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.

SAN FRANCISCO, Nov. 4 (Xinhua) -- With its popular iPhone series, Apple seized more than half of the profits generated by the top eight mobile phone manufacturers during the third quarter, said a monthly market analysis released on Friday.Apple generated a remarkable 52 percent of handset industry operating profits for the top eight OEMs (original equipment manufacturers) in the third quarter, up five percent over the same period of 2010, said Canaccord Genuity technology analyst Michael Walkley.The number was down from 57 percent in the second quarter, due to a drop in iPhone sales as customers held out for the upcoming iPhone 4S.A proud Apple customer shows off the new iPhone 4S he purchased at an Apple store in Munich, Germany.Apple's major rival in the mobile industry is Samsung. The two companies together represented 81 percent of the handset industry' s operating profits last quarter.Other major mobile phone manufacturers are Nokia, Motorola, Sony Ericsson, HTC, Research In Motion and LG.Calling it "an epic reversal of fortunes," Walkley noted that in 2007, Nokia had 67 percent of operating profits while Apple had just 4 percent. Compared with Apple's 52 percent of industry profits in the third quarter of 2011, Nokia has been relegated to its rival's former position with just 4 percent of operating profits.The analyst said he has conducted "channel checks" that show strong demand not only for the new iPhone 4S but also for the previous models of iPhone 4 and iPhone 3GS. He told technology news website AllthingsD that Apple is believed to be able to gain further value share in the December quarter and capture over 60 percent of industry profits.In a Bloomberg report on Friday, several technology analysts said the two-year-old iPhone 3GS, whose price has been slashed to zero if it is purchased with a contract, will become one of Apple' s big weapons in the coming holiday season against smartphones running Google's Android system.

BEIJING, Nov. 27 (Xinhua) -- A government official on Sunday refuted an accusation that discriminations widely exist in the country's civil service recruitment process.Nie Shengkui, director of the examination and recruitment department of the State Administration of Civil Service (SACS), said that the recruitment process is always based on the principles of justice and fairness, which has promoted the upward mobility of people from the grassroots.The ratio of recruited male and female applicants is around 6 to 4 in last year, equal to the ratio of the male and female applicants, and more than 92 percent of the recruited are from the ordinary families in the grassroots, including 29 percent from the rural areas, according to Nie.Nie's words came after a survey report published earlier last week, accusing the authorities of having discriminatory requirements in civil servants recruitment.Conducted by the Constitutionalism Research Institute of China University of Political Science and Law, the survey report said that without publicly acknowledging any form of discrimination, many public offices don't hesitate to hide their preferences on age, gender, education and state of health in recruitment.Nie defended that it is necessary to set some requirements in the recruitment in a bid to guarantee the future civil servants can carry out there duty competently."Civil servants recruitment is a process of choosing talents for the government to manage the country, not for promoting employment," said Nie, "so there is nothing to do with employment discriminations."Chinese college grads are usually enthusiast about finding jobs within government branches, especially at a time when people are trying to secure a stable future amid a troubled global economy.A total of 970,000 applicants took the general exam of the recruitment on Saturday and Sunday, They will compete for only 18,000 posts in central government departments and their local branches.

NANCHANG, Oct. 1 (Xinhua) -- A copper sword dating back more than 2,200 years has been discovered in east China's Jiangxi Province, local archaeologists said.The design and shape of the sword indicate that it was forged during the Warring States Period (475 BC - 221 BC), according to Li Guoli, curator of the Nanchang Museum, where the sword is currently being stored.Despite having little aesthetic or scientific value due to a lack of decor or inscriptions, the sword still offers insights into the type of military equipment used during the period, Li said.The identity of the sword's original owner and the precise location where the sword was forged and used are still unknown, Li said.The sword was discovered by a laborer surnamed Xiong in Jiangxi's capital of Nanchang. Xiong found the sword while sorting and cleaning stones that had been dredged up from a riverbank.An argument between Xiong and another worker who was trying to claim the sword aroused attention from the local law enforcement, who then convinced Xiong to turn the sword over to archaeological authorities.

UNITED NATIONS, Nov. 21 (Xinhua) -- Dramatic progress in science, political leadership, and results indicate that 2011 was a "game changing" year for the international AIDS response, and much progress has been made in 2011 to check AIDS-related deaths since 1997, the peak of the epidemic, a new report released by the Joint United Nations Program on HIV/AIDS (UNAIDS) said on Monday."The Report on the Global AIDS Epidemic 2011" found that new infections were reduced by 21 percent since 1997, and deaths from AIDS-related illnesses decreased by 21 percent since 2005, according to the report.Furthermore, 47 percent (6.6 million) of the estimated 14.2 million people eligible for antiretroviral therapy treatment in low- and middle-income countries were accessing treatment, in increase of 1.35 million people since 2009.The report also found early signs that HIV treatment is having an impact on reducing the number of new HIV infections. As treatment reduces the viral load of a person living HIV to almost undetectable levels, it also reduces the risk of transmitting the virus to an uninfected partner, according to the report. Studies also show that treatment can be up to 96 percent effective in preventing HIV transmission among couples.Eleven countries, including many Sub-Saharan African countries, reached "close to universal access" for AIDS treatment, which is determined to be 80 percent access, in 2011.Botswana made the most dramatic progress in scaling up access to treatment, the report said. While sexual patterns remained relatively stable in the country since 2000, access to treatment increased from less than 5 percent in 2000 to more than 80 percent in 2011.Despite progress, however, the report does note that 2011 marks an unprecedented high the number of people infected with HIV worldwide.Globally, an estimated 34 million people are currently living with the infection. Approximately 2.7 million got infected with the virus in 2010, and as many as 1.8 million people died of AIDS- related illnesses in 2010.Yet the report also notes estimates that as many as 2.5 million deaths are estimated to have been averted in low- and middle- income countries due to increased access to HIV treatment since 1995."Now is not the time to reduce our efforts despite some good news on reducing new infections. Infections are decreasing, but not rapidly enough," said Kim Nichols, executive director of African Services Committee, on Monday at a press conference."There are fewer AIDS deaths, but with the number of infections increasing, prevention has to be the mainstay of our response," Nichols said.Indeed, the UNAIDS report calls for a new framework for investments which are focused on "high-impact, evidence-based, high-value strategies," according to a press release from the UNAIDS website.The framework, which aims to achieve universal access to treatment and prevention centers by 2015, requires a 22-24 billion US dollar funding increase by 2015.Given the withering state of the global economy -- donor funding for the AIDS response has dropped from 7.6 billion in 2009 to 6.9 billion in 2010 -- raising that kind of money may be a long shot. Regardless, UNAIDS'new investment plan calls for smarter uses of less money.According to the report, the framework will focus on high-risk populations like sex workers, men who have sex with men, and people who inject drugs and prevent infections among children, as well as invest in behavior change programs, condom promotion, and treatment, care and support for people living with HIV."The world faces a clear choice: maintain current efforts and make incremental progress, or invest smartly and achieve rapid success in the AIDS response," says the UNAIDS report.
