Scientists a step closer to producing fuel from bacteria
Scientists at the University of Sheffield have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future.   view more (2008-08-07)

Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined... view more (2004-09-08)

Nature's process for nitrogen fixation caught in action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life.   view more (2006-11-10)

Systems biology approach identifies nutrient regulation of biological clock in plants
Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status.   view more (2008-03-17)

Researchers confirm benzene-like electron delocalization of important molecule
Researchers in the lab of University of Oregon chemist Shih-Yuan Liu have successfully synthesized and structurally characterized boron-nitrogen compounds that are isoelectronic and isostructural to the fundamentally important benzene molecule.   view more (2008-06-20)

Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds.   view more (2008-03-13)

Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences.   view more (2006-04-11)

Will intensive forest practices impact water quality?
In order to increase productivity, forest practices have become more intense in recent decades. Forest fertilization increased by 800% in the southeastern United States from 1990 to 1999, and the total acreage fertilized in the Southeast exceeds the forest area fertilized in the rest of the world.   view more (2008-01-08)

Illinois research zeroing in on optimum soil nitrogen rates
A new study to evaluate the Illinois Soil N Test (ISNT) calls into question traditional soil fertility recommendations and promises a radical new soil-based approach that will benefit crop yields, the environment, and the bottom line for farmers.   view more (2005-09-01)

Cooking with gas may increase inflammatory activity in the lungs
Cooking with gas may increase inflammatory activity in the lungs, suggests a study in Occupational and Environmental Medicine. Teflon filters were used to collect any particulate matter pollution emitted from gas and electric cookers. The residue was then applied to cultured cells that normally... view more (2001-02-10)

Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is... view more (2004-06-21)

Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation.   view more (2005-06-07)

Carbon molecule with a charge could be tomorrow's semiconductor
Virginia Tech chemistry Professor Harry Dorn has developed a new area of fullerene chemistry that may be the backbone for development of molecular semiconductors and quantum computing applications.   view more (2008-09-09)

A rainbow of methods promises insights into biological processes and diseases
Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer.   view more (2007-05-02)

University of Oregon chemists discover new way to fix nitrogen
University of Oregon chemists have produced ammonia from nitrogen at room temperature under normal atmospheric pressure, marking a significant step toward achieving one of chemistry's coveted goals.   view more (2005-07-06)

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)

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... 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... view more (2008-07-22)

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... 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... view more (2002-04-15)
