'Nanodragster' races toward the future of molecular machines

Scientists in Texas are reporting the development of a "nanodragster" that may speed the course toward development of a new generation of futuristic molecular machines. The vehicle -- only 1/50,000th the width of a human hair - resembles a hot-rod in shape and can outperform previous nano-sized vehicles. Their report is in ACS' Organic Letters, a bi-weekly journal.
