Technology Research News November 3, 2004	Lasers Move Droplets Labs-on-a-chip promise inexpensive and portable biological and chemical analysis. The key to making the tiny labs work is finding ways to move and mix minuscule amounts of substances.
Technology Research News November 3, 2004	Molecules Form Nano Containers Researchers have found a way to coax the self-assembly of minuscule multicompartment structures. The structures could eventually be used in drug delivery systems.
Technology Research News November 3, 2004	Square Rings Promise Reliable MRAM Researchers are working on magnetic random access memory chips that hold as much data as standard electronic memory chips. The key to a promising design is a nanowire bent into a circle.
Wired November 2004 Michael Erard	The Geek Guide to Kosher Machines For decades, observant Jews have found ways to work around Sabbath restrictions in the kitchen, but high-tech appliances cause problems. Jonah Ottensoser works with manufacturers to give appliances a kosher seal of approval.
CFO November 1, 2004 John Edwards	Let There Be Cheaper Light In the long run, LED devices can generate big savings in energy consumption.
Technology Research News October 20, 2004 Eric Smalley	Biochip spots single viruses A detector recently built from nanowire transistors can identify individual virus particles in real time in unpurified samples. Labs-on-a-chip based on the device could be used to monitor diseases.
Technology Research News October 20, 2004 Kimberly Patch	Cooler material boosts fuel cells A cathode that allows solid oxide fuel cells to operate at reduced temperaures promises to lower the cost of fuel cells, which could spur broader adoption of the technology.
Technology Research News October 20, 2004 Eric Smalley	Wide laser makes simple tweezers Much of medical diagnostics and biomedical research involves trapping, manipulating and sorting individual cells and like-sized bits of matter. A recently demonstrated way of manipulating cells promises to be less expensive than laser tweezers.
Technology Research News October 20, 2004	Biochip levitates droplets Researchers have devised a way to magnetically levitate particles and droplets that have volumes smaller than one billionth of a milliliter. Labs-on-a-chip is one of many potential uses.
Technology Research News October 20, 2004	Nanotubes form transparent film A maximum amount of contact between nanotubes within the film makes it a good electrical conductor. The film could eventually be used to make foldable computer displays, infrared cameras and line-of-sight optical communication devices.
