KUWAIT CITY, Nov. 27 (Xinhua) -- Two warships from China on Sunday docked at Kuwait's Shuwaikh port to start a five-day official visit to the Gulf Arab emirate.The tour by the destroyer "Wuhan" and the frigate "Yulin" marked the first visit by Chinese naval vessels to Kuwait since the two countries established diplomatic ties 40 years ago."This visit marks a historic occasion and Kuwaiti navy looks forward to future cooperation to improve the relationship and friendship between our two navies," said Colonel Khaled Ahmad Abdallah from Kuwait's navy.The flotilla was part of the ninth Chinese naval convoy to conclude its escort mission in the Gulf of Aden and waters off Somalia.Commander of the flotilla Guan Jianguo hopes the visit would enhance mutual cooperation between the two navies, which in turn would contribute to boosting bilateral relations.The flotilla would visit Oman after its stay in Kuwait.

WASHINGTON, Dec. 22 (Xinhua) -- The journal Science on Thursday chose the HPTN 052 clinical trial, an international HIV prevention trial as the 2011 Breakthrough of the Year.The study found that if HIV-infected heterosexual individuals begin taking anti-retroviral medicines when their immune systems are relatively healthy as opposed to delaying therapy until the disease has advanced, they are 96 percent less likely to transmit the virus to their uninfected partners. Findings from the trial, first announced in May, were published in the New England Journal of Medicine in August.The study was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health."The HPTN 052 study convincingly demonstrated that anti- retroviral medications can not only treat but also prevent the transmission of HIV infection among heterosexual individuals," said NIAID Director Anthony Fauci in a statement. "We are pleased that Science recognized the extraordinary public health significance of these study results."Science's list of nine other ground-breaking scientific achievements from 2011 include:The Hayabusa Mission: After some near-disastrous technical difficulties and a stunningly successful recovery, Japan's Hayabusa spacecraft returned to Earth with dust from the surface of a large, S-type asteroid. This asteroid dust represented the first direct sampling of a planetary body in 35 years, and analysis of the grains confirmed that the most common meteorites found on Earth, known as ordinary chondrules, are born from these much larger, S-type asteroids.Unraveling Human Origins: Studying the genetic code of both ancient and modern human beings, researchers discovered that many humans still carry DNA variants inherited from archaic humans, such as the mysterious Denisovans in Asia and still-unidentified ancestors in Africa. One study this year revealed how archaic humans likely shaped our modern immune systems, and an analysis of Australopithecus sediba fossils in South Africa showed that the ancient hominin possessed both primitive and Homo-like traits.Capturing a Photosynthetic Protein: In vivid detail, researchers in Japan have mapped the structure of the Photosystem II, or PSII, protein that plants use to split water into hydrogen and oxygen atoms. The crystal-clear image shows off the protein's catalytic core and reveals the specific orientation of atoms within. Now, scientists have access to this catalytic structure that is essential for life on Earth -- one that may also hold the key to a powerful source of clean energy.Pristine Gas in Space: Astronomers using the Keck telescope in Hawaii to probe the faraway universe wound up discovering two clouds of hydrogen gas that seem to have maintained their original chemistry for two billion years after the big bang. Other researchers identified a star that is almost completely devoid of metals, just as the universe's earliest stars must have been, but that formed much later. The discoveries show that pockets of matter persisted unscathed amid eons of cosmic violence.

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.
