Nanoscale Magnetic Processors
Gorgeous Si writes "Researchers in the University of Durham Nanoscale Magnetics Group are working on magnetic microchips. These new chips "could be 40,000x better than conventional chips while using 1,000,000 times less energy." I assume this actually means 40,000 times denser than conventional methods allow. Also worth lookig at for the pretty pictures. "
It seems their rendering of the letter R is weak, since SPHERES also contains a P instead of an R, and in both of those instances that P seems to have a small imperfection where the diagonal line of the R would join the arc.
