A. Recent Progress in Nanotechnology to Benefit Consumers Within Five Years

Narrator: This is Science Today. Anyone who has shopped for a new cellular phone or laptop computer knows that smaller is better. Now researchers at the University of California, Berkeley are taking the shrinking trend even further with their work in nanotechnology. Dr. Peidong Yang says recent progress in the field could mean benefits for consumers within the next few years.

Yang: The immediate impact on society will be that we'll be able to make, of course, computers smaller, with higher speed; and also in terms of memory you'll be able to store more information.

Narrator: Nanotechnology deals with structures on a tiny scale. For example, a nanometer, the form of measurement Yang and his co-workers use in their work, is 250,000 times smaller than a human hair.

Yang: To be small, basically meaning you consume less energy, the footprint will be much smaller and also in terms of computers and communication, you have faster speed, big storage capability. So that will impact the daily life of the public.
