BEIJING, Feb. 23 (Xinhua) -- A senior official of the ruling Forces pour la Defense de la Democratie (FDD) of Burundi said Tuesday the FDD hopes to strengthen cooperation with the Communist Party of China (CPC) and to further enhance the "brotherly friendship" with the CPC.Mohamed Rukara, vice president of the Council of Elders, the top decision-making body of the FDD, said in an interview with Xinhua that there are a lot of ruling experiences of CPC that the FDD can learn from.He said the CPC has gained great achievements in China's reform and opening up, realizing sustainable development, developing science and technology and striking corruption.He said Burundi has set "sustainable development" as the slogan for the 2010-2015 period, and he believed that his country can learn from China's successful experiences of reform and opening up and realize the goal of shaking off poverty by 2020-2025.Rukara, who is also a ombudsman, said corruption has been a big challenge facing his country, and he believed the FDD can learn from the CPC in this regard, as the latter has been combating corruption very hard and effectively.Appreciating China's aid and contribution to the development of Burundi, Rukara said the two parties and the two countries have had very good relations based on mutual respect.He welcomed more Chinese enterprises to invest in Burundi to support its development, and "the door will always be open to our brother."At the invitation of the CPC, Rukara is heading an FDD delegation for a visit to China starting from Saturday.

SAN FRANCISCO, April 18 (Xinhua) -- Apple Inc. has sued Samsung Electronics Co. over patent infringement in a latest suit, U.S. media reported Monday.The suit, filed last Friday in U.S. District Court in Northern California, alleged that Samsung's smartphones, such as "Glaxy S 4G" and "Nexus S," and the Galaxy line of tablet computers violated Apple's patent and trademark, according to All Things Digital, a technology and startup company news site."It's no coincidence that Samsung's latest products look a lot like the iPhone and iPad, from the shape of the hardware to the user interface and even the packaging," the report quoted an Apple representative as saying.Intellectual property suits can be often seen among mobile computing rivals, including suits between Microsoft and Motorola, a suit by Oracle against Google, and Apple's patent dispute with Nokia and HTC.Although Samsung supplies chips for a number of Apple products, Apple CEO Steve Jobs once openly mocked Samsung and other tablet makers as "copycats" during the iPad2 launch. Last month, Apple is reportedly partnering with China's Taiwan Semiconductor Manufacturing Co. to make iPad chips.

VIENNA, March 28 (Xinhua) -- Stress hormone is helpful in alleviating acrophobia, a morbid fear of great heights, according to a study by Austrian scientists.They published the findings in the recent Proceedings of the National Academy of Sciences of the United States of America.Frank H. Wilhelm, professor from the Department of Clinical Psychology, Psychotherapy and Health Psychology at the University of Salzburg, Austria, carried out the first study demonstrating the clinical effectiveness of hormones released at periods of high stress in anxiety.The study found hormones and other drugs could be a good addition to behavioral treatment of several anxiety disorders.People with acrophobia have formed a so-called fear memory, which could be activated when the fear-causing stimulus occurs. They tend to react with feelings of extreme fear and anxiety to the ride in a glass elevator.Hence, scientists conducted a confrontation therapy, trying to mask this memory.A total of 40 experimental subjects had been put in a safe environment to constantly confront the fear-inducing stimulus, until they had a new reaction to the perceived threat.Observations also suggested hormones released in high stress had impact on learning and memory.Additionally, stress hormones were believed to facilitate the storage of new, anxiety-free competence and experienced confidence in the therapy. Animal studies have shown that this emotional relearning benefits from cortisol, one of the stress hormones.

WASHINGTON, Jan. 20 (Xinhua) -- Visiting Chinese President Hu Jintao on Thursday called upon the U.S. Congress to continue helping the two countries boost their relations.Pursuing a healthy and steady development of China-U.S. ties is China's established policy and strategic choice, Hu stressed in talks here with Speaker John Boehner of the House and Majority leader Harry Reid of the Senate.It has also been the consensus of the U.S. administrations, whether Republican or Democratic, since the two countries established formal diplomatic relations 32 years ago, he added.Chinese President Hu Jintao (2nd L front) meets with U.S. Senate Majority Leader Harry Reid (2nd R front) on Capitol Hill in Washington, the United States, Jan. 20, 2011Thanks to the two nations' concerted efforts, the China-U.S. relationship has been moving forward steadily, Hu said, citing the two countries' increasing cooperation and coordination on trade, terrorism, climate change, Korean Peninsula denuclearization and other bilateral, regional and global issues.A sound relationship between Beijing and Washington not only serves the fundamental interests of both peoples, but greatly contributes to the peace, stability and prosperity of the Asia-Pacific region and beyond, the Chinese president said.With China and the United States differing in culture, social system and development level, it is normal for the two sides to have differences on some issues, he said.But what matters most is the common interests of the two countries, he stressed, saying that Beijing's position is that the two sides should seek common ground while reserving differences, so as to learn from each other and pursue common prosperity on the basis of mutual respect and equality.

WASHINGTON, May 27 (Xinhua) -- Two U.S. astronauts conducted the fourth and final scheduled spacewalks for space shuttle Endeavour 's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) announced.The seven-hour, 24-minute spacewalk completed by Mike Fincke and Greg Chamitoff at 7:39 a.m. EDT (1139 GMT) was the final spacewalk conducted by space shuttle astronauts before NASA turns over Endeavour and sister ships Discovery and Atlantis to museums. Space station crew will continue to make spacewalks for maintenance and repair tasks.At 5:02 a.m. (0902 GMT), Fincke and Chamitoff surpassed the 1, 000th hour astronauts and cosmonauts have spent spacewalking in support of space station assembly and maintenance. The milestone occurred four hours and 47 minutes into the spacewalk, the 159th in support of station assembly and maintenance, totaling 1,002 hours, 37 minutes.The astronauts completed their mission to stow the 50-foot-long boom on the station truss and work on some new installations to extend the space station's robotic arm. After that, shuttle commander Mark Kelly called Mission Control in Houston to mark the milestone -- after 12 years of efforts."Space station assembly is complete," Kelly said.It was the 248th spacewalk U.S. astronauts have conducted and the 118th from space station airlocks. Landing is scheduled for 2: 32 a.m. EDT (0632 GMT) on Wednesday at the Kennedy Space Center in Florida. Shuttle Atlantis is targeted to launch on July 8 for space shuttle's final flight.Endeavour lifted off on May 16 from the Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion- dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.
