In a paper in the journal Nature on Wednesday, the researchers reported that they had successfully built a working computer — albeit an extremely simple one — entirely from transistors fashioned from carbon nanotubes. The nanotubes, which are cylinder-shaped molecules, have long held the promise of allowing smaller, faster and lower-powered computing, though they have proved difficult to work with.
