Northeastern environmental scientist finding could improve global warming forecast models
A Northeastern University researcher today announced that he has found that the soil below oak trees exposed to elevated levels of carbon dioxide had significantly higher carbon levels than those exposed to ambient carbon levels. The findings are consistent with the hypothesis that elevated carbon dioxide levels are increasing carbon storage in terrestrial ecosystems and slowing the build-up of carbon dioxide levels in the atmosphere. Carbon dioxide is thought to cause global warming by trapping heat radiated by the Earth.
The research, published in the latest on-line edition of the journal Earth Interactions, represents an important advance in the global warming research. The lead author on the article, “Soil C Accumulation in a White Oak CO2-Enrichment Experiment via Enhanced Root Production,” is Kevin G. Harrison from the department of earth and environmental sciences at Northeastern. Contributors also include Richard J. Norby and Wilfred M. Post from the Oak Ridge National Library in Tennessee and Emily L. Chapp form the University of Hawaii.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
