He had entitled the story Adventure, and it was the apotheosis of adventure—not of the adventure of the storybooks, but of real adventure, the savage taskmaster, awful of punishment and awful of reward, faithless and whimsical, demanding terrible patience and heartbreaking days and nights of toil, offering the blazing sunlight glory or dark death at the end of thirst and famine or of the long drag and monstrous delirium of rotting fever, through blood and sweat and stinging insects leading up by long chains of petty and ignoble contacts to royal culminations and lordly achievements.

They discovered that airborne transmission was associated with a single genetic change in the engineered virus’s hemagglutinin that gave it the ability to bind to mammalian-type α2,6 SA of a particular class (long chain) without the loss of the other introduced changes that had made it a α2,3 SA binding type.

CPTI exchanges carnitine for the CoA attached to long chain fatty acids to form a fatty acid-carnitine conjugate (RCO-carnitine).
