BEIJING, Nov. 30 (Xinhuanet) -- Heading football frequently may cause brain damage leading to subtle but serious declines in thinking and coordination skills, a new study suggested as quoted by media reports Wednesday.Researchers used an advanced MRI (Magnetic Resonance Imaging) technique to analyze changes in brain white matter of 32 adult amateur soccer players who head balls 436 times a year on average.The study found players who head football quite frequently -- with 1,000 or more a year -- showed abnormalities similar to traumatic brain injuries suffered in car accidents."This is the first study to look at the effects of heading on the brain using sophisticated diffusion tensor imaging," said Dr. Michael Lipton, a leading researcher and associate director of the Gruss Magnetic Resonance Research Center at the Albert Einstein College of Medicine in New York City."We found the real implication for players isn't from hitting headers once in a while, but repetitively, which can lead to degeneration of brain cells," he added.The researchers compared neurological images of study participants, whose average age was 31, and found those with the highest volume of headers had abnormalities in five areas of the brain, responsible for attention, memory, physical mobility and high-level visual functions.The findings come in the wake of mixed reports on the so-called "cognitive" consequences of frequently heading soccer balls at practice.Dr. Chris Koutures, a pediatrician and sports medicine specialist in Anaheim Hills, California, said the retrospective imaging study was fascinating, but needs more data to effectively determine safe header limits, especially for younger players.Dr. Lipton agreed neuropsychological damage from headers would be hard for a coach or physician to notice since cognitive problems develop gradually, and even players might not be aware of mild memory loss."We can't tell an individual today not to be heading a ball, but caution is a good thing," Lipton said. "We need more research for definitive answers and we have the advanced imaging tools to do it."

BEIJING, Sept. 30 (Xinhuanet) -- China's space dream took a step closer to reality as the Tiangong-1 module blasted off into the night sky on Thursday from the Gobi Desert.The Long March II-F T1 rocket, under the unmanned module, Tiangong-1, lifted off from the Jiuquan Satellite Launch Center at 9:16 pm as planned.Ten minutes later Tiangong-1 separated from the rocket on its way to orbit, 350 kilometers above Earth. The module deployed its two solar panels, which provide power, at 9:28 pm.At 9:39 pm, Chang Wanquan, chief commander of the manned space program, declared the launch a success as cheers and applause echoed around the command and control center in Beijing.President Hu Jintao and other members of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee went to the center to witness the launch.Premier Wen Jiabao watched at the Jiuquan Satellite Launch Center as the Long March rocket, carrying the space lab, blazed into the night sky.The launch paves the way for China's first rendezvous and docking mission. An unmanned Shenzhou VIII spaceship will be launched in November to dock with Tiangong-1.Two more missions are scheduled for next year and astronauts will board Tiangong-1, which can also function as a space lab.If the mission succeeds, China will become the third country to master spacecraft rendezvous and docking technology following the then Soviet Union and the United States, experts said.Wu Ping, the space program's spokeswoman, said that the ability to rendezvous and dock is vital for building a space station, which China has scheduled for around 2020."A space station cannot be launched in one shot. The modules must be launched separately and then assembled in space," she said.China has invested 35 billion yuan (.47 billion) in total on its manned space program since 1992, when it was approved, she told China Daily.The first phase, from 1992 to 2005, accounted for 20 billion yuan. During this period, China launched six Shenzhou spaceships to set up a system transporting astronauts between Earth and space.In the second phase, from 2005, 15 billion yuan has been spent on projects, including Shenzhou VII and the first rendezvous and docking mission, she explained.Zhou Jianping, chief designer of China's manned space program, said that the space lab and future space station provide a rare platform for conducting experiments that could lead to breakthroughs in the study of materials and biological pharmacy."Experiments made in the microgravity of space can lead to unexpected results," he said.For example, gas and liquid are unable to mix on Earth, but in space they mix naturally, he said."The primary purpose of China's manned space station is to peacefully explore space, and through it, serve mankind," he said.Some have questioned the participation of the military in the program. However, the military has experience in coordinating large-scale requirements that are vital for the program and their involvement reflects international norms, Ministry of National Defense spokesman Geng Yansheng said on Wednesday.He reiterated that China is firmly opposed to the weaponization of space and the program is peaceful.China is now in the second phase of its manned space program. The goal of the program, which has three steps, is to build a 60-ton space station around 2020.The second phase focuses on mastering four key technologies for assembling a space station.The first of these, extravehicular activity, was completed successfully in 2008 after Shenzhou VII was launched.Rendezvous and docking is what is being experimented with. The third technology involves cargo spaceships ferrying supplies to a space lab. The fourth tackles problems concerning the prolonged sustaining of life on a space lab, especially recycling air and water.Besides the manned space program, China launched two lunar orbiters in 2007 and 2010. It plans an unmanned lunar landing around 2013, and returning moon samples in 2017.

COTABATO, Philippines, Jan. 2 (Xinhua) -- The health authorities declared an outbreak of a deadly rat fever on Monday in the flood-hit areas in the southern Philippines.At least five people were already dead and as many as 200 were diagnosed in the southern city of Cagayan de Oro with leptospirosis, a fatal animal-borne disease that can result in high fever, internal bleeding and organ failure.The latest fatality, an old woman, died late Monday due to complication.Dr. Jaime Bernadas, regional health minister, said they fear the number of patients displaced by typhoon Washi could increase in the coming days.Congressman Rufus Rodriguez has called on people affected by the floods that killed over 1,200 people to avail of the government's vaccination against the deadly disease.The death toll from tropical storm Washi currently stands at 1, 258 people with many still believed missing. Washi brought massive rains, causing flooding in many areas in the Central and Southern Philippines starting last Dec. 16.

BEIJING, Dec. 23 (Xinhua) -- The personal information of more than 6 million Internet users on CSDN, or China Software Developer Network, the country's largest programmers' website, was leaked by hackers, raising concerns about web security and triggering widespread panic.The leak was first exposed by China's leading anti-virus software provider, Beijing-based Qihoo 360, on Wednesday. The company said the leak included user IDs, passwords and e-mail addresses in clear text.The hacking case escalated on Thursday after the personal details of subscribers to more websites, including popular online gaming and social networking sites, were leaked.Online media reports said the personal data of up to 50 million Internet users has been leaked so far, but the number could not be independently verified.In response, the National Computer Network Emergency Response Technical Team/Coordination Center of China (CNCERT/CC) issued a statement Thursday, saying the CSDN's user data bank that leaked on the Internet was created before April 2009 and the passwords were stored in clear text, but the passwords had been encrypted after the data bank was upgraded in April 2009."Therefore, similar security problems have not been found in the newest user data bank," the statement said.Technical experts are investigating how many websites and users were actually involved in the hacking case, said Zhou Yonglin, director of the CNCERT/CC Operating Department."False information and exaggerations cannot be ruled out," he said.Nevertheless, CNCERT/CC has ordered CSDN to take immediate action in repairing the system hazards and providing users with timely security solutions.Computer security experts at Qihoo 360 believe the leak has spread to other websites."Many Internet users have registered the same passwords for their e-mail, microblog, online gaming and online payment accounts, so, if the server of one of the websites is hacked, their accounts and passwords on other websites would also be stolen," said Qihoo 360's Dr. Shi Xiaohong.Police authorities in Beijing told Xinhua on Friday that an investigation has been launched.WEB SECURITY IN QUESTIONDisgruntled Internet users in China rushed to change their passwords after the leak occurred, the largest of its kind in the history of China's Internet development."It is very annoying. I had to spend almost an hour changing the passwords of all my online accounts, especially those for payment accounts," said Li Xing, a white-collar worker at a technical company in Beijing.

BEIJING, Nov. 5 (Xinhua) -- China said Saturday that positive and balanced outcomes were achieved at the sixth summit of the Group of Twenty (G20) held earlier this week in the southern French city of Cannes."All the sides were committed at the summit to further coordinating their macro-economic policies, stabilizing the financial market, prompting economic growth, improving global economic governance and working together to maintain the hard-won momentum of the economic recovery," said Ma Zhaoxu, spokesman of the Chinese delegation after President Hu Jintao returned from Cannes, where Hu and the leaders of other G20 members' met to tackle major issues affecting global economic recovery and financial stability.The Chinese spokesman mentioned the Declaration, the Communique and the Action Plan issued after the meeting as "three outcome documents" of the G20 Cannes summit.Ma said priority was given to the European sovereign debt issue at the meeting."All the sides noted that the European Union has recently put forward a new series of measures and ideas to address the sovereign debt issue and hope that these measures will help Europe to stabilize the financial market, overcome the current difficulties and spur the economic recovery and development," he said.The Cannes Action Plan approved at the summit was meant to coordinate the macro-economic policies of all the members to endorse economic recovery and summon market confidence, said the spokesman.
