WASHINGTON, Dec. 2 (Xinhua) -- The U.S. Justice Department Friday approved Google's 400 million dollar acquisition of Admeld, a company that provides an online advertising platform for publishers.The Justice Department concluded that it was "not likely to substantially lessen competition in the sale of display advertising."Google operates the largest Internet search engine in the world and one of the largest display advertising platforms. It had revenues of about 29 billion dollars in 2010, most of which came from ads revenue.Admeld, with annual revenue of 30 million dollars, offers technology services to Internet publishers that help them boost revenue by optimizing ads display from hundreds of sources.Google is expected to grab 9.3 percent of online display advertising spending in the U.S. this year, up from 8.6 percent last year, making it the No. 3 provider, according to the digital intelligence company Emarketer.The No. 1 position will be taken by Facebook with its share increased to 16 percent up from 12 percent a year ago, while Yahoo! will slip slightly to 13 percent, said Emarketer.

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.

WELLINGTON, Oct. 26 (Xinhua) -- New Zealand's geothermal scientists will be collaborating with the world's leading geothermal researchers after the country joins an elite international group next month.New Zealand would be admitted to the International Partnership for Geothermal Technology (IPGT) in Melbourne, Australia, on Nov. 16, Science and Innovation Minister Wayne Mapp announced Wednesday."Geothermal energy is one of our most important renewable energy resources with huge potential for growth," said Mapp."This recognition of our geothermal research programs will allow our scientists to collaborate with an elite group of researchers in the United States, Australia, Switzerland and Iceland."Scientists from New Zealand research organizations were committed to finding new ways to harness the country's extensive geothermal fields, said Mapp."Innovation and clean energy is a big part of enabling New Zealand to grow the economy," said Mapp."This new international partnership will help keep us at the forefront of technology developments such as enhanced geothermal systems."Established in 2008, the IPGT seeks to develop advanced, cost- effective geothermal energy technologies through international research co-operation.New Zealand's geothermal electricity generation rose by 21 percent last year and accounted for 13 percent of total electricity generation, its highest recorded level.The government is aiming to expand geothermal energy with three large geothermal projects in the pipeline by 2020.The country's biggest geothermal project is to be Contact Energy's 250-megawatt Tauhara II geothermal project.The project, being developed northeast of the central North Island town of Taupo, is expected to produce enough electricity to meet the needs of around 270,000 homes when it becomes fully operational in 2015.
