Caltech researchers reveal unexpected sources of nitrogen fixation
Researchers at the California Institute of Technology (Caltech) have identified an unexpected metabolic ability within a symbiotic community of microorganisms that may help solve a lingering mystery about the world's nitrogen-cycling budget. view more (2009-10-16)
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 leachate can be pumped through these... view more...

WHEN AN EARTHWORM DOES AS MUCH DAMAGE TO SOILS AS A BULLDOZER
The transformation of wet tropical forest into pastures causes profound changes in the physical structure of soils by favouring compaction. Such densification asphyxiates the soil. It is generally attributed to the compression caused by heavy machinery used for deforestation and in the creation of pastures and subsequently to trampling by cattle.... view more... (1999-05-11)
Interactions with aerosols boost warming potential of some gases
For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate. view more (2009-10-30)
No laughing matter -- bacteria are releasing a serious greenhouse gas
Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously. view more (2008-03-31)
Managing Carbon Loss
As the United States continues to develop alternative energy methods and push towards energy independence, cellulosic-based ethanol has emerged as one of the most commercially viable technologies. view more (2008-12-04)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Analysis of Lake Washington microbes shows the power of metagenomic approaches
Today's powerful sequencing machines can rapidly read the genomes of entire communities of microbes, but the challenge is to extract meaningful information from the jumbled reams of data. view more (2008-08-18)
An invisible threat could change Britain's landscapes
People and farm animals are helping an invisible pollutant to change the types of plants that grow in Britain, particularly in remote and rural regions such as the Lake District. view more (2005-02-11)
Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. view more (2005-12-20)
Another first for Europe: an electric car with extended range and no pollution
The international symposium takes place in Brussels from 29 September to 3 October and has been organised by the Commission on the topic "A future for the city". Some 1 500 specialists in electric and hybrid vehicles are expected to attend to see the latest technological developments designed to improve this mode of transport during the coming... view more...

Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. view more (2008-12-10)
Prepare CO2 capture and storage now for greater environmental benefit later
CO2 capture and storage can make a major contribution to CO2 reduction in the Netherlands. By the mid-21st century 80 to 110 million tonnes of CO2 per year could be avoided in the sectors energy, industry and transport. This is half of the current CO2 emission. Moreover, this can be realised against acceptable costs concludes Dutch researcher Kay... view more... (2007-04-16)
EU research drive to reduce air pollution from traffic
Today the EU signed an agreement with the USA, Japan and China to address air pollution from transport. Signed during a conference in Milan, the accord will allow for joint research on emissions and vehicle testing, and it foresees the creation of a common scientific platform to measure and benchmark air pollution from traffic. The joint effort... view more... (2003-12-10)
Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
Computer model helps combat air pollution across Europe
The key role of multidisciplinary research in developing a landmark intergovernmental strategy to combat air pollution across Europe will be considered by Professor Helen ApSimon of Imperial College London in her inaugural lecture, A lot of Hot Air - Transboundary Air Pollution Over Europe. view more (2003-01-28)
NASA's Cassini Reveals Lake-Like Feature on Titan
Scientists are fascinated by a dark, lake-like feature recently observed on Saturn's moon Titan. NASA's Cassini spacecraft captured a series of images showing a marking, darker than anything else around it. It is remarkably lake-like, with smooth, shore-like boundaries unlike any seen previously on Titan. view more (2005-06-29)
Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor. view more (2005-09-08)
Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths. view more (2006-06-21)
Red sky at night -- astronomers delight
A collaboration of over 50 astronomers, The IPHAS consortium, led from the UK, with partners in Europe, USA, Australia, has released the first comprehensive optical digital survey of our own Milky Way. view more (2007-12-11)
