Reversing aging? Appearently scientists are getting ever closer to the foundation of youth. They may have found a way to reverse the aging process in muscles - if it works, I'll be able to open jars again without resorting to cheap tricks or modestly expensive kitchens tools. Researchers have found a key protein that affects the way the body recovers strength and flexibility. When injected into mice, the scientists limited loss of muscle mass and agility. The hope is that the treatment will eventually be transferable to humans.
