Geotimes June 2004 Megan Sever	The Infrasound Renaissance We are just at the christening stage of infrasound, where we were with seismic technology 30 years ago. This technology has endless possibilities for teaching us about the world.
Technology Research News June 16, 2004	Laser Tweezer Grabs Varied Specks Researchers have advanced the use of optical tweezers with a method that allows them to simultaneously trap and independently manipulate microscopic materials that have different indices of refraction.
BusinessWeek June 21, 2004 Larry Armstrong	Who's The Real Mr. Chips? The work of three scientists gave birth to transistors -- and to Silicon Valley.
Science News June 12, 2004	Light Projects This colorful, interactive Web site provides a lively introduction to the nature of light and spectra.
Technology Research News June 2, 2004 Eric Smalley	Atom-Photon Link Demoed Getting atoms and photons to exchange information is crucial for many quantum computer designs. The first verified atom-photon entanglement shows that it's not so hard to do, as long as you can accept a low success rate.
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	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	Photons Teleported Six Kilometers Real-life teleportation will never come close to the teleportation of fiction, but instantly sending single quantum particles like photons from one place to another has been proved possible in laboratory experiments and promises to extend the reach of quantum cryptography, which offers potentially perfect security.
Technology Research News April 21, 2004	Magnets Align Nanotubes in Resin Carbon nanotubes have great potential as components of new materials but aligning the tiny tubes can be tricky. Researchers from the Georgia Institute of Technology and Florida State University have developed a way to orient the nanotubes in a polymer mix using a magnetic field.
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.
