Walking is regarded to be an important form of physical activity for individuals belonging to all age groups. Several studies have linked walking with improved physical fitness and decreased risk of ...

Scientists investigate human telomere length to elucidate aging and diseases such as cancer and neurodegenerative disorders. In normal mammalian cells, a small telomeric DNA segment is lost after each ...

Scientists from Mass General Brigham explored the associations between telomere length—which decreases as a person ages or is exposed to unhealthy environments—and the risk for age-related brain ...

Results from the VITAL randomized controlled trial reveal that vitamin D supplementation helps maintain telomeres, protective caps at the ends of chromosomes that shorten during aging and are linked ...

Milan, Italy: A study of nearly 500,000 people has shown that smoking shortens the end fragments of chromosomes in the white blood cells of our immune systems. The length of these end fragments, ...
