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.

SAN FRANCISCO, Nov. 11 (Xinhua) -- Facebook is close to a settlement with the U.S. Federal Trade Commission (FTC) over the charges that the world's largest social network misled users about its use of their personal information, the U.S. media reported Friday.The proposed settlement would require Facebook to get users' consent before making "material retroactive changes" to its privacy policies, said a report from The Wall Street Journal, citing people familiar with the talks.The agreement with the FTC is also expected to ripple much farther in the tech industry as more companies are developing programs to observe people's online behavior and profiting from the personal information, such as the target advertisements.With a current 800-million-user base worldwide, Facebook changed its user policy in late 2009 to disclose more of users' personal information without adequate notice, leading to a federal investigation along with mounting complaints online.On Thursday, two U.S. representatives asked the Palo Alto, California-based company to explain a February patent application, saying that it raises alarm bells about how the company tracks users on other websites.Outside the U.S., Facebook is also drawing criticism on its privacy policies in countries with strict privacy laws, such as Germany. On Thursday, German authorities said they are considering suing Facebook over its use of facial recognition technology.In a PBS interview aired earlier this week, Facebook's founder and chief executive officer Mark Zuckerberg and chief operating officer Sheryl Sandberg said the company is focused on privacy, addressing that it gives users the ability to protect their privacy.Zuckerberg said Facebook users volunteer all of their personal information on the social network, unlike other Internet giants and advertising networks that compile information "behind your back."

BEIJING, Sept. 30 (Xinhuanet) -- Tobacco companies concealed the knowledge of radioactive substance in cigarettes from public for over four decades, a new study revealed.The revelation was made by a research team from the University of California, Los Angeles, published on Thursday in the online edition of the U.S. medical journal Nicotine and Tobacco Research.The researchers analyzed 27 timeworn documents and discovered that tobacco companies had knew the existence of polonium-210, a hazardous radioactive substance, in the tobacco since 1959.The companies studied polonium-210 throughout the 1960s, and concealed their findings about the carcinogenic potential of the radioactive substance.Hrayr Karagueuzian, the study's lead author, said the tobacco companies' deception surprised him.According to the revelation, the companies had knew the "cancerous growths" in the lungs of smokers, and even calculated how much radiation a regular smoker would inhale over 20 years.Karagueuzian and his team conducted again the study recorded in the tobacco documents and found that the radiation in cigarettes would cause up to 138 deaths for every 1,000 smokers over a period of 25 years.However, tobacco manufacturer denied that they had concealed the facts from the public.David Sutton, spokesman of Philip Morris, the largest U.S. tobacco company, said the polonium-210 was a "naturally occurring element in the air" and had been widely discussed by the public health community for years.
