SAN FRANCISCO, June 14 (Xinhua) -- Google on Tuesday introduced several new features of its search services on desktops and smartphones, which the Internet search giant said could help users get to their search results faster.SEARCH BY VOICE, IMAGESpeaking at Google's Inside Search event in San Francisco, Mike Cohen, head of the company'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.

GUANGZHOU, Aug. 2 (Xinhua) -- China conducted a scientific survey of the southwest basin of the South China Sea around the end of July, the China Geological Survey (CGS) said on Tuesday.The expedition acquired a "high-quality integrative geographic profile" of the basin's 1,000-km-long survey line, which stretches from the region's Xisha Islands to the Nansha Islands, according to a press release from the CGS.The expedition allows scientists to study the evolution of tectonic activity in the South China Sea and predict disasters such as earthquakes and tsunamis, the CGS said.The survey is also of significance for countries around the South China Sea, as they will be able to use the data to enhance their ability to prevent and reduce the effects of disasters, it said.The survey lasted from June 13 to July 31 and was carried out by the Chinese research vessel Tanbao in collaboration with a French research unit. Recent typhoons prevented the researchers from surveying part of the region, therefore some data is yet to be supplied later, the CGS said.

LOS ANGELES, July 7 (Xinhua) -- Obesity rates in the United States climbed over the past year in 16 states, and not a single state reported a decline in the proportion of excessively overweight residents, according to a report released on Thursday.The report, published by HealthDay News, found that more than 30 percent of the people in 12 states are obese. Four years ago, only one state could make that claim.Twenty years ago, "there wasn't a single state that had an obesity rate above 15 percent, and now every state is above that," said Jeff Levi, executive director of Trust for America's Health, which compiled the report."We have seen a dramatic shift over a generation," he added. " This isn't just about how much people weigh, but it has to do with serious health problems like diabetes and hypertension. These are the things that are driving health care costs."With the exception of Michigan, the 10 most obese states are in the South. The Northeast and West reported the lowest obesity rates. In addition, in eight states, more than 10 percent of adults suffer from type 2 diabetes, according to the report.Mississippi, where 34.4 percent of the people are obese, has the highest obesity rate. Other states with obesity rates above 30 percent include: Alabama, Arkansas, Kentucky, Louisiana, Michigan, Missouri, Oklahoma, South Carolina, Tennessee, Texas and West Virginia. Thirty-eight other states have obesity rates above 25 percent.For the second year in a row, obesity rates rose in Illinois, Kentucky, Massachusetts, Missouri, Rhode Island and Texas.And, for the third year straight, more residents of Florida, Kansas, Maine, Oklahoma and Vermont tipped the scale toward obesity.Colorado, with an obesity rate of 19.8 percent, is the only state where the rate is less than 20 percent, the report found.The study also found that more than one-third of children and adolescents are obese or overweight, with the highest prevalence in the South. However, the new data indicate that obesity among children and adolescents may have leveled off, except among the heaviest boys.

BEIJING, Sept. 27 (Xinhuanet) -- Last-minute preparations for the launch of the Tiangong-1 spacecraft began at the Jiuquan Satellite Launch Center on Monday, meaning the vehicle can soon embark on a mission that will eventually have it dock with a spaceship, according to the center.That feat, if carried out successfully, will mark the completion of China's first rendezvous and docking mission.At the launch site on Monday afternoon, crews were putting in place pipes and cables that will be used to inject fuel into the rocket that will carry Tiangong-1 into outer space.Without complications from the weather or other causes, the Long March II-F rocket will lift off from the launch center on Thursday or Friday, taking the Tiangong-1 with it, according to the Xinhua News Agency.Despite the preparations, space experts said carrying out the plan still comes with many risks. They explained that the spacecraft and much of the other equipment being used is new and has not been tried on an actual mission."Tiangong-1 is a brand new spacecraft designed by China and is bigger and heavier than the Shenzhou spaceships China had developed as a means of transporting astronauts from the Earth to space," said Yang Hong, chief designer of Tiangong-1.In a vertical position, the Tiangong-1 looks like a cigar standing 10.4 meter tall, a height equal to that of a three-story building. It weighs 8.5 tons and has a maximum diameter of 3.35 meters, a dimension shared by its launch vehicle, he said.In comparison, the Shenzhou spaceship stands shorter, at nearly 9 meters, is slimmer, having a diameter of less than 3 meters, and weighs less.In another difference, the Tiangong-1 is composed of two modules rather than the three that had made up the Shenzhou spaceship. Of the Tiangong-1's two primary components, one is an experimental module that contains a place that astronauts can live and work in on future missions. It is also equipped with a docking port.The other chief component, a resource module, will provide the craft with power.Astronauts on Tiangong-1 will have 15 cubic meters of space to move in, "much more than they had in the Shenzhou spaceship", Yang said.Inside the spacecraft are two sleeping sections with adjustable lighting systems, exercise equipment, entertainment systems and visual communication devices, he said.Hou Xiangyang, who helped design Tiangong-1, said: "The sleeping section is big enough for a 1.8-meter-tall man to sleep in. An astronaut can adjust the light as he likes."In space, Tiangong-1 will fly in a horizontal position. A paint scheme inside will help the astronauts aboard maintain their sense of direction; the module's inner walls will be in two colors, one commonly associated with the sky and one with the ground."This will help astronauts avoid feeling as if they are standing upside down in the microgravity environment," he said.Yang said the Tiangong-1 spacecraft is expected to stay in orbit for two years and rendezvous and dock with three different spaceships. Beyond the Shenzhou VIII, ships named Shenzhou IX and Shenzhou X will embark on similar missions; at least one of the two is to be manned.Before astronauts climb on board Tiangong-1, the conditions inside its experimental module will be adjusted to ensure they can live in an environment that contains enough oxygen, moisture and heat to be safe.Tiangong-1 was originally scheduled to be launched into a low orbit around the Earth between Sept 27 and 30. The earlier days were removed as possible launch dates, though, after forecasters predicted a cold air mass would move into the area containing the Jiuquan Satellite Launch Center.To ensure the spacecraft and Long March II-F carrier rocket are ready for launch, a full ground simulation was conducted on Sunday afternoon.
