Aging

In a massive study of 82,826 adults, bright artificial light in the evenings has been tied to age-related eye disease. At the extreme, light exposure was linked to a worrying increase in age-related macular degeneration, cataracts and glaucoma.

People taking fish-oil supplements in an effort to shield their brain from Alzheimer's disease might be better off investing that money in their diet, with a two-year study finding that omega-3 pills offer no protection from cognitive decline.

We may be on the cusp of understanding whether we can turn back time for our cells to stave off age-related disease, with the first human receiving experimental gene therapy as part of a landmark trial.

For many people, osteoporosis is only diagnosed following their first broken bone. Finding a cheap, accessible method for predicting this common bone-weakening condition early could help prevent serious fractures in more people around the world.

New research suggests that blood biomarkers in combination with self-reported memory concerns could offer an early clue to how Alzheimer’s disease develops across the life course, meaning midlife could be a critical window for promoting brain health.

Can spending more time engaging with the arts, such as visiting galleries, museums, singing, or painting, really lead to a longer and healthier life?

Less fat, animal-sourced protein and more complex carbs each day, for less than a month, can potentially take years off the biological clock in older adults. It suggests our health is more sensitive to short-term lifestyle changes than we think.

The use of blood-flow restriction cuffs that "hack" your physiology to speed up strength and muscle gains has been growing in popularity. However, researchers have now found that they come with a big downside during use – especially the older you get.

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.

A new study of exceptionally long-lived Rottweilers revealed that keeping their testes for longer may help them age more gracefully, offering fresh clues for how hormones shape frailty and resilience in both dogs and humans.

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.
