Study assesses impact of fish stocking on aquatic insects
The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. view more (2009-03-27)
Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. view more (2008-04-25)
Round Goby invade Great Lakes
Canadian scientists uncover alarming invasion of round goby into Great Lakes tributaries: impact on endangered fishes likely to be serious. view more (2009-08-12)
Deep-sea species' loss could lead to oceans' collapse, study suggests
The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. view more (2007-12-28)
Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages. view more (2006-06-23)
Climate change and species distributions
Scientists have long pointed to physical changes in the Earth and its atmosphere, such as melting polar ice caps, sea level rise and violent storms, as indicators of global climate change. view more (2008-08-04)
Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial. view more (2007-05-10)
Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how... view more... (2003-03-13)
Catastrophic shift in species diversity and productivity of an ecosystem
Ecology and environmental management is largely predicated on the view that ecosystems respond to environmental changes in a smooth and straightforward way. However, in Ecology Letters, May, Schmitz reports on a long-term field experiment that may prompt a hard, critical look at this reigning view. In the experimental system, top predators... view more... (2004-05-04)
Iron 'snow' helps maintain Mercury's magnetic field, scientists say
New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground. view more (2008-05-08)
Educational inequality major factor in lack of social cohesion
The UK is falling behind the Netherlands, Denmark and Norway in its efforts to create a more cohesive society according to new research from the Institute of Education. Education, Equity and Social Cohesion: A Distributional Model by Andy Green, John Preston and Ricardo Sabates finds greater inequality in educational outcomes and skills in... view more...

Nitrogen pollution boosts plant growth in tropics by 20 percent
A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen pollution. view more (2008-02-07)
University of Nevada professor demonstrates new hydrogen fuel system
Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon. view more (2007-02-23)
Genetic hearing loss may be reversible without gene therapy
Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon. view more (2007-02-23)
Erosion rates double along portion of Alaska's coast
Skyrocketing coastal erosion occurred in Alaska between 2002 and 2007 along a 64 kilometer (40 mile) stretch of the Beaufort Sea, a new study finds. The surge of erosion in recent years, averaging more than double historical rates, is threatening coastal towns and destroying Alaskan cultural relics. view more (2009-02-19)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
Environmental lessons from tsunami as world's coastal population doubles
Coastal populations and ecosystems are more likely to bounce back from extreme coastal disasters by protecting local environments and building on local knowledge, according to a report published in Science. view more (2005-08-12)
Changing ocean conditions led to decline in Alaska's sea lion population
A new study out of Alaska points out the impacts of climate change on marine ecosystems, and the need for increased research and stronger science based management to address future concerns. view more (2007-03-23)
Bacteria for plague control in agriculture
Bacillus thuringiensis, a spore bacteria discovered in 1901 by the Japanese scientist Ishiwata and, ten years later, by the German scientist Berliner came across his findings. It is the micro-organism most used as a bio-insecticide throughout the world. It is a bacterium found naturally in ecosystems, frequently on floors and on the surface of... view more... (2003-02-14)
Ericsson head named honorary doctor at Lule'å
For his "ability, in his leadership, to turn technology into business in the stiffest possible international competition," Carl-Henric Svanberg has been awarded an honorary doctorate at Lule'å University of Technology in northern Sweden. Since April 2003, Carl-Henric Svanberg has been CEO of Swedish Ericsson. Every year the... view more... (2004-09-08)
