Researchers are moving closer to realizing the clinical potential of drugs that have previously been shown to support healthy aging in animals. In a review article published online in the Journal of the American Geriatrics Society, Mayo Clinic aging experts say that, if proven to be effective and safe in humans, these drugs could be “transformative”...

Reaction time variation may be a marker that predicts mortality in old age
A common indicator of neurobiological disturbance among the elderly may also be associated with mortality, according to a study published August 9, 2017 in the open access journal PLOS ONE by Nicole A. Kochan at the Centre for Healthy Brain Ageing (CHeBA), UNSW Sydney. Intraindividual reaction time variability (IIVRT), defined as an individual’s variation in reaction times...

Preparing for longevity—we don’t need to become frail as we age
Age-related frailty may be a treatable and preventable health problem, just like obesity, diabetes, and cardiovascular disease, highlights a review in Frontiers in Physiology. “Societies are not aware of frailty as an avoidable health problem and most people usually resign themselves to this condition,” says Jerzy Sacha, Head of the Catheterization Laboratory at the University Hospital in Opole,...

Cell aging in lung epithelial cells
Pulmonary fibrosis can possibly be attributed to a kind of cellular aging process, which is called senescence. This has been shown by researchers from the Helmholtz Zentrum München, partner in the German Center for Lung Research (DZL). As they report in the European Respiratory Journal, they have already successfully counteracted this mechanism in the cell culture...

Lutein may counter cognitive aging, study finds
Spinach and kale are favorites of those looking to stay physically fit, but they also could keep consumers cognitively fit, according to a new study from University of Illinois researchers. The study, which included 60 adults aged 25 to 45, found that middle-aged participants with higher levels of lutein – a nutrient found in green...

A tiny part of the brain appears to orchestrate the whole body’s aging
Why do we age? It’s a seemingly simple question that nonetheless scientists don’t have a great answer to. Some amount of aging seems to be controlled by our genetic makeup, while other evidence shows that our cells have an upper limit to how many times they can divide. But a new study points to a different player:...

Stem Cells May Be the Key to Staying Strong in Old Age
University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory that age-related muscle decline is primarily caused by loss of motor neurons. Study authors hope to develop a drug or...

Tick clock, stay ahead of the aging clock
Summary: Aging in humans (and animals) be either an inevitable process of wear and tear or as an inherent biological program by which the lifespan of each species is predetermined. Recent research has shown that DNA methylation, an epigenetic modification which alters how DNA is read and expressed without altering the underlying sequence, can show...

DNA-repairing drug could fight aging and radiation damage
An anti-aging compound could soon turn into a new drug that restores the body’s ability to repair DNA to its youthful condition Most of us accept that aging is inescapable, but maybe it doesn’t have to be. Researchers at Harvard Medical School and the University of New South Wales (UNSW) have uncovered one of...

A New Aging Discovery Could Allow Humans to Extend Their Lifespan
In Brief By observing the transparent cells of roundworms, researchers have uncovered a link between lifespan and the natural cellular process of RNA splicing. This research could lead to new breakthroughs in anti-aging treatments that would allow humans to indefinitely keep ourselves healthy, stalling death for as long as possible. Patterns in Splicing Though aging...
