HELSINKI, Nov.23 (Xinhua) -- Nokia Siemens Networks is planning to cut its workforce by 17,000 worldwide by the end of 2013, the company said in a statement on Wednesday in Espoo, Finland.The company said the measures are part of an extensive global restructuring program, in which it will focus on mobile broadband and services."We need to take the necessary steps to maintain long term competitiveness and improve profitability in a challenging telecommunications market," said the company's Chief Executive Rajeev Suri in the statement.Rajeev Suri called the job cuts regrettable but necessary, and said the company would provide support for individuals and communities affected by the cuts, but defended the decision on economic grounds.Nokia Siemens is aiming to cut operating expenditures by around a billion euros over two years.Some 74,000 people currently work for the Espoo-based company in 150 countries, around 7,000 in Finland. The company will announce the geographical distribution of the job cuts later on.

SAN FRANCISCO, Nov. 29 (Xinhua) -- Hewlett-Packard (HP) on Tuesday issued a statement to refute some security flaw claims on its LaserJet printers."Today there has been sensational and inaccurate reporting regarding a potential security vulnerability with some HP LaserJet printers. No customer has reported unauthorized access. Speculation regarding potential for devices to catch fire due to a firmware change is false," HP said in the statement.Tech blog "The Red Tape Chronicle" reported earlier Tuesday that researchers from Columbia University found that a feature named "remote firmware update" on HP's Internet-connected LaserJet printers could allow hackers take control of the device by installing malicious software, and even manage the printer to catch fire.In the statement, HP said that its LaserJet printers have a hardware element called "thermal breaker" that is designed to prevent a part of the device from overheating or causing a fire, noting that it cannot be overcome by a firmware change as it was reported.The Palo Alto, California-based company said that the specific vulnerability exists for some HP LaserJet printers it placed on a public Internet without a firewall. It conceded that on Apple's Mac computers and PCs running Linux system, it is possible for a specially formatted corrupt print job to trigger a firmware upgrade.The company said that it is building a firmware upgrade to mitigate the issue and suggested consumers could place printers behind a firewall and disable remote firmware upload on exposed printers.Researchers said in the earlier report that they believed the flaw is not limited to HP printers and millions of printers around the world could be vulnerable to hack attacks.

BEIJING, Oct. 18 (Xinhuanet) -- Autism can likely develop when low birth weight babies are combined with other factors such as environment and genetic predisposition, new research suggests.Researchers from the University of Pennsylvania School of Nursing and School of Medicine identified 1,105 children who weighed less than 2,000 grams at birth between Oct. 1, 1984, and July 3, 1989.Sixteen years later, researchers were able to reach 623 of those children, and used a questionnaire to screen them for autism spectrum disorders.When 189 of the children turned 21 years old, 60 percent of those who screened positive for an autism spectrum disorder, and 24 percent of those who screened negative with the condition. All in all, the rate of autism spectrum disorders among the study participants with low birth weights was five times higher than the general.Autism spectrum disorder makes people have difficulty communicating, difficulty interacting in social situations, and restrictive or repetitive interests, said study co-author Jennifer Pinto-Martin, a researcher in the University.Those with mild autism spectrum disorders, "may only want to talk about one subject," Pinto-Martin said. "They're perfectly functional. They can go to college. They can hold a job." Premature babies are often born with low birth weights, though full-term babies can also have the condition. The research suggests a need not only for better prenatal care to reduce the number of premature babies, but also a need for early diagnosis and intervention for people with autism.

WASHINGTON, Nov. 24 (Xinhua) -- A new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies.Authors of the study, which was funded by the National Science Foundation and published online on Thursday in the journal Science, say that global warming is real and that increases in atmospheric CO2 will have multiple serious impacts. However, the most Draconian projections of temperature increases from the doubling of CO2 are unlikely."Many previous climate sensitivity studies have looked at the past only from 1850 through today, and not fully integrated paleoclimate date, especially on a global scale," said Andreas Schmittner, an Oregon State University researcher and lead author on the Science article. "When you reconstruct sea and land surface temperatures from the peak of the last Ice Age 21,000 years ago -- which is referred to as the Last Glacial Maximum -- and compare it with climate model simulations of that period, you get a much different picture.""If these paleoclimatic constraints apply to the future, as predicted by our model, the results imply less probability of extreme climatic change than previously thought," Schmittner added.Scientists have struggled for years trying to quantify "climate sensitivity" -- which is how the Earth will respond to projected increases of atmospheric carbon dioxide. The 2007 IPCC report estimated that the air near the surface of the Earth would warm on average by two to 4.5 degrees (Celsius) with a doubling of atmospheric CO2 from preindustrial standards. The mean, or " expected value" increase in the IPCC estimates was 3.0 degrees; most climate model studies use the doubling of CO2 as a basic index.The researchers based their study on ice age land and ocean surface temperature obtained by examining ices cores, bore holes, seafloor sediments and other factors. When they first looked at the paleoclimatic data, the researchers only found very small differences in ocean temperatures then compared to now."Our study implies that we still have time to prevent that from happening, if we make a concerted effort to change course soon," said Schmittner.

ADDIS ABABA, Dec. 1 (Xinhua) -- Marking the World AIDS Day on Thursday at the African Union (AU) headquarters in Addis Ababa, Ethiopia, Jean Ping, the AU Commission chairperson, said Africa should no longer see new generations with HIV infection.Through his representative, Ping called upon individual and collective action to contain mother to child transmission of HIV."We should act individually and collectively not only to prevent mother to child transmission but also to take care of the health of people living with the virus," said the chairperson.He also expressed commitment of the AU Commission to work with member states and pertinent bodies in the efforts made to HIV treatment and prevention.The World AIDS Day is commemorated this year under the theme "Zero Mother to Child Transmission", as world leaders who were gathered in New York for the 2011 United Nations (UN) High Level Meeting on AIDS in June, launched a Global Plan for significant strides towards eliminating new HIV infection among children by 2015 and keeping their mothers alive.Remarkable progress has been made so far, which is proof to realize the vision of zero new HIV infection, zero discrimination, and zero AIDS-related death (the three zeros), said UN Secretary General Ban Ki-moon in the message on the commemoration of the World AIDS Day.The secretary general revealed that the number of new infections has fallen by more than 20 percent since 1997, and new infections are continuing to decline in most parts of the world.In sub-Saharan Africa, the region most affected by the AIDS epidemic, HIV incidence has decreased in 22 countries, he said.According to UNAIDS, Ethiopia, Nigeria, South Africa, Zambia, and Zimbabwe are among the African countries where new HIV infections dropped significantly."Treatment has averted 2.5 million AIDS-related deaths since 1985. Last year alone, 700,000 lives were saved. Some 6.6 million people, nearly half those who need treatment in low and middle- income countries, are now receiving it," said Ban."Synergies between prevention and treatment are speeding up progress. But, to end AIDS, we need to deliver even greater results," said the secretary general.The UNAIDS says to get to the three zeros there must be acceleration on smart investments, capitalizing on scientific advancements and respecting human rights.Speaking at the AU headquarters on the commemoration of AIDS Day, Jan Beagle, deputy executive director of UNAIDS, underlined on the need to invest smartly to achieve the vision of the three zeros.There is a global target of 22 million U. S. dollars to 24 billion dollars to fund the AIDS response, which the UNAIDS says is a shared responsibility of all countries, donors and others."International assistance for the AIDS response has declined from 8.7 billion dollars in 2009 to 7.6 billion in 2010," said the Deputy Executive Director."We need to use new technology more effectively to reduce costs and demonstrate that we can deliver return on investment," she said.The AIDS movement is a movement for inclusiveness, equity and social justice, she said, adding that it has demonstrated global solidarity is possible to address multi-sectoral challenges.According to Abdoulie Janneh, executive secretary of the UN Economic Commission for Africa (ECA), an estimated 7,000 people get infected with HIV infections every day.The executive secretary highlighted ingenious and novel approaches in introducing new HIV/AIDS prevention strategies."A combination of the traditional initiatives and innovative initiatives can all be used to eliminate new HIV infections," said Janneh.
