Technology Research News October 17, 2005	Data storage technologies Today's magnetic disk drives could be improved by incorporating much larger magnetoresistance or replaced by microelectromechanical systems (MEMS), near-field optics, holographic systems, or even molecules for better data storage solutions.
Scientific American October 17, 2005 Charles Q. Choi	Transistor Flow Control At the heart of modern electronics are transistors, which act like valves to direct the flow of electrons. Now researchers have created the first transistors that electrically control molecules instead.
Scientific American October 17, 2005 Graham P. Collins	Quantum Bug Physicists must overcome a fundamental obstacle before quantum computers can become a practical reality: decoherence, which is the loss of the very quantum properties that such computers would rely on.
PC Magazine October 12, 2005 Sebastian Rupley	Walking for Watts Researchers have created a backpack that converts mechanical energy from walking into power.
CIO October 15, 2005 Diann Daniel	A Computer at Astronauts' Command A voice-operated computer named Clarissa has been developed to help astronauts with their work by reading aloud instructions to procedures.
The Motley Fool October 11, 2005 Dan Bloom	Intel's Optical Breakthrough The chipmaker may open new tech frontiers by teaching silicon and light to cooperate.
Military & Aerospace Electronics October 2005 Gurnett & Adams	Can ISO Standards Smooth the Lead-Free Transition? In the long run, the global legislative demand being made by lead-free rules and the European Reduction of Hazardous Substances rule in the consumer world will benefit military and aerospace users.
Military & Aerospace Electronics October 2005 Ben Ames	Digital receivers power a new generation of electronic warfare Military technology designers have shifted from analog to digital radar receivers to deal with decentralized threats. The change is a major improvement for size, weight, and power.
Military & Aerospace Electronics October 2005 Steffen Koehler	Advances in hybrid optical packaging enable high-bandwidth photonic RF transmission The challenge in exploiting optical fiber for RF transmission lies in getting the RF signals on and off the fiber without degrading the signals. Advances in optical packaging technology are making improvements to military equipment possible.
Military & Aerospace Electronics October 2005	Method of heat removal is critical in design Far too often cooling is an afterthought in the design of the latest "black box" and by the time it is parameters such as power, volume, and weight are all at a premium.
