Microsoft jolted fixed income investors to life on Monday when it sold nearly bn of debt to fund its takeover of social network LinkedIn, the fifth largest corporate bond sale on record.本周一,为了给收购社交网络领英(LinkedIn)提供资金,微软(Microsoft)发行了近200亿美元债券,其规模在企业债券发行史上排名第五,为固定收益投资人注入一剂强心针。The sale from the triple-A rated company, one of only two US corporates to hold the opinion from Standard amp; Poor’s, was met with intense demand as portfolio managers search out income. Trillions of dollars of sovereign and corporate debt are currently trading with a yield below zero.作为美国仅有的两家获标普(Standard amp; Poor’s)AAA评级的企业之一,微软此次发售债券获得了寻求收益的投资组合经理的热烈欢迎。当前有数万亿美元主权和企业债券都是在零利率以下交易的。The US software maker, which agreed to a bn acquisition of LinkedIn in June as part of chief executive Satya Nadella’s efforts to revitalise growth, issued .75bn of debt with seven maturities, according to three people familiar with the deal.据该交易的三名知情人表示,微软此次发行的债券分七种年限,发行规模为197.5亿美元。这家美国软件制造商在今年6月同意以260亿美元收购领英,这是微软首席执行官萨蒂亚#8226;纳德拉(Satya Nadella)为恢复增长作出的努力的一部分。Order books for the Microsoft sale eclipsed bn, the three people said, with demand strongest for 10- and 30-year paper. The sale, which ranks behind offerings from Verizon, Anheuser-Busch InBev, Actavis and Dell, was composed of fixed-rate notes maturing in between three and 40 years.微软此次债券发行认购规模超过500亿美元,需求最强的为10年期和30年期的债券。此次债券为固定收益率,到期年限在3年期至40年期之间,发行规模仅次于Verizon、百威英(Anheuser-Busch InBev)、阿特维斯(Actavis)和戴尔(Dell)。The transaction included bn of 10-year notes, which priced with a yield 90 basis points above the benchmark US Treasury, or roughly 2.42 per cent. New 30-year bonds priced with a yield of 3.73 per cent, 5 bps above existing debt that matures in 2045.该交易包括40亿美元10年期债券,利率高于基准美国国债90个基点,约为2.4%。此次新发30年期债券利率为3.73%,较2045年到期的现有债券高出5个基点。Both Samp;P and Moody’s affirmed their triple-A opinions of Microsoft on Monday despite the significant increase in the company’s debt burden.尽管微软债务负担明显加重,但标普和穆迪(Moody’s)在周一都再次重申对微软的AAA级评级。Bank of America Merrill Lynch, JPMorgan and Wells Fargo led the underwriting of the sale.美银美林(Bank of America Merrill Lynch)、根大通(JPMorgan)和富国(Wells Fargo)牵头此次债券发行工作。 /201608/458433If you’ve ever stared enviously at an ant, jealous of its six-legged efficiency, then you’ll be happy to hear that engineers at Japan’s Inami Hiyama Laboratory have developed a multi-limbed robotic suit – able to give users control over two extra arms.如果你曾羡慕地盯着一只蚂蚁,嫉妒它六条腿的效率,那么你会很高兴听到这则消息,日本稲見?檜山研究所的工程师开发了一套多臂机械套装,可以使用户控制另外两条手臂。The MetaLimbs system is built up of two main parts: The first is a set of robotic limbs that rest on the wearer like a tech-heavy backpack. The second is a tracking system attached to the wearer’s legs.金属壁系统由两个主要部分构成:第一部分是一套机械臂,它就像一个高科技的双肩背包一样背在佩戴者身上。第二部分是一个附着在佩戴者腿上的追踪系统。Optical markers are attached to toes and knees. When the wearer moves their leg, so does the accompanying robotic arm. When they squeeze their toes, the robot hand tightens its grip.光学指示器附着在脚趾和膝盖上。当佩戴者移动他们的腿部时,附属的机械臂也会移动。当他们挤压脚趾,机械臂就会牢牢握紧。There’s also haptic feedback, so when wearer holds something they feel pressure on their foot.这套机械臂还有触觉反馈,所以当佩戴者握住某物时,他们的足部就会感受到压力。Although the demo highlights the use of additional limbs alongside the upper body, it seems the most immediately useful case for the technology would be for those who have lost the use of their arms.虽然样品演示突出了上半身外加手臂的用途,但这种技术立竿见影的有效实例似乎就是为那些失去手臂的人所用。Being able to shift control of the legs to an exterior set of limbs is a useful way to rejig body functionality for those with disabilities. It would be interesting, for example, to see if a similar system could move in the opposite direction – with artificial legs controlled by arm movements.对于那些身有残疾的人来说,能够通过腿部来控制一套外置手臂是调整身体功能的一种有效方式。设想一下,一套相似的系统是否可以反向操作,例如通过移动手臂来控制义肢,这会很有趣。Beyond this, the project raises interesting questions about the concept of the human body, and how it can be reorganised with the help of advanced prosthetics.除此之外,这个项目提出了关于人体概念的有趣问题,借助先进的修复术可以如何重组人体?It is a novel experience, your body will adapt to a new type of human shape and the body schema will metamorphose [to encompass] multiple arms.这是一项新奇的体验,你的身体会适应一种新式的体型,而且身体架构会变得可以附着多条手臂。 /201706/513359For weeks, Facebook has been questioned about its role in sping fake news. 几个星期以来,Facebook一直因其在假新闻传播过程中扮演的角色而遭到质疑。Now the company has mounted its most concerted effort to combat the problem.目前,该公司正采取步调最为一致的行动来解决这一问题。Facebook said Thursday it had begun a series of experiments to limit misinformation on its site. Facebook周四表示,公司已经着手推进一系列试验性举措,旨在遏制其网站上虚假信息的传播。The tests include making it easier for its 1.8 billion members to report fake news, and creating partnerships with outside fact-checking organizations to help it indicate when articles are false. 这些试验包括:让其18亿名用户可以更加容易地举报假新闻,并与外部事实核查机构建立合作关系,以便及时就内容虚假的文章做出提示。The company is also changing some advertising practices to stop purveyors of fake news from profiting from it.此外,该公司正在改变某些广告业务惯例,为的是防止假新闻供应者从中获利。Facebook is in a tricky position with these tests. 开展这些试验的Facebook处境颇为尴尬。It has regarded itself as a neutral place where people can freely post, and view content. 它一直将其网站视作一个中立的地方,人们可以在上面自由地发布、阅读和观看内容。But as its reach and influence have grown, it has had to confront questions about its moral obligations and ethical standards regarding what appears on the network.但随着它的传播范围和影响力与日俱增,它不得不面对与出现在其网站的信息有关的道德义务和伦理标准问题。Its experiments on curtailing fake news show that Facebook recognizes it has a deepening responsibility for what is on its site. Facebook开展的这些旨在遏制假新闻传播的试验表明,它意识到自己对出现在自家网站上的内容负有深切的责任。But Facebook is wary of exposing itself to claims of censorship.但Facebook颇为谨慎地避免宣称这是在进行审查。We really value giving people a voice, but we also believe we need to take responsibility for the sp of fake news on our platform, said Adam Mosseri, 我们非常珍视的是,给人以发声渠道,但我们也认为,我们需要对假新闻在自家平台上的传播负起责任,Facebook负责信息流业务的副总裁亚当#8226;莫塞里(Adam Mosseri)表示。a Facebook vice president who is in charge of its News Feed, the company’s method of distributing information to its global audience.该公司通过这项业务向全球受众推送信息。Fake news is not confined to Facebook, 假新闻不只存在于Facebook上。with a vast ecosystem of false news creators who thrive on online advertising and who can use other social media and search engines to propagate their work. 假新闻制造者已经形成了一个巨大的生态系统,他们靠在线广告发展壮大,可以利用其它社交媒体和搜索引擎推广他们的作品。Google, Twitter and message boards like 4chan and Reddit have all been criticized for being part of that chain.谷歌(Google)、Twitter以及4chan、Reddit等论坛都是这个链条上的一员,也都因此受到了批评。Still, Facebook has taken the most heat over fake news. 不过,Facebook承受了假新闻问题所引发的大部分愤怒。The company has been under that spotlight since Donald Trump was elected president. 自从唐纳德#8226;特朗普(Donald Trump)当选总统以来,该公司一直处于聚光灯下。Trump’s victory led people to focus on whether Facebook had influenced the electorate, especially with the rise of hyperpartisan sites on the network and many examples of misinformation.特朗普的胜利导致人们聚焦于Facebook 是否曾影响选民,尤其是利用其网站上出现的一批党派色极强的专页以及许多虚假信息来施加影响。Mark Zuckerberg, Facebook’s chief executive, has said he did not believe the social network had influenced the election result.Facebook的首席执行官马克#8226;扎克伯格(Mark Zuckerberg)表示,他并不认为Facebook影响了大选结果。 /201612/484256

Soon, your phone#39;s cracked screen may have its own healing factor.在不久的将来,摔碎的手机屏幕或将能够自我修复。Scientists from the Department of Chemistry at the University of California, Riverside have developed a self-healing material that has potential applications for phone screens, artificial muscles, and more.来自加利福尼亚大学河滨分校化学系的科学家们研发出一种具有自我修复功能的新型材料。该材料或许可以应用于手机屏幕、人造肌肉以及其他更多领域。The concept isn#39;t exactly new. In late 2013, the LG G Flex came out with a self-healing back that automatically repaired scratches and other wear and tear in a matter of minutes. The Flex#39;s material was non-conductive, so it couldn#39;t be used on screens.这并不是一种全新的概念。早在2013年年底,LG公司推出的G Flex手机便在其背壳中使用了一种自我修复材料,该材料可在几分钟之内自动修复划痕以及其他表面磨损。但因为不具备导电性,所以无法应用于手机屏幕。This new material is ;transparent, self-healing, highly stretchable material that can be electrically activated and could be used to improve batteries, electronic devices, and robots,; according to a blog post from UC Riverside.加利福尼亚大学河滨分校官网上的一篇文写道,这种新研发的材料“外观透明,具有自我修复性功能和高延展性”,“该材料具有电活性,可用于提升电池、电子设备和机器人的性能”。Chao Wang, one of the authors of the paper, ;developed an interest in self-healing materials because of his lifelong love of Wolverine, the comic book character who has the ability to self-heal.;研究论文作者之一王超表示,他研究自我修复材料的兴趣起源于一种自己长期以来都很喜爱的动物——狼獾,它们常常出现在连环画里,具有很强的自我修复能力。Christoph Keplinger, another author of the paper, has previously demonstrated that these stretchable, transparent materials can be used to create transparent loudspeakers. With the additional ability to self-heal, the new material is ideal for electronics. The material is both low-cost and strong and can fix itself by resting for 24 hours at room temperature.先前,该研究论文的另一位作者克里斯托弗·凯普林格曾明这些具有延展性的透明材料可用于生产透明扬声器。如今再加上自我修复功能,这种新型材料是生产电子设备的绝佳材料。该材料不仅成本低,而且材质坚固,置于室温中24小时便可进行自我修复。While it may sound futuristic, Wang expects to see materials like the one developed by his lab in production in as little as three years.这些设想的实现听上去似乎遥不可及,但王超预计像他所在的实验室研发的这种新型材料再有三年就能投产。;Within three years, more self-healing products will go to market and change our everyday life. It will make our cellphones achieve much better performance than what they can achieve right now,; Wang told Business Insider.他向商业内幕网透露:“三年之内,会有更多具有自我修复能力的产品进入市场,并且改变我们的日常生活。未来的手机产品将会拥有比现在更好的性能。” /201704/505028

有了老公 每周多做七小时家务?!Men create more housework for women Having a husband creates an extra seven hours of housework each week for women, according to a new study. For men, tying the knot saves an hour of weekly chores."It's a well-known pattern," said lead researcher Frank Stafford, an economist at University of Michigan's Institute for Social Research. "Men tend to work more outside the home, while women take on more of the household labor."He points out individual differences among households exist. But in general, marriage means more housework for women and less for men. "And the situation gets worse for women when they have children," Stafford said.Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are pitching in more, more than doubling their housework hours from six in 1976 to 13 in 2005.Stafford analyzed time-diaries and questionnaires from a nationally representative sample of men and women over a 10-year period from 1996 to 2005. The federally-funded study showed that, both the men and the women who got married did more housework than those who stayed single."Marriage is no longer a man's path to less housework," he said.Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most - about 21 hours a week.Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single guys worked the hardest around the house, trumping all age groups of married men.Having kids boosts house chores even further. With more than three kids, for instance, wives took on more of the extra work, clocking about 28 hours a week compared with husbands' 10 hours. 一项最新研究发现,女人有了老公后每周得多做七个小时的家务活,而对于男人而言,结婚则意味着每周少做一小时的家务。密歇根大学社会研究所的经济学家、首席研究员弗兰克#8226;斯坦弗德说:“‘男主外,女主内。’这是一个众所周知的家庭分工模式。”斯坦福德指出,尽管各个家庭间会存在个体差别,但总的来说,女性婚后承担的家务活增多,而对于男性而言则是减少。“有了孩子后,女性的家务活负担会进一步加重。”不过随着时代的发展,美国家庭的家务活分工情况总的来说还是有所变化。1976年,女性每周花在家务活上的时间为26个小时,而2005年为17个小时;如今男性做家务的时间比过去增加了一倍多,从1976年的每周六个小时增加到了2005年的每周13个小时。斯坦福德对一组具有全国代表性的男性和女性十年的时间使用日记和调查问卷进行了分析,这些数据资料的时间跨度为1996年至2005年。该项由联邦政府提供资金持的研究发现,与单身人士相比,已婚男女做的家务活更多。斯坦福德说:“由此看来,对于男性而言,结婚不再意味着少做家务。”研究发现,二三十岁的单身女性做的家务活最少,每周做家务的时间约为12个小时,六七十岁的已婚女性做的家务活最多,每周约为21个小时。而男性的模式则有所不同,年龄较大的男性比年轻男性做的家务活多。单身男性最勤快,他们做家务的时间超过了各个年龄段的已婚男性。而有了孩子后,家务活负担会进一步加重。妻子承担了更多增加的家务,如果孩子数量超过三个,她们每周做家务的时间会增加到28个小时,而丈夫仅为10个小时。 /200804/34095
