GENEVA, Aug. 19 (Xinhua) -- The World Health Organization (WHO) and the UN Children's Fund (UNICEF) started an emergency vaccination campaign in all accessible areas of South and Central Somalia, WTO spokesperson Tarek Jasarevic said here on Friday.In July 2011 alone, 1,019 suspected measles cases and 31 related deaths were reported in South and Central Somalia, representing 20 percent of all reported cases for this year.The major factors for a measles outbreak in Somalia are low coverage, malnutrition, population movements, and overcrowed internally displaced (IDP) camps."WHO fears that the measles outbreak could affect a high number of people, especially among the vulnerable IDPs whose overall health is already fragile," Jasarevic said.About 2.5 million children aged between 6 and 15 in 10 regions of South and Central Somalia, including children in Mogadishu, will be targeted during this campaign.

LOS ANGELES, July 5 (Xinhua) -- NASA's Juno spacecraft is 30 days away before its first launch window opens, the Jet Propulsion Laboratory (JPL) announced on Tuesday."One month from today, our first launch window opens at 11:34 a. m. EDT (8:34 a.m. PDT) and lasts 69 minutes," said Jan Chodas, Juno project manager from NASA's JPL in Pasadena, Los Angeles."Our primary launch period is 22 days long, and so if weather or other issues come up on Aug. 5, we have 21 more days to get Juno flying. Once we get Juno into space, it's a five-year cruise to Jupiter.""The launch window is the length of time allotted every day for an attempt to launch the spacecraft," said Chodas. "The launch period is the period of time in days when everything is in the right place to get your mission off to the right start."For a mission like Juno, getting everything in the right place includes considering the size of the rocket and spacecraft, where our home planet -- and in particular Juno's launch pad -- is pointed at any moment, and its location in space relative to other celestial objects like Juno's final target, Jupiter.Juno is scheduled to launch aboard a United Launch Alliance Atlas V rocket from pad 41-C at the Cape Canaveral Air Force Station, Florida.The solar-powered spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere and investigate the existence of a solid planetary core.JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska. Lockheed Martin Space Systems, Denver, built the spacecraft.

LOS ANGELES, June 9 (Xinhua) -- The edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles approximately 100 million miles (160 million kilometers) wide, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.The finding was based on observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, said JPL in Pasadena, Los Angeles.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles which are created when magnetic field lines reorganize, said JPL.The new model suggests the field lines are broken up into self- contained structures disconnected from the solar magnetic field, according to JPL."The sun's magnetic field extends all the way to the edge of the solar system," said astronomer Merav Opher of Boston University. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Like Earth, our sun has a magnetic field with a north pole and a south pole. The field lines are stretched outward by the solar wind, a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.Understanding the structure of the sun's magnetic field will allow scientists to explain how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.The Voyager spacecraft, more than nine billion miles (14 billion kilometers) away from Earth, are traveling in a boundary region. In that area, the solar wind and magnetic field are affected by material expelled from other stars in our corner of the Milky Way galaxy.Launched in 1977, the Voyager twin spacecraft have been on a 33- year journey. They are en route to reach the edge of interstellar space. JPL built the spacecraft and continues to operate them.

XICHANG, Sichuan, June 21 (Xinhua) -- China successfully launched a new communication satellite, the Zhongxing-10, from its Xichang Satellite Launch Center in southwest Sichuan Province on early Tuesday.The satellite, carried by a Long March-3B rocket carrier, blasted off from the center at 0:13 a.m., said a statement from the center.According to statistics from the control center, the satellite successfully separated from its carrier rocket and entered Earth's orbit as scheduled, 26 minutes after being launched.The Zhongxing-10 was designed and manufactured by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation.The satellite will provide communication, broadcasting and data transmission services for users in China and the Asia-Pacific region. It will replace the Zhongxing-5B satellite, which was launched in 1998.The launch was the 138th mission for the Long March carrier rocket series.

WELLINGTON, Aug. 30 (Xinhua) -- Middle-aged women who wolf down their meals are much more likely to be overweight or obese than women who eat slower, New Zealand research has found.In what they claimed to be the first such nationwide study anywhere, Otago University researchers analyzed the relationship between self-reported speed of eating and body mass index (BMI) in more than 1,500 New Zealand women aged 40 to 50, an age group known to be at high risk of weight gain.The study by the university's department of human nutrition could lead to new and more successful methods of treating obesity, say the researchers.Study principal investigator Dr Caroline Horwath said that after adjusting for factors such as age, ethnicity, smoking, physical activity and menopause status, the researchers found that the faster women reported eating, the higher their BMI.Results from the two-year follow-up were expected to be published next year, and if analysis confirmed a causal relationship, the researchers would test interventions that focused on encouraging women to eat more slowly.
