These magnetic monopoles erase data

A physical particle postulated nearly 80 years ago could help provide a decisive step toward the realization of novel, highly efficient data storage devices.

Magnetic monopoles imaged for first time

Scientists have captured direct images of the long-theorized but never before seen magnetic monopoles. Monopoles - magnets which have just a single pole - were theoretically conceived by the British-Swiss physicist Paul Dirac, who showed in the 1930s that their existence is consistent with  quantum theory.
