New theory on largest known mass extinction in the history of the earth
Did volatile halogenated gases from giant salt lakes at the end of the Permian Age lead to a mass extinction of species? view more (2009-03-31)
Fire resistant plastics
The use of halogenated flame retardants in plastics is steadily declining because they are volatile, pose an environmental risk and are difficult to recycle. Microcapsules, fibers and melamine resin foams represent some of the chief alternatives. view more (2002-02-01)
Science makes waste less smelly
Every day, great quantities of domestic and industrial waste are put into landfill sites, covered over and left to rot. As this waste decomposes, it gives off a complicated mixture of gases, some of them poisonous and some of them smelly, often for several decades after a site is closed. As well as being unpleasant for near neighbours, landfill... view more... (2001-03-13)
Greenhouse Gases - Nothing To Blame For?
In the nearest future we may witness global cooling in spite of increasing concentration of greenhouse gases in the atmosphere. That can happen, if the following hypothesis is correct: not the growth of greenhouse gases concentration provokes temperature to rise, but vice versa. It is generally believed nowadays that greenhouse gases are... view more... (2004-07-30)
Occupational exposure to anaesthetic gases associated with tripling of risk of multiple sclerosis
Occupational exposure to anaesthetic gases may triple the risk of multiple sclerosis, finds a study of nurses in Occupational and Environmental Medicine. view more (2002-12-17)
Female vets at risk of miscarriage from anesthetic gases and pesticides
Female vets run twice the risk of miscarriage as a result of exposure to anaesthetic gases and pesticides, suggests a study published ahead of print in Occupational and Environmental Medicine. view more (2008-04-03)
Scrubbing sulfur
The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. view more (2009-08-18)
Toward the design of greener consumer products
So you're a manufacturer about to introduce a new consumer product to the marketplace. Will that product or the manufacture of the product contribute to global warming through the greenhouse effect? view more (2009-09-17)
Volcanic aerosol clouds and gases lead to ozone destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford. view more (2006-11-09)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. view more (2006-05-11)
Biodiesel won't drive down global warming
EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. view more (2007-04-23)
Shift toward services industries won't end global warming
The shift toward a service-based economy won't automatically reduce the amount of greenhouse gases (GHS) in the air, a University of Minnesota researcher has found. His research contradicts assumptions about global warming often preferred by some economists and national policy experts. view more (2006-11-02)
Researchers at the University Jaume I put environmentally-friendly refrigerants to the test
Keeping food cool in the fridge or switching on the air conditioning at the office can be costly for the environment. The gases that have been used up till now for refrigeration (mainly the so-called HCFCs, such as R22) contain high proportions of chlorine, one of the elements responsible for the depletion of atmospheric ozone. Manufacturing new... view more... (2004-06-28)
Safe Heating of Explosive Gases
The Institut für Mikrotechnik Mainz GmbH (IMM) has developed the micro structured gas heater MSGH for combustible or explosive media. A clear separation of the space containing the medium from the heating elements allows safe heating and overheating of process gases, gas mixtures or gas/vapour mixtures. The MSGH has 50 cubic centimetres of... view more... (2004-06-23)
Innovative System For Testing Tunnel Safety
LABEIN Tecnological Centre, based in the Basque Country, has developed an innovative system for verifying tunnel safety in the case of fire. The new system, developed at the request of the Gipuzkoa Provincial Government, has been successfully tested in the new Lezarri (Bergara) tunnel on the A1 Eibar-Vitoria motorway. The novel element in the... view more... (2004-01-22)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

Voyager data may reveal trajectory of solar system
Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets. view more (2006-05-31)
Denver to Barcelona: Global cities and greenhouse gas emissions
Denver released the largest amount of greenhouse gases (GHG) and Barcelona the smallest amount in a new study documenting how differences in climate, population density and other factors affect GHG emissions in global cities. view more (2009-09-24)
What goes down, must come up: Earth's leaky mantle
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation. view more (2009-05-28)
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)
