(PhysOrg.com) -- By using light to change the elasticity of a DNA molecule, scientists have designed a molecular motor that can turn light into mechanical work. Unlike most previously reported molecular motors, the proposed setup involves an atomic force microscope, which acts as an interface with the outside world and enables the work to be extracted.
