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 Establish Accuracy and Usability Standards
Human-factors engineers, along with the National Institute of Standards and Technology (NIST) have developed a rigorous, standardized test for all electronic voting machines -- whose error rate is ... > more -
Robotic Camera Will Take Motion X-Rays by Following Patients' Movements
Orthopedic injuries are among the most common reasons people visit the doctor. Whether it's pain in the knee, hip or shoulder, doctors have a difficult time making an exact diagnosis without surgery. ... > 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 -
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 -
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 -
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
