Micro-X-Ray Fluorescence Also Provides Spectroscopic Information
Ordinary invasive fingerprinting techniques, such as dusting, are prone to damaging evidence. Micro-X-ray fluorescence images fingerprints without touching them. By stimulating atoms to emit ... > more -
Sniffing Dog Provides Cost-Effective Contamination Detection
America's only dog that's trained to sniff mercury is able to detect as little as a half-gram, and is faster and cheaper than traditional lab analysis. Dogs' olfactory membranes are larger and 44 ... > more -
3D Imaging System Helps Athletes Recover from Injuries
A new computer-based system gives physical therapists real-time, objective measures of the motion of each joint in the patient's body. The system uses magnetic trackers to read the positions of ... > more -
Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more -
EMG Helps Physiatrists Find Causes of Pain
Electromyography (EMG) detects the electrical potential generated by muscle cells, and can test nerve function. EMG can help physiatrists pin down the cause of back pain in cases such as spinal ... > more -
Pressure Sensors and Transducers Help Make Dummies More Life-Like
Electrical, computer, and biological engineering combine in creating baby-patient simulators for training new pediatricians. A new simulator incorporates microelectromechanical systems (MEMs) and ... > more -
Portable Machines Go Beyond Prenatal Uses
Ultrasound uses sound waves that bounce off body parts, producing echoes. A computer translates the echoes into images that rival the quality of CAT scans and MRIs, showing broken bones, muscle ... > more -
Pavement Markings Make Drivers Feel They Are Going Too Fast
Engineers have developed new pavement markings that give drivers the illusion that the car is moving faster than it really is. The markings, called optical speed bars, are series of lines painted at ... > more -

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
