BEIJING, Nov. 4 (Xinhuanet) -- The amount of trans fat and other nutritional information will be marked on the labels of prepackaged food, according to the country's first national standard for food nutrition. The labeling will take effect on Jan 1, 2013. "It will help standardize the nutrition facts labeling by food producers and facilitate consumers' rights to know and choose, while improving public awareness of food nutrition," said Yang Yuexin, a senior nutritionist with the Chinese Center for Disease Control and Prevention (CDC). The new regulation by the Ministry of Health stipulates that food labels have to include the food's nutrition information, including levels of energy, protein, fat, carbohydrate and sodium. Food products without proper labels showing the nutritional information will be banned when the new rule takes effect. The new regulation also stipulates that if any hydrogenated or partially hydrogenated fat is used to produce the food, the level of trans fat will have to be highlighted on the nutrition information label. Trans fat is usually produced during food processing when liquid oils are converted into semi-solid fats that help keep food fresh longer. However, the partially hydrogenated oil contains trans fat that can substantially increase the risk of heart disease. However, Zhang Jian, a researcher with CDC's National Institute for Nutrition and Food Safety, said that compared to Western diets, the Chinese diet contains a far lower level of trans fat and there is no need to over react.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

BEIJING, Nov. 13 (Xinhua) -- China has established an operation committee for management of the country's first space lab module, Tiangong-1, during its two-year orbit of earth.The committee will deal with operations planning, technical appraisal and flight control of the target orbiter after the unmanned Shenzhou-8 spacecraft returns to earth after its mission, the official website of China's manned space program said.The Tiangong-1 space lab module was launched on Sept. 29 and docked with Shenzhou-8 precisely on Nov. 3, China's first ever space docking attempt. The second docking between Tiangong-1 and Shenzhou-8 is scheduled for Nov. 14.The manned space program said earlier that the same target orbiter Tiangong-1 will accommodate another two docking missions performed by two other Shenzhou spaceships, at least one of which will be manned.The 8.5-tonne Tiangong-1 is the first space lab module that China has built, and the committee will also be the first in taking care of a long-running space asset.The operation committee for Tiangong-1 heralds China's manned space program entering a new phase for lengthy flight missions, Niu Hongguang, director of the operation committee, said on the website www.cmse.gov.cn.The orbiting module management will include taking care of the space lab, making preparations for any further docking tests and gathering experience for building a future space station, Niu said.

BEIJING, Oct. 14 (Xinhuanet) -- Materialism could be harmful to marriage, according to a new study published in the American Journal of Couple & Relationship Therapy Thursday.The researchers collected online "relationship assessment" questionnaires from 1,734 U.S. married couples.The questionnaire covered the topics about the couples' marital satisfaction, conflict patterns, marital communication, and marriage stability, and so on.Non-materialistic couples were about 10 to 15 percent better than those materialistics in their marital satisfaction, marriage stability and conflict levels, according to the study."What we found was a general pattern that materialism seems to be harmful to marriage," said study researcher Jason Carroll, a professor of family life at Brigham Young University.It didn't matter whether the materialistic spouse was the man or the woman, he added.However, materialism is not simply black-or-white: some couples can pursue their fortune and keep their relationship strong at the same time, the researcher suggested.But breaking their materialistic thought would be helpful for most couples, Carroll concluded.

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.
