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)

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)

New findings blow a decade of assumptions out of the water
The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic.   view more (2007-01-11)

A Little Nitrogen Can Go a Long Way
Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good... view more (2008-09-04)

Ecosystem of vanishing lake yields valuable bacterium
In the salt flats near a slowly vanishing lake, a team of researchers have found never-before-seen bacterium that could clean up some of humanity's pollution.   view more (2006-10-18)

Evolving designer ecosystem sheds light on unintended consequences
Amidst the semi-arid stretches of Phoenix, a visitor might blink twice at the sight of a sailboat cutting across the horizon. Tempe Town Lake, on the northern edge of Arizona State University (ASU), is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water... view more (2008-09-04)

Elevated nitric oxide in blood is key to high altitude function for Tibetans
How can some people live at high altitudes and thrive while others struggle to obtain enough oxygen to function?   view more (2007-10-31)

Fat overrides effects of vitamin C
Fats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential... view more (2007-04-02)

Organic farming produces same corn and soybean yields as conventional farms, but consumes less energy and no pesticides, study finds
Organic farming produces the same yields of corn and soybeans as does conventional farming, but uses 30 percent less energy, less water and no pesticides, a review of a 22-year farming trial study concludes.   view more (2005-07-14)

Alternatives to the use of nitrate as a fertiliser
In order to develop sustainable agricultural production, what is required is a study of nitrogenated sources as alternatives to the nitrates that predominate in agricultural soils and that have a greater contaminant capacity.   view more (2006-04-19)

Air monitoring helps anticipate possible ecosystem changes
When rain settles the atmosphere and brings air pollutants to the ground, it can have a lasting effect on ecosystems, sometimes hundreds of miles away, according to a Texas AgriLife Research agricultural engineer.   view more (2008-06-26)

Peptic ulcer surgery increases the risk of pancreatic cancer
Peptic ulcer surgery seems to increase the risk of developing pancreatic cancer, finds research in the Journal of Clinical Pathology.   view more (2002-04-25)

Nano design adjustment may help find, clear some water contaminants
Experiments designed to test discrepancies in theoretical computational chemistry have turned up a barely two-angstrom difference that may lead to a new approach to locate and remove dangerous toxins such as perchlorate and nitrates from the environment.   view more (2006-12-14)

Action of nitroglycerin for chest pain may place some patients at risk
Definitive evidence to explain how the drug nitroglycerin relieves chest pain has resulted from a new study by Howard Hughes Medical Institute investigators at Duke University Medical Center.   view more (2005-08-16)

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)

Great Plains' historical stability vulnerable to future changes
A survey of long-term trends in population, farm income, and crop production in the agricultural Great Plains concludes that threats to society and the environment are counterbalanced by "surprising stability" and the potential for short- and medium-term sustainability.   view more (2007-10-01)

Digital communications advance with simple CdS thin films
Demands on digital communications are increasing at an exponential rate. The need for innovative advances in this area means research on optical and electrical properties of CdS thin films are of interest.   view more (2006-05-15)

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)

High-risk patients need better guidance on what is and isn't a heart attack
Varying advice means patients at high-risk of having a heart attack are unclear about when symptoms are potentially life threatening and when they should call an ambulance, argue a group of heart specialists in this week's BMJ.   view more (2007-07-09)

Conception date affects baby's future academic achievement
Does the time of year in which a child is conceived influence future academic achievement? Yes, according to research by neonatologist Paul Winchester, M.D., Indiana University School of Medicine professor of clinical pediatrics. Dr. Winchester, who studied 1,667,391 Indiana students, presents his... view more (2007-05-07)

Flowers' fragrance diminished by air pollution, University of Virginia study indicates
Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates.   view more (2008-04-11)

Cerium oxide nanotubes get noticed
Chemists and materials scientists often study "nanotubes" - capsule-shaped molecules only a few billionths of a meter (nanometers) in width.   view more (2006-03-29)

Virus decimates algal blooms
As soon as the pest algae run out of nutrients, viruses attack and abruptly end the algal bloom. This is revealed in a three-year international study under the leadership of the Netherlands Institute for Sea Research. This knowledge opens up opportunities for using natural enemies to remove algal... view more (2002-11-15)

Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species.   view more (2008-10-07)

University of Oregon researcher finds that on water's surface, nitric acid is not so tough
Nitric acid is a notoriously strong and chemically destructive compound found in water on earth and in our atmosphere. However, a team of researchers have found that its punch is much weaker when it sits on the top of a water surface.   view more (2007-08-21)
