Lessons from the worm: How the elderly can live an active life

A team of researchers from the University of Michigan discovered that the loss of motor ability associated with aging begins in neurons and spreads to muscles. By stimulating neurons, they were able to reverse the decline in motor ability in roundworms and potentially develop a new treatment for human muscle decline.
