单选题Animal studies are under way, human trial protocols are taking shape and drug makers are on alert. All the international health community needs now is a human vaccine for the bird flu pandemic sweeping a cluster of Asian countries. The race for a vaccine began after the first human case emerged in Hong Kong in 1997. Backed by the World Health Organization (WHO), three research teams in the US and UK are trying to create a seed virus for a new vaccine. Their task is formidable, but researchers remain optimistic." There are obstacles, but most of the obstacles have been treated sensibly," says Richard Webby, a virologist at St. Jude Children's Research Hospital in Memphis, Tennessee. The biggest challenge is likely to be the rapidly mutating virus. Candidate vaccines produced last year against the H5N1 virus are ineffective against this year's strain. Scientists will have to constantly monitor the changes and try to tailor the vaccine as the virus mutates. They can't wait to see which one comes next. The urgency stems from fears that I-ISN1 will combine with a human flu virus, creating a pathogen(病原体) that could be transmitted from person to person. But if people have no immunity to the virus, the strain may not mutate as rapidly in people as it does in birds. To quickly generate the vaccine, researchers are using reverse genetics, which allows them to skip the long process of searching through reassorted viruses for the correct genetic combination. Instead, scientists clone sequences for hemagglutinin(红血球凝聚素) and neuraminidase(神经氨酸苷酶), the two key proteins in the virus. The sequences are then combined with human influenza genes to create a customized reference strain. Because products developed with reverse genetics have never been tested in humans, the candidate vaccines will first have to clear regulatory review. In anticipation, the US Food and Drug Administration (FDA) and the European Agency for the Evaluation of Medicinal Products (EMEA) are both preparing pandemic response plans. The EMEA has produced a fist-track licensing program, an industry task force and detailed guidance for potential applicants. In Europe, a reassortant influenza virus -- but not the inactivated vaccine -- produced by reverse genetics would be considered a genetically modified organism, and manufacturers would need approval from their national or local safety authorities. The WHO has prepared a preliminary biosafety risk assessment of pilot-lot vaccine, which could help speed up the review. A preliminary version of their protocol calls for several hundred subjects, beginning with a group of young adults and gradually expanding to include those most susceptible to the flu -- children and the elderly." If we had product," says Lambert," it would probably be a couple of months at the earliest before we have early data in healthy adults./

单选题Halfway through" The Rebel Sell," the authors pause to make fun of" free-range" chicken. Paying over the odds to ensure that dinner was not, in a previous life, confined to tiny cages is all well and good. But" a free-range chicken is about as plausible as a sun-loving earth-worm": given a choice, chickens prefer to curl up in a nice dark corner of the barn. Only about 15% of" free-range" chickens actually use the space available to them. This is just one case in which Joseph Heath, who teaches philosophy at the University of Toronto, and Andrew Potter, a journalist and researcher based in Montreal, find fault with well-meaning but, in their view, ultimately naive consumers who hope to distance themselves from consumerism by buying their shoes from Mother Jones magazine instead of Nike. Mr Heath and Mr Potter argue that" the counterculture," in all its attempts to be subversive, has done nothing more than create new segments of the market, and thus ends up feeding the very monster of consumerism and conformity it hopes to destroy. In the process, they cover Marx, Freud, the experiments on obedience of Stanley Milgram, the films" Pleasantville"," The Matrix" and "American Beauty", 15th-century table manners, Norman Mailer, the Unabomber, real-estate prices in central Toronto (more than once), the voluntary-simplicity movement and the world's funniest joke. Why range so widely? The authors' beef is with a very small group: left-wing activists who eschew smaller, potentially useful campaigns in favor of grand statements about the hopelessness of consumer culture and the dangers of" selling out". Instead of encouraging useful activities, such as pushing for new legislation, would-be leftists are left to participate in unstructured, pointless demonstrations against" globalization, or buy fair-trade coffee and flee-range chicken, which only substitutes snobbery for activism. Two authors of books that railed against brands, Naomi Klein ("No Logo") and Alissa Quart("Branded"), come in for special derision for diagnosing the problems of consumerism but refusing to offer practical solutions. Anticipating criticism, perhaps, Messrs Heath and Potter make sure to put forth a few of their own solutions, such as the 35-hour working week and school uniforms (to keep teenagers from competing with each other to wear ever-more-expensive clothes). Increasing consumption, they argue throughout, is not imposed upon stupid workers by overbearing companies, but arises as a result of a cultural" arms race": each person buys more to keep his standard of living high relative to his neighbors'. Imposing some restrictions, such as a shorter working week, might not stop the arms race, but it would at least curb its most offensive excesses. (This assumes one finds excess consumption offensive; even the authors do not seem entirely sure.) But on the way to such modest suggestions, the authors want to criticise every aspect of the counterculture, from its disdain, for homogenisation, franchises and brands to its political offshoots. As a result, the book wanders: chapters on uniforms and on the search for" cool" could have been cut. Moreover, the authors make the mistake of assuming that the consumers they sympathise with—the ones who buy brands and live in tract houses—know enough to separate themselves from their purchases, whereas the free-trade-coffee buyers swallow the brand messages whole, as it were. Still,it would be a shame if the book' s ramblings kept it from getting read. When it focuses on explaining how the counterculture grew out of post-World War Ⅱ critiques of modem society, "The Rebel Sell" is a lively read, with enough humour to keep the more theoretical stretches of its argument interesting. At the very least, it puts its finger on a trend: there will be plenty of future critics of capitalism lining up for their free-range chicken.
