Some people suffer the nuisance of seasonal hay fever, snuffling and sneezing as p
26、ollen flows through the air. Others react to materials such as metals, developing unpleasant rashes at their very touch. And some sorry souls go into shock at the mere presence of certain foods, particularly peanuts and shellfish.The cause in each case is an oversensitive immune system that is react
27、ing to harmless materials as well as to the pathogens it is supposed to be fighting. This creates annoying and sometimes life-threatening symptoms. Chronically over-reactive immune systems may not, though, be an entirely bad thing. Another role played by the immune system is to destroy malignant tum
28、ours before they take holdand work carried out recently by Annette Wigertz of the Karolinska Institute, in Stockholm, and her colleagues suggests that the immune systems of those with allergies may be particularly good at this. However, in a nice example of the way that one set of data is sometimes
29、capable of divergentindeed, oppositeinterpretations, she may instead have discovered a clue about how cancers shut down immune systems in order that they themselves may prosper.This Manichean finding came after Dr. Wigertz and her team interviewed 1,527 people with gliomas (a type of brain turnout)
30、in Denmark, Finland, Norway, Sweden and the south-east of England. The researchers asked the patients in question whether they had a history of allergies, and then compared the results with those for 3,309 otherwise similar individuals who did not have brain tumours. As Dr. Wigertz reports in the Am
31、erican Journal of Epidemiology, the tumour-free were, indeed, more likely to suffer from allergies. The presence of an allergy was associated with a 30% reduction in the likelihood of having a glioma.This was not all that surprising. Previous research had detected similar inverse correlations betwee
32、n allergies and brain tumours, suggesting that a welcome side effect of allergy was resistance to cancer. But this new study went further. It looked carefully at the time in the patients lives when their allergies were active, and it found that this timing was crucial. Dr. Wigertz noted that the abs
33、ence of allergy was correlated with the time when a glioma first formed. That was true even in people who had previously had allergies which had then cleared up.Awkwardly, this result is open to two rather different interpretations. The optimistic explanation is that the hyperactive immune system as
34、sociated with allergy does, indeed, protect against turnouts. In that case, the coincidence was caused by turnouts taking advantage, as it were, of the reduced immune surveillance that accompanied the disappearance of the allergy. The sinister interpretation is that tumours are doing something as th
35、ey grow that suppresses the immune system and thus allergic reactions. Either way, turnout and lack of allergy coincide. And either way, something interesting is going on. But Dr. Wigertzs result illustrates the perils of leaping to conclusions on the basis of incomplete data.（分数：5.00）(1).Which of t

40、nsequence of their study.BText 2/BThe award of the Nobel science prizes often brings blinking into the limelight people who have laboured unknown to the wider world. Seldom, though, is there such a compelling human story to go with the intellectual one as that of Mario Capecchi, one of the winners o
41、f the medicine prize. His father was an airman who was killed in North Africa during the Second World War. His mother was sent to Dachau concentration camp. He survived more than three years as a street kid in Italy before migrating to America after the war was overand yet he ended up helping to dev
42、elop one of the most important tools of modern biology, the knockout mouse.It is not quite a rags-to-riches story. In truth, his family was well connected in a bohemian sort of way, and his mother (the daughter of a painter and an archaeologist) was an American. But it does make great copy for repor
43、ters covering an event that has the true characteristics of celebrity. For, like many of those who populate the pages of celebrity magazines, the Nobel prizewinners are most famous for being famous. In most years, the prize-winning work itself makes dull copy.This year, however, the prize committees
44、 of the Karolinska Institute (Swedens main medical school) and the countrys Royal Academy of Science seem to have taken some lessons in public relations. Not only have they picked a researcher with an interesting back-story, but they have also cunningly disguised a deserved but possibly contentious
45、award by bundling it in with something else. On top of that, one of the topics chosen for a prize has an obvious resonance with the public.The bundling was done in the medicine prize. Dr Capecchi shares this with Oliver Smithies, another immigrant to America (he was born in Britain) and Sir Martin E
46、vans, a Briton who stayed at home. Working independently, these three men provided the parts that, when put together, enable the elimination of one gene at a time from the genetic make-up of a mouse. That is of medical significance because it allows mouse “models“ of human genetic diseases to be mad

It is for giant magnetoresistancethe basis of modern computer hard-drive memories. The phenomenon itself was discovered, independently, by Albert Fert, a Frenchman, and Peter Grunberg, a German, in 1988. Its significance is that a small magnetic field can induce a large change in
