Calorie restriction improves health, survival in rhesus monkeys
January 19, 2017
Studies show that most short-lived species, such as yeast cells, benefit from calorie-restricted diets. Could the same be true for species that live longer? Researchers in two parallel studies—one conducted by the National Institute on Aging...
Epigenetic age estimated by changes in DNA methylation predicts mortality
January 19, 2017
A person’s life expectancy is known to vary with chronological age, risk factors such as smoking, and health conditions such as heart disease. Add to that list a person’s “epigenetic age”—an estimate of biological age...

January 13, 2017
Mark your calendars April 6-7 for the upcoming Cognitive Aging Summit 2017 in Bethesda, Maryland. Researchers from across the country will gather to discuss promising areas of research into age-related brain and cognitive changes, with a special...
Harnessing gamma brain waves to clear Alzheimer’s proteins
December 29, 2016
Animal study tests novel way to influence Alzheimer's-related brain changes Gamma brain waves—electrical charges that help link and process information from all parts of the brain—are known to slow down in the brains of people with...
NIH awards aim to understand molecular changes during physical activity
December 13, 2016
The National Institutes of Health Common Fund announced today the first awards for the Molecular Transducers of Physical Activity in Humans Program, which will allow researchers to develop a comprehensive map of the molecular changes that occur in...
Adaptive brain network change supports healthy cognitive aging in rats
December 9, 2016
Why does our ability to remember fail as we age? Is age-related memory loss normal, or a sign of something worse, like Alzheimer’s disease? A new study in rats suggests that part of the answer may rest on how effectively different parts of the...
National study reports decreased dementia prevalence
December 5, 2016
Dementia prevalence among Americans age 65 and older decreased significantly between 2000 and 2012, according to a study published in JAMA Internal Medicine on November 21, 2016. Results from the nationally representative Health and Retirement Study...
Identifying brain networks that keep memory skills youthful in cognitive “superagers”
November 4, 2016
Older adults with above average memory skills for their age—so-called cognitive "superagers"—have distinct differences in brain networks compared to their cognitively normal peers. NIA-funded researchers identified two brain...

September 28, 2016
SAVE THE DATE – Thursday, October 20, 2016 The National Institute on Aging (NIA) at the National Institutes of Health is partnering with the Morehouse School of Medicine to convene a regional workshop. This will be an opportunity to discuss...
Identifying mechanisms that may keep memories sharp in the aging brain
September 23, 2016
New stem cells in the dentate gyrus section of the hippocampus—the brain structure responsible for memory and learning—grow and integrate with existing cells to make memories stronger and more precise. The new cells compete for space...
