DNA created From molecular robot

Nanotechnology breakthroughs have been a common feature on Gizmag's pages throughout 2010, with everything from electronics, to solar energy and ... molecular scale robotics. In May, U.S. scientists announced the creation of a spider-like nanobot just 4 nanometers wide that can be programmed to start, walk, turn left, turn right, or stop, using single-strand DNA molecules. Descendants of the molecular nanobot, or “spider,” could someday be used to treat diseases such as cancer or diabetes.
