Did life begin in a bubble?
Scientists in PEGG (Petroleum and Geochemistry Group) at the University of Plymouth have recently won two research grants totalling £114,000. The grants, awarded by the Natural Environment Research Council (NERC), are for research into the environmental effects of chemical discharges from oil... view more (2002-05-16)
Mother's prenatal stress predisposes their babies to asthma and allergy
Women who are stressed during pregnancy may pass some of that frazzlement to their fetuses in the form of increased sensitivity to allergen exposure and possibly future asthma risk. view more (2008-05-19)
Scientists find mercury threatens next generation of loons
A long-term study by the Wildlife Conservation Society, the BioDiversity Research Institute, and other organizations has found and confirmed that environmental mercury-much of which comes from human-generated emissions-is impacting both the health and reproductive success of common loons in the... view more (2008-03-05)
Italian study finds traffic pollution affects male fertility
A study by Italian researchers of motorway tollgate attendants has demonstrated that traffic pollution damages the quality of sperm in young and middle-aged men. In research published today (Wednesday 30 April) in Europe's leading reproductive medicine journal Human Reproduction[1] the research... view more (2003-04-26)
£350,000 Computer Boost for New Science Centre at University of Leicester
A new £350,000 supercomputer is set to make number crunching as nice as pi for mathematicians at the University of Leicester. The University has established a new Centre for Mathematical Modelling within the Faculty of Science and will link researchers in diverse disciplines such Physics,... view more (2000-11-07)
Reedbed technology for wastewater treatment:obtaining a better insight through modelling
Constructed wetlands: a green technology for integrated water management The quality of our Flemish surface waters has improved significant during the last decade. Nevertheless, in a densely populated area like Flanders we are still confronted with polluted surface water. The main reason for the... view more (2002-06-11)
Ozone shuts down early immune response in lungs and body
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria. view more (2007-10-01)
Bug hotels to treat toxic landfill run-off
A novel way to treat the noxious liquid that leaches out of landfill sites, using ‘bug hotels’, is being investigated by research engineers. Bug hotels are artificial havens for nitrogen-hungry bacteria, created by providing them with a comfortable habitat, warmth and food. The landfill... view more (2000-08-10)
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... view more (2005-02-25)
Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts. view more (2008-07-24)
Investigating causes of asthma attacks: New sensor system monitors environmental exposure
Researchers at the Georgia Tech Research Institute (GTRI) have developed a sensor system that continuously monitors the air around persons prone to asthma attacks. Worn in the pockets of a vest, the new system could help researchers understand the causes of asthma attacks. view more (2008-01-23)
Iowa State engineer develops laser technologies to analyze combustion, biofuels
Let's say a fuel derived from biomass produces too much soot when it's burned in a combustion chamber designed for fossil fuels. How can an engineer find the source of the problem? It originates, after all, in the flame zone of a highly turbulent combustion chamber. That's not exactly an easy place... view more (2007-12-06)
A Yeast Useful For Pollutant Removal Processes
Sugar refineries and distilleries produce effluent which is harmful for the environment. The sugar industry produces two tonnes of sugar cane bagasse (a straw-like material) for every tonne of refined sugar. For Cuba this translates into 10 to 20 million tonnes of bagasse per year. Distilleries,... view more (2002-06-27)
Mercury in atmosphere could be washed out more easily than earlier believed
Scientists for years have been at a loss to explain unexpectedly high levels of mercury in fish swimming the rivers and streams of areas like eastern Oregon, far away from industrial sources of mercury pollution such as coal-fired power plants. view more (2005-12-08)
Tiny holes will have huge telecomms impact
Tiny holes just thousandths of a millimetre in size look set to revolutionise the world of telecommunications within the next few years. As internet use grows and businesses and activities like electronic shopping become increasingly international, our need to be able to send vast quantities of... view more (2001-03-12)
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... view more (2004-03-30)

MIT: Prenatal arsenic exposure detected in newborns
MIT researchers have found that the children of mothers whose water supplies were contaminated with arsenic during their pregnancies harbored gene expression changes that may lead to cancer and other diseases later in life. view more (2007-11-26)
Diesel exhaust fumes affect people with asthma, finds study on London's Oxford Street
Diesel exhaust fumes on polluted streets have a measurable effect on people with asthma, according to the first study looking at exhausts and asthma in a real-life setting, published on 6 December in the New England Journal of Medicine. view more (2007-12-06)
Mountainous plateau creates ozone 'halo' around Tibet
Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study from University of Toronto researchers. view more (2005-12-08)
Central American fires impact US air quality and climate
Scientists using NASA satellites and computer models have shown that pollutants from Central American biomass burning can influence air quality and climate in the United States. view more (2006-10-11)
UCLA study links air pollution to clogged arteries
Got high cholesterol? You might want to stay away from air pollution. That's the message of a new UCLA study linking diesel exhaust to atherosclerosis, or hardening of the arteries, which significantly increases one's risk for heart attack and stroke. view more (2007-07-26)
Green Algae Step on the Gas
Whether it is in the shape of bread rolls, crunchy flakes or 'spaghetti al pesto di mare', the food industry is on an 'algae trip', selling these marine flora to health-conscious consumers as delicious energy-rich additions to their products. Yet there is another way that algae can help us to solve... view more (2001-12-13)
Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes. view more (2008-10-10)
Soil emissions are much-bigger-than-expected component of air pollution
