Study suggests large methane reservoirs beneath Antarctic ice

SANTA CRUZ, CA -- The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas, according to a report by an international team of scientists in the August 2012 issue of Nature.


Team finds clue to polar ice shelf break-up

Results published by a team of polar scientists from Britain, Australia and France adds a new dimension to our understanding of Antarctic Peninsula climate change and the likely causes of the break-up of its ice shelves.


Scientists produce H2, a renewable energy source

Scientists at the University of Cambridge have produced hydrogen, H2, a renewable energy source, from water using an inexpensive catalyst under industrially relevant conditions (using pH neutral water, surrounded by atmospheric oxygen, O2, and at room temperature).


Drastic action needed to save marine species

LIVERMORE, Calif. -- Many marine species will be harmed or won't survive if the levels of carbon dioxide continue to increase. Current protection policies and management practices are unlikely to be enough to save them. Unconventional, non-passive methods to conserve marine ecosystems need to be considered if various marine species are to survive.


Progress on cheaper, more sustainable solar roof panel

PHILADELPHIA, Aug. 21, 2012 — With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists have described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity.


Evidence of link between extreme weather and global warming

PHILADELPHIA, Aug. 20, 2012 — New scientific analysis strengthens the view that record-breaking summer heat, crop-withering drought and other extreme weather events in recent years do result from human activity and global warming, Nobel Laureate Mario J. Molina, Ph.D., has warned.


Fueling the future with renewable gasoline and diesel

PHILADELPHIA, Aug. 20, 2012 — A new process for converting municipal waste, algae, corn stalks and similar material to gasoline, diesel and jet fuel is showing the same promise in larger plants as it did in laboratory-scale devices, the developers reported at the 244th National Meeting & Exposition of the American Chemical Society (ACS).


Extracting nuclear fuel from seawater

When you take a dip in the ocean, nuclear fuel is probably the farthest thing from your mind. Uranium floats in Earth's oceans in trace amounts of just 3 parts per billion, but it adds up. Combined, our oceans hold up to 4.5 billion tons of uranium – enough to potentially fuel the world's nuclear power plants for 6,500 years.
