Neuroscientists show 'jumping genes' may contribute to aging-related brain defects
As the body ages, the physical effects are notable; wrinkles in the skin appear, physical exertion becomes harder. But there are also less visible processes going on. Inside aging brains there is another phenomenon at work, ...
