Honey, I Shrunk the PC!

Scientists at the University of Arizona have discovered how to use quantum mechanics to turn molecules into working transistors in the lab, a breakthrough that might one day lead to high-powered computers the size of a postage stamp.

Results of the as-yet-unpublished study came together just weeks before Canadian researchers performed a similar feat using chemical means. That experiment appeared in the journal Nature last week. Together, the two studies could bring the final frontier in nanocomputing -- a single-molecule transistor -- considerably closer to reality.
