Microsoft warns of browser security flaw REDMOND, Wash. (UPI) -- U.S. software giant Microsoft says a serious vulnerability in its Internet Explorer browser could allow attackers to take control of an unprotected computer. Code to exploit the bug has already been published but Microsoft said it had no evidence it was currently being used by cybercriminals, the BBC reported Thursday. The bug involves the way IE manages a computer's memory when processing Cascading Style Sheets that define the look and feel of pages on a Web site. IE's memory management can be exploited to inject malicious code into the stream of instructions a computer processes as a browser is being used, experts say. "As vulnerabilities go, this kind is the most serious as it allows remote execution of code," said Rik Ferguson, senior security analyst at Trend Micro. "This means the attacker can run programs, such as malware, directly on the victim's computer." Microsoft is "investigating" the bug and working on a permanent fix, the company said in a statement.

Robins in Scotland battle for survival EDINBURGH, Scotland (UPI) -- Robins, icons of the Christmas season, don't practice peace and goodwill with each other and often turn murderous toward their own kind, U.K. researchers say. Experts with Scottish Natural Heritage said the festive songbirds think nothing of bumping off their rivals to ensure they get their beaks on enough food to survive, The Scotsman reported Thursday. About one robin in 10 is killed by another bird of the same species as both males and females enter into vicious battles over territory and food, a wildlife expert said. "Traditional images of peaceful robins adorn our Christmas cards at this time of year, but this harmless-looking bird is actually a territorial terror," said Tom Cunningham, reserve manager at Tentsmuir National Nature Reserve. "As well as defending territory during mating, they will often fight other robins, sometimes to the death, over scarce food resources in winter." Heavy snows sweeping across Scotland have buried their usual food supplies, he said. "A lot of birds and animals are starving this winter," he said. "It's not surprising that they're fighting each other for what they can get -- it's survival of the fittest at the moment. They really are territorial creatures."

FDA approves vaccine for anal cancer WASHINGTON (UPI) -- The U.S. Food and Drug Administration says it has approved a vaccine to prevent anal cancer caused by the human papilloma virus. The vaccine Gardisil is approved for children and young adults 9 to 26 years of age, the FDA said in a release Wednesday. Gardasil, made by Merck, is already approved for the same age population for the prevention of cervical, vulvar and vaginal cancer, and the associated precancerous lesions caused by HPV in women. It is also approved for the prevention of genital warts caused by certain types of HPV in both men and women. "Treatment for anal cancer is challenging; the use of Gardasil as a method of prevention is important as it may result in fewer diagnoses and the subsequent surgery, radiation or chemotherapy that individuals need to endure," Dr. Karen Midthun, director of the FDA's Center for Biologics Evaluation and Research, said in the FDA statement. Although anal cancer is uncommon in the general population, the incidence is increasing and HPV is associated with approximately 90 percent of anal cancer, the FDA said.

Polar bear status at heart of climate war WASHINGTON (UPI) -- A U.S. decision on the species status of polar bears has environmentalists and businesses arguing over the issue of global warming, observers say. The Interior Department was in U.S. District Court in Washington Wednesday defending its decision to classify polar bears as "threatened" rather than "endangered" despite ongoing shrinkage of the bears' sea ice habitat, the Los Angeles Times reported Thursday. Several environmental groups have sued to change the bears' status to endangered, which would pressure the Obama administration to attack the sea ice problem they say is caused by greenhouse gases emitted by petroleum, coal and manufacturing companies that scientists say are a major contributor to climate change. The government's decision to retain the bears' "threatened" status comes amid industry pressure, environmentalists say. "There is a pronounced push-back from industry because they rightly see that they will have to modify or mitigate their activities to comply with the laws," said Andrew Wetzler of the Natural Resources Defense Council, one of the groups suing to change the polar bears' status. The Interior Department's "threatened" listing of the bears includes the so-called "4d" exemption, which excludes greenhouse gases from being regulated as a threat to a species. Industry groups including the American Petroleum Institute, the U.S. Chamber of Commerce and the National Mining Association are fighting to keep the exemption. "It's based upon the position that the science doesn't exist to draw a link between a particular activity, industrial or otherwise, and an identifiable incremental effect on sea ice," Richard Ranger, senior policy adviser for the API, said.
