CIO May 1, 2004 Martyn Williams	Voice Recognition Without the Voice Sensors record muscle twitches on researcher's face to demonstrate voiceless speech recognition.
InternetNews April 26, 2004 Michael Singer	IBM Takes Nano Chip Design for a 'Spin' A collaboration between IBM and Stanford University could lead to reconfigurable logic devices, room-temperature superconductors and quantum computers.
Technology Research News April 21, 2004 Kimberly Patch	Material Grabs More Sun Silicon solar cells capture only some of the spectrum of sunlight, limiting their efficiency. A mix of several metals and oxygen could lead to solar cells that capture much more sunlight. The key is misaligning the material's crystal structure by infusing it with oxygen atoms.
Technology Research News April 21, 2004 Kimberly Patch	Spoke Polarization Tightens Focus Conventional wisdom holds that you can't focus light much beyond half its wavelength, which has computer chipmakers scrambling to work out how to use extreme ultraviolet and x-rays to make smaller circuits. But scientists are coming up with tricks for getting around this not-so-fundamental limit.
Technology Research News April 21, 2004 Eric Smalley	Molecule Makes Electric Motor Researchers have built molecules that can spin on command, but finding a way to harness this molecular motion to carry out work is more difficult. A molecule that has a limited range of motion opens up new possibilities.
Technology Research News April 21, 2004 Eric Smalley	Optical Quantum Memory Designed Quantum computers that use photons rather than atoms or electrons are appealing because the equipment needed to handle them can be relatively simple. A scheme for trapping photons in fiber-optic loops and replacing the photons that the loops absorb could be the answer.
Technology Research News April 21, 2004	Printer Writes Micro 3D Objects University of Illinois researchers have come up with a new type of quick-setting three-dimensional ink that works a bit like a microscopic tube of toothpaste.
Technology Research News April 21, 2004	Tiny Rotors Spin Into Place Researchers from Northwestern University, ProChimia Poland in Poland, and Harvard University have devised a way to automatically configure tiny, rotor-based machines.
Technology Research News April 21, 2004	Nanotube Forms Drive Shaft A researcher from the Institute of Materials Research and Engineering in Singapore has fashioned a drive shaft that is 1,000 times narrower than a human hair. The component could someday be used in machines that are smaller than bacteria.
Technology Research News April 21, 2004	Sturdy Quantum Crypto Proposed Quantum cryptography systems promise potentially perfect security because it is impossible to eavesdrop on bits encoded in single photons without revealing the security breach.
