Technology Research News February 23, 2005	Tiny transistors sniff chemicals Researchers from the University of Texas at Austin have found that the chemical sensing abilities of infinitesimally small transistors made from thin films of the organic crystal pentacene are quite different from those of larger transistors made from the same materials.
Technology Research News February 23, 2005	Plastic changes color in heat Researchers have engineered a plastic that loses its color when heated. It could eventually be used to produce relatively inexpensive temperature-based paint.
Technology Research News February 23, 2005	Light writes data in electrons Researchers developed a spin memory device that writes data as electron spins using lasers, stores the electrons in quantum dots, and reads spin information by applying a voltage to the quantum dots to generate photons.
InternetNews February 17, 2005 Michael Singer	Intel Beams Up Silicon The ability to build a laser from standard silicon could lead to inexpensive optical devices that move data inside and between computers.
Bio-IT World February 11, 2005 Salvatore Salamone	Strategic Insights: No Researcher Left Behind Many open-source and commercial diagnostic tools can probe a cluster's performance, but virtually all of these tools are designed for use by the experienced software developer. Now, a new crop of user-friendly cluster productivity tools targets the scientist/engineer.
IEEE Spectrum February 2005 Anatoly Zak	Russians Propose a New Space Shuttle Late last year, Russia's S.P. Korolev Rocket and Space Corporation Energia revealed detailed plans for a next-generation, reusable space orbiter, dubbed the Kliper. But will it fly?
Technology Research News February 9, 2005 Eric Smalley	Atomic scopes eye living tissue Researchers have used a scanning probe microscope to look at the structure of a butterfly's wing at a resolution of five nanometers -- just two and a half times the width of DNA molecule -- proving that it is possible to use these microscopes to analyze material from living systems.
Technology Research News February 9, 2005 Kimberly Patch	Brainwave interface goes 2D Researchers have shown that it is possible to use brainwaves picked up by electrodes attached to the outside of the scalp to move a cursor, not just along one axis, but around a computer screen. The method promises to enable people who are severely disabled to use a computer cursor.
Technology Research News February 9, 2005	All-silicon chip laser demoed Researchers from Intel have moved a step forward in the push to meld lasers and silicon chips, which could eventually be used in portable biological and chemical sensors, to amplify communications signals, and to convert light to different wavelengths.
Technology Research News February 9, 2005	Nanotubes crank out hydrogen Material made from titanium dioxide nanotubes that is 97% efficient at harvesting the ultraviolet portion of the sun's light and 6.8% efficient at extracting hydrogen from water for use as fuel could be ready for practical use in two to five years.
