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.

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
