U. S. Says Details of Flu Experiments Should Stay Secret

"A committee that advises the government says that details of two controversial experiments on bird flu virus should not be made public, because of fears that the work could provide a recipe for a bioweapon."

"The government-funded experiments were done by researchers who wanted to understand if bird flu virus might change in the future to cause a pandemic in people. By tweaking genes, they made the deadly bird flu virus more contagious between lab animals."

"In a landmark decision, an expert panel known as the National Science Advisory Board for Biosecurity, which advises the government, says key details of the work should not be published openly."
