A simple writing task may offer clues about aging brains. Researchers found that dictation, in particular, exposed subtle differences linked to cognitive impairment. Handwriting depends on both fine motor skills and complex mental processes, including selecting, organizing, and interpreting sensory information. Because writing places heavy demands on the brain, changes in handwriting may help reveal [...]

Scientists are discovering that some of the cells linked to aging may also be key to staying healthy. A growing body of research is changing how scientists view one of aging biology’s most studied cell types: senescent cells, often called “zombie cells.” While these cells have long been associated with aging and chronic disease, new [...]
