BEIJING, Oct. 2 (Xinhua) -- Chinese archeologists have found evidence indicating that the mysterious ancient city of Loulan (Kroraina) once had highly-developed agricultural systems.Scientists from the Institute of Geology and Geophysics under the Chinese Academy of Sciences conducted remote sensing procedures, field investigations and sample testing in the area and found that there were once large tracts of farmlands in Loulan.The farmland featured regular and straight circumferences stretching for 200 to 1,000 meters as well as irrigation ditches running throughout, said Qin Xiaoguang, a member of the research team.Moreover, researchers found grain particles in the area's ground surface, which are very likely to be remains of crop plants, Qin said.These findings show that irrigation farming had been practiced in Loulan for at least 100 years, Qin said.Qin said they also found canal remains measuring 10 to 20 meters wide and 1.6 meters deep in the Loulan relics, indicating that the city, which is suspected of perishing in drought, was once rich in water resources.The ancient city was a pivotal stop along the famous Silk Road, but mysteriously disappeared around the third century AD.Previous historical records suggested that Loulan's economy was sustained by widespread agricultural activity, but no remains or other evidence had been found before the most recent discoveries.

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.

BEIJING, Dec. 9 (Xinhua) -- Beijing has seen a declining trend in newly built ordinary apartments in the past 11 months of this year, said a report released by the Beijing Real Estate Association on Friday.That average price of 13,914 yuan (about 2,194.23 U.S. dollars) per square meter from January to November went down 6.3 percent from the yearly average housing price of 14,847 yuan per square meter in 2010, also the target set by the municipal government in attempting to control soaring house prices, said the report.It is expected that the real-estate market in Beijing will maintain the gradually declining trend. And the target of "a stable yearly price with a slight decline" will be smoothly reached, said Chen Zhi, secretary-general of the association.In November, first-time home buyers took up about 90 percent of housing consumers for the ninth month in a row, which means the government's measures to crowd out investing or speculative buying and meet the demands of conventional buyers are working, the report said.This year the government has repeatedly stressed its efforts to contain the runaway property market, through measures including tighter monetary policies, higher down payments, a ban on third-home purchases, price control targets and a trial property tax.

BEIJING, Nov. 7 (Xinhuanet) -- A huge asteroid will pass closer to Earth than the moon on Tuesday, but experts say there is no cause for alarm.Asteroid 2005 YU 55 will pass about 300-thousand kilometers from the earth. The giant space rock is about 400 meters in diameter. The close encounter will occur at 23:28 Greenwich Mean Time. Computer models showing the asteroid’s path for the next 100 years show there is no chance it will hit Earth during that time.Previous studies show the asteroid is what is called a C-type asteroid that is likely made of carbon-based materials and some silicate rock.

WELLINGTON, Oct. 26 (Xinhua) -- New Zealand's geothermal scientists will be collaborating with the world's leading geothermal researchers after the country joins an elite international group next month.New Zealand would be admitted to the International Partnership for Geothermal Technology (IPGT) in Melbourne, Australia, on Nov. 16, Science and Innovation Minister Wayne Mapp announced Wednesday."Geothermal energy is one of our most important renewable energy resources with huge potential for growth," said Mapp."This recognition of our geothermal research programs will allow our scientists to collaborate with an elite group of researchers in the United States, Australia, Switzerland and Iceland."Scientists from New Zealand research organizations were committed to finding new ways to harness the country's extensive geothermal fields, said Mapp."Innovation and clean energy is a big part of enabling New Zealand to grow the economy," said Mapp."This new international partnership will help keep us at the forefront of technology developments such as enhanced geothermal systems."Established in 2008, the IPGT seeks to develop advanced, cost- effective geothermal energy technologies through international research co-operation.New Zealand's geothermal electricity generation rose by 21 percent last year and accounted for 13 percent of total electricity generation, its highest recorded level.The government is aiming to expand geothermal energy with three large geothermal projects in the pipeline by 2020.The country's biggest geothermal project is to be Contact Energy's 250-megawatt Tauhara II geothermal project.The project, being developed northeast of the central North Island town of Taupo, is expected to produce enough electricity to meet the needs of around 270,000 homes when it becomes fully operational in 2015.
