New transistor could cut 5% from world’s digital energy budget

Physicists at the University of Nebraska–Lincoln recently teamed up to craft the first magneto-electric transistor, a new spin on the transistor that could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet.
