POWER OF LIGHT  After implanting light-responsive motor neurons (green) into a mouse’s paralyzed thigh, researchers could activate leg muscles with a flash of blue light. 

Scientists can now control muscles with light. By combining advances from several fields, researchers created neurons that could be activated with light and implanted the cells onto damaged nerves in mice. A brief flash of blue light spurred formerly silent mouse muscles to life, scientists report in the April 4 Science.
