NEW YORK, March 9 (Xinhua) -- The U.S. stocks dropped on Wednesday, the two-year anniversary of the beginning of a bull market, as concerns of oil prices and Middle East unrest continued to weigh on investors' minds.U.S. crude oil price dipped on Wednesday as crude inventories rose more than expected, though Brent crude rose on fears caused by continued violence in Libya.Meanwhile, Rex Tillerson, the CEO of energy giant Exxon Mobil Corp., said on Wednesday that he didn't think the recent jump in oil prices was hurting the U.S. economy just yet, but it's getting close.The market was worrying that the surging oil prices would hurt global economic recovery. Adding to those concerns, the Portuguese government's two-year cost of borrowing hit the highest level since it joined the eurozone in a bond auction on Wednesday.Wednesday marked the two-year anniversary of the beginning of a bull market. On March 9, 2009, the Dow Jones Industrial Average closed at 6,547 and the Standard & Poor's 500 Index closed at 677. The Dow is back above 12,000 now and the S&P 500 index has almost doubled.Meanwhile, the wholesale report was slightly positive, but still failed to boost the market. According to the U.S. Commerce Department, the wholesale inventories climbed 1.1 percent in January. Sales at the wholesale level rose 3.4 percent, the largest gain since November 2009.Economists expected that as businesses kept expanding, demands for products would continue to grow. And larger sales may also encourage businesses to keep restocking their shelves and boost factory production.According to the report, a 10.6-percent rise in demand for petroleum helped lift sales, reflecting higher oil and gas prices.While some investors were concerned that surging oil prices might have a negative impact on economy, some others believed the boost in sales and inventories in January hinted that the economy could withstand the impact.The Dow Jones industrial average lost 1.29 points, or 0.01 percent, to 12,213.09. The Standard & Poor's 500 Index was down 1. 80 points, or 0.14 percent, to 1,320.02. The Nasdaq declined 14.05 points, or 0.51 percent, to 2,751.72.

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.

WASHINGTON, March 9 (Xinhua) -- U.S. space shuttle Discovery landed safely at the Kennedy Space Center in Florida on Wednesday, ending its nearly 27-year flying career as the world's most- traveled spaceship.According to NASA, Discovery touched down at 11:57 a.m. EST ( 1657 GMT) after a 13-day resupply mission to the International Space Station (ISS)."For the final time: wheels stop," Discovery's commander Steven Lindsey called out as the shuttle rolled to a full stop.Discovery lifted off on Feb. 24 from the Kennedy Center and arrived at the space station on Feb. 26.During the mission, the astronauts installed a spare closet module on the space station, completed some important repairs and delivered the first humanoid robot, though it will need more time to be assembled and made operational.The 330-pound R2 consists of a head and a torso with two arms and two hands. Once it is unpacked -- likely several months after its arrival at the station -- it will initially be operated inside the Destiny laboratory for operational testing, but over time both its territory and its applications could expand.Aboard the station, its primary job for now is teaching engineers how dexterous robots behave in space. However, the hope is that through upgrades and advancements, it could one day venture outside the station to help spacewalkers make repairs or additions to the station or perform scientific work.

ULAN BATOR, Jan. 25 (Xinhua) -- China hopes to promote political mutual trust and deepen pragmatic cooperation with Mongolia, a senior Chinese official said here Tuesday.Yan Junqi, vice chairwoman of the Standing Committee of the National People's Congress (NPC), China's top legislative body, made the remarks when meeting with Mongolian Parliament Speaker Damdin Demberel and Prime Minister Batbold Sukhbaatar on the sidelines of the 19th Annual Meeting of Asia-Pacific Parliamentary Forum.She said China and Mongolia are friendly neighbors and important cooperation partners, adding that China is willing to work together with Mongolia to achieve mutually beneficial cooperation and common development so as to bring more benefits to both sides and the two peoples.Demberel and Batbold said that consolidating and promoting the good-neighborliness and friendly cooperation with China is one of the priorities of Mongolia's foreign policy.They added Mongolia is willing to enhance high-level exchanges with China and deepen their pragmatic cooperation in various fields to bring bilateral ties between the two countries to a higher level.The 19th Annual Meeting of the Asia-Pacific Parliamentary Forum opened on Monday in Ulan Bator, Mongolia's capital.The forum was established in Tokyo in 1993.
