The Dying Swan is sometimes moving smoothly and gently, sometimes in a dramatic and fiery manner, as Tchaikovsky´s majestic music from the ballet Swan Lake is playing. Yet this is no ordinary ballet dancer, but a robot in the form of a swan, created at Mälardalen University and choreographed by professional dancer Åsa Unander-Scharin.

Electric cars hold greater promise for reducing emissions and lowering U.S. oil imports than a national renewable portfolio standard, according to research conducted by Rice University's Baker Institute for Public Policy.

INDIANAPOLIS – Not since victory gardens helped World War II era Americans on the home front survive food shortages have urban gardens been as necessary and popular as they are today. With more food production in cities, the safety of the produce grown there becomes increasingly important.

Elevated concentrations of nitrogen and phosphorus, nutrients that can negatively impact aquatic ecosystems and human health, have remained the same or increased in many streams and aquifers across the Nation since the early 1990's, according to a new national study by the U.S. Geological Survey.

A team led by engineers and physicists at the University of New South Wales (UNSW) in Sydney, Australia, have developed one of the key building blocks needed to make a quantum computer using silicon: a "single electron reader". Their work was published today in Nature.

Quantum computers promise exponential increases in processing speed over today's computers through their use of the "spin", or magnetic orientation, of individual electrons to represent data in their calculations.

STANFORD, Calif. - People go to emergency departments when they've broken a leg, been stabbed or otherwise need urgent care. But a new study from the Stanford University School of Medicine finds that 90 percent of EDs nationwide also offer preventive-care services.

The high prevalence was surprising, said M. Kit Delgado, MD, the study's lead author and a postdoctoral scholar at Stanford's Center for Primary Care and Outcomes Research, and it likely stems from less-than-ideal conditions.

STANFORD, Calif. - Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins.

With several advanced warfare vehicles and a lineup of exciting technologies, the Office of Naval Research (ONR) will showcase its latest expeditionary equipment at the 2010 Modern Day Marine Exposition scheduled Sept. 28-30 at Quantico Marine Corps Base, Quantico, Va.

Sept. 24, 2010 — Biometric systems -- designed to automatically recognize individuals based on biological and behavioral traits such as fingerprints, palm prints, or voice or face recognition -- are "inherently fallible," says a new report by the National Research Council, and no single trait has been identified that is stable and distinctive across all groups. To strengthen the science and improve system effectiveness, additional research is needed at virtually all levels of design and operation.

A team led by a North Carolina State University researcher has shown that water-gel-based solar devices – "artificial leaves" – can act like solar cells to produce electricity. The findings prove the concept for making solar cells that more closely mimic nature. They also have the potential to be less expensive and more environmentally friendly than the current standard-bearer: silicon-based solar cells.

The well-documented disparities in cardiac care may begin almost as soon as patients arrive at hospital emergency rooms. In a study published in Academic Emergency Medicine, Massachusetts General Hospital (MGH) researchers report that African-American and Hispanic patients assessed for chest pain were less likely than white patients to be categorized as requiring immediate care, despite a lack of significant differences in symptoms.

As the shipping industry's emissions are predicted to continue to grow in the future, the UK will fail to meet its commitment to avoid dangerous climate change if additional cuts are not made to other sectors.

According to a University of Manchester study, the global shipping industry, despite being traditionally viewed as one of the most energy efficient means of transport, releases increasing amounts of harmful emissions into the atmosphere every year.

In a series of reports to be presented at a major conference this week, scientists at The University of Manchester claim using sustainable wood and other biofuels could hold the key to lowering harmful greenhouse gases.

Building district heating schemes which would provide heat and hot water for a neighbourhood or community would not only drastically reduce greenhouse gases but would also be highly cost effective, the authors claim.

One touch directs a robotic arm to grab objects in a new computer program designed to give people in wheelchairs more independence.

University of Central Florida researchers thought the ease of the using the program's automatic mode would be a huge hit. But they were wrong – many participants in a pilot study didn't like it because it was "too easy."
