    By Alice Klein Rats seem to find driving relaxingKelly Lambert/University of Richmond Rats have mastered the art of driving a tiny car, suggesting their brains are more flexible than we thought. The finding could be used to understand how learning new skills relieves stress and how neurological and psychiatric conditions affect mental capabilities. We know…
