'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes. view more (2007-12-04)
Heavy metals accumulate more in some mushrooms than in others
A research team from the University of Castilla-La Mancha (UCLM) has analysed the presence of heavy metals in 12 species of mushroom collected from non-contaminated natural areas, and has found that the levels vary depending on the type of mushroom. view more (2009-11-02)
Nitrogen research shows how some plants invade, take over others
Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. view more (2009-07-07)
THE BIODIVERSITY OF FALLOW LAND:A FACTOR USEFUL FOR CONTROLLINGPLANT PARASITIC NEMATODES
Fallowing is a common practice for restoring soil fertility and structure in the tropics : it favours improvement in its physicochemical properties and the build-up of stores of organic matter, which are essential for the development of the telluric microfauna and microflora that inhabit soils. Researchers from the Laboratory of Biopedology of IRD... view more... (1999-09-13)
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)
Coastal bluffs provide more sand to California beaches than previously believed
Coastal geologists have assumed for years that sediment-laden rivers that enter the Pacific Ocean along the Central and Southern California coast supply up to 90 percent of the sand on the region's beaches. view more (2005-10-13)
Superscanner helps scientists see into the unknown
Researchers at The University of Nottingham have a new weapon in their arsenal of tools to push back the boundaries of science, engineering, veterinary medicine and archaeology. view more (2009-09-11)
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)
Beetle dung helps forests recover from fire
Armed with a pair of tweezers and a handful of beetle droppings, University of Alberta forestry graduate Tyler Cobb has discovered why the bug-sized dung is so important to areas ravaged by fire. view more (2007-12-04)
Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures. view more (2008-01-03)
U.S. Air Force Technology Helps Scientists Understand Plant Root Function
The McClellan Nuclear Radiation Center (MNRC) in Sacramento, CA was developed by the U.S. Air Force to detect corrosion and defects in aircraft structure using an imaging technique called neutron radiography. This technique is currently helping soil scientists understand the function of plant roots and their uptake of water and nutrients. view more (2008-09-09)
'Green Clean:' Researchers Determining Natural Ways To Clean Contaminated Soil
Researchers at North Carolina State University are working to demonstrate that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation - literally a "green" technology - plants and trees remove pollutants from the environment or render them harmless. view more (2009-09-18)
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)
A cushion of air trapped under the rice fields of Senegal
Rice cultivation uses great volumes of water, especially where the submerged-field method involving surge flooding irrigation is practised. Maintenance of a layer of water on the soil surface throughout the cropping period usually favours its infiltration deeper down. However, it has been known for many years that in some regions water often does... view more... (2004-04-15)
Urban Trees Enhance Water Infiltration
Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. view more (2008-11-20)
Anthrax bacterium's deadly secrets probed
New insights into why the bug that causes anthrax behaves in the unusual way that it does have come to light thanks to a development under the UK e-Science Programme. view more (2007-08-07)
Medications and cough syrups may cause cavities
A spoon full of sugar may help the medicine go down, but most dentists would likely encourage parents to skip that step when treating a child's illness. view more (2006-01-10)
Cryogenic Bank Of The Earth
The littoral plains of north-eastern Eurasia are covered with a thick layer of permafrost. This layer preserves seeds, spores and microorganisms. Some of them that are thousands and hundreds of thousands years old are still alive. The study of fossil life was supported by the Russian Foundation for Basic Research. Conditions of the glacial epoch... view more... (2003-11-06)
Entekhabi will lead science team for NASA satellite mission to map Earth's water cycle
MIT Professor Dara Entekhabi will lead the science team designing a NASA satellite mission to make global soil moisture and freeze/thaw measurements, data essential to the accuracy of weather forecasts and predictions of global carbon cycle and climate. view more (2008-04-29)
Shifts in soil bacterial populations linked to wetland restoration success
A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity. view more (2008-11-13)
