Technology Research News July 30, 2003 Eric Smalley	VR accommodates reality Virtual reality systems could use a bigger dose of reality to cure their tendency to leave users empty-handed. A system that makes real objects players in virtual environments creates a hands-on experience.
Technology Research News July 30, 2003 Kimberly Patch	Eyes off, screen off Giving computers the ability to discern where you are looking means, among other possibilities, setting screens to go dormant when they don't have your attention. The trick to making it practical is keeping the energy-saving mechanism from using more energy than it saves.
Technology Research News July 30, 2003 Eric Smalley	Chip senses trace DNA Handheld detectors could one day allow you to monitor your body for cancer, your water for chemicals, and your food for bacteria. This requires inexpensive electronics that are capable of detecting trace amounts of substances. One candidate is a chip containing DNA-tipped carbon nanotubes.
Technology Research News July 30, 2003	Laser bursts pierce fog Researchers in France have shown that it is possible to fire laser beams through otherwise impenetrable clouds, haze and fog. This means it could be possible to transmit data through these opaque media and remotely sense objects or chemicals within clouds, haze or fog.
Technology Research News July 30, 2003	Electricity loosens tiny bits Researchers have found a way to make flipping small bits easier. The electrically-assisted magnetization reversal process weakens the magnetization of a ferromagnetic semiconductor's magnetization by applying a pinpoint electric field, making the magnetization of individual bits easier to flip.
Technology Research News July 30, 2003	Nano light stores data in polymer Researchers from the University of Pisa in Italy have shown that it is possible to write lots of information in very little space using a thin film of polymer and polarized blue light.
Technology Research News July 30, 2003	See-through magnets hang tough Researchers from the Independent University of Barcelona (UAB) and the University of Zaragoza in Spain have found a way to form transparent, durable, lightweight magnets that maintain their magnetism in magnetic fields and high temperatures.
Technology Research News July 30, 2003	Munching microbes feed fuel cell Researchers from the Ernst Moritz Arndt University in Germany have found a way to harvest the energy needed to power a fuel cell from chemical reactions that occur when E. coli bacteria consume sugar.
Technology Research News July 30, 2003	Crystal cracks nurture nanowires Researchers from the University of Tokyo in Japan have devised a way to form titanium nanowires within an intentionally flawed sapphire.
PC Magazine July 29, 2003 Alfred Poor	Hand Prints PrintDreams of Kista, Sweden, may make portable printing applications possible with its Random Movement Printing Technology (RMPT). Slide a printing gadget based on this technology over a flat surface and you've got a printout.
