SAN FRANCISCO, June 20 (Xinhua) -- Facebook will launch new music service with a music tab and music dashboard in partnership with other online music services at its f8 annual developer conference in August, U.S. media reported on Monday.According to technology blog GigaOM, users will find a new tab called Music in the left-hand column on their pages, right where Facebook lists Photos, Friends, Deals and etc., and clicking on the new tab will open a page called Music Dashboard.The dashboard will feature friends' recommended songs, top songs, top albums and a "happening now" ticker that shows songs friends are playing.The blog said Facebook had reached partnership with Europe's popular music streaming service Spotify, which is gearing up to enter the U.S. market, and other online music services.Much of the attention at f8 should be focused on music, the blog quoted sources as saying.Last month, Facebook CEO and co-founder Mark Zuckerberg said at the eG8 Forum in Paris that he believes Facebook will focus on streaming music next.

SINGAPORE, Sept. 7 (Xinhua) -- Singapore scientists have found possible new ways to treat a type of aggressive breast cancer that is unresponsive to current forms of treatment, local broadcaster Channel NewsAsia reported on Wednesday.The team of scientists at the Genome Institute of Singapore ( GIS) and National University of Singapore (NUS), led by GIS senior group leader Qiang Yu, found that the enzyme EZH2 acts by inhibiting genes that stop the growth of tumors in the body.The insights could open the door to developing more effective treatment for fast spreading breast cancers, especially the estrogen receptor-negative breast cancer that is common all over the world.It was also found that through EZH2, cancer is promoted in the body by activating specific genes that impact breast cancer progression and cancer stem cell self-renewal.Yu said the new understanding on how EZH2 works as a cancer- causing gene in breast cancer has important therapeutic implication."The results suggest that small molecule drugs that block enzyme activity of EZH2 may not work for cancers caused by EZH2's activation genes," Yu said.Currently pharmaceutical companies have been developing drugs only to the block EZH2 enzyme activity so that tumor suppressers can perform their protective role in blocking cancer growth.Researchers said the next step would be to develop biomarkers to identify tumors with EZH2.This step would enable better treatment methods, with one of options being the development of therapies that shut down EZH2 completely and not just inhibit its enzymatic function.The findings have been published on the journal Molecular Cell.

HONG KONG, Sept. 9 (Xinhua) -- The Hong Kong Polytechnic University (PolyU) announced Friday that its surveying experts had successfully developed methodologies for precise mapping of the Moon, after intensive analysis of the data captured by the Chinese lunar orbiter ChangE-1 and other lunar exploration missions.According to the PolyU, the team has made significant contributions to lunar mapping. Their efforts culminated in the development of a unique and innovative approach to the creation of accurate 3D models of the lunar surface.The team has produced the most updated parameters of the lunar figure (the shape of the moon), which is essential for lunar mapping using 17.5 million laser altimetry measurements from the ChangE-1and the Japanese SELENE missions.In addition, they also used the new topographic and gravity models to calculate improved crustal thickness and mass distribution of the Moon and established that the average thickness of the Moon's crust is about 40 km on the near side and 50 km on the far side.It was introduced that the resulting lunar mapping was the hard work of a dedicated research team led by Professor Chen Yong-qi, Emeritus Professor of the Department of Land Surveying and Geo-Informatics, who is also serving on the Expert Committee of China's Lunar Exploration Programme (ECCLEP), with the concerted efforts of team members Prof. Chen Wu, Prof. Ding Xiao-li, Prof. Baki Iz, Dr. Bruce King, and Dr. Wu Bo.According to Chen Yong-qi, the lunar mapping project started in 2006. The primary objective was to develop the methodologies and techniques for mapping the Moon surface, which is much more challenging than mapping the Earth's surface because of very few surveyed control points which are essential for accurate map making.Statistics showed that there were only fourteen lunar laser ranging retro reflectors (LRRR) and Apollo lunar surface experiment package (ALSEP) transmitter sites with accurately known coordinates available only on the near side of the Moon, installed by the U.S. Apollo and former Soviet Union Luna missions in the 1960s.Moreover, according to the team, the gravitational field of the Moon is not as well-known as that of Earth, which means the accuracy of the computed lunar satellite's position at any given time is lower than for Earth satellites, thus degrading the mapping accuracy and reliability.In addition, the team expressed that highly reflective lunar surface created significant problems for the automatic processing of images to develop 3D models using the technique of photogramemtry, which is a widely used and highly reliable technique for the creation of maps and 3D models on Earth.Furthermore, the team also revealed they had a plan to compare such data with other data sources in order to evaluate the performance of the ChangE mapping sensors. Since Chen Yong-qi is serving on the ECCLEP, the team has direct access to more recent data captured by the ChangE satellite.

JIUQUAN, Gansu, Sept. 26 (Xinhua) -- Engineers are conducting the final preparations before launching China's first space laboratory module at the end of this week at a launch center in northwest China.The unmanned Tiangong-1 module was originally scheduled to be launched into low Earth orbit between Sept. 27 and 30. However, a weather forecast showing the arrival of a cold air mass at the Jiuquan Satellite Launch Center forced the launch to be rescheduled for Sept. 29 or 30, depending on weather and other factors."This is a significant test. We've never done such a thing before," said Lu Jinrong, the launch center's chief engineer.A full ground simulation was conducted on Sunday afternoon to ensure that the module and its Long March 2F carrier rocket are prepared for the actual launch.Cui Jijun, commander-in-chief of the launch site system and director of Jiuquan Satellite Launch Center, told Xinhua that they developed a new target spacecraft for the mission and made more than 170 technical improvements to the Long March 2F, China's manned orbital carrier rocket.Engineers have also made more than 100 updates at the launch site in order to make it compatible with the Tiangong-1, Cui added.The module will conduct docking experiments after entering orbit, which is the first step in China's space station program.Cui said the launch site has an updated computer center and command monitoring system and increased ability to adapt to changes in mission conditions, as well as the resources to handle both the launch and command duties. An integrated simulation training system for space launching has also been developed for the docking mission.The mission comes just one month after the Long March 2C rocket malfunctioned and failed to send an experimental satellite into orbit. The Tiangong-1 mission was subsequently rescheduled in order to allow engineers to sort out any problems that might occur during the launch.Cui said that engineers conducted a two-month comprehensive technical check on equipment at the launch site from March to May. The safety and reliability of all the instruments have been significantly improved."[The launch site] has the full conditions to conduct the Tiangong-1 mission," said Cui.The Tiangong-1 will remain in orbit for two years. During its mission, it will dock with China's Shenzhou-8, -9 and -10 spacecrafts.Unmanned docking procedures will be an essential step toward China achieving its goal of establishing a manned space station around 2020.

LOS ANGELES, June 20 (Xinhua) -- About 8 percent of children, or nearly 6 million in the U.S., have a food allergy, a much higher rate than previously estimated, a new study suggests.Not only is this estimate higher than some previous research has reported, allergic reactions are often severe and that many kids have more than one allergy, according to the study published online in Pediatrics on Monday.Of the children with confirmed (or probable) food allergies, about 39 percent had had severe reactions in the past, and 30 percent had more than one allergy, the study found.In the current study, researchers at the Northwestern University Feinberg School of Medicine surveyed parents of more than 38,000 children about whether their child had been diagnosed with a food allergy and had one or more of a number of symptoms, including anaphylaxis; swelling of the lips, eyes or face and skin rashes or hives.The study pinned down peanuts (25 percent of food-allergic children), milk (21 percent) and shellfish (17 percent) as the top three allergens.Severe reactions were most common among children with tree nut (more than 50 percent) and fin fish (more than 40 percent) allergies. The reactions were more likely among 14- to 17-year- olds compared with 0- to 2-year-olds, and more likely in children with multiple food allergies, the study found."These findings provide critical epidemiologic information to guide strategies for the prevention of food-induced reactions and for the diagnosis and management of childhood food allergies," the study noted.
