The caps at the end of our DNA, known as telomeres, shorten with each cell replication. For this reason, telomeres have been used as a marker of aging. But researchers, writing in the journal Scientific Reports, have discovered one animal whose telomere length increases with age — the edible dormouse.

There are 50,000 people over 100 years of age in Japan. Until recently, they got a special present for reaching that milestone.

When you go to the doctor you may get an eye test or a hearing test — but you never get a smell test. A new study from researchers at the University of Chicago may change that.

Would a similar thing ever work in humans? It’s too soon to say, really, but scientists are working on it.When researchers gave old mice the blood of young mice, it seemed to kickstart their brains, boosting their ability to learn and remember, and strengthening their muscles.

Immortality has always been a dream of humanity. Pulitzer Prize-winning science writer Jonathan Weiner examines the science of longevity in his new book, ‘Long for This World: The Strange Science of Immortality.’
