Underlying cause of massive pinyon pine die-off revealed
The high heat that accompanied the recent drought was the underlying cause of death for millions of pinyon pines throughout the Southwest, according to new research. view more (2005-10-11)
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)
Do green markets actually lead to improvements in environmental quality?
Goods and services with environmental benefits are a growing part of many sectors of the economy, and a timely new paper from the current issue of the Journal of Political Economy analyzes how our willingness to pay more for environmentally friendly products actually influences environmental quality and social welfare. view more (2006-09-13)
Is Britain flooding more than before?
Are river floods becoming more common? Are they bigger than they used to be? According to the results of a study to be published online today in Journal of Quaternary Science, researchers from the University of Wales in Aberystwyth demonstrate that Britain is now flooding more than in the past due to deforestation. Accurate instrumental records of... view more... (2003-02-25)
Bacteria Genome Research Could Save Orchards and Assist Blood Transfusions
Research led by the University Warwick into the genomes of two bacteria could save orchards from a previously almost incurable disease and also assist in treating complications arising from human blood transfusions. view more (2007-08-21)
Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their roots, stems and leaves or release into the air. view more (2007-10-16)
Biosphere 2 experiment shows how fast heat could kill drought-stressed trees
Widespread die-off of piñon pine across the southwestern United States during future droughts will occur at least five times faster if climate warms by 4 degrees Celsius, even if future droughts are no worse than droughts of the past century, scientists have discovered in experiments conducted at the University of Arizona's Biosphere 2. view more (2009-04-14)
Forests' long-term potential for carbon offsetting
As well as cutting our fossil fuel emissions, planting new forests, or managing existing forests or agricultural land more effectively can capitalise on nature's ability to act as a carbon sink. view more (2008-04-15)
Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. view more (2007-04-10)
Deep-rooted plants have much greater impact on climate than experts thought
Trees, particularly those with deep roots, contribute to the Earth's climate much more than scientists thought, according to a new study by biologists and climatologists from the University of California, Berkeley. view more (2006-01-12)
Tree rings show elevated tungsten coincides with Nevada leukemia cluster
Tungsten began increasing in trees in Fallon, Nev. several years before the town's rise in childhood leukemia cases, according to a new research report. view more (2007-05-01)
Multiple skin cancer risk behaviors are common among US adults
Whether you're basking on the beach during vacation, coasting down glittering white snow on a weekend ski trip, or simply walking the dog or running errands, sunlight's ultraviolet rays can damage your skin year-round. view more (2008-01-08)
The least sea ice in 800 years
New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now. The research results from the Niels Bohr Institute, among others, are published in the scientific journal, Climate Dynamics. view more (2009-07-01)
Storing carbon to combat global warming may cause other environmental problems, study suggests
Growing tree plantations to remove carbon dioxide from the atmosphere to mitigate global warming - so called "carbon sequestration" - could trigger environmental changes that outweigh some of the benefits, a multi-institutional team led by Duke University suggested in a new report. view more (2005-12-23)
Global warming greatest in past decade
Researchers confirm that surface temperatures in the Northern Hemisphere were warmer over the last 10 years than any time during the last 1300 years, and, if the climate scientists include the somewhat controversial data derived from tree-ring records, the warming is anomalous for at least 1700 years. view more (2008-09-02)
Causes of rubber tree bark necrosis identified
The rubber tree, Hevea brasiliensis, is cultivated in many humid tropical countries for the latex it produces, from which is extracted natural rubber mainly used by the tyre industry. Asia alone provides almost 95 % of the world production, where the first producer is Thailand whose rubber industry earns a regular income for 10 % of the... view more... (2005-04-15)
Space technology keeps Nuna II ahead of the pack
The Nuon Solar Team look set to beat their own world record for driving a sun-powered car across Australia in the World Solar Challenge. At the end of day 3 Nuna II, despite two flat tires, finished half an hour ahead of its closest competitors. Nuna II, raced by the Nuon Solar Team, and aided by ESA space technology, reached Cadney Homestead,... view more... (2003-10-21)
Tropical forest seed banks: a blast from the past
Seeds of some tree species in the Panamanian tropical forest can survive for more than 30 years before germinating. view more (2009-04-02)
Parasitic plants sniff out hosts
Parasitic plants do not haphazardly flail about looking for a host but sense volatile chemicals produced by other plants and identify potential hosts by their emissions. view more (2006-09-29)
American carnivores evolved to avoid each other, new study suggests
How do the many carnivorous animals of the Americas avoid competing for the same lunch, or becoming each other's meal? view more (2009-03-10)
