For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Veronica Then wore an electroencephalogram, or EEG, cap and stood in front of a black curtain with a white square placed behind her like a target. Studio lights beamed down from the ceiling as a panel ...

Researchers in Konstanz discovered a way to manipulate materials with light by exciting magnon pairs, reshaping their magnetic “fingerprint.” This allows non-thermal control of magnetic states and ...

Rainbows are optical phenomena resulting from the interaction of sunlight, water droplets, and the human visual system, not physical objects. Scientific understanding of rainbows developed over ...
