Tiny computers go where no computer has gone before: "Tiny computers go where no computer has gone before
A major breakthrough in the use of molecules as information processors is to be announced at this year's BA Festival of Science in Dublin.
Nanotechnology experts are exploring the capabilities of molecules that act like conventional computers but can operate in tiny places where no silicon-based chip or semiconductor can go. Now, for the first time, they have used these molecules to perform logic operations and process information in spaces a few nanometres across. "
