A new approach that "baits" the caps or telomeres could provide info on how rapidly we're aging and what we need to do to slow it down.

One enzyme plays a key role in how tumor cells replicate and divide indefinitely. Identifying the genes that give these cells their immortality could provide new drug targets to treat cancer.

The protective caps at the ends of chromosomes naturally shorten over time. Researchers found that direct damage can prematurely trigger senescence and contribute to age-related diseases like cancer.

Telomere shortening, long thought an unwanted side-effect of aging, actually protects against cancer in humans, a new study indicates.

Potential drug treatments are being developed for telomere diseases, in which cells age prematurely.

In their first year of residency, new doctors' DNA ages 6 times faster than normal, researchers find.
