Age-Related

In a new study, researchers discovered that the human brain has four pivotal periods when it goes through marked changes, sparking five "epochs" that last for years. The adolescent phase, for example, was found to extend into our early 30s.

Our fat tissue could be used to make our bones regrow, with scientists successfully using adipose cells to repair spinal compression fractures. It could change how breaks are treated and improve bone strength in diseases such as osteoporosis.

Researchers have demonstrated how a secret weapon made in the gut, produced by consuming pomegranate and walnuts, can rejuvenate the immune system in middle age, shielding us from cell damage, inflammation and chronic diseases including cancer.

Boosting levels of a certain molecule that declines with age restored the function of hundreds of brain genes and reversed memory loss in Alzheimer’s disease models, fixing the RNA splicing errors that drive damage to critical neurons.

Caffeine appears to do the opposite of what you might think when it comes to the heart. Scientists have found that a cup of coffee a day actually protects the heart from atrial fibrillation – a condition that can lead to stroke and heart failure.

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.
