Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Climate change poses a huge threat to human health
Climate change will have a huge impact on human health and bold environmental policy decisions are needed now to protect the world's population, according to the author of an article published in the BMJ today. view more (2008-01-25)
Raindrops go ballistic in research on soil erosion
Raindrops can wreak havoc on Earth. They just do it on a microscopic scale. At that scale, raindrops hitting bare ground have nearly the force of a hammer hitting a mound of dirt. view more (2007-01-19)
Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. view more (2005-12-20)
Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder. view more (2006-06-21)
New lunar meteorite found in Antarctica
Although last year's inclement weather resulted in fewer Antarctic meteorite recoveries than usual, scientists have recently discovered that one of the specimens is a rare breed - a type of lunar meteorite seen only once before. view more (2006-09-15)
Scientists find safer ways to detect uranium minerals
The threat of 'dirty' bombs and plans to use nuclear power as an energy source have driven Queensland University of Technology scientists to discover a new, safer way of detecting radioative contamination in the ground. view more (2006-11-22)
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)
"Acid rain" and forest mass: another perspective
A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined. view more (2005-10-14)
No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today. view more (2005-12-02)
Microbes convert 'Styrofoam‚—˘' into biodegradable plastic
Bacteria could help transform a key component of disposable cups, plates and utensils into a useful eco-friendly plastic, significantly reducing the environmental impact of this ubiquitous, but difficult-to-recycle waste stream. view more (2006-02-24)
Dust storms may carry bacteria to Japan from China
Bacteria found in soil around Tokyo are not indigenous to the area. A study published in the open access journal Saline Systems reveals a large proportion of salt-loving bacteria in non-saline soil around Tokyo. The researchers suggest that dust storms may have carried the bacteria from their natural habitats in China. view more (2005-10-20)
Ammonia-loving archaea win landslide majority
A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth's most abundant land-based creatures that oxidize ammonia. view more (2006-08-17)
Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming. view more (2005-10-13)
Water detection at Gusev crater described
A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit. view more (2005-09-08)
Water, air and soil pollution causes 40 percent of deaths worldwide, Cornell research survey finds
About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. view more (2007-08-14)
How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in. view more (2007-03-12)
Plastic surgeons countdown first full facial transplantation
Even after news of the first partial facial transplantation performed in France spread around the world, plastic surgeons have continued to research how to make the first full facial transplantation a reality. view more (2006-03-02)
Peat and forests save permafrost from melting
Permafrost may be buffered against the impacts of climate change by peat and vegetation present in the northern regions, according to a study by McMaster researchers. view more (2007-09-14)
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)
