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."

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.

OTTAWA, Oct. 26 (Xinhua) -- Canadians are working about three years longer before retirement than they were in the 1990s, and have a longer life in retirement, an official study said Wednesday.Statistics Canada, the federal statistics agency, reports that Canada' s men and women, who don't face compulsory retirement, are increasingly choosing to delay retirement, as part of a long-term trend that has begun before the recent recession.The trend of later retirement dates back to the mid-1990s, when a 50-year-old employee could expect to work another 12.5 years before retiring from the daily grind.Today, that same 50-year-old worker could expect another 16 years of employment.The study says that 34 percent of Canadians aged 55 and older were employed in 2010, compared to just 22 percent in 1996.A longer working life would unnecessarily imply a shorter life in retirement due to increased life expectancy, the study says.The study notes that men and women leaving the work force today are spending as much time in their post-career life as many of their predecessors did.For example, between 1977 and 1994, the typical retirement length for a man in Canada rose from 11.2 to 15.4 years; as of 2008, it was 15 years.For women, the average retirement length similarly rose from 16.4 to 20.6 years between 1977 and 1996; as of 2008, it was 19 years.From another point of observation, 50-year-old men can expect to spend 48 percent of their remaining years of life in retirement in 2008,compared with 45 percent in 1977.In 2008, 50-year-old women could expect to spend 55 percent of their remaining years of life in retirement, nearly identical to the proportion in 1977.

HELSINKI, Nov. 7 (Xinhua) -- A data leak was uncovered in Finland Saturday, in which personal details of around 16,000 people were uploaded onto a file-sharing website, according to Finnish media report on Monday.This act of sabotage is the largest ever of its kind in Finland. The data leak is being looked into by the Finnish National Bureau of Investigation.Anonymous Finland claimed on Monday responsibility for the publication of personal details of thousands of Finns. The group temporarily published a sample of information on 16,000 people as proof of the hack. The hack was motivated by an apparent desire to shame the Finnish government into improving data security.Finnish National Bureau of Investigation has not confirmed the claims that a loose group of hackers known as Anonymous was behind the data leak.The list that was put on the Internet contains the names, full social security numbers, addresses, telephone numbers, street addresses, and email addresses of the victims. Several upper secondary vocational education institutions are on the list, and some civil servants and students of the Police College of Finland are mentioned by name.Finnish police have confirmed that the names of some Finnish Defense Forces staff are on the list.

NEW DELHI, Jan. 9 (Xinhua) -- Chinese ambassador to India Zhang Yan Monday proposed that China and India make more efforts to develop economic ties.At a meeting on China-India relations attended by Indian National Security Advisor S. Menon, the ambassador said the Chinese side is fully aware of the necessity to narrow the trade gap between the two sides in order to ensure the sustainability of bilateral trade cooperation."China will take measures to increase the import of Indian products which have market demand in China. But our cooperation should not be limited in trade only," said the ambassador.He suggested that China and India should diversify their trade structure, expand the scope and items, and increase the technical content and added value to the products, while expanding into financial, service and investment sectors.The envoy said China and India should initiate policy dialogue and coordinate their economic development strategy in order to ensure steady growth of respective economy, encourage mutual investments, consider the free trade agreement or regional trade arrangement, and increase tourism cooperation.Zhang said that as an encouraging sign of economic ties, the bilateral trade volume is set to hit 70 billion U.S. dollars in 2011, an over 20 percent increase over the previous years, while China set up its first branch of the Industrial and Commercial Bank of China in Mumbai last year.
