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 -
Biomedical Engineers' 'Body-on-a-Chip' Could Reduce Cost of Developing New Drugs
A new kind of microchip can host human cells to mimic the reaction of different tissues in the body. The chip could help reduce the need for animal testing, and lower the cost of developing new ... > 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 -

Simulating Impaired Reflexes Teaches Effects of Drunk Driving
Health educators can now give students a realistic taste of the perils of drunk driving, using a DUI simulator. Special go-carts delay the reaction of the brake and gas pedals and exaggerate the ... > more -
Mechanical and Aerospace Engineers Show Human Locomotion Optimizes Energy Use
Computer models of human locomotion are helping engineers understand why walk and run instead of hopping and skipping. The models are revealing that walking and running are the most energy-saving ... > more -
Entomologists Train Insects to Act Like Sniffing Dogs
If rewarded with sugary water, wasps can be trained in minutes to follow specific smells. The olfactory sensors in their antennae can sense chemicals in the air in concentrations as tiny as a few ... > more -
Young Inventors' Firefighting Robots Are More than Just Fun Toys
At an international high-school contest based in Connecticut, students compete with their home-made robots. The goal for the robots is to navigate a maze, find a fire, and put it out in the shortest ... > more -
Engineers Create Exhibits on Achievements, Promise
Nanotechnology has already brought advances such as self-cleaning windows and energy-efficient LED lighting, and could soon deliver medical breakthroughs. To educate the public about nanotechnology's ... > more
