BEIJING, May 20 (Xinhuanet) -- Scientists have discovered a Jupiter-sized exoplanet that is completely unbound from a host star, according the scientific journal "Nature" published Thursday.The research was conducted by astrophysicists from Osaka University in Japan.Using the technique called "gravitational microlensing", scientists turned their telescopes towards the centre of the Milky Way and detected this "lonely planet" moving in a extremely large orbit, which suggested it does not connect to any solar system.Then they estimated the total number of such wondering planets could be as many as 400 billion, based on the detection efficiency. This number far outnumbers the main-sequence stars such as our Sun."This is an amazing result, and if it is right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut.And scientist began to consider the possibility that liquid water could exist on this kind of unbound planets. "That might be an attractive possibility for life," said David Stevenson, a planetary scientist at the California Institute of Technology.

SAN FRANCISCO, May 10 (Xinhua) -- Google on Tuesday launched its long-awaited cloud-based music service Music Beta without any label licenses it originally wanted.The search giant introduced the digital music locker service at its annual I/O developer conference in San Francisco. So far, only U.S. users can access the service by requesting an invitation from Google while priorities will be given to those with the Verizon version of the Motorola Xoom tablet and attendees of the I/O conference.Since Google failed to come to a license agreement with major music labels, Music Beta is essentially a massive cloud hard drive. Users cannot share their Music Beta by Google tunes or purchase new songs. It allows users to upload 20,000 songs into the cloud, compared with Amazon Cloud Drive's 2,000 songs and 5 GB limit for free accounts.Any web-connected devices with a browser or supporting Flash can stream music from the digital locker, but the service is only for Android-powered devices.Music Beta also gets Instant Mix, a similar intelligent feature to Apple's Genius playlist creator, which creates new playlists based on a single song by analyzing its characteristics.Before unveiling the service, Google told U.S. media Monday night that the current Music Beta is not the service Google had wanted to offer and it will continue to seek licenses with major music labels.

BEIJING, March 15 (Xinhuanet) -- Chris Poole, the 22-year-old founder of 4Chan.org, criticized Facebook's approach and spoke up for online anonymity at South by Southwest Interactive in Austin, Texas, according to media reports Tuesday.Poole called out early in his keynote speech at the huge Austin tech event, referencing this Zuckerberg quote from David Kirkpatrick’s book "The Facebook Effect": "Having two identities for yourself is an example of a lack of integrity.""Anonymity is authenticity; it allows you to share in a completely unfiltered way," Poole countered. "It allows you to play in ways, you might not if people knew who you are.”Losing the ability to be anonymous on the Internet is, "a kind of loss of the innocence of youth," Poole said, crediting 4chan’s culture-infiltrating creativity to anonymity. "You can’t make mistakes,“ and then leave them behind, like the olds did pre-Facebook. If your mistakes ever made it to the Internet, they’re with you wherever you go.Poole — known by the 4chan handle "moot" — was to promote his new meme-generating venture, Canvas, still in beta testing.Launched for anime enthusiasts in 2003, 4chan is one of the most popular image-sharing bulletin boards on the Internet, with most of that traffic hitting 4chan’s notorious "random" image board, the /b/ board.

BEIJING, March 27 (Xinhua) -- China's search giant Baidu has pledged to remove all unauthorized literary works from its free online literary database Wenku within three days.After receiving requests from copyright owners to remove their works, Baidu has sped up its process of checking for unauthorized items. The unauthorized works were uploaded by Internet users to Wenku without prior approval from the authors, a spokesman for the Chinese search engine giant said in a statement.In the statement issued Saturday, Baidu apologized for what has "hurt the feelings of a certain number of writers" during Wenku's previous stage of operation, according to a report published Sunday by daily newspaper The Beijing News.Baidu said it respects copyright laws and will continue to cooperate with publishers and writers to establish a revenue-sharing model that will ensure that copyright owners receive a share of revenues from online versions of their works.Hailing Baidu's move to remove the unauthorized works, Wang Yefei, deputy head of Beijing Municipal Bureau of Copyrights hopes that Baidu and the publishers should work together to find win-win methods of mutual cooperation, according to the newspaper.However, some writers involved in the copyright row are dissatisfied with remedies Baidu has so far taken.Shen Haobo, CEO of Beijing Motie Book Co. Ltd, one of the six negotiators representing writers in Thursday's negotiations, told the Beijing Youth Daily that Baidu apologized only because of public pressure, but it did not mean to alter its current operation model for Wenku."Without changes in the operation model, the unauthorized works, even if removed now, could be uploaded again sometime later. Besides, it's unacceptable that Baidu reiterated that it had not infringed on our copyright," Shen was quoted as saying.Popular writer and blogger Han Han posted an open letter he wrote to Baidu's CEO Li Yanhong in his blog, indicating that he might take further actions to uphold his rights if Baidu's stance remains unchanged.Baidu's online literary database Wenku is an open platform for online resource sharing. It has been in operation since 2009.More than 40 Chinese writers posted an open letter online on March 15, accusing Baidu of stealing their works and infringing on their copyrights. Baidu's Wenku database was blamed for allowing literary works to become available online without the authors' prior approval.Baidu was asked to make a public apology, compensate for the writers' losses and halt any cases of copyright infringement.
