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.

BEIJING, Jan. 30 (Xinhua) -- China hoped Egypt could restore social stability and normal order at an early date, Foreign Ministry spokesman Hong Lei said Sunday."China has been closely watching the development of the situation in Egypt," Hong said when asked to comment on the ongoing turmoil in the country."Egypt is a friendly country with China, and we hope Egypt could restore social stability and normal order at an early date," he said.

BEIJING, Jan. 24 (Xinhua) -- China's top economic planner said Monday that price supervision and control measures have achieved steady progress with 2010's Consumer Price Index, slightly exceeding the target ceiling by 0.3 percentage points to hit 3.3 percent.To rein in soaring commodities prices, joint efforts have been made to manage inflation expectations, promote production, ensure supplies and strengthen price supervision in 2010, said the National Development and Reform Commission (NDRC) in an online statement.Prices of necessities accelerating during the second half of 2010 have been contained with vegetable prices down 9.4 percent in December from the previous month last year, it said.Further, prices of edible vegetable, pork, egg, sugar,liquefied petroleum gas and clothing also decreased significantly in December month on month, the statement said.To cope with rising prices beginning in July 2010, especially prices of basic supplies, the central government promptly introduced joint inter-ministerial meetings to discuss price controls among 17 ministries and ordered local governments to establish the same mechanism, it noted.Local governments have worked on improving agricultural facilities, especially in south China's Hainan province, to increase vegetables supplies for northern cities over the past year, the statement said.The statement forecasts that vegetable planting areas in 2010's autumn and winter will increase 530,000 hectares year on year, sending output to 337 million tonnes.To ensure production and supply, departments have worked to reduce fertilizer exports and promote links between production areas and purchasing areas, it added.Further, relevant authorities also took measures to stabilize prices of electricity and coal, and to ensure smooth transportation of agricultural produce.Authorities also granted temporary subsidies and raised basic wages and minimum living subsidies for urban and rural residents to guarantee people's daily life.

BEIJING, May 19 (Xinhuanet) -- Google on Wednesday began fixing a security hole in some 97 percent of Android phones that could let hackers snatch important credentials at public WiFi hotspots.The fix, which addresses a hole allowing hackers to access the contacts, calendars and photos on an Android phone connected to an open WiFi network, will take a few days to cover every phone, a Google spokesman said.Unlike a traditional software update, the problem exists on Google's servers, so Android users won't need to manually take action.The newest versions of Android, including the new wave of tablets running its Honeycomb software, are not affected by the bug, according to the researchers at Germany's University of Ulm who initially reported the issue.The vulnerability could also cause devices synchronizing with Google Picasa web albums to transmit sensitive data through unencrypted channels, the researchers added.The Google spokesman said the company's security team is still investigating those claims.

WASHINGTON, March 25 (Xinhua) -- NASA's Stardust spacecraft depleted fuel and ceased operation on Thursday after a 12-year run, the U.S. space agency said Friday."This is the end of the spacecraft's operations, but really just the beginnings of what this spacecraft's accomplishments will give to planetary science," said Lindley Johnson, Stardust-NExT and Discovery program executive at NASA headquarters in Washington."The treasure-trove of science data and engineering information collected and returned by Stardust is invaluable for planning future deep space planetary missions."Artist's concept of Stardust spacecraft nearing EarthLaunched on Feb. 7, 1999, Stardust flew past the asteroid named Annefrank and traveled halfway to Jupiter to collect the particle samples from the comet Wild 2. The spacecraft returned to Earth's vicinity to drop off a sample return capsule eagerly awaited by comet scientists.NASA re-tasked the spacecraft as Stardust-NExT to perform a bonus mission and fly past comet Tempel 1, which was struck by the Deep Impact mission in 2005. The mission collected images and other scientific data to compare with images of that comet collected by the Deep Impact.The Stardust-NExT met all mission goals, and the spacecraft was extremely successful during both missions. From launch until final rocket engine burn, it travelled approximately 3.54 billion miles.After the mileage logged in space, the Stardust team knew the end was near for the spacecraft. With its fuel tank empty and final radio transmission concluded, the most traveled comet hunter will move from NASA's active mission roster to retired."This kind of feels like the end of one of those old western movies where you watch the hero ride his horse toward the distant setting sun -- and then the credits begin to roll," said Stardust-NExT project manager Tim Larson from NASA's Jet Propulsion Laboratory in Pasadena, California. "Only there's no setting sun in space."
