It is restlessness, anxiety, dissatisfaction, agony of mind that nourish science. Jacques Monod, 1910-1977, New Scientist, 1976. Monod is someone to listen to. He and his colleagues gave us the first model explaining how a gene can turn on when it is needed and off when it is not. And so, although I don't need a lot of pushing in the direction of questioning ideas, I do think it is of value to be skeptical, especially when someone gives us an unequivocal answer as to the cause of a complex process like Post-Polio Syndrome.
Viruses are tricky creatures.
We don't understand everything about them. Until recently we didn't even know how polio got inside the cells it infects. But we are learning new things all the time. And yet, there are aspects of its life cycle which remain puzzling. To find this answer calculations must be made by a student with some knowledge of introductory college chemistry.
