Technion scientists to an unexpected breakthrough when they became the first to observe the branching behavior of visible light. Shining a laser beam into a soap bubble, Technion President Uri Sivan and Distinguished Professor Moti Segev expected the light to lose its structure, but the light waves intensified and divided like the branches of a tree. The surprising results, featured on a recent cover of Nature, could be applied to medicine and might also further the understanding of how light flows through space and time.
