For bees and the plants they pollinate — as well as for beekeepers, farmers, honey lovers and everyone else who appreciates this marvelous social insect — this is a catastrophe.加拿大温哥华——目前,世界各地的蜂群都在大批死亡:每年都有大约三分之一的蜂巢坍塌,这种现象已持续了10年之久。对于蜜蜂及通过它们授粉的植物——还有养蜂人、农民、喜爱蜂蜜的人,以及所有欣赏这种神奇的群居昆虫的人而言——这都是个灾难。But in the midst of crisis can come learning. Honeybee collapse has much to teach us about how humans can avoid a similar fate, brought on by the increasingly severe environmental perturbations that challenge modern society.但是,这种危机之中也隐藏着一些学问。蜂巢的坍塌可以提供许多信息,告诉我们当愈加严重的环境问题对现代社会构成挑战之时,人们如何才能避免相似的命运。Honeybee collapse has been particularly vexing because there is no one cause, but rather a thousand little cuts. The main elements include the compounding impact of pesticides applied to fields, as well as pesticides applied directly into hives to control mites; fungal, bacterial and viral pests and diseases; nutritional deficiencies caused by vast acreages of single-crop fields that lack diverse flowering plants; and, in the ed States, commercial beekeeping itself, which disrupts colonies by moving most bees around the country multiple times each year to pollinate crops.蜜蜂的死亡尤其令人忧心,因为起因并非只有一个,而是有上千种轻微的破坏因素。主要原因包括,农田喷洒的杀虫剂,以及为了抑制小虫直接喷到蜂窝上的杀虫剂所造成的综合影响;带有真菌、细菌和病毒的害虫,以及疾病;由于大面积种植同一种作物而缺乏多种开花植物所造成的营养不足;在美国,商业养蜂人每年都会多次带蜂群在全国各地为作物授粉,这种做法也对蜂群造成了破坏。The real issue, though, is not the volume of problems, but the interactions among them. Here we find a core lesson from the bees that we ignore at our peril: the concept of synergy, where one plus one equals three, or four, or more. A typical honeybee colony contains residue from more than 120 pesticides. Alone, each represents a benign dose. But together they form a toxic soup of chemicals whose interplay can substantially reduce the effectiveness of bees’ immune systems, making them more susceptible to diseases.然而,真正的问题并不在于问题的多少,而是问题间的相互作用。我们从蜂群身上得出了一则核心教训,一旦忽视,就会给我们带来危险,那就是协同作用的概念——即一加一等于三,或者四,甚至更大的数值。一般而言,每个蜂巢都含有120多种杀虫剂残余物。单独来看,每种杀虫剂的剂量都是良性的。但是如果放在一起,它们就会形成一种有毒的化学液体,这些化学物质相互作用,会极大地破坏蜜蜂的免疫系统,让蜂群更容易患病。These findings provide the most sophisticated data set available for any species about synergies among pesticides, and between pesticides and disease. The only human equivalent is research into pharmaceutical interactions, with many prescription drugs showing harmful or fatal side effects when used together, particularly in patients who aly are disease-compromised. Pesticides have medical impacts as potent as pharmaceuticals do, yet we know virtually nothing about their synergistic impacts on our health, or their interplay with human diseases.这些发现所提供的,关于杀虫剂与杀虫剂、杀虫剂与疾病之间发生协同作用的数据集,是所有物种中最为详细的。对于人类,唯一对等的是对药物相互作用的研究。许多处方药在同时使用时,都会表现出有害乃至致命的副作用,对于那些已经生病的患者来说尤其如此。杀虫剂与药物的作用一样强大,但我们其实根本不知道它们会对我们的健康产生怎样的协同作用,也不知道它们会如何与人类的疾病相互影响。Observing the tumultuous demise of honeybees should alert us that our own well-being might be similarly threatened. The honeybee is a remarkably resilient species that has thrived for 40 million years, and the widesp collapse of so many colonies presents a clear message: We must demand that our regulatory authorities require studies on how exposure to low dosages of combined chemicals may affect human health before approving compounds.我们应该从观察蜜蜂大量死亡的现象中获得警示:我们自己的健康同样可能会受到威胁。蜜蜂是一种生命力极强的物种,4000万年来,繁衍不息。大量蜂群死亡的现象向我们传达了一条明确的信息:我们必须要求监管机构做出要求,在批准混合药物之前,必须研究低剂量的混合化学物会对人类健康造成何种影响。Bees also provide some clues to how we may build a more collaborative relationship with the services that ecosystems can provide. Beyond honeybees, there are thousands of wild bee species that could offer some of the pollination service needed for agriculture. Yet feral bees — that is, bees not kept by beekeepers — also are threatened by factors similar to those afflicting honeybees: heavy pesticide use, destruction of nesting sites by overly intensive agriculture and a lack of diverse nectar and pollen sources thanks to highly effective weed killers, which decimate the unmanaged plants that bees depend on for nutrition.蜜蜂还为我们提供了一些线索,告诉我们如何能与生态系统所提供的务建立起更具合作性的关系。除蜜蜂以外,还有数千种野蜂也能提供农作物所需的授粉务。不过野生蜂——即不是养蜂人所养的蜜蜂——也受到了与蜜蜂的境况相似的威胁:大量使用杀虫剂;农耕过于集中造成筑巢区被摧毁;高效除草剂的使用,减少了花蜜和花粉来源的多样性——除草剂大量消灭了作为蜜蜂营养来源的野生植物。Recently, my laboratory at Simon Fraser University conducted a study on farms that produce canola oil that illustrated the profound value of wild bees. We discovered that crop yields, and thus profits, are maximized if considerable acreages of cropland are left uncultivated to support wild pollinators.最近,我在西蒙弗雷泽大学(Simon Fraser University)的实验室对生产菜籽油的农场进行了研究。研究发现,野蜂能发挥重要价值。我们发现,如果把相当一部分农田留出来不耕作,而是用来为野生授粉昆虫提供生存资料,那么粮食产量和收入就会最大限度地提高。A variety of wild plants means a healthier, more diverse bee population, which will then move to the planted fields next door in larger and more active numbers. Indeed, farmers who planted their entire field would earn about ,000 in profit per farm, whereas those who left a third unplanted for bees to nest and forage in would earn ,000 on a farm of similar size.野生植物种类繁多,就意味着蜜蜂也会更健康、种类更多,然后就会有更多、更活跃的蜜蜂飞到旁边的种植区。把所有农田种满的农民,每个农场的收益约为2.7万美元(约合17万元人民币),而对于那些面积相当的农场,如果留出三分之一的农田不耕作,而是供蜜蜂筑巢和搜寻食物,其收益则为6.5万美元。Such logic goes against conventional wisdom that fields and bees alike can be uniformly micromanaged. The current challenges faced by managed honeybees and wild bees remind us that we can manage too much. Excessive cultivation, chemical use and habitat destruction eventually destroy the very organisms that could be our partners.这种逻辑与常规观念存在冲突,后者认为我们可以对农田和蜜蜂等事物进行细致入微的管理。但家养的蜜蜂和野蜂目前所面临的挑战提醒却我们,我们或许管得太多了。过度的耕作、化学品的使用和栖息地的破坏,最终会破坏原本能成为我们的合作伙伴的有机体。And this insight goes beyond mere agricultural economics. There is a lesson in the decline of bees about how to respond to the most fundamental challenges facing contemporary human societies. We can best meet our own needs if we maintain a balance with nature — a balance that is as important to our health and prosperity as it is to the bees.这种观点的意义不仅在于农业经济学。蜂群数量的减少告诉我们要如何回应当代人类社会所面临的最基本挑战。如果我们能与自然保持平衡,我们就能最好地满足自己的需求——这种平衡对于我们的健康和繁荣很重要,对蜂群也一样。 /201409/326502上海较好的整容医院

上海市第一人民医院激光点痣多少钱A secret Santa brought an early Christmas gift to cash-strapped shoppers by spending ,000 paying off their outstanding bills.一个神秘的圣诞老人为囊中羞涩的人们提早送出了圣诞礼品——他用2万美元为他们买了单。Staff at Walmart were stunned when Greg Parady asked if he could contribute towards customer#39;s Christmas layaway bills.当格雷格·帕拉第询问他是否能帮购物的人们付清圣诞购物的货款时,沃尔玛的工作人员感到十分吃惊。After overhearing another shopper say she may not be able to afford her outstanding bill, Mr Parady wandered over to the layaway department to see what he could do to help.在偶然听到一个购物者说她可能没办法付掉未付账单时,帕拉第先生走进分期付款商品保留部,他想知道自己是否能帮上一点忙。After asking the manager to tally up all the outstanding balances, Mr Parady was shocked to hear that ,000 worth of gifts hadn#39;t been paid for, and saddened by how many families were struggling to put presents under their tree.帕拉第先生请经理结算了所有的未清商品余额,当他得知这些圣诞礼物总共还欠款8.9万美元时,帕拉第先生感到很震惊,却也很伤心,因为居然有这么多家庭为了圣诞树下的礼物而如此艰难。The 40-year-old made a significant dent in the debt however, after swiping a variety of personal credit cards through the machine.刷了好大一笔钱之后,这位40多岁的大善人当然也为了这次的大开销担上了债务。#39;I came back here and just saw him swiping and swiping,#39; said his businesspartner, Cindy Nazzaro, who accompanied him on the visit.“我到这儿就为了看他不停地刷卡”,和帕拉第一同前来的合伙人辛迪·纳扎罗说道。He paid the bills of six shoppers who were in the store at the time, as well as paying off half of every bill over 0.他为当时在商场的6个购物者买了单,也付了每笔超过200美元的账单的一半款项。Staff at the store recalled how the holiday hero swiped his card for customers who approached the till to cancel their orders, simply saying #39;Merry Christmas#39; afterwards.商场的工作人员回忆这位“节日英雄”为那些在收银台准备取消账单的购物者们刷卡买单的情形,每次刷完卡他就会说一句“圣诞快乐”。#39;They didn#39;t know what was happening at first,#39; said Wal-Mart operations manager Deb Davis.“一开始他们还不知道发生了什么事”,沃尔玛的运营经理德布·戴维斯说道。#39;This one girl in particular, she goes, ;What do I owe?; My associate goes, #39;That gentlemen right there just paid for you.;#39;“有个女孩子问道,‘我还欠多少?’”,我的同事说,“那位先生已经为你买好单了。”Overwhelmed, the woman, began to cry and had to sit down on a bench.这个女生感动得泣不成声,不得不坐在长凳上缓缓情绪。His spending was so unexpected, Mr Parady#39;s banks began to decline transactions in the fear his credit cards had been stolen.由于帕拉第先生的开销如此反常,他的担心他的信用卡被盗,开始拒绝处理这张卡的交易行为。The man used three different cards, took up two cashiers, and also made payments over the phone during the hours-long spree which employees described as the most generous they had ever seen.在这个长达好几个小时的狂欢购物中,帕拉第先生付款时用了3张信用卡,2台收银机,同时也通过电话进行付,工作人员表示这是他们见到过的最慷慨的行为了。#39;I didn#39;t intend for the attention but I hope it motivates other people,#39; he said.“我并不想哗众取宠,我只是想通过这种方式来鼓励大家多做善事”,他如是说。#39;I hope everyone will use it as a tool to give in their own way. It doesn#39;t have to be money, it can be time, or just something kind.#39;“我希望大家把它当做一个例子来举一反三。做好事不一定用钱,也可以是时间,或者一些好的东西。”The so-called #39;layaway Santas#39; have been popping up across the US since 2011.从2011年起,所谓的“帮你买单的圣诞老人”已经在美国各地不断出现。Walmart alone has noted 1,000 cases where a stranger has paid off another#39;s bill this year, while KMart said over .5million had been spent by well-wishers in years past.沃尔玛称今年已有1000件陌生人为购物者们买单的事情发生,同时凯马特称过去几年中“祝福者”付的账款超过了150万美元。 /201312/270371 The options for people who have no time to cook and don’t want to go out to eat every night can be disappointing. A group of entrepreneurs, including David Chang of the Momofuku restaurants, is starting a company that plans to make high-quality restaurant food that it expects to deliver in as little as 15 minutes.The secret, the group says, is technology.The partners, along with Mr. Chang, are Caleb Merkl, Akshay Navle and William Gaybrick, all of whom have experience in delivery, mobile technology and finance. Their company, called Maple, is intended to be in operation next year.Mr. Merkl said he and Mr. Navle came up with the idea out of frustration with existing food delivery systems. “Restaurants don’t focus on home delivery,” he said.With Maple, they plan to create smarter routing systems and better packaging and choices of dishes, issues that restaurants do not necessarily address when it comes to delivery. Algorithms that efficiently work out who orders what and where, and how to fulfill the orders, will be part of the system.Mr. Merkl said that Mr. Chang was enthusiastic from the beginning and that Momofuku became one of the investors. Maple’s initial funding is million.Mr. Chang is the chief culinary officer, and he will enlist the expertise of other New York chefs, along with food suppliers like farmers, to create the s. Maple’s s will change daily. A typical dish may run to , including tax, tip and delivery.Customers will place orders using an app. Food from a commissary kitchen will, according to the plans, arrive on their doorsteps fast, fresh and hot. “Our goal is 15 minutes,” Mr. Merkl said. That sounds like a pipe dream in Manhattan, where 15 minutes may get you from Midtown to 14th Street without traffic. “Our delivery area will be incredibly tight,” he said.Depending on the response from potential customers, they will decide where to locate their kitchens, which could number from 15 to 30.Consumers who are interested in using the service can sign up at trymaple.com.没时间在家烹饪又不想天天晚上出门吃饭的人可能没有多少选择。于是Momofuku餐馆的大卫·张(David Chang)等几位创业者筹划开办一家公司,提供高质量的15分钟餐馆外卖。他们说,秘密在于技术。除了张先生,其他合作伙伴还有卡勒布·默克尔(Caleb Merkl)、阿克谢·纳维尔(Akshay Navle)和威廉·盖布里克(William Gaybrick),他们有物流、移动技术和金融领域的工作经验。公司名叫“梅普尔”(Maple),计划于明年开业。默克尔说,他和纳维尔对目前的食品外卖系统感到不满,于是就想出了这个主意。“餐馆不重视家庭外卖,”他说。他们计划通过梅普尔建立更加智能的外送路线系统,以及更好的包装和更多食品选择,这些问题都是其他餐馆外卖并不需要特别考虑的。系统使用算法高效地处理顾客点了什么,送到哪里,以及如何满足订单等问题。张是公司的厨艺执行官,他将列出纽约其他厨师的专长,还有农场等食品供应商的信息,在此基础上创立菜谱。梅普尔的菜谱会每天更换。一般一道菜大概在12到15美元,含税、小费和外送费。顾客可以使用app点菜。来自相关供应厨房的食品可以根据制定好的计划,尽快到达顾客家中,并保持新鲜和温度。“我们的目标是15分钟送达,”默克尔说。这听上去有点像一个曼哈顿白日梦。要知道,没有交通堵塞的情况下,15分钟内也只能从中心城赶到14街。“我们的外送区非常严密,”他说。他们将根据潜在客户的回馈调整厨房的地址,计划开办15-30家。对此务感兴趣的客户可以登陆trymaple.com。 /201411/341755上海哪家医院激光取痣比较好上海治疗黄褐斑多少钱
