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 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 ...

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 ...

Like the plastic tip at the end of a shoelace, telomeres are stretches of DNA that cap the ends of chromosomes. Each time a cell divides, telomeres get shorter — a process that is part of natural ...
