New American Chemical Society podcast The latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series describes the development of a new test that could help track down and prosecute terrorists. Amid concerns about the threat of terrorist attacks, scientists have been seeking better protection for the U.S. and other nations. One such team has developed a technique that could help authorities catch terrorists and put them...

2012-03-05 10:46:29

Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, found that untangling climate impacts from other factors can be difficult, even when scientists have access to decades of data on a forest's environmental conditions. Co-author Dr. Gene E. Likens of the Cary Institute comments, "Understanding how climate change is...

According to a new study, Arctic sea ice reductions may be intensifying the chemical release of bromine into the atmosphere, causing ground-level ozone depletion and the deposit of mercury in the Arctic. A team of scientists combined data from six NASA, European Space Agency and Canadian Space Agency satellites to develop a model of how air moves in the atmosphere to link Arctic sea ice changes to bromine explosions over the Beaufort Sea. "Shrinking summer sea ice has drawn much...

Recent cuts to the scientific workforce of Environment Canada, a government agency responsible for meteorological services and environmental research, threaten scientific research related to the ozone layer in the upper atmosphere and pollution in the lower atmosphere, according to environmental scientists in the U.S. These reductions in personnel and projected budget cuts also threaten existing international agreements. "Canada is a bellwether for environmental change, not only for Arctic...

In a breakthrough paper published in this week's issue of Science magazine, researchers from Sandia's Combustion Research Facility, the University of Manchester and Bristol University report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. (visit www.youtube.com/SandiaLabs to see a short video of Sandia combustion chemists discussing the research.) Criegee intermediates — carbonyl oxides — are implicated in...

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm. The findings, published in the journal Science Dec. 16, are based on historical changes in the chemical composition of bottom deposits in 36 lakes using an approach similar to aquatic archeology. More than three quarters of the...

Scientists are reporting development of a first-of-its-kind technology that could help law enforcement officials trace the residues from terrorist attacks involving nerve gas and other chemical agents back to the companies or other sources where the perpetrators obtained ingredients for the agent. A report on the technique, which could eventually help track down perpetrators of chemical attacks, appears in ACS' journal Analytical Chemistry. Carlos Fraga and colleagues explain that nerve...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Today's soil contamination is a direct result of man-made chemicals or other changes in nature's soil environment. This contamination most commonly occurs from underground storage tanks bursting, use of pesticides, discarding oil and fuel illegally, leakage of dirty surface water, draining of wastes from landfalls and knowingly dumping industrial wastes into the soil. The most widespread chemicals found are petroleum hydrocarbons, solvents, common pesticides, lead and additional heavy metals....

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
