Bigger may be better for televisions and football linemen, but nanotechnology researchers covet the tiny. They aim to build dainty computers and minute machines, such as this pair of molecular gears, that can improve manufacturing, cleanse polluted water, plumb clogged arteries, and even help us explore space. Immerse yourself in the ever-shrinking world of nanotechnology at this handy portal, which offers a links-rich introduction to the field, up-to-the-minute nano news, a list of the 12 best nanotechnology Web sites, and a fat glossary. You'll also find a rundown of corporate, government, and academic labs pursuing nanotechnology. For a glimpse into the nanofuture, read interviews with experts such as science writer Ed Regis or follow a link to a gallery of possible medical applications. Some day, for instance, dentists might be able to hang up their drills, instead dispatching squads of tiny machines the size of pinheads to patch cavities.
