sidesteps all of that in a way that could save a lot of money. But bitcoin also has features that make it really attractive to drug dealers and hackers. So is bitcoin something to fear or embrace?
