In a series of experiments, Weizmann Institute of Science scientists solved the puzzle of the relationship between electric current and the freezing temperature of supercooled water. Beyond the scientific interest, their findings may lead to the advancement of applications in diverse fields where control of ice formation is required

Applying a magnetic field to a non-uniform nanostructure. The measurement of the non-uniformity in the structure on the nanometer scale is performed by the optical spin Hall effect - measuring the spin splitting of the photons scattered from the structure using a "weak measurement". The spinners (blue and red) represent the two spin directions - the degree of spin of the scattered photons. (Image credit: Ella Maru Studio)

Researchers at the Technion have developed a technology that combines nano-optics and magnetism to diagnose nanometric non-uniformities in electronic chips and photons
