When I last wrote about the research I did on aging and exercise, I focused on one of the major ways biologists can tell where a person is in the aging process: the epigenetic clock. I described a ...

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 ...

WHEN David Nurse turned 30, he wanted to find out how his biological age compared with his chronological one. A life coach with the US National Baseball Association, he hoped that the ultra-healthy ...

Studies have reported that telomeres consisting of repeated DNA sequences (TTAGGG) play an essential role in protecting the human chromosome ends from fusions and degradation. Replication of cells ...

MENLO PARK, Calif.--(BUSINESS WIRE)--Today marks the launch of TeloYears, a new genetic test that reveals the cellular age encoded in a person’s DNA. Now available from the company founded by the ...

New research suggests vitamin D may help slow biological aging by reducing telomeres shortening, a key marker of cellular aging. Newsweek has reached out to some of the study's authors as well as ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...
