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."

WASHINGTON, Dec. 2 (Xinhua) -- The U.S. Justice Department Friday approved Google's 400 million dollar acquisition of Admeld, a company that provides an online advertising platform for publishers.The Justice Department concluded that it was "not likely to substantially lessen competition in the sale of display advertising."Google operates the largest Internet search engine in the world and one of the largest display advertising platforms. It had revenues of about 29 billion dollars in 2010, most of which came from ads revenue.Admeld, with annual revenue of 30 million dollars, offers technology services to Internet publishers that help them boost revenue by optimizing ads display from hundreds of sources.Google is expected to grab 9.3 percent of online display advertising spending in the U.S. this year, up from 8.6 percent last year, making it the No. 3 provider, according to the digital intelligence company Emarketer.The No. 1 position will be taken by Facebook with its share increased to 16 percent up from 12 percent a year ago, while Yahoo! will slip slightly to 13 percent, said Emarketer.

BEIJING, Jan. 10 (Xinhuanet) -- Conflicts among hundreds of scalpers raring to stock up on the new iPhone 4S are casting a shadow over the gadget's launch on the Chinese mainland on Friday.Over the weekend, scalpers from two groups bickered and shoved each other when standing in line to purchase iPhone 4 at Apple's Sanlitun store, said witnesses.Workers from two Apple stores in Beijing told China Daily the stores have not started online bookings for the iPhone 4S so far."More than 1,000 of us have gathered to buy all the available iPhone 4 this morning," said a scalper hawking the phone outside the Sanlitun store on Sunday."We'll come again on Friday for iPhone 4S. You'll have no hope of getting an iPhone 4 or 4S from the store, but only from us."The scalpers are asking 4,450 yuan (705 U.S. dollars) for an 8-gigabyte iPhone 4, and 5,450 yuan for a smuggled iPhone 4S. Apple sells an 8-gigabyte iPhone 4 on the mainland for 3,988 yuan.An Apple employee at the Sanlitun store who declined to give her name told China Daily on Monday that the store was aware the scalpers may be planning to besiege the iPhone 4S launch, and the store has prepared for that.Calls to the public relations office of Apple China went straight to voice mail.Police of the Sanlitun police station refused China Daily's interview request.An officer of the property management company of the Sanlitun Village shopping mall, where the store is located, said on Sunday they had not been informed about the weekend fracas outside of the Apple store.But on Monday afternoon, staff members of the company dispersed the scalpers by sealing off part of the store's entrance.Workers at the Sanlitun store and property management staff confirmed two groups of scalpers fought on Saturday afternoon and Sunday when jumping the line or stopping each other to pay to get an iPhone 4.Since October 2010, Apple has ceased direct sales of iPhone 4 at its retail outlets in Beijing and Shanghai and is only accepting online orders or reservations and schedules pick-up at stores to curb rampant scalping.But the registration system for reserve and pick-up has become "momentarily unavailable because of heavy traffic volume" in recent days, said Apple's website.A scalper in his 30s outside the Sanlitun store boasted they had "hacked" Apple's reservation page. He described himself an "unofficial salesman" of Apple.Defending the actions of scalpers that lead to consumers having to pay more, he said "it's not our fault but Apple's, because they put too few products in the mainland market."This is not the first time scalpers have targeted Apple products.Two men and two women suffered minor injuries outside the Sanlitun store during a clash between a worker and angry customers as Apple fans waited to buy iPhone 4 and the newly released iPad 2 in May 2011.According to reports, the incident started when a worker confronted an alleged scalper for jumping the line. This led to a verbal conflict in which the alleged scalper was thrown against the corner of an outside wall, causing injuries to his face and wrist

SAN FRANCISCO, Dec. 8 (Xinhua) -- Twitter on Thursday started to roll out a major redesign of its interface in hopes of simplifying users' experience, as well as new brand pages to strengthen its relationship with advertisers.During a press conference at its new headquarters in San Francisco, Twitter Chief Executive Officer Dick Costolo and co- founder Jack Dorsey unveiled a whole new look of the social networking and microblogging service.According to an introduction video, the new homepage features profile on the left and the timeline on the right, which are flipped from the current positions and take less space than they used to.Three new buttons were also introduced as "Home," "Connect" and "Discover." "Connect" shows users who has mentioned them and suggests some accounts they might want to follow. "When you use Discover, you'll see results reflecting your interests -- based on your current location, what you follow and what's happening in the world," said Twitter.The overhauled interface is only available to a small group of users at first and will be rolled out to all users over the coming months. It will also remain consistent across Twitter's official mobile apps. Twitter has launched a page fly.twitter.com to explain all the changes.Along with the introduction of the redesign, Twitter also announced new brand pages on its platform. A total of 21 brand partners will be included in the initial launch, such as American Express, Best Buy, Bing, Coca-Cola, HP, Disney and Nike.Analysts said Twitter has ambitions to compete with similar brand pages from Facebook and Google+. According to eMarketer, Twitter's global advertising revenue is expected to reach 139.5 million U.S. dollars this year and approach 400 million dollars in 2013.

WASHINGTON, Dec. 5 (Xinhua) -- A recent study found that low vitamin D levels are significantly more prevalent in obese children and are associated with risk factors for type 2 diabetes. This study was accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism.High rates of vitamin D deficiency have been found in obese populations and past studies have linked low vitamin D levels to cardiovascular disease and type 2 diabetes. But the mechanisms by which obesity and its comorbidities are related to vitamin D deficiency are not fully known.This new study examined associations between vitamin D levels and dietary habits in obese children, and tested whether there were correlations between vitamin D levels and markers of abnormal glucose metabolism and blood pressure.In this study, researchers measured vitamin D levels, blood sugar levels, serum insulin, body mass index (BMI) and blood pressure in 411 obese subjects and 87 control non-overweight subjects. Study participants were also asked to provide dietary information including daily intake of soda, juice and milk, average daily fruit and vegetable intake, and whether or not they routinely skipped breakfast. BMI is a measurement of body fat calculated from weight and height."Our study found that obese children with lower vitamin D levels had higher degrees of insulin resistance," said Micah Olson, of The University of Texas Southwestern Medical Center in Dallas and lead author of the study. "Although our study cannot prove causation, it does suggest that low vitamin D levels may play a role in the development of type 2 diabetes.""Poor dietary habits such as skipping breakfast and increased soda and juice intake were associated with the lower vitamin D levels seen in obese children," said Olson. "Future studies are needed to determine the clinical significance of lower vitamin D levels in obese children ... and whether treatment with vitamin D can improve primary clinical endpoints such as insulin resistance.
