BEIJING, Nov. 25 (Xinhua) -- The Ministry of Commerce (MOC) said Friday that it will start an investigation into the U.S. government's policy support and subsidies for its renewable energy sector over trade barrier concerns.The MOC will look into six renewable energy programs concerning wind, solar and hydroelectric energy in the states of Washington, Massachusetts, Ohio, New Jersey and California, the MOC said in a statement posted on its website.The investigation was applied for by the China Chamber of Commerce for Imports and Exports of Machinery and Electronic Products, as well as the new energy chamber of the All-China Federation of Industry and Commerce."The applicants argued that the U.S. government's policy support and subsidies for its renewable energy industry constitute a trade barrier, as they violate the rules of the World Trade Organization and have hindered and restricted the development of China's renewable energy sector," the statement said.The applicants requested the elimination of any negative influence from the U.S. government's policy support and subsidies in order to maintain a fair trade environment, according to the statement.The investigation will end before May 25, 2012, although it may be extended to August 25, 2012 under special circumstances, according to the statement.

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.

WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

BEIJING, Sept. 30 (Xinhuanet) -- Tobacco companies concealed the knowledge of radioactive substance in cigarettes from public for over four decades, a new study revealed.The revelation was made by a research team from the University of California, Los Angeles, published on Thursday in the online edition of the U.S. medical journal Nicotine and Tobacco Research.The researchers analyzed 27 timeworn documents and discovered that tobacco companies had knew the existence of polonium-210, a hazardous radioactive substance, in the tobacco since 1959.The companies studied polonium-210 throughout the 1960s, and concealed their findings about the carcinogenic potential of the radioactive substance.Hrayr Karagueuzian, the study's lead author, said the tobacco companies' deception surprised him.According to the revelation, the companies had knew the "cancerous growths" in the lungs of smokers, and even calculated how much radiation a regular smoker would inhale over 20 years.Karagueuzian and his team conducted again the study recorded in the tobacco documents and found that the radiation in cigarettes would cause up to 138 deaths for every 1,000 smokers over a period of 25 years.However, tobacco manufacturer denied that they had concealed the facts from the public.David Sutton, spokesman of Philip Morris, the largest U.S. tobacco company, said the polonium-210 was a "naturally occurring element in the air" and had been widely discussed by the public health community for years.

HONOLULU, United States, Nov. 12 (Xinhua) -- Chinese President Hu Jintao said here Saturday that China will deepen economic structural reform, grow a green economy, enhance protection of intellectual property rights and open wider to the outside world.Hu made the remarks at the CEO summit of the Asia-Pacific Economic Cooperation (APEC) ahead of the APEC Economic Leaders' Meeting.Hu noted that while China's economy has grown steadily and the country is opening wider to the outside world, China still faces the major challenge of unbalanced, uncoordinated and unsustainable development.China, he said, will continue to deepen reform and opening-up, improve people's livelihood and promote sustained, steady and fairly fast economic growth and social harmony and stability.Hu then laid out a four-point proposal to achieve the goals, with the first being that China will deepen economic structural reform and improve business and investment environment.Second, China will honor its commitment to growing a green economy and promoting the conservation culture, Hu said.From 2011 to 2015, China's investment in the environmental sector will double that of the previous five years to about 3.1 trillion yuan (about 488.5 billion U.S. dollars), Hu said, adding that China's green industry is a key area for foreign investment.Third, China will step up protection of intellectual property rights and make itself a country driven by innovation, he said.China will vigorously boost scientific and technological innovation and turn enterprises into major players of such innovation, while further improving the legal system for intellectual property rights protection, he said.Fourth, China will open wider to the outside world and take an active part in global economic governance and regional cooperation, Hu said.China, he said, will give equal importance to import and export and focus more on increasing import while maintaining a stable level of export.Noting that China's development constitutes an important force driving regional and global economic growth, Hu said that China will work together with others to create a better future for the Asia-Pacific region.
