Technology Research News March 9, 2005	Avalanches up Disk Storage Researchers have constructed a spin-valve transistor that is more sensitive to microscopic magnetic fields than the devices that read today's commercial hard drives.
Scientific American February 28, 2005 Charles Q. Choi	Back to Square One After 15 years, cold fusion got a second chance at legitimacy from the U.S. Department of Energy, often seen by cold fusion advocates as their greatest enemy. History repeated itself, with a verdict that evidence remained inconclusive.
Science News February 26, 2005	Particle Physics Phun An array of games, such as Particle Pinball and Race for Energy, challenge visitors at a Web site hosted by the high-energy physics center known as the Fermi National Accelerator Laboratory.
Science News February 5, 2005	Nanotech Facts The National Nanotechnology Initiative has a Web site devoted to "Nanotech Facts."
BusinessWeek February 14, 2005 Baker & Aston	Why The Old Rules Don't Apply Nanotechnology: at this size, familiar materials can do things they couldn't do before.
BusinessWeek February 14, 2005 Stephen Baker	Nanotech's Heartland Lift Cleveland's Five Star Technologies, a materials manufacturer, is the kind of new company that's proving the Rust Belt can become part of the Next Big Thing.
Technology Research News January 26, 2005	The How It Works Files Nanotechnology: The laws of physics behave differently at very small scales. At the nanoscale, electrons travel more quickly through wires, transistors can mete out electrons one at a time, objects stick to each other, and light can bend matter.
Technology Research News January 26, 2005	Oil and Water Drive Display Researchers from Extreme Photonix and the University of Cincinnati have combined water and oil in a technology that promises bright, energy-efficient displays.
Technology Research News January 26, 2005	Chemical Fuse Makes Cheap Sensors Researchers in England have come up with a chemical fuse that includes a thin layer of material that changes when it is exposed to a gas. The change is enough to permanently disrupt a flow of electrical current through the film.
Technology Research News January 26, 2005	Metals Speed Clear Circuits Researchers have improved the performance of a new type of transparent transistor. The zinc tin oxide thin-film transistor is transparent, difficult to scratch, and conducts electricity an order of magnitude faster than previous efforts using the same class of material.
