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.

Friction stir welding is a still-young and thus often unfamiliar pressure welding process for joining flat components and semi-finished components made of light metals.
Scientists at the University of Stuttgart have now developed two new process variants that will considerably expand the areas of application for friction stir welding.
Technologie-Lizenz-Büro (TLB) GmbH supports the University of Stuttgart in patenting and marketing its innovations.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
