These are people who, it was discovered, are carrying around extra taste buds on their tongues, making the world of eating much more intense.你可能也听过有这样一个群体——品尝师。他们是被挖掘出的特殊人群,他们的舌周围广泛分布着味蕾,让吃东西变得异常有“感觉”。Its not at all an unusual thing: the latest data suggest that one out of every four people is a supertaster. For them, eating is a much richer, more flavorful experience than for the rest of us.这并不稀奇:最新数据显示每四个人中就有一个人是品尝师。相比于我们这些普通人,他们吃东西时会有更丰富、更美味的体验。Still, before you get too jealous if youre not a supertaster, it turns out there are drawbacks to having a technicolor tongue. A study that looks specifically at supertasters over the age of sixty-five found that they have more colon polyps than folks who arent so taste bud gifted.然而,你也不用因为自己无法成为超级品尝师而对他们羡慕不已。事实明,拥有那样“华丽丽”的舌头也会带来某些不好的影响。专门对65岁以上的品尝师展开的一项调查研究发现,他们比那些未被赋予“超常”味蕾的人们患结肠息肉的概率更高。Colon polyps are the things you want to have removed before they become cancerous, which is why all folks fifty and older should get a yearly colon exam.结肠息肉容易发生癌变,因而它是“人人得而诛之”,这也是为什么人们上了50岁每年都得进行一次肠息肉检查。Why do supertasters have more colon polyps? It isnt known. But supertasters also weigh more on average than non-supertasters, and weight increases cancer risk. The reason for this may be as simple as it sounds: eating is more fun when you taste in 3-D.为什么品尝师们容易患上结肠息肉?具体原因还待考。但有一点,品尝师们的体重一般都比普通人重,而体重会增加患癌症的风险。而他们体重偏重的原因就跟大家听起来一样:多方位的品尝食品时,饮食让人倍感无穷乐趣。Some researchers think, however, that the problem may not just be an increase in pleasure. Those extra taste buds may also drive people away from food thats good for them, such as vegetables, because the taste of, say, a brussels sprout is just too intense.然而,很多研究人员又认为原因很可能不仅仅是在饮食当中增加了乐趣。这些多出来的味蕾会让品尝师们对一些有益身体健康的食物(如蔬菜)敬而远之。这是因为这些食物(蔬菜)的滋味,比如说抱子甘蓝,就太重了。 /201209/202199连云港治疗慢性软下疳需要多少钱

Such leeway would make it easier for a female cuckoo to lay where she chose.这样的空当就给了雌杜鹃自由选择巢穴产卵的机会。Nick Davies and Justin Welbergen, a pair of ornithologists at Cambridge University, have now corrected that omission.尼克·戴维斯贾斯汀·韦伯尔根是剑桥大学的鸟类学专家,它们现在补充了这种遗漏。They have tested the idea that cuckoos mimic hawks—or, at least, that warblers think cuckoos look hawklike.它们已经实了杜鹃会模仿鹰—或者说,至少在莺看来,杜鹃非常像鹰。As they report in the latest edition of Behavioral Ecology, they have found that it is true, but only up to a point.就像它们在最新一期的Behavioral Ecology上报道的那样,它们已经发现这是正确的,但至少在某种程度上可以这么讲。To carry out their test, Dr Davies and Dr Welbergen put stuffed birds near reed-warbler nests,为了进行它们的测试,戴维斯士和韦伯尔根士将几种鸟类标本放到了莺的芦苇巢附近,to observe the nestholders reactions.用来观察这些巢主人的反应。They used three species: sparrowhawks, cuckoos.他们用了三种鸟类:雀鹰,杜鹃,还有鸽子。The breast of each stuffed bird was adorned with a piece of white silk.每种鸟类的胸前都用一块白色的丝绸装饰。Some pieces of silk were left plain.一些丝绸偏左放置。Others had bars drawn on them with a felt-tip pen.其它条纹则用记号笔画制而成。Once the stuffed birds were in place, the two researchers recorded the reactions of the nestholders.一旦将这些鸟类标本放置好,这两位研究人员就记录巢主人的反应。In particular, they measured how closely the nestholders were willing to approach the stuffed intruder,他们会专门评估这些巢主人对于不速之客的接近程度,and also how noisily the intruder was mobbed, in an attempt to drive it away.以及围攻入侵者并试图将其赶走的激烈场景。The barring, they found, was crucial.他们发现了一个非常关键的例外。Though the warblers could clearly tell the difference between the species,虽然莺类可以很清楚地分辨出这些鸟类的不同,in the cases of all three types of stuffed bird those decorated with stripes were approached more cautiously and mobbed less than those without stripes.对于那些装饰了条纹的三种鸟类标本,它们更谨慎地接触,并且围攻那些没有条纹的鸟类。Hawk-like stripes do, then, provoke what is, from a cuckoos point of view, the desired reaction:从杜鹃的角度来看,鹰状条纹所起的主要作用就是它所希望看到的:less of the sort of behaviour that is likely to interfere with her egg-laying mission.如果缺乏这种行为会则会影响到杜鹃的产卵任务。Not perfect mimicry, but good enough to be useful.虽然这种模仿不甚高明,但已经足够用了。Probably, Dr Davies and Dr Welbergen have caught cuckoo and warbler in the middle of an evolutionary arms race.也许戴维斯士和韦伯尔根士已经注意到了杜鹃和莺正处于一个进化的军备竞赛中。Come back in 10,000 years and cuckoos and sparrowhawks may be indistinguishable.回到10000年前,杜鹃和雀鹰或许就难以分辨了。 点击此处下载本期经济学人讲解PDF与音频字幕 /201304/233256 Over 18,500 participants in 1,202 teams joined the 26th annual mass swim across Sun Moon Lake in Nantou County in central Taiwan.来自1,202个队的超过18,500名游泳者参加了在台湾中部南投县举行的第26届大众游泳横渡日月潭的活动。The swimmers also included 246 people from Australia, Great Britain, China, Hong Kong, Holland, Japan, Singapore and the ed States, and 297 physically challenged participants, the organizers said.主办单位说,其中包括246名来自澳大利亚、英国、中国、香港、荷兰、日本、新加坡和美国的游泳者,另外还有297名残障人士。The event kicked off at 7 a.m., and it took most of the participants 90 to 120 minutes to complete the approximately 3,000-meter swim. The Nantou County Government said that in view of the two deaths that occurred last year, they took special precautions this year. Measures included deploying 20 top-notch diving professionals and equipping them with propulsion equipment and underwater GPS systems for the first 100 meters, known to be the most dangerous stretch.活动在上午7时拉开序幕。大多数游泳者花了90至120分钟才完成了大约3000米的泳程。南投县政府表示,鉴于去年发生的两人死亡事件,他们今年采取了特别的预防措施。措施包括:部署了20个顶尖的潜水专业人员,这些人员装备了推进设备;前100米还安装了水下GPS系统——因为前100米往往是最危险的阶段。The event was also moved up to the end of August, instead of in mid-September or later when it was usually held, in consideration of colder water temperatures later in the year. This year, an electronic board was erected at the starting point to show the temperature of the water for the reference of the swimmers.考虑到水温会逐渐变冷,活动将持续到八月底,而不是以往的9月中旬。今年,在出发点竖立了一个电子模板以显示水的温度。The organizers also introduced a color-coded system this year so that the lifeguards could easily identify different groups of people. Physically challenged swimmers and those over 65 years of age were required to wear pink swimming caps, while other participants were asked to wear red ones.主办单位还推出了色编码系统,这可以使今年的救生员很容易地识别不同的人群。残障人士和超过65岁的人都必须戴上粉红色的泳帽,而其他游泳者则被要求带上红色泳帽。注:本文译文属原创,,。201204/179592连云港包皮手术需多少钱东海县有治疗前列腺炎吗
