Brain tissue is an optical mess. Water, lipids, and tangled cellular membranes all bend light in different directions. If ...

Researchers at Politecnico di Milano and CNR-IFN have demonstrated all-optical logic operations in a tungsten disulfide (WS₂) monolayer at rates as high as 10 terahertz, according to a study published ...

A new autonomous laboratory recently navigated through billions of potential material synthesis recipes to identify brighter, ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

Nearly two centuries after Michael Faraday first showed that magnetism can twist light, physicists have uncovered a hidden magnetic ingredient inside this classic effect. The new work reveals that the ...
