Climate change is causing wildfires to burn more fiercely, pumping more greenhouse gases into the atmosphere than previously thought, according to a new study to be published in Nature Geosciences this week.

For years, geologists have argued about the processes that formed steep inner gorges in the broad glacial valleys of the Swiss Alps.
Researchers at Northwestern University have created a new infrared camera based on Type-II InAs/GaSb superlattices that produces much higher resolution images than previous infrared cameras.
"It is a bit like trying to move through a street crowded with an enormous number of people. If you move slowly enough you can make progress and the crowd and you 'flow'. However, if you try and sprint down the street you will just knock into so many people that you'll never be able to move at the speed you want to and hence everything becomes grid locked."
Polymeric porous framework of a bismuth citrate-based complex: A potential vehicle for drug delivery
YANG Nan, MAO ZongWan and SUN HongZhe et al., at the Department of Chemistry, University of Hong Kong and Sun Yat-sen University have characterized a series of bismuth citrate complexes by X-ray crystallography and modeled the structure of ranitidine bismuth citrate, a medicine used widely for the treatment of peptic ulcer and gastric reflux disease. The polymeric framework of bismuth citrate may serve as a "drug carrier" for delivery of other drugs in the human body. This significant contribution is reported in SCIENCE CHINA Chemistry 2010, 53(10).
Our research at the State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, has shown, based on a refined division and correlation of the graptolite-bearing strata in southern Jiangxi, China, that the Kwangsian Orogeny commenced in the early Katian Age of the Late Ordovician. Because of its significant research value, this study is published in Issue 11 of Science China Earth Sciences.
Doctors want patients asleep during surgery but anesthetic gases have a global warming potential as high as a refrigerant that is on its way to being banned in the EU - yet there is no obligation to report anesthetic gases along with other greenhouse gases such as CO2, refrigerants and laughing gas.
Agricultural – or Neolithic – economics replaced the Mesolithic social model of hunter-gathering in the Near East about 10,000 years ago. One of the most important socioeconomic changes in human history, this socioeconomic shift, known as the Neolithic transition, spread gradually across Europe until it slowed down when more northern latitudes were reached.
CANCUN/MEXICO, 2 December 2010—Not content to see farming remain outside the international climate change negotiations under way in Mexico, a broad coalition of 17 organizations will bring together more than 400 policy makers, farmers, scientists, business leaders and development specialists on Saturday, December 4 to define steps for opening the door to agriculture within the next six months, permitting its full inclusion in both national action plans as well as the global climate agenda.
CHAPEL HILL, N.C. -- There has been controversy about whether life originated in a hot or cold environment, and about whether enough time has elapsed for life to have evolved to its present complexity.
But new research at the University of North Carolina at Chapel Hill investigating the effect of temperature on extremely slow chemical reactions suggests that the time required for evolution on a warm earth is shorter than critics might expect.
The findings are published in the Dec. 1, 2010, online early edition of the Proceedings of the National Academy of Sciences.
Physicists at the Institute of Theoretical Physics, Chinese Academy of Sciences and the Department of Physics at Northeastern University have made a comparison of a number of competing dark energy models. They have tested and compared nine popular dark energy models using the latest observational data. The study is reported in Issue 9 (Volume 53) of SCIENCE CHINA Physics, Mechanics & Astronomy because of its significant research value.
The School of Nuclear Engineering and Technology at the East China Institute of Technology cooperated with the China Institute of Atomic Energy to investigate the high spin states of 84Sr. The study is reported in Issue 53 (October, 2010) of the Chinese Science Bulletin because of its significant research value.
Researchers from the College of Physical Sciences, GUCAS, have proposed to establish a new branch, unsteady aerothermodynamics, within the discipline of aerothermodynamics. The principal objectives of this new branch, to treat by theoretical means the study of physical phenomena relating to attached boundary layer flows, have been outlined in a preliminary investigation. A report based on a feasibility study has appeared in Vol. 54 No. 8 of Science China Physics, Mechanics & Astronomy.
