JERUSALEM, Nov. 1 (Xinhua) -- Israeli researchers at Tel Aviv University developed a computer chip that could recuperate loss body movement if placed in the cerebellum, opening the doors to treatment of brain damage, researchers told Xinhua on Tuesday.The computer chip, wired to a man-made segment of a cerebellum, was attached to a rodent's skull that had lost the ability to blink. After the artificial cerebellum was implanted, the rodent was once again able to blink.The chip, connected to the rat's brain, works by reading sensory information from the body and then communicating it to the cerebellum, the area of the brain that allows movement coordination, through electrodes."The chip itself imitates a small part of the cerebellum, a very tiny part of it," said Prof. Matti Mintz of TAU's Department of Psychology."We took a small part of the cerebellum and studied it and created the computer chip that mimics the damaged area," he said.However, more complicated movements, like walking, are still at least one decade away, Mintz added."We still did not test it on humans because we need to know the area the chip will mimic before installing it, which requires extensive research. But we are now developing a chip that will do a sequence of simple movements," he pointed out.When fully developed for humans, it can be used to help patients who suffer brain genetic diseases like Parkinson, or had strokes that caused brain damage.

BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.

NEW YORK, Dec. 1 (Xinhua) -- New York City Mayor Michael Bloomberg announced on Thursday a new recommendation that doctors offer every person with an HIV diagnosis antiretroviral treatment to help them live longer and prevent transmission.This marks a change from the current practice that treatment only be offered to those who show signs of damage to their immune systems, said the mayor during the annual World AIDS Day commemorative ceremony at Gracie Mansion. "Over the past ten years HIV diagnoses and deaths in New York City have seen a dramatic decline," said Mayor Bloomberg. "Steady progress in our fight against HIV has turned what used to be a death sentence into a disease that can be prevented and, with antiretroviral therapy, managed.The annual death toll from HIV in the city is down by more than a third: 933 deaths in 2009Despite this progress, however, more than 110,000 people in New York City are infected with HIV, more than in any other U.S. city and about 75 percent of all cases in the New York State.Figures from the New York City Health and Hospitals Corporation (HHC) showed that HHC has tested more than one million New Yorkers for HIV since 2005 when the public hospitals and health centers began offering HIV screening as a routine part of medical care for patients aged 13 to 64.

BEIJING, Dec. 12 (Xinhuanet) -- For many multinational firms, the past 10 years in China have not only marked the rise of the world's second-largest economy but have also been a decade of expansion and profit growth.As they look back at this "golden decade", which is often used to describe the days after China entered the World Trade Organization (WTO) in 2001, their early expectations and ambitions in a more liberalized Chinese market were found to be more than fulfilled.When German auto giant BMW set foot on the Chinese mainland by establishing its first office in Beijing in 1994, its products were still far too luxurious for ordinary Chinese.In 2001, only 6,500 vehicles were sold under the BMW and Mini brands in China.NYK Diana, a container ship, anchors at Qingdao Port in East China's Shandong province on Thursday, as workers load cargo.But sales started to pick up with China's WTO entry, when the removal of trade barriers brought unprecedented economic growth and a booming market.In 2010, the vehicle maker, which started a joint venture with the domestic Brilliance China Automotive in 2003, sold 169,000 vehicles in China.That record is set to be broken this year as more than 170,000 cars were sold only in the first three quarters."We are both beneficiaries and firm supporters of the open market system," said Christoph Stark, president and CEO of BMW's Greater China region.By liberalizing its market, China, which celebrated the 10th anniversary of its WTO accession on Sunday, has become a thriving market and a savior for foreign enterprises hit hard by the global downturn.In 2009, when General Motors declared bankruptcy in the United States amid the global recession, its Chinese branch saw sales rise 66.9 percent year-on-year to more than 1.8 million units.In 2010, China overtook the United States to become GM's largest national market.The list of similar companies is extensive, as China's decade-long membership of the WTO has helped the Asian powerhouse attract 347,000 foreign firms with investment of more than 0 billion in the past 10 years.Chong Quan, deputy representative for China's international trade talks, said foreign enterprises made more than 0 billion in profit in the 10-year period, with an average annual increase of 30 percent."The accession to the WTO has made China a more transparent, safe and predictable market, as well as an essential part of the global economy," said Dominique Poulique, president of Alstom China.The French power engineering and train company, with more than 30 entities and about 10,000 employees in China, is one of the major foreign suppliers to the Chinese rail transport market."Rapid changes took place in China in the past decade, with its massive investment in infrastructure construction and notable development in energy," Poulique said.Wang Zhile, director of the research center of transnational cooperation under the Ministry of Commerce, said increasing shared interests between China and multinationals are putting them into an inseparable community, one that has found win-win solutions in the past decade.There is also high-quality labor at a relatively low cost, including white-collar workers, he added.Admittedly, the huge market and rich resources have powered up multinational firms in global competition, especially during and after the financial crisis.Forty-nine percent of the responding multinational companies had higher expectations for China in the wake of the global financial crisis in 2008 and 2009, according to a recent survey by the Economist Intelligence Unit, a business information arm of the Economist Group.Although showing signs of a slowdown, China's economy is still widely expected to grow by more than 8 percent next year, at a time when debt and financial instability are weakening growth in other leading economies.Poulique said he expected China's rapid growth to continue into the next decade, especially in the infrastructure construction market."For Alstom, the top task here is to keep adapting to the changing business environment," he said.Many foreign companies are moving research and development facilities to China in the hopes of making it a base for talent and technology.In Shanghai, 347 multinationals have set up regional headquarters, with the establishment of 333 foreign-funded research and development centers.
