Wired March 2005 Richard Martin	Mind Control Matt Nagle is paralyzed. He's also a pioneer in the new science of brain implants.
IEEE Spectrum February 2005 Alexander Hellemans	Strange Bedfellows Hybrid microcircuits, incorporating the desirable properties of the III-V compounds with those of cheap and ubiquitous silicon substrates, might soon find an important niche in electronics after all.
IEEE Spectrum February 2005 Erico Guizzo	IBM Reclaims Supercomputer Lead The new breed of supercomputers brings technology advances that may ultimately trickle down to a variety of high-performance computers, thus benefiting not only big-bucks buyers like the Energy Department and NASA but many other organizations in need of serious computing horsepower.
IEEE Spectrum February 2005 Tekla S. Perry	A Better Light Bulb? A titanium dioxide coating gives this light bulb the power to eat germs and odors.
Military & Aerospace Electronics February 2005 Adrian Carter	New technology advances applications for high-power fiber lasers Since introduced by Nufern as a standard product in late 2002, LMA fibers have enabled a power-scaling revolution, and have produced near-diffraction-limited beam quality at powers approaching 1 kW and slope efficiencies of around 75 percent.
Technology Research News February 23, 2005 Kimberly Patch	Humanoid robots walk naturally There's a reason most movie robots have wheels in place of legs or are powered by an embedded human. Making machines walk on two legs is exceedingly difficult.
Technology Research News February 23, 2005 Kimberly Patch	Springs simplify micromirror arrays Adaptive optics correct light waves that have been distorted, usually by the atmosphere, by bouncing them off a mirror that rapidly changes shape to produce clearer images or signals.
Technology Research News February 23, 2005	Process yields semiconductor foam Researchers from Wayne State University have made crystalline aerogels -- new semiconductor materials that are very porous, giving them very high surface areas.
Technology Research News February 23, 2005	Rod arrays focus sound Researchers from the Polytechnic University of Valencia in Spain have produced a pair of flat lenses that control soundwaves.
Technology Research News February 23, 2005	Metal atoms make silicon magnetic Devices made from magnetic semiconductors can make use of the spin of the electron in addition to its charge. These spintronics devices are potentially faster and consume less power than today' electronics.
