BEIJING, Nov. 1 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced early Tuesday that the launch of Shenzhou-8 unmanned spacecraft is successful.The spacecraft was successfully sent into the designated orbit after the blastoff at 5:58 a.m. at the Jiuquan Satellite Launch Center in northwestern desert area, carried by an upgraded Long March-2F rocket.It is heading to rendezvous with the Tiangong-1, or "Heavenly Palace-1" that was put into space on Sept. 29 for the country's first space docking.The docking, if successful, will pave the way for China to operate a permanent space station around 2020, and make the nation the world's third to do so.The launch was attended by Chinese Vice Premier Zhang Dejiang. It was also observed by senior experts from the European Space Agency and the German Aerospace Center at the launch site.The docking will happen within two days after the launch of the Shenzhou-8 at a height of 343 km above Earth's surface. The spacecraft will return to Earth after two docking operations.

ADDIS ABABA, Oct. 22 (Xinhua) -- China on Saturday delivered portion of the first batch of emergency food assistance to Ethiopia.Wei Hongtian, Charge d'Affairs at the Chinese Embassy in Ethiopia, handed over the assistance certificate to Wondirad Mandefro, Ethiopian State Minster of Agriculture, in a ceremony held at the Office of the Ethiopian Disaster Risk Management Food Security Sector (DRMFSS) in Addis Ababa, Ethiopia.The handover was witnessed by Ahmed Shide, Ethiopian State Minister of Finance and Economic Development, and Qian Zhaogang, Economic Counselor at the Chinese Embassy in Ethiopia as well as officials and diplomats from the two countries.The charge d'affairs said the Chinese government has decided to provide Ethiopia with two batches of gratis emergency food aid valued at some 24 million U.S. dollars, as part of humanitarian assistance to the people affected by drought in the Horn of Africa region, about which the international community is concerned much.Months ago, China pledged to provide humanitarian aid to drought affected people in Ethiopia, Kenya and Djibouti.The 2011 drought in the Horn of Africa region has affected livelihoods of over 12 million people in countries of the region including Ethiopia.In this move, China has delivered large quantities of wheat to Ethiopia, and it is put in the central warehouse in Adama town, 90 km away from Addis Ababa, as the first batch of the 8,139.4 tons of wheat and 715.15 tons of rice donated by the government of China, said Ethiopian State Minister of Agriculture.According to the minister, the Chinese government has pledged around 20,000 tons of emergency food valued at 24 million dollars.Wei said China attaches great importance to the agriculture development and the food security in Africa. He said China has engaged itself in various agricultural cooperations with African countries including Ethiopia, in different channels."In the future, besides food assistance, China's agricultural cooperation with Africa will focus on technology demonstration, personnel training, infrastructure construction, promotion of agricultural production and trade, and experience sharing agriculture development," said the Charge d'Affairs.The rest portion and the other batch of the emergency food assistance pledged by China is expected to come in November and December.Wei assured that the rest batches of emergency food aid would come to Ethiopia on schedule. The Ethiopian state minister said the Chinese government is one of those donors that demonstrated its strong friendship with the Ethiopian government and its people by extending appreciable humanitarian support at critical time."The recent donation of 100, 000 U. S. dollars by a Chinese private company, Huajin Group Ltd, for food aid is a manifestation that even private companies join us in our efforts to containing problems associated with such natural disasters," said Wondirad."Despite a steady economic growth achieved these past eight years in Ethiopia that reached an average of 11 percent annually and our continued efforts to maintain and accelerate the momentum through the GTP, we are confronted by climate change induced disasters, of which drought remains the major one," said the minister."While reducing disaster risk and vulnerabilities through development interventions, the government of Ethiopia in collaboration with its partners is taking all the necessary measures towards further enhancing its early warning and response system with the view to reducing potential impacts of disasters, including that of drought enhanced preparedness and provision of timely and appropriate responses."The government of the People's Republic of China has been one of our major development partners supporting us in all these efforts," he added.The state minister commended the Chinese government and its people for standing with Ethiopia shoulder to shoulder at the critical time by donating appreciable size of emergency food aid.

BEIJING, Oct. 12 (Xinhuanet) -- People are often recommended to eat plenty of fruits and vegetables, but only a minority people take the advice. A new research may motivate more people to do so.BBC reported a new study Tuesday that found eating lots of vegetables and fruits can weaken the effect of a gene variant called 9p21, which is reported to be one of the strongest predictors for heart disease, thereby reducing risks of heart disease.The researchers from McMaster and McGill universities studied the diets of more than 27,000 people around the world, including Europe, China, and Latin America.They found that people with the high-risk gene appeared to have a similar risk of heart disease as people with a low-risk variant of that gene after consuming a diet with a healthy amount of vegetables and fruits.But how diet has such an effect on the gene was unknown, said Dr. Sonia Anand, a lead author of the study published in PLoS Medicine journal.Anand added, "Despite having a high genetic risk for heart disease, a healthy lifestyle can actually turn off the gene."The message here is very clear, eating plenty of vegetables and fruits is definitely good to people's heart health, according to BBC.

BEIJING, Dec. 7 (Xinhua) -- The Chinese government on Wednesday released a white paper on its foreign trade, highlighting the country's achievements in boosting foreign trade and contribution to the world economy.The white paper, titled China's Foreign Trade, was released by the Information Office of the State Council.The white paper introduces China's historic progress, international contribution and policies in foreign trade.

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.
