Geotimes October 2004 Megan Sever	Fuel Economies, Part I Although scientists are striving to have a mass-producible hydrogen fuel cell car in 10 to 15 years as well, the more realistic timeline is probably 50 years.
IEEE Spectrum October 2004 Steven Cherry	The Perils of Polling Twenty-five years in the making, electronic voting is finally being widely adopted in the United States. Unfortunately, recent evidence suggests that although we may be ready for electronic voting, the technology is not ready for us.
Wired October 2004 David Weinberger	Point. Shoot. Kiss It Good-Bye. No matter how good software becomes at identifying photos based on what you do with them, that's just the beginning. The higher goal is to get a machine to do what people do without thinking about it: analyze what's in the picture.
Reactive Reports Issue 40 David Bradley	A Golden Glow A new class of quantum dots made from small clusters of gold atoms is at the heart of fluorescing "artificial atoms" that could act as biological labels and nanoscale optoelectronics.
Reactive Reports Issue 40 David Bradley	That INChI Feeling Researchers have worked to develop a means for identifying chemical structures on a computer without having to work out a complex, standard nomenclature for each one.
Reactive Reports Issue 40 David Bradley	Lighting Up with Nanowires Semiconductor nanowires are beginning to emerge as rather versatile building blocks for creating photodetectors, LEDs and lasers
Technology Research News September 22, 2004 Kimberly Patch	Fuel Cell Converts Waste to Power One problem with fuel cells is that they produce carbon monoxide, which can gum up the works. Researchers have found a way to use the carbon monoxide to produce more energy in a reaction that can take place at room temperature.
Technology Research News September 22, 2004 Eric Smalley	Bank Transfer Demos Quantum Crypto As quantum cryptography nears practical application, researchers are working on the next generation of the technology, which includes the weird quantum phenomenon of entanglement.
Technology Research News September 22, 2004 Kimberly Patch	Agent Model Yields Leadership Developing teams of robots or software agents that have efficient collective behavior is an emerging field of research. One avenue involves letting agents receive advice from their acquaintances.
Technology Research News September 22, 2004 Eric Smalley	Flexible Sensors Make Robot Skin Researchers have devised pressure-sensor arrays that promise to give objects like rugs and robots the equivalent of one aspect of skin -- pressure sensitivity.
