An international team of scientists says it's figured out how to slow global warming in the short run and prevent millions of deaths from dirty air: Stop focusing so much on carbon dioxide.
Researchers from Sandia National Laboratories and UK partners have produced measurements of gas-phase Criegee intermediate reactions that they say will substantially existing knowledge of atmospheric chemistry. Criegee intermediates—carbonyl oxides—are pivotal atmospheric reactants whose reaction kinetics were only indirectly known.
More than a dozen studies have been conducted in an effort to track the molecular evolution of life by looking for evidence of that history in present-day protein structures. In one of the latest studies, researchers report they have identified an enzyme that was the first, or among the first, to generate molecular oxygen on Earth.
University of California, Davis, researchers have proposed a radical new way of thinking about the chemical reactions between water and metal oxides. The new paradigm could lead to a better understanding of corrosion and how toxic minerals leach from rocks and soil. It could also help in development of green technology.
When geochemist David Valentine and colleagues published a study in early 2011 documenting how bacteria blooms had consumed almost all of the deepwater methane plumes following the Deepwater Horizon oil spill in 2010, some people were skeptical. A recent publication explains how they did it.
Researchers from North Carolina State University and West Virginia University have developed a new technology that can reduce air pollutant emissions from some chicken and swine barns, and also reduce their energy use by recovering and possibly generating heat.
Work by scientists at the U.S. Department of Agriculture suggests that farmers in the Southeast could use the tropical legume sunn hemp ( Crotalaria juncea ) in their crop rotations by harvesting the fast-growing annual for biofuel.
New research suggests that China's impressive feat of cutting Beijing's pollution up to 50% for the 2008 Summer Olympics had some help from Mother Nature. Rain just at the beginning and wind during the Olympics likely contributed about half of the effort needed to clean up the skies, scientists found. The results also suggest emission controls need to be more widely implemented than in 2008 if pollution levels are to be reduced permanently.
Predictions of the loss of animal and plant diversity around the world are common under models of future climate change. But a new study shows that because these climate models don't account for species competition and movement, they could grossly underestimate future extinctions.
Through a combination of time-lapse live imaging and mathematical modeling of a special line of human breast cells, researchers have found evidence to suggest that for low dose levels of ionizing radiation, cancer risks may not be directly proportional to dose. This contradicts the standard model for predicting biological damage from ionizing radiation
Engineers at Brown University have developed a system that cleanly and efficiently removes trace heavy metals from water. In experiments, the researchers showed the system reduced cadmium, copper, and nickel concentrations, returning contaminated water to near or below federally acceptable standards.
A team of scientists from Oregon has collected microbes from ice within a lava tube in the Cascade Mountains. In environmental conditions that resemble those on Mars, the microbes tolerate temperatures near freezing and low levels of oxygen, and they can grow in the absence of organic food.
The following Websites are good sources of information related to the global R&D enterprise. Much of the information in the 2012 Global R&D Funding Forecast was derived from these sources, which are certainly not all-inclusive.
For the first time, the chemical 'fingerprints' of the element mercury have been used by University of Michigan researchers to directly link environmental pollution to a specific coal-burning power plant. This technique provides a tool that will enable researchers to identify specific sources of mercury pollution and determine how much of it is being deposited locally.
Federally funded research can be a solution to some of the nation's top challenges, say government laboratory executives.

50 years ago—and thousands of technologies ago—the R&D 100 Awards honored the first recipients.
According to a new analysis by a New York Botanical Garden scientist, there are probably at least 500 medically useful chemicals awaiting discovery in plant species whose chemical constituents have not yet been evaluated for their potential to cure or treat disease.
While it is possible to chemically scrub carbon dioxide from Earth's atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now. Best to focus on controls for coal-burning power plants, say researchers from Stanford University and the Massachusetts Institute of Technology.
A U.N. climate conference reached a hard-fought agreement Sunday on a complex and far-reaching program meant to set a new course for the global fight against climate change for the coming decades. The United States was a reluctant supporter, concerned about agreeing to join an international climate system that likely would find much opposition in the U.S. Congress.
As the Greenland Ice Sheet melts, the rockbound coast rises, as much at 15 mm or more per year. According to results from GPS stations around the island, the temperature spike in 2010 lifted the bedrock a detectably higher amount in a short five-month period.
The century-old mystery of a missing mineral in coral reefs has been solved by a team from The Australian National University. The team has uncovered a hidden stash of the mineral dolomite in coral reefs around the globe, ending a search that has lasted over 100 years.
