(WASHINGTON) -- Researchers in the Materials Science and Technology division of the Naval Research Laboratory have recently demonstrated electrical injection, detection and precession of spin accumulation in silicon, the cornerstone material of modern device technology, at temperatures up to 225 degrees Celsius. These results provide the first demonstration that spin accumulation in Si is viable as a basis for practical devices which meet the operating temperatures specified for commercial (85˚C), industrial (100˚C) and military (125˚C) applications.

A new biosensor which uses antibody-based technology has been shown to detect marine pollutants such as oil cheaper and faster than current technology. Tests of the new biosensor, published in Environmental Toxicology and Chemistry, reveal how it could be used for the early detection and tracking of oil spills.

The biosensor has been developed by researchers at the Virginia Institute of Marine Science (VIMS) and was tested in the Elizabeth River and Yorktown Creek which both drain into Virginia's Chesapeake Bay.

An examination of the birth records of the more than 7million children born in the state of California during the 1990s and early 2000s has found a clear link between the month in which a child is conceived and the risk of that child later receiving a diagnosis of autism.

Tests of a new antibody-based "biosensor" developed by researchers at the Virginia Institute of Marine Science show that it can detect marine pollutants like oil much faster and more cheaply than current technologies. The device is small and sturdy enough to be used from a boat.

While ultrasound is usually viewed as more cost effective, MRI is most often used to evaluate the rotator cuff. When performing a cost utility analysis, utilizing an ultrasound as the initial imaging test for rotator cuff tear, along with pre-operative MRI to identify alternative and concurrent diagnoses, can be a very effective hybrid imaging strategy, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting.

The U.S. Geological Survey assessment on the economic recoverability of undiscovered, conventional oil and gas resources within the National Petroleum Reserve in Alaska (NPRA) and adjacent state waters is now available.

(SALT LAKE CITY)— New findings from University of Utah School of Medicine researchers show that the retrovirus called XMRV is not present in the blood of patients who have chronic fatigue syndrome (CFS). These findings contradict a widely reported 2009 Science study that linked CFS to XMRV.

WASHINGTON – The Chesapeake Bay Program is a cooperative partnership between the U.S. Environmental Protection Agency and jurisdictions in the bay watershed to oversee the restoration of the bay, with a major focus on controlling the extent of pollutants -- such as nitrogen, phosphorus, and sediment -- entering it.

KINGSTON, ONTARIO – The world's first interactive paper computer is set to revolutionize the world of interactive computing.

"This is the future. Everything is going to look and feel like this within five years," says creator Roel Vertegaal, the director of Queen's University Human Media Lab,. "This computer looks, feels and operates like a small sheet of interactive paper. You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen."

At a time when cosmetics, shampoos, skin creams, and other personal care products already are going green — with manufacturers switching to plant-derived extracts and other natural ingredients — government regulators in Canada are adding to the woes of the silicone-based ingredients long used in these products. That's the topic of an article in the current edition of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.

Evolution is providing the inspiration for University of Adelaide computer science research to find the best placement of turbines to increase wind farm productivity.

Senior Lecturer Dr Frank Neumann, from the School of Computer Science, is using a "selection of the fittest" step-by-step approach called "evolutionary algorithms" to optimise wind turbine placement. This takes into account wake effects, the minimum amount of land needed, wind factors and the complex aerodynamics of wind turbines.

WEST LAFAYETTE, Ind. – Researchers have developed an aluminum alloy that could be used in a new type of mobile technology to convert non-potable water into drinking water while also extracting hydrogen to generate electricity.

Such a technology might be used to provide power and drinking water to villages and also for military operations, said Jerry Woodall, a Purdue University distinguished professor of electrical and computer engineering.

CAMBRIDGE, Mass. -- MIT researchers and their collaborators have come up with an unusual, high performance and possibly less expensive way of turning the sun's heat into electricity.

Boston, MA – A common component in webcams may help drug makers and prescribers address a common side-effect of drugs called cardiotoxicity, an unhealthy change in the way the heart beats. Researchers at Brigham and Women's Hospital (BWH) have used the basic webcam technology to create a tool to look at the effects of medications in real time on heart cells, called cardiomyocytes. These findings were published in the journal, Lab on a Chip on April 11, 2011.

Noise is annoying. It interrupts communication, reduces productivity and tires people out – in extreme cases it can even make them ill. Sound absorbing surfaces are therefore needed in rooms where people work, talk to each other or are trying to relax. These decrease reverberation and so make rooms quieter. However so called acoustically «hard» materials such as glass and concrete, which are commonly used in interior design, scarcely absorb sound at all. Heavy curtains made of material such as velvet are often used to absorb sound.
