The quick and easy way to measure power consumption

A novel sensor enables them to do just that, and thereby comply with the new government regulations. The new metering device will be presented at the Sensor+Test 2012 trade fair in Nuremberg from 22 to 24 May.

New 'metamaterial' practical for optical advances

WEST LAFAYETTE, Ind. - Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar cells.

The researchers have shown how to create the metamaterials without the traditional silver or gold previously required, said Alexandra Boltasseva, a Purdue University assistant professor of electrical and computer engineering.

The use of acoustic inversion to estimate the bubble size distribution in pipelines

New research from the University of Southampton has devised a new method to more accurately measure gas bubbles in pipelines.

Getting in tune: Researchers solve tuning problem for wireless power transfer systems

Researchers from North Carolina State University have developed a new way to fine-tune wireless power transfer (WPT) receivers, making the systems more efficient and functional. WPT systems hold promise for charging electric vehicles, electronic devices and other technologies.

Researchers have shown that it is possible to transmit power wirelessly by using magnetic resonance. Even minor changes in how the transmitter or receiver is tuned, however, can result in faulty power transmission.

Secret soil cracks linger, despite surface sealing

Sydney, Australia - Deep cracks in soil can remain open underground even after they have visibly sealed on the surface, a new study has found.

The results could have important implications for agricultural management around the timing and intensity of water and pesticide applications.

"These soils are very fertile and provide the most productive agricultural land in Australia," said lead author Dr Anna-Katrin Greve, a postdoctoral fellow with UNSW's Connected Waters Initiative.

Beyond the high-speed hard drive: Topological insulators open a path to room-temperature spintronics

Strange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. First theorized and then discovered by researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues in other institutions, these "strong 3-D topological insulators" – TIs for short – are seemingly mundane semiconductors with startling properties. For starters, picture a good insulator on the inside that's a good conductor on its surface – something like a copper-coated bowling ball.

Microbe that can handle ionic liquids

In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing.

Study finds number of battery-related emergency department visits by children more than doubles

"We live in a world designed by adults for the convenience of adults, and the safety of children is often not considered," said Gary Smith, MD, DrPH, director of the Center for Injury Research and Policy at Nationwide Children's Hospital. "Products with easily-accessible battery compartments are everywhere in our homes today.

Dip chip technology tests toxicity on the go

From man-made toxic chemicals such as industrial by-products to poisons that occur naturally, a water or food supply can be easily contaminated. And for every level of toxic material ingested, there is some level of bodily response, ranging from minor illness to painful certain death.

You can't play nano-billiards on a bumpy table

There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the "billiard balls" are tiny electrons moving across a "table" made of the semiconductor gallium arsenide.

Floating robots use GPS-enabled smartphones to track water flow

Berkeley—A fleet of 100 floating robots took a trip down the Sacramento River today (Wednesday, May 9) in a field test organized by engineers at the University of California, Berkeley. The smartphone-equipped floating robots demonstrated the next generation of water monitoring technology, promising to transform the way government agencies monitor one of the state's most precious resources.

Simulation training improves critical decision-making skills of ER residents

DETROIT – A Henry Ford Hospital study found that simulation training improved the critical decision-making skills of medical residents performing actual resuscitations in the Emergency Department.

Researchers say the residents performed better in four key skill areas after receiving the simulation training: leadership, problem solving, situational awareness and communication. Their overall performance also sharpened.

Navigating the shopping center

A smartphone with GPS functionality is a delightful tool. It guides its owner safely and with certainty through the streets of an unfamiliar city. But after arriving at the destination, all too often the orientation is gone, because as soon as you enter a building, you lose contact with the GPS satellites. Then you are on your own – whether in the interminable hallways of the trade fair complex, or inside one of the branches of the local megaplex shopping mall.

A push from the Mississippi kept Deepwater Horizon oil slick off shore, Penn research shows

PHILADELPHIA — When the Deepwater Horizon drilling rig exploded April 20, 2010, residents feared that their Gulf of Mexico shores would be inundated with oil. And while many wetland habitats and wildlife were oiled during the three-month leak, the environmental damage to coastal Louisiana was less than many expected, in part because much of the crude never made it to the coast.
