BEIJING, May 20 (Xinhuanet) -- Scientists have discovered a Jupiter-sized exoplanet that is completely unbound from a host star, according the scientific journal "Nature" published Thursday.The research was conducted by astrophysicists from Osaka University in Japan.Using the technique called "gravitational microlensing", scientists turned their telescopes towards the centre of the Milky Way and detected this "lonely planet" moving in a extremely large orbit, which suggested it does not connect to any solar system.Then they estimated the total number of such wondering planets could be as many as 400 billion, based on the detection efficiency. This number far outnumbers the main-sequence stars such as our Sun."This is an amazing result, and if it is right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut.And scientist began to consider the possibility that liquid water could exist on this kind of unbound planets. "That might be an attractive possibility for life," said David Stevenson, a planetary scientist at the California Institute of Technology.

SAN FRANCISCO, May 3 (Xinhua) -- Apple Inc. announced on Tuesday that it has updated its iMac all-in-one desktop, adding Intel's next generation quad-core processors, Thunderbolt data ports and a new HD camera.Starting at 1,199 U.S. dollars, the new iMac is up to 70 percent faster and its new graphics deliver up to three times the performance of the previous generation, Apple said in a statement.The new iMac features quad-core Intel Core i5 processors with an upgrade option to Core i7 processors.The 21.5-inch model has a single Thunderbolt port while the 27- inch has two, in addition to four USB 2.0 inputs and a FireWire 800 port.Thunderbolt, which debuted with Apple's updated MacBook Pro notebooks in February, is also an Intel design bringing together high-speed data transfer and high-definition display onto a single cable. It can transfer a full-length HD movie in less than 30 seconds with a speed of 10 gigabits per second, which is twice the speed of USB 3.0, 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0.The new iMac also includes a built-in FaceTime HD camera, which supports high-definition video calls, Apple said.

BEIJING, Jan. 24 (Xinhua) -- China's top economic planner said Monday that price supervision and control measures have achieved steady progress with 2010's Consumer Price Index, slightly exceeding the target ceiling by 0.3 percentage points to hit 3.3 percent.To rein in soaring commodities prices, joint efforts have been made to manage inflation expectations, promote production, ensure supplies and strengthen price supervision in 2010, said the National Development and Reform Commission (NDRC) in an online statement.Prices of necessities accelerating during the second half of 2010 have been contained with vegetable prices down 9.4 percent in December from the previous month last year, it said.Further, prices of edible vegetable, pork, egg, sugar,liquefied petroleum gas and clothing also decreased significantly in December month on month, the statement said.To cope with rising prices beginning in July 2010, especially prices of basic supplies, the central government promptly introduced joint inter-ministerial meetings to discuss price controls among 17 ministries and ordered local governments to establish the same mechanism, it noted.Local governments have worked on improving agricultural facilities, especially in south China's Hainan province, to increase vegetables supplies for northern cities over the past year, the statement said.The statement forecasts that vegetable planting areas in 2010's autumn and winter will increase 530,000 hectares year on year, sending output to 337 million tonnes.To ensure production and supply, departments have worked to reduce fertilizer exports and promote links between production areas and purchasing areas, it added.Further, relevant authorities also took measures to stabilize prices of electricity and coal, and to ensure smooth transportation of agricultural produce.Authorities also granted temporary subsidies and raised basic wages and minimum living subsidies for urban and rural residents to guarantee people's daily life.

BEIJING, March 10 (Xinhuanet) -- Cigarette displays in shops will be banned and tobacco companies may also be forced to make their products in plain wrappers in an attempt to stop people from smoking, announced the UK government Thursday.The prominent displays and attractive packaging of tobacco have long provided shopkeepers with stable income, keeping addicts hooked and quitters tempted.However, the government's move that will begin as early as spring next year will keep cigarettes hidden away and make it just a tad more difficult for smokers to find their fix."Nearly all adult smokers started smoking before they turned 18 and every year, over 300,000 children under 16 try smoking," said Chief Medical Officer Sally Davies."Smoking is undeniably one of the biggest and most stubborn challenges in public health. Over eight million people in England still smoke and it causes more than 80,000 deaths each year," Health Secretary Andrew Lansley said in his statement on the new law.Now, this move has drawn predictable responses from both sides of the tobacco wars, with health groups cheering and retailers grumbling.The British Medical Association said it was "very pleased" with the announcement, citing research which it said showed that a display ban would play "a key role in discouraging children from smoking and also help smokers quit."On the other hand, industry groups and independent retailers complained it would burden them with the cost of refitting their stores and reduce their already narrow profit margins.And according to media interviews, many people kept skeptical about the real impact the move would have, especially on young smokers.

BEIJING, Feb. 5 (Xinhua) -- Lending to China's small and medium-sized enterprises (SMEs) rose faster than loans to large enterprises last year, according to the People's Bank of China (PBOC), the central bank.Outstanding loans to small enterprises by banks and financial institutions jumped 29.3 percent year on year to 7.55 trillion yuan (1.15 trillion U.S. dollars) in 2010, while loans to medium-sized enterprises stood at 10.13 trillion yuan, up 17.8 percent, said the PBOC.Outstanding loans to large enterprises rose 13.3 percent to 13.42 trillion yuan, highlighting the government's efforts to optimize the loan structure, the PBOC said.About 99 percent of Chinese enterprises are SMEs which contribute 60 percent of the country's gross domestic product.Financing has long been difficult for Chinese SMEs as banks prefer to lend to big companies, particularly reputable state-owned enterprises.The government has moved to help SMEs get finance by differentiating the reserve requirement ratio for the Rural Credit Cooperative, the major lender to SMEs, and encouraging innovation in SME bond issuance.In July last year, the PBOC asked financial institutions to establish independent criteria for approving loans to SMEs and to improve efficiency in processing SME loan applications.The PBOC said SME loan growth would continue to accelerate this year.
