WASHINGTON, Sept. 15 (Xinhua) -- The rates of new lung cancer cases in the United States dropped among men in 35 states and among women in six states between 1999 and 2008, according to a report released Thursday by the Centers for Disease Control and Prevention (CDC).Among women, lung cancer incidence decreased nationwide between 2006 and 2008, after increasing steadily for decades.The decrease in lung cancer cases corresponds closely with smoking patterns across the nation, the report said. In the West, where smoking prevalence is lower among men and women than in other regions, lung cancer incidence is decreasing faster. Studies show declines in lung cancer rates can be seen as soon as five years after smoking rates decline.The report also noted that states that make greater investments in effective tobacco control strategies see larger reductions in smoking; and the longer they invest, the greater the savings in smoking -- related health care costs. Such strategies include higher tobacco prices, hard-hitting media campaigns, 100 percent smoke-free policies, and easily accessible quitting treatments and services for those who want to quit."Although lung cancer among men and women has decreased over the past few years," said CDC Director Thomas Frieden in a statement. "too many people continue to get sick and die from lung cancers, most of which are caused by smoking. The more we invest in proven tobacco control efforts, the fewer people will die from lung cancer."Lung cancer is the most commonly diagnosed cancer, and the leading cause of cancer death in the United States. Cigarette smoking and exposure to secondhand smoke cause most lung cancer deaths in the United States.

BEIJING, Aug. 24 (Xinhuanet) -- Facebook said it is overhauling its privacy settings to give members easier, more precise control over who sees posts, photos and other content over the vast social network.Starting Thursday, Facebook is rolling out new privacy tools that are placed with each piece of content, replacing options that are now buried in overall account settings.Privacy has been a consistently sticky problem for the Palo Alto firm, which has felt the heat from privacy advocates and government regulators. And recently, Facebook faced stiffer competition from Google's new Google+ social network, which was hailed for including a "circles" feature with easy-to-use privacy settings.Instead of vague labels such as "everyone," which have been mistaken for a Facebook member's social network instead of anyone on the Internet, the new system will include more precise words such as "public.""You have told us that 'who can see this?' could be clearer across Facebook, so we have made changes to make this more visual and straightforward," Chris Cox, Facebook's vice president of product, said in blog post."The main change is moving most of your controls from a settings page to being inline, right next to the posts, photos and tags they affect. Plus there are several other updates here that will make it easier to understand who can see your stuff (or your friends') in any context," Cox said.While privacy advocates reserved judgment until the new settings are actually released, they were optimistic the changes will benefit consumers."These changes do make me feel very confident in the direction that Facebook is going and the way they are thinking about privacy," said Erica Newland, policy analyst for the Center for Democracy & Technology in Washington, D.C.

BEIJING, Sept. 11 (Xinhua) -- Despite a series of disasters, Chinese people tend to believe that the moon is still round and bright in the Mid-autumn Festival.Falling on Monday, the 15th day of the eighth month in the Chinese calendar, it is an important Chinese holiday, next only to the Spring Festival, and a chance for family reunion under the full moon, a symbol for happiness and prosperity.A staff worker shows newly-cooked moon cakes during a Mid-autumn festival celebration activity held in Tianjin, north China, Sept. 11, 2011. Some 100 children from Tianjin and southeast China's Taiwan attended the activity on Sunday.FAMILY REUNIONIn the railway station of Nanjing, capital city of east China's Jiangsu Province, passengers lined in long queues while waiting for their trains on Saturday.Although the three-day holiday seemed too short for a long trip, Xiao Liang carried several bags with him. "I bought wine for my dad, boiled salted duck for my mom, and health products for my grand parents," the young man beamed.In the southwestern Guangxi Zhuang Autonomous Region, Li Yukun didn't believe that she could reunite with her son for holiday. In fact, she never thought she could see the three-year-old boy again.Two years ago, Xiao Wei (pseudonym) from the Dalun village of the Beiliu city was kidnapped. His parents were desperate. "On special occasions like the Mid-autumn Festival, we shed tears while missing him," Li said.Police finally managed to get clues that a similar boy was adopted in the neighboring Guangdong Province.Li prepared for a feast with policemen to celebrate reunion with Xiao Wei.Since a campaign was launched to rescue trafficked children in Guangxi in 2009, 339 children were saved, half of whom had been sent back and could reunite with their parents in this festival.In Sichuan, 10 prisoners with good records in jail were given an opportunity to go back home for the holiday."In the past I could only receive greetings from my relatives behind the bars," a woman surnamed Chen said. "This year, my dream for home finally came true."Meanwhile, 171 prisoners had their jail terms shortened so that they could be released before the Mid-autumn Festival.

VIENNA, Sept. 22 (Xinhua) -- Climate change and rising temperature in the long term can lead to water shortages in the Alps region, international experts warned Thursday at the Water-Scarce Final Conference in the Austrian eastern city Graz.The Alpine region originally is rich in water resources due to a large number of glaciers, spring and abundant rainfall either in summer or winter. But global warming may change this situation which has been shown in the past years that the water reserve has reduced gradually due to climate change, warned the experts.Observation data have shown a significant decrease of 25 percent in groundwater recharge in the past 100 years which has also resulted in the reduction of mountain spring.Director of the Provincial Department of Water Resources of Styria Johann Wiedner point out, in 2003, droughts occurred in the eastern part of the Alps, including the state of Styria and water shortages were also found in other regions of the Alps. He said the phenomenon was giving a warning that people "have to do something."To this end, the European Union begun a project called "Alp Water Scarce" three years ago to observe water reserves, air temperature, water temperature and water table in this region and study the relationships among them.Wiedner also admitted that there is no shortage of water at least in the short term and water supply for the local residents is totally insured.

SAN FRANCISCO, June 14 (Xinhua) -- Google on Tuesday unveiled voice search for desktop computers and search-by-image, two new features allowing users to speak their search into the computer and search with the help of images.Speaking at the Internet search giant's Inside Search Event in San Francisco, Mike Cohen, head of Google's speech technology efforts, said its voice search is now available in 27 languages and dialects, an estimated coverage of around 5 billion people or two-thirds of world population.Voice search has already been available in Google's mobile search application from 2008. Adding the feature to desktops is part of Google's strategy to bring mobile innovations to its desktop search.The voice search on desktop performs similarly to voice search on smartphones -- users can click the microphone button and speak the query. It is only available via Google's Chrome browser for now.Cohen noted that the volume of Google mobile speech inputs has increased by six times in the last year.Also at the event, Google introduced search-by-image, which enables users to drag-and-drop, copy-and-paste image URL, or upload the image from the desktop into the search box. They can also use a Chrome or FireFox software extension to add images to the search.Google said the search-by-image feature will be available in most countries and regions over the next few days to Chrome users, noting that it will not collect and store any images that users use.
