SAN FRANCISCO, June 6 (Xinhua) -- Apple's chief executive officer Steve Jobs on Monday took a break from his medical leave to introduce the company's new cloud-based service iCloud.Jobs, in his trademark black turtleneck and jeans, got a standing ovation in San Francisco's Moscone Center when he appeared on stage. Someone screamed "I love you," and Jobs said " it always helps and I appreciated it.""ICloud stores your content in the cloud and wirelessly pushes it to all your devices," said Jobs, calling it Apple's "next big insight."According to Apple, iCloud Backup will automatically back up users' iOS devices to iCloud daily over Wi-Fi when they charge their iPhone, iPad or iPod touch. Backup content includes purchased music, apps, camera roll, device settings and app data. It will also automatically upload documents from iWork in the cloud and pushes them to users' all relevant devices.The service will currently be free and replaces the former MobileMe which Apple once charged 99 U.S. dollars per year.Users will get five gigabytes of memory which is not counting purchased apps, music or books. A beta version is available on Monday and the final version will be shipping with iOS 5 this fall, with paid plans for more storage to be announced at that time.For a 24.99-dollar paid music plan named iTunes Match, a user's iTunes library will be scanned and they will gain instant access to those tracks or albums from compatible devices, rather than uploading them. Song files, including those converted from CDs, will also be uploaded to iCloud if they are not matched in iTunes stores but recognized by music labels.Jobs pointed out that iTunes Match paid plan is cheaper than Amazon's offering and Google has not announced a price yet, saying "it's an industry leading effort."The Apple CEO finally showed a photo of the company's new, massive data center in North Carolina to emphasize Apple is ready for iCloud service.Before Jobs, Apple executives introduced Lion, the eighth major release of Mac OS X and iOS 5, the next version of Apple's mobile operating system.Phil Schiller, Apple's marketing chief and Craig Federighi, the OS X software vice president, introduced ten key new features among the 250 ones of the new Mac operating system, including multi-touch features that bring the users experience on iPhone to their computers.Lion will be available to customers in July in Mac App Store. The price is adjusted to 29.99 dollars from 129 dollars Apple used to charge for upgrades.Scott Forstall, head of Apple's iOS software, demoed Apple's new mobile operating system, noting that iOS already has 44 percent of the mobile operating system market.The new version iOS 5 will have more than 200 new features, including a Notification Center that catches missed calls, mail messages and phone messages; and a feature called Reminder that provides virtual Post-it notes using geolocation technology.The new mobile operating system also integrates Twitter with many other iPhone apps and has a Newsstand on which the newspaper and magazines icons will be the actual covers of the publications.Apple said that iOS 5 is coming to the public this fall, which probably means the new iPhone is coming in the fall as well.Apple's new services are unveiled at its annual Worldwide Developers Conference (WWDC). Jobs kicked off the keynote event by saying that Apple had sold out 5,200 tickets to attendees just in two hours.

WASHINGTON, Sept. 12 (Xinhua) -- An enzyme that appears to play a role in controlling the brain's response to nicotine and alcohol in mice might be a promising target for a drug that simultaneously would treat nicotine addiction and alcohol abuse in people, U.S. researchers find.Over the course of four weeks, mice genetically engineered to lack the gene for protein kinase C (PKC) epsilon consumed less of a nicotine-containing water solution than normal mice, and were less likely to return to a chamber in which they had been given nicotine. In contrast, normal mice steadily increased their consumption of nicotine solution while the mice lacking PKC epsilon did not.The study conducted by researchers at the Ernest Gallo Clinic and Research Center, affiliated with the University of California, San Francisco, appeared Monday in the online edition of the Proceedings of the National Academy of Sciences.In normal mice, as in humans, nicotine binds to a certain class of nicotinic receptors located on dopamine neurons, which causes dopamine to be released in the brain. Dopamine creates a feeling of enjoyment, and thus prompts a sense of reward. Researchers found that mice lacking PKC epsilon are deficient in these nicotinic receptors.The finding complements earlier research in which researchers found that mice genetically engineered to lack the PKC epsilon enzyme drank less alcohol than normal mice and were disinclined to return to a chamber in which they had been given alcohol."This could mean that these mice might not get the same sense of reward from nicotine or alcohol," said Gallo senior associate director and investigator Robert Messing. "The enzyme looks like it regulates the part of the reward system that involves these nicotinic receptors."The reward system is a complex of areas in the brain that affect craving for nicotine, alcohol and other addictive substances.The next step in the research, said Messing, would be to develop compounds that inhibit PKC epsilon. The ultimate goal, he added, would be medications that could be used "to take the edge off of addiction by helping people get over some of their reward craving."

SAN FRANCISCO, Aug. 17 (Xinhua) -- Microsoft's cloud-based software Microsoft Office 365 on Wednesday experienced its first major outage since its introduction in late June."At approximately 11:30 a.m. PDT, Microsoft became aware of a networking issue affecting customers of some Microsoft services hosted out of one of our North American data centers," said Steven Gerri, general manager for Microsoft Global Foundation Services, in a statement"We apologize for the inconvenience that Office 365 outage has caused today. We are working on resolving the issue," the software giant said via Twitter.Outages were reported in Chicago, Denver and New York City among other locations. According to tweets from affected users, they were unable to access their email and managers were unable to manage accounts.The outage lasted approximately five hours and services have been restored for the moment.According to Microsoft service-level agreement, Microsoft guarantees a 99.9 percent level of uptime. If it fails to reach 99.9 percent uptime, users are eligible for 25 percent service credit.As more industry giants try to entice users to move to the "cloud," a term refers to the management and provision of applications and data over the Internet, the downtime again reminds cloud computing users that they must prepare to deal with outages and rethink their dependency on the service, analysts said.Amazon has suffered two major cloud outages earlier this month and back in April, impacting some of its high-profile users like movie streaming service Netflix and location-based social networking Foursquare.Analysts recommend cloud users to store data with multiple service providers to minimize the risk and limit their dependency on cloud services for business-critical processes.Available in 40 countries and regions since June 28, Office 365, which Microsoft CEO Steve Ballmer said is "where Microsoft office meets the cloud," combines Microsoft Office, SharePoint Online, Exchange Online and Lync Online into a single cloud-based package for business users.

SEOUL, Sept. 26 (Xinhua) -- Samsung Electronics, the world's second-largest manufacturer of mobile phones, launched its first smartphones based on fourth-generation (4G) communication technology in a bid to meet growing demand for high-speed wireless services. Galaxy S2 LTE and Galaxy S2 HD LTE compatible with long- term evolution (LTE) technology were rolled out at a media event held in central Seoul on Monday. The two new smartphones support LTE with data transmission five times faster than the existing third-generation (3G) mobile phones, featuring functions offered by Galaxy S2 smartphones, the company said.The Galaxy S2 LTE is equipped with an Android 2.3, or the latest version of the Android platform, a 4.5-inch wide Super AMOLED display and a 1.5 gigahertz dual core processor, while the Galaxy S2 HD LTE is featuring a 4.65-inch high-definition (HD) AMOLED display with 110 percent natural color reproduction and 180- degree viewing angle. "The 4G LTE technology became the base for enjoying high-speed and high-resolution wireless services. The new products will meet rising demand for such services in an environment where global wireless operators are transitioning to 4G networks," Shin Jong-kyun, president and head of Samsung's mobile communications business, told reporters.Shin forecast sales of the new LTE smartphones would approach the ones of the existing Galaxy S series, adding that it may take time to reach the goal as the LTE networks have yet to be covered nationwide.Global sales of the Galaxy S2 smartphones reached more than 10 million units since its debut in April, according Samsung. The nation's top wireless carrier SK Telecom plans to offer LTE service nationwide by 2013, with the country's No. 3 mobile operator LG Uplus aiming to cover the service across the country next year.
