Add another item to the list of things one can accomplish using graphene, the wonder material of the future: Clean drinking water. Graphene could cheaply and easily remove salt from seawater, potentially turning the oceans into a vast drinking supply for thirsty populations. With properly sized holes, graphene sheets may be able to serve as all-purpose filters.
Forget the gigantic Large Hadron Collider — how about a particle-accelerator-on-a-chip?
OK, so it can’t reach the energies produced at the LHC or Tevatron, but this is still pretty impressive. Engineers at a micro-electro mechanical systems conference last week unveiled this tiny cyclotron device, which can speed argon ions down a 5-millimeter accelerator track.

This maze of electrodes, known as a surface-electrode ion trap, brings us closer to building quantum computers—that is, computers that could manipulate the quantum-mechanical states of atoms to process data millions of times as fast as today's most powerful supercomputers do.
How do you keep the back of your iPod clean? Sandpaper and electricity

I think Apple sells fantastic objects that look like they came from the future. And apparently, in that future we all live in velvet rooms and have no fingers-there´s no other way to explain the ultra-shiny mirrored backside of my new iPod nano, which got scratched and grungy with fingerprints in exactly three seconds. So I gave it a nifty scuff shield and, while I was at it, my own logo, using a superthin layer of electroplated copper.
