This year’s Winter Olympics feature a new event called “skimo,” or ski mountaineering. The racing event involves periods of skiing uphill using “skins” for traction, sprinting uphill on foot, and a downhill ski slalom to the finish. Mountaineering historian Peter Hansen joins Host Flora Lichtman for an introduction to skimo, and the scientific connections of early modern mountaineers. 
Then, wildlife ecologist Kevin White describes the amazing capabilities of the mountain goat, what’s known about the physical features that contribute to their climbing ability, and risks to mountain goat populations.
Guests:
Dr. Peter Hansen is a professor of history at Worcester Polytechnic Institute, and author of the book The Summits of Modern Man: Mountaineering after the Enlightenment.
Dr. Kevin White is a wildlife ecologist based at the University of Alaska Southeast.

As ICE cracks down in Minneapolis and across the country, reporters and privacy advocates have drawn attention to how the agency is using technology: scanning people’s faces without consent, using private health records to make arrests, tracking people’s location in real time with phone data.
So how does all this work? How does the United States’ data ecosystem make it possible for not just ICE, but any number of government agencies and businesses to buy our private data? And what actually happens after we send that DM or open up Instagram at a protest to post a picture?
To learn more, Host Flora Lichtman sits down with law professor and tech policy expert Laura Moy. She’s testified in Congress about privacy laws and how data brokers profit off of personal data.
Guest: Laura Moy is an associate professor of law at Georgetown Law, based in Washington, D.C.

The new dietary guidelines from the USDA call for Americans to “eat real food” and consume less “highly processed” food. But how? By some estimates, ultraprocessed foods make up nearly 60% of the average American adult diet, and they’re all over school lunch menus.
Health policy expert Laura Schmidt and nutrition policy researcher Alyssa Moran join Host Flora Lichtman to talk about ultraprocessed foods and our food supply. What might they be doing to our health, and what steps could policymakers take to help Americans eat less of them? 

Guests:
Dr. Laura Schmidt is a professor at the Institute for Health Policy Studies at the University of California, San Francisco.
Dr. Alyssa Moran is deputy director of the Center for Food and Nutrition Policy at the University of Pennsylvania

In an effort to make their farms more environmentally and economically sustainable, some farmers are experimenting with agrivoltaics: growing crops underneath solar panels. This dual harvest is working for some, but what will it take for agrivoltaics to work on a larger, more industrial scale? 
Joining Host Ira Flatow are journalist Jana Rose Schleis and environmental economics expert Madhu Khanna.
Guests:
Jana Rose Schleis is a news producer at KBIA in Columbia, Missouri. Her podcast series, “The Next Harvest,” is available on podcast platforms.
Dr. Madhu Khanna is a professor of environmental economics and director of the Institute for Sustainability, Energy, and Environment at the University of Illinois Urbana-Champaign.

Point systems are everywhere. Ready for movie night? Consult Rotten Tomatoes. Vetting a new pediatrician? See how many stars they have. At work, it can be even more pervasive: There’s KPIs and ROIs because success has to be measurable.  
But what happens when we boil something down to one nice number? What do we lose? Philosopher C. Thi Nguyen, author of the new book The Score, joins Host Flora Lichtman to explore how metrics can be soul-crushing in work and in life, yet keeping score is freeing in the world of games. 
Read an excerpt from The Score: How to Stop Playing Somebody Else's Game.
Guest:
Dr. C. Thi Nguyen is a philosophy professor at the University of Utah in Salt Lake City. He’s the author of The Score: How to Stop Playing Somebody Else's Game.
