New research suggests that certain types of brain cells may be “picky eaters,” seeming to prefer one specific energy source over others. The finding has implications for understanding the cognitive decline seen in aging and degenerative diseases such as Alzheimer’s and multiple sclerosis.
Today, two-thirds of those ever reaching the age of 65 are on the planet. Further, university researchers may have the keys to help people live even longer, healthier and more productive lives — but is society ready?
Researchers at Washington University School of Medicine in St. Louis are studying whether fasting from food a few days a week provides some of the same health benefits as severely limiting calories every day of the week.
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.
Chancellor Mark S. Wrighton welcomed more than 60 scholars from around the world — including Washington University in St. Louis and representatives from the McDonnell International Scholars Academy partner institutions — to Seoul, South Korea, in June for the Global Aging Initiative. The meeting, sponsored by the Harvey A. Friedman Center for Aging at WUSTL’s Institute for Public Health, was the first opportunity for scholars to connect and identify opportunities for collaboration on cross-national aging-related research.
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.
Andrew Scharlach, PhD, the Eugene and Rose Kleiner Professor of Aging at the University of California, Berkeley, will deliver the 2013 Friedman lecture May 3 at the Eric P. Newman Education Center on the Washington University School of Medicine campus. The title of his lecture is “Creating Aging-Friendly Communities.”
A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease. Researchers at Washington University School of Medicine in St. Louis have found that age-related macular degeneration shares a common link with atherosclerosis. Both problems have the same underlying defect: the inability to remove a buildup of fat and cholesterol.
In the decades ahead, China will have a very large older population, with many older adults who are relatively healthy and interested in being actively engaged in their communities. Contributions of older adults will be necessary for social and economic development of families, communities and society. Peking University Press recently published Productive Aging in the World: Toward Evidence-Based Practice and Policy. The book is the result of a conference on productive aging in August 2011 at Peking University, co-organized by the Center for Social Development (CSD) at Washington University in St. Louis, Hong Kong Polytechnic University, and Peking University in Beijing.
Hundreds of mutations exist in leukemia cells at the time of diagnosis but nearly all occur randomly as a part of normal aging and are not related to cancer, new research at Washington University School of Medicine shows.
