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 ...

The model has the potential to transform the ability to study telomere biology, learn more about human aging, and ultimately help people preserve better health as they age.

As you age, it’s only natural to start logging slower mile times, no matter how fit you are. But don’t let this small decline get you down too much—there are still plenty of reasons to keep running as ...

A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of ...

To stay young, you have to keep your cells young, and what dictates a cell’s age is its DNA. Too many cycles of dividing can trigger the aging process, until eventually the cell peters out and stops ...

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 ...

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 ...

“Our study shows that nutrients and other factors that are commonly known to impact telomere length have little to no direct association with it” “Our study shows that nutrients and other factors that ...
