A team has re-engineered immune cells with a light-activated switch that modulates protein function and cellular behavior. When exposed to blue light, the cells change shape, infiltrating solid tumors ...

Engineers at Illinois' Northwestern University have developed the tiniest pacemaker you'll ever see. It's several times smaller than a regular pacemaker, and it's designed for patients several times ...

Scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development. Their optical system could guide the design of synthetic, light-activated cells for ...
