It's Never Too Late for Exercise

A large study finds that regular exercise can help older people maintain their mobility and prevent disability. Mobility—being able to walk without help—is important for an older person's independence and health.

Researchers studied people in their 70s and 80s who were inactive. Half followed a program of walking and exercises to improve strength, balance, and flexibility. The other half took health education classes and did stretching exercises.

The study showed a structured exercise program can reduce the risk of disability in older people—and is the first study to do so. NIH's National Institute on Aging was the primary sponsor. NIA Director Richard J. Hodes, M.D., calls the findings gratifying. "These are actionable results that can be applied today to make a difference for many frail older people and their families," he says.

developing nerve cells

These developing mouse nerve cells have a nucleus (yellow) surrounded by a cell body, with long extensions called axons and thin branching structures called dendrites. Electrical signals travel from the axon of one cell to the dendrites of another.

A new exhibit gives people a unique look at life.

Life: Magnified is a collection of scientific images of blood, bacteria, viruses, and more, enlarged up to 50,000 times.

Scientists created the images for medical research. The colors come from chemical dyes and computer programs used to better see biology.

Life: Magnified is on display at Washington Dulles International Airport near Concourse C through November 2014. There's also an online version with images and longer captions. The images can be downloaded for free for educational, research, or news purposes. The gallery is available at

Three organizations co-sponsored the exhibit: NIH's National Institute of General Medical Sciences, the American Society for Cell Biology, and the Metropolitan Washington Airports Authority Arts Program.
