BEIJING, April 12 (Xinhuanet) -- The elderly have a difficult time with multi-tasking as a study suggests that older brains behave differently when it comes to switching between two tasks, according to media reports on Tuesday.Researchers used functional magnetic resonance imaging (FMRI) to analyze brain activity in 20 people over age 60 by asking them to contemplate outdoor photos shown briefly. Then the elderly were presented with the picture of a face and asked to determine its gender and age, before being asked to recall details from the original scene they viewed.Researchers then compared their results to a similar experiment with 20 younger adults and found the brains of older subjects were less capable of disengaging from the interruption and reestablishing the neural connections necessary to switch back to focusing on the original memory."Unlike younger individuals, older adults failed to both disengage from the interruption and re-establish functional connections associated with the disrupted memory network," write Wesley C. Clapp of the University of California, San Francisco, and colleagues in the Proceedings of the National Academy of Sciences.The study, published in the online edition of the journal Proceedings of the National Academy of Sciences, sheds new lights into a growing body of studies showing that one's ability to move from one task to another in quick succession becomes more difficult with age.

BEIJING, Feb. 5 (Xinhua) - Beijing has seen the arrival of 660,000 tourists during the first three days of the Spring Festival holiday, from Feb. 2 to 4, said Beijing Municipal Bureau of Tourism officials late Friday.The tourism data was collected at the city' s 22 scenic spots.On February 4, official statistics showed that 40,000 tourists swarmed into the Palace Museum, repeating the number from last year' s national holiday, while about 14,500 ski-lovers enjoyed their time at 14 ski resorts in Beijing on the same day.Not only scenic spots, tourists also gravitated to some cultural venues in Beijing.The Beijing-based National Art Museum of China holds an exhibition on "donated masterpieces over the past 50 years (since its completion in 1952)" from Jan. 27 to Feb. 26 and spectators can visit, free of charge, during the Spring Festival holiday (between Feb. 3 and 9).On February 5, visitors queued up in a 200-meter long line waiting for check-in to the museum around 10 a.m.Wang Xiumei, 86, decided to visit the museum with her daughter ten days before."My husband and I were crazy about traditional Chinese paintings decades ago, I have to see some masterpieces today, rather than hearing about them later." Wang said.Hundreds of the nation' s art works are displayed in a dozen halls in the five-storey exhibition area, including oil paintings, ink paintings, wood block prints, shadow puppets, paper cuttings, clay sculptures and embroideries."I changed my mind and got off the bus on my way to a temple fair. My children and I want to see some elegant art works, as opposed to eating and playing during Spring Festival as before," said another citizen named Lu Hongmao.Big cities like Beijing, Shanghai and Guangzhou opened their sports venues to the public during the Spring Festival holiday.

BEIJING, Feb. 18 (Xinhua) -- China needs to reform funding methods for scientific and technological research in order to boost the nation's innovation capabilities, said officials and researchers attending a conference in Beijing Friday.The management of the government-funded research projects should also be reformed, State Councilor Liu Yandong said at the national conference on science and technology work.Liu stressed that reform, innovation and cooperation should be the keys for China's science and technology work over the next five years, when the government would increase funding for research in new strategic industries, such as new energy, biomedicine and high-end manufacturing.Last year, central and local government spending on science and technology development totaled 380 billion yuan (57.8 billion U.S. dollars), Science and Technology Minister Wan Gang said at the conference.Over the past five years, central government spending on science and technology development had grown by around 20 percent annually.However, some researchers have complained problems in the funding system actually hinder innovation and progress.Inflexibility in the management of government funds allowed researchers little freedom to adapt projects to developments in their fields, said Li Zhenzhen, a researcher at the Institute of Policy and Management under the Chinese Academy of Sciences (CAS).Chen Jie, a research fellow of the CAS' Institute of Microelectronics, said some authorities which oversee the spending of research funds had been rather rigid."In some cases, they are more interested in spending most of the funds on new equipment than scientists," Chen said in an earlier interview with Xinhua. "Without decent pay, it is difficult to attract top scientists to work in China.""Having to solicit and lobby for funding to support the team's research projects leaves me no more than five hours a day for real research," Chen said.Top-level scientific brains are the key to the innovative capability of China, he added.A researcher attending Friday's conference echoed Chen's opinion."China manufactures 65 percent of the world's computers. But to my knowledge, we are still spending about 150 billion U.S. dollars annually to buy computer chips from overseas," the researcher told Xinhua on condition of anonymity.Wan Gang also said imported computer chips cost China more than crude oil purchases last year.But Wan believed that with breakthroughs in frontier areas such as cloning, manned space flight, moon exploration and supercomputers, China could expect a leap in science and technology development in the near future.In October last year, China successfully launched its second lunar probe, Chang'e-2.A month later, Chinese supercomputer Tianhe-1A, which can perform 2.57 quadrillion computing operations a second, was ranked the world's fastest in the TOP500 list compiled by U.S. and European researchers.

BEIJING, Feb. 14 (Xinhua) -- "Dear Premier Wen, I'd like to tell you the good news first. The problem I brought up at the seminar last year has been solved in Beijing," wrote 34-year-old, wheelchair-bound Li Nan to Chinese Premier Wen Jiabao on Jan. 20 this year.The problem Li referred to was the high prices of one-off hygiene products that had plagued people with work-related spinal cord injuries for a long time.On Jan. 31, 2010, Wen talked with a group of ordinary people in Chaoyang District in Beijing to get their opinions on the draft of a government work report that will be submitted to the national legislature in March.Wen asked Li to be the first to voice her views at the seminar. Li said that patients with spinal cord injuries had to spend about 2,000 yuan (303 U.S. dollars) a month on one-off hygiene products because of their incontinence."My injury allowance is roughly 2,000 yuan a month. I have to live on my parents' pension," she said.She suggested giving more attention to the employment and mental health of the disabled, and also for some revisions on the catalogue of drug and auxiliary devices for those disabled by work-related injuries. She also proposed more subsidies for these people.Responding to the suggestions, Wen said, "Li Nan's case is far from an individual one. The disabled are a very large group of people in China who need more attention... We need to study, revise and renew the government regulations on work-related injury insurance."Wen also encouraged Li to be optimistic in face of ordeals.Li, who graduated from Beijing Youth Politics College in 1997, was once a prize-winning amateur dancer. However, she became confined to a wheelchair after a traffic accident in 2003.On March 5 last year, Li beamed with pride as she watched TV. Premier Wen was delivering the government work report at the annual session of the national legislature.Wen pledged to "work harder to build the social security and social services system for people with disabilities." The premier also promised that "Workers' compensation will be extended to all of the 1.3 million workers injured in previous jobs who are not receiving benefits.""I am thrilled to see that my advice on improving social security for the disabled was included in the government work report," Li said in her letter, which summarized the changes she experienced in the past year because of the improved social security system.The Beijing Municipal Human Resources and Social Security Bureau announced last year that people would be reimbursed for one-off diapers and urine bags under the municipal work-related injury insurance program beginning June 2010."The Beijing policy has relieved our heavy economic burdens and ensured the quality of our life," Li wrote.Li, however, said that though some places has begun to give living and nursing subsidies for the disabled, the policy needs to be extended to other parts of the country.After reading the letter on Jan. 31, Wen Jiabao instructed relevant organs in the State Council, or Cabinet, and the Beijing municipal government "to conduct research and set down policies to better protect and aid people with serious disabilities, and to help them solve their difficulties and improve their quality of life."

HARBIN, March 2 (Xinhua) -- A therapeutic apparatus to treat Parkinson's disease has been developed in northeast China's Heilongjiang Province, according to the provincial science and technology department. It is a worldwide breakthrough in treating the disease with transcranial magnetic stimulation, concluded an expert panel with the Heilongjiang Provincial Department of Science and Technology.The team said it came to the conclusion after evaluating technical documents and clinical test results Monday.This is the first time that transcranial magnetic stimulation has been adopted to treat Parkinson's disease, said Sun Zuodong, chairman of Aobo Medicine Apparatus Co., Ltd. (AMA), the developer based in the provincial capital Harbin.Transcranial magnetic stimulation is a noninvasive method which causes depolarization in the brains' neurons so as to restore the functions of brain nerves.The apparatus consists of three parts, namely brain wave stimulator, field effect cap and multiplier, said Sun.Clinical tests over more than 100 patients showed that the apparatus had a 70 percent success rate in reducing the disease's symptoms, according to Wang Aili, planning manager of AMA.The new equipment will help generation of dopamine, the reduction of which within the brain caused the disease, said Wang Weixiang, a consulting doctor with the Heilongjiang Provincial Rehabilitation Hospital.Parkinson's disease is a disorder of the neural system, which leads to limb tremors and difficulty in walking and other movements.China has 2 million patients suffering from Parkinson's disease, mostly people over the age of 50, and the number is increasing by 100,000 annually, said Dr. Wang.
