Nancy Morrow-Howell, PhD, is a national leader in gerontology, widely known for her work on productive and civic engagement of older adults. She is also the Bettie Bofinger Brown Distinguished Professor of Social Policy at the Brown School, faculty director of productive aging research at the  Center for Social Development and director of the Harvey A. Friedman Center for Aging, part of the Institute for Public Health, all at Washington University in St. Louis.

Researchers have identified the mechanism by which a specific sirtuin protein called Sirt1 (shown in green) operates in the brain to bring about a significant delay in aging and an increase in longevity.

For many older adults, the aging process seems to go hand-in-hand with an annoying increase in clumsiness. New research from Washington University in St. Louis suggests some of these reaching-and-grabbing difficulties may be caused by changes in the mental frame of reference that older adults use to visualize nearby objects.

Researchers at Washington University School of Medicine in St. Louis have restored normal blood sugar metabolism in diabetic mice using a compound the body makes naturally. The finding suggests that it may one day be possible for people to take the compound much like a daily vitamin as a way to treat or even prevent type 2 diabetes.
