"Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets." After an extensive, months-long debate, one of two controversial papers showing ways the H5N1 "avian" influenza virus could potentially become transmissible in mammals with only 3 or 4 mutations was published in Nature today. The journal included an editorial on the merits and drawbacks of "publishing risky research" with regard to biosafety. The debate included an unprecedented recommendation by The US National Science Advisory Board for Biosecurity (NSABB) to block publication -- a decision they later reversed. (Via: 1, 2) Nature's special report has additional articles, including interviews with the teams behind both papers.
