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.

MOSCOW, May 13 (Xinhua) -- The main and backup crews that will fly to the International Space Station in June have passed preflight tests and are ready for space travel, the Russian Cosmonauts Training Center said Friday.The main crew includes Russian cosmonaut Sergei Volkov, Japanese astronaut Satoshi Furukawa and American astronaut Michael Fossuma.A Russian spaceship Soyuz TMA-02M will send the crew to the space station on June 8, Interfax news agency reported.The backup crew includes members from Russia, the Netherlands and the United States.The crews were tested on the various emergency situations they could face during the flight.Next Monday, the commission will make a final choice of crewmembers for the launch.The crew will spend 161 days in orbit and conduct three space walks.

CANBERRA, April 14 (Xinhua) -- The Australian federal government could struggle to get its carbon tax through parliament, as key independent Member of Parliament (MP) Tony Windsor on Thursday warned the plan may never become a reality.Windsor, who is one of the independents Prime Minister Julia Gillard will rely on to get her carbon tax pass the Parliament, said while climate action will benefit the bush, he will not "vote for something that does nothing"."There is no carbon tax, there may not be a carbon tax," he told ABC News on Thursday morning."The prime minister doesn't have the numbers, as I understand it at the moment."I have a vote, others do as well, so you can never guarantee something before it gets through a minority parliament."Windsor said people in his rural New South Wales electorate were concerned about the lack of detail around the proposed carbon tax.Gillard played down his comments, saying that Windsor, who sits on the multi-party climate change committee, had been "perfectly consistent" in his approach to the carbon price debate."He does believe climate change is real ... that pricing carbon is the best way, an important way, of tackling climate change," Gillard told ABC Radio on Thursday."(But) he's going to look at the (legislative) package and wait to the end and then judge (it)."Gillard added that the Labor government remains determined to introduce a carbon tax from mid-2012 followed by an emissions trading scheme.

BEIJING, Feb. 12 (Xinhua) -- Sales revenue of Beijing's auto market in 2011 might shrink by 60 billion yuan (about 9.1 billion U.S. dollars) due to the city limiting the number of cars purchased each month, a commerce official said Saturday.Car sales revenue will drop to 100 billion yuan in 2011 from last year's 160 billion yuan, Wang Shuxia, chief for marketing section with the Beijing Municipal Commission of Commerce, told a working meeting of the commission.A control on car purchases introduced this year limits new car license plates to 240,000 in 2011, said Wang.In 2010, more than 800,000 new cars drove onto Beijing's roads, worsening the chronic gridlock in this Chinese national capital of nearly 5 million automobiles.Wang estimated that Beijing's car sales this year will hit 580,000 units, as some cars will be sold to buyers outside of Beijing while others will be purchased by buyers who are replacing older cars.Car owners who replace their old vehicles can obtain car license plates directly without taking part in the lottery that allots 20,000 new plates each month.

CAIRO, Jan. 23 (Xinhua) -- The first training session for Egyptian Chinese language teachers to improve their teaching ability started on Sunday in Cairo.The session, under the supervision of the Chinese Confucius institute, will concentrate on the exchange of experiences in teaching the Chinese language in Egypt and the enhancement of Egyptian teachers' ability to make better use of the textbooks.The three-day training session will contain language and cultural courses by professors and instructors from famous Chinese universities such as Beijing University and Beijing Foreign Studies University, said Li Shengjun, head of the Confucius Institute at Cairo University.Nearly 60 Egyptian Chinese language teachers, including 14 professors, from universities including Cairo University, Ain Shams University and Minya University will attend the training courses.China has established 691 Confucius institutes and classes in around 69 countries until 2010, including nine in the Arab countries.
