Wisconsin's Geoheritage

Kenneth Bradbury, State Geologist and Director at the WI Geological & Natural History Survey, UWEX, provides a geologic history of Wisconsin and highlights some of the outstanding geologic sites in the state. Bradbury discusses the work of the Wisconsin Geological and Natural History Survey.

Inequality of Opportunity in an Unequal Country

Tim Smeeding, Professor at the La Follette School of Public Affairs at UW-Madison, talks about social mobility, focusing on the advantages provided by the family you’re born into. Smeeding discusses whether less advantaged families have the same opportunities to move up and explores ways to address the inequality.

Are You Really Sleeping? Sleep and the Brain

Stephanie Jones, Assistant Director at the UW Center for Sleep and Consciousness, explains the benefits associated with getting enough sleep. Jones discusses the impact sleep has on brain health, brain development and disease.

The Science of Dairy Milk Harvesting

John Penry, PhD Student in the College of Agricultural and Life Sciences at UW-Madison, explains how milk is processed and ultimately made available for consumers at the supermarket. Penry compares dairy production in the U.S. to production in Australia and shares ongoing research into dairy milk harvesting at UW-Madison.

Early Noncommercial Radio in Wisconsin

Randall Davidson, Director of Radio Services at UW-Oshkosh, explores the beginnings of noncommercial radio in Wisconsin in the late 1920s and early 1930s. Davidson discusses the development of Wisconsin Public Radio stations 9XM, now WHA Radio in Madison, WPAH, now WLBL in Auburndale, and commercial station WHBY, originally broadcasting out of West De Pere.

Energy-Efficient Lighting and the Rebound Effect

Andrea Hicks, Assistant Professor of Civil and Environmental Engineering at UW-Madison, explores the history and societal benefits of artificial light. Hicks discusses trends in energy-efficiency lighting technology and their effect on energy savings.

Early Warnings of Big Changes in Ecosystems

Stephen Carpenter, Director of the Center for Limnology at UW-Madison, discusses how to predict ecological changes in lake, coral reef and ranchland ecosystems using time and spatial data. Changes in the resilience of the ecosystems can indicate a tipping point for a big change.

Design of Humane Animal-Handling Facilities

David Kammel, Livestock Housing Specialist at UW-Extension, discusses how to create a facility that provides a safe environment for cattle and for the people handling the animals. Kammel presents examples of facility systems that integrate fences, chutes and restraints.

Udder Anatomy and Physiology

Laura Hernandez, Assistant Professor in the Department of Dairy Science at UW-Madison, explains that the defining attribute of a mammal is that it has mammary glands. Hernandez uses cow udders to show how mammary glands work and she compares the nutritional make-up of milk from cows, goats, humans and other mammals.

De-Extinction: Resurrecting Extinct Species

Stanley Temple, Professor Emeritus of Forest and Wildlife Ecology at UW-Madison, discusses the use of biotechnology to slow the extinction of threatened species. Temple discusses whether the revival of a species is ethical and whether the de-extinction of a species is a scientific possibility.
