Norbert K. Herzog, PhD and David W. Niesel, PhD
Medical Discovery News (pictured left to right)
The voices and energy behind Medical Discovery News are two scientists who met at the University of Texas at Austin in 1980, where they were pursuing research on infectious microbes and how they cause disease. Professors David W. Niesel, in 1983, and Norbert K. Herzog, in 1989, joined the faculty of the University of Texas Medical Branch at Galveston, world renowned for research in infectious and emerging tropical diseases, among other biomedical specialties. After accepting a Professorship in 2012 at the Department of Medical Sciences at the Frank H. Netter School of Medicine at Quinnipiac University in Hamden, CT, Dr. Herzog is now a founding member of the faculty at this new medical school. He continues as a Professor Emeritus in the Department of Pathology at the University of Texas Medical Branch.
Their outgoing personalities and passion for promoting the understanding of science among the public evolved into Medical Discovery News five years ago. The show’s two-minute conversations have unraveled breaking scientific news, such as whether airport full-body scanners pose radiation risks, as well as ancient history, such as King Tut’s paternity. They’ve also explained puzzling biomedical questions such as why people yawn and the health benefits of beer. Another episode on the link between too little sleep and early death really woke up their listeners! This is done in an entertaining and informative way. Watch out – you might learn something!

Director of Osher Lifelong Learning Institute
Dr. Michelle Sierpina, Founding Director of Osher Lifelong Learning Institute (OLLI) at UTMB Health in Galveston, Texas, began her work in eldercare in the 1960’s. Her Ph.D. with concentration in Humanistic Gerontology investigated the lived experience of lifestory writing and sharing groups. Her M. S. in Human Services Administration focused on management of non-profit organizations, especially adult daycare. At UTMB she developed The Pentimento Project—Lifestory Writing and Sharing Groups, a part of the Creativity Continuum: storytelling modalities across a continuum of capability including those with dementia.
A certified facilitator trainer for TimeSlips©, creative storytelling for those with dementia, she also serves on the national Scientific Advisory Council, Alzheimer’s Research and Prevention Foundation, Tucson, Arizona. Co-producer of Bringing Stories to Life and Making Lives Visible facilitator training videos, Sierpina is on the editorial Board, Osher Lifelong Learning Review— The Annual Journal of the Osher Lifelong Learning Institutes.
Under her direction, OLLI at UTMB has received three consecutive $100,000 annual grants from the Bernard Osher Foundation culminating in a $1 million endowment (with $50,000 bridge funding) in 2008. She has taught at UT Houston Center on Aging, University of Nevada, Reno, St. George’s Medical University in Grenada, and at conferences around the nation, as well as in UTMB’s Institute for the Medical Humanities and School of Nursing Graduate Program.
