Spintronics: A New Spin on Computing

"A growing effort is underway among researchers to find a way to make spintronics, the manipulation of electrons' "spin" to do computing, practical. The promise is clear: spintronics could lead to computers that turn on instantly and electronics that use far less battery power, and also overcome the looming limits to Moore's Law."

Hmmm... I don't understand the science of this at all...
