Not all sleep is equal when it comes to cleaning the brain
New research shows how the depth of sleep can impact our brain’s ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study reinforces and potentially explains the links between aging, sleep deprivation, and heightened risk for Alzheimer’s disease. “Sleep is critical to the function of the brain’s waste removal system and this study shows that the deeper the sleep the better,” said Maiken Nedergaard, M.D., D.M.Sc., co-director of the Center for Translational Neuromedicine at the University…

Lena Dunham is putting less pressure on herself and reaping the mental health benefits. The Girls star, 32, said that she spent too much of her life worrying about what people thought of her, and she decided to let go of that need. “I’ve spent a lot of time in this life feeling like too much.

According to a recent research, resistance training improves the health of over 65-year-olds, and the benefits occur even when some people train as little as once per week. The benefits show in improvements in blood values, muscle strength and mental well-being. “We found that individuals who were close to having high blood pressure, high cholesterol, high blood glucose, or high levels of inflammation improved the most after our 9-month training program. Training two or three times per week didn’t provide greater benefit in these individuals,” says Dr. Simon Walker of…
Read MoreIt’s not a shock: Better bandage promotes powerful healing
A new, low-cost wound dressing developed by University of Wisconsin-Madison engineers could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient’s own body motions to apply gentle electrical pulses at the site of an injury. In rodent tests, the dressings reduced healing times to a mere three days compared to nearly two weeks for the normal healing process. “We were surprised to see such a fast recovery rate,” says Xudong Wang, a professor of materials science and engineering at UW-Madison. “We suspected that…
