LOS ANGELES, March 18 (Xinhua) -- The moon will move closer to Earth than it has been in more than 18 years Saturday night, space. com reported on Friday.On Saturday afternoon at 3 p.m. Eastern Daylight Time (1900 MGT) , the "supermoon", as dubbed by some observers, will arrive at its closest point to the Earth in 2011: a distance of 221,565 miles ( 356,575 kilometers) away, and only 50 minutes earlier, the moon will officially be full, the report said.At its peak, the supermoon may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting, said the report.Yet to the casual observer, it may be hard to tell the difference, according to the report.Scientists say it is a fluke of orbital mechanics that brings the moon closer to Earth.The supermoon will not cause natural disasters, such as the Japan earthquake, NASA scientists say.In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee - the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions, the report said.

BEIJING, April 14 (Xinhuanet) -- The discovery of a sharp-toothed dinosaur fossil in New Mexico, the United States, may bridge a gap in the evolution of the species, researchers said in Wednesday's journal Proceedings of the Royal Society B.Researchers from the Smithsonian Institution unearthed the dinosaur skull and neck vertebrae in Abiquiu, New Mexico, where it had remained buried for around 230 million years. The short snout and slanting front teeth of the find — Daemonosaurus chauliodus — had never before been seen in a Triassic era dinosaur, said Hans-Dieter Sues of the Smithsonian's National Museum of Natural History.Sues, curator of vertebrate paleontology at the museum, said the discovery helps fill the evolutionary gap between the dinosaurs that lived in what is now Argentina and Brazil about 230 million years ago and the later theropods like the famous Tyrannosaurus rex."Various features of the skull and neck in Daemonosaurus indicate that it was intermediate between the earliest known predatory dinosaurs from South America and more advanced theropod dinosaurs," said Sues."One such feature is the presence of cavities on some of the neck vertebrae related to the structure of the respiratory system," he added.The discovery suggests that there is still much to be learned about the early evolution of dinosaurs."The continued exploration of even well-studied regions like the American Southwest will still yield remarkable new fossil finds," Sues said.

BEIJING, March 24 (Xinhuanet) -- A new study has found that Actos, a medicine treats onset diabetes, could also reduce the diabetes risk in people with prediabetes.The study, which was published Wednesday in New England Journal of Medicine, followed 602 prediabetics whose obesity, ethnicity, family history and other factors put them at high risk of developing diabetes.The research findings showed that Actos, generically known as pioglitazone, reduced the odds of developing Type 2 diabetes by 72 percent in people with prediabetes.Only 2.1 percent of those who took Actos developed diabetes each year over the three years of the study, compared with 7.6 percent of those who took a placebo.Lead author of the study Ralph DeFronzo said, "The 72 percent reduction is the largest decrease in the conversion rate of pre-diabetes to (Type 2) diabetes that has ever been demonstrated by any intervention, be it diet, exercise or medication."However, Actos can have significant side effects, including water retention, moderate weight gain, and increased risk of bone fractures.

XI'AN, March 31 (Xinhua) -- Archeologists in the northwestern Shaanxi Province confirmed Thursday, after weeks of lab work, that the bones they found in a bronze cooking vessel from a 2,400-year-old tomb belonged to a male dog under a year old.Altogether 37 bones were found in the cooking vessel, which was unearthed in November 2010 from a tomb near the Xianyang International Airport in the suburbs of Xi'an, said Liu Daiyun, a researcher with the Shaanxi Provincial Archeological Institute."When we opened the 20-cm tall cooking vessel, we were shocked to find bones and soup inside," said Liu.The bones and soup had all turned greenish, similar in color to the bronze container, he said.Cooking vessels were a typical offering Chinese once presented to their deceased ancestors, said Liu.The custom became prevalent around the Warring States Period (475 - 221 BC), the time Liu and his colleagues believed this dog stew was offered.Hu Songmei, a researcher who did most of the lab work to identify the bones, said they found the bones were "strikingly similar" to four complete sets of canine skeletons preserved at the institute's lab.The newly found bones, however, were smaller, indicating the dog was just a pup, said Hu.Hu said further lab work was needed to tell the exact species of the canine. "Dogs were domesticated by humans at least 10,000 years ago, but the early dog species that evolved from wild wolves could be very different from today's pet dogs."Besides the dog bones, experts also found a wine-like liquid in another airtight kitchen ware from the same tomb. "Whoever the tomb owner was, he must have loved liquor and meat, so his sons wished he could still enjoy the feast in his grave."

SAN FRANCISCO, April 4 (Xinhua) -- Google Inc. on Monday announced that it is bidding for patent portfolio of Nortel Networks in the bankruptcy auction for the Canadian telecommunications equipment maker.In a press release, the Toronto-based Nortel said Google has agreed to buy all of its remaining patents and patent applications for 900 million U.S. dollars in cash.Nortel, which filed for bankruptcy protection in 2009, expects the auction to be held in June this year, pending Canadian and U.S. court approvals.Nortel has selected Google's bid as the "stalking-horse bid," or the starting point against which others will bid prior to the auction.The agreement with Google includes the planned sale of about 6, 000 Nortel patents and patent applications spanning wireless, wireless 4G, data networking, optical, voice, Internet, service provider and semiconductors.According to Nortel, the patent portfolio touches nearly every aspect of telecommunications and additional markets, including Internet search and social networking."This is an unprecedented opportunity to acquire one of the most extensive and compelling patent portfolios to ever come on the market," George Riedel, Nortel's chief strategy officer, said in a statement.Google argued that the bid would help protect it from patent litigation and foster innovation.The technology industry has recently seen an explosion in patent litigation, often involving low-quality software patents, which threatens to stifle innovation, Kent Walker, Google's general counsel, said in a blog post, believing the best defense against such litigation is to have a "formidable patent portfolio. ""So after a lot of thought, we've decided to bid for Nortel's patent portfolio in the company's bankruptcy auction," he said."If successful, we hope this portfolio will not only create a disincentive for others to sue Google, but also help us, our partners and the open source community -- which is integrally involved in projects like Android and Chrome -- continue to innovate," Walker noted.
