Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began. view more (2007-10-30)
Scientists: As rainfall changes, tropical plants may acclimate
Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows. view more (2007-05-08)
Nitrogen in the air feeds the oceans
A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow? view more (2005-08-11)
Robust sensor yields cleaner car exhaust
Emissions from cars have to be reduced further in order to meet today's environmental demands. A new and robust exhaust sensor developed by researchers at Linköping University in Sweden has proven to meter the consistency of exhaust gases extremely well and is now on its way to the market. view more (2005-04-27)
Pesticides choke pathway for nature to produce nitrogen for crops
Many farmers applying pesticides to boost crop yields may instead be contributing to growth problems, scientists report in a new study. view more (2007-06-06)
Air pollution affects respiratory health in children with asthma
A new study reports that inner-city children with asthma may be particularly vulnerable to air pollution at levels below current air quality standards. view more (2008-04-16)
Water acts as catalyst in explosives
The most abundant material on Earth exhibits some unusual chemical properties when placed under extreme conditions. view more (2009-03-23)
Particle physics fights terrorism
Scientists have developed a detector for plastic explosives. A consortium of scientists from Imperial College, other universities and industy have created the detector, which uses neutrons and is based on technologies developed for the Large Hadron Collider at CERN, Geneva. The technique overcomes problems with other devices that can confuse - for... view more... (1997-11-03)
Researchers find key to saving the world's lakes
After completing one of the longest running experiments ever done on a lake, researchers from the University of Alberta, University of Minnesota and the Freshwater Institute, contend that nitrogen control, in which the European Union and many other jurisdictions around the world are investing millions of dollars, is not effective and in fact, may... view more...

Fish Blood Preserves Sperm
In the Arctic and Antarctic seas the water gets cold to minus 1.9 C in winter, but somehow some fish live there. These cold-blooded creatures survive in the icy water because the blood in their veins contains antifreeze proteins and glycoproteins. High levels of the antifreeze proteins are found in the blood serum, they are present in cell... view more... (2002-06-04)
New hope for landmine detection
The first steps in a new method of detecting landmines by determining the presence of tiny quantities of the explosive TNT (trinitrotoluene) are described in research published today in the Institute of Physics publication Journal of Physics D. Markus Nolte, Alexei Privalov and Franz Fujara of Darmstadt Technical University in Germany, together... view more... (2002-04-15)
Gassed by gannets!
This is one of the subjects being investigated in the GANE (Global Atmospheric Nitrogen Enrichment) research initiative funded by NERC. The first meeting of the principal investigators will be on Thursday, 9th March, when they will share information on progress of the various projects that form the initiative. view more (2000-03-08)
A common genetic mechanism discovered in nitrogen-fixing plants
Some soil microorganisms are capable of forging associations with plant roots in the form of symbioses. Certain of these relationships play a highly important ecological and agronomic role. view more (2008-03-11)
Healthy rivers needed to remove nitrogen
Healthy streams with vibrant ecosystems play a critical role in removing excess nitrogen caused by human activities, according to a major new national study published this week in Nature. view more (2008-03-13)
Bangladesh to dramatically expand technology that doubles efficiency of urea fertilizer use
The Government of Bangladesh has announced that it will expand urea deep placement (UDP)-a technology that doubles the efficiency of urea fertilizer use-to almost 1 million hectares (ha) of rice land, reaching about 1.6 million farm families, in the coming boro or dry season. view more (2007-12-19)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached molecules. view more (2007-04-13)
UC Santa Barbara researchers light up 'dark' spins in diamond
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins - an initial step towards... view more...

Cropland diversity reduces nitrogen pollution
Researchers have identified a link between the diversity of crops grown in farmlands and the pollution they create in lakes and rivers. view more (2009-02-11)
UCI scientists discover ozone-boosting chemical reaction
Burning of fossil fuels pumps chemicals into the air that react on surfaces such as buildings and roads to create photochemical smog-forming chlorine atoms, UC Irvine scientists report in a new study. view more (2009-07-21)
ORNL study finds rivers play part in removing nitrogen
Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature. view more (2008-03-13)
