"One of the things we'll be doing as we move forward with this work is seek ways to limit that mechanical work change," Huang says.

"Any system that involves a human interface will have occasional errors," Huang notes. "But we think we can find ways to make those errors effectively insignificant."

NRL scientists discover novel metamaterial properties within hexagonal boron nitride

WASHINGTON - U.S. Naval Research Laboratory (NRL) scientists, in collaboration with researchers from the University of Manchester, U.K.; Imperial College, London; University of California San Diego; and the National Institute of Material Science (NIMS), Japan, have demonstrated that confined surface phonon polaritons within hexagonal boron nitride (hBN) exhibit unique metamaterial properties that enable novel nanoscale optical devices for use in optical communications, super-resolution imaging and improved infrared cameras and detectors.

Oat oil preparation makes you feel fuller

Oat oil preparation makes you feel fuller

Oats contain more fat than other cereals, and oat oil has a unique composition. A new study from Lund University, Härröd Research and Swedish Oat Fiber AB, shows a special oat oil preparation can produce greater satiety.

A path to brighter images and more efficient LCD displays

A path to brighter images and more efficient LCD displays

SALT LAKE CITY, Nov. 20, 2014 - University of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light.

Polarizers are indispensable in digital photography and LCD displays, but they block enormous amounts of light, wasting energy and making it more difficult to photograph in low light.

Theater arts research offers insight for designers, builders of robots

As an actress, producer, director and theatre arts lecturer at The University of Texas at Arlington, Julienne Greer knows the techniques that help draw people's deepest emotions to the surface. Now, she's building on her experience and research to help scientists and robotics engineers better understand the human experience so that they can build more responsive robots.

Education empowers Canadians but raises risks of overwork and work-family stress

The higher your level of education, the greater your earnings and your sense of "personal mastery" or being in control of your fate, University of Toronto researchers say. But wait: there's a downside.

Hand dryers can spread bacteria in public toilets, research finds

Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new University of Leeds research.

Scientists from the University of Leeds have found that high-powered 'jet-air' and warm air hand dryers can spread bacteria in public toilets. Airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.

The study shows that both jet and warm air hand dryers spread bacteria into the air and onto users and those nearby.
