Fires in Alaska and Canada caused sharp increase in Houston's ozone level
Forest fires that ravaged parts of eastern Alaska and western Canada in 2004 exacerbated the already-high levels of ozone pollution in Houston, Texas, some 5,000 kilometers [3,000 miles] away.   view more (2006-09-25)

Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and... view more (2000-05-10)

Researchers mimic lotus leaves for self-cleaning PV arrays, non-stick MEMS
Researchers at the Georgia Institute of Technology are mimicking one of Nature's best non-stick surfaces to help create more reliable electric transmission systems, photovoltaic arrays that retain their efficiency, MEMS structures unaffected by water and improved biocompatible surfaces able to... view more (2006-10-16)

A Planet in Progress?
Scientists are one step closer to understanding how new planets form, thanks to research funded by the National Science Foundation (NSF) and carried out by a team of astrophysicists at the American Museum of Natural History.   view more (2008-03-27)

Indoor air purifiers that produce even small amounts of ozone may be risky for health
In a small, poorly ventilated room, an indoor air purifier that produces even a few milligrams of ozone per hour can create an ozone level that exceeds public health standards.   view more (2006-05-10)

Light echoes whisper the distance to a star
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder.   view more (2008-02-11)

UNH Researchers Test Sediment-Scrubbing Technology In Cocheco River
In a mud flat at the edge of the Cocheco River, just outside downtown Dover, scientists from the University of New Hampshire's Contaminated Sediments Center are testing an innovative way to treat polluted sediment in coastal waterways.   view more (2008-06-18)

Daily or weekly use of paracetamol linked to asthma
The use of aspirin and paracetamol was compared in 664 asthmatics and 910 people without asthma over a period of 12 months. The study participants were aged between 16 and 49, and drawn from 40 general practices in South London. Information on potential risk factors for asthma, such a smoking and... view more (2000-03-17)

Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the... view more (2002-10-29)

Media Invitation: Urban environment in the context of EU enlargement: European research helps cities to solve common problems
WHAT? 80% of Europeans are living in cities, confronted to major environmental and social challenges in a daily basis. European Commission is organising a Conference on "Sustainable urban management and Land Use" to assess the results of this area of research so far, to transfer best... view more (2004-06-22)

World needs climate emergency backup plan, says expert
In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan.   view more (2008-11-10)

At that star, turn left!
Our bodies contain proteins that are made of smaller molecules that can be either left- or right-handed, depending upon their structure. Regardless of which hand we use to write, however, all human beings are `left-handed` at the molecular level. Life on Earth uses the left-handed variety and no... view more (2002-10-17)

AGU Journal European highlights - 30 October 2002

HEARTS AND MINDS BENEFIT FROM £71M SCIENCE BOOST
Research into heart disease and the workings of the human brain are amongst the projects to benefit from £71m in grants for British science announced today by Science Minister Lord Sainsbury. Grants totalling £24m have been awarded to 14 research projects at 12 universities across the... view more (2001-04-10)

NASA's 'Deep Impact' Team Reports First Evidence of Cometary Ice

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)

Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades
Growing desertification worldwide threatens to swell by millions the number of poor forced to seek new homes and livelihoods. And a rising number of large, intense dust storms plaguing many areas menace the health of people even continents away, international experts warn in a new report.   view more (2005-06-16)

Colossal Black Holes Common in the Early Universe
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and... view more (2008-10-17)

Polarizing filter allows astronomers to see disks surrounding black holes
For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be.   view more (2008-07-24)

Study links cat disease to flame retardants in furniture and to pet food
A mysterious epidemic of thyroid disease among pet cats in the United States may be linked to exposure to dust shed from flame retardants in household carpeting, furniture, fabrics and pet food, scientists are reporting in a study scheduled for publication the Aug. 15 online issue of Environmental... view more (2007-08-16)
