Materials Chemists Apply Photonic Crystals to Forensics
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new ... > more -
Mechanical Engineers' Device Helps Electricity Conservation
Smart meters are small computers that provide real-time information on how much electricity is being used by each customer and when, and can relay information back to the head office over the very ... > more -
Human Factors Research Suggests Ways to Keep Drivers Alert
The human factor -- such as the lag in reaction to unforeseen events -- is the primary cause of road accidents. Researchers are now experimenting with WiFi technology to make cars talk to each ... > more -
Biochemists Develop Diagnostic Tool to ID Strains Faster
Biochemists have developed a new tool that can identify a strain of influenza in hours, instead of the usual days or weeks, potentially speeding up the development of new vaccines. A sample of the ... > more -
MRI Can Replace CT Scans, Reducing Cancer Risks
New studies by radiologists have shown that MRI can be just as accurate as CT scans at helping radiologists diagnose pathologies such as cancer, cysts and kidney stones -- while carrying less risk, ... > more -
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 -
Industrial Toxicologists Develop Cost-Effective, Life-Saving Disinfection
Industrial toxicologists at a non-profit venture founded by Procter & Gamble developed PUR, a water purifier that combines a flocculant -- which separates particles and organisms from water -- ... > 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 -
Food Chemists Find that Milk Pushes Air to Break Crystallized Sugar
Food scientists have discovered why Rice Krispies make their characteristic sound when soaked in milk. Rice Krispies contain lots of sugar and are cooked at high temperature, which makes the sugar ... > 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
