HOHHOT, Aug. 27 (Xinhua) -- A 5,000-year old rock carving in north China's Inner Mongolia Autonomous Region depicts a falling meteor, said archaeologists on Saturday.A rock on the side of Dahei Mountain in the city of Chifeng has images of people, domed houses and a fire ball with a long tail falling from the sky engraved on it, said Wu Jiacai, head of the Inner Mongolia rock paintings protection association."I believe it shows prehistoric people returning at dusk from a hunting trip to their domed houses, as a meteor falls from the sky," Wu shared his findings at the 6th Hongshan Cultural Forum that runs from August 25 to 27.He added that in the same location several years ago, another set of carvings were found showing people fleeing, snakes slithering and birds flying away, which might be what happened after the meteor hit the earth.The area has about 1000 carvings all believed to be made by the Neolithic Hongshan people, Wu said."The pictures can shed some light on the disappearance of the Hongshan culture, which was quite developed," Wu said.

UNITED NATIONS, June 9 (Xinhua) -- Partners from UN agencies and governments, as well as civil society and the private sector gathered here Thursday to launch "Countdown to Zero: Global plan towards the elimination of new HIV infections among children by 2015 and keeping their mothers alive.""Governments and foundations that support this plan are saying: we treasure all life equally," said UN Secretary-General Ban Ki- moon, who spoke at the event. "We give all people the best possible chance. We provide health care to all who need it."This new plan, which was formulated by a Global Task Team of more than 30 governments and 50 international and national organizations, aims to bring the number of new HIV infections in children to zero by the middle of the decade and help their mothers survive.The launch of Countdown to Zero came on the sidelines of the UN High-Level Meeting on AIDS, which runs from June 8-10, and has been an opportunity for participants to take stock of gains made in combating the disease and to agree on a declaration that will direct the actions of member states to prevent and treat HIV/AIDS over the next five years.Ban told the audience at the launch that history has proven that it is possible to make great strides in fighting HIV/AIDS, with the right amount of effort and coordination."Let us not forget that some regions have nearly achieved no new infections from mother to child," he said. "If we push hard, as we have committed today, with your continued help and with the will to do what is right for the world, we can spread this success to mothers everywhere."According to the Joint UN Program on HIV/AIDS (UNAIDS), the rate of HIV/AIDS transmission from mother to child was been reduced by 26 percent from 2001 to 2009.Former U.S. President Bill Clinton, who spoke at the launch, said that he believes the time to eliminate HIV/AIDS in children is at hand."We are here because we all recognize that the time has finally come to end pediatric AIDS worldwide and we believe we can do it," he said. "We know we have the capacity to produce the medicine, we know that."Clinton emphasized the fact that HIV/AIDS is often prevalent in less developed countries. Sub-Saharan Africa remains the region that has the most HIV/AIDS infected people."There are still too many kids who are born HIV-positive," he said. "Just 22 countries account for 90 percent of those pediatric infections."He said that there are not only moral reasons for wealthier countries to help these nations by investing in their HIV/AIDS responses, but that by doing so they increase their soft power -- influence that utilizes non-coercive measures."I think its important in a world where no one wants to look weak and the military justifiably has a claim on all of our budgets, we not forget that what my secretary-of-state often refers to as soft power issues, they have a bigger impact on our long term security," Clinton said. "I think that accounts in no small measure for the presence of leaders of global corporations here at this meeting today, they know this as well."Collaboration and close coordination of responses to HIV/AIDS, Clinton said, is also essential."There are still too many places where HIV and maternal and child health groups work completely separately," he said. "That dramatically reduces the likelihood that mothers are their babies will receive the full range of care. We simply have to all work together, both within governments and all of those who are trying to help to ensure that mothers get the drugs they should and that their babies are born without the virus."Clinton said that Goodluck Jonathan, president of Nigeria, who gave a statement at the launch as well, is an excellent example of the "strong political leadership and personal commitment" necessary to defeat HIV/AIDS and reach to goals set by the Countdown to Zero plan.In his speech, Jonathan said that Africa is has banded together through the Abuja Declaration, adopted in 2001, which turned attention and resources towards public health problems on the continent, particularly HIV/AIDS."That declaration was to make African countries spend at least 15 percent of their budget on their health sector and a reasonable percentage of this would be geared towards HIV prevention and control," he said.Budgeting shortfalls for fighting HIV/AIDS in Africa must be accounted for, Jonathan said, as African countries must not rely solely on donors to fund their responses."I intend to explore in the coming months in collaboration with colleagues in sub-Saharan Africa an effective and creative funding mechanism to ensure ownership and long terms sustainability of the HIV and AIDS response in Africa," he said.

STOCKHOLM, Aug. 30 (Xinhua) -- Meat diet, a dietary habit popular in some developed countries, can produce more greenhouse gas and thus is likely to actually cause more impact on climate, said a Swedish study published Tuesday.According to Swedish Radio's Ekot news program, the meat diet, also known as Low Carb High Fat (LCHF) diet, doubled the greenhouse gas emission compared with the balanced diet recommended by the Swedish Food Administration.Many Swedish people have abandoned the diet habit of eating root vegetables and fruits, and switched to LCHF diets. The LCHF diet has more meat, fat and unusual greenhouse gas emission. But these root vegetables, such as potatoes and carrots, and other naturally grown vegetables can be planted with less greenhouse gas emission.The report also revealed that many of the LCHF diet advices are actually given by the researchers sponsored by meat industry.

MOSCOW, June 15 (Xinhua) -- Russia's Mission Control announced on Wednesday it had raised the International Space Station (ISS) by 10.2 km to 374.7 km with the help of the Europe's ATV-2 Johannes Kepler.The Mission Control conducted the correction to the ISS at 19: 55 Moscow time (1555 GMT) by the boosters of the ATV-2 Johannes Kepler. The correction had lasted for some 40 minutes.According to the Mission Control, the correction was made in line with the ISS's ballistic flight program.On June 12, the Europe's second Automated Transfer Vehicle (ATV) Johannes Kepler has conducted two similar operations, raising the ISS orbit by 19.2 km to 364.6 km.Corrections to the space station's orbit are conducted periodically before launches of Russian cargo ships and U.S. shuttles to compensate for the Earth's gravity and to safeguard successful dockings.According to the Mission Control, the ATV-2 Johannes Kepler is scheduled to undock from the ISS on June 21.

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.
