Previous, well-publicized research had shown that restricting calories can increase the life span of creatures ranging from fruit flies to dogs, for reasons still unclear. But the latest trial, led by geriatrics expert Richard Weindruch at the Wisconsin National Primate Research Center and published in Science, is the first to show that caloric restriction can improve survival in primates.
This kind of research takes enormous patience. Weindruch has spent 20 years studying his ...
