This is a much more interesting criticism, thank you for sharing it. This is out of my wheelhouse but I would be very surprised if virions were destroyed in a recently deceased and frozen body. There's not a whole lot of water in a virion, so it shouldn't be torn apart by ice. Virions decay fairly quickly since they don't have machinery to maintain themselves, but the reactions which break them down should be arrested by the cold. I've started algae cultures from frozen samples before, I can't imagine that even tough, small, spherical cyanobacteria are as resistant to frost as viruses. The headline to me is an indication that this is a hypothesis under investigation. For better or worse, a lot of science news is about ongoing research that may not pan out. I think that asks more of the reader, in terms of holding ideas lightly and checking in as the story develops, but I don't think it's a flaw per day.
