Technology Research News December 1, 2004 Kimberly Patch	Conversational Engagement Tracked Researchers are aiming to allow computers to automatically assess peoples' engagement in a conversation by analyzing the way they speak rather than what they say.
Technology Research News December 1, 2004 Eric Smalley	Pure Silicon Laser Debuts Researchers have made a prototype laser from silicon. The laser is tunable, meaning it can lase in a range of wavelengths, or colors, and it works at room temperature.
Technology Research News December 1, 2004	Tight Twist Toughens Nanotube Fiber Researchers have strengthened carbon nanotube yarn by introducing a tight twist as the nanotubes are spun.
Technology Research News December 1, 2004	Multicamera Surveillance Automated Researchers have developed a multi-camera surveillance system that allows the user to indicate an object in one view and automatically zoom to that object in all other views.
Technology Research News December 1, 2004	Smart Dust Gets Magnetic One of the main challenges in making labs-on-a-chip is finding ways to control and mix tiny amounts of liquids. Researchers are using minuscule silicon particles to carry out these tasks.
Technology Research News December 1, 2004	Short Nanotubes Carry Big Currents Researchers have developed a simple way to fabricate carbon nanotube devices whose length is as small as ten nanometers, and have shown that electricity can pass through the nanotubes very efficiently.
Technology Research News December 1, 2004	Demo Advances Quantum Networking Researchers have transferred information stored in the properties of a cloud of rubidium atoms to the properties of a single photon. The ability to transfer information from atoms to photons is needed for quantum computers.
Home Toys December 2004 Jan Plummer	Loudspeakers and the Digital Age The requirements for the loudspeaker in the digital age must meet the standards imposed on the rest of the chain. The first is for the speaker to provide accurate sound information under the same conditions as the electronics may be used.
Home Toys December 2004	Am I Getting Old? - Have my Kids Made me Senile? Using basic technology -- no cord, no batteries, no Global Positioning System (GPS) -- high impact plastic, a metal ring and a few pictures, these scientists have developed the C-Car car-finding keychain. It's embarrassingly simple.
Industrial Physicist Jennifer Ouellette	Quantum Key Distribution Several companies have focused on bringing one aspect of quantum communications to market, quantum key distribution, used to exchange secret keys that protect data during transmission.
