SCIENTISTS DEVELOP WORLD'S LONGEST ELECTRICALLY CONDUCTING NANOTUBES, October 18
Breakthrough discovery is 10 times longer than previous current-carrying nanotubes, paves way for supercomputer and health care applications.
UC Irvine today announced that scientists at The Henry Samueli School of Engineering have synthesized the world's longest electrically conducting nanotubes. These 0.4 cm nanotubes are 10 times longer than previously created electrically conducting nanotubes. The breakthrough discovery may lead to the development of extremely strong, lightweight materials and ultradense nano-memory arrays for extremely powerful computers, ultralow-loss power transmission lines, and nano-biosensors for use in health care applications.

A NANOWIRE WITH A SURPRISE, October 18
New research may advance the nanoelectronics field
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and their collaborators have discovered that a short, organic chain molecule with dimensions on the order of a nanometer (a billionth of a meter) conducts electrons in a surprising way: It regulates the electrons' speed erratically, without a predictable dependence on the length of the wire. This information may help scientists learn how to use nanowires to create components for a new class of tiny electronic circuits.

NEW DISCOVERY COULD HELP TOKAMAKS TO OPERATE CONTINUOUSLY, October 18
Nathaniel Fisch, a Princeton University professor and theoretical physicist at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has persevered in finding novel ways to use plasma waves to produce electric current. Plasma is a hot, ionized gas that serves as the fuel for nuclear fusion. Fisch's patient efforts led to his discovery of new ways of driving current by injecting radio waves into the plasma. These wave-induced currents can enable fusion reactors, called tokamaks, to operate continuously, which is necessary for an economical and practical fusion reactor.
