SAN FRANCISCO, Dec. 8 (Xinhua) -- Twitter on Thursday started to roll out a major redesign of its interface in hopes of simplifying users' experience, as well as new brand pages to strengthen its relationship with advertisers.During a press conference at its new headquarters in San Francisco, Twitter Chief Executive Officer Dick Costolo and co- founder Jack Dorsey unveiled a whole new look of the social networking and microblogging service.According to an introduction video, the new homepage features profile on the left and the timeline on the right, which are flipped from the current positions and take less space than they used to.Three new buttons were also introduced as "Home," "Connect" and "Discover." "Connect" shows users who has mentioned them and suggests some accounts they might want to follow. "When you use Discover, you'll see results reflecting your interests -- based on your current location, what you follow and what's happening in the world," said Twitter.The overhauled interface is only available to a small group of users at first and will be rolled out to all users over the coming months. It will also remain consistent across Twitter's official mobile apps. Twitter has launched a page fly.twitter.com to explain all the changes.Along with the introduction of the redesign, Twitter also announced new brand pages on its platform. A total of 21 brand partners will be included in the initial launch, such as American Express, Best Buy, Bing, Coca-Cola, HP, Disney and Nike.Analysts said Twitter has ambitions to compete with similar brand pages from Facebook and Google+. According to eMarketer, Twitter's global advertising revenue is expected to reach 139.5 million U.S. dollars this year and approach 400 million dollars in 2013.

WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.

BEIJING, Jan. 19 (Xinhua) -- China's major textile companies are expected to witness an annual increase of 8 percent in their value-added output over the next four years, the Ministry of Industry and Information Technology said Thursday.The ministry published a plan regarding supporting the development of the textile industry during the country's 12th Five-Year Plan period (2011-2015), according to which the sector's exports will reach 300 billion U.S. dollars by 2015 with an annual growth of 7.5 percent.The industry is also expected to employ 20 million people by 2015 and its energy consumption per unit of value-added output will drop by 20 percent from 2010, the guideline said.The country will encourage the textile industry to enhance brand-building and aims to build 5-10 textile companies of global influence and 50 companies with an annual revenue of more than 10 billion yuan by 2015.The guideline warned of potential risks for the sector, including volatile changes in raw material prices, rising production costs and a complicated international trade environment.The guideline said the industry should develop new products and explore new markets to ensure a healthy development during the coming period.
