Case Western research biologist James Watson nudges a cockroach onto an insect-sized treadmill, intending to measure the actions of its leg muscles with minute electrodes. To ensure that the roach runs on its course, Watson coaxes it onward with a pair of big tweezers. In the experiment, the electrode readings from the insect's leg are matched to its movements, recorded by a high-speed video camera. Cleveland, OH.
