Marshall and J. Robin Warren toppled

2、 the conventional wisdom in more ways than one. They proved that most ulcers were caused by a lowly bacterium, which was an outrageous idea at the time. But they also showed that if science is to advance, scientists need the freedom and the funding to let their imaginations roam.Lets start with the

3、Nobel pairs gut instincts. In the late 1970s, the accepted medical theory was that ulcers were caused by stress, smoking, and alcohol. But when pathologist Warren cranked up his microscope to a higher-than-usual magnification, he was surprised to find S-shaped bacteria in specimens taken from patien

4、ts with gastritis. By 1982, Marshall, only 30 years old and still in training at Australias Royal Perth Hospital, and Warren, the more seasoned physician to whom he was assigned, were convinced that the bacteria were living brazenly in a sterile, acidic zonethe stomachthat medical texts had declared

5、 uninhabitable.Marshall and Warrens attempts to culture the bacteria repeatedly failed. But then they caught a lucky breaker rather, outbreak. Drug-resistant staph was sweeping through the hospital. Preoccupied with the infections, lab techs left Marshalls and Warrens petri dishes to languish in a d

6、ark, humid incubator over the long Easter holiday. Those five days were enough time to grow a crop of strange, translucent microbes.Marshall later demonstrated that ulcer-afflicted patients harbored the same strain of bacteria. In 1983, he began successfully treating these sufferers with antibiotics

7、 and bismuth (the active ingredient in Pepto-Bismol). That same year, at an infectious disease conference in Belgium, a questioner in the audience asked Marshall if he thought bacteria caused at least some stomach ulcers. Marshall shot back that he believed bacteria caused all stomach ulcers.Those w

8、ere fighting words. The young physician from Perth was telling the fields academically pedigreed experts that they had it all wrong. “It was impossible to displace the dogma,“ Marshall explained to me in a jaunty, wide-ranging conversation several years ago. “Their agenda was to shut me up and get m

9、e out of gastroenterology and into general practice in the outback.“At first, Marshall couldnt produce the crowning scientific proof of his claim: inducing ulcers in animals by feeding them the bacterium. So in 1984, as he later reported in the Medical Journal of Australia. “a 32-year-old man, a lig

10、ht smoker and social drinker who had no known gastrointestinal disease or family history of peptic ulceration“a superb test subject, in other words“ swallowed the growth from a flourishing three-day culture of the isolate.“The volunteer was Marshall himself, Five days later, and for seven mornings i

11、n a row, he experienced the classic and unpretty symptoms of severe gastritis.Helicobacter pylori have since been blamed not only for the seething inflammation ,of ulcers but also for virtually all stomach cancer. Marshalls antibiotic treatment has replaced surgery as standard care. And the wise guy

12、 booed off the stage at scientific meetings has just won the Nobel Prize.What does all this have to do with scientific freedom? Today, US government funding favors “hypothesis-driven“ rather than “hypothesis-generating“ research. In the former, a scientist starts with a safe supposition and conducts

13、 the experiment to prove or disprove the idea. “If you want to get research funding; you better make sure that youve got the experiment half done,“ Marshall told me. “You have to prove it works before theyll fund you to test it out.“By contrast, in hypothesis-generating research, the scientist inche

14、s forward by hunch, gathering clues and speculating on their meaning. The payoff is never clear. With todays crimped science budgets and intense competition for grants, such risky research rarely gets funded. Proceeding on intuition, Mar- shall told me, “is a luxury that not many researchers have.“I

15、t helps, he added, to be an outsider. “The people who have got a stake in the old technology arc never the ones to embrace the new technology. Its always someone a bit on the periphery-who hasnt got anything to gain by the status quowho is interested in changing it.“（分数：70.00）(1).This weeks Nobel Pr

It is uncultured, selfish,

41、meaner than the meanest act of any lesser animal. For although in order to secure a mate or food or to flee danger, a beast will sometimes stop at nothing in trying to get ahead of the next fellow creature, it at least does it openly, guiltlessly, without the sophistication peculiar only to man.One

42、of the more usual procedures of queue-jumping involves finding an acquaintance in the queue, going up to him, starting a conversation, perhaps offering him a cigarette, and finally squeezing ones way into the line.Even if one does not know a single person in the line, one is not put out. One goes up

43、 and down the queue, studying the faces, deciding on a susceptible one, stopping by its side, moving on as the queue moves on and, at the most opportune moment and without a by-your-leave, plants oneself just ahead of it. If the owner of the face does not protest, as happens more often than you imag

44、ine, the thing is done. On one of the occasions on which I was chosen as the owner of such a face, the queue-jumper even had the cheek to ask: “Wasnt I standing here a moment ago?“Speaking of cheek, I must relate what I overheard a well-dressed middle-aged lady, herself a queue- jumper, remark to an

45、 associate of hers: “Just look at those domestic servants. They are always jumping the queue. Theres no stopping them. “Has ever a beast or bird been known to “out-cheek“ her?（分数：40.00）(1).In order to gain profits, a beast will sometimes _.（分数：8.00）A.help his fellow creatures to share with himB.try
