A number of studies have suggested that physically active men have lower rates of erectile dysfunction than couch potatoes, but all of them relied on people being honest about the amount they exercised. A new study published by the Journal of Sexual Medicine checked those results by measuring how much their subjects…
“I’m old” is the common refrain for why we get worse at athletics as we age. But here’s what’s really happening in the body through the years to make world-class performance less possible.
Human vaginas don’t have the fantastical loops and blind alleys of a duck vagina, but they still have some pretty amazing shape-changing powers. Here’s how they’re put together, and how that anatomy lets them grow when they need to.
Since the time of Darwin, evolutionary biologists have wondered why the lifespans of different species vary so significantly. A new model now suggests that the life expectancy of any given species is a function of evolutionary pressures — a conclusion that hints at the potential for powerful anti-aging interventions…
Another day, another mention of how staring at your smartphone is slowly withering you into an unrecognizable pile of sallow, sagging flesh. But I can assure you that "tech neck" is not the only smartphone-induced culprit of rapid aging. It's not just the phone that's going to send you to an early grave, but what's in…
Congrats to San Diego tortoiseshell Tiffany Two, who will turn 27 on March 13 ... making her the world's oldest living cat, according to Guinness World Records. That's 125 in human years.
Scientists from Stanford Medical Center have devised a technique for extending the length of human telomeres. It's a breakthrough that could eventually result in therapies to treat a host of age-related diseases, including heart disease and diabetes. It could also result in longer, healthier lives.
The antioxidant resveratrol, which is found in red wine and other foods like nuts and soy, is known for its ability to decrease incidence of heart disease and other illnesses, leading some to call it the "elixir of youth." Researchers at the Scripps Research Institute now have an explanation for how it works.
As the bulk of the global population gets progressively older, most of us worry about the potential problems it'll create. But a new study suggests that aging and the social changes that go along with it may introduce many positive benefits.
Researchers at the Salk Institute have discovered a toggle switch for aging cells. By controlling the growth of telomeres, it may eventually be possible to coax healthy cells to keep dividing and generating even in old age.
Not sleeping as well as you used to? Maybe it's just you're naturally getting older. Unfortunately, since sleep is so important for protecting your mind and body physically, it's a Catch-22.
A new paper in Cell shows a fascinating link between sensing pain and longevity. TRPV1, more commonly known as the capsaicin receptor, is expressed on our sensory neurons and is important for detecting pain and heat.
A handful of girls diagnosed as having 'Syndrome X' seem to defy one of the biggest certainties in life: aging. Scientists who are working to understand this rare condition say it could inform our efforts to radically extend the human lifespan.
A new study suggests it's all downhill after our mid-twenties. By comparing the performance of 3,305 StarCraft 2 players aged 16 to 44, researchers say we reach the peak of our cognitive motor performance at the age of 24. On the positive side, they say older plays can still find ways to compensate.
We're born, we grow, we age, and then we die. Well, maybe not all of us, according to a new study on the animals amongst us who, while they continue to grow older, don't deteriorate with age.
Some people age faster than others, but the discovery of a DNA body clock by UCLA researchers now shows that different parts of our bodies age faster than others. The discovery offers important insights into the aging process — and what we might be able to do about it.
Scientists have just discovered a chemical that prevents the death of brain tissue from neurodegenerative disease. The breakthrough is being called a "turning point" in the struggle to defeat a number of aged-related disorders, including Alzheimer's and Parkinson's.
A new five-year pilot study has shown that lifestyle changes, like an improved diet, exercise, and stress management, may help reverse aging processes at the cellular level. But as exciting as this finding is, we’re still far from the proverbial fountain of youth.
Stop what you're doing, set aside five minutes of your time and watch this from start to finish (no skipping around). It's stunning. Easily one of the best depictions of the aging process we've ever seen.
We still have two years before 2015, the year Back to the Future II revealed to us — including how stars Michael J. Fox, Lea Thompson and Thomas Wilson might age. How did the movie do in portraying their older selves? Turns out not too bad! Certainly more accurate than the public fax machines the movie imagined.
