Chinas Three Gorges Dam, the largest dam project ever, has been seen by ecologists as an environmental disaster in the making. With construction scheduled to be completed later this year, little can be done to stop it, but some Chinese and American ecologists point out that the dark cloud of the environmental consequences does have a silver lining – an unprecedented opportunity to do environmental science.
In an article forthcoming in the May 23 issue of Science, Arizona State University landscape ecologist Jianguo Wu and co-authors Jianhui Huang, Xingguo Han, Zongqiang Xie and Xianming Gao, all from the Institute of Botany of the Chinese Academy of Sciences, argue that the project represents an opportunity to conduct arguably the largest and most complete experiment ever run on the effects of habitat fragmentation, an ecological condition that affects environments across the globe through the process of ongoing human development.
Habitat fragmentation occurs when human development or some other force eliminates large areas continuous natural habitat, leaving habitat "islands" where remaining species of plants and animals are left in a limited space, isolated from other similar communities and habitats. Examples of the condition are wild spaces (parks or undeveloped lots) that are surrounded by urban development, remnant patches of wilderness that are left when a forest is cleared for farming, or elevated terrestrial habitats that suddenly become scattered islands when a landscape is flooded. While some plant and animal species initially remain on the habitat fragments, the long-term stability of the isolated ecosystems is in question.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
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.

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...
