BEIJING, July 1 (Xinhuanet) -- China must adopt a holistic approach to addressing food safety challenges connected to the risk of contracting infectious diseases from contact with animals, the World Health Organization (WHO) has said. Peter Ben Embarek, food safety officer at WHO's China office, said the country faces risks connected to the need to produce more meat, eggs and milk to feed its growing population. He said the increased production will ramp up the risk of people being infected by food-borne diseases because of poor slaughtering oversight and the absence of proper surveillance and inspection systems. About 50 percent of pigs in China are slaughtered outside of formal facilities without the inspection of veterinarians or food safety officers. He said poorly trained producers have little or no awareness of food safety or the risk of animal diseases being passed on to humans. Such an environment could lead to the emergence of a new pandemic of influenza. During the past 60 years, 30 percent of the 335 new infectious diseases worldwide were transmitted through food, he said. Yet in many parts of China, public awareness remains low about such things. Xu Aixiang, a 35-year-old resident of Rizhao city in Shandong province, prefers to buy live poultry at local markets. Like many of her neighbors, she takes the chickens she buys home to slaughter them. "I get fresher chickens that are better quality this way," she said. "When vendors sell slaughtered chickens, the meat is no longer fresh and may have had water injected into it to make it heavier." But Ben Embarek cautioned that such live-animal markets are high-risk places for the exchange of viruses and diseases between animals and humans. He said simple and cost-effective measures can be taken to improve such markets' hygiene standards, such as the installation of separate areas to keep live poultry away from customers as well as improving air flow and waste management. Several UN agencies, including the WHO and the Food and Agriculture Organization, called on China to adopt an integrated approach to preventing emerging epidemic diseases and maintaining ecosystem integrity at an event themed "One Health" that convened on Wednesday in Beijing. At the gathering, representatives from the Ministry of Health, the Ministry of Agriculture and the Chinese Center for Disease Control and Prevention shared experiences from efforts to mitigate the H5N1 and H1N1 influenza outbreaks in China and said they were committed to working together in the future. Su Jingliang, an associate professor of preventive veterinary medicine at China Agricultural University, said his lab had detected the outbreak of a new type of flavivirus in ducks that led to a significant fall in egg production at farms in Beijing as well as in Hebei, Jiangxi and Shandong provinces. The pandemic was brought under control in March. No cases of humans contracting the disease have been reported so far but Su said he was concerned about the possibility of farmers becoming infected through close contact and long exposure to sick ducks. He said precautionary measures should be taken in cooperation with the Ministry of Health and other government agencies and checks should be run on people who are at high risk.

BEIJING, Sept. 27 (Xinhuanet) -- Last-minute preparations for the launch of the Tiangong-1 spacecraft began at the Jiuquan Satellite Launch Center on Monday, meaning the vehicle can soon embark on a mission that will eventually have it dock with a spaceship, according to the center.That feat, if carried out successfully, will mark the completion of China's first rendezvous and docking mission.At the launch site on Monday afternoon, crews were putting in place pipes and cables that will be used to inject fuel into the rocket that will carry Tiangong-1 into outer space.Without complications from the weather or other causes, the Long March II-F rocket will lift off from the launch center on Thursday or Friday, taking the Tiangong-1 with it, according to the Xinhua News Agency.Despite the preparations, space experts said carrying out the plan still comes with many risks. They explained that the spacecraft and much of the other equipment being used is new and has not been tried on an actual mission."Tiangong-1 is a brand new spacecraft designed by China and is bigger and heavier than the Shenzhou spaceships China had developed as a means of transporting astronauts from the Earth to space," said Yang Hong, chief designer of Tiangong-1.In a vertical position, the Tiangong-1 looks like a cigar standing 10.4 meter tall, a height equal to that of a three-story building. It weighs 8.5 tons and has a maximum diameter of 3.35 meters, a dimension shared by its launch vehicle, he said.In comparison, the Shenzhou spaceship stands shorter, at nearly 9 meters, is slimmer, having a diameter of less than 3 meters, and weighs less.In another difference, the Tiangong-1 is composed of two modules rather than the three that had made up the Shenzhou spaceship. Of the Tiangong-1's two primary components, one is an experimental module that contains a place that astronauts can live and work in on future missions. It is also equipped with a docking port.The other chief component, a resource module, will provide the craft with power.Astronauts on Tiangong-1 will have 15 cubic meters of space to move in, "much more than they had in the Shenzhou spaceship", Yang said.Inside the spacecraft are two sleeping sections with adjustable lighting systems, exercise equipment, entertainment systems and visual communication devices, he said.Hou Xiangyang, who helped design Tiangong-1, said: "The sleeping section is big enough for a 1.8-meter-tall man to sleep in. An astronaut can adjust the light as he likes."In space, Tiangong-1 will fly in a horizontal position. A paint scheme inside will help the astronauts aboard maintain their sense of direction; the module's inner walls will be in two colors, one commonly associated with the sky and one with the ground."This will help astronauts avoid feeling as if they are standing upside down in the microgravity environment," he said.Yang said the Tiangong-1 spacecraft is expected to stay in orbit for two years and rendezvous and dock with three different spaceships. Beyond the Shenzhou VIII, ships named Shenzhou IX and Shenzhou X will embark on similar missions; at least one of the two is to be manned.Before astronauts climb on board Tiangong-1, the conditions inside its experimental module will be adjusted to ensure they can live in an environment that contains enough oxygen, moisture and heat to be safe.Tiangong-1 was originally scheduled to be launched into a low orbit around the Earth between Sept 27 and 30. The earlier days were removed as possible launch dates, though, after forecasters predicted a cold air mass would move into the area containing the Jiuquan Satellite Launch Center.To ensure the spacecraft and Long March II-F carrier rocket are ready for launch, a full ground simulation was conducted on Sunday afternoon.

BEIJING, Sept. 4 (Xinhua) -- Officials and delegations from China and African countries have gathered at a seminar being held in Beijing to discuss rural development and economic growth.The seven-day seminar kicked off on Sunday, attracting representatives from China and 11 African countries to exchange views and experiences related to the seminar's theme of "agriculture and rural development."Justin Lin Yifu, chief economist and senior vice president of the World Bank, said at the seminar's opening ceremony that African countries should take cues from China's experience in creating a series of policies to bolster agricultural and rural development, as these policies have also facilitated the country's economic growth.Hu Jinglin, assistant to China's Minister of Finance, said improved agricultural cooperation between China and Africa will help enhance global grain security.China has worked on 142 cooperative agricultural projects with 14 African countries to date. In addition, it has sent 104 agricultural experts to 33 African countries to train more than 4,200 local agricultural technicians.

BEIJING, May 31 (Xinhuanet) -- European anti-trust regulators Monday launched in-depth probes into takeover bids for two Asian companies by two American peers in the computer hard disk drive sector, media reports said Tuesday.U.S.-based Seagate Technology has said it wants to buy Samsung Electronics Co's loss-making hard disk drive unit for 1.4 billion U.S. dollars -- a deal that will give Seagate access to Samsung's NAND-type flash chips for its solid-state drive products.Western Digital plans to purchase Hitachi Ltd's hard disk drive business for 4.3 billion dollars to give it an edge in developing next-generation storage technology.The two planned acquisitions in a sector with just five manufacturers worldwide have raised concerns in Brussels, the European Commission said."Hard drives are the backbone of the digital economy," said EU competition commissioner Joaquin Almunia in announcing the investigation."The sector has already experienced significant consolidation and the proposed acquisitions will further reduce competition."Brussels officials have until Oct. 10 to decide what action if any they will take.

SAN FRANCISCO, June 17 (Xinhua) -- A new research released on Friday shows that smartphone users in the United States are consuming more data than ever, growing by 89 percent in the first quarter on a year-over-year basis.According to data from marketing company Nielsen, the amount of data the average smartphone user consumes per month is 435 Megabytes (MB) in the first quarter of 2011, compared with 230 MB in the same period last year.As for the distribution of data consumption, data usage for the top 10 percent of smartphone users is up 109 percent while the top 1 percent has grown their usage by 155 percent from 1.8 Gigabytes (GB) in the first quarter of 2010 to over 4.6 GB this year.The research said consumers with iPhones and Android smartphones consume the most data, which is driven by app-friendly operating systems like Apple's iOS and Google's Android. Windows Phone 7 users doubled their usage over the fourth quarter of 2010 and the first quarter of 2011, perhaps due to growth in the number of applications available.Meanwhile, the cost per MB for smartphones has dropped by 46 percent over the last year, from 14 cents per MB to 8 cents, said the research.According to Internet marketing research company comScore, in the first quarter of 2011, 234 million Americans ages 13 and older used mobile devices, 74,6 million of whom are smartphone users.
