BEIJING, Jan. 30 (Xinhua) -- A total of 248 people were arrested in China last year for involvement in food safety cases, food safety authorities said Sunday.The country dealt with 130,000 cases involving food safety last year, including 115 criminal cases, according to a statement of the National Food Safety Regulating Work Office.The cases touched upon such areas as production of edible agricultural produce, food production, food circulation, catering services and food exports and imports,"No major incident occurred last year, and the overall food safety situation maintained stable," said the statement.Last year also saw a nationwide crackdown on "gutter oil", usually made from discarded kitchen waste that has been refined, after media reports that it was commonly used by small restaurants.Since July when the State Council, or Cabinet, ordered the eradication of "gutter oil", 165.7 tons of edible oil has been confirmed to have been disqualified and produced by unknown sources.Chinese authorities since July last year have also cracked down on the use of undisposed tainted milk powder produced before the melamine scandal of 2008.About 2,132 tonnes of melamine-tainted milk powder was seized in the latest crackdown, the statement said.A total of 191 officials were punished for failing to do their duty in food safety enforcement, with 26 of them fired, it said.In July last year, Dongyuan milk powder, produced in west China's Qinghai Province, was found to contain excessive levels of melamine, a toxic chemical normally used in the manufacturing of plastics, which triggered the nationwide crackdown.It is the latest blitz on tainted milk products since 2008 when melamine-tainted milk powder killed at least six infants and sickened 300,000 children across the country.

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.

LOS ANGELES, April 17 (Xinhua) -- Global warming will melt all the ice in the Arctic Ocean every summer, raising earth temperatures even further, researchers at the University of California-Los Angeles (UCLA) warned.The findings, available online Sunday in the April issue of Earth and Planetary Science Letters, a leading journal in geoscience, were based on analysis of the fossilized remains of four-million-year-old mollusks, they said.Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today, the researchers said.And these ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months, according to the researchers.Such balmy polar weather would certainly melt all the ice in the Arctic Ocean every summer, said Aradhna Tripani, an assistant professor at the UCLA's departments of Earth and space sciences."Our data from the early Pliocene, when carbon dioxide levels remained close to modern levels for thousands of years, may indicate how warm the planet will eventually become if carbon dioxide levels are stabilized at the current value of 400 parts per million," she said.The earth's temperature was raised five to nine degrees Fahrenheit merely by the absence of year-round Arctic ice, according to Tripani.The results of the study lend support to assertions made by climate modelers that summertime sea ice may be eliminated in the next 50 to 100 years, which would have far-reaching consequences for Earth's climate, she said."The Intergovernmental Panel on Climate Change identifies the early Pliocene as the best geological analog for climate change in the 21st century and beyond," said Tripati. "The climate-modeling community hopes to use the early Pliocene as a benchmark for testing models used for forecasting future climate change."

BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.

BEIJING, March 6 (Xinhua) -- China aims to "basically eradicate poverty" by 2020 while greatly raise its poverty line, in order to help more people in need, Chinese Premier Wen Jiabao said here Sunday.The State Council is drafting a new ten-year poverty-reduction plan (2011-2020), in which the current poverty line of 1,196 yuan per year (about 0.5 U.S. dollars a day) will be greatly raised, Wen told a panel meeting of the ongoing session of the National People's Congress (NPC).The nation will intensify its poverty alleviation efforts through aids and development, focusing on large areas of destitute population, he said to a group of NPC deputies from Gansu, one of the poorest regions in China.According to the United Nations' standard of one dollar per person each day, China still has 150 million people under the poverty line.Wen said lack of water was the bottleneck for Gansu's social-economic development, urging the province to expand the use of water conservancy technology.Wen also urged the province to coordinate economic development with environmental protection, and reverse environmental degradation in Dunhuang, a historical city with world cultural heritage threatened by decertification.
