WELLINGTON, July 26 (Xinhua) -- Children born early are less likely to develop serious behavioral problems than previously thought because previous studies may have relied too much on the opinions of "sensitive" parents, according to a controversial New Zealand research.The study by the Child Development Research Group at the University of Canterbury looked at the emotional and behavioral adjustment of children born very preterm (VPT).It showed that by age 6 children born very preterm (less than 33 weeks) were at an increased risk of emotional and attentional problems when compared with their full term peers, said a statement from the university.However, the findings suggested the risks may be lower than previous studies had suggested, because previous studies primarily relied on parents to provide information on their children's conditions, said lead author Samudragupta Bora."While parents are an important source of information about their child, it is also important to gather information from other significant people in the child's life such as their classroom teacher," said Bora.Bora and other members of the research team, found that parents reported higher rates of emotional and attention problems in their children than teachers did."Having a baby born prematurely is an extremely stressful experience for parents. During their baby's stay in the neonatal unit most parents will have been alerted to the possibility of their child developing problems such as behavioral difficulties in the future due to being born too early. Therefore, very understandably, many parents of these children are very sensitive to the possibility of developmental problems," he said."The use of multiple informants - parents, teachers and clinical observation - to assess VPT children's well-being is important to minimize the effects of report source bias and the over or under-identification of adjustment problems in children born VPT," said Bora."This is controversial because it shows that reliance on parents or teachers alone can lead to data validity issues."Although children born VPT were at higher risk of showing emotional and attentional problems, the risks of more severe problems were relatively modest, said Bora.The findings have been published the Journal of Paediatrics and Child Health.

SAN FRANCISCO, June 9 (Xinhua) -- Hewlett-Packard Co. (HP) on Thursday announced that its tablet computer, HP TouchPad, will go on sale in the United States on July 1.Two versions of HP TouchPad, with the option of either 16 gigabytes or 32 gigabytes of internal storage, and both only with Wi-Fi connection, will be available in the United States for 499. 99 U.S. dollars and 599.99 dollars respectively, the company said in a statement.The product will hit stores in Britain, Ireland, France and Germany a few days later and in Canada in mid-July, with availability scheduled to follow later this year in Italy, Spain, Australia, China's Hong Kong, New Zealand and Singapore.Preorders in North America and Europe will begin on June 19, HP said.HP did not release the price details when it introduced TouchPad on Feb. 9. The black device, with a 9.7-inch touch screen, runs webOS operating system, a mobile platform developed by Palm, a smartphone maker acquired by HP last April for 1.8 billion dollars.

BEIJING, Sept. 26 (Xinhua) -- Nobel laureates on Monday cast doubt on a European experiment that purportedly demonstrated the ability of neutrinos to move faster than the speed of light.They made the remarks in Beijing prior to a forum for Nobel laureates."I'm willing to bet money that it's not correct," said Professor George Smoot III, winner of the 2006 Nobel Prize in Physics and a professor at University of California, Berkeley, referring to an experiment result claiming that particles apparently travel faster than light.The experiment reported an anomaly in the flight time of neutrinos, or electrically neutral subatomic particles, from the European Center for Nuclear Research (CERN) in Switzerland to a laboratory located 730 kilometers away in Italy.Particles were clocked transmitting at a speed of 300,006 kilometers per second, about 60 nanoseconds faster than the speed of light.Smoot said that the claims "did not make sense" and should be verified by other scientists first."There are many distortions in physics. You have to have a very high standard to see if something is truly correct," he said.The unverified findings were published on Sept. 22 in the scientific journal Nature. European researchers working in a team called OPERA (Oscillation Project with Emulsion-Racking Apparatus) projected masses of neutrinos from CERN and then collected the particles using a massive detector in Gran Sasso, south of Rome.Other scientists, as well as the OPERA team themselves, have voiced doubts regarding the experiment's results.The findings, CERN claims, could pose far-reaching potential consequences once verified.If correct, the results would bring Einstein's theory of special relativity into question. Under this theory, a physical object cannot travel faster than the speed of light in a vacuum."If really it is right, we have to rethink everything we know," said Chris Llewellyn Smith, former director of CERN.Smith claimed the unprecedented discovery was too exceptional to find proof."If somebody makes a very exceptional claim, then very exceptional proof would need to come from another experiment, saying the same thing. But we don't have the other thing," Smith said.Carlos Rubbia, a Nobel Laureate who won the prize for physics in 1984, is in charge of a team of more than 100 scientists at CERN."What it is pretending to find, in my view, is unbelievably surprising," Rubbia said."Frankly, I have the feeling that this is still a very experimental consideration," Rubbia said.He also believes that revealing the findings to the public was a mistake as it remained an experimental process and no conclusion could be drawn without the results of another experiment.Despite the possibility of verification, Einstein's special theory of relativity will remain valid."I will be very, very surprised that, at last, Einstein will not be the winner," Rubbia said.To achieve a breakthrough, Rubbia has urged for more joint cooperation on verifying the test results. International cooperation on this issue "is a must.""It requires coordination from all nations," said Rubbia.The 2011 Nobel Laureates Beijing Forum will be held from Sept. 28 to 30 under a theme of "innovation and development."

WASHINGTON, Aug. 4 (Xinhua) -- Observations from NASA's Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars, the U.S. National Aeronautics and Space Administration (NASA) announced Thursday.Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere."The best explanation for these observations so far is the flow of briny water," said Alfred McEwen of the University of Arizona, Tucson.McEwen is the principal investigator for the orbiter's High Resolution Imaging Science Experiment and lead author of a report about the recurring flows to be published in Friday's edition of the journal Science.Seven such sites on the planet have been confirmed, with 20 more possible, McEwen said."What makes these new observations so interesting is they occur at much lower latitudes where temperatures are much warmer and where it's actually possible for liquid water to exist," said Arizona State University geophysicist Phil Christensen, one of the scientists who studied the images beamed back from the orbiter.The study does not prove water exists, but identifies it as the best explanation. It's worthwhile to think about alternative reasons for these observations, but none seems to fit as well as briny water, McEwen said."I think it's going to be laboratory experiments on Earth that give us the best confirmation or refutation," he said.

SHANGHAI, July 19 (Xinhua) -- Baidu Inc., the largest Chinese search engine based in Beijing, said Tuesday it closed a deal that allows the company to provide download services of music from Universal Music, Warner Music and Sony Music.According to the deal signed between Baidu and One Stop China (OSC), a joint venture of the three music companies, Baidu will pay them on a per-play and per-download basis for all tracks delivered through its MP3 server, said a press release provided by Baidu.Users can have access to the authorized music free of charge, and Chinese songs, both in Mandarin and Cantonese, and some global content provided by the three music companies will be included in the catalogue.Baidu also launched a social music platform called "Baidu ting!" through which users can obtain and share some music-related information and content.Li Xinzhe, CFO of Baidu, described the deal as a "milestone" that can benefit not only Baidu and its partners but also music lovers and the privacy-stricken industry.Wang Bin, secretary general of Copyright Union of Internet Society of China, predicted that it would have a demonstrative effect on the Internet sector.In 2008, Universal, Warner and Sony Music sued Baidu for at least 63.5 million yuan (9.8 million U.S. dollars) in copyright infringement.
