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.

HEFEI, Feb. 2 (Xinhua) -- Chinese Premier Wen Jiabao has visited farmers and workers in Dabieshan Mountain area, an old revolutionary base in east China's Anhui Province, to extend new year greetings ahead of the Spring Festival, which falls on Thursday.On Tuesday, Wen went to the area's Jinzhai County, once an important Red Army revolutionary base, to learn about the local economic and social development situation.He visited Zhaoyuan Village and called in on farmer Zhao Mengqi. Wen chatted with Zhao, asking about his family's income and their preparations for the lunar new year.Zhao works as a migrant worker in Wujiang City, an economically-developed part of Jiangsu Province. His son and daughter-in-law work in Shanghai. They returned home on the eve of the Spring Festival."With the income we earn working in cities and what we earn growing crops, our family income has increased and we have rebuilt and renovated our house," Zhao told Premier Wen. A paved road now allows buses to reach the village, Zhao added.Wen said, "Only when the people living in old revolutionary bases live better lives can we feel relieved."At farmer Zhao Kongying's home, Wen joined the family in making "yuanzi," a glutinous rice ball traditionally eaten during the Spring Festival.Wen later went to Hetang Village. There he visited villager Yu Shuhua's home and urged the local government to provide more help to needy people to ensure they have a happy lunar new year.At dinner time, he went to villager Zhang Jiasheng's home, joining the family to prepare dinner. He wore an apron and made a soup for the family.During the dinner, Zhang told Wen the village is rich with chestnuts, tea and traditional Chinese medicine, adding that tourism is also a source of income for the village.Wen said help and support for the old revolutionary base should be boosted, so that local people can lead happier lives.Wen also extended new year greetings to workers at the Meishan hydropower station in Jinzhai County.At retired worker Wan Benrong's home, Wen asked about the family's living conditions and their preparations for the lunar new year.After being told the couple received an extra 140 yuan each of monthly pension this year, Wen said the government has increased the basic pension for retired workers seven times since 2005."Our objective is to make you feel secure," Wen said.

WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."
