Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species. view more (2008-10-07)
Keeping the environment clean with compressed air
Savings of up to 50 per cent possible / 320 000 compressors currently in use EU-wide / Complex management structures Annually, the production of compressed air accounts for about 10 per cent of total industrial electricity consumption in the European Union. This corresponds to over 80 billion kilowatt hours per year. In spite of this high figure,... view more... (2001-03-02)
USC study finds big air pollution impacts on local communities
Heavy traffic corridors in the cities of Long Beach and Riverside are responsible for a significant proportion of preventable childhood asthma, and the true impact of air pollution and ship emissions on the disease has likely been underestimated, according to researchers at the University of Southern California (USC). view more (2009-11-05)
Secondhand smoke a risk for children worldwide
Parents worldwide are doing little to protect their children from exposure to secondhand smoke, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2008-03-06)
Heat dangers forgotten in the battle against air pollution
UCL scientists warn that amidst all the concerns over air pollution, the more basic health message of 'staying cool when the weather is hot' may be being forgotten. view more (2005-10-12)
Wind tunnel tests could lead to healthier towns and cities
It's hardly an appealing thought but the overpowering fragrance of mothballs in a large wind tunnel could provide the key to improving air quality in our towns and cities. The tests will improve our understanding of how pollution and heat behave at street level so that more effective ventilation methods can be developed. The research will be... view more...

Air pollution increases infants' risk of bronchiolitis
Infants who are exposed to higher levels of air pollution are at increased risk for bronchiolitis, according to a new study. view more (2009-11-06)
Clear view of the clouds will bring better weather forecasts
Accurately forecasting rain will be easier thanks to new insights into clouds from a study led by the University of Leeds and UCL (University College London). view more (2005-08-11)
Research removes major obstacle from mass production of tiny circuits
As they eliminate tiny air bubbles that form when liquid droplets are molded into intricate circuits, a Princeton-led team is dissolving a sizable obstacle to the mass production of smaller, cheaper microchips. view more (2007-01-18)
Automating heating and ventilation
Homeowners looking to save heating costs can find themselves in a quandary. If they apply too much insulation to the outside walls and install airtight windows, the inflow of fresh air from outside is reduced. To prevent stale and humid air from causing mold to grow, approximately half of the air volume should be renewed every hour. But... view more... (2003-01-23)
Study of toxins in Houston air warrants new standards
A new report recommends immediate action to reduce levels of four toxic air pollutants because exposure to them poses a high risk to community health. view more (2006-09-28)
Flowers' fragrance diminished by air pollution, University of Virginia study indicates
Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates. view more (2008-04-11)
Meat-eating dinosaur from Argentina had bird-like breathing system
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system. view more (2008-09-30)
Solution to hospital infections could be in the air
A breakthrough in the fight against infections acquired in hospital could be achieved thanks to pioneering new research. The project is investigating the use of ionisers to eradicate airborne infections in hospitals - a technique that could deliver major health benefits and financial savings. Starting in December, the 3-year initiative will be... view more... (2003-12-01)
54 per cent of air passengers experience significant reductions in oxygen levels
More than half of air travellers find that their oxygen saturation drops to a level at which many hospital patients would be prescribed extra oxygen, according to a paper in the May issue of Anaesthesia. view more (2005-04-25)
Documenting a paradox: smoke decreases rainfall but ultimately increases its intensity
Air pollution and smoke suppress rainfall, but cause the remaining rain amounts to fall in greater intensities, with lightning and hail, says a researcher at the Hebrew University of Jerusalem. The researcher, Prof. Daniel Rosenfeld, was one of a group of scientists that included also participants from Germany, Sweden and Brazil who conducted... view more... (2004-02-25)
Tiny future for military aircraft
Scientists are looking to nature to help them develop an aeroplane the size of a bee, which could have a significant effect upon civilian life and modern warfare. Researchers from the University of Bath are undertaking research into the aerodynamics needed to fly very small unmanned aircraft that can be used in a variety of operations. These... view more...

Carnegie Mellon researchers apply new statistical test
Carnegie Mellon University's Cliff I. Davidson, Joseph B. Kadane and Nanjun Chu have found that polluted air in the highly populated East End areas of Pittsburgh are more affected by major sources to the city's southeast than previously thought. view more (2009-03-18)
Toxic chemicals found in common scented laundry products, air fresheners
A University of Washington study of top-selling laundry products and air fresheners found the products emitted dozens of different chemicals. All six products tested gave off at least one chemical regulated as toxic or hazardous under federal laws, but none of those chemicals was listed on the product labels. view more (2008-07-24)
Ozone levels drop when hurricanes are strengthening
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, NASA-funded scientists from Florida State University looked at ozone around hurricanes and found that ozone levels drop as a hurricane is intensifying. view more (2005-06-08)
