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 -
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 -
Automotive Engineers Team Up to Improve Energy-Saving Technology
Mechanical and electrical engineers at DaimlerChrysler, General Motors and BMW have jointly developed a hybrid-vehicle technology that shuts the internal combustion engine off when the vehicle stops. ... > 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 -
Human-Factors Engineers Focus on User-Friendliness
Human-factors engineers -- whose training includes psychology -- specialize in testing products for usability, for example checking whether a copying machine's legs get in the way, or measuring how ... > more -
Engineers Test Ventilated Seats And Thermal-Acoustic System To Make A/C Energy-Efficient
Engineers at a national lab have shown that small fans embedded in car seats could help cool passengers down -- saving up to 7 percent of the 30 to 40 gallons of gasoline per year an average driver ... > more -
Physical Chemists Develop New High-Capacity Storage Technology
Holograms allow permanent optical data storage and retrieval with far higher densities than CDs or DVDs, using the interference patterns of two lasers. Physical chemists are now developing the ... > more -
Civil Engineers Learn from Dutch Flood Barrier System
A group of U.S. civil engineers and city officials went on a recent trip to the Netherlands -- a country much of which is below sea level -- to study the country's storm surge barrier system. The ... > more -
Oceanographers Uncover The Physics Of Rip Currents
Rip currents flow in very erratic patterns, not in steady courses as previously believed -- which may help explain why they can be so dangerous even for experienced swimmers. Oceanographers have ... > more
