How long a person can stand — on one leg — is a more telltale measure of aging than changes in strength or gait, according to new Mayo Clinic research. The study appears today in the journal PLOS ONE.

Good balance, muscle strength and an efficient gait contribute to people’s independence and well-being as they age. How these factors change, and at what rate, can help clinicians develop programs to ensure healthy aging. Individually, people can train their balance without special equipment and work on maintaining it over time.

In this study, 40 healthy, independent people over 50 underwent walking, balance, grip strength and knee strength tests. Half of the participants were under 65; the other half were 65 and older.

In the balance tests, participants stood on force plates in...

AI-powered model using chest Xrays helps develop biomarkers for aging. Osaka Metropolitan University scientists have developed an AI model that accurately estimates a patient’s age, using chest radiographs of healthy individuals collected from multiple facilities...

Scientists have developed a method that can determine an organism’s biological age with unprecedented precision. Researchers expect new insights into how the environment, nutrition, and therapies influence the aging process.

Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an ‘aging clock’ that reads the biological age of an organism directly from its gene expression, the transcriptome...

Some people appear to be considerably younger or older than their chronological age. Genetic signatures that may help explain this have been discovered by scientists at the Salk Institute. The age-associated genetic patterns were found by analyzing skin cells from people of various ages, according to a study by Salk Institute scientists.

Researchers then applied the results to detect genetic signs of accelerated aging in people with progeria, a disease that causes patients to appear far older than their chronological age...
