BEIJING, May 16 (Xinhuanet) -- NASA is close to deciding on a landing site for its Mars rover Curiosity mission by narrowing the choices to four, media reports said Monday.Scientists in the close-knit Mars research community get one last chance to make their case this week when they gather before the "judges" — the team running the 2.5 billion U.S. dollar mission that will soon suggest a landing site to NASA, the ultimate decider."All four of these places are compelling places on Mars to study. There's not a loser among them," said landing site scientist Matt Golombek of the NASA Jet Propulsion Laboratory, one of the meeting's leaders.The mission will use rover Curiosity to study whether a selected area will have environmental conditions suitable for life and for preserving evidence about whether extraterrestial life has existed.Being nuclear-powered, the rover cannot go to a location that has either water or ice within one meter of the surface.The size of a mini Cooper, Curiosity is scheduled to launch in late November after a two-year delay.

TIANJIN, April 16 (Xinhua) -- As China tries to establish a universal medicare umbrella, its first move to offer treatment to all the hemophilia patients in the country is to know their population and where they are.China's national hemophilia information management center registered 7,980 cases nationwide since its establishment last year in a bid to provide reference for making national treatment policies and medicine production quota, said the center officials Saturday.Yang Renchi with the center and the Chinese Academy of Medical Sciences, said that the patient information database will help the government make hemophilia-related medical and social welfare policies, optimize resources and guide the manufacturing of drugs such as coagulation factor VIII.The information center, created by the Ministry of Health, is located in the Blood Diseases Hospital of the Chinese Academy of Medical Sciences in the port city Tianjin in north China.Hemophilia is a rare genetic bleeding disorder that prevents the blood from clotting properly, resulting in easy bruising and prolonged bleeding from trauma. Lack of treatment can lead to permanent disabilities or even death.China is estimated to have roughly 100,000 hemophilia patients."Be inspired; get involved in Treatment for All" is the theme for the 22nd World Hemophilia Day, which falls on Sunday, April 17."A necessary precondition for 'Treatment for All' is to know the clinical information and location of each case," said Yang, "and this is exactly what the information system does."In addition, China plans to establish hospital-based provincial hemophilia management centers within five years across the country to register and monitor patients and standardize disease diagnosis and treatment under the information system.SHORTAGE OF DRUGSBlood-derived coagulation factor VIII and recombinant coagulation factor VIII are two effective drugs which are vital for hemophiliacs. However, the drugs are expensive and produced in limited quantities, a difficulty which hundreds of thousands of hemophiliacs in China have to confront.According to Yang, the minimum dose of coagulation factor VIII for prevention of bleeding episodes is two international units (IU) per kg of weight a day. A 50-kg hemophilia patient needs at least 36,500 IU of factor VIII every year to prevent bleeding."Each IU of blood-derived coagulation factor VIII costs about 3 yuan(0.46 U.S. dollars) and the annual cost is almost 120,000 yuan. The recombinant one is almost twice the price," said Yang.Only four drug firms are qualified to manufacture blood-derived coagulation factor VIII in China. The national output in 2010 was 400,000 vials (200 IU per vial) which means 80 million IU for the entire country.Wu Runhui, a hematology specialist with the Beijing Children's Hospital, said that the minimum dose is only for the prevention of bleeding episodes which are required to keep the patient alive. For the hemophiliac to live a regular lifestyle, 3,000 IU per kilo a year is needed, which would cost half a million yuan a year."Even in the most developed countries, a hemophiliac cannot survive without supportive medical policies and social welfare system," said Wu.

BEIJING, Apirl 1 (Xinhuanet) -- An Ariane rocket launch of two communications satellites was aborted Wednesday after a technical hitch at the scheduled moment of liftoff in French Guiana on Wednesday.According to Arianespace, the Ariane 5 rocket's Vulcain main engine ignited as scheduled at 5:45 pm EDT (21:45 GMT), but the checkout process during ignition detected an unspecified anomaly, shutting down the engine before the two solid-rocket boosters ignited.The 165-foot (50-meter) tall Ariane 5 rocket's main engine's checkout process "was not completed successfully, preventing the boosters' ignition and thereby aborting the mission," Arianespace officials said. "The Ariane 5 and its two payloads remain in a safe mode on the launch pad."The Ariane 5 rocket uses a Vulcain 2 first stage engine assisted by two solid rocket boosters to launch satellite payloads into orbit. The Vulcain 2 engine is fueled by cryogenic liquid hydrogen and liquid oxygen and is designed to burn for about 600 seconds to boost payloads into space.Jean-Yves Le Gall, Arianespace president, said it would return the rocket to the final assembly building to prepare it for another launch attempt while investigating the cause of the problem. No new launch date was immediately announced.The Ariane 5 was to launch the Yahsat Y1A and Intelsat New Dawn communications satellites.

BEIJING, Jan. 21 (Xinhua) -- Chinese Vice Premier Li Keqiang on Friday stressed the importance that local governments improve management of land and resources, as it remains vital for the stable and relatively quick development of the nation's economy.Li said China faced the difficult tasks of land and resource management as resources are becoming scarce amid the country's quickening industrialization, urbanization, and agricultural modernization.He said the nation must continue preserving arable land. To ensure grain security, China set a "red line" to guarantee its arable land never shrinks to less than 1.8 billion mu (120 million hectares).Chinese Vice Premier Li Keqiang (R) shakes hands with outstanding representatives from local departments in charge of land and resources in Beijing, capital of China, Jan. 21, 2011.Li also called on local authorities to step up efforts to protect valuable mineral resources while using resources more efficiently and in a frugal manner.At the same time, the senior Chinese official said land should be guaranteed for the nation's plan to build 10 million affordable houses for low and middle income people this year.Further, Li urged local authorities to improve work in monitoring and taking precautionary measures against geological disasters to ensure the safety of people's lives and property.
