Wrinkled skin and hair loss are unwelcome hallmarks of aging. But what if they could be reversed? Keshav Singh, Ph.D., and colleagues have done just that, in a mouse model developed at the University of Alabama at Birmingham. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible… Continue reading Using a Mouse Model, Scientists Reverse Age-Related Wrinkles and Hair Loss

Caffeine from Four Cups of Coffee Protects the Heart with the Help of Mitochondria
Java lovers, rejoice! A 2018 study has shown that caffeine promotes the movement of a regulatory protein into mitochondria in our cells, enhancing their function and protecting cardiovascular cells from damage. Caffeine consumption had already been associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying… Continue reading Caffeine from Four Cups of Coffee Protects the Heart with the Help of Mitochondria
Targeted Antioxidants May Help Fight Heart Disease
Older adults who take a novel antioxidant that specifically targets hostile cellular powerhouses, or mitochondria, see age-related vascular changes reverse by the equivalent of 15 to 20 years within six weeks, according to new research. The study, from experts at the University of Colorado Boulder, was published in the American Heart Association journal Hypertension. It… Continue reading Targeted Antioxidants May Help Fight Heart Disease
Cellular “Powerhouses” May Explain Health Effects of Stress
How does psychological stress translate into physical health effects? A key piece of the puzzle may be found in specialized cellular structures known as mitochondria, according to a pair of articles in the January issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the journal of the American Psychosomatic Society. The articles present an update on… Continue reading Cellular “Powerhouses” May Explain Health Effects of Stress
Interval Training Helps Stave off Old Age
It’s often repeated but true: Exercise keeps you healthy. It boosts your immune system, keeps the mind sharp, helps you sleep, maintains your muscle tone, and extends your healthy lifespan. Researchers have long suspected that the benefits of exercise extend down to the cellular level, but know relatively little about which exercises help cells rebuild… Continue reading Interval Training Helps Stave off Old Age
Turning Back the Aging Clock
A new approach that aims to reduce aging-related cellular damage has been developed by researchers from Caltech and UCLA. Led by Nikolay Kandul, senior postdoctoral scholar in biology and biological engineering in the laboratory of Professor of Biology Bruce Hay, the team developed a technique to remove mutated DNA from mitochondria, the small organelles that… Continue reading Turning Back the Aging Clock
Scientists Discover New Aging Pathway
Scientists have identified a new molecular pathway to aging, and they say that the process can be manipulated to revitalize old blood. According to a news release from the University of California Berkeley, the researchers found that blood stem cells’ ability to repair damage caused by inappropriate protein folding in the mitochondria, a cell’s energy… Continue reading Scientists Discover New Aging Pathway
Coenzyme Q10 Doesn’t Protect Against Free Radicals
The popular supplement Coenzyme Q10, widely believed to function as an antioxidant, is actually not likely to provide any benefits, according to scientists from McGill University. The discovery, by investigators from McGill’s Department of Biology, were published in Nature Communications. The lipid-like substance, found naturally in all cells, is believed to be an antioxidant (a… Continue reading Coenzyme Q10 Doesn’t Protect Against Free Radicals
