ADDIS ABABA, Nov. 15 (Xinhua) -- The African Union (AU) Commission Chairperson Jean Ping on Tuesday met and held talks with a high level Chinese delegation led by Jiang Yaoping, Chinese Vice Minister of Commerce.The discussion between the two sides was mainly focused on the cooperation between China and Africa in different sectors.Ping said AU is ready to do all possible to further strengthen its ties with China.The Chairperson said China has been working in cooperation with AU member states on various areas, including trade, investment, and diplomatic exchanges."We are happy to meet the delegation; a delegation not only as an important partner but as a friend of Africa, a friend with which we are strengthening cooperation constantly," said the Chairperson.He also reiterated that Africa is benefited from the relations with China.He said Africa has established an important relations with China within the China-Africa Cooperation Forum (FOCAC), and the two sides are now engaged in strategic dialogue on very crucial areas.Jiang said that AU has been committed to economic integration in Africa that enable member states improve the livelihoods of Africans.He also said that AU has played a constructive role in meeting global issues like the climate change.The Vice Minister stated that China has become one of the most trading partner of Africa, and the trade volume between China and Africa is increasing from time to time.Leading the delegation, Jiang has also visited the African Union Conference Center (AUCC) Project which is almost completed and is expected to be the avenue of the coming AU Summit for the first time at its own headquarter.

SAN FRANCISCO, Nov. 28 (Xinhua) -- Amazon.com on Monday announced that this past Black Friday was the best ever for its Kindle products with consumers buying four times as many Kindle e- readers and tablets as they did last year.According to the online retail giant, its newly launched tablet Kindle Fire was the bestselling product across all of Amazon.com on Black Friday, the day after Thanksgiving, which falls on Nov. 25 this year, when major retailers in the United States traditionally offer big discounts.Kindle Fire is Amazon's answer to Apple's popular iPad. Priced at 199 U.S. dollars, the Amazon product is much cheaper than iPad which starts from 499 dollars.Survey results by research firm ChangeWave Research released days before Black Friday indicated that Amazon is poised to become the No. 2 player in the tablet computer market behind Apple, due to strong demand for Kindle Fire.Amazon said Black Friday sales also showed that a lot of customers were buying multiple Kindles, one for themselves and others as gifts.The trend is expected to continue through this holiday shopping season, Amazon's vice president of Kindle products Dave Limp said in a statement.

BEIJING, Nov. 7 (Xinhua) -- Chinese President Hu Jintao will meet with his U.S. counterpart, Barack Obama, at the 19th Asia-Pacific Economic Cooperation (APEC) Informal Leadership Meeting, said China's Assistant Foreign Minister, Wu Hailong, on Monday.He said the APEC summit will be held from Nov. 12 to 13 in Hawaii, with the theme of "seamless regional economy."According to Wu, speaking at a Foreign Ministry media briefing, Hu will attend the "APEC Leaders' Informal Meeting, Leaders' Dialogue with Representatives from APEC Business Advisory Council, and APEC CEO Summit."China hopes the APEC members will implement the economic growth strategy agreed last year, striving to achieve a balanced, inclusive, sustainable, innovative and safe economic growth, said Wu.China expects the APEC members to comprehensively promote regional trade and investment liberalization, he said, adding that all member states should fulfill their commitments and oppose all forms of trade protectionism.Wu said APEC should strengthen economic and technical cooperation to enhance the development ability of the developing members, and therefore to achieve common prosperity."APEC members generally hold positive attitudes toward U.S. proposals in various fields such as green growth, innovation policy. But some of the U.S.'s expected outcomes are beyond the capacity of the developing members, and they have expressed their difficulties and concerns," Wu said."However, all parties hope this meeting will achieve balanced and practical results".Assistant Commerce Minister Yu Jianhua said major topics to be discussed at the summit would include pushing forward the Doha Round negotiations, opposing trade protectionism, promoting green growth, and cooperation on developing regulations to govern emerging industries.He said China hopes the meeting will further promote the liberalization and facilitation of 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.On safeguarding the multilateral trade system, Yu said the decade-long Doha round talks have entered a critical period and the summit should be a strong voice for the early completion of the talks as well as joint resistance against trade protectionism.He said the APEC members should make joint efforts to remove discriminatory trade restrictions on high-tech products, and promote technology transfer and cooperation, so as to enable all members to benefit.On green growth, he said as APEC members differ sharply in their basis, conditions and levels in developing a green economy, the liberalization of environmental products and services should be pushed steadily.He also called on the developed economies to enhance capital and technical support for the developing economies, helping them in achieving their potential for sustainable development.

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.

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.
