'High efficiency' vacuum cleaners no better at protecting against dust mites
Researchers at the North West Lung Centre, run by The University of Manchester and based at Wythenshawe Hospital, have discovered that vacuum cleaners with 'high-efficiency particulate air' or HEPA filters are no more effective than standard models at reducing exposure to dust-mites. view more (2006-02-14)
Researchers show how air pollution can cause heart disease
New York University School of Medicine researchers provide some of the most compelling evidence yet that long-term exposure to air pollution-even at levels within federal standards-causes heart disease. view more (2005-12-21)
UCI scientists find chlorine may contribute to ozone formation
Standard methods of predicting air pollution don't take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone production in local air, research at UC Irvine has found. view more (2006-06-14)
Too little scope for development in today's aircraft technology
New technology can do much to improve certain aspects of aviation in terms of sustainable development over the next fifty years, but this will be nowhere near enough to compensate for the expected growth in air travel. view more (2007-06-27)
Diesel exhaust associated with higher heart attack, stroke risk in men
Increased roadway pollution produced by diesel fuel in vehicles is leading to a cascade of conditions that could result in heart attack or stroke. view more (2007-11-06)
Measuring electrical arcs at the micrometer scale
Air is a great insulator-except when it becomes a conductor. Under the right conditions, miniature lightning bolts of electricity will "arc" through the air between two electrically conducting points. view more (2006-03-31)
Fresh-cut produce washing practices can minimize food-borne illness risks
Researchers at the United States Department of Agriculture (USDA) recently examined the safety and quality of "wash techniques" used in the production of packaged produce. view more (2007-12-07)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
Homeopathy no better than placebo for improving quality of life in childhood asthma
Homeopathic remedies, which are often used to improve the quality of life of asthmatic children, are no better than placebo, finds a study in Thorax. view more (2003-03-28)
Clean fuels could reduce deaths from ship smokestacks by 40,000 annually
Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 - almost one-third higher than previously believed, according to the second major study on that topic. view more (2009-07-09)
New "biosensor" screens Air Force personnel and equipment for contamination - within minutes
Air Force personnel will soon know within minutes if they or their equipment are contaminated with a biological agent, thanks to a new technology developed by the Air Force and a national laboratory. view more (2005-06-17)
Peace paradox and air terror
Peace agreements, stability and regional prosperity, in an interesting paradox, increase the risk of air terror in Israel, according to new research conducted by Lieutenant Colonel Ron Tuegeman under the supervision of Prof. Arnon Sofer of the University of Haifa. view more (2008-03-27)

Water method for unsedated colonoscopy; interval between prep and colonoscopy predicts prep quality
In recognition of National Colorectal Cancer Awareness Month during March, GIE: Gastrointestinal Endoscopy has put out a special issue on colonoscopy for colorectal neoplasia. Studies of note regarding colonoscopy appear in both the monthly March issue and the special issue. view more (2009-03-02)
Endotoxins in cigarette smoke
A room where people smoke contains dozens or hundreds of times higher air concentrations of endotoxins than smoke-free indoor air. This has been shown by a research team from Lund University. Endotoxin is the name of a group of poisonous substances produced by bacteria and naturally occurring in the air and elsewhere. In normal low concentrations,... view more... (2004-08-19)
A cushion of air trapped under the rice fields of Senegal
Rice cultivation uses great volumes of water, especially where the submerged-field method involving surge flooding irrigation is practised. Maintenance of a layer of water on the soil surface throughout the cropping period usually favours its infiltration deeper down. However, it has been known for many years that in some regions water often does... view more... (2004-04-15)
