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 4 (Xinhua) -- Web exploit toolkits, or " packaged" attack frameworks that can be traded online, are rapidly growing as the top cybercrime weapon due to ease of use and high success rate, a new report has found."When it comes to conducting online crime, exploit toolkits are the weapon of choice for many cyber criminals," said the "2010 Top Cyber Security Risks Report" published by Hewlett-Packard Co. (HP) on Monday.The trend started in 2006 with the release of WebAttacker, considered by many to be the first modern day web exploit toolkit, according to the report.An emerging trend ensued and soon took off, and today the Internet is subjected to hundreds of exploits originating from these toolkits."With the ever-increasing, web-based criminal activity, the number of exploit toolkits has skyrocketed and shows no signs of slowing down," the report stated.Though protecting against attacks originated with web exploit toolkits is becoming increasingly difficult, there are ways to minimize the risk of infection, said the report, noting that one of the most effective defenses is to install patches onto host systems.The report also found that while the number of attacks against known vulnerabilities continues to rise, the number of discovered vulnerabilities has plateaued in 2010."We've discovered that rather than investing resources to uncover new exploits, attackers are focused on current, unpatched vulnerabilities in web applications, social networking sites and Web 2.0 interfaces," Mike Dausin, a manager at HP Digital Vaccine Labs, said in a statement.Data from the report showed that nearly half of all reported vulnerabilities exist in web applications, and third-party plug- ins to content management systems have become the leading cause of web application vulnerabilities.

BEIJING，March 11 (Xinhuanet) --A poor diet during pregnancy may result in health problems such as diabetes for the offspring in later life, according media reports Friday quotting a new research.Based on a study of rats, researchers from the University of Cambridge altered the protein content of the mother's diet during pregnancy as they found that rats were more vulnerable to the effects of diseases if their mothers were malnourished while they were pregnant.Further, the study also showed that an imbalanced diet in the expectant mother can compromise the long-term functioning of a gene in the child. And the gene, named Hnf4a, is believed to play a major role in the development of the pancreas and in the production of insulin.The researchers held similar mechanisms seen in the rat study could occur in humans, and that the effects might be felt by more than just the immediate offspring."What is most exciting about these findings is that we are now starting to really understand how nutrition during the first nine months of life spent in the womb shape our long term health by influencing how the cells in our body age," said Susan Ozanne, senior author of the paper and senior fellow from the Institute of Metabolic Science at the University of Cambridge.And Jeremy Pearson, associate medical director at the British Heart Foundation, said: "The reasons why are not well understood, but this study in rats adds to the evidence that a mother's diet may sometimes alter the control of certain genes in her unborn child.""It's no reason for expectant mothers to be unduly worried. This research doesn't change our advice that pregnant women should try to eat a healthy, balanced diet," he added.

SAN FRANCISCO, April 27 (Xinhua) -- Apple Inc. on Wednesday denied the alleged location-tracking practice of its mobile operating system, saying it will release software updates to make iPhone store less location information to quell public concerns over privacy.CLARIFICATION"Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so," the company said in a statement."Users are confused, partly because the creators of this new technology (including Apple) have not provided enough education about these issues to date."According to the statement, the location data researchers saw on iPhone is a database of Wi-Fi hotspots and cell towers around users' current location that Apple is maintaining to help iPhone rapidly and accurately calculate its location when requested. It noted Apple cannot locate iPhone users based on Wi-Fi hotspot and cell tower data as the information is in an anonymous and encrypted form.Apple admitted that part of the location data (Wi-Fi hotspots and cell towers) is backed up on iTunes, which means it could be possible that people with access to iPhone users'computer may get their location information. It said a software update has been planned to cease the backing-up.It is also planning to provide an update to limit the data storage on iPhone, in response to questions that the device has been storing location data since the release of iOS 4 operating system last June.Apple said it is a bug that iPhone keeps storing location data even if its location services are disabled, noting it will fix this through a software update in the coming weeks.The company also reiterated its focus on personal information security and privacy."Pretty much what I expected at this stage. The response is measured and the update should fix the problem," Alasdair Allan, one of the two British researchers who first announced the discovery of stored location data on iPhone, said on his Twitter account.ALLEGATIONThe statement on Wednesday is Apple's first official response to the location-tracking allegations.Worries on the iPhone tracking issue first surfaced last Wednesday when two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data since June 21, 2010.Last Friday, The Wall Street Journal reported its security analysts had found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.The newspaper then reported on Sunday that its analysts had also found iPhone is collecting and storing user's location data even when location services are turned off.PRESSUREThe Cupertino, California-based company has been facing mounting pressure from lawmakers, customers as well as media reports following the revelations.The U.S. House Energy and Commerce Committee on Monday sent letters to six developers of mobile device operating systems, including Apple and Google, demanding Apple's explanation on implications of alleged tracking for individual privacy and federal communications policy.Also on Monday, Minnesota Senator Al Franken, chairman of the U. S. Senate Judiciary Subcommittee on Privacy, Technology and the Law, announced he had scheduled a mobile privacy hearing on May 10 and asked representatives from Apple and Google to speak at the hearing.Meanwhile, Lisa Madigan, Attorney General of U.S. state of Illinois, on Monday called for a meeting with Apple and Google executives on the location-tracking reports, citing her ongoing effort to protect consumers' personal information online.Last Friday, two iPhone users filed a class action suit against Apple in Tempa, Florida, accusing the company of invasion of privacy and computer fraud and seeking a judge's order to bar the alleged data collection.Last Thursday, U.S. congressman Edward Markey asked Apple CEO Steve Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."On Saturday, Markey called for a congressional investigation into the privacy practices of Apple and Google. In a statement, he made clear that he thinks the data collection is potentially dangerous, saying predators could have hacked into an iPhone or Android phone to find out children's location information.Apple is also reportedly being investigated in South Korea, France, Germany and Italy over the alleged tracking practice.

BEIJING, Feb. 21 (Xinhua) -- China's domestic air travelers, as well as international passengers in and out of China, will be the biggest boost to airline industry growth over the next four years, according to an industry outlook report by the International Air Transport Association (IATA) Monday.Of the world's expected 800 million new travelers by 2014, about 181 million new passengers will come from China's domestic air routes, while another 33 million will be passengers flying to or from China via international routes, IATA said.China's 181 million domestic air passengers growth will lift the country's domestic passenger throughput to 379 million by 2014, only behind the United States in the world's aviation traveler volume ranking, according to IATA.The United States will remain the largest single country market for domestic passengers, with 671 million domestic air travelers and international passengers by then, according to IATA's forecast.The world's air travelers will top 3.3 billion by 2014, up by 800 million from the 2.5 billion in 2009, while world air cargo will rise to 38 million tonnes from 26 million tonnes in 2009."The forecast indicates that the world will continue to become more mobile. This creates enormous opportunities but also presents some challenges," Giovanni Bisignani, IATA' s Director General and CEO, said in the outlook report."We will need even more efficient air traffic management, airport facilities and security programs," he said, adding the shadow of the global economic recession is expected to remain over parts of the industry for some time to come.He said lingering consumer debt, high unemployment and austerity measures will dampen growth rates in Europe and North America, shifting the industry's focus eastwards.By 2014, 1 billion people will travel by air in the Asia-Pacific region, accounting for 30 percent of the global total, up from 26 percent in 2009, he added.
