In yet another development made just a couple of weeks ago, an important improvement in room temperature Spintronics was made; the great fundamental advantage is that it takes much much less energy to change the spin of an electron than to move an electric charge around. Up to now computer chips have not made use of a property of electrons every bit as fundamental as their charge, their spin.
