JERUSALEM, Oct. 24 (Xinhua) -- A recent study carried out by Israeli researchers showed that the experience of motherhood is caused by alterations in the brain functions that help mothers locate and communicate with their offspring, especially if they are in distress.Researchers at the Hebrew University of Jerusalem said the results provide insight into how neural changes in response to odors and sounds help maternal behaviors develop in mothers."We know that distinct brain changes are linked with motherhood, " Dr. Adi Mizrahi, who conducted the research, said, "but the impact of these changes on sensory processing and the emergence of maternal behaviors are largely unknown."Mizrahi and his colleagues examined whether the primary auditory cortex -- a region in the brain that is involved in the recognition of sounds -- might serve to process the responses to their offspring's specific smell and voice.The research proved that the olfactory and auditory senses of female mice with their pups were triggered immediately after they gave birth, with especially strong responses to cries of distress."These processes help to explain how changes in the cortex in the brain facilitate efficient detection of pups," Mizrahi said.

BEIJING, Oct. 12 (Xinhuanet) -- Study found that women who took multivitamins may actually be at risk, media reports on Wednsday.Women who took the dietary supplements vitamin B6, folic acid, magnesium, zinc, copper, iron and multivitamins had a higher risk of death than women who did not.The new study, published in the Archives of Internal Medicine, examined more than 38,000 women aged 55 and older who took part in the Iowa Women's Health Study, which started in the mid 1980s. Researchers found the vitamins did nothing to reduce the risk of death and that most supplements have no positive effect on women's health.The study did not distinguish if the women in the study took the vitamins to fight diseases or to maintain health.Vitamin experts say the best way to make sure you are getting all necessary vitamins is to eat a well-balanced diet. The vitamins people take do not  depend on personal preference.

UNITED NATIONS, Oct. 17 (Xinhua) -- China on Monday underlined the importance of safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space, saying that "the outer space is the common wealth of mankind as the global public space."The statement came as Wang Qun, the Chinese ambassador for disarmament affairs, was taking the floor at the thematic debate on outer space at the First Committee of the UN General Assembly. The First Committee is in charge of disarmament and international security."The outer space is the common wealth of mankind as the global public space," Wang said. "The permanent peace of outer space is correlated to all nations' security, development and prosperity.""Meanwhile, with the growing reliance of mankind on outer space, the risk of the weaponization of and an arms race in outer space are on rise, and the uncertainties concerning outer space security are accumulating as well," he said. "Safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space are common interest and obligations of all countries."In responding to the growing challenge for security in outer space, the international community also witnessed common grounds on opposing to the weaponization of outer space and advertising the Prevention of an Arms Race in Outer Space, he said.The General Assembly, for consecutive years, adopted " Prevention of an Arms Race in Outer Space" resolution by overwhelming majority of votes, calling for negotiations on an international legally-binding instrument on the prevention of an arms race in outer space at the Conference on Disarmament in Geneva."The mankind has marched into the 6th decade of outer space exploitation, and the manned space flight has made a history of 50 years," Wang said."Recently, China has successfully launched the Tiangong-1 ( Heavenly Palace 1) as a target spacecraft for rendezvous and docking experiment, which opens a new era of China's manned space flight, and also reflects that China is committed itself to the honorable objective of promoting the peaceful exploration and utilization of the outer space, maintaining peace and bringing benefit to mankind."

BEIJING, Nov. 6 (Xinhua) -- Employment quality in China is relatively low, which is a major reason affecting the quality of economic growth, says a latest report on the labor market.The report, released Saturday by the Labor Market Research Center of the Beijing Normal University focusing on the quality of employment in China, says Beijing, Shanghai and Tianjin were the top three cities in terms of employment quality, adding the overall employment quality in China is still low."Poor employment quality in China is a major reason for the poor quality of economic growth," said Lai Desheng, a professor with the Beijing Normal University.

BEIJING, Nov. 3 (Xinhua) -- Two Chinese spacecraft accomplished the country's first space docking procedure early Thursday, silently coupling in space more than 343 km above Earth's surface.Nearly two days after it was launched, the unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 at 1:36 a.m., marking another great leap for China's space program.The success of the docking procedure makes China the third country in the world, after the United States and Russia, to master the technique, moving the country one step closer to establishing its own space station.A video grab taken from the China Central Television on Nov.3, 2011 shows the Shenzhou-8 spacecraft docking with the Tiangong-1 space lab module. Unmanned spacecraft Shenzhou-8 docked with space lab module Tiangong-1 early Thursday, according to the Beijing Aerospace Control Center.President Hu Jintao, who is in France for the G-20 summit, sent a congratulatory message on the success of the country's first-ever space docking."Breakthroughs in and acquisition of space docking technologies are vital to the three-phase development strategy of our manned space program," Hu said in the message.Hu said he wishes all the program participants to try all out to fulfill a complete success of the whole mission after the smooth docking.Other leaders, including Wu Bangguo, Wen Jiabao, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, who are Standing Committee members of the Political Bureau of the Communist Party of China Central Committee, watched the mission at the Beijing Aerospace Flight Control Center.China is now equipped with the basic technology and capacity required for the construction of a space station, said Zhou Jianping, chief designer of China's manned space program."This will make it possible for China to carry out space exploration on a larger scale," he said."The capability increases China's ability to act independently in space, as well as its ability to cooperate with others," said Gregory Kulacki, senior analyst and China project manager at the global security program of the Union of Concerned Scientists, a nonprofit scientific advocacy group based in the United States."China's pursuit of an original solution to space docking, that is based on their understanding of the experience of other nations, could lead to innovations or experiences other space-faring nations could find useful," Kulacki said.The world's first space docking was achieved in 1966, when the manned U.S. spacecraft Gemini 8 docked with an unmanned Agena Target Vehicle.Forty-five years later, the maneuver remains a technological challenge. Many of mankind's 300-plus attempts have been met with difficulties or resulted in failure."To link up two vehicles traveling at 7.8 km per second in orbit, with a margin of error of no more than 20 centimeters, is like 'finding a needle in a haystack'," Zhou said.The Shenzhou-8 and Tiangong-1 will separate after flying together for 12 days. After that a second docking procedure will be conducted.Rendezvous and docking, essential to exploring space beyond Earth's orbit, create the possibility of building space stations, resupplying them, transferring astronauts and rescuing them.Without this key know-how, exploration of the moon and beyond requires carrier rockets with significant amounts of thrust. China does not currently possess rockets of this magnitude.Shenzhou-8 and Tiangong-1 both weigh about 8 metric tons, well within the delivery capacity of the Long March 2F rocket. A permanent orbiting space station is designed to be as heavy as 60 metric tons, with docking ports accommodating both manned and freight space vehicles.The interior of both the Shenzhou-8 and Tiangong-1 is an actual environment in which astronauts can live and work. After the Shenzhou-8 tests, the Tiangong-1 will remain a target orbiter for more docking procedures in 2012 by the Shenzhou-9 and -10 spacecraft, at least one of which will be manned to conduct manual docking.Although the Shenzhou-8 is unmanned, it is equipped with devices to record images and data that will help China make improvements to its spacecraft design and astronaut training.Two female astronauts are now believed to be on the active duty roster for future Shenzhou missions, said Chen Shanguang, director of the Astronaut Center of China (ACC)."We must assess both male and female astronauts to verify if human beings can live in space, as there are huge differences between men and women in spite of their common generalities," Chen said."Space exploration activities would be incomplete without the participation of female astronauts," Chen said.The Chinese spacecraft also feature collaborative space experiments under the framework of a Chinese-German science and technology cooperation.German scientists designed bio-incubators for the experiments, while their Chinese counterparts were in charge of the development of control equipment, China's manned space program spokeswoman Wu Ping said.
