We're not going to front like we understand exactly how it works, but two IBM researchers in California have announced that they've gotten closer to controlling the orientation and magnetic spin of individual iron atoms on a copper surface, which would have huge implications for nanotech storage -- imagine the basic tech in your hard drive shrunk down the molecular level.

As the iron travels through the air, the surface melts in rivulets that either vaporize or fall away in minuscule fragments, leaving a surface textured with grooves called regmaglypts.
