Science Daily- Eagle Nebula: An Eagle Of Cosmic ProportionsA new and stunning image of the sky around the Eagle Nebula, a stellar nursery where infant star clusters carve out monster columns of dust and gas has been released.
- Arctic Sea Ice Images Derived From Classified Data Should Be Made Public, According To A New ReportHundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report.
- Classifying 'Clicks' In African Languages To Clear Up 100-year-old MysteryA new way to classify sounds in some human languages may solve a problem that has plagued linguists for nearly 100 years -- how to accurately describe click sounds distinct to certain African languages.
- Flu Mortality Formula Is Potentially Misleading, Say ScientistsA standard calculation used in forecasting potential numbers of deaths during the swine flu pandemic risks misleading health-care planners by being open to both over- and under-estimation of the true figures, according to experts.
- Hormone Clue To Root GrowthPlant roots provide the crops we eat with water, nutrients and anchorage. Understanding how roots grow and how hormones control that growth is crucial to improving crop yields, necessary to address food security and produce better biofuels. Scientists have now shed light on how a plant hormone is crucial in controlling the growth of plant roots.
- Radiation Dose, Cancer Risk From Coronary Artery Calcium Screening EstimatedA study based on computer modeling of radiation risk suggests that widespread screening for the buildup of calcium in the arteries using computed tomography scans would lead to an estimated 42 additional radiation-induced cancer cases per 100,000 men and 62 cases per 100,000 women, according to a new report.
- Wood Stoves -- A Viable Home Heat Source?In Canada and the United States, wood burning stoves have been reevaluated as a potentially viable option for home heating. The environmental sustainability of wood stove use is dependent upon the consumption of wood from sustainably managed woodlots, as the carbon released is reused as the next generation of trees grows.
- Who Am I? Adolescents' Replies Depend On OthersAsk middle-school students if they are popular or make friends easily, they likely will depend on social comparisons with their peers for an answer. Such reliance on the perceived opinions of others, or reflected self-appraisals, has long been assumed, but new evidence supporting this claim has now been found in the teen brain.
- Blind Can Take Wheel With Newly Designed VehicleA retrofitted four-wheel dirt buggy uses laser range finders, an instant voice command interface and a host of other innovative, cutting-edge technology to guide blind drivers as they steer, brake and accelerate.
- Asperger Syndrome, Autism, And Empathy: Study Links 27 GenesScientists have identified 27 genes that are associated with a number of traits, including Asperger syndrome, autism, and empathy.
