That year, scientists found that a very simple mutation in one gene could make a virus very easy to transmit. The groups also found many combinations of genes that could make the virus spread faster and cause it to be more lethal. Hualan says that health officials now know what genes to monitor to warn of a dangerous combination ready to spread throughout the world. She also says her work tells vaccine researchers what genes to target: "The important thing is that insights from such studies will benefit disease control and prevention.”

Richie had felt a mad, exhilarating kind of energy growing in the room. . . . He thought he recognized the feeling from his childhood, when he felt it every day and had come to take it merely as a matter of course. He supposed that, if he had ever thought about that deep-running aquifer of energy as a kid (he could not recall that he ever had), he would have simply dismissed it as a fact of life, something that would always be there, like the color of his eyes . . . . Well, that hadn't turned out to be true. The energy you drew on so extravagantly when you were a kid, the energy you thought would never exhaust itself—that slipped away somewhere between eighteen and twenty-four, to be replaced by something much duller . . . purpose, maybe, or goals . . . .
