"FPGAs: Self-configuring array enables atomic-scale fabrication"
A next-generation configurable circuit architecture is being proposed by a group of designers at startup Cell Matrix Corp. The architecture goes beyond basic FPGAs by building arrays of "cells" rather than simply reconfigurable gates. Each cell has a small amount of logic and local memory and communicates with its nearest neighbor. The company is building small prototype chips based on the concept.

"ANTHRAX: detects in 5 minutes"
Curtis Mowry discusses his five-minute handheld biological agent detector--the ultimate goal of a Sandia National Laboratories research project that recently reported having successfully tested all of its subcomponents. A football-sized analysis unit was made possible by microelectromechanical systems (MEMS)-based components, enabling all but one subsystems necessary for the device to be integrated into a single handheld unit.

"REVERSE COMPUTATION: unsnarls net knots"
Christopher Carothers discusses his Rensselaer Polytechnic Institute research on reversible computer simulations--the elixir for unsnarling tough networking problems, such as the illusive 1,000,000 node TCP simulator. He recently won a Faculty Early Career Development (CAREER) Award from the National Science Foundation for Networking Research on reversible computing.

"PLASTIC HDs: Magnetized polymer eyed as storage medium"
The world's first photo-induced magnetism in a polymer was demonstrated by researchers here at Ohio State University and at the University of Utah, Salt Lake City. In the experiment, a blue laser raised the magnetism of the polymer by 50 percent; a green laser brought it back to nominal. The pure-research finding, at 75 K (325�F below zero), could lead to room-temperature storage devices, such as hard disks, that could be written at high densities by laser-based read/write heads, the researchers said.

"PHOTONICS: Material converts IR waves into visible light"
A team from the University of Buffalo has developed an organic material which is capable of absorbing three photons at infrared (IR) wavelengths and re-emitting the light in the visible spectrum. The group, led by Professor Paras Prasad of the university's Institute for Lasers, Photonics and Biophotonics, designed the material specifically with the aim of developing three-photon absorption at 1.3 micrometers, a frequency used for fibre optic communications.
