CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao on Thursday urged the world's major economies to work together to promote growth and financial stability."It is imperative that we stand on a higher plane, transcend differences on specific issues, move beyond short-term considerations, and jointly seek ways to overcome the crisis and sustain development," Hu told the Group of 20 (G20) summit here."At this critical moment, the G20 must work to address the key problems, boost market confidence, defuse risks and meet challenges and promote global economic growth and financial stability," said Hu.As the premier forum for international economic cooperation, the G20 must continue to demonstrate the spirit of standing together in times of adversity and pursuing win-win cooperation, he said.The Chinese president said "the current world economic situation deserves our high attention," cautioning the global recovery is fraught with instability and uncertainty and faces growing risks and challenges.Some major economies are experiencing economic slowdown and some countries are facing acute sovereign debt problems, said Hu.He also cited volatility in the international financial markets, and high inflationary pressure in emerging markets.Hu put forward a five-point proposal on what G20 nations need to do to tide over the crisis.First, the countries should ensure growth while paying attention to balance. Given the serious risks facing the global economy and continued market volatility, ensuring growth and promoting stability should be the top priority, he said."We should introduce new and strong measures to ensure that fiscal and monetary policies are fully implemented and that funding is channeled into the real economy to boost production and employment."Second, the G20 nations should strengthen unity and send a strong signal to the world as there is widespread panic and acute lack of confidence in the markets, said Hu.He urged G20 members to strengthen consultation and coordination, tackle sovereign debt risks, regulate cross-border capital flow, put the fluctuation of commodity prices under control, mitigate global inflationary pressure and make sure that the economic policies pursued by various countries do not offset each other.Third, global economic governance should be improved through reform, Hu said.The international financial crisis has highlighted the deficiencies in the global economic governance system, said Hu."Major efforts should be made to reform and improve the international monetary system, international trading system and commodity pricing mechanism," said the Chinese president.

BEIJING, Jan. 24 (Xinhua) -- China's meteorological authority said Tuesday that the country's northern regions will continue to have sunny weather for the coming 24 hours, while the south will see subdued rain and snow.Temperatures in most parts of the country are expected to rebound slightly, the National Meteorological Center said in a statement on its website.But the lowest temperatures in the areas south of the Yangtze River will remain around zero degree Celsius, the center said.Meanwhile, rain and snow will subdue in most parts of the southern regions over the next three days, although freezing rain is forecast to hit Guizhou and Hunan provinces, according to the statement.

RIO DE JANEIRO, Dec 15 (Xinhua) -- Brazilian President Dilma Rousseff Thursday signed a law banning smoking in public spaces and tobacco advertising at sale places in his country.Smoking in all enclosed public spaces, defined as free access areas used simultaneously by several people, is forbidden in the new law.It also prohibits tobacco advertising such as posters or banners at sale places. Previously the ban was only imposed on TV, radio and billboards advertising.In addition, the law increases the taxes and establishes minimum prices over the tobacco products to discourage buyers, therefore the cigarettes prices are expected to increase 20 percent in 2012 and 55 percent by 2015.Health warnings are also required on both sides of cigarette packs to alert consumers about the consequences of their smoking habit.The law is welcomed by some anti-smoking groups."In addition to protecting the health of its citizens, Brazil has also set an example for the world," said Matthew Myer, president of Campaign for Tobacco-Free Kids.

  

WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.

  

CAPE TOWN, Nov. 13 (Xinhua) -- The research vessel SA Agulhas has set off from Cape Town on a 10-day polar tour intended to promote dialogue on climate change, authorities confirmed on Sunday.The trip was designed to mark the 17th Climate Conference of the Parties (COP17) to be held in Durban later this month, according to the Department of Environmental Affairs.The voyage, which set off Saturday noon with scientists, academics, students and journalists aboard, would host exhibitions, symposiums and lectures from climate change scientists on the work of the polar research vessel, spokesman Zolile Nqayi said in a statement.The exhibitions and lectures would also highlight the various scientific activities undertaken by the department and its partners in Antarctica and the Southern Oceans, according to the South African Press Association (SAPA).Apart from her research and supply work, the Agulhus also helped to rescue the Magdalena Oldendorff, which became stuck in thick ice in June 2002.In December the SA Agulhas would make its final voyage to Antarctica before retirement.The Agulhas, which has been in service for 33 years, would be replaced by a new vessel under construction in Finland."She served us very well," said Dr Monde Mayekiso, deputy director general of oceans and coasts."The new vessel will have enhanced technologies and capabilities to further understand the ocean environment and to bring that understanding to an increasing number of South Africans, " he said.
