Wednesday Nite @ the Lab
Tamara Thomsen, a maritime archaeologist at the Wisconsin Historical Society, dives into the wreck of the largest wooden bulk carrier ever built, the Appomattox. The ship, listed on the National Register of Historic Places, lies on the bottom of Lake Michigan less than 200 feet off shore at Atwater Beach in the village of Shorewood, north of Milwaukee.
Dave Hart, a hydrogeologist with the Wisconsin Geological & Natural History Survey, takes us on a tour of the geothermal resources in Wisconsin.
Chris Hittinger, an assistant professor in the Department of Genetics at UW-Madison, discusses a recently discovered yeast in the Andean forests of Patagonia, Argentina. The yeast, Saccharomyces eubayanus, fused with a S. cerevisiae ale yeast and evolved into the modern lager yeast that brewers use around the world.
Ken Cameron, an associate professor in the Botany Department at UW-Madison and the director of the Wisconsin State Herbarium, presents an overview of the evolution, relationships, identity, and natural history of Vanilla orchids and other related orchids.
Nancy Keller, a professor of Medical Microbiology and Immunology at UW-Madison, introduces Aspergillus, a genus of fungi, well known to human kind due to the inclusion of harmful pathogens, industrial workhorses, food and beverage microbes and genetic models. This genus of fungus is known for its production of biologically active natural products that are either harmful or helpful to humankind.
Xudong Wang, an assistant professor in the Department of Materials Science and Engineering at the UW- Madison, talks about how the recent development of nanogenerators has demonstrated a promising solution for the design of self-sufficient implantable power source.
David Baum, a professor in the Department of Botany at UW-Madison, discusses Charles Darwin’s concept of common ancestry related to the idea of the “The Tree of Life.” While biologists have accepted the validity of common ancestry for one hundred and fifty years, the full implications of the tree framework have only become clear in the last few decades.
Brent McCown, Professor Emeritus in the Department of Horticulture at UW-Madison, explores the current economic situation for cranberry growers and charts out the needs of the industry. He describes UW-Madison research collaborations with growers to discover and test new ways to grow cranberries better, as well as to find new genetic approaches to grow better cranberries.
David Blehert, PhD., Microbiologist at the USGS - National Wildlife Health Center, highlights the discovery and progression of the Bat White-Nose Syndrome in the United States. Blehert discusses the studies taking place at the NWHC to determine how the fungus is transmitted from an infected bat to a healthy bat.
Greg Richards, University of Illinois.
Greg Richards explains about organisms and the kind of stresses they encounter in
their environment, how RNA molecules work to help bacteria deal with stress, and how E. coli uses a small RNA to deal with toxicity associated with sugar phosphates.
