Bacteria Research Offers Hope For New Vaccine Against Meningococci
Blood poisoning and meningitis are acute life-threatening infections that are often caused by meningococcus bacteria. The course of the disease is still relatively unknown, but a research team at Uppsala University led by Professor Ann-Beth Jonsson has managed to monitor the movements of the bacteria and glean information that may help in the development of new vaccines against the diseases. The study is being published in the new issue of the online journal PLoS ONE.

Tone Deafness Explained
Do people cringe when you sing? You've got company. But researchers have found that only 1 in 20 people truly has amusia, the technical term for tone deafness. Tests have shown that some people with bad singing voices hear music just fine. Amusics are a smaller group with a perceptual problem: They can't pick out differences in pitch or follow the simplest tunes.

Acid Oceans From Carbon Dioxide Will Endanger One Third Of Marine Life
The world's oceans are becoming more acid, with potentially devastating consequences for corals and the marine organisms that build reefs and provide much of the Earth's breathable oxygen. The acidity is caused by the gradual buildup of carbon dioxide in the atmosphere, dissolving into the oceans. Scientists fear it could be lethal for animals with chalky skeletons which make up more than a third of the planet's marine life.

Pilot Plant On Stream To Turn Manure Into Usable Energy
The Alberta Research Council (ARC) and Highmark Renewables have marked the official opening of a new pilot plant at Highland Feeders, one of Canada's largest feedlot operations. The plant demonstrates new technology developed jointly by ARC and Highmark Renewables to transform manure into energy, bio-based fertilizers and reusable water, while reducing greenhouse gas emissions and other environmental impacts associated with land application of manure.

Robotic Arm Holds Promise For Stroke Survivors
Arizona State University researchers and Tempe-based Kinetic Muscles, Inc., have developed a robotic arm to help stroke survivors regain the ability to perform basic tasks, such as reaching for objects or feeding themselves. The rehabilitative device aids in task-oriented repetitive therapy, and the hope is that it will provide a cost-effective alternative to traditional therapy. This would enable a wider population to regain maximum motor function.

Scientists Discover Possible Titan Volcano
A recent flyby of Saturn's hazy moon Titan by the Cassini spacecraft has revealed evidence of a possible volcano, which could be a source of methane in Titan's atmosphere. Images taken in infrared light show a circular feature roughly 30 kilometers (19 miles) in diameter that does not resemble any features seen on Saturn's other icy moons. Scientists interpret the feature as an "ice volcano,"a dome formed by upwelling icy plumes that release methane into Titan's atmosphere.

Science-based Teaching Tools On Underage Alcohol Use Under Development
Efforts to halt underage drinking often focus on peer pressure and the prevention of risky behaviors, but the American Association for the Advancement of Science is undertaking a new federally funded project to give middle-school children a science-based understanding of what can happen to them if they use alcohol.

Pollution From Marine Vessels Linked To Heart And Lung Disease
Pollution from marine shipping causes approximately 60,000 premature cardiopulmonary and lung cancer deaths around the world each year, according to a new report. The report benchmarks for the first time the number of annual deaths caused globally by pollution from marine vessels, with coastal regions in Asia and Europe the most affected.
