Order from Chaos: Brownian Motion “Locks” the Spin of Photons in a Liquid

A study in Nature Materials from the Technion and China presents a new phenomenon in which light scattering from randomly moving nanoparticles creates measurable order – and may enable particle characterization and new optical methods.
