WASHINGTON, Oct. 3 (Xinhua) -- Overweight or obesity may put children at three times greater risk for high blood pressure than those of normal weight, according to researchers from the Regenstrief Institute and Indiana University (IU) School of Medicine.Their study will appear in the November issue of Hypertension: Journal of the American Heart Association with advance online publication on Monday.More than 1,100 healthy Indiana school children were followed for nearly five years. The researchers found that when body mass index (BMI) reached or exceeded the 85th percentile for the age and gender of the child -- designated as being overweight -- the risk of high blood pressure nearly tripled. Obesity was defined as a BMI percentile higher than 95th. BMI is a measurement of body fat calculated from weight and height.Among study participants, 14 percent of overweight or obese children were pre-hypertensive or hypertensive, compared with 5 percent of normal weight children. These findings were consistent across age, gender and race.The average age at time of study enrollment was 10.2 years. Each child was assessed approximately eight times during the course of the study. All were healthy children and none were taking medication affecting blood pressure."Higher blood pressure in childhood sets the stage for high blood pressure in adulthood," said Regenstrief Institute Investigator Wanzhu Tu, professor of biostatistics at IU School of Medicine, who led the study. "Targeted interventions are needed for these children. Even small decreases in BMI could yield major health benefits."The researcher also found that leptin, a protein hormone which is involved in body weight regulation and metabolism, was positively associated with increased blood pressure in overweight and obese children.

COPENHAGEN, Nov. 3 (Xinhua) -- The launch of Shenzhou-8 and the successful docking with Tiangong-1 in outer space represented a milestone in both Chinese and international space programs, Danish space scientist and media said Thursday.Michael Linden-Voernle, an astrophysicist at the Tycho Brahe Planetarium in Copenhagen, said new possibilities have opened for both Chinese and international space programs with high expectations."The recent launch of the Tiangong-1 module and now the successful docking with the Shenzhou-8 spacecraft is a very important step - a milestone for the Chinese space program in order to realize the goal of having a permanent presence in space. That means a large space station so this is really an important step, a major milestone," Linden-Voernle told Xinhua in an interview here on Thursday.Besides, a number of Danish news media reported the event, hailing it as a "historic and successful docking." The influential daily Politiken placed a two-minute's video for the successful coupling on its website and showed scenes from the Shenzhou-8 docking with Tiangong-1 together with a short commentary."Tonight two Chinese spacecraft made the historic and successful docking above the atmosphere for the first time ever. China had been the third country in the world after the United States and Russia to master the technique of docking in space. China has laid the foundation for its dominance in space," Politiken said.Jyllands-Posten, one of the bestselling newspapers in Denmark, carried a report with a brief description of China's first space docking under the headline "China closer to its own space station.""As the third country in the world, China has docked two spacecraft together perfectly in space," said Jyllands-Posten.China's unmanned spacecraft Shenzhou-8 and its space lab module Tiangong-1 rendezvoused early Thursday, successfully completing the country's first-ever space docking.

SAN FRANCISCO, Nov. 1 (Xinhua) -- Apple announced on Tuesday that its latest iPhone 4S smartphone will be available in China's Hong Kong, South Korea and 13 additional countries next Friday.Customers will be able to pre-order iPhone 4S beginning this Friday, the Cupertino, California-based company said in a statement.The other 13 countries are Albania, Armenia, Bulgaria, El Salvador, Greece, Guatemala, Malta, Montenegro, New Zealand, Panama, Poland, Portugal and Romania.So far, some owners have been complaining about the shorter battery life on their new iPhone 4S handsets. Apple is reportedly investigating the issue and has not made official comments yet.The iPhone 4S looks the same as the previous iPhone 4 but has major hardware upgrade inside. Apple announced sales of more than four million units of iPhone 4S in the three days after its launch in the United States on Oct. 14.The iPhone 4S now is available in 29 countries and is expected to arrive in stores in more than 70 countries by the end of this year.

JERUSALEM, Dec. 11 (Xinhua) -- Kfir Damari, a communication systems engineer, has a dream: to land a miniature spacecraft on the moon sometime in 2013.Damari is one of the founders of Team SpaceIL, a non-profit organization representing Israel in the Google Lunar X Competition. The prize: 20 million U.S. dollars to the first of the 26 international teams currently registered that lands an unmanned craft on the moon, moves it a minimum of 500 meters across the lunar surface and transmits live high-resolution images back to earth."It's a tough mission, but I believe that if everyone in Israel joins hands it's possible," Damari told Xinhua.It is exactly the kind of entrepreneurial spirit that Israel, a country largely void of natural resources, counts on to make it a global leader in technological innovation.The two other men behind the initiative are Yonatan Winetraub, 25, a systems engineer at Israel Aerospace Industries (IAI) and a graduate of NASA's International Space University, and Yariv Bash, 31, a computer scientist and electronics engineer. The three first met at an innovation conference held by IAI a year ago.They describe the lander as a nano-satellite, whose design was revealed at the project's official inauguration ceremony on Thursday. The vessel weighs 100 kg, 80 percent of which are fuel, and is outfitted with rocket boosters and a panoramic camera."It's somewhat of a cellular phone sitting on a large fuel tank. All the technology that we require is basically contained in a typical smartphone with its communication and imaging features," Damari said.Launched in 2007, the Lunar X Prize aims to encourage space enthusiasts and engineers worldwide to develop cheap technologies for robotic space exploration.The Israelis have slated a modest 15 million U.S. dollars for the endeavor, 90 percent of which must come from private contributions according to the competition's rules. They have already raised 3.5 million dollars.The fact that they have formed a non-profit NGO in itself is worthy of praise. Most other teams have obtained the patronage of private corporations for whom money is not a problem, with some reportedly allotting up to 100 million U.S. dollars.To compensate for the disparities in funding, Damari and his partners have enlisted the support of 120 local volunteers, many of them engineers holding top positions in the technological and scientific community as well as the country's leading defense industries.Rona Ramon, the widow of Israeli astronaut Ilan Ramon killed aboard the Columbia Space Shuttle in 2003, was one of the sponsors too.In a bid to keep costs down, SpaceIL is heavily relying on the existing knowledge accumulated by Israel's defense industries over the past decades in building and launching mainly small, lightweight communications and military surveillance satellites into space.The challenge, Damari said, is to take that know-how a step further. The professionals who have volunteered for the project, among them some of Israel's most revered space experts, are currently grappling with several issues, including the ignition system, optic-visual navigation, beaming imagery to earth and the intricacies of enabling the nano-satellite a smooth lunar landing.SpaceIL is still searching for a third party that they will lease to launch their vehicle into space. Once there, they will have to navigate it to the moon on their own.While 20 million U.S. dollars is a major motivator for anyone, the Israelis said they're not seeking personal gain, but rather plan to invest the prize money in the vision that originally prompted their registration in December last year: inspiring the country's younger generation to pursue engineering and the sciences and to dream big, just like Neil Armstrong did when he disembarked from the Apollo 11 and took the first step on the moon in 1969.The funds, they said, will be funneled to educational programs that seek to rejuvenate youths' interest in science disciplines, which have been on the decline in the country's high schools in recent decades."We hope to attract the next generation of kids, to enable them to be engineers and scientists and to make sure that we have more people that can build spaceships in Israel in the future," said Damari.He and the other men behind the initiative also acknowledge that their motives are no less driven by patriotism. Winning the Lunar X has the potential to create national pride and put Israel "on the map as a start-up nation" by accomplishing a feat reserved for superpowers."The moon is something you see every day. I think that for me personally, space exploration is the way to enlist the nation to do something that has not yet been done," said Damari, who started programming aged six and wrote his first computer virus aged 11."It's also about exploring new borders, going the distance. (The project) will leverage Israel's space industry. I'm sure that all the industries that will partner with us will learn a lot and develop new applications, especially for the civilian market," he said.On Thursday, Israeli President Shimon Peres, whose name has become synonymous with the nation's hi-tech industries, honored the trio by unveiling their model at the ceremony held at MABAT -- IAI's missiles and space division near Tel Aviv."More than Israel is leading technology, it is likely to lead Israel. It's the key to our economy ... If they win the prize, and I'm sure they will, it will also reward Israel with the deepest appreciation and the best deterrence," Peres told a crowd of senior executives from local defense industries."I admire your audacity and vision," he complimented the three scientists.Will they realize their ambition? Damari expressed humble optimism, "It's not easy, but certainly possible ... We believe we can win."
