政治倾向由生理决定，而非理智

wmr 写道"人们都愿意相信，自己的政治倾向是由理智决定，而实际是由生理性质决定。基因和环境造成的倾向会扭曲人们对各种事件的认知和思考。虽然可能会因重大经历有所改变，但类似于性格特点，政治倾向在人的一生中一般会保持稳定。
左派（改革的支持者）报告自己同理心更强，愿意寻求新体验。右派（传统的支持者）报告自己小心、礼貌、纯洁、区分团体区别，重视安全、一致和传统。实验室发现他们更注重环境的负面，如果信息有可能是负面则更懒得调查信息，也更容易记住负面信息。当看到负面图片时，他们的交感神经系统也更加活跃。声音突然刺激时，他们的惊吓反射也更强。可能是因为有较大的杏仁体和较小的前扣带。人做出决定的方式可分为两种：有意识的和无意识的。有意识的部分有逻辑性但又慢又懒；无意识的部分快且自动，为你作出大多数事情的决定。看上去自主的决定其实是无意识自动作出的，你还不愿意承认，要用你的有意识思维为那些无意识作出的决定发明一个理由当作借口，装作是有意识作出的。

加拿大魁北克省在1974年通过了一个官方语言法，规定法语是魁北克省唯一的官方语言。这项法律被用于强迫企业业主修改标志，确保法语比其它语言占据更高的地位。现在，魁北克的语言警察将触手伸到了社交网站Facebook。魁北克省切尔西的一家商店Delilah in the Parc的店主Eva Cooper收到了魁北克省语言办公室的一封信函，要求她将商店Facebook页面中所有内容翻译成法语。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

2005年，MIT的三名研究生 Jeremy Stribling、Dan Aguayo和Maxwell Krohn开发了一个计算机程序生成随机的论文，递交到WMSCI 2005会议，被作为"非评审论文"成功接受。三人随后公开他们的程序SCIgen，免费提供下载。于是全世界的研究人员也玩起了递交机器生成论文的恶作剧。法国研究员Cyril Labbé发现，知名的科学期刊出版商Springer出版了16篇假论文，而IEEE出版了100多篇假论文。举一个例子，2013年成都举行的《 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering》会议发表了一篇论文《TIC: a methodology for the construction of e-commerce》，其摘要明显是胡言乱语。对于越来越多的机器生成论文，期刊出版商有应对之策，他们也开始使用程序将假论文筛选出去，但不知名的期刊或会议可能不会愿意在这方面进行投资。

英国宣布了有关如何使用来自三个人的精子和卵子人工生育婴儿的规则。规则草案将征询公众意见，预计可能将在2014年底前实施。医生说，使用来自三个人的精子和卵子人工受孕生育的婴儿可以避免一些由母亲遗传给婴儿的疾病。但反对人士认为，这种做法不道德，并可能让英国"滑向"人工制造婴儿的境地。医学界认为，使用父母的精子和卵子，再加上一个自愿者捐献的卵子可以避免线粒体病（mitochondrial disease）。平均每6500个婴儿里，就有一个有严重的线粒体病，它使得人体细胞缺乏能量，导致肌肉乏力、失明、心脏病、残疾甚至死亡等各类疾病。医学专家开发出两种技术，可以让母亲既将遗传信息遗传给婴儿，同时又通过一个捐献的、有正常线粒体的卵子避免婴儿有线粒体病。英国卫生部早已批准了上述技术。它表示，公众咨询并不是针对是否允许这种技术，而是如何实施。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

波音公开了一则视频，披露了自毁手机Black的更多细节，它的硬件规格要明显落后于今天流行的Android手机：4.3英寸540x 960分辨率显示屏，双核1.2 GHz Cortex A9 CPU，1590 mAh电池，支持双SIM卡，支持LTE、WCDMA和GSM，基于硬件的储存加密。Black是基于私有的安全框架PureSecure，有一个可信引导模式能阻止root，它的双SIM卡一个用于商用移动网络，一个则用于私有的政府网络，手机可以在两个网络之间切换，而当连上一个商用网络，限制用于政府网络的数据和功能将会被锁定。这款安全手机显然不是提供给一般的政府雇员使用，而让人感到讽刺的是，波音雇员也不会使用Black，而是仍然使用黑莓。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

总部位于东京的比特币交易平台MtGox宣布申请破产保护，声称损失了客户的75万比特币和它自己拥有的10万比特币——根据目前的比特币币值，MtGox损失4.73亿美元。MtGox CEO Mark Karpeles称，巨额比特币丢失的原因是交易系统的一个漏洞所致，他对给客户带来的麻烦表示歉意。该公司律师在日本东京一家法院的新闻发布会上说，MtGox的债务（65亿日元）超过了资产（38.4亿日元）。MtGox二月初宣布暂停比特币提款后一直遭到投资者的谴责，远至英国和澳大利亚的客户亲自来到MtGox东京办公室外抗议，本周二MtGox突然关闭了交易和网站。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

Shawn the R0ck 写道"来自Gnome官方网站的信息，2014年Gnome东亚峰会将在北京航空航天大学举行，时间为5月24日至25日。GNOME 3.12将在会议之前发布，会上对新的桌面模式进行交流，会议欢迎新手和有经验的人给予更多建议，以帮助Gnome开拓了许多新的功能和增强功能。 GNOME基金会亚洲委员会在2008年成立，Linuxeden发现旨在通过举办GNOME.Asia亚洲峰会在亚洲地区推广GNOME项目，推广自由开源软件的理念。成立六年来，分别在中国北京、越南胡志明、中国台北、印度班加罗尔、中国香港和韩国首尔举办了六届GNOME.Asia亚洲峰会，GNOME.Asia峰会与GUADEC（GNOME Users And Developers European Conference）和Boston峰会一起成为了GNOME基金会每年的三大活动之一。 通过这六年来的本地化推广活动，GNOME项目的亚洲知名度和活跃度均有大幅提高，特别是亚洲开发者逐渐成为GNOME项目的中流砥柱。也通过这六年的推广，使更多的人们了解和知道了自由软件/开源软件，并深受影响而贡献到各个开源项目中，为丰富和发展全球的开源世界作出自己的贡献。Gnome桌面已经成为主流Linux发行版本的默认桌面，这也是因为Gnome自身的稳定性和成熟性决定，尽管Gnome shell相对于Gnome 2有太大的变化。"This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

从伯明翰到深圳到洛杉矶，全世界的城市都在安装LED路灯，LED灯省钱省电更安全，但改造现有的基础设施和安装LED路灯需要大量的前期费用，很多城市都不具备这个条件。现在飞利浦和爱立信提供了一种方案：照明即服务模式——结合了飞利浦的LED路灯和爱立信的迷你蜂窝基站。也就是说，大规模安装LED路灯的城市可以向电信公司出租迷你蜂窝基站服务，然后用电信公司的钱支付基础设施改造费。飞利浦声称，LED路灯比传统路灯能节省50%到70%的电。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

明报前总编刘进图周三早上遭乘摩托车的袭击者伏击，背部和双腿被连砍六刀。目前刘经过抢救已经醒来但仍处在危急状况。知名记者袭击一事引发了对香港新闻自由的担忧，《明报》则宣布悬赏100万捉拿袭击者，在读者捐赠之后，赏金已经提高到了300多万，该报发表社论称，这次袭击"对新闻工作者已经起到一种无以名状的感受，就是免于恐惧的自由渐行渐远"。香港以前发生过多起类似的记者遇袭案例，大多没有侦破，香港警方将这次事件定性为"典型的三合会案件"，三合会就是香港的黑社会。这次袭击案已成为香港与大陆紧张关系的又一个导火索，新闻网站上的很多评论认为，北京是这次袭击的直接或间接的幕后黑手，因为被袭击者曾负责发表过经常是激烈批评中国政府的报道。官媒《环球时报》则发表评论称，在未抓到凶徒前，暗示某些人或力量是谋划者是高度不负责任，香港反对派暗示刘因得罪内地高官而遭不幸，是"毫无根据地在舆论中给案件提前定性"，应受谴责。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

《卫报》援引前NSA合同工 Edward Snowden泄漏的机密文件报道，英国情报机构GCHQ有一个代号为 Optic Nerve的监视项目，文件显示，在2008年到2010年之间Optic Nerve项目拦截了全世界数百万雅虎用户的视频聊天，以每五分钟截一次图像的频率收集聊天对象的静态图像，不管这些用户是不是监视目标。GCHQ在其中一份文件（如图）称，有3%到11%的雅虎用户参与了裸聊，对视频聊天中展示"讨厌的"裸体的用户数量之多感到吃惊。雅虎发言人表示，他们对GCHQ的数据收集行动并不知情，称如果报导属实，那么这代表了对用户隐私的侵权达到了新的高度，是完全无法接受的。雅虎的聊天工具没有使用加密，该公司表示将会在2014年3月底给予用户选择，加密所有流入流出雅虎服务的数据。GCHQ还尝试使用面部识别技术搜索与监视目标的脸部相似的雅虎用户，它坚称其行为是合法的。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

量子密钥分配系统被认为能用于发送绝对保密的信息，因此全世界的政府、军方和商业机构都在积极探索量子通信。此前有媒体报导称，中共的十八大就使用了量子通信，而科学家也曾经在陆地上完成144公里的量子链路。那么一个问题是，水下呢？水下也有潜水艇和各种传感器，它们是否也能利用量子通信？青岛海洋大学的Peng Shi和同事在预印本网站arXiv上发表研究报告，认为水下量子通信在短距离内是可能的。研究人员计算了光子在保存其携带的量子信息的同时能传输多远，结果是水下量子通信系统在清澈海水中能最远传输125米。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

《纽约时报》报道，美国2到5岁儿童的肥胖率过去十年下降了43%。这是肥胖率首次出现大规模的下降。肥胖会增加癌症、心脏病和中风风险。美国儿童变瘦的趋势令研究人员喜出望外，研究发现儿童如果在2到5岁时超重或肥胖，那么成年后超重或肥胖的可能性比其他人高5倍。2012年美国2到5岁儿童的肥胖率为8%，而这个数据在2004年为14%。肥胖率下降的原因可能有很多，比如美国儿童现在从含糖类饮料中消耗更少的热量，更多女性用母乳喂养，研究人员还记录到儿童摄入的总体热量下降。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

美国西弗吉尼亚州参议员Joe Manchin (D-WV)在致函金融监管机构的信中呼吁美国封杀比特币，但没有提供如何实施禁令的解决方案。比特币等去中心化的数字货币实际上不可能被封杀。参议员在信中说，有许多国家及其央行都对比特币的使用发出警告，其中有两个国家——中国和泰国已经发出了禁令（事实上中国并没有发出禁令，中国的比特币交易平台仍然很火爆），韩国则表示不会认可比特币为合法货币，部分欧盟国家也表示考虑监管或禁止使用比特币。他表示，美国作为世界的领袖和银行业的中心，没有率先做出表率令人失望。他认为是时候采取行动了。他的建议引起了许多人的嘲笑。

Opera迎来丰收的一年

当Opera CEO Lars Boilesen说他们更关心用户而不是金钱的时候，那是因为过去一年他们的收入和利润创下了记录。Opera过去一年很忙：1.55亿美元收购Skyfire，放弃自己的Presto引擎改用WebKit/Blink，发布了基于Blink的第一个版本。而在此期间，Opera股价从年初的31.90挪威克朗增加到年末的82.95挪威克朗，翻了一番多。公司去年第四季度的收入是8960万美元，同比增长48%，税前利润4930万美元，同比增长超过1500%。Opera最成功的地方是通过与运营商合作在新兴市场推广其移动浏览器，通过这种方式增加了数百万用户和大量收入。它的移动浏览器Opera Mini最重要的市场是俄罗斯， Opera全世界的移动用户高达2.7亿。Opera Mini一项对移动用户很有用的功能是压缩HTML数据，Opera表示接下来的重点将是增加视频压缩能力。Boilesen称，切换到Blink后的一大好处是绝大多数网站都能在Opera正常展示了，因为Opera使用的是和Google浏览器相同的引擎，而以前由于不被重视缺乏测试经常会出现兼容性问题，影响用户体验。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

IEEE Spectrum采访了前《连线》主编Chris Anderson和他的无人机创业公司3D Robotics。亚马逊、FedEx等巨头都公开谈论了他们的无人机快递计划，而Anderson对此态度谨慎，他曾说，无人机在人头顶上飞，最大的问题是隐私而不仅仅是监管。3D Robotics的商业模式是基于开源硬件和软件，这里没有秘密，该公司也没有申请任何专利。2011年，北京大学的一位博士生翻译了3D Robotics的无人机手册，帮助中国无人机爱好者购买中国产的3D Robotics无人机克隆。Anderson说他一开始很愤怒，随后意识到开源软件和硬件欢迎克隆，最后他在网站上链接了这位博士的译稿。Anderson认为，民用无人机的第一大市场是农业。国际无人机系统协会的总顾问Ben Gielow也持有同样看法，认为，早期的商用无人机八成将应用于农业，一成是公共安全，还有一成是测绘和野生动物保护。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

中国科学家在云南昆明成功培育了多只被去除特定基因的猴子，实现了基因靶向修饰技术在灵长类动物身上的应用。研究人员从2013年初开始，对食蟹猴和猕猴的几个特定基因进行了敲除，成功进行体外受精、胚胎移植等一系列实验，2013年底成功培育出全球首例经过基因靶向修饰的小猴，研究报告发表在《细胞》和《细胞干细胞》期刊上。试验主要对灵长类动物的四个特定基因进行了敲除，其中三个基因分别涉及性别控制、免疫系统、代谢系统，有10只食蟹猴在胚胎移植后成功受孕。另外一个基因涉及神经发育，对猕猴、食蟹猴都进行了试验，也十分成功，有6只猴子成功受孕，多数怀孕失败，其中一只雌猴五个月后诞生了一只小猴。目前最早诞生的猴子仍然存活。基因修改技术一向存在伦理方面的争议，尤其是应用于人类身上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

由于对司机和乘客采用双向补贴，打车软件近期风靡于全国各大城市。打车软件的流行对传统出租车市场造成冲击，引发社会热议。上海交通运输和港口管理局昨晚发布消息，对打车软件进入出租车行业，将进一步依法合规管理，禁止出租车在早晚高峰时段使用打车软件。上海交港局表示，打车软件改变了传统的出租汽车预约调度模式，提高了出租汽车运营效率，但其市场营销手段、价外加价功能，以及对司机注册登记把关不严等问题，已不同程度影响了出租汽车行业公平、公正的运营市场秩序。 从3月1日开始，在高峰时段新增运力配置方案出台前，暂行实施每天7点30分到9点30分，下午4点30分到6点30分的早晚高峰时段，出租汽车严禁使用打车软件提供约车服务措施，以缓解高峰时段打车难。上海交港局2月27日将再度约谈"嘀嘀打车"和"快的打车"，重申必须在2月底前明确态度，将打车软件与出租汽车公司电调平台开展合作，将打车软件约车业务纳入电调业务统计范围，承接打车软件约车业务车辆顶灯显示"电调"，并确保行车安全，对已载客运营车辆，屏蔽发送业务信息。中国的出租车公司全是国营的，都是受国家调控。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

P2P僵尸网络



极客 写道 "据Fortinet研究，业界排名前五的僵尸程序分别是：ZeroAccess、Jeefo、Smoke、Mariposa和Grum（Tedroo）。其中，Grum网络在2011年7月被打掉了，Mariposa的主C&C服务器在几年前也被拿下。2012年12月下旬，微软联合欧美执法部门断掉了ZeroAccess。当人们正大肆宣传ZeroAccess被攻克的消息，MalwareTech 博主认为（中文）是时候介绍一下P2P僵尸网络(botnets)了。包括僵尸网络的工作原理和应对方法。P2P僵尸网络的主机之间可以互相通信，不需要一个中心的指令服务器。"

亚马逊是一家全球性的超市，就像沃尔玛；它还是一家硬件制造商，就像苹果；是基础设施服务商，就像爱迪生联合电力公司；是视频分销商，就像Netflix；是图书出版商，就像兰登书屋；是影视工作室，就像派拉蒙；是文学杂志，就像《巴黎评论》；是网上食杂商，就像FreshDirect；它还提供包裹快递服务，就像UPS。它的老板还拥有一家大型报纸《华盛顿邮报》。《纽约客》的作者George Packer发表了一篇长文（中文翻译），主要从出版商的角度，谈论亚马逊的破坏性创新对出版业的影响，以及对出版商的"压榨"。文章称，如果出版商不缴纳推广费，那么亚马逊的推荐算法就可能会不显示该出版商旗下的书籍。六大出版商在2010年选择与苹果合作，获得定价权，尝试电子书销售的代理模式而不是亚马逊所用的批发模式，试图提高电子书的价格。亚马逊投诉到了联邦贸易委员会。2012年，法院裁决苹果和出版商败诉，虽然苹果声称抬高价格促进了竞争。作者认为，法庭的判决反映了自由主义者和保守主义者所共有的一种法律思潮，站在消费者而非生产者的角度来看待垄断：只要能降低价格，哪怕因此牺牲了竞争也在所不惜。法官的判决对于自称"地球上最为用户至上的公司"的亚马逊来说，简直是甜言蜜语。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

三星在移动世界大会上展示了搭载Tizen OS的手机原型。Tizen是基于Linux的操作系统，主要由三星和英特尔开发。作为最大的Android手机制造商，三星如何在Android和Tizen之间作出选择正日益引起人们的兴趣：三星可以完全控制Tizen，而Android则受制于Google。从表面看， Tizen OS完全像一个Android克隆，除了不能运行Android应用外。和Android一样，Tizen有一个应用程序清单，home页，下拉式通知面板和widget。和Android中的一样，widget和图标实际上是一样的，只是可以改变大小。类似其它新兴的移动操作系统，Tizen面临的一大问题是缺乏应用程序，三星表示Tizen支持C++原生或HTML5应用，已说服一些公司开发Tizen应用，如Gameloft就开发了一个Tizen版的《狂野飙车8》。三星已表示将会在今年内发布Tizen手机。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

上周，《魔兽世界》商店短暂列出了一个叫"Level 90 character boost"的虚拟物品，顾名思义这个商品可以将玩家的角色提升到90级，代价是60美元，引发了广泛争议。暴雪雇员昨天证实，它确实计划向玩家出售90级角色升级包，并为60美元的价格辩护说，他们不想贬低玩家等级提升成就的价值——如果不花钱，角色升级到90级需要数十小时。暴雪的 Ion Hazzikostas说，如果他们的目的是尽可能多的出售这个物品，那么他们可以将价格减半或更低，比如说10美元，但提升等级需要时间和精力，暴雪不愿意贬低这一过程的价值。暴雪去年底宣布了最新的资料片《德拉诺之霸（Warlords of Draenor）》，资料片将玩家等级从90级提升到100级。暴雪最初说是玩家可以免费创建90级角色以体验新的内容，但如今暴雪却说花60美元让玩家有动力体验新的内容。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

根据彭博新能源金融（Bloomberg New Energy Finance）的数据，2013年中国在智能电网上投资为43亿美元，首次超过了美国，美国只投入36亿美元，市场呈现萎缩。中国正在安装6千万个智能电表，智能电表费用占了大部分的支出。欧洲国家如英国也在推广智能电表和燃气表。中国市场和外国市场的不同之处是，它的绝大多数电网都控制在国家电网手中，推广智能电网的速度要比一个分散的控制不严的市场快得多。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

越来越多的恶意程序利用Tor来隐藏指令控制服务器的IP位置，Tor匿名服务被称为暗网，利用多个中继节点隐藏IP地址的原始位置。但这些恶意程序多数是以桌面为目标。现在，卡巴斯基报告了第一个以Android为目标的Tor木马。攻击者修改了Tor客户端Orbot，利用 Tor网络的.onion代理服务器隐藏指令控制服务器的位置。被称为backdoor.AndroidOS.Torec.的恶意程序可接受命令执行一系列任务，包括拦截传入传出的信息，向指令控制服务器发送设备信息，包括型号、操作系统版本、国家、应用安装列表和IMEI，可用于远程执行代码。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

Stephen Wolfram演示了基于知识的新语言Wolfram Language，表示他的团队正接近发布语言的第一个正式版本。Wolfram语言自称结合了广泛的编程样式，使用了符号编程的独特概念，将编程的灵活性提升了一个新的高度。从演示中看，Wolfram语言实际上就是Mathematica，或者是用Mathematica描述的语言。暂时不清楚Wolfram语言是否会开源或者允许免费使用。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

他自负、行事诡秘、偏执、嫉妒、爱与年轻女性调情，经常说一些性段子。这些看法不是来自于他的一位敌人，而是一位同情他的朋友。WikiLeaks创始人Julian Assange的上述描述来自于他传记的捉刀人Andrew O'Hagan。O'Hagan花了几个月时间与Assange在一起，为传记收集材料。O'Hagan说，Assange宁愿花几个小时搜索自己的名字，也不愿意为他的传记说几句话。Assange的行为更像是一位任性的暴君，对自我宣传而不是改变世界感兴趣。他经常会嘲笑自己的朋友，对于厄瓜多尔英国使馆向其提供外交庇护，Assange称对方的行为疯狂而可笑。甚至Assange的女友、WikiLeaks研究员Sarah Harrison也日益对其行为而感到灰心，她与其他男性说话就会惹恼他，而他自己在与女性交谈时却并不自觉。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

Mozilla试图在多核和移动时代重新发明浏览器。它正与三星合作开发一个新的浏览器布局引擎Servo，设计不受任何旧有代码的限制，打破现代浏览器的性能枷锁。Servo使用Mozilla的新语言Rust开发，Rust是一种注重安全、性能和并发性的编程语言，Mozilla预计将会在年内发布1.0版。Mozilla平台工程师Josh Matthews指出，基本上今天所有的浏览器都是在2000年前设计的，当时的硬件情况与今天大为不同，硬件通常只有一个CPU核心，频率也很低，可用内存非常少。Servo设计能利用手机和平板的多核处理器执行并发任务。现代浏览器解析HTML网页是按照顺序计算布局，渲染内容和执行脚本，Servo能平行的执行这些任务。在Rust语言中，每个任务都是分离的，彼此不共享内存，使用异步的消息传递互相通信。Servo的布局、渲染和脚本任务都是分离的，以各自的速度运行。Servo正由Mozilla的一个五人工程师团队和三星的一个研究团队共同开发，Mozilla希望能在年底构建出一个相对可用的版本。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

Ars采访了前往美国寻找经济和技术帮助的自由朝鲜战士领导人朴相鹤。多年来，朴相鹤的组织一直通过空飘气球的方式反击平壤。气球携带了U盘——其中储存了维基百科档案，流行电视剧的DVD，以及反政府传单和美元。该组织声称最近几年已经送出了5200万传单，但由于缺乏来自朝鲜的第一手信息，因此不知道传单和气球究竟产生了什么影响。朴相鹤说，他们正寻找实用的方法改进宣传气球的效力，包括改进气球的GPS定位功能，使得他们能精确掌握气球着陆的位置。他的组织还计划组织一个 hackathon活动，帮助改进气球设计和降低成本。朴相鹤是在1999年与家人一道经过中国叛逃到韩国，他的一个叔叔因此在朝鲜被打死。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

位于日本的比特币交易平台MtGox昨天突然暂停交易和关闭网站，引发了大量传言和谴责。其中一条传言称MtGox过去几年被悄悄偷走了74.4万比特币。六大比特币服务商为此联合发表声明，谴责Mt Gox"悲剧性地背弃了人们的信任"，承诺将恢复人们对比特币的信心。Blockchain.info的CEO Nicolas Cary说，"几周以来，Mt Gox的传闻一直在缓慢地趋于明朗。这一最新动态看来是他们动荡历史上的最后一个悲惨章节。"乔治城大学经济学教授Jim Angel表示，比特币就好像电子书，其好坏状况有赖于支持其使用的基础设施。"鉴于比特币的基础设施完全没有监管、技术也是新兴的，出现眼下这种问题应该在意料之中。"MtGox已经在网站首页发表简短声明，声称关闭交易是为了保护网站和用户，除此之外没有做出进一步解释。《华尔街日报》援引知情人士的消息报道，MtGox已经收到纽约联邦检察机构发出的一张传票。路透社报道称，日本官员周三表示他们正着手对MtGox的突然关闭展开调查。内阁官房长官菅义伟说，相关金融监管机构、警方、财务省等正在收集信息。MtGox CEO Mark Karpeles在一封电子邮件中表示，因为牵涉到其它方他目前不能透露太多信息。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

位于法国的国际热核聚变实验反应堆项目（ITER）已经多次受到管理混乱的指责，最新的审议报告发现项目的领导、管理和治理都存在严重问题。报告是如此具有破坏力，以至于2月13日特别会议接受报告结论和建议后，管理ITER项目的理事会只允许少数高级管理人员和理事会成员阅读报告。理事会主席、咨询公司CH2M HILL的核工程师Bob Iotti 说，他们担心如果审议报告泄漏给不知道ITER协议的人，报告可能会被解释为是一次巨大的失败，这不是评估报告的目的。ITER是中国、欧盟、印度、日本、韩国、俄罗斯和美国合作开发的热核聚变实验反应堆计划，目前正在法国的Cadarache建造，项目完成日期已经从原计划的2016年延期到了2020年，估计成本也增加了两倍，至少需要投入160亿欧元.This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

一个国际团队使用日常材料如鱼线和缝线，创造出至今最强的人造肌肉。研究报告发表在上周的《科学》期刊上。研究人员将几百微米的纤维扭曲和绕成圈状，一旦纤维形成紧密的线圈，科学家再利用热处理方法防止纤维伸展开来，最后他们就创造出了一种具有肌肉特性的材料，能收缩伸展弯曲。相比之下，生物肌肉只能收缩长度的20%，而人造肌肉能超过50%，并能提起100倍于相同长度人类肌肉能处理的重量。每公斤人造肌肉能产生5千瓦的机械功，输出效率类似喷气引擎。研究人员认为，这项研究可应用于医疗设备、假肢和服装等领域。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

安全公司Bromium Labs的研究人员开发出能完全绕过微软安全工具EMET（Enhanced Mitigation Experience Toolkit的缩写）的攻击代码，此举意味着黑客也能利用同样的漏洞绕过安全保护系统悄悄安装恶意程序。Bromium Labs发布了白皮书（PDF），其官方博客指出，运行在用户空间的安全工具如EMET都具有局限性，都有可能会被恶意程序绕过，因为它们并不具有更高级的保护。Bromium Labs在公开其研究前已事先通知了微软，目前EMET的最新版本是4.1，微软将在今年发布EMET 5，有可能会修复问题，但研究人员表示他们利用的是用户空间安全工具共有的局限性，可能并不容易修正。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

新浪准备分拆微博业务，赴美上市。但面临腾讯微信和政府收紧言论控制两大威胁的微博，其用户增长速度已经创下了新低，新浪选择分拆和上市的时机令人感到奇怪，分析师推测，新浪此举是准备出售微博，因为独立的微博是一个有吸引力的收购目标，阿里巴巴已持有18%的新浪微博股份。据新浪CEO曹国伟提供的数据，微博日均活跃用户从去年9月的5900万增至了去年12月的 6140万。CNNIC最新发布的报告称微博用户数量下降了2000万，新浪对此声称是其它微博平台人数减少。微博用户数量减少的一个原因被认为与政府加大言论管制有关，北京一直担心网民使用微博发泄对政府渎职的不满，或利用微博组织反腐败或抗议环境污染的游行示威，新浪为此雇用了小秘书删除相关帖子。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

路透社报道，巴西和欧洲周一宣布将铺设一条连接葡萄牙首都里斯本和巴西港口城市福塔雷萨的海底光缆，以减少对美国的依赖。NSA此前被曝光拦截了巴西总统的通信，入侵了巴西国家石油的计算机网络，监视了巴西居民在社交网站上的活动。巴西总统 Dilma Rousseff说，这项价值1.85亿美元的海底光缆项目对于捍卫互联网的中立性极为重要，"我们必须尊重隐私、人权和国家主权。"她声称互联网是一块言论自由表达的民主之地。巴西需要依赖美国的海底光缆将通信传送到欧洲。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

用数据指标测量我们如何工作的大数据分析公司正如雨后春笋般大量涌现。经济学人信息社近期公布的一项研究表明，在世界各地的人力资源部门中，声称比三年前更多使用数据分析的比例超过了二分之一。但所幸很多雇员仍然一无所知，一些在他们看来或许是私人的信息正如何被他们的经理分析研究。其中一家叫Steelcase的公司在办公家具以及办公楼中置入感应器，以观察员工之间如何互动。David Lathrop是Steelcase的研究和战略主管。他表示，目前感应器的价格是如此低廉，以至于他们可以将感应器放在"几乎任何地方"。他指出，员工可以通过跟踪自身表现而受益。并非每个人都相信，越来越多地运用技术手段来监控员工的工作效率是一种无可争议的进步。哈佛商学院教授和研究主管Teresa Amabile指出，技术监控既能带来"非常积极"的效果，也能造成"非常负面"的影响，具体情况取决于企业现有的办公室文化。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

政府治理空气污染的一个关键举措是改革中国河北省臃肿的钢铁产业，但整顿钢铁产业多数是通过市场而不是政府来完成的。河北是中国的钢铁产业大省，全国10个污染最严重的城市有七个在河北。经常蔓延至北京的雾霾使公众日渐不满，去年中央政府召集河北省的领导在北京多次开会，敦促他们制定计划削减钢铁产能。最终达成的协议是：目标到2020年削减8600万吨，约占当前产能的35%。自上周以来，严重雾霾再次笼罩华北大部分地区，中央政府再次向河北等地区派出巡视组检查当地政府如何应对。专业人士表示，由于需求放缓、钢价大跌以及流动性危机，许多工厂已经濒临破产， "他们只是关闭已经倒闭的钢厂"，"利润低薄，炼厂都在亏钱——这与环保措施毫无关系，完全是经济问题。"

路透社报道（中文），专业社交网站LinkedIn周一推出中文版，加强在中国这一全球用户数量最大互联网市场的扩张，不过该公司也承认，将监管网站上的用户言论。LinkedIn CEO Jeff Weiner周一在博客中承认，该公司将不得不对用户张帖的一些内容进行审查，以遵守中国的法规。但Weiner表示，向中国用户提供在线服务，好处超过上述那些忧虑。 "在中国提供服务会带来难题，但我们坚决推进显然是正确决定，"Weiner称。国外互联网企业在中国运营面临很多困难。北京从互联网上审查敏感词，屏蔽了两大社交媒体Facebook 和Twitter。LinkedIn关于利大于弊的说法与Google在2006年为实行自我审查的中文版进行的辩护如出一辙。四年之后，Google搜索退出了中国大陆。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

科学家称，月球去年遭遇了一颗太空岩石的撞击，创造了有记录以来最亮的月面爆炸事件。撞击发生在2013年9月11日GMT时间下午8:07，产生的亮度堪比北极星，也就是说如果天气条件许可的话，任何在这个时候凝视月球的地球人都可能会看见这次爆炸。太空岩石以61,000 km/h的速度撞击月面，创造了一个直径40米的陨石坑，释放的能量相当于15吨TNT。科学家估计太空岩石质量约400 kg，直径0.6米到1.4米。如果同样大小的岩石撞击地球，它可能会在天空创造一个火流星，但不太可能会威胁地面上的人。

中国与全球化研究中心发出警告说，误入"野鸡大学"已经成为海外留学一大隐患。该机构援引美国大学统计的数据称，美国"野鸡大学"泛滥成灾，而中国成为其最大的受害国，美国的"野鸡大学"每年的学位证书95%给了中国人。"野鸡大学"(Diploma Mill)也称"学历工厂"或"学店"，办学以营利为目的。 许多中国人认为，大学文凭是获得稳定和收入不菲工作的通行证。中国与全球化研究中心分析认为，野鸡大学在内地之所以有巨大的市场，首要原因是学历不能承受之重。其次，扭曲的用人标准在作祟。该中心建议，中国政府应提早考虑成立有关的多边合作机制，积极推动建立一个能够规范国际留学市场的高效调节管理机制。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

电影胶片可以储存100年甚至更久，只要储藏室不要太潮湿也不要太干燥，保存下来的20世纪前10年制作的电影，我们今天仍然能欣赏。胶片成本不高，从胶片中获取信息的方法也很简单。但数字电影的兴起改变了这一切，今天的大多数电影不是储存在胶片上，而是以比特形式记录保存。数字电影的质量不比胶片电影差，但数字电影媒介的储存时间却比不上胶片。储存媒介的受损，文件格式、软硬件变化都影响着数字电影的可访问性。如果你用智能手机记录视频用照相机拍摄照片，那么每隔几年，你都必须将所有的数字内容转移到最新的储存媒介上，否则你将有丢失数据的风险。今天的数字储存技术无法保证能将数据保留给后代。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

Synthetic version of heparin created for use in kidney patients
http://feeds.sciencedaily.com/~r/sciencedaily/~3/F45DRnuzm6o/140223215103.htm
Feb 24th 2014, 02:51

Researchers at Rensselaer Polytechnic Institute and the University of North Carolina at Chapel Hill (UNC) have created a synthetic form of low-molecular-weight heparin that can be reversed in cases of overdose and would be safer for patients with poor kidney function.
"We took this drug and not only made it cost effectively, but we've also improved the properties of the drug," said Robert Linhardt, the Ann and John H. Broadbent Jr. '59 Senior Constellation Professor of Biocatalysis and Metabolic Engineering, a member of the Rensselaer Center for Biotechnology and Interdisciplinary Studies (CBIS), and one of the inventors of the new drug. "The synthetic version that we've made is reversible, it can be used in renal patients, and it doesn't come from animals, which is a critical advance in safety."
Heparin is an anticoagulant, and is most commonly extracted from pig intestines in two forms: unfractionated heparin, which is commonly used in procedures such as dialysis, and a more-refined low-molecular-weight (LMW) heparin, which is used around the world for preventing dangerous blood clots. A team led by Linhardt and Jian Liu, a professor in the UNC Eshelman School of Pharmacy, created a synthetic version of LMW heparin for which there is an existing antidote. Their creation is described in an article published online February 23 in the journal Nature Chemical Biology.
Linhardt and Liu used a chemo-enzymatic process to synthesize the drug, an approach they developed in research on a simpler anticoagulant drug published in Science in October 2011. Synthesizing LMW heparin allowed them to make many improvements on the animal-derived form of the drug currently available. Linhardt's research supports the Rensselaer School of Science interdisciplinary theme of biomedical science and applications, and is part of a research focus on biocatalysis and metabolic engineering within CBIS. His research on LMW heparin was funded by the National Institutes of Health.
Up to 5 percent of patients receiving heparin experience some form of uncontrolled bleeding. Patients receiving unfractionated heparin are in less danger because there is an existing Federal Drug Administration-approved antidote (protamine) available. Protamine is not as effective in reversing naturally derived LMW heparin, so Linhardt and Liu engineered their drug's molecular structure so that protamine is able to deactivate it.
Naturally produced LMW heparin is cleared from the body by the kidneys, which can make it unsuitable for patients with a weakened renal system, a relatively common condition among patients requiring anticoagulation. Linhardt and Liu made additional changes allowing their drug to bind to receptors that clear it through the liver.
LMW heparin makes up more than half the U.S. market for heparin. Linhardt and Liu said the new version they created is a safe, economically viable alternative to the existing animal-derived supply. But the new drug would require FDA approval, and would probably also undergo alteration on the path to market.
"This is a discovery target. The process that we've used to make it is clearly capable of making the final product. But drug developers would probably want to change some details," Linhardt said. "We've advanced the method to make this drug. Now it's a question of looking at exactly what the new drug would be."
Heparin has been in use since the late 1930s. There are three main types of heparin: unfractionated heparin, the more highly processed low molecular weight heparin, and fondaparinux, a wholly synthetic ultra-low molecular weight heparin.
Heparin prevents blood clots from forming and is most often used during and after such procedures as kidney dialysis, heart bypass surgery, stent implantation, and knee and hip replacement. Its side effects can include uncontrolled bleeding and thrombocytopenia (too few platelets in the blood). The worldwide sales of heparin are estimated at $4 billion annually.
The natural form of the drug was in the spotlight in spring 2008 when more than 80 people died and hundreds of others suffered adverse reactions to it, leading to recalls of heparin in countries around the world. Authorities linked the problems to a contaminant in raw natural heparin from China.
"Whenever you mix the food chain and the drug chain together, you end up with potential for disaster. Whether it comes from contamination, adulteration, impurities like viruses or prions -- any of those possibilities are much more likely when you make something in an uncontrolled environment," said Linhardt. "This is a drug that millions of people rely upon, and it's important to develop a safe, synthetic alternative to the current supply chain."

United Kingdom urgently needs a green economic strategy: Report
http://feeds.sciencedaily.com/~r/sciencedaily/~3/yNJe_JJjRuo/140223215136.htm
Feb 24th 2014, 02:51

The UK urgently needs a green economic strategy to move towards low-carbon prosperity, resource security and environmental quality, says a new report published today by UCL's Green Economy Policy Commission.
The Commission -- drawn from a range of academic disciplines across UCL -- argues that the UK's current situation of climate instability and increasing resource constraints mean that decisive action is urgently needed by the UK government to green the economy.
Greening the Recovery argues that there is a window of opportunity for policies that acknowledge future resource constraints and deliver more sustainable growth. Such policies will address fundamental structural weaknesses and achieve a sounder economic recovery. The report provides a comprehensive overview of the key elements of a green economy. It emphasises that a green economy is not about niche sectors, but about the whole economy. As well as identifying the major challenges for the UK, it makes a number of specific recommendations for policies to address these.
Professor Paul Ekins, Chair of the UCL Green Economy Policy Commission, said: "The recent floods and appalling weather conditions should remind policy makers of the dangers and risks of failing to take action to mitigate environmental threats. The report's recommendations are intended to enhance the UK's resource and environmental security, and contribute to the global imperative to reduce greenhouse gas emissions.
"In addition, the report suggests that, by taking action to green the economy, the UK can address existing weaknesses in innovation and infrastructure investment, positioning itself to be an international leader in eco-innovation, and building a resilient economy with the conditions for sustained and long-term growth. We hope that policymakers and politicians will recognise the urgent need to act and will show the policy leadership that the UK needs to commit to a greener economy."
Greening the Recovery identifies innovation, infrastructure and information as the key areas in which policies are needed to support a green economy, in addition to arguing for environmental fiscal reform and specific policies at UK and EU level to support resource efficiency.
The report's keynote findings are:
There is currently a window of opportunity to put the UK economy decisively on a trajectory towards low-carbon prosperity, resource security and environmental quality: resource costs are low, the added benefits of stimulating directed investment are large, and structural reform is required in any case;
A green economy strategy can strengthen the UK economy by overcoming key structural weaknesses, particularly under-investment in infrastructure and under-performance in innovation. A credible, long-term strategy, supported by environmental tax reform, can thus deliver a more durable recovery while contributing to climate stability, resource security and better environmental quality.
Government should take a more proactive, strategic approach to driving green innovation. A green industrial strategy can help to address existing weaknesses in the UK innovation system and secure comparative advantage in key sectors and areas of technology -- the UK still has the opportunity to be a leader in many of these areas, but other countries are already seizing the initiative;
Government should adopt a clearer approach to prioritisation of key infrastructure projects, and ensure that infrastructure investments are compatible with long-term green economy objectives. Going beyond the undifferentiated infrastructure list in the UK Infrastructure Plan, the Government needs to identify what green infrastructure investments are required and prioritise these accordingly in order to ensure policy clarity and credibility;
A new information infrastructure is required to enable a greener economy. Our national accounting practices and corporate reporting rules were developed at a time when the economic and social importance of environmental constraints was less well recognised than it is today. Government should introduce new efforts to develop comprehensive natural capital and material flow accounts.
