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.

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.

Archaeology, Crime Fiction, and Science

Mary Anna Evans, Assistant Professor in the Department of Professional Writing at the University of Oklahoma, discusses the importance of focusing on facts to write an entertaining story. Evans uses archaeology, scientific methods and her life experiences to create historically accurate fiction.

Caring for Your Heart and Arteries

K. Craig Kent, Chair of the Department of Surgery; Mohamed Hamdan, Head of Cardiovascular Medicine; Richard Page, Chair of the Department of Medicine; Heather Johnson, Assistant Professor of Cardiovascular Medicine; and Lucian Lozonschi, Associate Professor of Cardiac Surgery at the UW School of Medicine and Public Health, follow Mr. and Mrs. Smith through their cardiac care.

Ethics, Society, and Advances in Brain Science

Judy Illes, Professor of Neurology at The University of British Columbia, explores the impact that advances in the treatment of the nervous system disorders has on society today and into the future. Illes focuses on consciousness disorders, spinal cord injuries and neuro-degenerative diseases.

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.

The Promise and Pitfalls of CRISPR

Kate O'Connor-Giles, Assistant Professor in the Laboratory of Genetics at UW-Madison, explores the implications of using CRISPR genome engineering technology. CRISPR can be used to edit DNA sequences to probe gene function, create disease resistant agricultural organisms and correct disease-causing mutations in humans.

Oak Ecosystem Ecology

Brad Hutnik, Forest Community Ecologist at WI Department of Natural Resources, explains how to determine if you have an oak-hickory woodland on your property. Hutnik identifies the kinds of plants and animals that depend on an oak-hickory woodland and discusses why they’re vanishing in southern Wisconsin.

Imaging Live Cells Under Viral Attack

Nathan Sherer, Assistant Professor at the McArdle Laboratory for Cancer Research, explores the advances in live cell imaging technologies, leading to a clearer understanding of how HIV-1 and other viruses attack human cells. This technology is being used to advance new antiviral strategies.

Oak Woodland Management

Kevin Schilling, La Crosse County Forester at the WI Department of Natural Resources, explains how to cultivate oak trees on your land. Schilling discusses best practices for oak regeneration and the value of setting goals to maintain good quality oak woodlands.
