Aging

An intriguing study is proposing an innovative method to treat age-related memory loss. The preclinical research shows memory decline in aging mice can be reversed by manipulating the composition of structures in the brain known as perineuronal nets.

An 11-year study has found that difficulty hearing speech in noisy environments may be an early sign of dementia. The next step will be to investigate whether treating mid-life hearing impairments can reduce the risk of dementia developing later on.

New research from the Stanford University School of Medicine and the Buck Institute for Research on Aging is demonstrating a new tool that can calculate a person’s immune system age, which could help predict frailty and disease before symptoms appear.

A great deal of research centers on restoring youthful plasticity to older brains as a way of tackling some effects of aging, and a team in Austria has now identified a pair of promising new approaches – ketamine and flickering light.

A new imaging study comparing brain activity of superagers to youthful brains highlights exactly how some older adults can maintain good memory function, and directs researchers to brain regions that could be stimulated to enhance memory in aging adults.

A new study has produced first-of-a-kind scientific evidence of the connection between stress and graying hair, identifying proteins that seem to drive this process while also demonstrating how it might even be reversed.

Scientists have uncovered some surprising news ways ultrasound can improve cognition in mouse models of Alzheimer's disease, something they believe could have wider implications for restoring cognition in the elderly.

Our health inevitably declines as we age, but maybe we can slow it down. A new study has found that boosting a certain gene in mice can increase their lifespan and keep them in better health for longer by mimicking the effects of caloric restriction.

Scientists at King's College London have used experiments in mice to demonstrate how fasting can also improve long-term memory and tackle age-related cognitive impairment, by boosting expression of what's known as the "longevity gene."

A study using epigenetic markers to track aging has found prematurely born boys seem to age faster than prematurely born girls. Why is unclear, but the research suggests the health of male preterm survivors should be closely monitored across their life.

Aging comes for us all – but perhaps the unpleasant symptoms don’t have to. In a new study, scientists have found a kind of anti-aging immunotherapy, reinvigorating immune cells to better clear out defunct cells that contribute to the aging process.

The most detailed genomic study ever conducted of individuals over the age of 100 years has homed in on several genetic traits that may protect from age-related disease. Gene variants improving DNA repair processes were particularly prominent.
