These single-molecule vehicles measure just 4x3 nanometers and have four buckyball wheels connected to four independently rotating axles and a organic chemical chassis. The Rice team found that the nanocars moved about on a metal surface by rolling of the wheels in a direction perpendicular to the axles, rather than sliding about like a car on ice.

This is pretty amazing stuff. More evidence that everything we are used to is about to change.
