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."
The fifteenth tropical depression of the Atlantic Ocean season has formed in the south-central Caribbean Sea, and the GOES-13 satellite captured its swirling mass of clouds and showers in a visible image today. Watches and warnings are already up for Central America.
Tropical Depression Lisa has had a struggle, and it appears that she's in for more of the same.
Researchers at Mount Sinai School of Medicine have found that the costs of care for patients with cancer who disenrolled from hospice were nearly five times higher than for patients who remained with hospice. Patients who disenroll from hospice are far more likely to use emergency department care and be hospitalized. The results are published in the October 1 issue of the Journal of Clinical Oncology.
