Warming land and ocean surfaces, melting glaciers, rising sea levels, and other recent evidence strongly suggest that Earths climate is already changing rapidly because of the buildup of greenhouse gases in the atmosphere, according to Warren Washington, senior scientist and head of the Climate Change Research Group at the National Center for Atmospheric Research (NCAR). Computer models of Earths climate support these observations, he says, and indicate more severe changes yet to come.
Even if societies successfully cap worldwide greenhouse gas emissions, the global climate will continue to warm into the 22nd century, though at a slower rate than if no attempt is made to control the emissions, Washington says. Policy makers must prepare to adapt to a changing climate even while slowing the greenhouse gas buildup, he says. Washington will present these conclusions in his talk, "Predicting the Climate of the 21st Century," at the annual meeting of the American Association for the Advancement of Science in Denver on February 16.
"Scientific confidence in the ability of models to project future climate has increased," says Washington. "Meanwhile, recent experiments and routine monitoring have found evidence of global climate changes already occurring that are much larger than can be explained by the climates natural variability." In his talk, Washington will explain how a computer model of global climate works and highlight what the most sophisticated models in the United States and elsewhere are now telling us about present and future climate.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.
They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
