Technology Research News July 16, 2003 Eric Smalley	Logic clicks with ratchet Microscopic electrical tornadoes pop up and skitter around superconductors whenever magnetic fields go through them. Scientists have found that manipulating these vortices, which can flip a bit between 1 and 0, could lead to very fast computer logic circuits.
Technology Research News July 16, 2003 Kimberly Patch	Electricity shapes nano plastic Plastic is a popular material for electronics these days because it's light and flexible. But today's chipmaking processes tend toward hard crystals, not soft polymers. A method that yields microscopic plastic structures could help, and it's based on a readily-available resource -- electricity.
Technology Research News July 16, 2003	Experience handed across Net Researchers have developed a method that enables one person to go through the exact movements of another, including feeling the same forces, over the Internet. The method could eventually be used to capture the touch of a musician, golfer or surgeon and pass it on to someone else.
Technology Research News July 16, 2003	3D display goes vertical Researchers from Seoul National University in Korea have devised a method that widens both the horizontal and vertical viewing angles of three-dimensional integral imaging systems, which use the clustered-lenses arrangement of insect eyes.
Technology Research News July 16, 2003	Gel yields nanotube plastic Researchers from Japan have found a way to distribute nanotubes evenly throughout a gel to form an electrically versatile material.
Technology Research News July 16, 2003	Nano toolbox gains carbon cones Researchers have come up with a useful twist on carbon nanotubes. Their nano pipettes grow thicker at one end to form microscopic cones that have central channels.
Technology Research News July 16, 2003	Jolts mix micro fluids Researchers from the New Jersey Institute of Technology have shown that it is possible to mix small amounts of liquids more quickly by pulsing the flow rates of the liquids through the channels in such a way that the pulse rates of the two liquids are out of phase.
Technology Research News July 16, 2003	Jet-laser tandem prints gold Researchers have found a way to print gold structures. The researchers suspended gold nanoparticles, which have a lower melting point then bulk gold, in a solution and used a modified ink-jet printer to print patterns of the solution onto a surface.
Popular Mechanics July 2003 Paul Eisenstein	World's Most Powerful Loudspeaker Want to hear the story about the world's loudest speaker? Because it is not always practical to launch a space shuttle when you need to create a loud noise -- to study airport sound control, for example -- Wyle Laboratories has developed a more compact solution, the WAS 3000.
CIO July 15, 2003 John Edwards	Sensitive Sensors Get those gigs. The State University of New York at Buffalo's Mechanical and Aerospace Engineering Department has developed sensors that could boost hard drive capacity by a factor of 1,000 -- without also driving up price.
