WASHINGTON, Oct. 4 (Xinhua) -- Green tea may slow down weight gain and serve as another tool in the fight against obesity, according to U.S. Pennsylvania State University food scientists.Obese mice that were fed a compound found in green tea along with a high-fat diet gained weight significantly more slowly than a control group of mice that did not receive the green tea supplement, said Joshua Lambert, assistant professor of food science in agricultural sciences."In this experiment, we see the rate of body weight gain slows down," said Lambert.The researchers, who released their findings on Tuesday in the online version of Obesity, fed two groups of mice a high-fat diet. Mice that were fed Epigallocatechin-3-gallate -- EGCG -- a compound found in most green teas, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG.In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 percent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption, according to Lambert. The green tea did not appear to suppress appetite. Both groups of mice were fed the same amount of high-fat food and could eat at any time."There seems to be two prongs to this," said Lambert. "First, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat."A person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study, according to Lambert. However, he said that recent studies indicate that just drinking a few cups of green tea may help control weight."Human data -- and there's not a lot at this point -- shows that tea drinkers who only consume one or more cups a day will see effects on body weight compared to nonconsumers," said Lambert.

BEIJING, Nov. 20 (Xinhua) -- China on Sunday morning put two satellites into orbit from the Jiuquan Satellite Launch Center in northwest China's Gansu Province.The satellites, Chuangxin 1-03 and Shiyan Satellite 4 were launched on a Long March 2D carrier rocket at 8:15 a.m. Beijing Time, said a Xinhua photographer, who witnessed the whole process.The Chuangxin 1-03, developed by the Chinese Academy of Sciences, will be used to collect and relay water conservancy, hydrological and meteorological data and data for power supply and disaster relief from monitoring stations.The Shiyan Satellite 4 will be used for experiments on space technologies and environment probe. Developed by the Chinese Research Institute of Space Technology, it is the country's fourth technology experiment satellite.The launch was the 151th of China's Long March series of rockets. The Long March-2D is one of the derivations of Long March-2.China started development of modern carrier rockets in 1956, and Long March rockets have become the main carriers for China's satellite launching.

CANBERRA, Dec. 9 (Xinhua) -- Scientists from Australia's University of New England on Friday said they had discovered the remarkably fossil isa metre-long arthropod with excellent vision called anomalocaris from Emu Bay Shale of South Australia.The scientists reported their finding on the anomalocaris in thescience journal Nature this week.It is reported that anomalocaris is a fearsome ancient predator that swam in the Cambrian oceans 500 million years ago. The researchers said the presence of anomalocaris would have driven the development of protective adaptations in prey animals. Such an escalatory 'arms race' would have seen, for instance, the evolution of such adaptations in prey as shells, camouflage and burrowing into sediments. "It has been unbelievably frustrating being able to see eyes like these at fossil sites like the Burgess Shale (in the Canadian Rocky Mountains), but not have any details. It is really refreshing to have our ideas about these animals confirmed at last, " comments Simon Conway Morris, a palaeontologist at the University of Cambridge, the United Kingdom.The research team was led by paleontologist Dr John Paterson, of the University of New England. He said the most surprising discovery of anomalocaris is the huge number of tiny hardened lenses in each eyes."When you consider that a modern housefly, for example, has about 3000 lenses, it's pretty impressive that an animal half a billion years old already has remarkable vision like this," Paterson said in statement."The fact that each eye in anomalocaris would have had over 16, 000 lenses means it would have very, very good resolution."Paterson said the acute vision of Anomalocaris gave it a distinct advantage over competing predators and prey, as many Cambrian animals either had poor vision or were completely blind. Its acute vision rivals or exceeds that of most living insects and was probably comparable to predatory dragonflies today.He said their findings support the idea that compound eyes evolved very early on in arthropod evolution, before the evolution of jointed legs or hardened exoskeletons.The research team hopes they can find the more fossil remains of Cambrian creatures in the Emu Bay Shale.

BEIJING, Nov. 22 (Xinhuanet) -- Underweight patients may have more possibilities of mortality within 30 days of general and vascular surgery compared with mildly obese patients, according to a research published online in Archives of Surgery Tuesday.Researchers at the U.S. National Surgical Quality Improvement Program conducted the research for the years 2005 and 2006, and assessed the contribution of BMI (Body Mass Index) to 189,533 postsurgeries morbidity and mortality by obesity classes.They found that compared with the middle BMI quintile group, patients with BMI value below 23.1, had greater chances for death. For the highest BMI quintile group, higher mortality rate was also observed.However, the researchers also found that obesity may as well be associated with increased mortality for some individual types of surgeries."These individual types of procedures include procedures with which the general surgeon should have definite experience: colorectal resection, colostomy formation, cholecystectomy, hernia repair, mastectomy, and wound debridement," said George J. Stukenborg, PhD, of the University of Virginia inCharlottesvilleand his colleagues.Based on a 30 –day morbidity and mortality risk calculation, the sample patients were categorized into BMI quintile ranges. BMI value of less than 23.1 was considered as lowest, values from 26.3 to 29.6 considered as the middle quintile, and above 35.2 considered as the highest.Factors such as lack of enough data on nonfatal complications and hospital resources, or examining mortality over the 30-day baseline, may cause limitations and inaccuracy to the research and more studies on a wider range of patients in terms of BMI are needed to further confirm the current conclusion, researchers said.

WASHINGTON, Nov. 21 (Xinhua) -- The launch of the Mars Science Laboratory, which contains the car-sized Curiosity rover, has been delayed by a day to Nov. 26, the U.S. National Aeronautics and Space Administration (NASA) announced Monday.The delay will "allow time for the team to remove and replace a flight termination system battery," NASA said in a statement.The launch is now scheduled for 10:02 a.m. (1502 GMT) on Saturday from Cape Canaveral Air Force Station, Florida. The launch window remains open for one hour and 43 minutes.Curiosity is about twice as long and more than five times as heavy as any previous Mars rover. Its 10 science instruments include two for ingesting and analyzing samples of powdered rock delivered by the rover's robotic arm.Scheduled to land on the Mars in August 2012, the one-ton rover will examine Gale Crater during a nearly two-year prime mission. Curiosity will land near the base of a layered mountain three miles (five kilometers) high inside the crater. The rover will investigate whether environmental conditions ever have been favorable for development of microbial life and preserved evidence of those conditions.
