SHANGHAI, May, 13 (Xinhua) -- Scientists attending a recent high-level conference on robotics agreed that great progress has been made in the field, but strict rules for the safe usage of robots should be implemented."Four years ago, if you went into a Chinese factory and said 'robots can help you work,' you would be kicked out. But now, China has a large industrial robot market, along with Japan, the Republic of Korea and the United States," says Li Zexiang, general chair of the 2011 International Conference on Robotics and Automation (ICRA 2011), which concluded Friday in Shanghai.Chinese robotics researchers have suggested to the government that rules and regulations for robot usage should be created. Professor Wang Tianmiao from the Beihang University (BUAA) told Xinhua about the suggestions during the conference.Wang says that in the future, it might not be possible for artificial intelligence to take the place of humans in some social roles. However, Wang says that mankind should pay close attention to the possible dangers of advancements in robotics, as the industry is currently undergoing dramatic changes.The five-day conference, which is organized by the Institute of Electrical and Electronics Engineers (IEEE), took place in China for the first time ever since its first session in 1984, which took place in the city of Atlanta in the United States.Media reports show that Japan, the Republic of Korea (ROK) and several Western countries have already drafted rules about the safe use of robots.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

SAN FRANCISCO, April 28 (Xinhua) -- Microsoft Corp. on Thursday posted quarterly revenue and earnings that both beat analysts' expectations.In its fiscal 2011 third quarter ended on March 31, the software giant reported revenue of 16.43 billion U.S. dollars, up 13 percent from the same period a year earlier.Net income and earnings per share were 5.23 billion dollars and 61 cents, representing increases of 31 percent and 36 percent respectively year-on-year.Analysts had expected earnings of 56 cents per share on revenue of 16.19 billion dollars, according to Thomson Reuters."We delivered strong financial results despite a mixed PC environment, which demonstrates the strength and breadth of our businesses," Peter Klein, chief financial officer at Microsoft, said in a statement."Consumers are purchasing Office 2010, Xbox and Kinect at tremendous rates, and businesses of all sizes are purchasing Microsoft platforms and applications," he added.Revenue at four of Microsoft's five major divisions posted double-digit growth in the quarter, indicating the increase of technology spending by enterprises as well as strong demand for the company's entertainment products.The entertainment and devices division saw the biggest revenue growth of 60 percent, which according to Microsoft, were driven by strong demand for its Kinect hands-free motion control system for Xbox 360 and continued strong sales of Xbox 360 console.However, revenue for the division of the company's flagship Windows operating system dropped 4 percent in the quarter, which Microsoft said was "in line with the PC trends."The performance of the Windows division may fuel new concerns that Microsoft's dominance in software for PCs is being threatened by Apple's iPad and tablet computers running other operating systems, some analysts noted.

BEIJING, May 4 (Xinhuanet) -- Children with autism have slightly bigger brains than children without the condition, a study suggests.The research published in the May issue of Archives of General Psychiatry noted the difference in the brain size appears related to increased rates of brain growth before age 2.The researchers from the University of North Carolina also pointed out that though the enlargement continues, the increased growth does not.In 2005, the researchers studied a group of 2-year-old children, and found out the ones with autism had brains that were 5% to 10% larger than children without it.Now the researchers assessed the same group of children at age 5, the psychiatrists re-scanned the brains of 38 children with autism and 21 without the condition. The autistic children still had slightly larger brains, but they had grown at the same rate as the comparison group.This finding could lead to a better understanding of the genes that drive autism, which, in turn, could lead to earlier identification and treatment of the disorder, said study researcher Joseph Piven, MD, according to media report.
