SAN FRANCISCO, March 23 (Xinhua) -- Yahoo Inc. on Wednesday introduced a new feature to its search engine, which the company said can deliver answers and direct access to websites before users complete their query or hit the search button.The new feature, called Search Direct, predicts search results as fast as a person types and presents those results dynamically, Yahoo said."With today's launch, direct answers -- not the search results page -- is the primary focus. We are redefining the search process and prominently displaying direct answers where search decisions are being made," Shashi Seth, Yahoo's senior vice president of search and marketplaces, said in a statement."Search Direct is evidence of Yahoo continuing to lead innovation in search, enabling people to take action faster, find what is most important, and sample what is possible with the next stage of search technology," he added.Yahoo announced that Search Direct is rolling out in a public test version to its users across the United States Wednesday, and will be available in other Yahoo products and markets later this year.

SHANGHAI, May, 13 (Xinhua) -- Scientists attending a recent high-level conference on robotics agreed that great progress has been made in the field, but strict rules for the safe usage of robots should be implemented."Four years ago, if you went into a Chinese factory and said 'robots can help you work,' you would be kicked out. But now, China has a large industrial robot market, along with Japan, the Republic of Korea and the United States," says Li Zexiang, general chair of the 2011 International Conference on Robotics and Automation (ICRA 2011), which concluded Friday in Shanghai.Chinese robotics researchers have suggested to the government that rules and regulations for robot usage should be created. Professor Wang Tianmiao from the Beihang University (BUAA) told Xinhua about the suggestions during the conference.Wang says that in the future, it might not be possible for artificial intelligence to take the place of humans in some social roles. However, Wang says that mankind should pay close attention to the possible dangers of advancements in robotics, as the industry is currently undergoing dramatic changes.The five-day conference, which is organized by the Institute of Electrical and Electronics Engineers (IEEE), took place in China for the first time ever since its first session in 1984, which took place in the city of Atlanta in the United States.Media reports show that Japan, the Republic of Korea (ROK) and several Western countries have already drafted rules about the safe use of robots.

HONG KONG, March 18 (Xinhua) -- After over a year's efforts, scientists from Shanghai and Hong Kong announced on Friday that they have completed the whole genomic sequencing work of Isaria cicada, a rare herb highly valued in traditional Chinese medicine, which will help facilitate its further development in medical and nutrition fields.It is the first time that the whole genomic sequence of Isaria cicada has been released, said the scientists from Shanghai Institute of Bio-Asia Life Science and the Hong Kong University of Science and Technology (HKUST), who participated in the research.The result was announced at the International Biomedical Scientists and Biotechnology Forum 2011 held in the day at the Hong Kong Science Park.According to the result, the genomic size of Isaria cicada, a medicine traditionally used to treat children's diseases, is about one eightieth of human genome, containing about 16,000 genes.The tests that had been done proved that Isaria cicada, with many high-quality genes not recognized or used by human beings yet, has been deeply involved in important life processes like metabolism, providing new ways for further development of Isaria cicad in bio-medical area, said a scientist from HKUST.The genome map will also help accelerate the artificial cultivation of Isaria cicada, enhancing its medicine and nutrition value and making it available in a larger market, according to the scientist.

  

BEIJING, Feb. 8 (Xinhuanet) -- China's railroads and highways will see their busiest day of the Spring Festival holiday on Tuesday when the number of travelers returning to major cities hits its peak, just as a cold snap sweeps across much of the country, the ministries of railways and transport said on Monday.The Ministry of Railways said on its website that there had been a sharp rise in the number of travelers leaving smaller cities on Monday bound for such places as Beijing, Shanghai and Guangzhou.The ministry said the number of people on the move on Tuesday is likely to make the day the Spring Festival travel peak.The nation's roads are also likely to be at their Spring Festival maximum on Tuesday and Wednesday, the Ministry of Transport reported on Monday on its official website.The National Meteorological Center (NMC) added on Monday that a moderate cold snap was expected on Tuesday, causing temperatures to fall by between four and six degrees in most parts of China.The weather pattern will bring widespread rain and snow to the southern part of China from Wednesday to Friday, the NMC said.The Ministry of Railways said on its website that it has asked its local branches to be prepared for the upcoming icy weather.Meanwhile, the local authorities in big cities have been bracing for the arrival of massive numbers of travelers as the Spring Festival holiday winds down.In Shanghai, tens of thousands of public transportation workers cut their holidays short and put 27 additional bus lines on the road to meet demand as passengers began arriving in large numbers at the city's railway stations.The influx began on Saturday night, according to local newspaper Wenhui Daily.On Sunday, the pressure intensified on the Qinghai-Tibet railway, two days earlier than expected.As a result, the railway company organized additional workers to facilitate the flow of people through Xining Railway Station in Northwest China's Qinghai province.Many volunteers have also been pitching in to help keep people moving and have offered to do various jobs at stations, such as helping people buy tickets and assisting them in checking their travel schedules.Among them, Liu Chen, a student from the Guangzhou-based Zhongkai University of Agriculture and Engineering, has been helping people at Guangzhou Railway Station by carrying their bags."One day, I helped more than 70 passengers with their luggage and, after all of them got on the trains, it felt like my legs were almost paralyzed," he said.The Hohhot railway bureau in North China's Inner Mongolia autonomous region said it is expecting so many extra passengers that it has scheduled four additional trains for lines to Chongqing and Beijing.With so many people scrambling to get back from family gatherings and holidays to their jobs in China's big cities, the rush to buy tickets has been phenomenal. Tickets for trains that will leave Nanjing on Tuesday for Beijing, Guangzhou, Harbin and Changchun had virtually all gone on Monday morning, Jiangsu's Yangtse Evening Post reported.On Sunday, the fourth day of Spring Festival, the country's railways carried a total of 5.3 million travelers, which was up by 12.8 percent on the 4.7 million who rode the rails a day earlier, according to the Ministry of Railways.Another 38.6 million travelers made Spring Festival trips on Sunday on buses and ships, according to the Ministry of Transport.The traditional chunyun period, or Spring Festival travel season, runs for 40 days and is calculated in two phases: 15 days before Spring Festival Eve and 25 days after it, as stipulated by the central government.China's railways moved about 77.3 million passengers during the first 15-day period, which ran from Jan 19 to Feb 2, the Ministry of Railways reported.
