Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

A new perspective article outlines a roadmap for harnessing light emission from individual molecules. By precisely controlling currents through a single molecule, researchers can generate light with ...
