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 ...

Researchers have developed a technology to invisibly transmit information disguised as background thermal radiation. Using a phenomenon called "negative light," they transferred 100 kilobits of data ...

Another one of my pet peeves is the fact that many people – civilians and scientists alike – use the phrase “negative reinforcement” to mean “punishment.” The two are not at all the same; in fact, ...
