UW-Madison Spinoff Wants to Help Out in the Grocery Aisle
University of Wisconsin–Madison

When Wes Schroll moved from a dorm into an apartment and began grocery shopping, he hated it. “Every single one had the same issues,” he says. “I had no idea how much I'd spent until I checked out. Coupons were a pain in the butt, so I never used them. And the checkout was inefficient." Pointing to his smartphone, he adds, "I figured there had to be some way to utilize these pieces of technology that everyone has to streamline the process.”

Deadly Fish Virus Still Present in Wisconsin Lake
University of Wisconsin–Madison

In May 2007, hundreds of freshwater drum — also known as sheepshead — turned up dead in Lake Winnebago and nearby Little Lake Butte des Morts, both inland lakes near Oshkosh, Wisconsin. The fish were splotched with red and their eyes were swollen and bulging. The Wisconsin Department of Natural Resources (DNR) launched a quick response and, working with the Wisconsin Veterinary Diagnostic Laboratory (WVDL), quickly learned that a deadly virus was responsible: viral hemorrhagic septicemia virus, or VHSv.

An Ounce of Prevention: Research Advances on ‘Scourge’ of Transplant Wards
University of Wisconsin–Madison

The fungus Cryptococcus causes meningitis, a brain disease that kills about 1 million people each year. It’s difficult to treat because fungi are genetically quite similar to humans, so compounds that affect fungi tend to have toxic side effects for patients. Now, researchers at the University of Wisconsin-Madison have identified 18 proteins that play a role in spore formation and germination. The findings raises the possibility of preventing the disease by blocking the spores’ germination.
