After half a year of stormy debate, we are finally getting to see all the gory details about how two teams of scientists produced some disturbing flu viruses. I’ve written about this unfolding story previously here, at Slate, here again, in the New York Times, and back here again.

In tomorrow’s New York Times, I step back and take a look at the two published studies, and talk to experts about what those studies do–and don’t–tell us about how likely we are to face a new flu pandemic in the years to come. There’s still a huge amount about the flu that we don’t know yet, sorry to say. Check it out. (I also spoke with Times editor Michael Mason on this week’s science podcast. Listen here.)
