  [ View the Video ] It's been long known that asbestos spells trouble for human cells. Scientists have seen cells stabbed with spiky, long asbestos fibers, and the image is gory: Part of the fiber is protruding from the cell, like a quivering arrow that's found its mark. But scientists had been unable to understand why cells would be interested in asbestos fibers and other materials at the nanoscale that are too long to be fully ingested. Now a group of researchers at Brown...

  Rice researchers power line-voltage light bulb with nanotube wire Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries, according to Rice University researchers. A Rice lab made such a cable from double-walled carbon nanotubes and powered a fluorescent light bulb at standard line voltage -- a true test of the novel material's ability to stake a claim in energy systems of the...

Polyurethane reinforced with carbon nanotubes outperforms currently used materials Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials. Marcio Loos, a post-doctoral researcher in the Department of Macromolecular Science and Engineering, works with...

DNA, a molecule famous for storing the genetic blueprints for all living things, can do other things as well. In a new paper,* researchers at the National Institute of Standards and Technology (NIST) describe how tailored single strands of DNA can be used to purify the highly desired "armchair" form of carbon nanotubes. Armchair-form single wall carbon nanotubes are needed to make "quantum wires" for low-loss, long distance electricity transmission and wiring. Single-wall carbon nanotubes are...

The Elsevier journal Reinforced Plastics reported that Zyvex Technologies' Piranha, a 54 ft unmanned boat built using carbon nanotube strengthened prepreg, has completed sea trials which demonstrate record fuel efficiency. Piranha is an unmanned surface vessel (USV) designed to enable a broad range of operations at sea with reduced operational costs and risks to sailors. The ground-breaking research that make such advances possible are reviewed in new and forthcoming books from Elsevier's...

Penn researchers have helped develop a nanotech device that combines carbon nanotubes with olfactory receptor proteins, the cell components in the nose that detect odors. Because olfactory receptors belong to a larger class of proteins that are involved in passing signals through the cell membrane, these devices could have applications beyond odor sensing, such as pharmaceutical research.  The research was led by professor A. T. Charlie Johnson, postdoctoral fellow Brett R. Goldsmith...
