ScienceNOW: In the world of nanotechnology, few things get as much billing as nanotubes. Experts say that these cylinders composed of one-molecule-thin sheets could someday be used in everything from superstrong jet engines to cancer cures. Now researchers think they’ve found a way to make large amounts of an elusive type of nanotube that could provide even more impressive applications.
