Scientists in Germany have crafted “skyrmion bags” of light—complex vortex-like structures—on the surface of gold by cleverly manipulating how laser beams interact with nano-etched patterns. This unus ...

Energy scarcity is a central driver of animal behavior and evolution. The amazing diversity of life on this planet is a ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...
