Scientists have learned to compress light



The developers have modified their “super focus” tool to detect signals in the entire visible spectrum. The tool compresses the light from the tungsten lamp, and eventually the compressed light leaves the tip of the silver nanowire, whose radius is only 5 nanometers, in a conical path, like a beam of light from a flashlight. When the tip passes over an object, its effect on the shape and color of the beam is detected and recorded.
