Engineers have invented a new kind of nano-particle that shines in different colors to tag molecules in biomedical tests. These tiny plastic nano-particles are stuffed with even tinier bits of electronics called quantum dots. Like little traffic lights, the particles glow brightly in red, yellow or green, so researchers can easily track molecules under a microscope. Full Story
