Technology Research News December 31, 2003	Inside-out images secure screens Computer displays are not particularly secure. Anyone with a clear view can glean information by glancing at a screen. A researcher devised a screen that can only be seen by a user wearing special glasses.
Technology Research News December 31, 2003	Colors expand neural net Researchers from the University of Tokyo have worked out a way to form an especially fast optical neural network by tapping the wave nature of lightwaves rather than just the amplitude, or strength of a signal.
Technology Research News December 31, 2003	Micro fuel cell runs cool Researchers have made a tiny methane fuel cell that works at 60 degrees Celsius. They have also shown that the fuel cell can use high concentration methanol to increase its operating time.
Technology Research News December 31, 2003	Electroplating boosts solar cells While not yet ready for practical use, researchers find that including titania in solar cell dyes can increase efficiency.
Technology Research News December 31, 2003	Shape key to strong sensors Researchers have found a possible explanation for why a pair of semiconducting compounds -- mixes of silver and selenium or tellurium -- are strong magnetic sensors over a wide range of magnetic field strengths.
PC Magazine January 20, 2004 Brett Glass	Biometric Security Someday biometric systems may play an important role in securing all kinds of systems, but they're not foolproof yet.
PC Magazine December 24, 2003 Sebastian Rupley	Lilliputian Levitation It's a bird, it's a plane, it's--the world's smallest flying microrobot?
CIO December 15, 2003 Christopher Lindquist	Upright Data Storage The engineers charged with finding ever more clever ways to stuff extra bits into a given square inch of magnetic platter are beginning to encounter the physical limits of current techniques. New advances in Perpendicular Magnetic Recording technology, however, may continue the density trend.
CIO December 15, 2003 Michael Fitzgerald	Smart Systems - 2010 The process of evolution provides models for dealing with the complexity of advanced IT systems. You could think of studying the development of species over time -- or building models that replicate natural selection -- as a giant Google search for the species that thrives rather than falters.
Technology Research News December 17, 2003 Kimberly Patch	Device guards Net against viruses Ordinary computers have no chance of being able to monitor the huge volumes of traffic flowing through the Internet. Specialized hardware, however, can. A device is poised to serve as a network sentry, scanning the full contents of every packet for signs of viruses and the like.
