At only about 1,000 in the wild, Chinas giant panda is among the most endangered species in the world. But there is still hope if we act fast. The pandas greatest threat is habitat loss and new research identifies high-quality habitat that, if protected, could increase the species chances of long-term survival.
"The current network of nature reserves provides protection for less than half of the pandas remaining habitat and fails to conserve essential habitat for dispersal," say Colby Loucks and Eric Dinerstein of the World Wildlife Fund-US in Washington DC, and four co-authors in the April issue of Conservation Biology. The giant pandas range has shrunk from the lowland forests of southeast China, northern Vietnam and northern Myanmar to six mountain ranges along Chinas Tibetan Plateau, where only 24 isolated populations survive today. Now, however, there is a window of opportunity to protect more of the pandas habitat, thanks to two conservation policies recently adopted by the Chinese government to help control flooding. First, under the National Forest Conservation Program, logging is banned in natural forests until 2010; and second, the Grain-to-Green policy is restoring forests on steep agricultural lands. These policies "have the potential to protect and restore panda habitat across the pandas entire range," say Loucks, Dinerstein and their colleagues.
Giant pandas need both high- and low-elevation forests as well as dispersal corridors. They need both types of forest because each supplies their primary food during part of the year: during the summer, pandas eat a kind of bamboo that grows at high elevations; and during the rest of the year, they eat another kind that grows at low elevations.

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...
