In science, the unwritten rule has always been to publish your results first and worry about the fallout later. More knowledge is always good, right? Information wants to be free.
But what if the thing you want to publish is truly frightening? Millions dead kind of frightening.
This isn't a rhetorical question, in light of some experiments now in the pipeline for publication. H5N1 influenza viruses—a.k.a Avian flu—are efficient killers that have wiped out some poultry flocks and a few hundred hapless people who were in close contact with the birds. (New Scientist reports that 565 people are known to have caught the bird flu and 331 died.)
