WASHINGTON, Dec. 5 (Xinhua) -- NASA's Kepler mission has confirmed its first planet in the "habitable zone," a region where liquid water could exist on a planet's surface, the U.S. space agency announced on Monday.The newly-confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to Sun. The planet is about 2.4 times the radius of Earth. Scientists don't yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.Previous research hinted at the existence of near-Earth-size planets in habitable zones, but clear confirmation proved elusive. Two other small planets orbiting stars smaller and cooler than Sun recently were confirmed on the very edges of the habitable zone, with orbits more closely resembling those of Venus and Mars.Kepler-22's star is a bit smaller than our sun, so its habitable zone is slightly closer in. The diagram shows an artist's rendering of the planet comfortably orbiting within the habitable zone, similar to where Earth circles the sun. Kepler-22b has a yearly orbit of 289 days. The planet is the smallest known to orbit in the middle of the habitable zone of a sun-like star. It's about 2.4 times the size of Earth."This is a major milestone on the road to finding Earth's twin, " said Douglas Hudgins, Kepler program scientist at the NASA Headquarters in Washington. "Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe."Kepler discovers planets and planet candidates by measuring dips in the brightness of more than 150,000 stars to search for planets that cross in front, or "transit," the stars. Kepler requires at least three transits to verify a signal as a planet."Fortune smiled upon us with the detection of this planet," said William Borucki, Kepler principal investigator at the NASA Ames Research Center who led the team that discovered Kepler-22b. "The first transit was captured just three days after we declared the spacecraft operationally ready. We witnessed the defining third transit over the 2010 holiday season."The Kepler science team uses ground-based telescopes and the Spitzer Space Telescope to review observations on planet candidates the spacecraft finds. The star field that Kepler observes in the constellations Cygnus and Lyra can only be seen from ground-based observatories in spring through early fall. The data from these other observations help determine which candidates can be validated as planets.Kepler-22b is located 600 light years away. While the planet is larger than Earth, its orbit of 290 days around a Sun-like star resembles that of Earth. The planet's host star belongs to the same class as Sun, called G-type, although it is slightly smaller and cooler.Of the 54 habitable-zone planet candidates reported in February 2011, Kepler-22b is the first to be confirmed. This finding will be published in The Astrophysical Journal.

BEIJING, Jan. 6 (Xinhua) -- China will bring its nurse population to 2.86 million by 2015, meaning there will be 2.07 nurses for every 1,000 people, according to a blueprint on nursing issued Friday by the Ministry of Health (MOH).By the end of 2010, China has registered 2.05 million nurses and there were 1.52 nurses for every 1, 000 Chinese.Even by 2015, the ratio of registered nurses for 1,000 people in China is five times fewer than countries in the European Union and the United States by current standards.By 2015, the ratio of licensed doctors to nurses will climb from 1:1 to 1:1.2, according to the blueprint.China also plans to provide more training for head nurses in large hospitals and make nursing services accessible to households and communities, according to the blueprint.The five-year nursing development plan said the government will further standardize its nurse management system and deepen health care reform in public hospitals over the next few years.The total number of registered nurses reached 2.05 million in 2010, marking a 52 percent jump from 2005, according to the blueprint.

BEIJING, Jan. 10 (Xinhua) -- Chinese State Councilor Dai Bingguo on Tuesday attended a reception at the Great Hall of People in Beijing celebrating the 20th anniversary of the establishment of diplomatic ties between China and five Central Asian countries.China successively established diplomatic relations with Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan in early January of 1992.In his address, Dai said relations between China and the five nations have achieved comprehensive and significant progress since they forged diplomatic ties 20 years ago, featuring frequent high-level visits, deepened political mutual trust, mutual support on major issues of each other's concern and expanded mutually beneficial cooperation in various fields.China and the five countries have maintained close coordination within the framework of the United Nations and the Shanghai Cooperation Organization and have positively contributed to safeguarding and promoting the world's peace, stability and development, he said.Noting China and the Central Asian nations are good neighbors, good friends and good partners, Dai said, no matter how the international situation changes, China will adhere to the policy of building friendship and partnership with its neighbors and support the five nations to independently choose their development path.China will unswervingly advance traditional friendship and cooperation with the five nations and will work with them to make unremitting efforts for building a harmonious world of lasting peace and common prosperity, he said.Dai said China will take the opportunity of celebrating the 20th anniversary to increase political mutual trust, expand mutually beneficial cooperation and develop traditional friendship with the five nations, in the hope of jointly creating a bright future for their relations.Li Xiaolin, president of the Chinese People's Association for Friendship with Foreign Countries, and diplomatic envoys from the five Central Asian nations also addressed the reception.

XIAMEN, Dec. 26 (Xinhua) -- The three-decade achievements of the Xiamen Special Economic Zone have shown that China has made the right decision to set up special economic zones (SEZs), President Hu Jintao said Monday.Hu made the remarks in a congratulatory letter to a gala held Monday in southeastern Fujian province's city of Xiamen, which is celebrating the 30th founding anniversary of its special economic zone.Over the past 30 years, the Xiamen Special Economic Zone has made marked socio-economic progress, made significant changes in people's lives, and served as a pilot area for the country's reform and opening-up and socialist modernization, Hu said.The Xiamen Special Economic Zone has made a unique contribution to promoting cross-Strait economic and trade cooperation as well as culture and personnel exchanges, Hu said in the letter.Hu also urged the economic zone to further enhance the capability of independent innovation, ensure and improve people's well being, strengthen and make innovations in social management, and better serve the peaceful development of the cross-Strait relationship.He Guoqiang, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, attended and addressed the gala.In his speech, He said the economic zone should develop high-end manufacturing business and a modern service industry, while speeding up the establishment of a market-oriented technology innovation system that integrates production with scientific research.The economic zone needs to make greater efforts in energy saving and emissions reduction as well as environmental protection by greatly developing a green and recycling-based economy, according to He.He also said that the economic zone should exert itself to increase the income of rural and urban residents, especially low-income residents, and meet people's basic requirements in terms of education and culture, employment, medical services and housing."Reasonable appeals of the people should be addressed, and behavior that undermines people's interests should be resolutely rectified," He said.In addition, He expects the Xiamen Special Economic Zone to thoroughly implement the cross-Strait Economic Cooperation Framework Agreement (ECFA) and further explore and enhance cooperation in finance and logistics with Taiwan, He said.The economic zone should also strengthen the development of direct flights, customs clearance and ports in order to facilitate direct exchanges across the Taiwan Strait, according to He.He also met with representatives of Hong Kong, Macao and Taiwan residents and overseas Chinese, who attended the gala.He said people from all walks of life in Hong Kong, Macao and Taiwan have long been active in investing, financing education and alleviating poverty in Fujian.They have not only shared the opportunities that the country's reform and development have brought forth and expanded their own enterprises, but also greatly boosted the country's socio-economic progress, He said."You are witnesses, participants and beneficiaries of the reform and opening up," He said to these representatives.The Xiamen Special Economic Zone is one of the four earliest SEZs set up after China initiated the reform and opening up in 1978. In 1984, it was expanded from the initial 2.5 square kilometers to 131 square kilometers. Last year, it was extended to span the entire city.

WASHINGTON, Dec. 16 (Xinhua) -- The U.S. International Trade Commission (USITC) Friday launched a probe into certain products from China after several U.S. companies alleged their patents were infringed.The products in question include televisions and Blu-ray players produced by Haier Group of China and Vizio Inc. under Taiwan-based Amtran Technology Company and sold in the U.S. market, the USITC said.` Five U.S. technology companies filed a complaint with USITC last month, saying those products violated Section 337 of the Tariff Act of 1930 by infringing their patents.Meanwhile, they requested the USITC issue an exclusion order and a cease and desist order against those products from China.The trade panel is scheduled to set a target date for completing the investigation within 45 days after institution of the probe. If the complaint is approved, the agency will ban importation of those products.The U.S. move came at a time when protectionism is making a comeback in the United States amid sluggish economic recovery.It is widely believed that such actions would only hurt U.S.- China trade relations that are increasingly critical to global economic recovery.
