Age-Related

A mineral-recruiting gel that rebuilds tooth enamel from saliva could change the future of dental treatment. To date, we don't have any way to effectively regenerate this all-important outer layer of our teeth that erodes as we age.

In a breakthrough for diagnostics, scientists have created an effective and easy test that identifies a heart failure biomarker in saliva, opening the door to more rapid and accessible life-saving medical interventions for this disease – and others.

Listening to or playing music later in life could do more than lift your spirits – it might also help keep your mind sharp. A large study has found that older adults who regularly engage with music have significantly lower rates of cognitive decline.

In a review of more than 200 clinical trials, scientists have identified which exercise offers the most benefits in relieving the symptoms of knee osteoarthritis. It's the most comprehensive look at physical activity in treating the condition yet.

What naked mole-rats lack in the looks department they make up for it in longevity, living healthily for nearly four decades. Now, scientists have found just how they repair their DNA – and it has the potential to be harnessed by humans to do the same.

A first-of-its-kind study has found that recognizing – and using – personal strengths is linked with better physical and psychological wellbeing and fewer mental-health challenges in adults with attention-deficit/hyperactivity disorder.

Friendships, community ties and family bonds may apply the brakes to cell aging, providing a simple way to invest in health in older age. In a new study, scientists find that social connections are tied to slower biological aging and less inflammation.

Scientists have taken the most detailed look yet at the biology of a record-breaking woman who lived 117 years and 168 days free of cancer, cardiovascular disease and dementia. And many things they discovered could help us achieve our own longevity.

Scientists have developed a new eyedrop that can ferry protective compounds all the way to the retina, paving the way for a less-invasive – and injection-free – method of managing sight-stealing diseases such as age-related macular degeneration.

An inexpensive, over-the-counter form of vitamin B3 cut new skin cancers by an average of 14% in a study of more than 33,000 people. Among those who began taking a daily dose after a first diagnosis, the risk of a repeat skin cancer fell by up to 54%.

A daily cocoa supplement appears to reduce age-related inflammation, according to the largest study of its kind. The findings support earlier evidence that flavanols from plants like cocoa may help protect the heart and even slow biological aging.

A new study has revealed how the brain uses the night to flood the body with pulses of growth hormone to repair muscles, strengthen bones and balance metabolism. And why cutting corners on sleep undermines your physical health short- and long-term.
