Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2008-07-23)
Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists. view more (2007-09-10)
Satellite sniffs out chemical traces of atmospheric pollution
The recent Hague talks on global warming focused attention on the so-called greenhouse gases in our atmosphere. But these gases are only a part of the story. Mankind generates a wide variety of emissions that are changing the chemistry and composition of our planet~s atmosphere. Satellite monitoring is helping scientists to understand those... view more... (2000-12-15)
Researchers successfully simulate photosynthesis and design a better leaf
University of Illinois researchers have built a better plant, one that produces more leaves and fruit without needing extra fertilizer. The researchers accomplished the feat using a computer model that mimics the process of evolution. Theirs is the first model to simulate every step of the photosynthetic process. view more (2007-11-12)
Lack of sleep activates body's defence mechanisms
A lack of sleep is considered a threat situation, which activates the body's defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations. view more (2005-03-16)
Air monitoring helps anticipate possible ecosystem changes
When rain settles the atmosphere and brings air pollutants to the ground, it can have a lasting effect on ecosystems, sometimes hundreds of miles away, according to a Texas AgriLife Research agricultural engineer. view more (2008-06-26)
Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth. view more (2008-06-03)
Simulating kernel production influences maize model accuracy
Recently, researchers at Iowa State University discovered a way to increase the accuracy of a popular crop model. By zeroing in on early stages leading up to kernel formation, scientists believe they can help improve yield predictions across a variety of environmental conditions. view more (2007-09-24)
Nitrous gases and zinc in the crosshairs
The Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area established by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has issued the MAK and BAT Values List for 2009. This year's list contains 62 changes and new entries. view more (2009-07-29)
Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to occur. view more (2005-08-09)
New mechanism for nutrient uptake discovered
Biologists at the Carnegie Institution's Department of Plant Biology have discovered a new way that plant cells govern nutrient regulation—neighboring pore-like structures at the cell's surface physically interact to control the uptake of a vital nutrient, nitrogen. view more (2007-02-12)
New nanostructured thin film shows promise for efficient solar energy conversion
In the race to make solar cells cheaper and more efficient, many researchers and start-up companies are betting on new designs that exploit nanostructures--materials engineered on the scale of a billionth of a meter. view more (2008-01-09)
Urine collected and purified separately
From an environmental and cost perspective, it is a good idea to collect and purify urine separately, rather than simply allowing it to flow into the sewer view more (2006-06-23)
First Cryopreservation Seed Bank For Arabica Coffee
The storage of coffee (Coffea arabica) seeds to ensure preservation of their genetic resources is an important problem. Like many other tropical plants, coffee seeds cannot be conserved in cold storage because they remain cold-sensitive. IRD (Institut de recherche pour le développement), with the financial backing of the BRG (Bureau des... view more... (2000-09-14)
Primitive Visitor From Space Arrives In UK
Scientists from the Natural History Museum (NHM) in London, working with colleagues from the Open University (OU) in Milton Keynes, have been examining an intriguing arrival from outer space. The Tagish Lake meteorite, which fell in the Yukon region of northern Canada on the morning of 18 January 2000, contains some of the most primitive material... view more... (2001-03-31)
Researchers identify energy gains and environmental impacts of corn ethanol and soybean biodiesel
The first comprehensive analysis of the full life cycles of soybean biodiesel and corn grain ethanol shows that biodiesel has much less of an impact on the environment and a much higher net energy benefit than corn ethanol, but that neither can do much to meet U.S. energy demand. view more (2006-07-12)
New study confirms the ecological virtues of organic farming
Organic farming has long been touted as an environmentally friendly alternative to conventional agriculture. view more (2006-03-07)
Ecosystem of vanishing lake yields valuable bacterium
In the salt flats near a slowly vanishing lake, a team of researchers have found never-before-seen bacterium that could clean up some of humanity's pollution. view more (2006-10-18)
Are tougher electronic components on the way?
Like modern day alchemists, materials scientists often turn unassuming substances into desirable ones. But instead of working metal into gold, they create strange new compounds that could make the electronic components of the future smaller, faster, and more durable. view more (2006-03-09)
Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. view more (2009-01-14)
