One objective of Sun's team of 70 researchers from six institutions is to probe jellyfish's life cycle and interactions with other organisms. Another aim is to pin down the cause of blooms; in Asia, chief suspects are overfishing, climate change, and eutrophication, or excess nutrients in coastal waters. Such knowledge may prove critical to thwarting an ecological hijacking.
China may have 2.8 trillion cubic meters of freshwater reserves, sixth in the world, but because of the country's population of 1.3 billion its per capita water availability is only one-fourth of the world average, according to the Ministry of Water Resources. This means China's water sources are limited and may not be able to support its fast economic growth over an extended period, says Pang Zhonghe.
Physicists at the Institute of Theoretical Physics, Chinese Academy of Sciences and the Department of Physics at Northeastern University have made a comparison of a number of competing dark energy models. The study is reported in Issue 9 of Science China Physics, Mechanics and Astronomy because of its significant research value.
In a paper in Physical Review Letters, Chao Li and co-workers at the Chinese Academy of Sciences, Beijing, and colleagues at Soochow University, China, and Hong Kong University of Science and Technology, experimentally demonstrate the first illusion-optics device.
Ouyang Ziyuan, an academician of Chinese Academy of Sciences and the chief scientist of the China's circumlunar exploration project, pointed out that the Chang'e III lunar probe can intelligently select a landing site on the moon. The probe can hover at a height of 4 meters above the lunar surface and turn off the engine to achieve a soft landing.
Tandem mass spectrometry can present numerous challenges to the analysis of biologically active substances, according to a team at the Chinese Academy of Sciences. Writing in BMC Bioinformatics, they explain that expanding protein databases and post-translational modifications have increased the demand placed on computing systems in recent years.
