Nanowheels!!

Scientists have invented the molecular wheel. It is on now, nanotechnologically speaking. According to the article, this is one of many breakthroughs that will lead to the development of nanogears, which means a whole world of pre-industrial technology on a nanoscale. I'm talking nanocuckooclocks, nanoastrolabes, and nanopepper-mills. Get ready to never be the same again.
