BEIJING, May 24 (Xinhuanet) -- Scientists revealed for the first time the molecular structure of proteins, which enables bacteria to transfer electrical charges, according to a new study. The revelation was published in Proceedings of the National Academy of Sciences in the U.S. on Monday.Scientists used a technique called "x-ray crystallography" to reveal the molecular structure of proteins, which work as atom-sized "wires" discharging excess electricity."This is an exciting advance in our understanding of how some bacterial species move electrons from the inside to the outside of a cell," said lead author Tom Clarke of the University of East Anglia's School of Biological Sciences in Norwich, England.He said this discovery means "We can now start developing efficient 'bio-batteries' as the viable energy source in the future."Still, it could take perhaps a decade to go. Before that, existing uses of such bacteria needed to become 100 or 1,000 times more efficient, he said.The advance could also hasten the development of microbe technology that can help clean up oil or uranium pollution, he said.Microbes might in future be enlisted to clean up nuclear accidents such as Japan's Fukushima Daiichi disaster, he added.

HEFEI, Feb. 2 (Xinhua) -- Chinese Premier Wen Jiabao has visited farmers and workers in Dabieshan Mountain area, an old revolutionary base in east China's Anhui Province, to extend new year greetings ahead of the Spring Festival, which falls on Thursday.On Tuesday, Wen went to the area's Jinzhai County, once an important Red Army revolutionary base, to learn about the local economic and social development situation.He visited Zhaoyuan Village and called in on farmer Zhao Mengqi. Wen chatted with Zhao, asking about his family's income and their preparations for the lunar new year.Zhao works as a migrant worker in Wujiang City, an economically-developed part of Jiangsu Province. His son and daughter-in-law work in Shanghai. They returned home on the eve of the Spring Festival."With the income we earn working in cities and what we earn growing crops, our family income has increased and we have rebuilt and renovated our house," Zhao told Premier Wen. A paved road now allows buses to reach the village, Zhao added.Wen said, "Only when the people living in old revolutionary bases live better lives can we feel relieved."At farmer Zhao Kongying's home, Wen joined the family in making "yuanzi," a glutinous rice ball traditionally eaten during the Spring Festival.Wen later went to Hetang Village. There he visited villager Yu Shuhua's home and urged the local government to provide more help to needy people to ensure they have a happy lunar new year.At dinner time, he went to villager Zhang Jiasheng's home, joining the family to prepare dinner. He wore an apron and made a soup for the family.During the dinner, Zhang told Wen the village is rich with chestnuts, tea and traditional Chinese medicine, adding that tourism is also a source of income for the village.Wen said help and support for the old revolutionary base should be boosted, so that local people can lead happier lives.Wen also extended new year greetings to workers at the Meishan hydropower station in Jinzhai County.At retired worker Wan Benrong's home, Wen asked about the family's living conditions and their preparations for the lunar new year.After being told the couple received an extra 140 yuan each of monthly pension this year, Wen said the government has increased the basic pension for retired workers seven times since 2005."Our objective is to make you feel secure," Wen said.

SEOUL, April 12 (Xinhua) -- South Korea has downgraded its alert level for foot-and-mouth disease (FMD) one notch as the disease has practically come to an end, the Ministry for Food, Agriculture, Forestry and Fisheries said Tuesday.The ministry said that it lowered the alert level from "orange" to "yellow," the second-lowest status in the four-tiered alert system, as no additional burial of livestock has occurred in three weeks after the last case in Hongseong, South Chungcheong Province, on March 21.The country dropped the alert level from the highest level of " red" to "orange" on March 24.The highly contagious animal disease, first confirmed on Nov. 29, has forced the country to cull more than 3.47 million livestock, mostly pigs and cattle, resulting in losses of 3 trillion won (2.6 billion U.S. dollars).The ministry, meanwhile, said that 670 animal quarantine experts will continue to decontaminate livestock farms once every week and keep close watch to see if any animals become sick.

BEIJING, Feb. 5 (Xinhua) -- Lending to China's small and medium-sized enterprises (SMEs) rose faster than loans to large enterprises last year, according to the People's Bank of China (PBOC), the central bank.Outstanding loans to small enterprises by banks and financial institutions jumped 29.3 percent year on year to 7.55 trillion yuan (1.15 trillion U.S. dollars) in 2010, while loans to medium-sized enterprises stood at 10.13 trillion yuan, up 17.8 percent, said the PBOC.Outstanding loans to large enterprises rose 13.3 percent to 13.42 trillion yuan, highlighting the government's efforts to optimize the loan structure, the PBOC said.About 99 percent of Chinese enterprises are SMEs which contribute 60 percent of the country's gross domestic product.Financing has long been difficult for Chinese SMEs as banks prefer to lend to big companies, particularly reputable state-owned enterprises.The government has moved to help SMEs get finance by differentiating the reserve requirement ratio for the Rural Credit Cooperative, the major lender to SMEs, and encouraging innovation in SME bond issuance.In July last year, the PBOC asked financial institutions to establish independent criteria for approving loans to SMEs and to improve efficiency in processing SME loan applications.The PBOC said SME loan growth would continue to accelerate this year.

LOS ANGELES, May 5 (Xinhua) -- NASA has selected three planetary missions from which it will pick one potential mission to look at Mars' interior for the first time, NASA's Jet Propulsion Laboratory (JPL) announced on Thursday.The Mars mission, to be launched in 2016, would be led by JPL, according to the announcement.The other two missions would study an extraterrestrial sea on one of Saturn's moons; or study in unprecedented detail the surface of a comet's nucleus, said JPL in Pasadena, Los Angeles.The selected investigations could reveal much about the formation of our solar system and its dynamic processes, JPL said.Each mission will receive three million dollars to conduct its mission's concept phase or preliminary design studies and analyses, JPL said in a news release.After another detailed review in 2012 of the concept studies, NASA will select one to continue development efforts leading up to launch. The selected mission will be cost-capped at 425 million dollars, not including launch vehicle funding, according to JPL.NASA's Discovery Program requested proposals for spaceflight investigations in June 2010. A panel of NASA and other scientists and engineers reviewed 28 submissions."NASA continues to do extraordinary science that is re-writing textbooks," said NASA Administrator Charles Bolden. "Missions like these hold great promise to vastly increase our knowledge, extend our reach into the solar system and inspire future generations of explorers."
