Back in Los Angeles, last-minute preparations are under way to get the dinosaurs y for the public.回到洛杉矶后,紧锣密鼓地展开了面向公众的恐龙展的最后准备。Its only now that you get a sense of just how many people have been involved in creating this exhibition, from the artists to the designers, to the teams that made the interactive media and mounts for the dinosaurs, all of it bring into life of decades of research that our current scientific understanding relies on.现在你意识到组织这场展会有多少人的参与,从演员到设计师,再到制作互动媒体和恐龙的撑架,这些都展现了我们当今科学家花几十年恐龙研究的成果。The exhibition consists of over 300 specimens. Its taken more than six years to complete and cost tens of millions of dollars.展览由300多个标本组成。花了六年的时间和数千万美元的成本。Weve created an exhibit that this part of the world has never seen.我们创建了一个从未见过的一部分世界。And its very rewarding for me to think about the millions of kids and the millions of people that during the next twenty years will visit this exhibit and will remember this exhibit for the rest of their lives.让我感到非常欣慰的是,在接下来的二十年里,会有数以百万计的孩子和成人将会参观这个展会,并且在他们的一生中留下深刻的印象。These animals look like something out of a comic book or a Hollywood studio, but they were real.这些恐龙看上去像漫画书里的或者是好莱坞工作室中的,但是它们是真实的。From a pile of dusty bones millions of years old, we can put a skeleton back together, flesh it out, tell what colour there creatures were and even say something about how they grew up.从一堆尘土飞扬有几千万年历史的骨头中,我们可以把骨骼拼凑到一起,充实肌肉,说出恐龙的颜色,甚至能说出他们是怎么生长的。I think this is a unique time to be a dinosaur paleontologist.我认为这是成为恐龙古生物学家的特别时刻。We are finding so much, discovering new dinosaurs and learning new things about them.我们找到这么多,发现新的恐龙,知道有关它的新知识。There are certainly still gaps in our knowledge, but I find it amazing just how much we do know about there extinct animals that no one has ever actually seen alive and that lived so many millions of years ago.我们掌握的知识还是有欠缺,但是我觉得我们发现了那么多有关我们从来都没有见过,已经灭绝了的恐龙的知识还是很了不起的。The creatures themselves are utterly all inspiring.恐龙本身是非常鼓舞人心的。But I think so is the incredible amount of work and vast numbers of people involved in reconstructing them so that we can come face to face with a dinosaur.但是我是这么认为的,很多重建工作的伙伴承受着难以置信的工作量,是大家的共同努力,今天才为观众们带来与恐龙面对面的展会。201302/227442Science and Technology Pesticides Smoking them out科技 农药 把它们熏死Tobacco extracts protect plants from pests and pathogens烟草提取物可用于植物病虫害THERE are, as Paracelsus put it, no poisons—only poisonous doses. That is certainly true of nicotine. The amount in a puff from a cigarette acts as a pleasant stimulus. The amount in a packet of 20, injected in one go, would kill you.巴拉赛尔士曾说:世上其实没有毒药,所谓的毒药只是有毒性罢了(更正:所谓的毒性只是剂量变化引起的而已)。对于尼古丁,这当然是确切无疑的。吸一口烟你可能会觉得神清气爽,但如果一次性把一包20的烟全下去(更正:但是如果一次性注射一包20烟的尼古丁剂量),可是会要了你的命的。The Victorians understood this and regularly used nicotine as a lethal poison—not for people (except in the minds of a few crime novelists) but for insects. The invention of modern, synthetic insecticides has more or less killed that practice off. But Cedric Briens of the University of Western Ontario is thinking of reviving it, and is also asking whether tobacco has any other pesticidal properties that might be exploited by the hard-pressed horticulturalist.维多利亚时代的人明白这一点,并且逐渐把尼古丁当做一种致命毒药来使用(更正:并且已经把尼古丁作为一种常见的致命毒药来使用)——不是用来杀人(除了在一些犯罪小说家的构思中),而是用来杀虫。而现代合成杀虫剂的发明在一定程度上结束了尼古丁的使命。现在,西安大略大学的塞德里克?布里安则又在考虑重新启用尼古丁,同时在设法验烟草是否具有一些穷困潦倒的园艺家曾苦苦追寻的杀虫效果(更正:同时在设法验烟草是否还有其他杀虫功能,期望可为饱受病虫害之苦的园艺家所利用)。To find out, Dr Briens and his colleagues at Canadas agriculture ministry ground up dried tobacco leaves using a blender and a sieve. They then heated the result in a pressurised, oxygen-free environment to distil out what they could in the form of a treacly oil. They tested this oil on 11 species of fungus and four types of bacterium that are common agricultural problems. They also tried it on the larvae of Colorado beetles, a notorious pest of potatoes.为此,布里安士和他在加拿大农业部的同事们用搅拌机和筛子将烟叶碾碎,然后将碾碎后的烟叶在高压、无氧环境下加热,提取出一种以粘稠油状存在的物质。他们用这种油对农业中常见的11种真菌和4种杆菌,以及一种常见的令人闻之生厌的马铃薯害虫——科罗拉多甲虫进行了试验。As they report in Industrial and Engineering Chemistry Research, the researchers found that several pestilential organisms were affected by the oil. Specifically they discovered that Pythium ultimum, a fungus that attacks aubergines, peppers, lettuces, tomatoes and cucumbers as seedlings, Clavibacter michiganensis, a bacterium that kills young plants and deforms fruits, and Streptomyces scabies, a second bacterium, which causes potatoes to develop revolting scabs and for which no treatment currently exists, all stopped growing in the presence of the oil. The beetle larvae, too, were killed—though that was no surprise, since the oil contained a lot of nicotine.他们的研究结果发表在《工业化学与工程化学研究》上。研究报告显示这种油对好几种有害的有机生物有作用。研究明确地发现,在这种油的作用下,危害幼苗期茄子、青椒、莴苣、番茄、黄瓜的真菌——腐霉病菌,可使幼苗致死、果实畸形的杆菌——马铃薯环腐病菌,以及另一种导致马铃薯烂痂病,且目前没有有效防治方法的杆菌——疥链霉菌,均被抑制生长。此外,甲虫幼虫也可被杀死——这其实是意料之中的,因为这种油里含有大量的尼古丁。What was a surprise was that removing this nicotine did not diminish the oils effectiveness against bacteria and fungi, and made it only marginally less effective against beetle larvae. The crude oil killed all of the larvae whereas the nicotine-free stuff left a fifth of them alive after two days. Clearly, there are other pesticides at work, and finding what they are is the next task. Meanwhile tobacco has proved itself a more useful substance than even the Victorians realised. Can its rehabilitation be far off?但意料之外的是,将这种油去除后,对细菌和真菌的影响作用却并没有降低,只是对甲虫幼虫的作用在一定程度上减轻了。布满这种油的环境中,所有的甲虫幼虫都被杀死,散乱分布的情况下,两天后也只有五分之一存活。显然,其它具有杀虫作用的物质在起作用,下一步任务就是找出这些物质。这些发现明了烟草不止可以用来做香烟,它甚至具有比维多利亚时代的发现更大的作用。如此,烟草的这种;复兴;还会远吗? /201301/222706

-Its wake-up call, saying, not only for the next two years but for the next five and ten years. It is going to be historic. It is gonna immediately occur. It is gonna be desirable. So lets do something about it, OK? Lets get those measures, those structural measures in place so that we can improve outlook so that we can have a better story and we have a better narrative, better positions that are going forward.-可以说,世界经济已经敲起了警钟,不仅是为对于未来两年,而是为未来5年或10年,这将成为历史性事件。这将很快发生,这将不可避免。因此,现在将讨论这个话题。让我们采取那些适宜的结构性措施,这样可能改善状况,从而有一个更好的结果,于是我们将来将处于更有利的位置。-They finally talked the decisions on Greece. Decisions that you knew they were always going to have to take, which was the cut, the debt burden. The only question is what took them so long.-他们最终谈到了关于希腊的决议。你知道他们将不得不实施的决定,即缩减债务负担。唯一的问题在于到底是什么让他们花费这么长时间来做决定?-Well, this has not been for the last few months. Weve been pushing for these for the last three years, Then you eventually atop for the first time last year that was not enough. And of course now because of law roads overall, you are having a Greece struggle so. But whats more important is you took integrate of you. You are asking efforts from the Greeks. Yes, but you’re giving a little bit more time in order to get their goals. And you’re giving lower interest rates, longer periods to repay the public debts and you have decided to go in by bank the private debt at a bigger discount. It’s time it’s uninteresting but. You’ve also giving them back the profits from the Central Bank. -噢,可不只仅仅是过去几个月,我们在过去的三年都在推行,因此说截止去年才首度开始是不准确的。因为一体化道路,目前是苦苦挣扎的希腊。更重要的是,你要采取整合策略。你要希腊做出更多努力,延长他们达到预期目标的时间,同时,给予希腊低利率,更长的公债偿还期,还决定由插手低价购回私人债务。这是一段乏味、漫长的时间,但是你还是要从央行向他们返还利润。-Im just posing you that because if they are dealing with Greece, its time to deal with Spain.-我这样问你,是因为他们目前正在解决希腊危机,现在是时候处理西班牙问题了。-No way. Absolutely nothing to do. Heres two different things. Spain has done its homework. Spain has much half the debt of Greece, OK, in terms of GDP. And Spain has five years of surpluses in their budgets before the crisis struck. So what Spain needs is unequivocal message from the Europeans and IMF to the market saying. If Spain decided to request support, because theyve done their homework, because they are performing, because they are viable economy, then they will be supported. And that request will be enough to detonate the ECB to go and buy their bonds in secondary market if need to be.-目前没有采取办法,没有任何补救措施。这是两种完全不同的情况。西班牙已做足自己的功课。西班牙的债务数量是希腊的一半,但是对于GDP来说,在危机爆发前,西班牙连续5年预算盈余。因此, 西班牙需要只是欧盟和IMF的明确信息:如果他们已经做足功课,因为执行效果不佳,因为经济的可变性,西班牙若决定要求持,那么将会给予他们持。他们的要求足以促使欧洲央行在需要的情况下,在二手市场购买他们的债券。 201212/214751

(We call it) by the name Supervan, the transit van was one of the greatest stalwarts of the industry, the self-starred backbone of a working economy. With the European economy on its knees, even the mighty Ford has struggled to stand up right, in the end something has to give. Its South Hampton part, the home of the transit will be closed.货车,也被大篷车,曾是汽车工业最为中坚的力量之一,一个重要经济产业的柱。由于欧洲经济低迷不振,福特巨人也不得不挣扎着求得生存,最后还是得有所放弃,即将关闭福特英格兰南安普顿货车工厂。I wanted to carry on for a few more years, I mean, here is the news, for the young people its bad news.我曾想再坚持几年,但是现在的事实是关闭工厂,对年轻人来说,这是个坏消息。What must be very frustrating for the people who work here is that the problem with sales or a lack of sales lies not in the UK but in Continental Europe. And its not a reflection of Fords product, which is still held in quite high regard, it is just a fact that in the current age, people cannot afford to buy a new car or a new van. It is supposed the financial equivalent of ;Its not you. Its me.;这里工作的人一定非常沮丧。但是销售存在问题或者说滞销,这一问题不仅存在于英国,而且存在于整个欧洲大路。这并不是说福特产品不好,实际上福特产品仍然在公众心目保有很高的认可地位。只是目前的这个历史阶段,人们买不起新轿车或新货车。等同于金融上的,“错不在你,在我”。The official announcement in respect of the UK and wide businesses will be made on Thursday. But the Belgian factory in Genk found out its fate first. It too will close down.福特将于周四做出关于英国及其他业务的官方申明。但是比利时亨克工厂已经第一个知道自己将被关闭的命运了。I hope the people who are responsible for all this will sleep well tonight. So many families will end up on the street.我希望负责此事的人今晚能够睡个好觉,毕竟有那么多家庭将露宿街头。Fords plant in Belgium employs 4,300 people. But unions warn the job losses will be closer to 10,000. In the UK, Ford employs around 15,000 workers overall plus thousands more in the supply chain. Its been predicted that losses in Europe will climb to more than 1 billion dollars later this year.福特在比利时的工厂的员工近4300人。不过工会的预告是失业的人数将接近1万人。福特在英国的员工总数大约在1.5万人,还要再加上1千多人在供应环节的员工。根据预测,今年下半年欧洲的损失额将攀升至超过10亿美元。Speaking at Sky News last month, even the companys chief executive couldnt put a gloss on the reality.公司董事长上个月在天空新闻台的讲话也没有粉饰残酷的现实。Were clearly in the downturn when it comes to the economy. So youve watched us continually reduce our production and the resources to go with that to match the, our production to the real demands.我们的经济确实处于低谷。大家可以看到我们不断减产减少消耗,以此使生产与实际需求匹配。The Southampton plant is only a small part of Fords European operations, but this expected closure signals a general decline in the industry. Peugeot, Volkswagen and others are also struggling.英格兰南安普顿货车工厂仅是福特在欧洲众多工厂中一家,但是这一预期的闭厂预示了汽车工业的总体下滑趋势。标致、大众以及其他汽车制造商都在苦苦挣扎中。We will be impacted by, you know, the European situation. But we have a degree of resilience or protection if you like. Because we are selling products to fast-growing markets, places like China, Russia, the US and Middle East. And that obviously helps to balance off the you go significant declines we are seeing in mainland Europe.我们将继续受到欧债危机的影响。但是我们保持了一定的弹性或者着自保能力。因为我们在向那些快速增长的市场出售产品,如中国、俄国、美国以及中东。这显然有助于平衡我们在欧洲大陆所遭遇的显著下降。Interestingly, Fords plans to cut capacity is a sign that the company believes things wont get better for a few years yet. By cutting jobs in order to cut losses, they are making their move before their rivals. It will be no surprise though, if others go down the same road.有意思的是,福特减产却在表明,福特并不相信几年内情况会变糟糕。裁员是为了减少损失,他们在对手之前抢先行动了。因此,如果其他汽车制造商也采取此类作法,也就毫不奇怪了。201211/210177
