PITTSBURGH (KDKA) -- Without light, we can't have sight. We see objects because of how light interacts with those objects, our eyes pick up that light, and our brains interpret it. This seems rather ...

Not all monsters can be explained. In horror movies especially, it's often better to keep them partially obscured, or, in the case of The Invisible Man, encased in a technologically advanced suit that ...

Guy Bartal, from the light refraction lab at Berkeley, talks with Scott Simon about the research they're doing on "invisible cloaks." Bartal overseas research in this lab, and is a co-author of two ...

Berkeley -- Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

What are metamaterials and what can they do? The prefix meta (a Greek word meaning ‘beyond’) indicates that the characteristics of the material are beyond what we see in nature. Metamaterials are a ...

Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects ...
