Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study.
As a result, more of the greenhouse gas will be left to concentrate in the atmosphere.
Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture. The research team is publishing these findings in Science on the 8. January.
An international research project involving the University of Adelaide has revealed that the magnetic field in the centre of the Milky Way is at least 10 times stronger than the rest of the Galaxy.
The evidence is significant because it gives astronomers a lower limit on the magnetic field, an important factor in calculating a whole range of astronomical data.
Researchers from the Max-Planck-Institute for Nuclear Physics, the University of Adelaide, Monash University and the United States have published their findings in Nature this week.
AMES, Iowa – Three Iowa State University physicists who took winter trips to the Large Hadron Collider for meetings and experimental work are starting to see real data from the planet's biggest science experiment.
Finally.
The multibillion-dollar collider made international news on Sept. 10, 2008, when it sent its first beam of protons around 17 miles of underground tunnel near Geneva, Switzerland. But breakdowns in the machine's high-current electrical connections forced a complete shutdown for more than a year of repairs and tests.
Researchers of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that has not been directly observable so far: the Zitterbewegung. They have published their findings in the current issue of the journal Nature.
ST. LOUIS -- Recent recommendations by the Institute of Medicine (IOM) call for women who are overweight or obese to gain more weight than they should, a Saint Louis University obstetrician wrote in a January commentary for Obstetrics & Gynecology.
Why do we chew our food? Research has shown that it is not, as has long been presumed, to make chunks of food small enough to swallow without choking. Biomechanics, who have modelled the cohesive strength of food after a certain amount of chewing, have shown that we actually chew our food to ensure it is in a firm blob and, therefore, safe to swallow.
Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources. A study this week in the Proceedings of the National Academy of Sciences outlines formations on land as well as offshore, where scientists from Columbia University's Lamont-Doherty Earth Observatory say the best potential sites may lie.
There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future.
Scientists documented evidence that the Arctic Ocean and Nordic Seas were too warm to support summer sea ice during the mid-Pliocene warm period (3.3 to 3 million years ago). This period is characterized by warm temperatures similar to those projected for the end of this century, and is used as an analog to understand future conditions.

Transforming lead into gold is an impossible feat, but a similar type of "alchemy" is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. According to the team's leader A.
The faint tug of the sun and moon on the San Andreas Fault stimulates tremors deep underground, suggesting that the rock 15 miles below is lubricated with highly pressurized water that allows the rock to slip with little effort, according to a new study by University of California, Berkeley, seismologists.
New Rochelle, NY, December 22, 2009—Global warming, pollution, and the environmental consequences of energy production impose a greater burden on low-income, disadvantaged communities, and strategies to prevent these inequities are urgently needed. A provocative collection of articles on climate justice presents the global implications of climate change and its effects on human health and the environment in a special issue of Environmental Justice, a peer-reviewed journal published by Mary Ann Liebert, Inc.
ANN ARBOR, Mich.---Using a technique that provides detailed images of nanoscale structures, researchers at the University of Michigan and Detroit's Henry Ford Hospital have discovered changes in the collagen component of bone that directly relate to bone health.
Their findings, published online Dec. 16 in the journal Bone, could lead to new methods of diagnosing osteoporosis and other diseases affecting collagen-containing tissues.
