SHIJIAZHUANG, Oct. 16 (Xinhua) -- Chickens began being domesticated in China about 8,000 years ago, far earlier than in the rest of the world,according to a recent study on fossils uncovered in north China's Hebei Province.Archaeologists said they had unearthed 116 fossil specimens from 23 types of animals, including pig, dog, chicken, tortoise, fish, and clam, at the Cishan Site, a Neolithic village relic in the city of Wu'an.Several bone fragments were identified to be from domesticated chickens, said Qiao Dengyun, head of the Handan Municipal Institute of Cultural Relics and Archaeology."The chicken bones found at Cishan are slightly larger than wild jungle fowls, but smaller than that of a modern domesticated chicken," said Qiao.Qiao said the bone fossils date back to 6,000 BC, earlier than the oldest domesticated chicken previously discovered in India that dated back 4,000 years."Most of the bones were from cocks, indicating that ancient residents used the practice of killing cocks for their meat and raising hens for their eggs," said Qiao.The Cishan Site, which dates back 10,000 years, was first discovered in the 1970s. At the site, experts have found remnants of China's oldest cultivated millet as well as walnut shells, a discovery that challenged the popular belief that walnuts had been brought to China from what is now Xinjiang Uygur Autonomous Region and Central Asia.

RIYADH, Jan. 14 (Xinhua) -- China and Saudi Arabia pledged to work together to further expand all-around exchanges and cooperation as Chinese Premier Wen Jiabao Saturday unfolded his official visit to the Middle East kingdom.China and Saudi Arabia have treated each other as equals with respect and their cooperation has been fruitful since the establishment of diplomatic ties 22 years ago, said Wen while meeting Crown Prince Nayef bin Abdulaziz Al Saud.In recent years, despite the fact that international and regional situation became ever complicated and volatile, the two countries have strengthened high-level exchanges and promoted political mutual trust, said Wen, adding that the two have always demonstrated mutual understanding and support on issues involving their core interests and of major concern.Chinese Premier Wen Jiabao (L) holds talks with Saudi Arabia's Crown Prince Nayef bin Abdulaziz Al Saud in Riyadh, Saudi Arabia, Jan. 14, 2012.The premier said the decision to lift bilateral ties to an even higher level has shown the two nations' firm commitment to jointly face challenges and protect common interests as the world situation is undergoing profound changes.China would like to work with the Saudi side in deepening exchanges and cooperation in various aspects so as to benefit the two peoples and promote world peace and development, Wen added.He said the two sides should expand trade of crude oil and natural gas and energy-related cooperation as to deepen their energy partnership.Wen also asked the two countries to promote investment cooperation. The Chinese government encourages well-established Chinese companies to participate in Saudi Arabia's infrastructure construction such as railway, sea ports, electricity and telecommunications, he said.The two nations could also enhance security and law enforcement cooperation and promote people-to-people exchanges in areas like education and sports, as well as between the two nations' youths.Nayef said Saudi Arabia and China enjoy a time-honored history of exchanges, adding that the Saudi people have friendly feelings toward the Chinese people and expect even better bilateral ties.With joint efforts, bilateral ties have moved forward continuously with remarkable achievements in bilateral cooperation, he said, added that the partnership has bright prospects.Nayef said Saudi Arabia is willing to further boost political mutual trust with China, expand bilateral cooperation in economy and trade, energy, infrastructure, culture, press, and security, promote friendship between the two peoples, and lift bilateral ties to a higher level.Wen arrived here on Saturday evening after a short official visit to Nepal on the same day.

BEIJING, Jan. 05 (Xinhuanet) -- Tighter licensing and banning unlicensed food processors are two measures needed to improve the poor quality of cooked food in Guangzhou markets, says a new proposal.The proposal, to be presented to the Guangzhou committee of the Chinese People's Political Consultative Conference, notes that producers of unpacked cooked food currently only need to obtain a food circulation permit.Many of them process food in unlicensed workshops with poor sanitation, and some producers even use substandard materials in food processing.The annual session of the conference opens on Tuesday.Recent tests of unpacked cooked food found that of 100 samples of meat, flour-based food, preserved vegetables, soybean products and algae products, only 38 passed the inspection.No cold dried bean curd or cold algae products passed the tests, which were carried out at seven supermarkets in Guangzhou, Guangdong province, by the city's consumers' commission.Excessive microorganisms were the main reason for failing the tests. Fifty-five samples contained excessive coliform and 12 had golden staph.Meanwhile, in tests of unpacked cooked food at supermarkets in Guangzhou by the city's commerce authority in the third quarter of last year, only 28 of the 71 samples passed the tests. In addition to excessive bacteria, excessive use of coloring agents was also spotted.The situation at other markets, such as wet markets, is more worrying, says the proposal.It also suggests that separate cooked food processing areas be built in local markets, with closer scrutiny over them.Standards concerning the processing, storage and transport of those food products remain unspecified.Some supermarkets, on the other hand, have been lax in selecting suppliers and failed to install protective facilities in shelving the food.Given that a number of government agencies are involved in food safety work, the proposal suggests that a shared information platform be built to prevent loopholes.The food associations should also play a bigger role in supervising food enterprises, it says."Since cooked food goes through the production, transport and shelving steps, it is hard to guarantee the quality. Even packed food has quality problems, not to mention unpacked food," said Ding Honghui, a resident who was shopping at a supermarket in Guangzhou."As far as I know, many government departments are involved in safeguarding food safety. They should strengthen the supervision and work more closely," he said.

HONOLULU, United States, Nov. 10 (Xinhua) -- Chinese President Hu Jintao arrived in Honolulu, Hawaii, on Thursday for the Economic Leaders Meeting of the Asia-Pacific Economic Cooperation (APEC), slated for Saturday and Sunday.At the annual meeting, leaders of the 21-member group will exchange views on economic growth in the Asia-Pacific region, strengthening regional economic integration and expanding trade.They will also consider the promotion of green growth and fostering job creation in green industries, energy security, and expanding regulatory cooperation and advancing regulatory convergence.Chinese President Hu Jintao (C) arrives in Honolulu, Hawaii, U.S., Nov. 10, 2011. Chinese President Hu Jintao arrived in Honolulu, Hawaii, on Thursday for the Economic Leaders Meeting of the Asia-Pacific Economic Cooperation (APEC), slated for Saturday and Sunday.President Hu is expected to speak at the meeting and express his views on the world economic situation and the regional economic situation, Wu Hailong, assistant foreign minister of China, said at a press briefing earlier this week.In his speech, Wu said, the Chinese leader will call for "improving global economic governance, shifting the growth method, promoting economic globalization and regional economic integration."Hu will also explain "China's stand on the issues of free and open trade and investment, green growth, the adjustment of economic structure and regulatory cooperation," Wu said.In Hawaii, Hu will join other APEC leaders in dialogue with the APEC Business Advisory Council (ABAC).APEC leaders are expected to discuss with ABAC representatives, among other things, regional economic integration, reform of the international monetary system, and food security.The Chinese leader is scheduled to deliver a speech at the APEC CEO summit Saturday.On the sidelines of the APEC Economic Leaders Meeting, President Hu will meet U.S. President Barack Obama and other leaders of APEC members."China hopes the meeting will further promote the free and open trade and investment in the Asia-Pacific region, push forward economic and technology cooperation, support multilateral trade systems, oppose trade protectionism, so as to inject vitality into world economic recovery and growth," Assistant Commerce Minister Yu Jianhua said at a press briefing earlier this week.APEC is the premier economic forum in the Asia-Pacific region.Since APEC's birth in 1989 it has grown to encompass 21 members spanning four continents, and represents the most economically dynamic region in the world, accounting for approximately 40 percent of the world's population, around 50 percent of world GDP and about 44 percent of world trade.APEC's 21 member economies are Australia, Brunei, Canada, Chile, China, China's Hong Kong, Indonesia, Japan, Republic of Korea, Malaysia, Mexico, New Zealand, Papua New Guinea, Peru, the Philippines, Russia, Singapore, Chinese Taipei, Thailand, the United States and Vietnam.

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.
