Study: Obese friends not the best to have CAMBRIDGE, Mass. (UPI) -- Gaining weight may be socially contagious and the more obese friends you have the more likely you are to become obese, a study suggests. Health experts say about a third of Americans are obese and at risk of developing type 2 diabetes, heart disease and many types of cancer, USA Today reported. Harvard scientists studying the obesity epidemic have applied an infectious-disease mathematical model to data from recent obesity studies. "We find that having four obese friends doubled people's chance of becoming obese compared to people with no obese friends," researcher Alison Hill, the study's lead author, says. The more obese people you come in contact with, the greater the chance of your becoming obese, Harvard researcher David Rand says. Researchers say they aren't sure why this is so, but it may be that if you have many acquaintances with unhealthy eating habits, you wind up with similar eating habits, Rand says. Other lifestyle factors such as diet and physical activity have a huge impact on weight, Rand says, but the lesson of this research is "it's in your best interest to help your friends lose weight."

Myanmar subject of cyberattack NAYPYIDAW, Myanmar (UPI) -- Myanmar was effectively knocked off the Internet by a massive cyberattack that disrupted most network traffic in and out of the country, security experts said. A distributed denial-of-service attack over the last several days hit the country's main Internet service provider, the Ministry of Post and Telecommunication, an Arbor Networks security blog reported. The attack has been ongoing since Oct. 25, the Myanmar Times reported. The motivation of the attack was unknown. Some suspect the Myanmar government itself may be responsible, pre-emptively cutting off Internet connectivity ahead of the Nov. 7 general election. The government reportedly severed all Myanmar Internet connectivity in 2007 in a crackdown over growing political unrest. While DDoS attacks against e-commerce and commercial sites are common, large-scale politically motivated attacks remain rare, the Arbor blog said. Copyright 2010 by United Press International

NASA spacecraft in comet rendezvous PASADENA, Calif. (UPI) -- NASA's EPOXI spacecraft flew past it target, comet Hartley 2, Thursday morning and has begun returning images of the cosmic snowball, the space agency said. Scientists and mission controllers were busy viewing never-before-seen images of Hartley 2's comet nucleus on their computer terminal screens, a NASA release said. "The mission team and scientists have worked hard for this day," said Tim Larson, EPOXI project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "It's good to see Hartley 2 up close." Eight minutes after closest approach, estimated at 435 miles, the spacecraft's high-gain antenna was pointed at Earth. About 20 minutes later, the first images of the encounter made the 23 million-mile trip from the spacecraft to NASA's Deep Space Network antennas in Goldstone, Calif. "We are all holding our breath to see what discoveries await us in the observations near closest approach," said EPOXI principal investigator Michael A'Hearn of the University of Maryland, College Park. EPOXI's flyby marks the fifth time a spacecraft has visited a comet nucleus, NASA said. Copyright 2010 by United Press International

EU to stop export of nuclear waste BRUSSELS (UPI) -- New EU proposals for member states to bury their nuclear waste deep underground also would forbid its overseas export, officials said. EU Energy Commissioner Guenther Oettinger defended the draft plan announced Wednesday as a necessary measure to enforce International Atomic Energy Agency safety standards. "If an accident happens in one country, it can have devastating effects also in others," he said in Brussels. Fourteen EU member states currently operate nuclear power plants. The proposal could pose a problem for some EU countries that lack the suitable geological substrate for underground burial, EUobserver reported. Oettinger said he was confident EU member states would adopt the plan even though similar legislation has been rejected in the past. "Today the acceptance is much higher than in the past," he said. "We don't want to export nuclear waste to third countries, frequently with lower safety standards. That cheap solution is out of the question." Russia is one country that stands to lose if the new requirements are approved, as it currently does a lucrative business in importing nuclear waste for burial in Siberia. A number of African countries have expressed an interest in developing similar schemes, EUobserver said. Copyright 2010 by United Press International
