For generations, the inner character of a semiconductor was considered a fait accompli — sealed at the moment of manufacture, immutable for the life of the device. Researchers at the Institute of Science Tokyo have now quietly overturned that assumption, demonstrating that chirality, the handedness of molecules governing how electrons flow by spin, can be electrically switched on and off within a living material. The achievement, reaching 99 percent spin selectivity without a single magnet, suggests that the properties of matter need not be destiny — they can become a choice, revisable on dema
