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 11(Xinhuanet)-- People with more fat around their waist, often known as “apple shape”, may not have a greater risk of heart attack than those with fatter bottoms and hips, according to a new study published in Lancet as quotted by media reports Friday.This study funded by the Medical Research Council and British Heart Foundation, reviewed 220,000 individual records from 17 countries and monitored the occurrence of heart attacks or strokes based on body mass index (BMI) versus waist-hip circumference. It found that people with "apple-shaped" obesity were at a higher risk of having heart risks compared to those with general obesity as assessed by their BMI.  This contradicts previous claims that "apple shaped" bodies were three times more likely to suffer heart attacks than those with more generally distributed fat.But experts warn obesity is still bad for the heart, no matter where the fat is, and they argue there is confusion about the best way to measure it. "Regardless of how you measure it, being obese is bad for your heart. This study suggests that measuring your waist is no better than calculating your BMI but it's not time to throw away the tape measure just yet, “Dr Mike Knapton, associate medical director at the British Heart Foundation said."We tend to underestimate our body shape and size, so measuring our waist or checking our BMI are both quick and easy ways we can check our health at home."Besides, he also listed some other heart risk factors that we need to think about too, such as blood pressure, cholesterol, diabetes and smoking.

BEIJING, April 12 (Xinhuanet) -- Doctors may choose riskier treatment with fewer severe side effects for themselves than they'd recommend for their patients, according to a study in the Archives of Internal Medicine Tuesday. In the study, two sets of questions were sent to primary care physicians around the United States. One involved choosing between two types of colon cancer surgery and the other situation involved choosing no treatment for the flu, or choosing a made-up treatment less deadly than the disease but which could cause permanent paralysis. Of 242 physicians who answered the colon cancer questionnaire, 38 percent went with the treatment that carried a higher risk of death but fewer side effects for themselves. By contrast, only a quarter said they would recommend that treatment to their patients.In the flu scenario, 63 percent chose the deadlier option of no treatment for themselves, versus 49 percent recommending it for patients.The findings are important because patients faced with difficult medical decisions often ask their doctors, "What would you do?" The answer reflects the doctors' values -- not necessarily those of the patients.Doctors should know what their patients value most before giving advice, and patients should ask doctors the reasons behind their answers, said study author Dr. Peter Ubel, an internist and behavioral scientist at Duke University.

BEIJING, Jan. 25 (Xinhua) -- China's 11 government departments have jointly released a guideline outlining major measures to lessen noise pollution amid rising noise disputes and complaints, the Ministry of Environmental Protection said Tuesday.The ministry's spokesperson, Tao Detian, said Tuesday the country saw rising complaints about noise pollution, which has caused an increasingly negative impact on the living environment in recent years.The 26-article guideline focuses on addressing noise pollution in fields including industry, construction, traffic and people's daily lives.Further, the regulation bans businesses from using acoustic instruments outdoors to lure customers.Also, heavy noise polluters are banned from entering industrial parks, according to the guideline.Moreover, motor vehicles should strictly observe speed limits, traffic restrictions and use of auto horns around "noise-sensitive buildings" such as hospitals, schools, government organs, scientific research institutions and residential buildings, it said.According to the guideline, government departments would also impose higher fines on noise polluters and collect fees for "discharges of excessive noise," in accordance with law.The newly issued document calls on various government agencies, such as the ministries on environmental protection, science and technology, public security, finance, housing, transportation and railways, to make coordinated efforts to curb pollution.Further, government organs could launch regular inspection campaigns in major cities, it said.According to the guideline, government agencies will set up a system to examine sound-proof qualities of civilian buildings and provide a list of major noise pollution sources by the end of this year.Also, the guideline ordered major cities to establish an automatic noise monitoring system and to equip each city in the country with at least one noise display screen by the end of 2011.

BEIJING, Feb. 26 (Xinhua) -- China's Ministry of Education said Friday that 34.29 million students graduated from the country's higher-learning institutions between 2006 and 2010.Xu Mei, the ministry's spokeswoman, said the number is even more than that of the graduates in the 20 years prior to 2006 combined."During the 11th five-year plan period (2006-2010), higher education has become even more accessible to the general public. Higher-learning institutions provide a strong support of brain power and human resources to the social and economic development," Xu said.The "Outline of China's National Plan for Medium and Long-Term Education Reform and Development (2010-2020)," which was publicized last year, says "the strategic goals to be attained by 2020 are to basically modernize education; shape a learning society; and turn China into a country rich in human resources."
