Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely small structure by scientists from the Faculty of Physics at the University of ...

Most solid materials we rely on, from steel, to plastics and ceramics, are designed to have specific properties. Whether a material is soft and flexible, or stiff and tough depends on how molecules ...
