Improving China's acid rain control strategy
Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely... view more...

Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way. view more (2008-03-28)
Scrubbing sulfur
The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. view more (2009-08-18)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
Iraq war service: A risk factor for bronchiolitis?
A large group of soldiers returning from Iraq have been diagnosed with bronchiolitis, a disease affecting the small airways of the lung, according to Vanderbilt University Medical Center physicians who will present their findings at the American Thoracic Society's 2008 International Conference in Toronto on Wednesday, May 21. view more (2008-05-21)
Removal of Nitrogen from Motor Exhaust Sulfur-resistant process
Who doesn’t want to save fuel? Vehicles with lean-burning engines are therefore gaining ground. These engines work with excess air and can run on noticeably less fuel. This spares thewallet of the frequent driver, and also releases less carbon dioxide into the atmosphere. However,these exhaust gases are not a pure joy for the environment,... view more...

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen. view more (2006-08-24)
Unlike rubber bands, molecular bonds may not break faster when pulled
From balloons to rubber bands, things always break faster when stretched. view more (2009-06-18)
New approach removes sulfur from military-grade fuel; Syngas powers the process
The military needs to get the sulfur out of its fuel, in order to use the fuel to produce hydrogen for fuel cell use in the field. view more (2006-03-29)
1 sponge-like material, 3 different applications
A new sponge-like material that is black, brittle and freeze-dried (just like the ice cream astronauts eat) can pull off some pretty impressive feats. view more (2009-05-18)
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)
Clean fuels could reduce deaths from ship smokestacks by 40,000 annually
Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 - almost one-third higher than previously believed, according to the second major study on that topic. view more (2009-07-09)
Sudden collapse in ancient biodiversity: Was global warming the culprit?
Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today. view more (2009-06-19)
Better measurements reveal seasonal changes in sulfur
Researchers from the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have developed a new and improved technique for the simultaneous measurement of sulfur isotopic ratios and concentrations of atmospheric sulfate using snow samples from Greenland and Kyrgyzstan. view more (2005-10-10)
Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere
Scientists have discovered a bacterial "switch gene" in two groups of microscopic plankton common in the oceans. The gene helps determine whether certain marine plankton convert a sulfur compound to one that rises into the atmosphere, where it can affect the earth's temperature, or remain in the sea, where it can be used as a nutrient. view more (2006-10-30)
Commercial ships spew half as much particulate pollution as world's cars
Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study. Ship pollutants affect both the Earth's climate and the health of people living along coastlines. view more (2009-02-27)
Sulfur in marine archaeological shipwrecks -- the 'hull story' gives a sour aftertaste
Advanced chemical analyses reveal that, with the help of smart scavenging bacteria, sulfur and iron compounds accumulated in the timbers of the Swedish warship Vasa during her 333 years on the seabed of the Stockholm harbour. view more (2008-05-19)
Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

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)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
