Ecologists Deploy Wireless Sensors for Early Detection of Wildfires
New fire-sensing devices can spot a fire in its earliest stages, up to six miles away, and they can relay the information to emergency responders through a computer network and even automatically ... > more -
Computer Engineers Improve Wireless Networks by Making Users Connect Through Each Other
Several cities, including Philadelphia and San Francisco, are considering installing city-wide wireless internet connections of a new generation. These so-called wireless mesh networks will enable ... > more -
Neurosurgeon Devises MRI-Based Technique to Diagnose Sciatica
Up to 40 million American suffer from sciatica pains, but the condition is often not diagnosed correctly. A new imaging technique uses a specially tuned MRI scan to image nerves and highlight them ... > more -
Mechanical Engineers Have New Bug-Inspired Robot That Senses Its Way With Flexible Antenna
Researchers have developed a flexible, sensor-laden artificial antenna to help a robotic "bug" move and navigate just like the common cockroach. The bug can curry along walls, turn corners, avoid ... > more -
Applied Physicist Invents Training Golf Club with Audio Feedback
A new golf club uses motion-detection sensors and wireless technology to coach players through the use of sound. A golfer can "hear" the speed of the swing in wireless headphones, and adjust swings ... > more -

Energy Scientists Propose Color-Coding Standard for PC Sleep Mode
Different computers use different indicator lights to signal that they are in energy-saving, or "sleep" mode. Users are often unsure if their PC is truly saving energy, rather than just turning its ... > more -
Engineers Develop Non-Acoustical Sensor to Improve Battlefield Communication
A new device will soon help troops communicate on a noisy battlefield. The Tuned Electromagnetic Resonance Collar -- or TERC sensor -- detects changes in the electrical field around the neck produced ... > more -
Physicists' Invention Opens Access to Computers for Persons with Tremors
For $100, people with tremors could finally be able to use a computer mouse. A new mouse adapter filters out the high-frequency, shaky component of the movement, transmitting only the steady ... > more -
Meteorologists Use Weather Knowledge to Predict Path of Toxic Spills
Homeland security officials are tapping researchers' capability to predict the paths of toxic waste spills and hazardous airborne particles. Using computer science and mathematics, along with ... > more -
Engineers Develop Technique for Recognizing Gun Owner's Grip
Researchers have designed, built and tested a handgun that will fire only when its component circuitry and software recognize the grip of an authorized shooter. The technology measures not only the ... > more -
Acousticians Improve Sound Quality of Cochlear Implants
In a new study, 34 normal-hearing and 18 cochlear-implant subjects were tested on three speech-perception tasks known to be notoriously difficult for cochlear-implant users: speech recognition with a ... > more
