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, Dec. 13 (Xinhua) -- Apple is in talks to acquire Israeli fabless semiconductor maker Anobit for 400 million to 500 million U.S. dollars, U.S. media reported on Tuesday.Apple is likely interested in Herzliya Pituach, Israel-based Anobit for an exclusive access to its embedded flash controllers which can significantly boost memory performance of smartphones and tablet computers, said technology news site TechCrunch, citing Calcalist, an Israeli newspaper in Hebrew which first reported the possible acquisition.Apple already uses Anobit's technology in iPhone, iPad and the MacBook Air.If the deal works out, it could be Apple's largest acquisition ever, surpassing its 404 million-dollar purchase of NeXT in 1997.It could also become Apple's first acquisition in Israel and the first with Tim Cook as the chief executive officer of the company since its iconic leader Steve Jobs passed away in early October.

  

NANJING, Dec. 8 (Xinhua) -- Chinese stargazers will have their best view of a total lunar eclipse in 10 years on Saturday if weather permits, the Zijinshan Astronomical Observatory under the Chinese Academy of Sciences (CAS) said Thursday.Wang Sichao, a research fellow with the observatory, said during the total eclipse, the full moon will not completely disappear from the Earth's shadow, but will take on a brilliant bronze color.He said the eclipse will be the best one seen in China since the last one occurred on Jan. 10, 2001."Theoretically, viewers can observe the eclipse from nearly everywhere in the country on Saturday," said the astronomer.He said the eclipse, the second this year, will last for 51 minutes. It will start at 8:45 p.m. and reach its climax at 10:06 p.m.Wang said Chinese viewers will have to wait until Oct. 8, 2014 to see the next total lunar eclipse.

We will aim to deepen the mutually beneficial relationship based on common strategic interests," Gemba said Tuesday in his first foreign policy speech in parliament.He went on to say that Japan plans to proactively make " concrete efforts" to strengthen its ties with China and establish more "open and multilayered networks" in the best interests of both countries.
