In this Thursday, April 26, 2012 file photo, Balinese government officials prepare to cull chickens as a precautionary measure to prevent the spread of bird flu, at a market in Denpasar, Bali, Indonesia after an 8-year-old boy died from bird flu. The virus rarely infects people, but scientists are worried it could mutate and spread more easily. On Wednesday, May 2, 2012, a scientific journal published a study showing how scientists created their own lab-made bird flu virus. The experiment was an effort to figure out how to thwart a global epidemic. (AP Photo/Firdia Lisnawati)

A homeless man begs for money near paintings from a street artist in the Plaza Mayor, in Madrid, Monday, April 30, 2012. Spain's National Statistics Institute announce on Monday that Spain is officially back in recession as the country's economy shrank 0.3 percent in the first quarter compared to the previous three months. This is Spain's second recession in three years. Spain's economic problems have become the focus of Europe's debt crisis as investors worry over Spain's ability to push through austerity measures and reforms at a time of recession and an unemployment rate hitting 24 per cent - or 50 per cent for those aged under 25. Late last week, S&P downgraded the country's credit rating by two notches from A to BBB+, citing a worsening budget deficit, worries over the banking system, and poor economic prospects.

A protesters stands outside the Portalnd City Club during the attorney general candidate's debate with Dwight Holton and Ellen Rosenblum Friday, April 27, 2012, in Portland, Ore. Medical marijuana could be a deciding issue in Oregon's attorney general race. Former federal prosecutor Dwight Holton has been critical of the state's medical marijuana law. And his opponent, retired state Court of Appeals Justice Ellen Rosenblum, has emerged as a staunch supporter _ even showing up at a Portland pot shop to show support. There are 55,000 registered medical marijuana users in Oregon _ and who knows how many smoke weed illegally. It's an open question whether they'll vote. Still, there's wide support among Oregonians for using marijuana as medicine, and Rosenblum might be able to capitalize on that in the May 15 Democratic primary. (AP Photo/Rick Bowmer)
