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, Nov. 4 (Xinhuanet) -- The amount of trans fat and other nutritional information will be marked on the labels of prepackaged food, according to the country's first national standard for food nutrition. The labeling will take effect on Jan 1, 2013. "It will help standardize the nutrition facts labeling by food producers and facilitate consumers' rights to know and choose, while improving public awareness of food nutrition," said Yang Yuexin, a senior nutritionist with the Chinese Center for Disease Control and Prevention (CDC). The new regulation by the Ministry of Health stipulates that food labels have to include the food's nutrition information, including levels of energy, protein, fat, carbohydrate and sodium. Food products without proper labels showing the nutritional information will be banned when the new rule takes effect. The new regulation also stipulates that if any hydrogenated or partially hydrogenated fat is used to produce the food, the level of trans fat will have to be highlighted on the nutrition information label. Trans fat is usually produced during food processing when liquid oils are converted into semi-solid fats that help keep food fresh longer. However, the partially hydrogenated oil contains trans fat that can substantially increase the risk of heart disease. However, Zhang Jian, a researcher with CDC's National Institute for Nutrition and Food Safety, said that compared to Western diets, the Chinese diet contains a far lower level of trans fat and there is no need to over react.

SAN FRANCISCO, Nov. 3 (Xinhua) -- Computer chipmaker Advanced Micro Devices Inc. (AMD) on Thursday said it plans to cut its global workforce by about 10 percent in a move to reduce operational costs.The layoff will occur across all functions globally and is expected to be substantially completed by the end of the first quarter of 2012, the company said.The cuts will amount to about 1,400 jobs, according to estimates by analysts.Combined with implementing efficiencies across the company's operations, AMD expected that the workforce reduction will result in operational savings of more than 200 million U.S. dollars in 2012."Reducing our cost structure and focusing our global workforce on key growth opportunities will strengthen AMD's competitiveness and allow us to aggressively pursue a balanced set of strategic activities designed to accelerate future growth," Rory Read, AMD's chief executive officer, said in a statement.As the world's second largest maker of processors for computers, AMD has been suffering from the slowdown of global PC market and is seen as slow to move into new mobile device market.The operational savings will help accelerate the company's future growth in lower power, emerging markets and in the cloud computing field, AMD said.

SAN FRANCISCO, Nov. 11 (Xinhua) -- Apple on Friday said it will "continue to investigate" the unexpected iPhone battery drain as some users still see the problems after downloading a latest software update designed to address the issues."The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues," said Apple in a statement made to technology news site AllThingsD.Apple released iOS 5.0.1, an update to its latest mobile operating system iOS 5 on Thursday. The update includes fixes for some bugs which are blamed for shortening the battery life of iPhones and other devices that use the system.Some users said the battery life of their iPhones look much better after the update. But according to some posts on Apple's official support forums, some iPhone owners still claimed the issue is persisting, saying they saw no difference at all after downloading the update.Complaints about the battery life of Apple's latest iPhone 4S smartphone have been piling up on the Internet in the past weeks.On Apple's official support forums, some iPhone 4S owners said their handsets' battery drained more than 10 percent every hour, even when in standby mode with some advanced features like Siri and location services completely deactivated.It is reported that Apple engineers contacted some iPhone 4S owners in Britain and installed a diagnosis file on their devices to send details back to the company's headquarters in Cupertino, California.Apple confirmed the iPhone battery issue last Wednesday, saying that a few bugs in the iOS system have caused the problem and it will release a software update in a few weeks.
