Researchers observe branched flow of light for the first time

Researchers coupled a laser beam to a soap membrane, which contains random variations in membrane thickness. They discovered that when light propagates within the soap film, rather than being scattered, the light forms elongated branches, creating the branched flow phenomenon for light.

Laser takes pictures of electrons in crystals

Light microscopes cannot discern how electrons are distributed among atoms in solids. A new type of a light microscope, the Picoscope, that allows overcoming this limitation.
