Technology Research News December 17, 2003 Patch & Smalley	Body handles nanofiber better The human body doesn't care for artificial materials, and responds to invasions by building scar tissue around foreign objects. A study shows that scar tissue formation might have more to do with the surface features of the intrusion than material it is made from.
Technology Research News December 17, 2003 Eric Smalley	Microfluidics make flat screens A new method for making big, cheap flat screen displays is a bit like making muffins. Pour liquid polymer into microfluidic channels aligned above an array of electrodes, let cure, and you have organic thin film transistors.
Technology Research News December 17, 2003	Chemists grow nano menagerie Researchers from Sandia National Laboratories have found a simple way to make tiny, complicated shapes from zinc oxide, including arrays of vertically-aligned rods, flat disks, and columns that resemble stacks of coins.
Technology Research News December 17, 2003	Solid fuel cell works in heat California Institute of Technology researchers have built a type of fuel cell that uses a solid acid electrolyte and either hydrogen or methanol as fuel. It could eventually be used to power cars.
Technology Research News December 17, 2003	Hybrid crypto secures images Researchers from National Chung Cheng University and National Yunlin University of Science and Technology in Taiwan have devised a way to encrypt in a single communication an image and the secret session key that unlocks the image.
Technology Research News December 17, 2003	Chip uses oil to move droplets Researchers from North Carolina State University have devised a way to manipulate tiny droplets and particles on a chip. Key to the system is suspending what needs to be moved in a heavier liquid.
Technology Research News December 17, 2003	Light spots sort particles Researchers from the University of St. Andrews in Scotland have found a cheap, simple way to sort microscopic particles by size and by refractive index. A material's refractive index has to do with how much it bends light. This technology will likely speed efforts to make labs-on-chips.
Technology Research News December 17, 2003	Organic transistors get small Researchers from Cornell University have shown that it is possible to fabricate useful organic thin film transistors that have a channel length as small as 30 nanometers. The smaller the channel, the faster the transistor. Previously, organic TFT channel lengths were limited to about 100 nm.
Bio-IT World December 15, 2003 Michael Greeley	Tiny Devices, Big Opportunities Parallel advances in drug formulation and microprocessing and other manufacturing technologies are creating new products and services as these industries start to intersect.
Reactive Reports December 2003 David Bradley	Airy magnets Spanish researchers have created a new type of magnetic material that is ultra-light and transparent. The airy magnets could have applications in flat screen displays and magneto-optical memory devices for computers.
