BEIJING, Dec. 29 (Xinhua) -- China on Thursday issued a white paper on the development of space industry since 2006 and the major tasks for the next five years.The white paper titled "China's Space Activities in 2011" was the third white paper on the country's space activities issued by the State Council Information Office, following the one in 2000 and another in 2006.The Chinese government has made the space industry an important part of the nation's overall development strategy and adhered to exploration and utilization of outer space for peaceful purposes, the white paper said.Over the past few years, China has ranked among the world's leading countries in certain major areas of space technology, it said, adding that in the next five years, there will be new opportunities to the country's space industry.At the same time, China will work together with the international community to maintain a peaceful and clean outer space and endeavor to promote world peace and development, the document said.FUTURE MISSIONSMajor tasks listed in the white paper for the next five years include space transportation system, Earth satellites, human spaceflights and deep-space exploration.The country will launch the Shenzhou-9 and Shenzhou-10 spaceships and achieve unmanned or manned rendezvous and docking with the in-orbit Tiangong-1 vehicle, the paper said.China also plans to launch space laboratories, manned spaceship and space freighters, and will start a research on the preliminary plan for a human landing on the moon, the document said.As an important part of deep-space exploration, the country's lunar probe projects follow the idea of "three steps" -- orbiting, landing and returning.In next five years, the country plans to launch orbiters for lunar soft landing, roving and surveying to implement the second stage of lunar exploration, then it will start the third-stage project of sampling the moon's surface matters and get those samples back to Earth, the white paper said.In addition, China will build a space infrastructure frame composed of Earth observation satellites, communications and broadcasting satellites, plus navigation and positioning satellites.MAJOR PROGRESSAccording to the white paper, breakthroughs have been made in major space projects, including human spaceflight and lunar exploration, since 2006.From Sept. 25 to 28, 2008, China successfully launched the Shenzhou-7 manned spaceship and became the third country in the world to master the key technology of astronaut space extravehicular activity.In November 2011, China accomplished the first unmanned space rendezvous and docking test between the Tiangong-1 space lab module and Shenzhou-8 spaceship.In addition, the country's lunar probe projects have achieved milestone breakthroughs over the past five years. China successfully launched two lunar probes, the Chang'e-1 on Oct. 24, 2007, and Chang'e-2 on Oct. 1, 2010.The first probe retrieved a great deal of scientific data and a complete map of the moon while the second created a full higher-resolution map of the moon and a high-definition image of Sinus Iridium.

SAN FRANCISCO, Nov. 1 (Xinhua) -- Yahoo, which has been rumored to sell all or part of its business, announced on Tuesday that it is buying data-driven advertising network Interclick for around 270 million U.S. dollars.Interclick is a technology company providing data targeted solutions and optimization technologies."This investment underscores our focus on enhancing the performance of both our guaranteed and non-guaranteed display business across Yahoo and our partner sites and, combined with Yahoo's reach and advertising leadership, will deliver a powerful solution for marketers," said Ross Levinsohn, Yahoo's executive vice president for the Americas region.Some analysts said Interclick's technology could help Yahoo to grow its display advertising market share as Google and Facebook have gained on or surpassed the company in the area.But the acquisition also raised questions considering Yahoo's financial situation after it reported last month its revenue in the last quarter decreased by 5 percent year-over-year. The company is also in a chief executive officer (CEO) search following the firing of former CEO Carol Bartz in September and amidst reports of a possible takeover.Although in a financial struggle, Yahoo still has around 700 million unique monthly visitors and its news division is the biggest online news site with around 81.2 million unique visitors in August.Tech giants like Google and Microsoft are reported to be considering providing finance for the acquisition of Yahoo by another company or a group of companies.In a report on Monday, Bloomberg News reported that Yahoo is leaning toward selling Asian assets and redistributing the proceeds to shareholders, rather than selling itself to a group of buyers. Yahoo's shares fell more than 5 percent after the possibility was reported.

YAGNON, Oct. 23 (Xinhua) -- Myanmar has launched anti-dengue high fever campaign in seven townships in Yangon simultaneously as a prevention measure against the disease, according to the Health Department Sunday.The campaign was carried out in the weekend in collaboration with health department staff and members of social organizations.Dengue preventive and control measures were occasionally launched in schools and wards in Myanmar with the aid of World Health Organization, U.N. Children Fund, three Disease Fund, Global Fund and Japan International Cooperation Agency.According to statistics, a total of 181 people died of dengue fever in Myanmar's Yangon region in the past five years alone, out of 19,000 such cases occurring in the region during the half decade.According to earlier report, the number of people infected with dengue fever in the whole country in 2009 amounted to 3,129 with 37 deaths registered.However, according to the Yangon City Development Committee, the city saw less dengue fever occurrence in 2010 with death rate reducing to one percent in the year from over six percent in 1970.Meanwhile, the Myanmar health authorities are stepping up preventive measures against dengue fever in this sensitive rainy season by extending injection to people.The authorities are also introducing medicine with better effect, combating larva, giving education talks on the prevention and control especially in markets.Dengue fever mostly infected under-15 children, especially those between three and nine years old, but now such disease had also been found among some adult people, the authorities said, warning that dengue fever occurs regardless of age and season.Myanmar, along with Indonesia and Thailand, suffers dengue outbreak most in Southeast Asia region that makes up 52 percent of the dengue-prone areas in the world.

BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added

BEIJING, Nov. 22 (Xinhuanet) -- Underweight patients may have more possibilities of mortality within 30 days of general and vascular surgery compared with mildly obese patients, according to a research published online in Archives of Surgery Tuesday.Researchers at the U.S. National Surgical Quality Improvement Program conducted the research for the years 2005 and 2006, and assessed the contribution of BMI (Body Mass Index) to 189,533 postsurgeries morbidity and mortality by obesity classes.They found that compared with the middle BMI quintile group, patients with BMI value below 23.1, had greater chances for death. For the highest BMI quintile group, higher mortality rate was also observed.However, the researchers also found that obesity may as well be associated with increased mortality for some individual types of surgeries."These individual types of procedures include procedures with which the general surgeon should have definite experience: colorectal resection, colostomy formation, cholecystectomy, hernia repair, mastectomy, and wound debridement," said George J. Stukenborg, PhD, of the University of Virginia inCharlottesvilleand his colleagues.Based on a 30 –day morbidity and mortality risk calculation, the sample patients were categorized into BMI quintile ranges. BMI value of less than 23.1 was considered as lowest, values from 26.3 to 29.6 considered as the middle quintile, and above 35.2 considered as the highest.Factors such as lack of enough data on nonfatal complications and hospital resources, or examining mortality over the 30-day baseline, may cause limitations and inaccuracy to the research and more studies on a wider range of patients in terms of BMI are needed to further confirm the current conclusion, researchers said.
