From US News: A growing number of researchers are aiming to build nanodevices: circuits and structures measured in nanometers, or one billionth of a meter–the length of 10 hydrogen atoms lined up in a row. Nanodevices could form the heart of superdense computer chips, more efficient solar cells, and perhaps even tiny factories. And biology can help construct them. After all, life's molecules are masters at building nanomachines, from the molecular motors in muscle to the tiny cellular…
