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.

WASHINGTON, Oct. 3 (Xinhua) -- Researchers at St. Michael's Hospital in Canada have discovered a new function for an enzyme that may protect against organ injury and death from anemia, according to a study appearing Monday in the U.S. journal of the Proceeding of the National Academy of Sciences.Researchers found that when people have anemia, neuronal nitric oxide synthase (nNOS) -- an enzyme in nerve cells that produces nitric oxide, an important signaling molecule in the body -- increases the body's ability to respond, adapt to low oxygen levels and makes the body more efficient in delivering oxygen to tissues. They also found that levels of nNOS in the brain increased in anemic mice, and that the mice without this enzyme die earlier, and with higher hemoglobin levels."Identifying this mechanism may lead to new therapies and approaches to improving outcomes for anemic patients," said Dr. Greg Hare, a researcher at the Li Ka Shing Knowledge Institute of the hospital and one of the lead investigators of the study.Anemia occurs when blood has a lower than normal number of red blood cells or hemoglobin -- an iron-rich protein that carries oxygen from the lungs and heart to the rest of the body. Cells need oxygen to survive and to produce energy for all bodily functions. The condition has many different causes including infection (malaria, HIV, parasites), nutritional deficiencies (iron, folate, B12), genetic mutations, pregnancy, trauma and surgical blood loss."This research will help us identify when an anemic patient is at greatest risk for injury and death when undergoing surgery," said Hare. "Research is underway to test these findings in humans."

BEIJING, Dec. 31 (Xinhua) -- In a New Year's address broadcast on Saturday, Chinese President Hu Jintao vowed that China will continue to develop friendly exchanges with other countries and positively participate in international cooperation on global issues.While addressing domestic and overseas audiences via state TV and radio broadcasters, Hu urged the acceleration of the transformation of the country's economic development pattern and structural adjustments while making more efforts in ensuring people's livelihood.The country will continue to balance maintaining steady and relatively fast economic growth with adjusting its economic structures and managing inflation expectations, he said in the speech titled "Jointly Improve World Peace and Development," which was broadcast by China Radio International, China National Radio and China Central Television.A photo released on Dec. 31, 2011 shows Chinese President Hu Jintao delivering a New Year address, titled "Jointly Improve World Peace and Development", to domestic and overseas audiences via state TV and radio broadcasters.China will stick to the guidelines of "one country, two systems," "Hong Kong people governing Hong Kong," "Macao people governing Macao," and a high degree of autonomy in maintaining the long-term prosperity and stability of Hong Kong and Macao, Hu said."We will adhere to the principles of 'peaceful reunification' and 'one country, two systems,' continue to push forward the peaceful development of cross-Strait relations, ensure the basic benefits for those of the Chinese nationality, and endlessly work for the common benefit of the compatriots on both sides of the Taiwan Strait," he said.2011 was the first year of the country's 12th Five-Year Plan period (2011-2015). In the face of complicated international situations and arduous tasks in maintaining domestic reform, development and stability, Chinese people united and continued to push forward the opening up and reform drive and the socialist modernization construction, while maintaining steady and relatively fast economic growth and making progress in building a well-off society in an all-around way, he said.China was also actively engaged in international cooperation to boost the growth of the global economy and financial stability, and it was involved in resolving international and regional issues, he said.The world is currently witnessing multipolarization and globalization, and various countries are increasingly interdependent, Hu said."However, the instability and uncertainty of the world economic recovery is on the rise, international and regional hot-topic issues have cropped up one after another, and the peace and development of the world faces unprecedented opportunities and challenges," Hu said.China will stick to peace, development and cooperation, adhere to independent foreign policy, maintain world peace and promote common development, Hu said.The country will stick to the principle of mutual benefit when opening itself up, he said."We will develop friendly cooperations with all countries on the basis of the five principles of peaceful co-existence, and we will continue to actively participate in international cooperation on global issues," Hu said."I believe that as long as people from all countries make efforts hand-in-hand, the world will have a better future and the welfare of the people of all countries will improve," Hu said.An article by Hu on boosting the country's cultural development will be published in Qiu Shi (Seeking Truth), an official magazine of the Communist Party of China Central Committee, on Jan. 1.

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.
