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 ...

Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, ...

Researchers at The University of Manchester’s National Graphene Institute have shown that electrons in ultra-clean graphene ...

Laboratory of Behavioral Ecology and Evolution at Seoul National University Light and foraging ants seem totally unrelated, but they have one thing in common: they travel along time-reducing paths.

It took two major expeditions charting the solar eclipse of 1919 to verify Albert Einstein’s weird prediction about gravity — that it distorts the path of light waves around stars and other ...
