BEIJING, Oct. 26 (Xinhuanet) -- The question, why the first documented supernova was super-sized and grew so fast, has puzzled astronomers for centuries. Now it is solved by US researchers.The supernova, an exploded star, was observed in 185 A.D. and documented as a mysterious "guest star" by Chinese astronomers. It was visible for eight months.Scientists later found the supernova, 8,000 light years away, was a bigger-than-expected supernova remnant. BBC reported that if the infrared light it emits could be seen by human eyes, it would appear to be as large as the full Moon in the sky.Through observations in space telescopes, researchers of a latest study revealed that the explosion took place in a cavity in space, which allowed the star's remains to travel out much faster and farther. The study was published online in the Astrophysical Journal Monday.The supernova was "two to three times bigger than we would expect for a supernova that was witnessed exploding nearly 2,000 years ago. Now, we've been able to finally pinpoint the cause," stated Brian Williams, lead author of the study and an astronomer at North Carolina State University in Raleigh.

SUVA, Jan. 21 (Xinhua) -- Three in four people of the Fiji population are physically inactive causing an increase in health risks, says the country's Ministry of Health.National Advisor on Non-Communicable Disease Dr. Isimeli Tukana said that lifestyle in this Fijian generation has changed a lot, especially for the younger population that have been influenced by technology.Tukana said on Friday many children nowadays are obese and that was of growing concern. That is why the Ministry of Health is working with the Ministry of Education in promoting more physical education in schools and making it compulsory from this school term.Fiji was recently ranked the fourth-most obese nation in the region, according to the Health Ministry.Recent studies in Fiji showed a high incidence of anaemia in children, women and men.Figures released by the ministry said more than 60 percent of the island nation's population is overweight while a significant number are deficient in iron and micronutrients.The figures show that the high rate of premature disability with Non Communicable Diseases (NCD), infection and cancer has taken its toll on the population."The importance of our traditional diets, healthy eating and physical activities is paramount," a ministry statement had said."In the Pacific NCDs have reached epidemic proportions," it said."Nutritional imbalances resulting from not eating local produce instead of canned, processed food contribute to the equation, especially in these times of global economic crisis."Women's Minister Dr. Jiko Luveni has advised mothers in the country this week to stock up on healthy foods for their families.She said having green leafy vegetables was vital and buying fruits for children's snacks instead of salted prepacked ones was the way to keep the family healthy.The National Food and Nutrition Council said Friday that as the school year draws parents should find healthy alternatives for their children.They have urged teachers and parents to include fruits in every child's meal to reduce NCDs.In other countries in the region Tokelau and Nauru's obesity rates stand at 93 percent to 93.5 percent of the population.In American Samoa and Kiribati obesity stands at 81.5 percent of the population, while Marshall Islands at 80.1 percent, Federated States of Micronesia (Pohnpei) at 73.1 percent.

WASHINGTON, Nov. 14 (Xinhua) -- A novel study in twins found that exposure to trichloroethylene (TCE) -- a hazardous organic contaminant found in soil, groundwater, and air -- is significantly associated with increased risk of Parkinson's disease (PD). Possibility of developing this neurodegenerative disease is also linked to perchloroethylene (PERC) and carbon tetrachloride (CCI4) exposure, according to the study appearing in Annals of Neurology on Monday.The National Institute of Neurological Disorders and Stroke estimates that as many as 500,000 Americans have PD and more than 50,000 new cases are diagnosed annually. While there is much debate regarding cause of PD, studies suggest that genetic and environmental factors likely trigger the disease. Several studies have reported that exposure to solvents may increase risk of PD, but research assessing specific agents is limited.The current epidemiological study, led by Samuel Goldman and Caroline Tanner with The Parkinson's Institute in Sunnyvale, California, investigated exposure to TCE, PERC and CCI4 and risk of developing PD. The team interviewed 99 twin pairs in which one twin had PD and one didn't, inquiring about lifetime occupations and hobbies. Lifetime exposures to six specific solvents previously linked to PD in medical literature -- n-hexane, xylene, toluene, CCI4, TCE and PERC -- were inferred for each job or hobby.The findings are the first to report a significant association between TCE exposure and PD -- a more than six-fold increased risk. Researchers also found that exposure to PERC and CCI4 tended toward significant risk of developing the disease. "Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Goldman in a statement.TCE, PERC and CCI4 have been used extensively worldwide, with TCE noted as a common agent in dry-cleaning solutions, adhesives, paints, and carpet cleaners. Despite the U.S. Food and Drug Administration (FDA) banning the use of TCE as a general anesthetic, skin disinfectant, and coffee decaffeinating agent in 1977, it is still widely used today as a degreasing agent. In the U.S., millions of pounds of TCE are still released into the environment each year and it is the most common organic contaminant found in ground water, detected in up to 30 percent of drinking water supplies in the country.In a release issued on Sept. 28, 2011, the Environmental Protection Agency announced that TCE is carcinogenic to humans.

BEIJING, Jan. 21 (Xinhua) -- The State Grid Corporation of China (SGCC), the country's largest electric power transmission and distribution company, said Saturday that the power supply will be sufficient during the upcoming Spring Festival holiday.Thermal power plants currently have 89.34 million tonnes of coal, which is enough for 20 days of power generation.Meanwhile, the country's electricity consumption is expected to fall by 40 percent during the holiday which lasts from Jan. 22 to Jan. 28, as many factories suspend production during the period, SGCC said.The company said it will keep a close eye on the cold weather, strengthen inspections and maintenance of high-voltage grids, and take precautions to minimize the impact of snow and freezing rain on power transmission.

SAN FRANCISCO, Nov. 3 (Xinhua) -- Computer chipmaker Advanced Micro Devices Inc. (AMD) on Thursday said it plans to cut its global workforce by about 10 percent in a move to reduce operational costs.The layoff will occur across all functions globally and is expected to be substantially completed by the end of the first quarter of 2012, the company said.The cuts will amount to about 1,400 jobs, according to estimates by analysts.Combined with implementing efficiencies across the company's operations, AMD expected that the workforce reduction will result in operational savings of more than 200 million U.S. dollars in 2012."Reducing our cost structure and focusing our global workforce on key growth opportunities will strengthen AMD's competitiveness and allow us to aggressively pursue a balanced set of strategic activities designed to accelerate future growth," Rory Read, AMD's chief executive officer, said in a statement.As the world's second largest maker of processors for computers, AMD has been suffering from the slowdown of global PC market and is seen as slow to move into new mobile device market.The operational savings will help accelerate the company's future growth in lower power, emerging markets and in the cloud computing field, AMD said.
