MOSCOW, June 27 (Xinhua) -- Russia successfully launched a Cosmos class military satellite on Monday, said spokesman of the Russian Space Forces Alexei Zolotukhin.A Soyuz-U carrier rocket carrying the military satellite blasted off from the Plesetsk Plesetsk space center in northern Russia at 20:00 Moscow time (1600 GMT), Zolotukhin said."The rocket put the Cosmos series military satellite into the designated orbit at 20:08 Moscow time (1608 GMT)," he added.The spokesman also said the launch of the Soyuz-U carrier rocket "was the first time for this type of rockets" in this year.The launch carried out by a team from the Russian Space Forces was supervised by Space Forces Commander Oleg Ostapenko.The satellite, Cosmos-2472, is a new member to a Russian network of about 60-70 military reconnaissance satellites.

LOS ANGELES, July 22 (Xinhua) -- Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe, NASA's Jet Propulsion Laboratory (JPL) said on Friday.The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away, according to JPL in Pasadena, California."The environment around this quasar is very unique in that it's producing this huge mass of water," said Matt Bradford, a scientist at JPL. "It's another demonstration that water is pervasive throughout the universe, even at the very earliest times. "This artist's concept illustrates a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. Gas and dust likely form a torus around the central black hole, with clouds of charged gas above and below. X-rays emerge from the very central region, while thermal infrared radiation is emitted by dust throughout most of the torus. While this figure shows the quasar's torus approximately edge-on, the torus around APM 08279+5255 is likely positioned face-on from our point of view.A quasar is powered by an enormous black hole that steadily consumes a surrounding disk of gas and dust. As it eats, the quasar spews out huge amounts of energy. Both groups of astronomers studied a particular quasar called APM 08279+5255, which harbors a black hole 20 billion times more massive than the sun and produces as much energy as a thousand trillion suns.Astronomers expected water vapor to be present even in the early, distant universe, but had not detected it this far away before. There's water vapor in the Milky Way, although the total amount is 4,000 times less than in the quasar, because most of the Milky Way's water is frozen in ice. Water vapor is an important trace gas that reveals the nature of the quasar. In this particular quasar, the water vapor is distributed around the black hole in a gaseous region spanning hundreds of light-years in size (a light-year is about six trillion miles).Its presence indicates that the quasar is bathing the gas in X- rays and infrared radiation, and that the gas is unusually warm and dense by astronomical standards, JPL said.Although the gas is at a chilly minus 63 degrees Fahrenheit ( minus 53 degrees Celsius) and is 300 trillion times less dense than Earth's atmosphere, it's still five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way, said JPL.Measurements of the water vapor and of other molecules, such as carbon monoxide, suggest there is enough gas to feed the black hole until it grows to about six times its size, JPL said.Whether this will happen is not clear, the astronomers say, since some of the gas may end up condensing into stars or might be ejected from the quasar.Bradford's team made their observations starting in 2008, using an instrument called "Z-Spec" at the California Institute of Technology's (Caltech's) Submillimeter Observatory, a 33-foot (10- meter) telescope near the summit of Mauna Kea in Hawaii. Follow-up observations were made with the Combined Array for Research in Millimeter-Wave Astronomy (CARMA), an array of radio dishes in the Inyo Mountains of Southern California.The second group, led by Dariusz Lis, senior research associate in physics at Caltech and deputy director of the Caltech Submillimeter Observatory, used the Plateau de Bure Interferometer in the French Alps to find water. In 2010, Lis's team serendipitously detected water in APM 8279+5255, observing one spectral signature.Bradford's team was able to get more information about the water, including its enormous mass, because they detected several spectral signatures of the water, according to JPL.

WASHINGTON, Aug. 2 (Xinhua) -- Breastfeeding protects against childhood obesity, but less than 4 percent of U.S. hospitals provide the full range of support mothers need for breastfeeding, according to a report issued by the Centers for Disease Control and Prevention Tuesday.Improving rates of breastfeeding by providing better hospital support to mothers and babies is an important strategy to improve children's health, including a reduced risk of childhood obesity, the monthly Vital Signs report said."Hospitals play a vital role in supporting a mother to be able to breastfeed," it said."Those first few hours and days that a mom and her baby spend learning to breastfeed are critical. Hospitals need to better support breastfeeding, as this is one of the most important things a mother can do for her newborn. Breastfeeding helps babies grow up healthy and reduces health care costs," it added.The report found only 14 percent of hospitals have a written and model breastfeeding policy.It also found in nearly 80 percent of hospitals, healthy breastfeeding infants are given formula when it is not medically necessary, a practice that makes it much harder for mothers and babies to learn how to breastfeed and continue breastfeeding at home.Additionally, only one-third of hospitals practise rooming in, which helps mothers and babies learn to breastfeed by allowing frequent chances to breastfeed.Finally, the report found in nearly 75 percent of hospitals, mothers and babies don't get the support they need when they leave hospitals, including a follow-up visit, a phone call from hospital staff and referrals to lactation consultants, and other important support systems in their communities.

WASHINGTON, June 9 (Xinhua) -- Observations from NASA's Voyager spacecraft suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles, the U.S. space agency said Thursday in a statement.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles approximately 100 million miles wide. The bubbles are created when magnetic field lines reorganize. The new model suggests the field lines are broken up into self-contained structures disconnected from the solar magnetic field. The findings are described Thursday in the Astrophysical Journal.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 or a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.The Voyager spacecraft, more than nine billion miles 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."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."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.So far, much of the evidence for the existence of the bubbles originates from an instrument aboard the spacecraft that measures energetic particles. Investigators are studying more information and hoping to find signatures of the bubbles in the Voyager magnetic field data."We are still trying to wrap our minds around the implications of the findings," said University of Maryland physicist Jim Drake, one of Opher's colleagues.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. NASA's Jet Propulsion Laboratory built the spacecraft and continues to operate them.

BEIJING, July 13 (Xinhuanet) -- Gasoline powers vehicles all around the world, but a sick Chinese man has been drinking the sticky liquid for 42 years under the illusion that it can relieve his physical pain.Chen Dejun, 71, lives by himself in shabby thatched cottage on a hill in Shuijiang township, Nanchuan district of southwest China's Chongqing municipality. The short and bony man said he drinks 3 to 3.5 kilograms of gasoline every month, which he buys from a station at the foot of the hill.Chen is known locally as a stonecutter and master of weaving bamboo with a good business sense. But he’s also known for his undying love of drinking gasoline.He developed the habit back in 1969 when he suddenly began coughing and felt pain in his chest. Seeing no progress after trying some medicine, he took up the folk remedy of drinking kerosene, Chongqing Evening News reported.It turned out to be helpful for him after the first sip, and he since became addicted to kerosene. Then he moved on to gasoline.Chen said it is hard to calculate exactly how much gasoline he has swallowed throughout his life, but the newspaper reported Chen has consumed an estimated 1.5 tons over the past 42 years.Chen's wife Yuan Huibi and their three sons tried many times to stop Chen's addiction to gasoline, but those efforts only made the family relations tense. Eight years ago Chen moved to the cottage to live alone.Sources from Honglou Hospital in Chongqing said Chen‘s health is fine despite having symptoms of emphysema. Chen refused to receive free check ups from the hospital.Feng Fu, an associate professor with the Second Hospital Affiliated to Chongqing Medical University, said Chen may have developed some resistance to gasoline. Otherwise, Feng said, it would be impossible for Chen to live. Feng also said gasoline may only work as anaesthetic for Chen but can’t cure his pain.
