China-Germany Electric Automobile Seminar


A China-Germany seminar on electric automobiles, co-sponsored by Chinese Ministry of Science and Technology and German Federal Ministry of Transport, Building and Urban Development, was held on July 16, 2010 in Wuhan. More than a hundred representatives from government, universities, and industry of the two countries attended the meeting. Participants had an in-depth discussion of a range of issues concerning electric automobiles, including national plan, cost strategy, storage technology, safety technology, charging scheme, market preparedness, and introduction strategy. Participants agreed that the seminar makes a desirable platform for strengthening the cooperation and exchanges between government, industry, universities, and research institutes of the two countries, allowing a strategic alliance to be established in the area.


Electric automobile is a new area created under S&T cooperation between China and Germany, in a move to deepen cooperation and exchanges between the two countries. WAN Gang, Chinese Minister of Science and Technology reached an accord with German Federal Minister of Education and Research Dr. Annette Schavan in June 2009 to deepen the cooperation in the area of electric automobiles. WAN met with Dr. Peter Ramsauer, Federal Minister of Transport, Building and Urban Development in May 2010, and both sides agreed to jointly stage electric automobile demonstrations to support electric automobile demonstrations launched in China and Germany. In June 2010, WAN and Dr. Annette Schavan attended the opening ceremony of a China-Germany summit meeting on electric automobiles and an inauguration ceremony of a joint electric automobile research center. Both sides inked a joint statement to promote the collaborations in the area of electric automobile sciences, spurring up the R&D efforts in the area.  


More Support for China’s Scientific Continental Drilling


A team of Chinese scientists, led by Prof. WANG Chengshan at China University of Geosciences, has been working on the ties between major geological events appeared in the Cretaceous earth surface layers and climate change under a National 973 Program. With the support of the Daqing Oilfield, scientists launched a drilling project named Continental Cretaceous. The drilling has hit the depth over 2000m, and produced numerous findings. 


At a council meeting on international continental scientific drilling program, specialists from the National Science Foundation (US), GFZ German Research Centre for Geosciences, and Japan Ministry of Education, Culture, Sports, Science and Technology thought highly of the scientific continental drilling made in China, and confirmed their further support to the efforts. Up to date, China’s scientific continental drilling project has been supported by ICDP with a sum worth USD 1.2 million, mainly for studying the ties between the continuous continental deposit records under a high temperature over the Songliao Basin in the Cretaceous Period and greenhouse climate change. Chinese scientists will continue the study under international support.   





New Fossilized Bird Found




A study team, led by Prof. HU Dongyu at Shenyang Normal University, reported their findings on Shenshiornis primita, a first ever found new bird genus, in the recent issue of journal Acta Geologica Sinica. The fossilized bird, dated back to 120 million years, was found at an early Cretaceous stratum in Dapingfang Township, Chaoyang County in the west part of Liaoning. With a 40cm body length and a primitive non-linear head bone, Shenshiornis primita is a special bird genus appeared in the early stage of birds’ evolution. The bird has kept primitive cone shaped teeth, with a short tarsi bone for rear limbs, and a toe in reversed direction and three others in grasping position, implying its adaptation to tree resting.


Based on a comprehensive analysis of the bird, HU and coworkers believe that the movable head bone had a retarded development against the bird’s normal evolution. Meanwhile, the changed motion system has noticeably weakened the walking capability of the primitive birds. The finding presents the evidences for studying the evolution of birds’ movable head bone and their tree resting capability.   


Integrin Regulates Inflammatory Responses


Thanks to the support of Chinese National Natural Science Foundation and National 973 Program, CAO Xuetao, a Chinese Academy of Engineering academician, and coworkers found that integrin CD11b negatively regulates TLR-triggered inflammatory responses by activating Syk and promoting degradation of MyD88 and TRIF via Cbl-b. Further studies also show that that CD11b deficiency enhanced TLR-mediated responses in macrophages, rendering mice more susceptible to endotoxin shock and Escherichia coli–caused sepsis. CD11b was activated by TLR-triggered phosphatidylinositol 3-OH kinase and the effector RapL and fed back to inhibit TLR signaling by activating the tyrosine kinases Src and Syk. Syk interacted with and induced tyrosine phosphorylation of MyD88 and TRIF, which led to degradation of these adaptor molecules by the E3 ubiquitin ligase Cbl-b. Thus, TLR-triggered, active CD11b integrin engages in crosstalk with the MyD88 and TRIF pathways, and subsequently inhibits TLR signaling in innate immune responses. The finding was published in the recent issue of journal Nature-Immunology.


Novel Corn Species with Better Protein


Not long ago, FAN Xingming, a research fellow at Yunnan Academy of Agricultural Sciences, and coworkers worked out technical solutions for breeding new corn species with raised protein quality. They bred out Yunrui I, a corn species featured with high nutritional value and quality. The new variety is the only corn species that has been grown over an extensive area, with a strong resistance to gray leave diseases.


FAN and coworkers made a systematic study of the ties between the adaptability of tropical and temperate corns and the strength of hybrids, and produced Yunrui I featured with high and reliable yields, wide adaptability, and strong adversity resistance, using backcrossing techniques. A test made by Institute of Crop Germplasm Resources, part of the Chinese Academy of Agricultural Sciences, shows that the new species is strong in resistance to leave spot diseases, especially the gray leave diseases popular among the corn plants grown across Yunnan Province. Meanwhile, Yunrui I presents a fine food quality. Up to date, it has been grown over an area of 3.2343 million mu (1 mu= 0.0667 hectare) in Yunnan, Guangxi, and Guizhou, with a raised yield by 162 million kg, and a newly increased output worth RMB 629 million.   





Fast Neutron Reactor Became Critical


CEFR, a proprietary fast neutron reactor developed by China Institute of Atomic Energy, part of China National Nuclear Corporation, became critical on July 21, 2010. The development indicates that China National Nuclear Corporation has established a well functioned R&D and standard system for the sodium-cooled fast reactor, covering reactor physics, thermal techniques, dynamics, structure, looping, instrumental control, and electric part. Chinese scientists have produced a range of proprietary innovations, and more than a hundred patents. It is worth mentioning that the experimental reactor, made up of more than 200 sub-systems and over 7,000 pieces of equipment, has realized a localization as high as 70% or more.


Chinese scientists have also made some breakthroughs in engineering design. For example, they developed a passive residual heat removal system for accidents, the first of its kind in the world. Additionally, scientists have completed the design of a reactor refueling system.
