BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.

SAN FRANCISCO, Nov. 12 (Xinhua) -- Apple has unveiled a worldwide replacement program for the first-generation iPod nano music player due to overheating battery issues, telling owners to stop using the product and get it replaced for free."Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Affected iPod nanos were sold between September 2005 and December 2006," said Apple in a notice posted late Friday on the support section of its official website.The company said the issue has been traced to a single battery supplier that produced batteries with a manufacturing defect. Since the product is five or six years old now, the likelihood of an incident increases.Owners of iPod nano can check the serial number on the back of the product to see if it is eligible for replacement. Apple promises a replacement unit about six weeks after the company received the affected one.The overheating battery issues of the first generation iPod nano have been known for years. In 2008, Japan's Ministry of Economy, Trade and Industry launched an investigation into Apple after dozens of iPod overheating cases were reported, including several incidents of iPod nanos toasting to the point of catching fire and causing minor burns to owners.Last August, a commuter train in Tokyo was delayed during rush hour when passengers complained of a strong burning smell from an overheating iPod nano that had burst apart.The portable music player also cost Apple a 22.5 million-U.S. dollar settlement in 2009 when a class action lawsuit in California alleged iPod nano is prone to scratches and its alleged defects were not disclosed by the company.

CANBERRA, Dec. 9 (Xinhua) -- Scientists from Australia's University of New England on Friday said they had discovered the remarkably fossil isa metre-long arthropod with excellent vision called anomalocaris from Emu Bay Shale of South Australia.The scientists reported their finding on the anomalocaris in thescience journal Nature this week.It is reported that anomalocaris is a fearsome ancient predator that swam in the Cambrian oceans 500 million years ago. The researchers said the presence of anomalocaris would have driven the development of protective adaptations in prey animals. Such an escalatory 'arms race' would have seen, for instance, the evolution of such adaptations in prey as shells, camouflage and burrowing into sediments. "It has been unbelievably frustrating being able to see eyes like these at fossil sites like the Burgess Shale (in the Canadian Rocky Mountains), but not have any details. It is really refreshing to have our ideas about these animals confirmed at last, " comments Simon Conway Morris, a palaeontologist at the University of Cambridge, the United Kingdom.The research team was led by paleontologist Dr John Paterson, of the University of New England. He said the most surprising discovery of anomalocaris is the huge number of tiny hardened lenses in each eyes."When you consider that a modern housefly, for example, has about 3000 lenses, it's pretty impressive that an animal half a billion years old already has remarkable vision like this," Paterson said in statement."The fact that each eye in anomalocaris would have had over 16, 000 lenses means it would have very, very good resolution."Paterson said the acute vision of Anomalocaris gave it a distinct advantage over competing predators and prey, as many Cambrian animals either had poor vision or were completely blind. Its acute vision rivals or exceeds that of most living insects and was probably comparable to predatory dragonflies today.He said their findings support the idea that compound eyes evolved very early on in arthropod evolution, before the evolution of jointed legs or hardened exoskeletons.The research team hopes they can find the more fossil remains of Cambrian creatures in the Emu Bay Shale.

BEIJING, Jan. 24 (Xinhua) -- China's meteorological authority said Tuesday that the country's northern regions will continue to have sunny weather for the coming 24 hours, while the south will see subdued rain and snow.Temperatures in most parts of the country are expected to rebound slightly, the National Meteorological Center said in a statement on its website.But the lowest temperatures in the areas south of the Yangtze River will remain around zero degree Celsius, the center said.Meanwhile, rain and snow will subdue in most parts of the southern regions over the next three days, although freezing rain is forecast to hit Guizhou and Hunan provinces, according to the statement.

BEIJING, Dec. 18 (Xinhua) -- China's economic diplomacy will face growing challenges in the form of trade and exchange rate disputes, as well as the task of protecting overseas investment interests, over the next few years, experts said on Sunday.Next year will be an election year for the Unite States and France, and there is an increasing possibility for the two countries to use the "China threat" as an excuse for not dealing with their own economic issues, which will put Chinese diplomacy under pressure, said Ding Yifan, deputy director of the Institute of World Development of the Development Research Center of the State Council at a seminar on Chinese diplomacy.During the first half of 2012, several countries will remain in a grave debt crisis and may even see their crises deepen, Ding said, adding that this situation may create friction between China, the United States and Europe.Additionally, protecting China's growing overseas investments will pose new challenges for the country's diplomacy, Ding said.Chen Fengying, director of the Institute of World Economic Studies under the China Institutes of Contemporary International Relations, agreed that the protection of China's overseas investment interests will be an important task for Chinese diplomacy.During the past three decades, China has invested in more than 170 countries and regions, with outbound direct foreign investment topping 170 billion U.S. dollars.In the past 30 years, China has been focused on "bringing in" foreign investment; it may do more to facilitate its "going out" in the future, Chen said.Chinese economic diplomacy will serve the country's economic construction and the protection of its overseas interests, national interests and security, Chen said, adding that China's position in the world is closely related to its economic diplomacy.Chen said China has made several achievements in international economic governance, reflected by China's growing influence in the international arena and the posts held by Chinese officials in important international organizations.
