Believe it or not, many professional athletes, including MMA fighters, partake in yoga to improve their physical condition. Now scientists at The University of Edinburgh discovered that yoga for older adults helps maintaining better mental and physical health. Yoga […]

Aging-related inflammation can drive the decline of a critical structural protein called lamin-B1, which contributes to diminished immune function in the thymus, according to research from Carnegie’s Sibiao Yue, Xiaobin Zheng, and Yixian Zheng published in Aging Cell. Each of our cells is undergirded by a protein-based cellular skeleton. And […]

Advertising has a long history of targeting people with fantastic promises. From the perfect cream that will zap wrinkles before they even form to the workout gadget that will tone your entire body in 10 days, we are told of problems we didn’t know we had—and the solutions we need […]

The University of Washington in Seattle is among eight U.S. research sites undertaking a study to confirm whether brain imaging can detect signs of autism spectrum disorder in infants. The National Institute of Mental Health, part of the National Institutes of Health, is funding the multicenter research with a five-year, […]

In patients with chronic lymphocytic leukemia (CLL), the rate of disease growth varies widely. In a new study from the Dana-Farber Cancer Institute, the Broad Institute of MIT and Harvard, Massachusetts General Hospital and the University of Washington, scientists report that CLL growth is apt to follow one of three […]

Nearly 90 per cent of children with acute lymphoblastic leukemia (ALL) survive, yet the same treatments that save their life can adversely affect their quality of life and cardiorespiratory fitness health.  In fact, the cardiorespiratory fitness of ALL survivors can be significantly worse than a sample of healthy Canadians, despite […]

A multicenter research team led jointly by Washington University School of Medicine in St. Louis and the University of North Carolina at Chapel Hill has received a five-year, $9.5 million grant to further evaluate whether brain imaging can help detect very high risk of autism spectrum disorder in early infancy. […]

Tumors arise when cells shake off their restraints and start to multiply out of control. But how fast a tumor grows does not depend solely on how quickly the cancer cells can divide, a new study has found. By examining brain tumors in mice, researchers at Washington University School of […]

Your heart procedure was a success, and cardiac rehabilitation is going strong. That, of course, is great news. But there’s more to do to keep your mind and body healthy in the long run, says Susan Ryskamp, a dietitian at the University of Michigan Frankel Cardiovascular Center. One key factor: food. […]

DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don’t persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, researchers have designed DNA nanostructures that can heal themselves in serum. […]

Are some flavors of vape liquid more harmful than others? A UA scientist says yes, based on the results of a novel research project that used stem cells to study the effects of vaping on endothelial cells. Your favorite vape flavor may be more harmful than the nicotine itself. Using […]
