Technology Research News August 27, 2003 Kimberly Patch	Email updates six degrees theory The venerable six-degrees-of-separation theory has been the key concept of many studies of networks like the Internet. An email-based update of the original experiment shows that one conclusion is off the mark. It turns out that the most well-connected people are not always the best contacts.
Technology Research News August 27, 2003 Eric Smalley	Cellophane turns LCDs 3D The same plastic wrap that makes your leftovers last longer turns out to be efficient at rotating the polarization of light by 90 degrees. This property is half of what it takes to make a three-dimensional display.
Technology Research News August 27, 2003	Detector senses single DNA Researchers from the University of California at Los Angeles have tapped differences in the folding characteristics of single-stranded and double-stranded DNA to make a sensor capable of detecting a single DNA molecule.
Technology Research News August 27, 2003	Crystal shortens infrared waves Researchers from Sandia National Laboratories have found a way to make a tungsten photonic crystal emit 1.5 micron lightwaves, which are in the near-infrared, or heat range. This makes it useful for thermal photovoltaic devices, which turn heat into electricity.
Technology Research News August 27, 2003	Tool sketches quantum circuits Researchers from Cambridge University in England and the Massachusetts Institute of Technology have developed a lithographic technique, dubbed erasable electrostatic lithography, that allows a quantum device to be drawn in a few hours rather than a couple of weeks.
Technology Research News August 27, 2003	Nanotubes spark gas detector Researchers from Rensselaer Polytechnic Institute have found a way to use carbon nanotubes to make very small, sensitive gas detectors.
Technology Research News August 27, 2003	Metal process makes heat chips Researchers from the California Institute of Technology have found a way to make tiny thermoelectric devices that can be used to generate electrical power from heat and to cool very small areas.
Technology Research News August 27, 2003	Light makes molecule shine Researchers from Kyushu University in Japan have constructed a fluorescent molecule that can be repeatedly switched on and off. If a way can be found to switch individual, closely-packed molecules on and off, fantastic amounts of information could be stored in very small spaces.
Inc. September 2003 Rod Kurtz	For-Your-Own-Good Innovation If you forgot to send in your car payment, look out. New devices are making the repo man look positively benign.
Inc. September 2003 Bobbie Gossage	Drives Provide New Electronics Avenue A Colorado company brings new circuitry to MP3 players near you.
