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...
