UrduScientists created a new metasurface that projects holograms and unique light patterns. This ultrathin material combines quasicrystals (ordered but not repeating structures) with light manipulation techniques. They achieved this dual function by arranging tiny structures and controlling light interaction. This paves the way for ultra-thin devices in holographic displays, anti-counterfeiting, 3D imaging, and even multi-substance detection tech.

Revealing the Thermal Heat Dance of Magnetic Domains
A collaboration led by scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, Helmholtz-Zentrum Berlin (HZB), the Massachusetts Institute of Technology (MIT), and the Max Born Institute (MBI) published a study in Nature in which they used a novel analysis technique—called coherent correlation imaging (CCI)—to image the evolution of magnetic domains in time and space without any previous knowledge. The scientists could not see the “dance of the domains” during the measurement but only afterward, when they used the recorded data to “rewind the tape.”
Using holograms to illuminate de Sitter space
The holographic principle is used to describe the expanding universe in de Sitter space. It provides a solution to Einstein’s general relativity equation with a positive cosmological constant. The proposed model uses a negative cosmological constant to account for gravity on anti-de Sitter space.
Mixed Reality Could Be the Future of High-Tech Coaching in Team Sports
Every pitcher believes he has enough gas for one more strike-out, but an invention from NJIT Associate Professor Tao Han might forever change that old stare-down between players and coaches on the mound.
