Military & Aerospace Electronics March 2005 Sansone & Emslie	Fiber sensing receives renewed interest History will remember optical-fiber technology as one of the truly great inventions of the 20th century: it is the driver behind the telecommunications revolution and the very backbone of the Internet, telephony, and Cable TV
Military & Aerospace Electronics March 2005 Tom Adams	The shrinking-package approach to low-cost, robust sensor arrays One potential benefit of shrinking the sizes of microelectronics components is the potential to scatter a large number of sensors arranged as a distributed array over an area for surveillance.
Military & Aerospace Electronics March 2005 Ben Ames	Sandia researchers set sights on battlefield robots Now researchers at Sandia National Laboratories in Albuquerque, N.M., are building systems that combine the strengths of humans and robots.
InternetNews March 15, 2005 Michael Singer	HP Plots Its Nano Course Company believes in moving computing beyond silicon to the world of molecular-scale electronics.
Technology Research News March 9, 2005 Eric Smalley	Wire Guides Terahertz Waves Among the challenges to making terahertz sensing and imaging applications more practical is finding ways to direct the waves to specific targets. Researchers have now shown that a piece of stainless steel wire 9/10ths of a millimeter in diameter causes terahertz waves to propagate in the space around wire.
Technology Research News March 9, 2005	Pattern Recognition: Computers and Human Communications A computer's ability to track and interpret the types of input humans use to communicate - gestures, words and facial expressions - is not enough. Meaning is often conveyed by a combination of different types of sensory input. Words and gestures, for example, can go together to produce meaning that cannot be determined from simply examining the inputs separately.
Technology Research News March 9, 2005	Quantum Crypto Scheme Goes One-Way Quantum cryptography researchers from Toshiba Research have demonstrated a one-way quantum key distribution system that automatically compensates for phase drift.
Technology Research News March 9, 2005	Method Makes Double Nanotubes Researchers can now fabricate pure batches of double-walled carbon nanotubes, which theoretically should be more thermally and chemically stable than single walled nanotubes.
Technology Research News March 9, 2005	Material Promises Denser DVDs Researchers have found a way to use electron beams to read, write and erase bits. The technology could lead to high-speed, ultrahigh density storage media; the material at the heart of the technology could also be used in solar cells.
Technology Research News March 9, 2005	Artificial Cochlea Tells Tones Apart The artificial cochlea makes it easier to study the precise mechanics of the ear. It also paves the way for economical microphones that work as well as ears, and could eventually be used as cochlear prostheses.
