Long-term low-calorie diet prevents age-related molecular changes

Scientists from Russia and the United States have looked at how the gene methylation process changes its behavior with age and how the amount of calories consumed affects these molecular changes. They found that the age-related ...

Cellular reprogramming reverses signs of aging

Graying hair, crow's feet, an injury that's taking longer to heal than when we were 20—faced with the unmistakable signs of aging, most of us have had a least one fantasy of turning back time. Now, scientists at the Salk ...

Epigenetic clock predicts life expectancy

UCLA geneticist Steve Horvath led a team of 65 scientists in seven countries to record age-related changes to human DNA, calculate biological age and estimate a person's lifespan. A higher biological age—regardless of chronological ...

Lifetime stress accelerates epigenetic aging

An important risk factor for accelerated aging and age-related diseases is excessive or chronic stress. Scientists at the Max Planck Institute of Psychiatry in Munich have now found how psychological stress, which accumulates ...

Research links HIV to age-accelerating cellular changes

People undergoing treatment for HIV-1 have an increased risk for earlier onset of age-related illnesses such as some cancers, renal and kidney disease, frailty, osteoporosis and neurocognitive disease. But is it because of ...

Secrets of youth, based on prevention

Metabolites found in our blood are linked to ageing and can signpost the risk of developing age-related diseases. This may help avoid such risks and reduce the rate at which we age biologically.

Twins studies to identify the molecular cause of ageing

What makes us age biologically? We have always been intrigued by this question. Yet, it remains a fundamental research challenge. Now, the EU-funded project, EurHEALTHAgeing, aims to draw together studies of early development ...
