BEIJING, Feb. 28 (Xinhua) -- Construction began on China's first low-speed maglev line Monday in Beijing, a project that will make China only the second country with a low-speed maglev line after Japan.The project marked China's ability to industrialize low-speed maglev technologies, said Chang Wensen, father of China's maglev technology and professor at the National University of Defense Technology.The 10-kilometer line runs from Shimenying Station in west Beijing's Mentougou District to Pingguoyuan Station in the Shijingshan District.The line, a section of Line S1 on the Beijing subway network, is expected to be completed in 2013 with a designed speed of 100 to 120 km per hour.China's research of maglev technologies was started in the 1980s by a team led by Chang Wensen. A 204-meter test line in central China's Hunan Province and a 1.5-km test line in north China's Hebei Province were built jointly by Beijing Maglev Technology Development Co., Ltd. and National University of Defense Technology.The intensity of the magnetic field had been tested as safe, according to a test report of Institute of Electrical Engineering, Chinese Academy of Sciences.The cost of the low-speed maglev line was estimated at 300 million yuan (4.6 million U.S. dollars) per kilometer, slightly more than light rail, but cheaper than the subway, which cost more than 600 million yuan a kilometer, said Li Jie, director of technology research center of National University of Defense Technology.The technology was also under consideration for Line 8 of the subway network in Shenzhen, in south China's Guangdong Province, said Liu Zhiming, board chairman of Beijing Maglev Technology Development Co., Ltd.."If Shenzhen adopts the technology, Line 8 will be China's second low-speed maglev line," he said.The world's first low-speed maglev line, at 8.9 km long, was completed in Japan in March 2005.Maglev, short for magnetic levitation, technology uses a large number of magnets to lift and propel a vehicle, making it faster, quieter and smoother than conventional wheeled transport systems.High-speed maglev vehicles can reach speeds of 450 km per hour and are usually used in long distance transportation, while low-speed maglev lines are usually used in short distance transportation.Construction also began on another seven lines on the Beijing subway network Monday.With an investment of 82 billion yuan (12 billion U.S. dollars), the eight lines will total 113.7 km in length and are expected to open from 2013 to 2015.Beijing has 16 lines under construction.

SHANGHAI, March 17 (Xinhua) -- Lenovo Group and a subsidiary of Shanghai Media Group (SMG) signed an agreement on Thursday to create a firm that would provide mobile-Internet video services.BesTV New Media Co., a subsidiary of SMG, owns 51 percent of the venture, named Shanghai Video Cloud Company Limited, while Lenovo owns the remainder. The total investment of both parties in the new firm exceeded 10 million yuan (1.52 million U.S. dollars), according to the agreement.Lenovo is currently the largest personal computer maker in China. BesTV New Media is a provider of Internet Protocol Television (IPTV), mobile television and other forms of new media. 

BEIJING, Feb. 2 (Xinhua) -- From dumplings in the north and rice cakes in the south, people across China Wednesday overloaded their tables with holiday foods, cheering for the Spring Festival family reunion and praying for a better life in the coming Year of Rabbit.In a remote village in Guizhou Province, villagers were sharing millet cakes and preserved pork as sunshine dispelled cold and sleet, which have plagued China's southwest for a month."This year's Spring Festival is especially cheerful, since our dream of a new home has come true," said villager Zhang Jiuyun.Zhang's home was severely damaged in the snow and sleet disaster, but with the help of local villagers and funds from the government, Zhang built a larger house without spending much money.The Spring Festival is also an important occasion for migrant workers to enjoy family reunions after toiling for higher incomes in wealthy coastal provinces for a year."I've brought back red wine and cookies imported from Italy as gifts for my parents," said Ding Zhenghe, a Shenzhen-based factory owner who has worked his way up from a migrant worker.But Ding said, after years in the modern city, he still yearns for the the food cooked by his mother in the rural home.The Spring Festival, which falls on Thursday, also marks the start of the Year of the Rabbit. It is a time for family dinners, gift giving and fireworks.Nangkun Tashi, a villager in the earthquake-hit Yushu, northwest China's Qinghai Province, celebrated the first Lunar New Year after the disaster with traditional Tibetan food, such as mutton and butter tea.A 7.1-magnitude earthquake jolted Yushu in April 2010, killing about 2,200 people and leaving Tashi's village in ruins.Tashi's family narrowly survived the quake, and have recently moved into a new home, which was provided by the local government two months before.In Zhouqu County, Gansu Province, 990 tons of grains have been delivered to the 473 survivors, who now lived in temporary housing after a massive landslide leveled the county, leaving over 1,500 people dead in August."We are able to hold a celebration, even though we've lost everything in the landslide," said local resident Yao Shelin."We've received flour, cooking oil, and even the wok is a donation," said Yao.

BEIJING, May 24 (Xinhuanet) -- Scientists revealed for the first time the molecular structure of proteins, which enables bacteria to transfer electrical charges, according to a new study. The revelation was published in Proceedings of the National Academy of Sciences in the U.S. on Monday.Scientists used a technique called "x-ray crystallography" to reveal the molecular structure of proteins, which work as atom-sized "wires" discharging excess electricity."This is an exciting advance in our understanding of how some bacterial species move electrons from the inside to the outside of a cell," said lead author Tom Clarke of the University of East Anglia's School of Biological Sciences in Norwich, England.He said this discovery means "We can now start developing efficient 'bio-batteries' as the viable energy source in the future."Still, it could take perhaps a decade to go. Before that, existing uses of such bacteria needed to become 100 or 1,000 times more efficient, he said.The advance could also hasten the development of microbe technology that can help clean up oil or uranium pollution, he said.Microbes might in future be enlisted to clean up nuclear accidents such as Japan's Fukushima Daiichi disaster, he added.

WASHINGTON, March 24 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Thursday approved the use of Zostavax, a live attenuated virus vaccine, for the prevention of shingles in individuals 50 to 59 years of age. Zostavax is already approved for use in individuals 60 years of age and older.In the United States shingles affects approximately 200,000 healthy people between the ages of 50 and 59, per year. It is a disease caused by the varicella-zoster virus, which is a virus in the herpes family and the same virus that causes chickenpox.After an attack of chickenpox, the virus lies dormant in certain nerves in the body. For reasons that are not fully understood, the virus can reappear in the form of shingles, more commonly in people with weakened immune systems and with aging."The likelihood of shingles increases with age. The availability of Zostavax to a younger age group provides an additional opportunity to prevent this often painful and debilitating disease" said Karen Midthun, director of FDA's Center for Biologics Evaluation and Research, in a statement. ( Shingles is characterized by a rash of blisters, which generally develop in a band on one side of the body and can cause severe pain that may last for weeks, and in some people, for months or years after the episode.Approval was based on a multicenter study conducted in the United States and four other countries in approximately 22,000 people who were 50-59 years of age. Half received Zostavax and half received a placebo. Study participants were then monitored for at least one year to see if they developed shingles. Compared with placebo, Zostavax reduced the risk of developing shingles by approximately 70 percent.The most common side effects observed in the study were redness, pain and swelling at the site of injection, and headache, according to the FDA.Zostavax, manufactured by Merck & Co., was originally approved on May 26, 2006, for the prevention of shingles in individuals 60 years of age and older.
