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 ...

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 ...

BUFFALO, N.Y. – We don’t often, if ever, associate babies with aging. They may have adorable wrinkles, but those aren’t the same as the ones frequently associated with, say, an octogenarian. But the ...

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 ...
