BEIJING, Sept. 20 (Xinhuanet)-- Google's executive chairman Eric Schmidt is to face a Senate hearing on whether the company is abusing its dominance in Internet search, according to media reports on Tuesday.At the Wednesday's hearing before the Senate Judiciary Committee's antitrust panel, Schmidt will argue that critics are wrong to say Google gives preference to its own products, instead, Google is just trying to deliver the best-cultivated search results for users. The issue of search ranking is a touchy subject with Google, which says its algorithm is devised to give users the most useful result so they will come back.Another focal point of the hearing, which Schmidt concerned most is "scrapers", those who game its search algorithm, for example, taking commonly searched words, combine them into a nonsensical block of text and throw it up on the Web to grab eyeballs and advertising dollars.Google believes that, if scrapers succeed too often, consumers will lose confidence in search and turn to other resources, thus posing an existential threat to the company.Regulators in the U.S. and abroad have been looking into various aspects of Google's business practices since the company's 2007 purchase of ad firm DoubleClick. At the moment, European regulators are conducting an antitrust inquiry into Google's search business while the Federal Trade Commission is doing likewise. Google relies overwhelmingly on its core product, Internet search, and dominates the market for that product. It handles around two-thirds of U.S. Internet searches and more than 80 percent in many European countries, according to comScore Inc.

LOS ANGELES, July 5 (Xinhua) -- NASA's Juno spacecraft is 30 days away before its first launch window opens, the Jet Propulsion Laboratory (JPL) announced on Tuesday."One month from today, our first launch window opens at 11:34 a. m. EDT (8:34 a.m. PDT) and lasts 69 minutes," said Jan Chodas, Juno project manager from NASA's JPL in Pasadena, Los Angeles."Our primary launch period is 22 days long, and so if weather or other issues come up on Aug. 5, we have 21 more days to get Juno flying. Once we get Juno into space, it's a five-year cruise to Jupiter.""The launch window is the length of time allotted every day for an attempt to launch the spacecraft," said Chodas. "The launch period is the period of time in days when everything is in the right place to get your mission off to the right start."For a mission like Juno, getting everything in the right place includes considering the size of the rocket and spacecraft, where our home planet -- and in particular Juno's launch pad -- is pointed at any moment, and its location in space relative to other celestial objects like Juno's final target, Jupiter.Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from pad 41-C at the Cape Canaveral Air Force Station, Florida.The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska. Lockheed Martin Space Systems, Denver, built the spacecraft.

WASHINGTON, Aug. 4 (Xinhua) -- Observations from NASA's Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars, the U.S. National Aeronautics and Space Administration (NASA) announced Thursday.Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere."The best explanation for these observations so far is the flow of briny water," said Alfred McEwen of the University of Arizona, Tucson.McEwen is the principal investigator for the orbiter's High Resolution Imaging Science Experiment and lead author of a report about the recurring flows to be published in Friday's edition of the journal Science.Seven such sites on the planet have been confirmed, with 20 more possible, McEwen said."What makes these new observations so interesting is they occur at much lower latitudes where temperatures are much warmer and where it's actually possible for liquid water to exist," said Arizona State University geophysicist Phil Christensen, one of the scientists who studied the images beamed back from the orbiter.The study does not prove water exists, but identifies it as the best explanation. It's worthwhile to think about alternative reasons for these observations, but none seems to fit as well as briny water, McEwen said."I think it's going to be laboratory experiments on Earth that give us the best confirmation or refutation," he said.

He also said that China's track record of sharing knowledge with the World Bank was creating a "catalyst for consensus" and that placed the institutions in good stead to benefit from China's economic consistence."The Chinese policy mix includes a tool box of administrative measures ... In general, one of the lessons that the United States and others can learn (from China) is that to have supervisory policies for bank regulatory systems can be a useful part of the tool set."Aside from hinting that over-heating global real estate markets could benefit from China's regulatory tightening, Zoellick suggested if China moved to more market-exposed decision making, he hoped China's bank regulators would not step too far back."Over time China will be better served to move to more precise and market signals than more administration-based decisions. Over time China will want to move to more market based decisions ... but I don't want this to be interpreted that supervisors don't have to supervise," he said.

BERLIN, June 8 (Xinhua) -- The deadly strain for the E. coli outbreak was found again on cucumbers, authorities of German state Saxony-Anhalt said on Wednesday. The strain O104 was found on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg, said State Health Minister Holger Paech.The dustbin belongs to a family in which three members have been ill. Paech said. The father only suffered a slight stomach upset, while the mother was once treated at a hospital and is now released. Their daughter is suffering from hemolytic-uremic syndrome (HUS), a serious complication from the infection of E. coli.However, experts were not clear about how the bacteria came to the cumbers, which have been in the dustbin for a week and a half."It is not clear and we are not able to determine how it reached there." Paech said.German authority first detected such bacteria from Spanish cucumbers on May 26, which has been overthrown by the laboratory tests in Hamburg last Tuesday.On Sunday, German State Lower Saxony issued a warning on bean sprouts as a possible source for the outbreak, which was proven to be negative on Monday.The German government has faced increasing criticism from abroad and at home for dealing with this crisis, as it has wrongly blamed the source of the infection for twice and there is a lack of coordination between different research institutes on the outbreak.John Dalli, European Union Health Commissioner, was quoted by local daily Die Welt saying "we have to rely on the experience and expertise across Europe, and even outside Europe."The Max Planck Institute for Infection Biology in Berlin also called for a federal government representative to coordinate the various government agencies which are dealing with the crisis.A federal government representative could increase cooperation between ministries and reduce mixed messages from the government, said director Stefan Kaufmann.On the same day, Germany's national disease control center, the Robert Koch Institute, said the number of infection has shown an overall decreasing trend but it is still uncertain whether the decline is due to people staying away from vegetables or to the waning of the source of infection.Until Wednesday, 25 deaths have been reported while the infection cases have increased more than 2,600 in 12 countries around the world.
