BEIJING, Oct. 18 (Xinhuanet) -- Autism can likely develop when low birth weight babies are combined with other factors such as environment and genetic predisposition, new research suggests.Researchers from the University of Pennsylvania School of Nursing and School of Medicine identified 1,105 children who weighed less than 2,000 grams at birth between Oct. 1, 1984, and July 3, 1989.Sixteen years later, researchers were able to reach 623 of those children, and used a questionnaire to screen them for autism spectrum disorders.When 189 of the children turned 21 years old, 60 percent of those who screened positive for an autism spectrum disorder, and 24 percent of those who screened negative with the condition. All in all, the rate of autism spectrum disorders among the study participants with low birth weights was five times higher than the general.Autism spectrum disorder makes people have difficulty communicating, difficulty interacting in social situations, and restrictive or repetitive interests, said study co-author Jennifer Pinto-Martin, a researcher in the University.Those with mild autism spectrum disorders, "may only want to talk about one subject," Pinto-Martin said. "They're perfectly functional. They can go to college. They can hold a job." Premature babies are often born with low birth weights, though full-term babies can also have the condition. The research suggests a need not only for better prenatal care to reduce the number of premature babies, but also a need for early diagnosis and intervention for people with autism.

HAIKOU, Dec. 16 (Xinhua) -- China will actively push forward maritime cooperation with the 10 members of the Association of Southeast Asian Nations (ASEAN) in light of the guidelines on conduct in the South China Sea, a Foreign Ministry official has said.Assistant Foreign Minister Liu Zhenmin made the remarks during an international seminar on implementing the Declaration on Conduct of Parties in the South China Sea (DOC) and maintaining the navigational freedom and security of the waterway.Early next year, China will hold a senior officials' meeting and working group meeting with ASEAN countries on the implementation of the 2002 Declaration on the Conduct of Parties in the South China Sea (DOC), Liu said in an interview with Xinhua on the sideliens of the seminar held in Haikou, Hainan Province, from Dec. 14-15..The senior officials' meeting is a guiding mechanism for implementing the DOC at governmental level. Under it, China will hold a series of seminars and carry out a set of cooperative projects, so as to further advance cooperation with ASEAN nations, he said.Chinese Premier Wen Jiabao proposed to establish a three-billion-yuan China-ASEAN maritime cooperation fund at the 14th China-ASEAN summit and the Commemorative Summit to Celebrate the 20th Anniversary of China-ASEAN Relations in November.China hopes the fund will contribute to the implementation of the DOC and further enhance cooperation with ASEAN nations, said Liu.The State Oceanic Administration held a South China Sea oceanography seminar in Qingdao on Dec. 12, he said, adding China will hold a series of seminars on topics ranging from marine research, search and rescue, environmental protection, navigation safety and combating maritime crimes.Liu said the maintenance of maritime security as well as navigation safety and freedom is very important to East Asian countries, for the economic development of East Asia is largely export-oriented.As an important pathway for foreign trade for China, Japan, the Republic of Korea and the ASEAN nations, security on the South China Sea is critical for these countries' economic development, he said.Stressing that navigation freedom and security on the sea should be guaranteed, he said China will continue to strengthen cooperation with countries surrounding the South China Sea to protect against threats.The DOC was signed by China and the ASEAN countries in November 2002 as a code of conduct for all parties involved in diplomatic issues in the South China Sea.It is a political document aimed at safeguarding peace, stability and prosperity in the South China Sea, advancing pragmatic cooperation and creating favorable conditions for the interested countries to ultimately settle their disputes by peaceful negotiation.

SAN FRANCISCO, Dec. 29 (Xinhua) -- The United States Patent and Trademark Office on Thursday published a patent application from Apple related to face and presence detection for iOS devices, which is expected to be one of the next chapters for mobile security.According to AppleInsider, a news and rumor website focusing on Apple, the patent is entitled "low threshold face recognition" which is a low-computation solution for quickly and accurately recognizing a user on iPhone, iPad, iPod Touch and MacBook.Patently Apple, a blog focusing on Apple's latest intellectual properties, said that iOS devices would acknowledge the presence of the potential user by turning on the display and then trigger a subsequent process for recognizing the potential user's face.Currently, most face recognition systems tend to be robust ones working in various lighting conditions, orientations, scale and etc., which will require computing resources and drain battery life. There are also security-type face recognition systems working under controlled lighting conditions which could be ineffective due to factors like proximity of the user to the camera.Google's latest Android 4.0 operating system, codenamed Ice Cream Sandwich, already features face detection. But it is reported that the feature doesn't always work and can be bypassed by using a photograph of the phone's owner.Apple's solution would reduce the impact of lighting conditions and biometric distortions on an image, said AppleInsider, citing the filing. Apple said it would rely on a "high information portion" of a human face, such as eyes, mouth or the tip of a user 's nose.The "likely presence" of a human face in front of the camera would be captured through an "orange-distance filter" which would also be used to detect the potential user's skin tone and measure the distance of their face from the camera.Meanwhile, iOS devices could also be set to recognize faces of multiple users, presenting each user with a personalized configuration.According to AppleInsider, the patent application was first filed by Apple in June, 2009.Analysts said that the proposed technology could be Apple's next big innovation as it has record of redesign and give its unique appeal to products that have not caught on with the general public.

MANILA, Jan. 9 (Xinhua) -- Philippine telecommunication companies cut off the signal of mobile phones in parts of Manila where millions of people are expected to converge for the feast of the Black Nazarene on Monday.Philippine Deputy Presidential Spokesperson Abigail Valte said that the move was part of the precautionary measures that the government has been undertaking following terror threats."Malacanang (Palace) confirms that the government asked the telcoms to temporarily disconnect their services in the route of the Black Nazarene procession as part of the security measures agreed upon during the meeting on Sunday," she said in a regular news briefing.She said that the disruption in mobile services would last for the entire duration of the procession of the Black Nazarene.She admitted that the signal of the cellular phones was disconnected in the past, and terrorists used the mobile phones as triggering device for bombs.Asked if the government considered the possible losses of telecommunication firms due to the disconnection of signals, Valte said, "as holders of a franchise, the public safety is paramount."President Benigno Aquino III personally warned on Sunday the public to be cautious in joining the feast of the Black Nazarene amid possible terrorist attacks. The government is expecting 9 million devotees to participate in the celebration.The Black Nazarene is the patron saint of Quiapo church. The statue was brought to Manila by a Spanish priest in 1607. It was aboard a ship that caught fire, the image was burned, and it came to be known as the "Black Nazarene" which people have since decided to preserve and honor.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."
