Dolphins Speak With Half-Nose
Russian researchers have recorded the sounds audible only inside the right part of the dolphin's nasal passage. Animals produce them during echolocation. This research can shed light on how the cetacea produce ultrasonic signals. Researchers of the Severtsov Institute of Ecology and Evolution Problems, Russian Academy of Sciences, have obtained... view more... (2004-11-01)
Mirror Measures Vortex Drag
Airplanes generate trailing wake vortices which can be dangerous for following aircraft, especially on takeoff and landing. An onboard laser measuring device scans the air space in front of the plane, recognizes turbulence and will inform the pilot. The volume of air traffic is constantly rising - many air routes are already overloaded. Frequent... view more... (2004-07-08)
Key component of debilitating lung disease identified
For the first time, researchers have demonstrated a close correlation between the decline in a key component of the lung's antioxidant defense system and the progression of chronic obstructive pulmonary disease (COPD) in humans. view more (2008-09-12)
Revolutionary room-specific air-filtering of pollutants, nerve gases and viruses
VTT Technical Research Centre of Finland and Lifa Air Oy Ltd have jointly developed a room filter that traps particles, toxic gases, bacteria and viruses in the incoming air. Low-priced and energy-efficient, the filter can be fitted in the existing air-conditioning systems. Room-specific filtering of inlet air has been attracting increasing... view more... (2003-10-20)
Micro-organisms in salt lakes produce chlorinated air pollutants - Discovery of a new natural factor in desertification: Micro-organisms in salt lakes.
Salt lakes have a greater impact on climate change than was previously understood. This has been established by scientists from the UFZ Centre for Environmental Research (Umweltforschungszentrum Leipzig-Halle) together with colleagues from Austria, Russia and South Africa. They found evidence that bacteria in salt lakes produce substances which... view more... (2005-02-25)
MEASURING THE HEALTH COSTS OF POLLUTION (pp 782, 795)
Research in this week's issue of THE LANCET concludes that the public-health consequences of air pollution are considerable, with traffic-related air pollution remaining a key target for public-health action in Europe. Previous research over the past two decades has shown that air pollution contributes to death and illness, with some effects... view more... (2000-08-30)
Biosolids Microbes Pose Manageable Risk to Workers
Class B biosolids are sewage sludges that have been treated to contain fewer than 2.0 x 106 fecal coliforms/dry gram. view more (2008-10-28)
Exposures to metals and diesel emissions in air linked to respiratory symptoms in children
Exposure shortly after birth to ambient metals from residential heating oil combustion and particles from diesel emissions are associated with respiratory symptoms in young inner city children. view more (2009-11-24)
Cool, air blown under football shoulder pads reduces body temperature and heart rate, research finds
Cool, dry air flowing between the athlete and their football pads reduces core body temperature and heart rate dramatically, thereby reducing the likelihood of heat-related illness. view more (2008-07-10)
Study recommends new guidelines for air bag safety in children
Children 14 and younger should not sit in the front passenger seat of cars equipped with air bags, according to a new study by an emergency medicine researcher at Oregon Health & Science University's Doernbecher Children's Hospital. view more (2005-06-06)
Asthma epidemics linked to airflow patterns in thunderstorms
It's the airflow patterns in thunderstorms, rather than the electrical activity, thunder, or rain, which trigger asthma epidemics, concludes research in Thorax. The hospital admission rates for asthma and airflow patterns during thunderstorms up to 80 km away were studied for six towns in south eastern Australia between 1995 and 1998. Hourly... view more...

Lords Call For Action On Air Travel and Health
There must be changes in the regulation and management of the air travel industry – accompanied by urgent research – if passenger and crew health is to be properly safeguarded. This call is made today in a Report by the House of Lords Science and Technology Committee – Air Travel and Health. The Report follows an Inquiry against... view more... (2000-11-22)
Air pollution damages plants
If you live in a large town or city, have you ever wondered why some plants do not grow well in your garden, despite your best efforts? It is, in part, because of air pollution. At a symposium on the biology of air pollution hosted by the Institute of Biology this week in London, delegates heard from experts about the effects of pollutants on... view more... (1999-10-27)
Venous thrombosis after travel
Traveling for more than 4 hours by air, car, bus or train is associated with an increased risk of venous thrombosis. view more (2006-08-22)
A new, dechlorinating bacterium
Several industrial activities of the previous decades resulted in serious contamination of groundwater. For instance, polyvinyl chloride (PVC) production and related activities cause annual underground releases of 137 tonnes of 1,2-dichloroethane (1,2-DCA) in the USA (1988-1999). The latter molecule has an environmental half-life of about 50... view more... (2003-04-22)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
Safer skies for the flying public
University of Texas professor Constantine Caramanis and colleagues at the Massachusetts Institute of Technology (MIT) are working on a air traffic decision-making system that rapidly adapts its flight recommendations without human input based on thousands of changing variables. view more (2008-09-04)
Gone With the Wind? Over A Hundred Scientists Take To The Skies To Track Global Air Pollution
This morning a team of forty scientists from seven UK universities will travel to the Azores to join hundreds more in the largest international atmospheric field campaign of its type ever attempted. The exciting mission will track and investigate a mass of polluted air as it leaves the United States and travels across the Atlantic to the UK and... view more... (2004-07-08)
Medical acupuncture gaining acceptance by the US Air Force

Air Rather Than Oxygen For Babies Requiring Ventilation After Delivery (pp 1293, 1329)
Provision of air rather than 100% oxygen for babies requiring ventilation after delivery could reduce infant mortality, suggests a study in this week's issue of THE LANCET. The finding is counter to the long-held belief that 100% oxygen is better than air for babies requiring ventilation in the first few minutes of life. view more (2004-10-06)
