BEIJING, May 10 (Xinhuanet) -- Autism spectrum disorder may be under diagnosed and under reported worldwide and rigorous screening is needed for accurate estimates, said researchers in Monday's American Journal of Psychiatry.Researchers from the Yale Child Study Center, George Washington University and other leading institutions screened every child aged 7 to 12 in Ilsan district of the city of Goyang, a community of 488,590 in South Korea, and found more than two-thirds of ASD cases in the mainstream school population unrecognized and untreated.They estimated the prevalence of ASD in South Korea to be 2.64 percent, or approximately 1 in 38 children.The figure is more than twice the rate usually reported in the developed world. Even that rate, about 1 percent, has been climbing rapidly in recent years — from 0.6 percent in the United States in 2007, for example.“From the get-go we had the feeling that we would find a higher prevalence than other studies because we were looking at an understudied population: children in regular schools,” said the lead researcher, Dr. Young-Shin Kim, a child psychiatrist and epidemiologist at the Yale Child Study Center.By contrast, other research groups measure autism prevalence by examining and verifying records of existing cases kept by health care and special education agencies, but leaving out many children whose parents and schools have never sought a diagnosis.Kim said the researchers concluded autism prevalence estimates worldwide may increase if rigorous screening and comprehensive population studies are used to produce prevalence estimates.But it is suggested the findings did not mean that the actual numbers of children with autism were rising, simply that the study was more comprehensive than previous ones.

SAN FRANCISCO, April 18 (Xinhua) -- Apple Inc. has sued Samsung Electronics Co. over patent infringement in a latest suit, U.S. media reported Monday.The suit, filed last Friday in U.S. District Court in Northern California, alleged that Samsung's smartphones, such as "Glaxy S 4G" and "Nexus S," and the Galaxy line of tablet computers violated Apple's patent and trademark, according to All Things Digital, a technology and startup company news site."It's no coincidence that Samsung's latest products look a lot like the iPhone and iPad, from the shape of the hardware to the user interface and even the packaging," the report quoted an Apple representative as saying.Intellectual property suits can be often seen among mobile computing rivals, including suits between Microsoft and Motorola, a suit by Oracle against Google, and Apple's patent dispute with Nokia and HTC.Although Samsung supplies chips for a number of Apple products, Apple CEO Steve Jobs once openly mocked Samsung and other tablet makers as "copycats" during the iPad2 launch. Last month, Apple is reportedly partnering with China's Taiwan Semiconductor Manufacturing Co. to make iPad chips.

BEIJING, Feb. 12 (Xinhua) -- China said late Saturday that members of the United Nations should work for a broadly-based consensus on the reform of the UN Security Council.Foreign Ministry spokesman Ma Zhaoxu made the remarks in response to a relevant question.Media reports had it that a recently-released declaration by some countries said most of UN member nations supported enlarging the council with new permanent and non-permanent members, and insisted tangible results be achieved in this regard during the Current Session of the UN General Assembly.Ma said China held that UN member nations should seek for a package of solutions for the reform, on the basis of broad and democratic consultation among member nations to accommodate interests and concerns of all parties.He said though some positive progress had been made since inter-government negotiations regarding the reform of the UN Security Council were launched, there were still serious differences within all parties over certain important issues about the reform.China advocated that the more differences the member countries had on the reform, the more necessary for UN member nations to enhance dialogue and consultation, he said."Experience has proven that presetting results for the reform or forcing premature reform plans will not only undermine the unity of UN member nations, but also harm the reform process, which will not be in line with any party's interests," he said.China is ready to maintain contact with all relevant parties, and make joint efforts with other member nations to push forward the reform in a way which can be conducive to safeguarding the overall interests of UN and the unity of the member nations, said Ma.

BEIJING, May 20 (Xinhuanet) -- Scientists have discovered a Jupiter-sized exoplanet that is completely unbound from a host star, according the scientific journal "Nature" published Thursday.The research was conducted by astrophysicists from Osaka University in Japan.Using the technique called "gravitational microlensing", scientists turned their telescopes towards the centre of the Milky Way and detected this "lonely planet" moving in a extremely large orbit, which suggested it does not connect to any solar system.Then they estimated the total number of such wondering planets could be as many as 400 billion, based on the detection efficiency. This number far outnumbers the main-sequence stars such as our Sun."This is an amazing result, and if it is right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut.And scientist began to consider the possibility that liquid water could exist on this kind of unbound planets. "That might be an attractive possibility for life," said David Stevenson, a planetary scientist at the California Institute of Technology.
