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, Jan. 9 (Xinhua) -- China's official website for booking train tickets received a daily average of more than 1 billion hits during the first week of January, according to a railway official.Hu Yadong, vice minister of railways, said Sunday that the online ticket sales platform has provided consumers with a convenient way to buy tickets. He also addressed complaints about the fairness of the sales process."Train tickets sold online or by telephone have topped 2 million daily, meaning that around one-third of passengers don't have to wait in line at train stations for several hours to get a ticket," Hu said.However, many Chinese have expressed dissatisfaction with the website, with some people unable to get train tickets home for this year's Spring Festival holiday, a major holiday in China.Several customers posted their complaints on popular microblogging website weibo.com, stating that the booking site often failed due to "too many visits at the same time."The Spring Festival holiday is always a difficult time for China's public transportation authorities. A total of 3.16 billion passenger trips are expected during the holiday, up 9.1 percent from a year earlier, of which 235 million trips will be made via the country's railways, up 6.1 percent year-on-year, said Hu.This year's transport rush in the Spring Festival Season started on Sunday and will end on Feb. 16, according to the Ministry of Railways.

WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.
