MOSCOW, May 24 (Xinhua) -- Russia's Soyuz TMA-20 spacecraft with three crew members onboard has landed in Kazakhstan on Tuesday, said the Mission Control Center (MCC) outside Moscow.The spacecraft undocked from the International Space Station early Tuesday, carrying Russian cosmonaut Dmitry Kondratyev, European Space Agency (ESA) astronaut Paolo Nespoli and NASA astronaut Catherine Coleman back to Earth.According to the center, the Soyuz TMA-20 landed in the Kazakh steppe at 6:27 Moscow time (0227 GMT). Some 17 planes and helicopters and several rescue vehicles had conducted search works.Flight engineers Catherine "Cady" Coleman of the U.S. (L) and Italian Paolo Nespoli (R), and Russian cosmonaut and station commander Dmitry Kondratyev are seen after the Soyuz capsule landed, about 150 km (93 miles) southeast of the Kazakh town of Zhezkazgan May 24, 2011. A Russian Soyuz capsule delivered an international trio of astronauts back to Earth on Tuesday after six months on the International Space Station, parachuting through clear skies toward a safe landing on the Kazakh steppe.Deputy head of Federal Medical and Biological Agency Vyacheslav Rogozhkin said Italian astronaut Naspoli had some health problem after landing."Two crew members are fine, the third one has some problems with his vestibular system," Rogozhkin told a press conference after the landing.In December, the Soyuz TMA-20 was launched from the Kazakh Baikonur space center with three crew members.The next launch of manned spacecraft to the ISS was scheduled in early June.

BEIJING, Feb. 5 (Xinhua) -- China's meteorological authority said Saturday that a cold snap would sweep north China over the next few days, bringing down temperatures and carrying gusty winds.Temperatures in some parts of Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and northeast China will drop 4 to 6 degrees Celsius over the weekend, the National Meteorological Center (NMC) said in a statement on its website.In most areas north to the Huaihe River, the temperatures will go down 4 to 6 degrees Celsius, or even 8 to 10 degrees Celsius in some parts of the areas between Monday and Tuesday.The cold front would then move southward to affect more areas in the eastern and southern parts of the country.The NMC said some areas in northern and western Xinjiang Uygur Autonomous Region, the eastern part of Inner Mongolia, Sichuan Basin and most of the northeast China, the western parts of the areas south to the Yangtze River will see light to moderate snow or sleet in the forthcoming three days.Fog continued to shroud south China Saturday, reducing visibility to less than 200 meters in parts of Hunan, Hubei, Jiangxi, Sichuan and Fujian provinces, as well as Chongqing City.

BEIJING, March 28 (Xinhuanet) -- Google Inc. is working with MasterCard Inc. and Citigroup Inc to develop a technology that could make mobile payments, according to media reports Monday.The new technology named "Nexus S Android" is embedded in Android mobile devices and allows customers to make purchases by waving their smartphones in front of a small reader at the checkout counter.Credit-card reader producer VeriFone Systems Inc, also involved in the new payment service, is developing contact-less devices that could allow people to pay with a wave or tap of credit card or a tap of smartphone.To use the service, holders of Citigroup-issued debit and credit cards must activate a mobile-payment application developed for one current model of Android phones. More models will be coming as the technology advances.Besides mobile payment, consumers would also be able to get targeted ads or discount offers, manage credit-card accounts and track spending through an application on their smartphones.Due to the deliberate design of the technology, customers have no need to worry about the security of their payment information. Nick Holland, a mobile-transactions analyst at Yankee Group, said the new technology is more sophisticated than credit cards with a magnetic stripe.With the coming service, Google is aiming to boost its advertising business by offering retailers more data about their customers and help them target ads and discount offers to mobile-device users near their stores.An insider told that Google was not expected to get a cut of the transaction fees.The service is expected to be released this year. Once released, it will broaden the uses of smartphones for everyday activities—from chatting to emailing to shopping.

WELLINGTON, May 27 (Xinhua) -- Eating kiwifruit might be a much better way of getting vitamin C into your system than taking purified vitamin supplements, according to research from New Zealand.Researchers with the University of Otago found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.The study was published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, said a statement from the university.Lead researcher Associate Professor Margreet Vissers said people required vitamin C (ascorbate) in all body tissues and organs to be healthy, but the only source of vitamin C was through food or in purified form, arguably the most commonly consumed vitamin supplement.In the experiment vitamin C-deficient mice were fed the vitamin over a month, either as kiwifruit or as an equivalent amount of pure vitamin C, said the statement.Mice fed the kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and they also retained it for longer, indicating something in the fruit improved absorption and retention."The findings of the mouse trial have important implications for human nutrition," said Vissers."The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue. We are uniquely placed to do that work. "An equivalent human study was underway to determine whether the situation also applied to people, said the statement.The mouse study was funded by the university and kiwifruit marketing firm Zespri.

JERUSALEM, April 12 (Xinhua) -- Israeli-Canadian archaeologist Simcha Jacobovici may have stumbled upon a major archaeological find if his claim of unearthing the nails used to hold Jesus on the cross during his crucifixion are to be believed.Jacobovici maintains that small metal remains dug out of the soil in a cave in a Jerusalem neighborhood are in fact the nails that held Jesus on the cross, the Ha'aretz daily reported Tuesday.The artifacts were found in a cave in the Armon Hanatziv ridge, about 6 km south of the Old City, during the course of a construction work in 1990. The hilly area now contains apartment buildings.During the excavation of the cave, a stone vessel with the name Caiaphas, the name of the High Priest considered responsible for turning Jesus over to the Romans, and two rusty nails, which Jacobovici believes to be the relics, was unearthed.However, officials from the Israeli Antiquities Authority told Xinhua although they regard Jacobovici as a great archaeologist and documentary filmmaker, they do not believe the cave really belongs to the High Priest of the Second Temple period (between 536 BC and 70 AD)."The reason is that during that period of time there were a lot of people with the name Caiaphas," a statement from the Antiquities Authority said, "And for example, it is inconceivable that every gravestone bearing the name Moshe Dayan, which is very common in these parts, should be ascribed to the same personality who played so prominent a role in our recent history."Dayan was an Israeli army general who led his troops to victory in the 1967 war.The authority considers Jacobovici's contention as "fantasy" that should not be considered conclusive, since there is no agreed- upon evidence backing it up.Jacobovici is standing his ground, however, and contends that during the Second Temple Period the name Caiaphas was uncommon, and therefore the tomb must belong to the infamous priest.Jacobovici, a well-known documentary filmmaker, has produced films about the Israeli-Palestinian conflict and human trafficking that earned him two Emmy Awards.He also worked alongside film director James Cameron on the movie Jesus' Lost Tomb.He expects to soon release a movie about the latest finds, entitled Nails on the Cross.
