The second of two bird flu studies once considered too risky to publish was released Thursday, June 21, 2012 ending a saga that pitted concerns about terrorism against fears of a deadly global epidemic. Both papers describe how researchers created virus strains that could potentially be transmitted through the air from person to person. Scientists said the results could help them spot dangerous virus strains in nature. (AP Photo/Irwin Fedriansyah)
