Two scientists who independently concocted potentially dangerous strains of bird flu viruses?and have had the bioweapons community in a tizzy for the past month with the pending publication of their work?today said that they would suspend their research for 60 days. The announcement is intended to be a kind of time out, a chance for everyone to catch up with the realization that influenza is no longer solely a matter of public health, but is now a potential bioweapon.
