Profiles James Heath, a professor at the University of California at Los Angeles (UCLA), who is researching molecular computing in partnership with Hewlett-Packard. His development of molecules called rotaxanes that behave like switches, just as transistors do; How he has developed a molecular memory circuit; His aspirations to build a rudimentary molecular computer; His work at Rice University in a team that discovered buckminsterfullerene, or buckyballs.

This article reports that a molecular piston has been spotted shuttling back and forth for the first time. The researchers behind the feat say the piston could be harnessed to drive future nanoscale machines or form part of a molecular memory. The piston works in conjunction with a synthetic organic molecule called a rotaxane. The molecular-scale machine made by chemist Fraser Stoddart at the University of California in Los Angeles, California, uses oxidation and reduction reactions to send the piston back and forth.

Reports that researchers at the University of California-Los Angeles have developed what they claim as the world's first nanovalve. Device's ability to control the flow of single molecules; Use of the molecular species rotaxane to develop the nanovalve; Application of the nanovalve in ultra-small chemical reactors and drug delivery systems.
