惠东县人民男科医院治疗性功能障碍多少钱惠州市中心医院治疗前列腺炎多少钱Hoping to give new meaning to the term ;natural light,; a small group of biotechnology hobbyists and entrepreneurs has started a project to develop plants that glow, potentially leading the way for trees that can replace electric streetlamps and potted flowers luminous enough to by.为了给“自然光”这个词增添新意,一个生物技术爱好者和创业者小组开展了一项发光植物的研究,在此基础上也许可以研发出取代路灯的树和能供阅读用的照明盆栽花卉。The project, which will use a sophisticated form of genetic engineering called synthetic biology, is attracting attention not only for its audacious goal, but for how it is being carried out.这项研究将利用基因工程的一种高级形式——合成生物学,而它之所以受到关注,不只是因为目标大胆,还因为它的实施方式。Rather than being the work of a corporation or an academic laboratory, it will be done by a small group of hobbyist scientists in one of the growing number of communal laboratories springing up around the nation as biotechnology becomes cheap enough to give rise to a do-it-yourself movement.这项研究不是由一个企业或者是一家学术实验室来完成,它将由一个科学家兴趣小组在一家公共实验室内完成,生物技术的成本已经足够的低廉,令人们自己动手成为可能,公共实验室在全国不断涌现。The project is also being financed in a D.I.Y. sort of way: It has attracted more than 0,000 in pledges from about 4,500 donors in about two weeks on the Web site Kickstarter.这项研究的融资也正通过一种DIY的方式进行:两周时间左右它便在Kickstarter网上吸引到约4500个出资人,承诺投资超过25万美元(约合153.53万元人民币)的资金。The effort is not the first of its kind. A university group created a glowing tobacco plant a few years ago by implanting genes from a marine bacterium that emits light. But the light was so dim that it could be perceived only if one observed the plant for at least five minutes in a dark room.这种研究并非首例。几年前一个大学社团曾通过将一种发光的海洋细菌注入植物体内而研制出了会发光的烟草植株。但是由于它发出的光线太微弱,只有在暗室里观察至少5秒钟之后人们才能感觉到它的发亮。The new project#39;s goals, at least initially, are similarly modest. ;We hope to have a plant which you can visibly see in the dark (like glow-in-the-dark paint), but don#39;t expect to replace your light bulbs with version 1.0,; the project#39;s Kickstarter page says.这项新研究的目标,至少是初步目标,也同样保守。该研究的Kickstarter网页上称:“我们希望能研制出一种在黑暗中可以被看到的植物(就像夜光颜料那样),但是不要指望1.0版本就能取代你的电灯。”But part of the goal is more controversial: to publicize do-it-yourself synthetic biology and to ;inspire others to create new living things.; As promising as that might seem to some, critics are alarmed at the idea of tinkerers creating living things in their garages. They fear that malicious organisms may be created, either intentionally or by accident.而该研究的有些目标则是有争议性的:推广DIY合成生物的理念以及“激励其他人创造新生物”。这在有些人听来可能很是振奋人心,但批评者对这种在自家车库就能创造生物的造物者的想法产生了警惕。他们害怕有可能会制造出有害生物体,不管是故意还是意外。Two environmental organizations, Friends of the Earth and the ETC Group, have written to Kickstarter and to the Agriculture Department, which regulates genetically modified crops, in an effort to shut down the glowing plant effort.两家环保组织地球之友(Friends of the Earth)和ETC组织(ETC Group)已经致函Kickstarter和农业部(Agriculture Department),试图制止对发光植物的研究活动。The project ;will likely result in widesp, random and uncontrolled release of bioengineered seeds and plants produced through the controversial and risky techniques of synthetic biology,; the two groups said in their letter demanding that Kickstarter remove the project from its Web site.这两个组织在要求Kickstarter从其网站上撤销该项目的信中称,这项研究;可能将会导致利用争议性的、危险的合成生物技术制造出的生物工程种子和植物出现大范围的、随机的、不受控制的扩散。”They note that the project has pledged to deliver seeds to many of its 4,000 contributors, making it perhaps the ;first-ever intentional environmental release of an avowedly #39;synthetic biology#39; organism anywhere in the world.; Kickstarter told the critics to take up their concerns with the project#39;s organizers. The Agriculture Department has not yet replied.他们提到,这项研究已经承诺要给4000多名持者分发种子,这或许是“有史以来第一次将一种号称#39;合成生物#39;的有机体有意地在全世界进行环境性释放”。Kickstarter让批评者向项目组织者表达他们的担心。农业部还未对此作出回复。Antony Evans, the manager of the glowing plant project, said in an interview that the activity would be safe.这个发光植物项目的经理安东尼·埃文斯(Antony Evans)在采访中称,这项活动是安全的。;What we are doing is very identical to what has been done in research laboratories and big institutions for 20 years,; he said. Still, he added, ;We are very cognizant of the precedent we are setting; with the do-it-yourself project and that some of the money raised would be used to explore public policy issues.他说:“我们要进行的研究与研究实验室和大型机构在过去20年中一直进行的研究相同。”他还补充称,对DIY项目,“我们十分了解我们正在制造什么样的先例”,一部分筹集来的资金将用于探索公共政策方面的问题。Synthetic biology is a nebulous term and it is difficult to say how, if at all, it differs from genetic engineering.合成生物学是一个模糊的概念,很难把它和基因工程区分开来,或者说根本就分不开。In its simplest form, genetic engineering involves snipping a gene out of one organism and pasting it into the DNA of another. Synthetic biology typically involves synthesizing the DNA to be inserted, providing the flexibility to go beyond the genes found in nature.基因工程最简单的形式是从一个有机体内提取出一个基因,将它植入另一个有机物的DNA中。合成生物学通常是合成一个可供植入的DNA,同时具有可以超出自然界中已有基因范围的灵活性。The glowing plant project is the brainchild of Mr. Evans, a technology entrepreneur in San Francisco, and Omri Amirav-Drory, a biochemist. They met at Singularity University, a program that introduces entrepreneurs to futuristic technology.这项发光植物工程是旧金山一个科技创业者埃文斯和生物化学家奥姆里·阿米拉夫-德罗利(Omri Amirav-Drory)的创意。他们是在奇点大学(Singularity University)一个向创业者介绍未来主义技术的项目上结识。Dr. Amirav-Drory runs a company called Genome Compiler, which makes a program that can be used to design DNA sequences. When the sequence is done, it is transmitted to a mail-order foundry that synthesizes the DNA.阿米拉夫-德罗利经营着一家叫做Genome Compiler的公司,该公司的一个项目可以用于设计DNA序列。排序完成以后,将会传给一个接受邮购的工厂去合成DNA。Kyle Taylor, who received his doctorate in molecular and cell biology at Stanford last year, will be in charge of putting the synthetic DNA into the plant. The research will be done, at least initially, at BioCurious, a communal laboratory in Silicon Valley that describes itself as a ;hackerspace for biotech.;去年在斯坦福大学(Stanford)拿到了分子和细胞生物学士学位的凯尔·泰勒(Kyle Taylor)将负责把合成的DNA植入植物体内。这项研究将在BioCurious实验室完成,至少初步研究如此。BioCurious是一家位于硅谷的公共实验室,它称自己是一个“生物技术的黑客空间。”Whether it will ever be possible to replace light bulbs remains to be seen and depends to some extent on how much of the plant#39;s energy can be devoted to light production while still allowing the plant to grow. Mr. Evans said his group calculated, albeit with many assumptions, that a tree that covers a ground area of 10 meters (nearly 33 feet) by 10 meters might be able to cast as much light as a street lamp.发光植物是否可以取代电灯泡还有待确定,这同时也取决于这种植物在维持生长的同时将会用多少能量制造光亮。埃文斯称,虽然存在很多假设,但他的小组还是计算出,一株可以覆盖100平方米区域的大树或许可以制造出一盏街灯的光亮。While the Agriculture Department regulates genetically modified plants, it does so under a law covering plant pests.虽然农业部对转基因植物进行监管,但借助的却是一项植物病虫害方面的法律。Todd Kuiken, senior research associate at the Woodrow Wilson Center in Washington, who has been studying the governance of both synthetic biology and the do-it-yourself movement, said the glowing plant project was an ideal test case.华盛顿伍德罗·威尔逊国际学者中心(Woodrow Wilson Center)的高级研究助理托德·库伊肯(Todd Kuiken)对合成生物学和DIY运动都进行过研究,他称发光植物工程是一个理想的实验案例。;It exposes the gaps and holes in the regulatory structure, while it is, I would argue, a safe product in the grand scheme of things,; Dr. Kuiken said. ;A serious look needs to be taken at the regulatory system to see if it can handle the questions synthetic biology is going to raise.;库伊肯说:“它暴露了监管结构中的缺失和漏洞,同时我必须要说的是,从大局上来看这是一个安全的产品。必须严格看待监管体系,检验它是否能解决合成生物学将会带来的问题。” /201410/339017惠州早泄治疗大概多少钱 Google Inc. faces intensifying challenges in China after a popular website and Internet browser company there replaced the search service for its own technology. 中国一家人气颇高的网站及互联网浏览器公司用自己的技术替代了谷歌(Google Inc. )的搜索务,由此可见,谷歌在中国面临的挑战正在不断增大。 Qihoo 360 Technology Co. launched its own search engine last week and is in the process of making it the default on its website and browser, said Chief Financial Officer Alex Xu in a Tuesday interview. The Beijing company, whose Internet browser reached about 270 million monthly users in the first quarter, previously offered Google#39;s search technology as the first choice. 奇虎360科技有限公司(Qihoo 360 Technology Co. )首席财务长徐祚立周二在接受采访时说,奇虎360上周推出了自己的搜索引擎,目前正在将其设置为奇虎360网站和浏览器的默认搜索引擎。这家北京公司此前曾将谷歌搜索引擎作为用户的首选。今年一季度,该公司互联网浏览器的月使用人数达到约2.7亿。 Qihoo#39;s move underscores the uphill battle Google faces to penetrate a market dominated by domestic rivals, including Baidu Inc., which holds 78.6% of the search market in the second quarter, according to industry research firm Analysys International. 奇虎360的举动凸显出谷歌在打入一个由百度(Baidu Inc. )等国内竞争对手主导的市场时面临的艰巨挑战。据行业研究公司易观国际(Analysys International)的数据,今年二季度百度在中国搜索市场所占份额为78.6%。 Google#39;s search market share in China has dwindled since it announced in 2010 that it would no longer adhere to China#39;s censorship policies and moved its Web search and other services to Hong Kong, where it doesn#39;t have to comply with regulations in mainland China. Google held 15.7% of China#39;s search market in the second quarter, according to Analysys. 2010年,谷歌宣布不愿再遵守中国内地的审查政策,并把网络搜索和其他务移到了香港。在香港,谷歌不必遵守中国内地的规定。此后,该公司在中国搜索市场的份额一直在下滑。据易观国际的数据显示,二季度谷歌在中国搜索市场所占份额为15.7%。 It isn#39;t clear exactly how Qihoo#39;s decision will affect Google#39;s market share. 奇虎360的决定将对谷歌的市场份额产生怎样的影响目前尚不清楚。 Although Mr. Xu said users will still have the option to select Google#39;s search service, the switch makes it likely that Qihoo#39;s users will use its own services. In the first quarter the company estimated it had 77 million unique visitors per day to its website. 尽管徐祚立说用户仍可选择谷歌的搜索务,但奇虎360改变默认搜索引擎的做法可能会使用户转而使用奇虎360的搜索引擎。该公司估计,今年一季度其网站日独立访问流量为7,700万。 Qihoo#39;s Mr. Xu said that Google#39;s customer service had declined since it made its decision to leave China in 2010, and that Qihoo#39;s aim was to provide a quality search engine for its users. 徐祚立说,自2010年谷歌决定退出中国内地以来,其客户务一直在走下坡路,奇虎360的目标则是为用户提供高质量的搜索引擎。 #39;We believe there is room in China#39;s search market for a search engine that can provide more relevant results at a fast speed,#39; he said. 他说,我们认为,对于一个能够快速提供更多有用结果的搜索引擎来说,中国搜索市场还是有它的空间的。 A Google spokesman in China declined to comment. 谷歌驻中国发言人不予置评。 Not well known outside of China, Qihoo makes revenue by using its popular security software to drive users to its aggregator website, where it sells advertisements and links. 奇虎360在中国以外并不是很有名。该公司利用自己颇受欢迎的安全软件吸引用户访问其聚合网站(它在网站上销售广告和链接),进而创收。 While Baidu dominates the market, analysts say there is room for small players like Qihoo and local search provider Sohu.com Inc. to win ad revenue, which is more resilient in search than other parts of the Internet, like social networking. 尽管百度在中国的搜索市场上占据主导地位,分析人士却说,奇虎360等小公司以及中国本土搜索务提供商搜狐(Sohu.com Inc. )有赢得广告收入的空间。搜索务中的广告比社交网站等互联网其他领域的广告弹性更大。 Google continues to operate offices in mainland China, but its search and other services like Gmail are frequently disrupted by the government#39;s web filtering system. 谷歌在中国内地仍有业务,但其搜索和Gmail电子邮件等其他务常常因政府网络过滤系统的干扰而中断。 Despite its setbacks in China, Google still has a considerable presence there. Its Android mobile operating system was on about 83% of devices sold in the second quarter, according to Analysys, and it continues to run an Internet and mobile advertising business in the country. 尽管在中国内地受阻,谷歌在那里仍有相当大的影响。据易观国际的数据显示,二季度中国销售的移动设备中有约83%搭载的是谷歌安卓(Android)移动操作系统。此外,谷歌在中国内地仍有互联网和移动广告业务。 The shift is the latest in a long-term trend of Chinese Internet companies supplanting Western rivals in the China market. 这种转变是中国互联网公司在中国市场上取代西方对手这一长期趋势中出现的最新进展。 China is aly partially isolated from the rest of the Internet by government censorship efforts, regulatory requirements that include locating servers and other key equipment locally, language and other factors. 由于政府审查、将务器和其他主要设备设在本地等监管要求、语言以及其他因素,中国已经部分地与世界其他地方的互联网隔绝。 EBay Inc. largely withdrew from China in 2006, leaving Chinese e-commerce giant Alibaba Group Holding Ltd. in a dominant position there, while local companies fill the roles of Facebook Inc., Twitter Inc. and Google#39;s YouTube, which are all blocked in China. 2006年,EBay Inc.基本上退出了中国内地市场,使得中国电子商务巨头阿里巴巴集团(Alibaba Group Holding Ltd.)在这一市场占据了主导地位。与此同时,中国本土公司也承担了在中国内地遭屏蔽的Facebook Inc.、推特(Twitter Inc.)和谷歌旗下的YouTube等务的所应扮演的角色。 /201208/196407惠州龙门县妇幼保健人民中医院治疗早泄多少钱

A day I’ll never forget…”谷歌创投(Google Ventures)普通合伙人戴维·克莱恩8月19日在Twitter上写道:“这是10年前的今年。我永远无法忘记的一天……”The object in question was the photo-of-a-photo seen above, of Google executives preparing to ring the opening bell of Nasdaq in New York on August 19, 2004. As Fortune wrote yesterday, Google was a much smaller company then. It was involved in far fewer businesses, had dramatically less revenue, and employed just five percent of the people it does today.他所说的正是上面我们看到的那张图,那是2004年8月19日,谷歌高管团队准备在纽约敲响纳斯达克(Nasdaq)开市钟时的合影。正如《财富》杂志(Fortune)另一篇报道中所写的那样,那时的谷歌还是一家小公司,公司业务比现在小得多,更没有如此巨额的收入,员工人数也只有如今的百分之五。The people on stage for Google’s initial public offering that day didn’t even represent 1% of the company’s employees at the time, but many of them were important to the company’s early success. Below, a list of who those people are, what role they played on that day in 2004, and where they are today.谷歌上市当天,登台的人数甚至不到当时公司总人数的1%,但其中许多人对于公司早期的成功发挥了重要作用。下面是照片中各位人物的介绍,他们在2004年谷歌上市当天的角色,以及他们的现状。In the front row前排Left to right:从左到右:Unknown Nasdaq executive身份不明的纳斯达克高管David Krane—then, Google’s director of Global Communications and Public Affairs;now, general partner at Google Ventures.戴维o克莱恩——时任谷歌全球通信及公共事务部总监;现任谷歌风投普通合伙人。George Reyes—then, Google’s chief financial officer; now, retired.乔治o雷耶斯——时任谷歌首席财务官;现已退休。Eric Schmidt—then, Google’s chief executive officer; now, Google’s executive chairman.埃里克o施密特——时任谷歌首席执行官;现任谷歌执行董事长。Larry Page—then, Google’s president of products; now, Google’s chief executive officer.拉里o佩奇——时任谷歌产品总裁;现任谷歌首席执行官。Robert Greifeld—then and now, Nasdaq’s chief executive officer.

They’re both in the business of “delighting customers” in controlled, predictable environments with convenience and ease of use. They both have huge customer bases (800 million for Apple, 250 million for Amazon). And now they both sell smartphones. For roughly the same price.去年夏天,Asymco的贺拉斯o德迪欧在名为《苹果反对者》(The Anti-Apple)的文章中写道:“苹果(Apple)和亚马逊(Amazon)可谓“大同小异。”两家公司都致力于在受控且可预见的环境中,以便利性和易用性“取悦客户”。两者都拥有庞大的客户群(苹果有8亿用户,亚马逊有2.5亿用户)。而现在,两家公司都在销售智能手机,而且售价基本相同。The main difference is that Apple’s AAPL -0.35% mission, as Tim Cook never tires of saying, is to make the very best products.两者主要的区别在于,苹果的使命是打造最好的产品,这也是苹果首席执行官蒂姆o库克常常挂在嘴边的一句话。Amazon’s Fire doesn’t have to be the best. It just has to be good enough. Its mission is to make impulse buying at Amazon’s AMZN -2.21% growing retail empire even more friction-free. If it does that well – using a point-and-buy feature called Firefly — some portion of those 250 million customers will trade up for one.亚马逊的Fire无需成为最好的产品,它只要足够好就行了。Fire的使命是,使用户能更顺畅的在亚马逊不断扩张的零售帝国进行冲动性购物。如果能通过名为Firefly的扫描购买功能做到这一点,亚马逊的2.5亿用户中,一部分原本使用较低端手机的用户就会购买Amazon Fire手机。But they won’t trade down. Compared with an iPhone, Apple loyalists sniffed Wednesday, Fire’s user interface is “a mess.” It only runs, for now, on ATamp;T’s T 0.45% network. There won’t be a flood of new apps until developers are persuaded that it’s going to take off. And because it uses a forked version of Android, it can’t run apps purchased on either Apple’s App Store or Google GOOG 0.28% Play.但原本使用更高端手机的用户却不会降低标准。上周三,苹果的忠实粉丝对Fire的用户界面嗤之以鼻,说它“一塌糊涂”。目前,Fire仅在美国电话电报公司(ATamp;T)的网络上运行。除非开发者们相信Fire将大热,否则不会有大量针对这款手机开发的应用。而由于采用Android的分版本,Fire无法运行苹果应用商店(App Store)或谷歌(Google)Play平台上购买的应用。Still, it’s better than a flip phone. It comes with 12 months of free Amazon Prime shipping. Its camera is said to be excellent. It boasts some whizzy features (3D, Mayday, scroll’n’roll). And Bezos is not too proud to stick an ad for it in the face of every Amazon user who logs on. Unless Fire melts down in real-world usage, it will probably succeed in establishing a beachhead in an over-crowded smartphone market dominated by Apple (which skims off the cream) and Samsung (which, if you’ll pardon a badly mixed metaphor, mops up most of the rest).不过,Fire还是比翻盖手机强:它自带1年免费Amazon Prime快递务;它的摄像头据说相当好;它还有一些出色的功能(包括3D、求救以及scroll#39;n#39;roll功能)。而且贝佐斯大肆为Fire向每位登陆亚马逊的用户做广告。除非Fire在实际使用中出问题,否则它很可能将在由(把持高端市场的)苹果和(统治中低端市场的)三星(Samsung)配的过度饱和的智能手机市场占据一席之地。One more difference between Amazon and Apple, perhaps the most important:亚马逊和苹果还有一个或许是最重要的区别:Apple’s iTunes user base is growing exponentially but its sales per user are falling. Amazon’s user base is growing arithmetically, and its sales per user are relatively flat. (See Horace Dediu’s charts, reproduced below.)苹果的iTunes用户群正呈几何级数增长,但单位用户销售额正在下降。亚马逊用户群的增长没那么迅猛,单位用户销售额也比较平稳。(贺拉斯o德迪欧给出的图表转载如下。)“Apple’s user growth is a function of expanding its device portfolio and distribution,” Dediu wrote in April. “Amazon’s user growth is a function of expanding its logistics and merchandise mix. This is also not easy to do globally. Arguably, Amazon cannot scale in the exponential rates seen by Apple… because it has to depend on trucks and roads and regulators to complete most of its sales.”德迪欧在四月份写道:“苹果的用户增长是扩大设备组合及分销的结果。而亚马逊的用户增长是扩大物流和商品组合的结果。后者难以在全球范围内实现。可以说,亚马逊无法获得苹果那样的几何级数式增长……因为它大部分销售的完成必须依赖卡车、道路和监管机构。” /201406/307287惠州韩式包皮医院哪里好惠州哪家做包皮手术好
