BEIJING, Sept. 14 (Xinhuanet) -- Facebook unveiled a new feature called "smart lists" on Tuesday, giving its users an easier way to share photos, posts and updates with smaller groups of friends.The new function, which commences on Wednesday, borrows from the success of the Circles feature of Google+, which allows users to categorize friends into groups.With the new feature, Facebook can automatically put your friends into groups, with the first four being work, school, family and city, based on the information of colleges, workplaces and geographic locations in users' profiles.The feature is optional to use, and the lists are customizable."This is really something we have been working on for four years," Facebook director of product management Blake Ross told AFP, adding "We think this is the way people will make lists going forward."In the meantime, the social networking site has also come up with "close friends" and "acquaintances" options.People can read the updates of their "close friends" more prominently in their news feed and just big news of their "acquaintances", according to Naomi Gleit, the director of product at Facebook who worked on the new feature.

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.

JAKARTA, Sept. 21 (Xinhua) -- Comprehensive efforts are needed to save coral reefs as their living compound is prone to environmental damage, an Indonesian expert told Xinhua in an exclusive interview on Tuesday.Nurul Dhewani Mirah Sjafrie, coordinator of Coral Reef Information and Training Center (CRITC) for western Indonesia at the Indonesian Science Institute, the government think-tank institution, said that currently only more than five percent of coral reefs in Indonesia are in "excellent condition.""Based on monitoring of the thousands of observation stations we have, the rest are in damage, bad and moderate condition," Sjafrie said in her office.She said that it is not impossible to increase the number as long as all people are aware of the importance to save coral reefs."People should be aware that coral reefs live in sea with warm enough temperature of 18-25 Celsius degree with certain level of brightness, among others. If the requirements are fulfilled, we can see coral reef growing safely," said Sjafrie.She also said it needs upstream-to-downstream arrangement to support the efforts."For example, in western Indonesia, we have many big rivers. If illegal logging practice keeps continuing, it will cause sedimentation in the sea. It means there is a decreasing quality. So, coral reef salvation is not only conducted in ocean," Sjafrie said.She also expressed concern that many people dump garbage in rivers."They throw their garbage in plastic bags. For plastic only, it takes 100 years to be completely decomposed. Let's say 10-15 percent of our people do the malpractice everyday, you can imagine how many garbage entering the sea," she said.Sjafrie said that the key to guard coral reef sustainability is in human habit."Coral reef destruction could be caused by nature such as tsunami, earthquake, crown torn (Acanthaster plancii) that consumes coral reefs. But the biggest factor is human with their destructive fishing using bombs," she said.According to Sjafrie, people do the practice with three causes, namely ignorance, needs and greed.She added that efforts have been conducted by the government, private sector and non governmental organizations (NGOs) to save coral reefs."We have a program called the CORMAP of Coral Reef Rehabilitation and Management Program. The government uses instrument of National Program of People Empowerment while NGOs do their part. If we could combine the actions, we could reach the same goal," she said.She added that the government train people to be productive by providing skills and in the same time, her organization and NGOs socialize and campaign the importance of coral reefs."When people have better jobs and activities and they are equipped with the awareness, they will do positive thing and stop destroying the sea," Sjafrie said.

BEIJING, Aug 4 (Xinhuanet) – A new urine test might help doctors detect prostate cancer and better evaluate a patient's treatment options, according to American reseachers Thursday."This is a tool that men and their physician can use to help them decide whether it's appropriate to get a biopsy now or delay that decision," said lead researcher Dr. Scott Tomlins, a pathology resident at the University of Michigan Health System.The test looks for two genetic markers associated with prostate cancer. The first, called TMPRSS2:ERG, is caused by two genes changing places and fusing together; it is thought to cause prostate cancer. Since the gene fusion is only seen in about half of cancer patients, the test also looks for another marker, called PCA3."We are exploiting some new bio-markers to try to refine the PSA (prostate-specific antigen) test," Tomlins said.

(Comac) on Sunday set up its European office in Paris, the second overseas branch after its U.S. office, marking a new step for China's aviation industry in opening-up and international exchanges."The establishment of Comac Europe office is very significant. It represents the strategic cooperation between China and France and will deepen the two sides' collaboration in aerospace and all areas concerned," Chinese Ambassador Kong Quan said at an opening ceremony, citing Europe's influence in global aerospace industry and civil aviation market."Taking self-dependent innovation as the strategic cornerstone, Comac meanwhile actively conducts international cooperation and draws upon advanced technologies and experience in global civil aviation industry...," Comac President Jin Zhuanglong said.French Secretary of State for Transport Thierry Mariani (4th L), Chinese Ambassador to France Kong Quan (3rd L) and General Manager of the Commercial Aircraft Corporation of China (COMAC) Jin Zhuanglong (2nd R) attend the unveiling ceremony of COMAC Europe Office in Paris, France, June 19, 2011. The COMAC Europe Office was offically opened here Sunday.The Chinese aerospace manufacturer has built up cooperative relationship and partnership with dozens of enterprises and institutions in many countries and regions since its establishment in May 2008 in Shanghai.Regional jet ARJ21 and the trunkliner C919 are two flagship products of the young Chinese company. The group is now working to achieve certification and delivery of ARJ21-700 aircraft by the end of this year, Jin said.With regard to China's C919 trunkliner program, Jin said COMAC has signed cooperation agreements with 17 international companies in the United States and Europe, and has actively explored collaboration with GECAS, British Airways and Ryanair."In the context that the world economy is on recovery from the financial crisis, the civil aviation industry is facing great challenge. We are willing to keep close contact with all relevant public administrations and forge friendly relations and cooperation with overseas suppliers to contribute to the development of world civil aviation industry," Jin said.For the French State Secretary for Transport Thierry Marianne, who also attended the opening ceremony, the Chinese aviation market has great potential in the years to come, and China is estimated to need 3,000 new planes."We have understood that China had decided to build its own aerospace industry.
