WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."

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.

BEIJING, Jan. 23 (Xinhua) -- An online survey has revealed that Chinese people have a mixed opinion on Sunday's Spring Festival TV gala, the 30th of its kind since 1983, albeit many of them agree that there were innovations and improvements in it.As of 10:00 p.m. Monday, about 48 percent of some 71,000 respondents in the poll held by sina.com.cn, one of China's major portal websites, said they think the gala fall short of their expectations.Another 23 percent of them said they think the gala was just fine, and only 10 percent said it was splendid.The gala, an annual grand celebration broadcast by the China Central Television on the eve of the traditional Spring Festival, China's lunar New Year, is the most-watched TV event in the country."I can see the efforts of the gala staff, but it is still not good enough," said netizen "roam the life" at the Sina weibo, a popular Twitter-like microblogging website.At the Sina weibo website, the topic "grumble at the 2012 Spring Festival TV gala" has outnumbered others with over 64 million comments and become the hottest topic of Monday.Nonetheless, many people acknowledge the innovations and improvements in the gala.The gala made some attempts to take a more public-friendly approach by inviting some "grassroots" performers, such as farmer-singer Zhu Zhiwen, as well as cutting all commercials during the broadcast.A dance performance depicting a romance of peacocks and starring Yang Liping, a well-known dancer in China, is the most-followed topic at the gala's official weibo account, drawing over 3,500 comments.The audience was also impressed by a piano duet played by Li Yundi, first prize winner of the the 14th Frederic Chopin international piano competition, and Leehom Wang, a Chinese-American pop singer-songwriter.Moreover, about 59 percent of the online poll respondents said the stage design was quite cool."There are really many improvements in the gala, but it is absolutely difficult to please everyone," wrote weibo user "Wawamiaowaiwai."Unlike their elder generation, the young generation in China has more diversified options for entertainment, and it is of great challenge to attract them at the Spring Festival celebration, said Xia Xueluan, a professor of sociology with Peking University.
