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.

WASHINGTON, Feb. 7 (Xinhua) -- The U.S. International Trade Commission (USITC) determined Monday that imports of drill pipe and drill collars from China threatened the U.S. industry with material injury.As a result of the USITC's affirmative threat determinations, the U.S. Commerce Department will issue anti-dumping and countervailing duty orders on imports of these products from China.On January 4, the U.S. Commerce Department announced its affirmative final determinations in the anti-dumping duty and countervailing duty investigations on imports of drill pipe from China. The department determined that Chinese producers and exporters had sold drill pipe in the United States at margins ranging between 0.00 and 69.32 percent, while they have received countervailable subsidies of 18.18 percent ad valorem.In the anti-dumping investigation, mandatory respondent China's DP Master Manufacturing Co., Ltd. and Jiangyin Liangda Drill Pipe Co., Ltd. received a dumping rate of 69.32 percent. Baoshan Iron and Steel Co., Ltd. as well as Shanxi Yida Special Steel Imp. and Exp. Co., Ltd. each received a dumping rate of 0.00 percent, according to the department.The USITC did not specify the combined value of imported drill pipe and drill collars from China in the statement. A determination will be considered as affirmative if there is a 3-3 voting result within the USITC Commissioners.Drill pipe and drill collars are hollow drill string components used in drilling rigs, particularly those intended to extract oil and gas, to transmit power and conduct lubricant during the drilling process.

BAODING, Feb. 2, (Xinhua) -- All-out efforts should be made to combat drought for a summer grain harvest, said Chinese President Hu Jintao Wednesday in an inspection tour to north China's Hebei Province."We need to adopt comprehensive measures to ensure supply of capital, technologies, facilities and materials to enable winter wheat to safely grow through the winter," said Hu, when inspecting drought conditions at a wheat field in Xishanbei Township of Baoding City, Hebei.Over the past three months, North China has been hit by severe drought, seriously threatening normal agricultural production.Hu, who is also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the inspection visit in Baoding from Tuesday to Wednesday, to welcome the Spring Festival, or China's Lunar New Year, with local officials and residents.Hu beat a drum together with villagers during a new year celebration in Shijiatong Village, Xishanbei Township of Baoding.The president visited the home of Yan Deshu, an aged CPC member in the village, and pasted the Chinese character "Fu", meaning fortune and happiness, on the gate of Yan's yard.Hu also visited a long-distance coach station in Baoding, and extended Spring Festival greetings to passengers, station workers and volunteers.Hu inspected a unit of armed police in Baoding and made Chinese dumplings together with the officers and soldiers.

BEIJING, March 24 (Xinhuanet) -- A new study has found that Actos, a medicine treats onset diabetes, could also reduce the diabetes risk in people with prediabetes.The study, which was published Wednesday in New England Journal of Medicine, followed 602 prediabetics whose obesity, ethnicity, family history and other factors put them at high risk of developing diabetes.The research findings showed that Actos, generically known as pioglitazone, reduced the odds of developing Type 2 diabetes by 72 percent in people with prediabetes.Only 2.1 percent of those who took Actos developed diabetes each year over the three years of the study, compared with 7.6 percent of those who took a placebo.Lead author of the study Ralph DeFronzo said, "The 72 percent reduction is the largest decrease in the conversion rate of pre-diabetes to (Type 2) diabetes that has ever been demonstrated by any intervention, be it diet, exercise or medication."However, Actos can have significant side effects, including water retention, moderate weight gain, and increased risk of bone fractures.

LOS ANGELES, April 7 (Xinhua) -- Unrecycled energy-efficient bulbs release tons of mercury into the environment every year, raising an environmental concern, it was reported on Thursday.Demand for the energy-efficient lights -- the compact fluorescent light bulb (CFL) -- is growing as government mandates for energy-efficient lighting take effect, yet only about two percent of residential consumers and one-third of businesses recycle the new bulbs, the Los Angeles Times said, quoting the Association of Lighting and Mercury Recyclers (ALMR).Each CFL contains up to five milligrams of mercury, a potent neurotoxin that's on the worst-offending list of environmental contaminants, the report said.As a result, U.S. landfills are releasing more than four tons of mercury annually into the atmosphere and storm water runoff, the Journal of the Air and Waste Management Association said in a study published by the paper.The federal Clean Energy Act of 2007 established energy- efficiency standards for light bulbs that dimmed the future for old-fashioned incandescents, which don't meet those standards. Incandescents are to be phased out by 2014 in the U.S., and California passed even stricter rules, calling for store shelves to be cleared of them by 2013.The old-style bulbs are just too wasteful, converting to light only 10 percent of the energy they consume. The rest is squandered as heat.Sales of energy-efficient alternatives like CFLs, halogen bulbs and LEDs have been growing steadily, with the low-cost CFLs the biggest sellers, according to the paper.If every California household replaced five incandescent bulbs with CFLs, the move would save 6.18 billion kilowatt-hours and prevent the annual release of 2.26 million tons of heat-trapping carbon dioxide, according to the California Energy Commission. That 's equivalent to taking 414,000 cars off the road.But no federal law mandates recycling of household fluorescent lights. Federal rules exempt some businesses, based in part on the number of bulbs used, said Paul Abernathy, executive director of the ALMR, which is based in Napa, Calif.Several states, including California, Massachusetts, Maine, Vermont and Minnesota, do require that all households and businesses recycle fluorescents, the paper said.But the ALMR said compliance is low because of a lack of convenient drop-off options.
