CANBERRA, Dec. 9 (Xinhua) -- Scientists from Australia's University of New England on Friday said they had discovered the remarkably fossil isa metre-long arthropod with excellent vision called anomalocaris from Emu Bay Shale of South Australia.The scientists reported their finding on the anomalocaris in thescience journal Nature this week.It is reported that anomalocaris is a fearsome ancient predator that swam in the Cambrian oceans 500 million years ago. The researchers said the presence of anomalocaris would have driven the development of protective adaptations in prey animals. Such an escalatory 'arms race' would have seen, for instance, the evolution of such adaptations in prey as shells, camouflage and burrowing into sediments. "It has been unbelievably frustrating being able to see eyes like these at fossil sites like the Burgess Shale (in the Canadian Rocky Mountains), but not have any details. It is really refreshing to have our ideas about these animals confirmed at last, " comments Simon Conway Morris, a palaeontologist at the University of Cambridge, the United Kingdom.The research team was led by paleontologist Dr John Paterson, of the University of New England. He said the most surprising discovery of anomalocaris is the huge number of tiny hardened lenses in each eyes."When you consider that a modern housefly, for example, has about 3000 lenses, it's pretty impressive that an animal half a billion years old already has remarkable vision like this," Paterson said in statement."The fact that each eye in anomalocaris would have had over 16, 000 lenses means it would have very, very good resolution."Paterson said the acute vision of Anomalocaris gave it a distinct advantage over competing predators and prey, as many Cambrian animals either had poor vision or were completely blind. Its acute vision rivals or exceeds that of most living insects and was probably comparable to predatory dragonflies today.He said their findings support the idea that compound eyes evolved very early on in arthropod evolution, before the evolution of jointed legs or hardened exoskeletons.The research team hopes they can find the more fossil remains of Cambrian creatures in the Emu Bay Shale.

BEIJING, Oct. 8 (Xinhua) -- Authorities hope to innovate social management by restructuring its governmental organ, an official said in an interview with Xinhua and the People's Daily on Saturday.The organ, the Central Committee for Comprehensive Social Management, was renamed and restructured in a meeting last month from the previous Central Committee for Comprehensive Management of Public Security.With 11 more departments than the previous one, the new committee, with 51 departments, is expected to strengthen and innovate social management so as to build a harmonious, stable society, an official from the general office of the committee said.The official said the renaming and restructuring of the committee came as the former's concepts, mechanisms and measures fell behind China's fast social and economic development after its 20 years of existence.The official said the new committee will primarily address some major issues that could threaten social harmony and stability, such as criminal gangs and juvenile delinquency, while enacting laws and regulations for social management.

BEIJING, Dec. 24 (Xinhua) -- Renowned China economist Li Yining said Saturday that adjusting the structure of China's economy is a "matter of life and death" while the structure of GDP is more important than its size.The focus of the country's economic structure adjustment now should be transforming the dual structure in the urban and rural economy, which causes the widening income gaps between urban and rural residents, Li said at the China Economic Forum.He also noted that the key to stimulating domestic demand is to raise the workers' wages.With the external demand waned, the Chinese government has attempted to turn to domestic consumers to take up the slack. The country vows to expand domestic demand next year and increase residents' income, especially for disadvantaged groups.However, Li said raising household income is not enough and the government also needs to improve its social security system as well as increase construction of affordable houses and public rental houses.The country plans to begin construction or renovation on at least 7 million housing units for low-income groups next year, Minister of Housing and Urban-Rural Development Jiang Weixin said Friday.

BEIJING, Nov. 27 (Xinhua) -- China's industrial enterprises saw their profits increase 25.3 percent year-on-year in the first ten months of 2011, slowing down from the year's previously recorded figures, official data showed Sunday.Growth in the January-October period was 1.7 percentage points lower from that of the first three quarters, the National Bureau of Statistics (NBS) said in a statement.It marked a gradual downshift from the 34.3-percent year-on-year growth seen during the January-February period and the 28.7-percent growth seen during the first half of the year.Profits realized in the first ten months amounted to 4.12 trillion yuan (650 billion U.S. dollars), the NBS said.The NBS compiled the figures using data collected from a pool of industrial businesses with at least 20 million yuan in annual sales revenues each.In October alone, industrial profits expanded 12.5 percent year-on-year to 438.3 billion yuan, the NBS said.Among 39 industries surveyed, 36 sectors reported profit growth in the first ten months. The oil refining, coking and nuclear-fuel processing sector saw profit plunge 89.8 percent year-on-year.Private businesses posted the fastest profit growth, with a year-on-year rise of 44.3 percent, followed by collectively owned enterprises of 33 percent, equity-holding companies of 30.3 percent, state-owned enterprises of 16.6 percent and overseas-funded firms of 11.6 percent.China's industrial production growth rate will moderate due to economic turmoil in Europe and the United States and weakening domestic demand brought about by a tightened monetary policy, Huang Libin, an official with the Ministry of Industry and Information Technology, said last week.China saw its economic growth slow to 9.1 percent in the third quarter of this year from 9.5 percent in the second quarter and 9.7 percent in the first quarter.
