ADDIS ABABA, Dec. 1 (Xinhua) -- Marking the World AIDS Day on Thursday at the African Union (AU) headquarters in Addis Ababa, Ethiopia, Jean Ping, the AU Commission chairperson, said Africa should no longer see new generations with HIV infection.Through his representative, Ping called upon individual and collective action to contain mother to child transmission of HIV."We should act individually and collectively not only to prevent mother to child transmission but also to take care of the health of people living with the virus," said the chairperson.He also expressed commitment of the AU Commission to work with member states and pertinent bodies in the efforts made to HIV treatment and prevention.The World AIDS Day is commemorated this year under the theme "Zero Mother to Child Transmission", as world leaders who were gathered in New York for the 2011 United Nations (UN) High Level Meeting on AIDS in June, launched a Global Plan for significant strides towards eliminating new HIV infection among children by 2015 and keeping their mothers alive.Remarkable progress has been made so far, which is proof to realize the vision of zero new HIV infection, zero discrimination, and zero AIDS-related death (the three zeros), said UN Secretary General Ban Ki-moon in the message on the commemoration of the World AIDS Day.The secretary general revealed that the number of new infections has fallen by more than 20 percent since 1997, and new infections are continuing to decline in most parts of the world.In sub-Saharan Africa, the region most affected by the AIDS epidemic, HIV incidence has decreased in 22 countries, he said.According to UNAIDS, Ethiopia, Nigeria, South Africa, Zambia, and Zimbabwe are among the African countries where new HIV infections dropped significantly."Treatment has averted 2.5 million AIDS-related deaths since 1985. Last year alone, 700,000 lives were saved. Some 6.6 million people, nearly half those who need treatment in low and middle- income countries, are now receiving it," said Ban."Synergies between prevention and treatment are speeding up progress. But, to end AIDS, we need to deliver even greater results," said the secretary general.The UNAIDS says to get to the three zeros there must be acceleration on smart investments, capitalizing on scientific advancements and respecting human rights.Speaking at the AU headquarters on the commemoration of AIDS Day, Jan Beagle, deputy executive director of UNAIDS, underlined on the need to invest smartly to achieve the vision of the three zeros.There is a global target of 22 million U. S. dollars to 24 billion dollars to fund the AIDS response, which the UNAIDS says is a shared responsibility of all countries, donors and others."International assistance for the AIDS response has declined from 8.7 billion dollars in 2009 to 7.6 billion in 2010," said the Deputy Executive Director."We need to use new technology more effectively to reduce costs and demonstrate that we can deliver return on investment," she said.The AIDS movement is a movement for inclusiveness, equity and social justice, she said, adding that it has demonstrated global solidarity is possible to address multi-sectoral challenges.According to Abdoulie Janneh, executive secretary of the UN Economic Commission for Africa (ECA), an estimated 7,000 people get infected with HIV infections every day.The executive secretary highlighted ingenious and novel approaches in introducing new HIV/AIDS prevention strategies."A combination of the traditional initiatives and innovative initiatives can all be used to eliminate new HIV infections," said Janneh.

WASHINGTON, Dec. 20 (Xinhua) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system, the U.S. space agency announce Tuesday.The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun, according to NASA.The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1, 000 light-years away in the constellation Lyra.Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass."The primary goal of the Kepler mission is to find Earth-sized planets in the habitable zone," said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, lead author of a new study published in the journal Nature. "This discovery demonstrates for the first time that Earth-size planets exist around other stars, and that we are able to detect them."The Kepler-20 system includes three other planets that are larger than Earth but smaller than Neptune. Kepler-20b, the closest planet, Kepler-20c, the third planet, and Kepler-20d, the fifth planet, orbit their star every 3.7, 10.9 and 77.6 days. All five planets have orbits lying roughly within Mercury's orbit in our solar system. The host star belongs to the same G-type class as our sun, although it is slightly smaller and cooler.

BEIJING, Jan. 9 (Xinhua) -- China's official website for booking train tickets received a daily average of more than 1 billion hits during the first week of January, according to a railway official.Hu Yadong, vice minister of railways, said Sunday that the online ticket sales platform has provided consumers with a convenient way to buy tickets. He also addressed complaints about the fairness of the sales process."Train tickets sold online or by telephone have topped 2 million daily, meaning that around one-third of passengers don't have to wait in line at train stations for several hours to get a ticket," Hu said.However, many Chinese have expressed dissatisfaction with the website, with some people unable to get train tickets home for this year's Spring Festival holiday, a major holiday in China.Several customers posted their complaints on popular microblogging website weibo.com, stating that the booking site often failed due to "too many visits at the same time."The Spring Festival holiday is always a difficult time for China's public transportation authorities. A total of 3.16 billion passenger trips are expected during the holiday, up 9.1 percent from a year earlier, of which 235 million trips will be made via the country's railways, up 6.1 percent year-on-year, said Hu.This year's transport rush in the Spring Festival Season started on Sunday and will end on Feb. 16, according to the Ministry of Railways.

BEIJING, Dec. 7 (Xinhua) -- The Chinese government on Wednesday released a white paper on its foreign trade, highlighting the country's achievements in boosting foreign trade and contribution to the world economy.The white paper, titled China's Foreign Trade, was released by the Information Office of the State Council.The white paper introduces China's historic progress, international contribution and policies in foreign trade.

BEIJING, Oct. 13 (Xinhuanet) -- Himalayas may be one of the most potential regions to provide solar power in future, according to a new research by Japanese scientists quoted by media reports Thursday. Deserts are usually regarded as the hotbeds for capturing solar power, but some of the loftiest and coldest regions can receive more energy from the sun than some deserts, said Takashi Oozeki and Yutaka Genchi, authors of the research published in Environmental Science and Technology. To set up solar cells on Himalayas would be challenging. Transmission losses and snowfall should be taken into consideration, said the researchers with the National Institute of Industrial Science and Technology in Japan. Still, the Himalayan region is attractive, because there are large energy demands in the countries nearby."It is near regions with large future energy demands such as China and India," they said.Other cold regions that can receive solar power include Andes of South America and Antarctica, according to the study.
