Technology Research News October 8, 2003 Eric Smalley	E-paper closes in on video Watching full motion video on a display that you can roll up and stuff in your pocket is a tantalizing prospect. An electronic ink that changes about 70 times a second brings this vision closer to reality. The technology is all about combining oil and water.
Technology Research News October 8, 2003 Eric Smalley	Magnetic memory makes logic Magnetic memory will soon put an end to the daily annoyance of waiting while your computer boots up from its hard disk. These chips that hold data when the power is off might also be capable of a lot more. Adding a few extra wires to each memory cell could turn the chips into efficient computer processors.
Technology Research News October 8, 2003 Kimberly Patch	Old idea retooled for security Computers have become quite powerful over the years, but they remain less than reliable. A concept widely used in mainframe computing in the '70s and '80s -- the virtual machine -- could keep computers safe and sound in the age of hackers and viruses.
Technology Research News October 8, 2003 Kimberly Patch	Crystal slows and speeds light Playing tricks with light -- speeding, slowing and storing it -- is becoming a popular pastime among physicists. The effects could eventually be used to improve communications and data storage and help bring about quantum computing and quantum communications.
Technology Research News October 8, 2003	Process orders nanowire arrays Harvard University researchers have found a way to neatly layer and pattern rows of nanowires.
Technology Research News October 8, 2003	CD writer generates holograms Researchers from Cambridge University in England have found a way to turn an ordinary CD writer into a device that burns two-dimensional holograms onto CDs.
Technology Research News October 8, 2003	Nanotubes boost storage Scientists from IBM Research in Zurich, Osaka Prefecture University in Japan, and the Japanese Nanotechnology Research Institute have advanced the possibilities of using multiwalled carbon nanotubes to make denser, more efficient data storage devices.
Technology Research News October 8, 2003	Nanotubes harvest electrons Researchers from the University of Bologna and the University of Trieste in Italy, and the University of Notre Dame have found a way to alter carbon nanotubes so that they efficiently separate electrical charge. The method could lead to more efficient solar cells.
Technology Research News October 8, 2003	Bacteria make more electricity Researchers from the University of Massachusetts at Amherst have identified a microorganism that is particularly good at converting sugars to electricity under natural conditions.
Technology Research News October 8, 2003	Design enables large neural nets Researchers have devised a neural network architecture that uses a different mix of optics and electronics than previous schemes in order to accommodate large numbers of neurons.
