Toward quantum computing, spintronic memory, better displays: Nuclear spins control current in plastic LED

Physicists read “spins” in hydrogen nuclei and used the data to control current in a cheap, plastic LED – at room temperature and without strong magnetic fields. The study brings physics a step closer to practical "spintronic" devices: superfast computers, more compact data storage and plastic or organic LEDs, more efficient than those used today in display screens for cell phones, computers and televisions.
