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)
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... 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... view more (2006-10-30)
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)
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)
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... view more (2000-08-16)
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)
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... view more (2008-05-21)
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)
Arctic expedition will investigate alien-like glacier
A scientific expedition to a remote glacier field in Canada's High Arctic may help researchers unlock the secrets about the beginning of life and provide insights for future exploration of our solar system. view more (2006-06-14)
Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
Iron 'snow' helps maintain Mercury's magnetic field, scientists say
New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground. view more (2008-05-08)
Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues. view more (2006-04-12)
Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere. view more (2008-01-17)
Fuel cells help make noisy, hot generators a thing of the past
Two core technologies developed at the Department of Energy's Pacific Northwest National Laboratory - a fuel desulfurization system and a fuel reforming system - were instrumental in the demonstration of an electric power system operating on JP-8, a fuel commonly used in military operations. view more (2007-12-12)
UGA scientists discover bacterial 'switch gene' that regulates oceans' sulfur emissions into the air
The number of plankton in the seas is almost beyond comprehension. A single teaspoonful of ocean water holds several million of these microscopic drifters, and in recent years, scientists have discovered plankton are involved with everything from the health of the water to global warming. view more (2006-10-27)
Unusual carbohydrate structure in the cell walls of tuberculosis bacteria-a new point of attack for drugs?
Even though we have lost much of our fear of tuberculosis in the industrialized countries, according to the WHO about 2 mio. people worldwide die each year of this infectious disease. Researchers at the University of Leeds have now discovered a carbohydrate with an unusual structure in the cell... view more (2004-07-27)
Dried distiller's grains can help produce more beef
Supplemental feeding of dried distiller's grains to cattle can help produce more beef in grazing programs, a Texas Agricultural Experiment Station researcher said. view more (2007-01-05)

Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate. view more (2008-09-10)
Water detection at Gusev crater described
A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit. view more (2005-09-08)
Researchers probe a DNA repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA. Enzymes called helicases play a key role in human health, according to Maria Spies, a University of Illinois biochemistry professor. view more (2008-02-19)
New catalysts may create more, cheaper hydrogen
A new class of catalysts created at the U.S. Department of Energy's Argonne National Laboratory may help scientists and engineers overcome some of the hurdles that have inhibited the production of hydrogen for use in fuel cells. view more (2007-08-22)
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... view more (2007-09-10)
Chandra examines Jupiter during new horizons approach
On February 28, 2007, NASA's New Horizons spacecraft made its closest approach to Jupiter on its ultimate journey to Pluto. This flyby gave scientists a unique opportunity to study Jupiter using the package of instruments available on New Horizons, while coordinating observations from both space-... view more (2007-03-02)
