It#39;s no secret celebrities spend thousands upon thousands of dollars on maintaining their looks.世人皆知,明星们为了使自己容颜永驻可谓是不惜一切代价。From bloody #39;vampire facials#39; to placenta serums and of course plastic surgery - the fountain of youth runs deep.从敷人血面膜驻颜到胎盘面部护理,明星们为了看起来更年轻真是使出了浑身解数。But an app is now trying to cut through all the cosmetics to determine exactly how old a person looks based on a picture.但现在有一款应用,能够识破你所有“伪装”,仅从照片判断你的年龄。(有人将奥巴马最开始的照片和现在的照片年龄进行对比,发现他任职6年,颜龄老了13岁。今年这位总统53岁,照片显示已有58岁。)(虽然已经51岁,米歇尔夫人却被测出只有37岁。奥巴马总统曾经说过:“米歇尔一天都没有变老,我问她青春永驻的秘密是什么,她只是说,‘新鲜的水果和蔬菜#39;,这太让人恼火了。”) The website, called How old do I look, it allows people to analyse any image found on Bing, Microsoft#39;s search engine, or upload their own.这个通过分析图片来鉴定年龄的网站叫How old do I look,人们可以上传从微软搜索引擎必应(Bing)上下载的图片,或上传自己的图片,系统将对图片进行分析。(乔治王子显示的年龄就是他的实际年龄,但是十分遗憾的是,软件搞混了他的性别。) It even allows users to search for celebrities - and see what Microsoft thinks their real ages are.用户甚至可以在该网站上搜索名人的照片,应用将会测算出该名人的“真实年龄”。#39;This may be hard to believe but it took a couple of developers just a day to put this whole solution together, starting with the pipeline from the web page to the Machine Learning APIs to the real time streaming analytics and real time B,#39; said Microsoft.“这个应用是两个研发人员的劳动成果,他们完成了从网页到机器学习编程接口(Machine Learning APIs)的信息传输,继而完成后者到实时流量分析,再到实时扫描的信息传输,整个过程仅用了一天时间,这非常不可思议。”微软有关人员表示。(67岁高龄的希拉里·克林顿经过软件分析后显示只有40岁。这张照片选自她的竞选宣传片“我想成为捍卫者”。) It designed to site to show off the capabilities of its cloud server software.微软设计这个网站是为了体现其云务器软件的性能。(照片中51岁的普京实际年龄已经是62岁了。) It revealed the site today at its annual Build developers conference in San Francisco.在当地时间4月30日于旧金山举办的年度Build开发者大会上,微软公布了这个网站。(比尔-盖茨实际年龄59岁,而自家公司开发的软件测算的年龄居然已经77岁了。) #39;We wanted to create an experience that was intelligent and fun could capture the attention of people globally, so we looked at the APIs available in the Azure Machine Learning Gallery,#39; it said.微软表示:“我们想开发一款足够智能的产品,抓住全世界人们的目光,因此我们在Azure机器学习库(Azure Machine Learning Gallery)中查找可利用的编程接口(APIs)。”The system works by analysing 27 points on the face.这个系统将在人的面部选取27个点并进行分析。(美国乡村音乐小天后泰勒·斯威夫特的这张照片摄于她23岁时,软件却认为泰勒的颜龄就像她的流行单曲“22”一样。) Called face landmarks, they are a series of specifically detailed points on a face; typically points of face components like the pupils, canthus or nose.系统将这27个点称为“脸部地标”,选取的是一系列非常能够体现面部特征的点;尤其是像瞳孔,眼角和鼻子。(足球明星大卫·贝克汉姆刚于上周五过了他40岁的生日,软件测的结果是45岁。) #39;These attributes are predicted by using statistical algorithms and may not always be 100% precise.“该应用是通过统计学算法来对这些特征进行测算,有时并非百分之百准确。”(“颜龄”认为默克尔只有47岁,比实际年龄小了11岁。不过,照片中在默克尔身边的时任泰国总理英拉更抢镜,只有29岁,要知道当时英拉的实际年龄是45岁。) #39;However, they are still helpful when you want to classify faces by these attributes.“然而,当我们想要通过这些特征来鉴别人的面部时,这个应用仍然有其用武之地。”(这两年,爱折腾的安倍老得快,“颜龄”测试给出的结果是73岁。)#39;Face landmarks are a series of specifically detailed points on a face; typically points of face components like the pupils, canthus or nose.“‘脸部地标#39;是脸部一系列非常能够显示面部特征的点;尤其是像瞳孔,眼角和鼻子。Face landmarks are optional attributes that can be analyzed during face detection.“脸部地标”是在脸部随机选取的特征点,系统会对人脸部进行识别,继而对这些特征点进行分析。By default, there are 27 predefined landmark points.默认情况下,系统将预先确定27个这样的“脸部地标”。 /201505/373659The ability of the Amazon forest to soak up excess carbon dioxide is weakening over time, researchers reported last week. That finding suggests that limiting climate change could be more difficult than expected.研究人员上周撰文称,亚马孙森林吸收二氧化碳的能力正在逐渐削弱。这一研究结果显示,遏制气候变化可能比预期的更加困难。For decades, Earth’s forests and seas have been soaking up roughly half of the carbon pollution that people are pumping into the atmosphere. That has limited the planetary warming that would otherwise result from those emissions.几十年来,人类排放到大气中的二氧化碳污染,有将近一半都会被森林和海洋吸收。这抑制了地球因为那些排放而变暖的程度。The forests and oceans have largely kept up even as emissions have skyrocketed. That surprised many scientists, but also prompted warnings that such a robust “carbon sink” could not be counted on to last forever.尽管二氧化碳排放急剧提高,但是森林和海洋的吸收能力基本上跟上了增长的步伐。这让许多科学家感到意外,不过也令一些人发出了警告:不能指望这样一个强劲的碳吸收源永远运转下去。In a vast study spanning 30 years and covering 189,000 trees distributed across 321 plots in the Amazon basin, researchers led by a group at the University of Leeds, in Britain, reported that the uptake of carbon dioxide in the Amazon peaked in the 1990s, at about 2 billion tons a year, and has since fallen by half.由英国利兹大学(University of Leeds)一个研究小组引领的研究人员,持续30年对亚马孙盆地321块林地中的18.9万棵树进行了研究。他们发现,亚马孙森林吸收二氧化碳的总量在20世纪90年代达到峰值,每年约20亿吨,自那时以来已经下降了一半。Initially, the researchers postulated, the Amazon may have responded well to rising carbon dioxide levels, which are known to increase plant growth, but that response appears to be tapering off. Drought and other stresses could be playing a role, but the main factor seems to be that the initial acceleration of growth sped up the metabolism of the trees.研究人员最初推断,面对二氧化碳水平的提升,亚马孙森林可能应对良好,二氧化碳可以促进植物生长。但是亚马孙森林的应对能力似乎正在减弱。干旱和其他问题似乎也起到了一定影响,不过主要的因素似乎是最初生长速度的加快,加速了树木的新陈代谢。“With time, the growth stimulation feeds through the system, causing trees to live faster, and so die younger,” Oliver L. Phillips, a tropical ecologist at the University of Leeds and one of the leaders of the research, said in a statement.“随着时间的推移,刺激生长的效应传到整个系统,导致树木长得更快,所以也死得更早,”利兹大学热带生态学家奥利弗·L·菲利普斯(Oliver L. Phillips)和另一位在研究中牵头的人物在一份声明中说道。Further research is needed, but the scientists say that climate forecasting models that assume a continuing, robust carbon sink in the Amazon could be overly optimistic.虽然还需要进一步开展研究,但科学家表示,假定亚马孙森林会持续吸收大量二氧化碳的气候预测模型,可能过于乐观了。At a global scale, studies suggest that forests are still absorbing far more carbon than they release into the atmosphere, even as stresses like fires and beetle attacks increase because of climate change. In essence, rising forces of growth have been outracing rising forces of death in the world’s forests.在全球尺度上,研究显示森林吸收的碳仍然远远超出它们向大气中释放的碳,尽管由气候变化造成的火灾、虫害等消极事件有所增加。简而言之,在全世界的森林中,树木生长的趋势远远超出了树木死亡的趋势。Perhaps the big question now is whether that will flip. Will forests beyond the Amazon, such as the boreal forest that encircles the Northern Hemisphere, eventually follow the Amazon and weaken as carbon sinks?现在最大的问题或许是,这种局面会不会发生逆转。亚马孙之外的森林,如环绕北半球的针叶林带,是不是最终也会像亚马孙森林一样,减弱吸收二氧化碳的能力?That would mean, in effect, that human civilization would have less help from trees, and cuts in carbon emissions would need to be sharper than previously thought to limit global warming to tolerable levels.那实际上意味着,人类文明能从树木那里得到的帮助就会减少,削减二氧化碳排放的力度,需要超出过去预想的力度,以将全球变暖控制在可接受的水平。“Forests are doing us a huge favor, but we can’t rely on them to solve the carbon problem,” Dr. Phillips said. “Instead, deeper cuts in emissions will be required to stabilize our climate.”“森林给我们帮了大忙,但是我们不能靠它们来解决碳排放的问题,”菲利普斯说。“要想稳定我们的环境,还是需要更有力地削减排放。” /201503/366715
