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, Dec. 31 (Xinhua) -- In a New Year's address broadcast on Saturday, Chinese President Hu Jintao vowed that China will continue to develop friendly exchanges with other countries and positively participate in international cooperation on global issues.While addressing domestic and overseas audiences via state TV and radio broadcasters, Hu urged the acceleration of the transformation of the country's economic development pattern and structural adjustments while making more efforts in ensuring people's livelihood.The country will continue to balance maintaining steady and relatively fast economic growth with adjusting its economic structures and managing inflation expectations, he said in the speech titled "Jointly Improve World Peace and Development," which was broadcast by China Radio International, China National Radio and China Central Television.A photo released on Dec. 31, 2011 shows Chinese President Hu Jintao delivering a New Year address, titled "Jointly Improve World Peace and Development", to domestic and overseas audiences via state TV and radio broadcasters.China will stick to the guidelines of "one country, two systems," "Hong Kong people governing Hong Kong," "Macao people governing Macao," and a high degree of autonomy in maintaining the long-term prosperity and stability of Hong Kong and Macao, Hu said."We will adhere to the principles of 'peaceful reunification' and 'one country, two systems,' continue to push forward the peaceful development of cross-Strait relations, ensure the basic benefits for those of the Chinese nationality, and endlessly work for the common benefit of the compatriots on both sides of the Taiwan Strait," he said.2011 was the first year of the country's 12th Five-Year Plan period (2011-2015). In the face of complicated international situations and arduous tasks in maintaining domestic reform, development and stability, Chinese people united and continued to push forward the opening up and reform drive and the socialist modernization construction, while maintaining steady and relatively fast economic growth and making progress in building a well-off society in an all-around way, he said.China was also actively engaged in international cooperation to boost the growth of the global economy and financial stability, and it was involved in resolving international and regional issues, he said.The world is currently witnessing multipolarization and globalization, and various countries are increasingly interdependent, Hu said."However, the instability and uncertainty of the world economic recovery is on the rise, international and regional hot-topic issues have cropped up one after another, and the peace and development of the world faces unprecedented opportunities and challenges," Hu said.China will stick to peace, development and cooperation, adhere to independent foreign policy, maintain world peace and promote common development, Hu said.The country will stick to the principle of mutual benefit when opening itself up, he said."We will develop friendly cooperations with all countries on the basis of the five principles of peaceful co-existence, and we will continue to actively participate in international cooperation on global issues," Hu said."I believe that as long as people from all countries make efforts hand-in-hand, the world will have a better future and the welfare of the people of all countries will improve," Hu said.An article by Hu on boosting the country's cultural development will be published in Qiu Shi (Seeking Truth), an official magazine of the Communist Party of China Central Committee, on Jan. 1.

BAGHDAD, Nov. 15 (Xinhua) -- Iraqi President Jalal Talabani told the newly-arrived Chinese ambassador Tuesday that Iraq is willing to expand cooperation and strengthen ties with China.Talabani made the statement when receiving the credential from Ni Jian, China's new ambassador to Iraq, in his presidential palace.The friendship between Iraq and China can be traced back to more than a millennium ago and endured the test of time, Talabani said.The recent years have seen increasing cooperation and exchanges between the two countries in multiple fields, bearing positive results and breakthroughs, he said.Ni Jian said that China attaches great importance to the Chinese-Iraqi relations and is willing to broaden friendly ties with Iraq on the basis of equality and mutual benefit.

WASHINGTON, Oct. 3 (Xinhua) -- The Rockefeller University confirmed Monday its Canadian-born cell biologist Ralph Steinman died three days before being awarded the Nobel Prize on Monday as the Nobel committee was unaware of his death at the time."Steinman passed away on September 30," the New York university said in a statement."He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design."The Nobel committee was unaware of Steinman's death when announcing this year's winners and it was unclear whether the prize would be rescinded because Nobel statutes don't allow posthumous award."The Rockefeller University is delighted that the Nobel Foundation has recognized Ralph Steinman for his seminal discoveries concerning the body's immune responses," says Rockefeller University President Marc Tessier-Lavigne."But the news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago after a long battle with cancer. Our thoughts are with Ralph's wife, children and family.""We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," says Steinman's daughter Alexis. "He devoted his life to his work and his family, and he would be truly honored.""Ralph's research has laid the foundation for numerous discoveries in the critically important field of immunology, and it has led to innovative new approaches in how we treat cancer, infectious diseases and disorders of the immune system," Tessier-Lavigne says.Steinman, who discovered the immune system's sentinel dendritic cells, is this year's recipient of the Nobel Prize in Physiology or Medicine. He shares half the prize with Bruce Beutler and Jules Hoffmann.

BEIJING, Nov. 13 (Xinhua) -- A campaign that aims to boost the public's role in safeguarding food safety and promote awareness of the issue was launched at the 9th China Food Safety Annual Conference, which closed on Sunday.Food safety has a bearing on people's health as well as the nation's sound and harmonious development, said Shi Xiushi, chairman of the Financial and Economic Committee of China's National People's Congress (NPC), at the opening, calling for efforts to raise companies' sense of responsibility and consumers' awareness in preventing and dealing with food safety crimes.The new campaign is part of a broader five-year program (2011-2015) of food safety education announced by the State Council Food Safety Commission (SCFSC) in May.The program aims for more than 80 percent of the public to be aware of basic food safety by 2015, with the rate for primary and high-school students reaching up to 85 percent or more.ARDUOUS WORKFood safety has become a growing public concern in China following a string of scandals over recent years. In the latest one, illegal workshops were found making and selling "gutter oil," which is processed from leftovers dredged from gutters.Gu Xiulian, former vice chairwoman of the NPC's Standing Committee, the country's top legislature, said ensuring safety is the top priority for the food sector, the country's pillar industry with an output of 550 million yuan (97.3 million U.S. dollars) in the first nine months of 2011.The development of the nation's food safety has failed to keep up with the demands of a public whose living standards have improved substantially in recent years, said Shi.Pledging to do everything it can to ensure food safety, the government takes a zero-tolerance approach to companies that sell unsafe food. In 2010 alone, authorities across the country investigated and handled 130,000 cases of food safety violations, shutting down more than 100,000 companies, according to the SCFSC."The food industry's overall development level is relatively low. There are weak links in the sector's credibility, management, detection techniques and even the laws and regulations," said Pu Changcheng, deputy director of the Administration of Quality Supervision, Inspection and Quarantine.Pu's points are exemplified by China's agricultural industry, which is largely based around small-scale production managed by disparate bodies. It would be a formidable task to eradicate the sector's safety issues.The catering business also faces a similar plight. The country has issued licenses to 2.2 million catering companies, most of which are small and individually operated, making safety supervision extremely difficult, according to Bian Zhenjia, deputy head of the State Food and Drug Administration.
