Delicate oxidation can transform greenhouse gas into useful chemicals
Studying wetlands as a producer of greenhouse gases
(Phys.org) —Wetlands are well known for their beneficial role in the environment. But UConn Honors student Emily McInerney '15 (CAHNR) is studying a less widely known role of wetlands – as a major producer ...
Ocean on Saturn moon could be as salty as the Dead Sea
(Phys.org) —Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea.
Hunt for extraterrestrial life gets massive methane boost
A powerful new model to detect life on planets outside of our solar system, more accurately than ever before, has been developed by UCL (University College London) researchers.
Large bacterial population colonized land 2.75 billion years ago
(Phys.org)—There is evidence that some microbial life had migrated from the Earth's oceans to land by 2.75 billion years ago, though many scientists believe such land-based life was limited because the ...
Researchers devise new, lower cost method to create more usable fuels
As the United States continues to lead the world in the production of natural gas, scientists from the Florida campus of The Scripps Research Institute (TSRI) have devised a new and more efficient method ...
Replacing coal and oil with natural gas will not help fight global warming
Both shale gas and conventional natural gas have a larger greenhouse gas footprint than do coal or oil, especially for the primary uses of residential and commercial heating.
SAR11, oceans' most abundant organism, has ability to create methane
The oxygen-rich surface waters of the world's major oceans are supersaturated with methane – a powerful greenhouse gas that is roughly 20 times more potent than carbon dioxide – yet little is known about the source of ...
Billion-year-old water could hold clues to life on Earth and Mars
A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.
America's natural gas system is leaky and in need of a fix, new study finds
The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, ...
Hybrid copper-gold nanoparticles convert CO2
Copper -- the stuff of pennies and tea kettles -- is also one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy. When fashioned into an electrode and stimulated ...
Large methane reservoirs suggested beneath Antarctic ice sheet
The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas, according to a report in the August 30 issue of Nature by an international team of scientists.
Cassini suggests icing on a Titan lake
(Phys.org)—It's not exactly icing on a cake, but it could be icing on a lake. A new paper by scientists on NASA's Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing ...
Thawing permafrost 50 million years ago led to extreme global warming events
In a new study reported in Nature, climate scientist Rob DeConto of the University of Massachusetts Amherst and colleagues elsewhere propose a simple new mechanism to explain the source of carbon that fed a ...
