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 -
Physical Chemists Devise Quick Spectrometry-Based Mercury Test
Physical chemists have created a new, cheap test to detect mercury, an element known to harm the brain, kidneys, heart, lungs and immune system. A gold nanorod absorbs mercury from a sample and, then ... > 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 -
Gastroenterologists Use Hi-Res Narrow-Band Imaging to Find Cancer
Gastroenterologists Use Hi-Res Narrow-Band Imaging To Find Cancer New optical technologies are helping gastroenterologists improve cancer detection using colonoscopy. A new endoscope uses HDTV ... > more -
Rheologists Apply Shear-Thickening Fluids to Protective Gear
Rheologists have created a new way of bullet-proofing clothes using shear-thickening fluids. Fabric treated with shear-thickening granular suspensions can turn soft material into solid protective ... > 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 -

Mimicking Insects to Avoid Sinking Using Surface Tension
A new robot made of ultralight carbon-fiber can stand or slowly walk on water. The principle it uses is borrowed from insects -- surface tension tends to prevent the water's surface from breaking, ... > more -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > more -
Environmental Engineers Link Contamination Levels to Tides
By washing decomposing plants into the ocean, high tides could contribute to the increased levels of Enterococci that are often responsible for beach closures. Scientists have now established a clear ... > more
