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)

Loss of just one species makes big difference in freshwater ecosystem, study finds
Researchers at Dartmouth, Cornell University, and the University of Wyoming have learned that the removal of just one important species in a freshwater ecosystem can seriously disrupt how that environment functions. This finding contradicts earlier notions that other species can jump in and... view more (2006-08-21)

Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge... view more (2005-08-19)

New laser research could improve oil exploration success
CSIRO Petroleum and German-based research centre Laser Zentrum Hannover eV (LZH) are collaborating in a project that could save millions of dollars in oil exploration and introduce new Australian geochemical and petroleum analysis techniques to Europe.   view more (2005-02-06)

Nutrient-poor oceans generate their food "hot spots"
The oceans have their desert zones, in other words areas poor in nutrients and unfavourable for phytoplankton to develop. Half of the southern Pacific thus consists of great expanses of warm water with an average temperature of 28 °C (a greater surface area than Europe), which receives no input... view more (2004-01-13)

Scientists design a tool for detection of rogue molecules “on the run”
A research group of the Microtechnology Centre at Chalmers, MC2, at Chalmers University of Technology in Göteborg, Sweden, has developed an ultra-sensitive device for detecting the presence of organic molecules present in space. Organic material as far away from us as many thousands of light... view more (2002-04-16)

Most widely used organic pesticide requires help to kill
The world's most widely used organic insecticide, a plucky bacterium known as Bacillus thuringiensis or Bt for short, requires the assistance of other microbes to perform its insect-slaying work, a new study has found.   view more (2006-09-26)

Deep biosphere research points to new methods for recovering petroleum
Miles below us, deep within Earth's crust, life is astir. Organisms there are not the large creatures typically envisioned when thinking of life.   view more (2008-10-08)

Hybrid advanced materials and the effect of Zirconium on synthesis and properties
Organic-inorganic hybrid materials are significantly important materials due to their peculiar properties. These properties come from a unique combination of the properties of the base components.   view more (2007-05-30)

Many weather factors needed for accurate climate change predictions
Current climate change impact models that consider only one weather variable, such as increasing temperature, sometimes spawn unsubstantiated doomsday predictions, according to researchers at Purdue and North Carolina universities.   view more (2006-11-07)

Scientists behind 'doomsday seed vault' ready the world's crops for climate change
As climate change is credited as one of the main drivers behind soaring food prices, the Global Crop Diversity Trust is undertaking a major effort to search crop collections-from Azerbaijan to Nigeria-for the traits that could arm agriculture against the impact of future changes.   view more (2008-09-18)

UCLA chemists design world's lowest-density crystals for use in clean energy
Chemists at UCLA have designed new organic structures for the storage of voluminous amounts of gases for use in alternative energy technologies.   view more (2007-04-13)

Commercial aquatic plants offer cost-effective method for treating wastewater
Nursery and greenhouse operations depend on the use of fertilizers, growth regulators, insecticides, and fungicides. Growers also rely on the use of soilless media, or substrate, in the production of container crops.   view more (2008-09-30)

Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East... view more (2001-09-07)

Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.   view more (2007-10-30)

Some biofuels might do more harm than good to the environment, study finds
Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions.   view more (2008-05-28)

A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics".   view more (2008-07-01)

When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure.   view more (2008-10-17)

Nanomaterials vulnerable to dispersal in natural environment
Laboratory experiments with a type of nanomaterial that has great promise for industrial use show significant potential for dispersal in aquatic environments - especially when natural organic materials are present.   view more (2006-12-19)

Commission's Joint Research Centre forecasts this year's crop losses caused by drought
The Commission's Joint Research Centre (JRC) uses its advanced crop yield forecasting system to predict the effects of the persisting drought on this year's harvest in the European Union. The expected drop in the main crop yields ranges from about 2% for potato to 25% for sunflower at EU level. The... view more (2003-08-20)

Toward plastic spin transistors
University of Utah physicists successfully controlled an electrical current using the "spin" within electrons - a step toward building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics.   view more (2008-08-18)

Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures.   view more (2007-03-12)

Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with... view more (2001-03-27)

Do higher corn prices mean less adherence to ecological principles?
Expectations of higher corn prices are leading some farmers to neglect or ignore integrated pest management strategies, and their behavior could undermine the very technologies that sustain them, University of Illinois researchers report today at the American Chemical Society meeting in Boston.   view more (2007-08-22)

Sensor of plastic can be produced in a printing press
Electrochemical transistors made of plastic open myriad possibilities. Since both electrons and ions are active, they can function as a bridge between traditional electronics and biological systems. A new dissertation from Linköping University in Sweden describes a simple and inexpensive... view more (2005-02-08)
