WUHAN, Oct. 8 (Xinhua) -- A museum that honors the 1911 Revolution, also known as the Xinhai Revolution, reopened Saturday after renovation to commemorate the centenary of the uprising at Wuchang in central Hubei province.More than 200 items that illustrate the revolution, such as photos, telegraphs, models and and simulative historic scenes, are on display.Located near the famous Yellow Crane Tower, the museum was once the headquarters of the revolutionary army.The movement's leader, Sun Yat-sen, overturned the ruling Qing Dynasty (1644-1911) after the revolution on Oct. 10, 1911 and founded the Republic of China in 1912.Commemorative gatherings were also held in provinces of Guangdong, where Sun was born, and Jiangsu, where the capital of the Republic of China was located.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

NAIROBI, Nov. 15 (Xinhua) -- The UN refugee agency said on Tuesday there has been an outbreak of cholera in Dadaab, the world's largest refugee camp in Kenya, which is believed to have started among new arrivals who had most likely acquired it in Somalia or en route to the camp.The UN High Commissioner for Refugees (UNHCR) said the situation in Dadaab, home to Somalis fleeing famine and conflict, is being exacerbated by heavy rains and accompanying risks of waterborne diseases."Rains and flooding had affected the trucking of water to parts of the camps, and we fear some refugees resorted to using unsafe water from flooded areas," the UN refugee agency said in a statement released in Nairobi.According to UNHCR, there are now 60 cases in the camps, including 10 laboratory-confirmed cases and one refugee death. To manage the outbreak, UNHCR and partners have set up cholera treatment centres for severe cases, it said.The UN agency deplored insecurity which it said continues to affect aid efforts more than a month after the kidnapping of three aid workers in Kenya's Dadaab refugee complex.The UNHCR says insecurity is still hampering aid efforts in the area, despite the deployment of 100 Kenyan policemen in the last month.UNHCR is assisting them with vehicles, shelter and telecommunications equipment."Together with our partners, we are exploring options to gradually resume full operations despite continued security incidents in and around Dadaab. In the meantime, refugees are still receiving life-saving aid, namely food, water and health care," it said.According to the agency, most cases can be managed through oral rehydration solutions (ORS) that can be given at home or at the health posts."We are working with UNICEF and the Ministry of Health to train health workers in the community-based management of diarrhoea so that patients can begin treatment at home," it said.UNHCR said it has increased levels of chlorine, which kills cholera-causing bacteria, at water points in the camps. These, it said, are monitored to make sure they are maintained at the correct levels."We are also promoting hygiene practices among the refugees, especially the use of latrines and hand washing with soap. Each refugee received 250 grams of soap with the latest food distribution and this will continue monthly for several months," UNHCR said.Dadaab is home to more than 400,000 registered refugees, nearly all of them Somali, with an estimated 70,000 people having arrived in July and August as conditions in their homeland rapidly deteriorated.

BEIJING, Dec. 24 (Xinhua) -- Renowned China economist Li Yining said Saturday that adjusting the structure of China's economy is a "matter of life and death" while the structure of GDP is more important than its size.The focus of the country's economic structure adjustment now should be transforming the dual structure in the urban and rural economy, which causes the widening income gaps between urban and rural residents, Li said at the China Economic Forum.He also noted that the key to stimulating domestic demand is to raise the workers' wages.With the external demand waned, the Chinese government has attempted to turn to domestic consumers to take up the slack. The country vows to expand domestic demand next year and increase residents' income, especially for disadvantaged groups.However, Li said raising household income is not enough and the government also needs to improve its social security system as well as increase construction of affordable houses and public rental houses.The country plans to begin construction or renovation on at least 7 million housing units for low-income groups next year, Minister of Housing and Urban-Rural Development Jiang Weixin said Friday.

WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."
