BEIJING, March 18 (Xinhuanet) --In February this year, Chinese National Geographic magazine published a series of exquisite pictures about Shicheng City (literally, Lion City), and since then, the public's strong interest in the city has been aroused again.The city of nearly 1,339 years of age, situated in east China's Zhejiang Province, has been submerged under Qiandao Lake since 1959 for the construction of the Xin'an River Hydropower Station.International archeologists vividly named the city submerged in water "time capsule." Since it is shielded from the erosion by wind, rain and sun, a city submerged in water comparatively maintains a stable condition, thus making the city a virtual time vessel. Seen from the pictures of Shicheng City, stairs in ancient houses, walls and memorial arches remain the same as they were thousands of years ago.Shicheng City was named after the Wu Shi Mountain (literally, Five Lion Mountain) in the northern part of Sui'an County, Zhejiang. It was once the center of politics, economics and culture of Sui'an County in that area.As written in the "History of Sui'an County," there are all together 265 arches submerged under Qiandao Lake, among which the Jie Xiao Memorial Arch's fine carvings remain well-preserved.According to the restored map of Shicheng, there were five city gates in all directions. You can find one city gate tower on each city gate and all together there are five towers. Besides, six streets in Shicheng City were used to connect every corner of the city as a whole. The typical roads in Shicheng City were stone roads, tidily paved by flagstone and pebbles.

LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.

CANBERRA, April 1 (Xinhua) -- People who share bongs to smoke marijuana may be at risk of contracting pulmonary tuberculosis (TB) , Australian medical researchers warned on Friday.Dr Michael Hayes and Dr Susan Miles from Calvary Mater Hospital in Newcastle of Australia conducted the research, which centered on three recent TB cases in New South Wales.TB is caused by the bacteria Mycobacterium tuberculosis, which can be contracted by breathing in air droplets coughed from an infected person.The research suggested a link between active TB cases and shared bongs, which is the water pipes commonly used in marijuana smoking.According to Dr Hayes, the three young patients were regular or heavy cannabis users, and more recently there has been a fourth person in the region with similar characteristics had been diagnosed with TB.He said although the three initial cases were not related, there was concern about the high rate of positive contacts among people who had shared bongs with the active cases."Smoking marijuana is a cough-provoking activity and it is usually conducted in a confined environment that is conducive to the spread of the organism," he told Australia Associated Press.

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."
