An international team of physicists has theoretically predicted and experimentally generated light beams with a new property that they call the self-torque of light. The discovery, reported in the journal Science, could help us understand physics in binary black holes as well as how to control dynamics in molecules and nanostructures. Two time-delayed infrared vortex laser pulses (upper-left) impinge on a gas target to generate coherent, EUV light...
