The World's Smallest Car

Using the parts inside a single molecule, scientists have constructed the world's smallest car. It has a chassis, axles and a pivoting suspension. The wheels are buckyballs, spheres of pure carbon containing 60 atoms a piece.

It'd be a real squeeze to take it for a spin, however.

The whole car is no more than 4 nanometers across. That's slightly wider than a strand of DNA. A human hair is about 80,000 nanometers thick.

No Seats For Segways? There Are Now!

The new SegSeat, an easily installed accessory, returns many of the physically challenged to active lifestyles. Meter readers and security patrols will appreciate the feature as well.
