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.

BEIJING, March 28 (Xinhuanet) -- Google Inc. is working with MasterCard Inc. and Citigroup Inc to develop a technology that could make mobile payments, according to media reports Monday.The new technology named "Nexus S Android" is embedded in Android mobile devices and allows customers to make purchases by waving their smartphones in front of a small reader at the checkout counter.Credit-card reader producer VeriFone Systems Inc, also involved in the new payment service, is developing contact-less devices that could allow people to pay with a wave or tap of credit card or a tap of smartphone.To use the service, holders of Citigroup-issued debit and credit cards must activate a mobile-payment application developed for one current model of Android phones. More models will be coming as the technology advances.Besides mobile payment, consumers would also be able to get targeted ads or discount offers, manage credit-card accounts and track spending through an application on their smartphones.Due to the deliberate design of the technology, customers have no need to worry about the security of their payment information. Nick Holland, a mobile-transactions analyst at Yankee Group, said the new technology is more sophisticated than credit cards with a magnetic stripe.With the coming service, Google is aiming to boost its advertising business by offering retailers more data about their customers and help them target ads and discount offers to mobile-device users near their stores.An insider told that Google was not expected to get a cut of the transaction fees.The service is expected to be released this year. Once released, it will broaden the uses of smartphones for everyday activities—from chatting to emailing to shopping.

SAN FRANCISCO, April 4 (Xinhua) -- Web exploit toolkits, or " packaged" attack frameworks that can be traded online, are rapidly growing as the top cybercrime weapon due to ease of use and high success rate, a new report has found."When it comes to conducting online crime, exploit toolkits are the weapon of choice for many cyber criminals," said the "2010 Top Cyber Security Risks Report" published by Hewlett-Packard Co. (HP) on Monday.The trend started in 2006 with the release of WebAttacker, considered by many to be the first modern day web exploit toolkit, according to the report.An emerging trend ensued and soon took off, and today the Internet is subjected to hundreds of exploits originating from these toolkits."With the ever-increasing, web-based criminal activity, the number of exploit toolkits has skyrocketed and shows no signs of slowing down," the report stated.Though protecting against attacks originated with web exploit toolkits is becoming increasingly difficult, there are ways to minimize the risk of infection, said the report, noting that one of the most effective defenses is to install patches onto host systems.The report also found that while the number of attacks against known vulnerabilities continues to rise, the number of discovered vulnerabilities has plateaued in 2010."We've discovered that rather than investing resources to uncover new exploits, attackers are focused on current, unpatched vulnerabilities in web applications, social networking sites and Web 2.0 interfaces," Mike Dausin, a manager at HP Digital Vaccine Labs, said in a statement.Data from the report showed that nearly half of all reported vulnerabilities exist in web applications, and third-party plug- ins to content management systems have become the leading cause of web application vulnerabilities.

SAN FRANCISCO, May 4 (Xinhua) -- Intel Corp. on Wednesday announced that it will mass-manufacture chips using new transistors featuring a three-dimensional (3-D) structure, calling it a technical breakthrough in microprocessors.The 3-D transistor, called Tri-Gate, represents a fundamental departure from the two-dimensional planar transistor structure that has powered computers, mobile phones and other modern electronics, Intel said."Intel's scientists and engineers have once again reinvented the transistor, this time utilizing the third dimension," Paul Otellini, Intel's chief executive officer, said in a statement.Intel on Wednesday also demonstrated a 22-nanometer (nm) microprocessor, codenamed "Ivy Bridge," which will be the first high-volume chips to use the new 3-D transistors.Ivy Bridge is scheduled for high-volume production readiness by the end of this year, the company said.According to Intel, the 3-D transistors enable chips to operate at lower voltage with lower leakage compared to previous transistors, providing up to 37 percent performance increase at low voltage versus the company's 32nm planar transistors.The gain means that the new 3-D transistors are ideal for use in small handheld devices, which operate using less energy to " switch" back and forth, Intel noted.

GENEVA, March 28 (Xinhua) -- The world is ill-prepared to respond to a severe influenza pandemic or to any similarly global, sustained, and threatening public health emergency, an independent expert-committee entrusted by World Health Organization (WHO) said at its fourth meeting here on Monday.The Review Committee, tasked to look into the experience gained in the global response to the influenza A (H1N1) pandemic in 2009, issued its preliminary report at the meeting.In the report, the Committee said, "global preparedness can be advanced through research, strengthened health-care delivery systems, economic development in low and middle-income countries and improved health status."It recommended that international society establish an extensive global public health reserve corps consisted of experts and public health professionals, which could be deployed to support countries in need, in case of future pandemics.Another suggestion was to create a contingency fund for public health emergencies to be held in trust at an institution such as the World Bank, in order to provide financial support during a declared public health emergency of international concern.The report also urged WHO member states to reach an agreement on sharing of viruses and access to vaccines, and encouraged them to run independent or cooperative influenza research program.WHO Director-General Margaret Chan said at the opening of the meeting that the report had offered "critical guidance to all ministers of health who need to make far-reaching decisions."She said the recommendations in the report would help to " improve the capacity of WHO and the international community to respond to public health emergencies" and therefore should be taken with "added urgency."In January 2010, WHO's Executive Board established a Review Committee, at Chan's proposal, to review the experience gained in response to the H1N1 pandemic, as well as the International Health Regulations and WHO's functioning in tackling the disease.The Committee is expected to prepare its final report out of the current preliminary version, and submit it to the decision- making body of WHO in May.
