President Zemin JIANG met with Professor Neal Lane, the former Assistant to the US President for S&T (Director of White House Office of S&T Policy) in Zhongnanhai on Nov. 26, 2001
During his visit to the Wuhan Institute of Aquatic Biology (IAB) on 26 October, CAS President Yongxiang LU pointed out, “To become a world-famous institute of limnology, the IAB must try to address the ecological and productive issues of rivers and lakes in China, establish world-recognized representative schools of thought, and achieve research outcomes that can not be evaded in the history of science written by foreign (other than Chinese) scholars. That has to be based on an efficient mechanism. The key is to vitalize scientific thinking and form good academic atmosphere by encouraging communication and collision of ideas. It is important to hold regular international workshops, host first-rate visiting scientists from abroad, bring up outstanding disciplinary pioneers who publish high-quality papers on well-known magazines and serve as editors or editor-in-chiefs for such magazines, and establish a sound system of assessment. ”
LU added that the IAB should expand its contacts and cooperation with society, and that it should not confine its vision to a small region like Hubei Province, but should embrace the whole country and the whole world. Some results of the Institute’s research can be introduced to Southeast Asia through programs that provide aids to foreign countries.
At 9:00am, 12 October 2001, a press conference on the completion of Indica rice (Oryza Sativa Subsp. Shien) genome work draft was held by the Chinese Academy of Sciences (CAS) in collaboration with the State Development Planning Commission and the Ministry of Science and Technology. Yiyu CHEN, Vice President of CAS, announced that the Center of Genome & Bio-informatics, CAS, as well as, Beijing Huada Center of Gene Research, had accomplished the work draft and database of Chinese Indica rice genome, that the achievement was at the international leading level, and that the data would be released and free accessible to all. That is, indeed, an important contribution of Chinese scientists to mankind, and a major scientific achievement in the field of life sciences that has reached the world’s leading level and in which the Chinese nation should take pride.Major partners of the project included the Institute of Genetics, CAS and the National Center for Hybrid Rice Research. Besides, the CAS Institutes of Computing Technology, Theoretical Physics, and Biophysics, Peking University, Zhejiang University, and Digital China Corporation had also been involved in the work. Acknowledgement also goes to domestic and international peers, distinguished scientists and rice breeders who had shown their great concern and provided their kind support.
The work draft of Chinese rice genome is based on the "9311" Indica Rice, a super-hybrid rice species bred by Longping YUAN, Member of CAS.
to the results of assembly and data analysis, the work draft and
database of Chinese rice genomes are at the advanced world level in the
Both the percentages of genome sequencing coverage and gene coverage are
beyond 95%, including all the 12 chromosomes of rice genome. The
accuracy of 90% of the areas arrives at 99%, fully meeting the
requirements of the work draft.
A mathematical model for repeat sequence processing with a unique
algorithm has been developed to overcome the difficulty of assembling by
means of “case shot” whole genome sequencing. It has dispelled the
obstacle of theoretical computation to taking the advantage of
large-sized computers in processing mass data. In comparison with
foreign work of the same kind, the new technical system reduces the
amount of calculation by close to 80%.

On 29 October, the Shanghai Centre for Human Genome Research announced that Chinese scientists had finished the precise sequencing of the whole genomes of three important human and plant pathogens, i.e., Leptospira, Staphylococcus epidermidis and Xanthomonas campestris.
Microbial Genome Programme (MGP) is another great project in the field of life sciences succeeding the Human Genome Programme (HGP). It is closely related to human life. For examples, the infection of Staphylococcus epidermidis ranks top among the four infectious diseases found in hospitals; Leptospirosis is one of the main epidemic infections when pestilence comes after calamity and Xanthomonas campestris can lead to worldwide black rot of all crucifers and cause drop in production.
In addition to the whole-genome sequencing of the above three pathogenic microbes, Chinese scientists also identified a whole set of genes for maintaining their vital activity, discovered a series of functional genes associated with pathogenicity and assessed a number of prospective target genes for developing a new generation of bacterins. Research on functional genes regarding the three pathogens has reportedly been carried out on a large scale.According to sources, the whole-genome sequencing information of the three pathogenic microbes will be released to the international public database and accessible to all, initiating the principle of scientific ethics: “genomic results should bring benefit to mankind”.
The National Observatory has decided to name five planetoids discovered in recent years after the names of five Chinese scientists: Ganchang WANG, Fangyun CHEN, Jiachi YANG, Wenjun WU and Yisheng MAO. A naming ceremony will be held in a few days’ time.
According to the Observatory, the five planets were discovered successively in recent years within the solar system by the institution. In view of the eminent contributions of the five scientists in their respective domains, the Observatory submitted a proposal to the IAU Nomination Committee for Small Celestial Bodies that the planets be named after the scientists, which was recently approved. The naming of planetoids after our scientists is a special honor to China. Only a few Chinese scientists like Tsenning YANG, C. Samuel LEE and Jingrun CHEN have had the honor before.In a recent issue of the Bulletin of planetoids, the IAU Nomination Committee for Small Celestial Bodies briefed the reasons for the naming: Academician Ganchang WANG is a leading scientist in the fields of nuclear physics, cosmic rays and fundamental particles in China, who has played a key role in the country’s development of A-bombs and H-bombs; Academician Fangyun CHEN has made unique contributions to radio electronics and satellite test control technology; Academician Jiachi YANG, as a preeminent expert in automatic control and space technology, has made outstanding contributions to the development of satellite technology in China; Yisheng MAO, founder of modern bridgework in China, designed China’s first bridge with modern structure, the Qiantangjiang Bridge; and Academician Wenjun WU is a distinguished mathematician in topology and the mechanization of mathematics, who invented the “Wu’s Method” that is applied extensively by international peers. They well deserve the honor.

Importance Attached to Polar High Altitude Atmospheric Physical Study
According to Dengyi GAO, a researcher at the Institute of Atmospheric Physics, CAS, the Polar Regions are perfect places for studying the altitude atmospheric physical process, and enhancing investigation on the regions is of significant importance to China’s aviation industry and stellar exploration.
The North Pole Scientific Expedition, organized by the China Association for Scientific Expeditions and headed by Prof. GAO, landed on Tromso，a city in the North of Norway on 17 October 2001. The expedition planned to fly to Svalbard(Norway) on 19 October to establish China’s first North Pole station for scientific exploration there, and then begin their three-year multi-disciplinary integrated survey on the North Polar Region. It will be China’s longest scientific march into the North Pole.
GAO is the first Chinese scholar who has conducted surveys on all the “three poles” of the earth (the South Pole, the North Pole and the Qinghai-Tibetan Plateau). He introduced that the subject of high altitude atmospheric physics is the geophysical phenomena and physical processes that take place in the area between 30km high above the earth surface and the interplanetary space. It is thus a frontier discipline between astrophysics and geophysics, to study the altitude atmospheric structure, ionosphere and Earth-Sun space physics.
He said that the North Pole is a crucial and sensitive area having impacts on the global climate, in particular on China’s climate and environmental changes. Chinese scientists wish to strengthen collaborative research in multiple areas with the Norwegian Institute of Polar Environment (NIPE).
Dengyi GAO said, NIPE is advanced in the glaciological and biological study of the North Pole. In addition to academic exchange, Chinese scientists plan to carry out collaborative projects on polar climate and environment with NIPE. Cooperative agreements between the two sides will be signed within the next two years.

Perennial Drought: the Main Cause of Qinghai Lake’s Drawdown
Haizhou MA, professor at the Qinghai Institute of Salt Lakes, CAS, discovered that human activities produce no significant effects on the drawdown of the Qinghai Lake; it is perennial drought and warm that have caused the drop in the water level.Research shows that the drawdown of the Qinghai Lake is mainly resulted from the perennially dry and warm climate, which causes the depletion of water due to excessive evaporation from the surface of the Lake in comparison with the supply of water to it. The water supply to the Lake is composed of surface runoff, underground runoff and precipitation, while the consumption of water from the Lake comprises surface evaporation, human consumption and phreatic water evaporation. Calculations show that the annual average supply of water to the Lake is 3.793 billion cubic meters, while the annual average consumption of water from the Lake is 4.138 billion cubic meters, the balance being 435 million cubic meters. According to a survey, human activities account for only 1-2% of the total consumption of lake water, indicating that human consumption of water does not make significant contributions to the change of the lake water as a whole.
China-ESA Cooperative Agreement on Twin-Satellite Programme Signed
On 9 July 2001, a Chinese delegation comprising the National Space Administration (NSA) and the Chinese Academy of Sciences signed a cooperative agreement on the Twin-Satellite Exploration Programme of China’s Geo-Space Environment with the European Space Agency (ESA). According to the agreement, the two satellites of the Programme, after they are launched in 2003, will join the four geomagnetosphere detecting satellites of the Cluster Plan launched by ESA in 2000 to form a 6-point solid detector system of the geomagnetospheric space for the first time in human history.
In 1983, ESA initiated a Cluster Plan consisting of four identical satellites. In 1997, a group of scientists headed by Academician Zhenxing LIU from the Center for Space Sciences and Applied Research (CSSAR), CAS, put forward the proposal of implementing large-scale synchronous detection of the magnetospheric space by using two satellites whose orbits intersect each other, namely, the Twin-Satellite Programme. The proposal immediately attracted the attention of participant scientists of the Cluster Plan, who clearly expressed their wishes to take part in China's Twin-Satellite Programme. After several negotiations, it was finally agreed that ESA would provide 10 scientific detectors, including 6 detectors to be carried on the equatorial satellite and 4 on the polar satellite. The participation of ESA has enabled the shared processing of the observation data obtained by the Twin-Satellite Programme and that by the Cluster Plan.
The platform for the two satellites of the Twin-Satellite Programme will be developed by the Institute of Space Technology of China.
Founding Ceremony of CAS-MPG Partner Group on Geometric Analysis Held in Beijing

Metaphase Somatic Cell-Cloned Calf Successfully Developed
ZHOU, a biologist at the Chinese Academy of Sciences, in collaboration
with scientists from the French National Institute of Agronomy,
successfully developed the world’s first metaphase somatic cell-cloned
calf by using the improved cell cycle synchronizing method and the
“trauma resection” technique. The 3-month-old cloned calf is healthy
and lively. All of its physical and chemical indexes are normal.
When the calf was born, it happened that China had just won the bid for the 2008 Olympic Games. The French scientists decided to name the calf Olympics-2008. According to scientists, before Olympics-2008 was born, all somatic cell-cloned calves were produced by using resting or trophophase cells. (Its cell cycle was asynchronous with that of the ovum.) It has been known that, the synchronization of cell cycles can raise the efficiency of cloning, and it is an important means for researching into the relationship between nucleus and cytoplasm. To solve the problem, Chinese and French scientists conducted in-depth study on cell cycles, and, by combining the “trauma resection” technique invented by Dr. Qi ZHOU, developed the first metaphase somatic cell-cloned calf. Researchers say that the technology will greatly improve the efficiency of animal cloning, which is very important to promoting the research on cloning technology.
Sino-Japanese Joint Integrated Field Pre-survey of the Heihe River Basin Finished
The Sino-Japanese Joint Integrated Field Pre-survey of the Changes in Man-and-Nature Relations of the Heihe River Basin has recently been finished.Heihe is the second largest inland river basin in the northwest of China, covering an area of 140,000 km2. In May 2001, Academician Guodong CHENG, Director of the Cold and Arid Regions Environmental and Engineering Institute of CAS, signed with Prof. Hidaka Toshitaka, Director of the Institute of Man and Nature, Ministry of Educational, Cultural, Sports, Science and Technology (Japan), on a memorendum of academic exchange and collaborative research in the field of man-and-nature relations between the two sides. According to the memorendum, the two parties established a joint expedition of 16 experts to conduct half-a-month survey in China beginning from the early September 2001.
The expedition made a multi-disciplinary integrated survey on the "July 1" Glacier, the Jiuquan Farm Oasis in Zhangye, the natural ecosystem in Ejina Banner, the relics of Heichengzi and many other historic sites. After the preliminary integrated survey, the two sides reached common understanding on the study of ice cores, the relations between climate and glaciers, regional water cycle and hydrochemical movement, the interactions between the ecosystem and hydrological process, water for social-economic development, natural isotopes of water, and so on, and initialed an agreement on academic exchange and collaborative research.
Young Talented People Heavily Burdened
following major actions of reform taken by the Institute of Modern Physics,
Chinese Academy of Sciences have pushed the young talented people of the
Institute to the forefront of innovation with heavy burdens:
Establishing project groups that are put under the direct management of the
Institute as a substitute for former research laboratories, thus putting an
end to the history of research projects under the dual administration of
both the Institute and corresponding laboratories in the past decades. The
advantage of cutting out the intermediate link of laboratories is to bring
closer the relationship between the institute and groups and thus improve
the efficiency of management.
2. Readjusting the laboratories of the Accelerator System to the needs of the ongoing mega-science projects and the operation of mega-science devices.
