A recent study, published in Science Advances and co-led by Rice University’s Pengcheng Dai, found that the material cerium magnesium hexalluminate (CeMgAl11O19) was not actually in a quantum spin liquid phase despite evidence suggesting it was. 

Researchers develop hybrid foam with a 3D-printed plastic skeleton—strong enough to save lives, light enough for everyday life.

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by independently engineering the intensity and polarization of light along the propagation direction. By encoding volumetric information into structured beam arrays, the system enables high-fidelity 3D reconstruction and a new physical-layer optical encryption strategy based on the depth and polarization keys. This compact technology opens promising opportunities for secure communication, optical storage, and next-generation 3D displays.
