Last month the World Health Organization's external committee on smallpox recommended that the two scientific teams possessing smallpox virus be allowed to insert a green fluorescent marker gene into the virus to test the efficacy of potential antismallpox drugs. The WHO committee had actually made at least seven recommendations (see The Scientist Daily News, November 19, for all of them). It tried to keep the complete recommendations under wraps, even after someone leaked the fluorescent marker recommendation to National Public Radio.
