SHANGHAI, May, 13 (Xinhua) -- Scientists attending a recent high-level conference on robotics agreed that great progress has been made in the field, but strict rules for the safe usage of robots should be implemented."Four years ago, if you went into a Chinese factory and said 'robots can help you work,' you would be kicked out. But now, China has a large industrial robot market, along with Japan, the Republic of Korea and the United States," says Li Zexiang, general chair of the 2011 International Conference on Robotics and Automation (ICRA 2011), which concluded Friday in Shanghai.Chinese robotics researchers have suggested to the government that rules and regulations for robot usage should be created. Professor Wang Tianmiao from the Beihang University (BUAA) told Xinhua about the suggestions during the conference.Wang says that in the future, it might not be possible for artificial intelligence to take the place of humans in some social roles. However, Wang says that mankind should pay close attention to the possible dangers of advancements in robotics, as the industry is currently undergoing dramatic changes.The five-day conference, which is organized by the Institute of Electrical and Electronics Engineers (IEEE), took place in China for the first time ever since its first session in 1984, which took place in the city of Atlanta in the United States.Media reports show that Japan, the Republic of Korea (ROK) and several Western countries have already drafted rules about the safe use of robots.

BEIJING, May 20 (Xinhuanet) -- Scientists have discovered a Jupiter-sized exoplanet that is completely unbound from a host star, according the scientific journal "Nature" published Thursday.The research was conducted by astrophysicists from Osaka University in Japan.Using the technique called "gravitational microlensing", scientists turned their telescopes towards the centre of the Milky Way and detected this "lonely planet" moving in a extremely large orbit, which suggested it does not connect to any solar system.Then they estimated the total number of such wondering planets could be as many as 400 billion, based on the detection efficiency. This number far outnumbers the main-sequence stars such as our Sun."This is an amazing result, and if it is right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut.And scientist began to consider the possibility that liquid water could exist on this kind of unbound planets. "That might be an attractive possibility for life," said David Stevenson, a planetary scientist at the California Institute of Technology.

CAIRO, Jan. 23 (Xinhua) -- As part of bilateral efforts to enhance cultural cooperation between the two great civilizations, China, as the Guest of Honor, will participate in the 43rd Cairo International Book Fair in Egypt."An outstanding Chinese delegation will attend the fair to inform the Egyptian people all about Chinese culture," said Chen Dongyun, cultural counsellor of the Chinese Embassy in Egypt.Some 248 publishers, 13 renowned scholars, writers and artists will display about 10,000 books about the achievements made by China in various fields such as politics, economy, science and technology, and culture.The fair, the most important of its kind in the Arab region, will be held on Jan. 29 through Feb. 8 in the Cairo International Conference Center. The annual fair began in 1969.The Chinese hall in the center covers an area of 1,400 square meters, with special areas allocated for a variety of exhibitions about the history of the evolution of Chinese characters, photos reflecting Sino-Egypt friendship and landscape of modern China and intangible cultural heritage.The fair also includes a seminar featuring literature and translation among Chinese and Egyptian writers and artists and a week-long film show in which six Chinese films with Arabic subtitles will be introduced to the audience.Chinese participation reflected the common consensus of the leaders of the two countries to deepen mutual understanding and friendship and will serve to promote the sound and sustainable development of bilateral relations, Chen said.Zhang Jichen, vice president of China National Publications Import and Export (Group) Corporation, which is in charge of the organization of the Chinese activities at the fair, said a cooperation agreement between the General Administration of Press and Publication of China and Egypt's Ministry of Culture.China will also present some 1,000 high-quality books to the National Library and Archives of Egypt and the Alexandria Library.The fair is expected to attract 632 publishers from 29 countries, including 17 in the Middle East. More than two million visitors participate in the fair each year.

BEIJING, Feb. 13 (Xinhua) -- Snow fell again in Beijing Saturday night, three days after the city had its first snow this winter.Snow continued falling on Sunday morning but was forecasted to stop in the daytime.From 8:00 p.m. Saturday to 8:00 a.m. Sunday, precipitation in Beijing averaged 1.7 mm to 3.1 mm in downtown areas, local meteorologists said.Zhang Qiang, head of the municipal artificial weather intervention office, said the office began cloud seeding and was continuing efforts to increase snowfall from 7:25 p.m. Saturday in the nine districts and counties of Miyun, Mentougou, Yanqing, Haidian, Pinggu, Changping, Shijingshan, Fangshan and Huairou.By 8:20 a.m. Sunday, 657 silver iodide rods had been used to increase the snowfall.More than 3,583 people and 768 vehicles have been mobilized since Saturday to clear the snow on major roads of Beijing to ensure road transportation, according to the city transportation departments.Beijing had its first snow of the winter Wednesday and Thursday after 108 days of zero precipitation.Meteorologists said the snowfall in Beijing had helped ease the pressure of drought."Beijing is expected to have another cold front from Feb. 15 to Feb. 16, but it is not sure if there will be another snowfall then," said Liao Xiaonong, chief weatherman with the Beijing Meteorological Bureau.

CANBERRA, March 23 (Xinhua) -- Up to 45 native species in Western Australia's Kimberley region will die out within 20 years if no action is taken, latest study showed on Wednesday.The Priority Threat Management to Protect Kimberley Wildlife report, released by Commonwealth Scientific and Industrial Research Organization (CSIRO) on Wednesday, was commissioned by the Wilderness Society.The report showed that at present, 20.2 million U.S. dollars a year is spent on conservation efforts in the Kimberley, which is home to an assortment of threatened species.However, the report said even if that money was spent properly, the region would still lose some 31 native animals.The numbers of many more birds, reptiles and mammals, such as the Spotted Tree Monitor and the Western Chestnut Mouse, would dwindle.It called for an immediate cash injection of 96 million U.S. dollars to save creatures like the Golden Bandicoot, the Scaly- Tailed Possum and the Monjon Rock Wallaby from extinction.It will follow by an ongoing investment of 40.43 million U.S. dollars annually in the Kimberley to protect its species, as well as boost plant life, help the climate and conserve indigenous land."This investment is great value," one of the report's six co- authors Hugh Possingham said in a statement released on Wednesday."We can save some of Australia's most iconic mammals and birds at a cost of only about one million U.S. dollars per species per year."
