UW-Madison researcher Kristyn Masters and her team study heart valve disease and gender differences in the disease. By making models of the disease, they hope to test potential treatments. Reported by Jeffery Vinokur and edited by Steven Tooke and Corey Dome.
A biomedical engineer at the University of Wisconsin-Madison will receive a Point-of-Care Diagnostics grant through Grand Challenges in Global Health. Created by the Bill & Melinda Gates Foundation, the initiative seeks to engage creative minds across scientific disciplines—including those who have not traditionally taken part in health research—to work on solutions that could lead to breakthrough advances for those in the developing world. With his grant, David Beebe, a professor of biomedical engineering, will streamline methods for preparing patient samples such as blood and urine, among others, for point-of-care diagnostics in developing countries.
Neurologists who work to unlock the secrets of brain activity encounter what one might call the Las Vegas effect: "What happens in the brain, stays in the brain." The skull and dura mater are efficient insulators, keeping high-frequency electrical activity from leaving the brain. And between the blood-brain barrier and the brain’s aggressive immune system, nothing enters the brain without a fight—essential for staving off disease, but tough for medical interventions. This is the challenge for Biomedical Engineering Associate Professor Justin Williams. He and his students develop sensor technologies that capture stronger and more medically valuable signals from the brain, for use in therapies for stroke and epilepsy patients.
