Denitrification, its importance once diluted, may be back on top, Princeton-led team says
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. view more (2009-09-03)
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 light helps symbiont bacteria associate with plants to fix nitrogen
Certain leguminous plants which live in rice fields have the exceptional feature of forming nitrogen-fixing nodules on their stem surfaces. These contain symbiotic bacteria capable of using light as an energy source. Although it had been suspected that bacterial photosynthesis played a role in this highly particular nitrogen-fixing symbiosis,... view more... (2001-01-26)
Marine bacterium suspected to play role in global carbon and nitrogen cycles
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. view more (2005-09-23)
Sowing a future for peas
New research from the John Innes Centre and the Central Science Laboratory could help breeders to develop pea varieties able to withstand drought stress and climate change. view more (2008-09-17)
When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Commercial interests driving standards for formula milk
Commercial interests may be the strongest driver of what goes into formula milk, warn child health experts in this week's BMJ. view more (2006-03-17)
Mystery Solved: Marine Microbe Is Source of Rare Nutrient
A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about the source of an essential nutrient in the ocean. view more (2009-09-30)
Large source of nitrate, a potential water contaminant, found in near-surface desert soils
A UC Riverside-led study in the Mojave Desert, Calif., has found that soils under "desert pavement" have an unusually high concentration of nitrate, a type of salt, close to the surface. Vulnerable to erosion by rain and wind if the desert pavement is disrupted, this vast source of nitrate could contaminate surface and groundwaters,... view more... (2008-03-03)
New method for detecting nitroxyl will boost cardiac drug research
Wake Forest University scientists have developed a new research tool in the pursuit of heart medications based on the compound nitroxyl by identifying unique chemical markers for its presence in biological systems. view more (2009-07-06)
Fat still on the children's menu
Parents should think twice before offering a low-fat menu to youngsters, despite concerns over obesity. view more (2007-08-16)
Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder. view more (2006-06-21)
A new plant-bacterial symbiotic mechanism promising for crop applications
The growth of most plants depends on the presence of sufficient amounts of nitrogen contained in the soil. However, a family of plants, the legumes, is partially free of this constraint thanks to its ability to live in association with soil bacteria of the Rhizobium, genus, capable of fixing nitrogen from the air. view more (2007-06-06)
The Universe, seen under the Gran Sasso mountain, seems to be older than expected
Some nuclear fusion reactions inside stars occur more slowly than we thought and, as a consequence, stars themselves, as well as galaxies and the entire universe are a bit older than expected. This is what comes out from the last results of Luna experiment (Laboratory for Underground Nuclear astrophysics), settled by National Laboratories of Gran... view more... (2004-05-13)
Tunguska catastrophe: Evidence of acid rain supports meteorite theory
The Tunguska event is regarded as one of the biggest natural disasters of modern times. On 30 June 1908 one or more explosions took place in the area close to the Tunguska River north of Lake Baikal. The explosion(s) flattened around 80 million trees over an area of more than 2000 square kilometres. view more (2008-07-16)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
Warplane system could cut mid-air explosion
AIRLINES are facing fresh calls for their aircraft`s fuel tanks to be fitted with explosion-prevention systems like those on military planes. This follows a warning from Boeing that 3200 of its planes may have faulty fuel pumps that could spark explosions. Boeing says a spark from wiring in the pumps could ignite vapour in a near-empty tank. The... view more... (2002-10-02)
Are comets at the origin of life on earth ?
For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great... view more...

Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
Key new ingredient in climate model refines global predictions
For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. view more (2009-10-12)
