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)
New Pompeii before Pompeii discovered
Swedish archeologists have found previously unknown prehistoric settlements under ancient Pompeii. The Swedish Pompeii Project, tied to Stockholm University and the Swedish Institute in Rome, has worked for five seasons in a section of Pompeii to study and document the relics of the ancient city. When a well was emptied of its contents of pumice... view more... (2005-04-18)
Pitt Researchers Zero In on Ozone With Fluorescent Solution That Detects Harmful Molecule in the Air and Body
Researchers at the University of Pittsburgh have developed a fluorescent substance that glows bright green when exposed to even minute amounts of ozone in the air and in biological samples such as human lung cells. view more (2009-06-23)
New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five... view more... (2009-03-19)
Link between ozone air pollution and premature death confirmed
Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the US Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards. view more (2008-04-23)
Scientists in first global study of 'poison' gas in the atmosphere
It was used as a chemical weapon in the trenches in the First World War, but nearly a century later, new research by an international team of scientists has discovered that phosgene is present in significant quantities in the atmosphere. view more (2007-09-20)
Making bacteria make useful proteins
By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. view more (2009-09-08)
Oh, my aching back: Give me a shot of ozone
A minimally invasive interventional radiology treatment-that safely and effectively uses oxygen/ozone to relieve the pain of herniated disks-will become standard in the United States in the next few years, predict researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting. view more (2009-03-09)
NASA satellite eyes atmosphere to improve pollution and climate forecasting
Thanks to the latest sophisticated, satellite-based instruments, local and regional air pollution and their sources can now be observed closely from space. view more (2005-12-09)
Methyl bromide alternatives indicated for North Carolina tomato production
Methyl bromide (MeBr) is a highly effective broad-spectrum fumigant used extensively in U.S. agriculture to control a wide variety of pests. Under the Montreal protocol of 1991, however, MeBr was defined as one of the chemicals that contributed to the depletion of the stratospheric ozone layer, resulting in an incremental reduction in the amount... view more...

Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined control technology. This eliminates the main cause... view more... (2004-09-08)
U of M researchers unlock mystery of layer encircling the Earth's core
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth's core in a layer called the D'' region. view more (2006-01-31)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean uptake of greenhouse gases such as carbon dioxide... view more... (2003-11-21)
Air pollution from ships - a serious threat
Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the shores. Air pollution from ships may be twice as bad as... view more... (2004-03-30)
Stress management: X-rays reveal Si thin-film defects
Pile-ups, bad on the freeway, also are a hazard for the makers of high-performance strained-silicon (Si) semiconductor devices. view more (2006-07-10)
This idea doesn't stink: New tech cuts industrial odors, pollutants
A North Carolina State University researcher has devised a new technology that really does not stink. In fact, it could be the key to eliminating foul odors and air pollutants emitted by industrial chicken rendering facilities and - ultimately - large-scale swine feedlots. view more (2009-08-27)
Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants. view more (2008-02-28)
Ozone, nitrogen change the way rising CO2 affects Earth's water
Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. view more (2009-07-10)
