MOSCOW, Nov. 25 (Xinhua) -- Russia's Proton-M carrier rocket was launched on Friday from the Baikonur space center in Kazakhstan with a Chinese communications satellite "AsiaSat-7", according to Russia's Federal Space Agency Roscosmos.Roscosmos' live broadcast on its official website showed that the Proton-M rocket atop the Briz-M upper stage was launched at 23: 10 Moscow time (1910 GMT). The separation of the satellite from the rocket was scheduled for 08:23 Moscow time (0423 GMT) on Saturday.The AsiaSat-7 which belongs to the Asia Satellite Telecommunications Company Limited (AsiaSat) located in Hong Kong, China, is a new generation satellite designed to replace AsiaSat 3S at the orbital location of 105.5 degrees East.The new satellite was expected to support a broad range of applications for the Asia-Pacific region, including television broadcast and VSAT (Very Small Aperture Terminal) networks.

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."

BEIJING, Jan. 9 (Xinhua) -- China's official website for booking train tickets received a daily average of more than 1 billion hits during the first week of January, according to a railway official.Hu Yadong, vice minister of railways, said Sunday that the online ticket sales platform has provided consumers with a convenient way to buy tickets. He also addressed complaints about the fairness of the sales process."Train tickets sold online or by telephone have topped 2 million daily, meaning that around one-third of passengers don't have to wait in line at train stations for several hours to get a ticket," Hu said.However, many Chinese have expressed dissatisfaction with the website, with some people unable to get train tickets home for this year's Spring Festival holiday, a major holiday in China.Several customers posted their complaints on popular microblogging website weibo.com, stating that the booking site often failed due to "too many visits at the same time."The Spring Festival holiday is always a difficult time for China's public transportation authorities. A total of 3.16 billion passenger trips are expected during the holiday, up 9.1 percent from a year earlier, of which 235 million trips will be made via the country's railways, up 6.1 percent year-on-year, said Hu.This year's transport rush in the Spring Festival Season started on Sunday and will end on Feb. 16, according to the Ministry of Railways.

BEIJING, Oct. 20 (Xinhuanet) -- A Teenager's intelligence is not fixed as usually thought. Instead, it can go through swings in a few years, according to a British study reported online in Nature.Teenagers' IQ can rise or fall 20 points over time, researchers from Wellcome Trust Centre for Neuroimaging of Kings College, showed in their study.IQ (short for "intelligent quotient") is an gauge of mental capability measured through a series of standardized tests of language skill, spatial ability, arithmetic, memory and reasoning.To get the findings, Cathy Price, senior researcher of the study, and her colleagues tested 33 British teenagers between the ages of 12 to 16 in 2004, who had average IQ scores around 100. Then the teenagers were retested four years later.The researchers found the volunteers' IQ scores went up and down over the four years, with some teenager's scores rising by as many as 20 points, and others' dropping by the same points."That is quite astounding," cheered psychologist Robert Plomin from the same university but not involved in the study. Dr. Price and her colleagues don't know the causes of such fluctuations in the scores they tested, but speculate that learning experiences might account the changes, reported by the Wall Street Journal Today. "We have to be careful not to write off poorer performers at an early stage when in fact their IQ may improve significantly given a few more years," stated Dr. Price cited by the Huffington Post.
