Graphene, a new form of carbon discovered in 2004, seems to be taking the physics world by storm. I would take a bit of issue over the author's assertion that bucky balls and nanotubes have been non-starters. I read about various interesting practical applications involving them at least a few times a month. Still, this new stuff has pretty obvious implications in circuitry design, and that nearly always turns out well. Coming to a flat screen near you!
