Healthy aging

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.

For the first time, scientists have used innovative tech to demonstrated that a healthy microbiome needs a consistent flow of the right foods, finally proving that the "hunch" advice of 5 A Day is spot on, as far as your gut bugs are concerned.

Animal studies say rapamycin can slow aging – but does it work in humans? A new review finds the evidence for the off-label, low-dose use of the drug in healthy adults is thin, inconsistent, and far from conclusive.

Large weight swings or weight loss in later life aren’t just physical health risks, they’re tied to fast memory and cognitive decline, a new study has found. It underscores the importance of weight stability for brain health in older adults.

When we eat as we get older changes, but what impact this has on our health isn't well understood. New research, however, has found that in midlife and beyond, eating one particular meal later in the day is linked with a higher risk of early death.

A species loved by scientists has a new trick under its wings – a "time out" in youth that leads to significantly slower aging throughout life. This discovery, which shows that biological aging isn't fixed, is a breakthrough in human longevity science.

A specific amount of the trace element copper has been linked to protecting cognitive function in older adults, providing new insight into how the mineral aids the brain. It may even offer greater benefits to people recovering from stroke.

Scientists have found that bacteria on your tongue play a critical role in how nitrate-rich beets impact vascular health. However, that impact is not across the board, revealing a previously unknown link between aging, the oral microbiome and health.

The bitter taste receptors on our tongues are also found in the gut. A new study has identified two specific receptors in the large intestine that are associated with the aging process, which may help inform diet-based strategies for healthier aging.

Apparently, salmon sperm injections are the new big thing in anti-aging or rejuvenating facial treatments. Once the reaction to the treatment’s ingredients subsides, the obvious question is: Is there any science behind the celebrity-backed treatment?

Metformin, a first-line treatment for type 2 diabetes, has been associated with a 30% lower risk of death, according to a new study. The research adds to the growing body of evidence suggesting that the common drug may possess anti-aging properties.

In a new study, researchers identified a molecule produced by a particular type of brain cell that reversed the cognitive decline seen in both healthy aging and dementia. It provides a better understanding of aging and a potential treatment target.
