Columbia engineers have developed a new approach, opposite to climate models, to correct inaccuracies using a high-resolution atmospheric model that more precisely resolves clouds and convection and parameterizes the feedback between convection and atmospheric circulation. The new simulation strategy paves the way for better understanding of the water and carbon cycles in the Amazon, enabling researchers to learn more about the role of deforestation and climate change on the forest.” (PNAS Online Early Edition 8/31)

Q&A: Researchers Explain a Strange High-Intensity Result at SLAC's X-Ray Laser

At extremely high intensities, X-rays stop behaving like the ones in your doctor’s office and begin interacting with matter in very different ways. This “nonlinear” X-ray behavior can only be seen at X-ray free-electron lasers. Recent experiments at the Department of Energy’s SLAC National Accelerator Laboratory have revealed a new, unexpected twist in that behavior that may be one for the textbooks and could change the way these powerful lasers probe matter.
