LOS ANGELES, May 29 (Xinhua) -- Nineteen percent of

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, Feb. 8 (Xinhua) -- China would continue expanding its radio and television networks coverage in the country's rural areas in the 2011-2015 period, according to the State Administration of Radio, Film and Television (SARFT).In the five-year period, efforts would focus on ensuring access to radio and TV services in those villages with less than 20 households, the SARFT said in a statement.It noted that China's other villages which had more than 20 households were already covered by the radio and TV networks, thanks to government's continuous efforts in this regard.China's central and local governments poured over 15.7 billion yuan (2.38 billion U.S. dollars) into the upgrading of the radio and TV networks in the country's rural areas in 2006-2010.Official figures indicated that 96.31 percent and 97.23 percent of China's population had access to radio and TV services respectively in 2009. The ratio was 86.02 percent and 87.68 percent respectively in 1997.

BEIJING, May 5 (Xinhua) -- A Chinese official has vowed to take every possible measure to ensure food safety in the country, saying the government has decided to launch national overhauls this year on sectors including milk products, cooking oil, health foods, meat and alcohol.Zhang Yong, director of the executive office of the food safety commission under the State Council, or Cabinet, said in an interview with Xinhua that the food and drinks in these five sectors are consumed in enormous quantities each day and they will do great harm and have an extensive social impact if a problem arises.Through special campaigns to overhaul these five sectors and by solving the most prominent problems, the government aims to accumulate experiences and create administrative systems in a bid to prevent food safety incidents and raise the overall level of food safety, Zhang said.The central government initiated a prolonged and stringent fight against the illegal use of additives in food last month, detailing measures to intensify supervision, upgrade safety limits, and increase penalties for violators.Vice Premier Li Keqiang warned of the great harm from illegal additives in food at a high-profile national meeting last month, promising a "firm attitude, iron-hand measures and more efforts" in dealing with the problem.Zhang Yong admitted "China is in a period when food safety incidents are likely to arise" since the country's food industry is on a fast track for development and a large number of food producers and catering operators are running their businesses in a small-scale or scattered way."It makes it more difficult for the government departments to conduct supervision on food quality and safety," Zhang said."We will take every possible measure to consolidate the feeble foundation to ensure food safety and curb food safety incidents as soon as possible," he said.According to Zhang, the government will also make efforts to improve supervision and emergency handling capabilities, raise the credibility and personnel quality of the involved enterprises, and severely punish violators.The Chinese government made the moves after a series of food safety scandals emerged despite the authorities' efforts to revamp the country's food industry. They included steamed buns dyed with unidentified chemicals, the use of "lean meat powder", also known as clenbuterol, a kind of fat-burning drug, as well as the use of illegal cooking oil known as "gutter oil."
