Technology Research News July 14, 2004 Eric Smalley	Teleport lifts quantum computing Researchers transported the states of charged atoms and showed that it is possible to do so on demand. The feat boosts the prospects for building quantum computers that employ trapped ions, quantum particles that live long enough to carry out multiple computations.
Technology Research News July 14, 2004 Kimberly Patch	Probabilities ease genetic logic Genetic algorithms are turning out to be useful for optimizing designs and solving problems. Researchers have devised a compact genetic algorithm that speeds the process by allowing a representation of the population as a whole to be passed back and forth rather than more voluminous information about individuals.
Technology Research News July 14, 2004	Ultraviolet powers pixels The technology could lead to a wide range of computer and television screens that are ten times more efficient than LCDs, according to the researchers.
Technology Research News July 14, 2004	Nanorods gain gold tips The rods and tetrapods could eventually serve as ultra-small transistors, memory elements, light-emitting elements and sensors in nanoelectronic and optoelectronic circuitry.
Technology Research News July 14, 2004	E-ink drawing pad closer to paper The device could eventually be used for freehand computer input, including cartoon drawing and adding annotation to documents.
Technology Research News July 14, 2004	Retinal display guides near-blind Researchers develop a wearable computer that helps people with low vision see potential obstacles. The system will become practical in three to five years.
Technology Research News July 14, 2004	Multi-projector system gets diverse This will enable large-scale projection in many more settings, including retail stores and outside building displays at night.
Technology Research News July 14, 2004	Laser tweezer traps nanotubes The researchers have showed that it is possible to pattern clusters of nanotubes into configurations that are likely to have near-term applications as chemical, biological and physical sensors.
Geotimes July 2004 Megan Sever	Next Best Friend: Cultured Diamonds Conventional thinking about diamonds may soon be changing. Diamonds -- long prized for their beauty, rarity and long generation times -- are now being created in a matter of hours in laboratories.
Popular Mechanics July 2004 Paul Eisenstein	Biggest Jet Engine The quest for speed, quiet and distance leads to bigger jet engines.
