JINAN, May 14 (Xinhua) -- Chinese scientists said Saturday that they have found a new species of giant theropod dinosaur in the eastern province of Shandong.The new species, described as a close relative of Tyrannosaurus rex (T. rex), has been named "Zhuchengtyrannus magnus". Paleontological experts found it has unique upper jawbones after examining the skull and jawbones discovered in the city of Zhucheng.It was estimated to be about 11 meters long and 4 meters tall, weighing close to 7 tonnes."We discovered two kinds of tyrannosaurus fossils here and the identity of the other one still remains unclear," said Xu Xing, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences."We've named the new genus Zhuchengtyrannus magnus, which means the 'Tyrant from Zhucheng' because the bones were found in Zhucheng," Xu said.The bones were a few centimeters smaller than the similar bones in the largest T. Rex specimen, so there was no doubt that Zhuchengtyrannus was a huge tyrannosaur, Xu said.According to Xu, Zhuchengtyrannus magnus belonged to a specialized group of gigantic theropods called tyrannosaurines which existed in North America and eastern Asia during the Late Cretaceous Period that dated back about 65 to 99 million years.All tyrannosaurs were carnivorous, bipedal animals that generally had small arms and large skulls. Among the tyrannosaurs, the tyrannosaurines were the largest and characterized by having just two fingers on each hand and large powerful jaws to deliver a bone crushing bite. They were likely both predators and scavengers.The fossil quarry in Zhucheng contains one of the largest concentrations of dinosaur bones in the world. At least 10 dinosaur species have been found in three rounds of excavations since the 1960s, including Tyrannosaurus and Hadrosaurs.

LOS ANGELES, March 4 (Xinhua) -- The California Department of Public Health on Friday announced a recall of hazelnuts which might be contaminated by E. coli bacteria.The department said it ordered the recall after seven people fell sick with E. coli bacteria from eating tainted hazelnuts.The seven illnesses include one in Michigan, three in Minnesota and three in Wisconsin, said Dr. Howard Backer, interim director of the department.The hazelnuts were distributed by DeFranco & Sons, a Los Angeles company, said the department.After being notified of the contamination, the company is voluntarily recalling the nuts, the department said.The hazelnuts affected by the recall were sold under the brand names Sunripe, George Packing, Firestone Farms and Northwest Hazelnut and were distributed nationwide from Nov. 2 to Dec. 22, according to the department.The 50-pound bags of hazelnuts and mixed nuts with hazelnuts may have been repacked or sold from bulk containers, the department said, adding people who had bought the hazelnuts should not eat them.Consumers should check with retailers to determine if their nuts are subject to the recall, and if they are, should discard them, the department added.People who develop symptoms after consuming hazelnuts should seek immediate medical attention, the department suggested.E. coli may cause symptoms that include bloody diarrhea, stomach cramps and dehydration. In extreme cases, patients can suffer potentially life-threatening complication known as hemolytic uremic syndrome, which includes kidney failure.Young children and the elderly are the most vulnerable to the risk.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.

SAN FRANCISCO, April 5 (Xinhua) -- Apple Inc.'s iPad 2 has topped the ratings by Consumer Reports, an influential U.S. magazine for product reviews, in the latest tests of the 10 most- promising tablet computers.According to the ratings released on Tuesday, the Apple iPad 2 with Wi-Fi plus 3G (32G), which is priced at 730 U.S. dollars, topped the ratings, scoring "excellent" in nearly every category.Besides several models from Apple, other brands tested include Archos, Dell, Motorola, Samsung and Viewsonic. Each tablet was evaluated on 17 criteria, including touch-screen responsiveness, versatility, portability, screen glare and ease of use."So far, Apple is leading the tablet market in both quality and price, which is unusual for a company whose products are usually premium priced," Paul Reynolds, electronics editor at Consumer Reports, said in a statement.The Motorola Xoom, whose price is 800 dollars, stood out as the iPad 2's main rival. It boasts several features that the iPad lacks, including a built-in memory card reader and support for the Flash videos.The first-generation iPad, priced at 580 dollars, also outscored many of the other models tested but tied with the Motorola Xoom, according to tests by Consumer Reports.

MOSCOW, Feb. 9 (Xinhua) -- China's steady economic rise causes both high hopes and anxiety among world leaders, but a Russian expert believes China's peaceful development is an opportunity for the entire world.Yakov Berger of the Far East Institute of the Russian Academy of Sciences told Xinhua that China's policy of peaceful development is a strategic choice, aimed at long-term and sustainable growth."China overcame the global financial crisis, decreased poverty, and increased people's wealth," Berger said."Still, many important tasks for China remain to be fulfilled and first of all, modernization, industrialization and urbanization. This is why China needs strong and long-lasting peace," he said.Berger said China's policy of peaceful development has already won support from the majority of countries, so they are willing to cooperate with the world's most powerful developing nation."China's peaceful development gives chance to all people in the world, as China became the main engine of the global economic development. Many developed countries are gravitated to China because they depend on Chinese supplies and the Chinese market," Berger said.However, although some countries are aware that China's sustainable growth requires peace and stability, some eye China's growing influence as negative, the professor said.Berger said that Beijing tries to persuade Washington that China's rise does not threaten American security. The question, then, is to what degree is the U.S. ready to accept the new reality, Berger said.Berger cited two main reasons why some Western politicians don't trust Beijing."First, this is a natural response from the people who got used to a certain world order," he said, "Such an order implies the existence of the so-called 'golden billion' people who have access to all of civilization's benefits while the other five billion can't make ends meet."Berger said that when China attempts to achieve the same living standards, that induces some fears based on the notion that the Earth resources are limited.Berger believed the second reason is xenophobia and racism, which generates talk about the "Chinese threat.""But they talked about the 'China threat' even in times when China used to be an underdeveloped nation," Berger noted.
