1. Hundreds of genes spring to life after you die - and they keep functioning for up to four days. Together with an unexplained case in March that recorded brain activity in a corpse up to 10 minutes after death, we#39;re starting to realise that death as we know it still retains some strange signs of life.在你死后,数以百计的基因会突然活跃起来,而且还会继续活动长达4天。3月份的一个实例表明,在人死后,尸体的大脑还会活动长达10分钟,连同这个无法解释的实例,我们开始意识到我们所了解的死亡依然保有一些奇怪的生命迹象。2. Livers grow by almost half during waking hours. New research suggests that livers have the capacity to grow by almost 50 percent during the day, before shrinking back to their original size at night. They are the only organ we know of that oscillate this way.在你醒着的时候,肝可以扩大将近一半。新的研究指出,在白天的时候,肝有能力扩大近50%,然后在夜间则会缩回到原始尺寸。肝是我们所知道到的唯一一个可以这样变化的器官。3. The root cause of eczema has finally been identified. Scientists have tracked down a series of proteins and molecular pathways that lead to this insufferable skin problem, revealing that the protein filaggrin isn#39;t the sole culprit we thought it was.湿疹的根本原因最终得到确认。科学家查到了一系列蛋白质和分子引起这种令人难以忍受的皮肤问题的途径,并指出丝聚合蛋白并非唯一的祸首,而我们过去却是这样认为的。4. We were wrong - the testes are connected to the immune system after all. Researchers have discovered a ;very small door; that allows the testes to send one-way signals to the immune system, and it could explain why some men struggle with infertility, and why certain cancer vaccines keep failing.我们错了——最终睾丸还是与免疫系统有关联的。研究人员发现了“一扇非常小的门”使睾丸可以向免疫系统发送单向信号,这解释了为什么一些男性会被不症所困扰,也解释了某些癌症疫苗一直失败的原因。5. The causes of hair loss and greying are linked, and for the first time, scientists have identified the cells responsible.脱发和头发变白的原因是相关的,科学家首次确认了对此负有责任的细胞。6. A brand new human organ has been classified. Researchers have given the nod to the mesentery - an organ that#39;s been hiding in plain sight in our digestive system this whole time. But that#39;s only half the story, because we#39;re still not sure exactly what it does.一种全新的器官被归类了。研究人员同意为肠系膜归类,这种器官显然一直隐藏在我们的消化系统中。但这只是其中的一方面,因为我们还不确定它到底是什么。7. An unexpected new lung function has been found. Researchers have found that lungs don#39;t just facilitate respiration - they also play a key role in blood production, with the ability to produce more than 10 million platelets (tiny blood cells) per hour. That equates to the majority of platelets in circulation at any given moment.肺的一项意外功能被发现了。研究人员发现肺不仅仅能促进呼吸作用,在造血方面也起关键作用,肺每小时能制造1000多万血小板(微小的血细胞),这相当于任何特定时刻循环中的血小板的大多数。8. Your appendix might not be a useless evolutionary byproduct after all. Unlike your wisdom teeth, your appendix might actually be serving an important biological function - and one that our species isn#39;t y to give up just yet.你的阑尾终究可能不是一个无用的进化副产物。你的阑尾不像智齿那样,事实上它可能发挥着重要的生物学功能,恰好现在人类还没准备好放弃阑尾的这种功能。9. The brain literally starts eating itself when it doesn#39;t get enough sleep. Chronic sleep deprivation causes the #39;clearing#39; process that usually happens when we sleep to kick into hyperdrive, prompting the brain to clear a huge amount of neurons and synaptic connections away.当大脑没有得到充分休眠时,它确实就开始自噬了。在我们睡觉的时候,“清除”程序通常就会启动,但长期缺乏睡眠会使该程序处于高速运转状态,促使大脑清除大量神经元连接和突触连接。10. Neuroscientists have discovered a whole new role for the brain#39;s cerebellum. It#39;s long been assumed that the cerebellum functions largely outside the realm of conscious awareness, coordinating basic physical activities like standing and breathing, but it could actually play a key role in shaping human behaviour.神经系统科学家发现了小脑的一项全新功能。长期以来人们一直认为小脑基本上与意识直觉等活动无关,它的主要作用是协调站立、呼吸等基本的身体活动,然而,实际上小脑在影响人类行为上也发挥着重要作用。11. Our gut bacteria are messing with us in ways we could never have imagined. New research has revealed that neurodegenerative diseases like Parkinson#39;s might actually start out in the gut, rather than the brain, and there#39;s mounting evidence that the human microbiome could be to blame for chronic fatigue syndrome. With gut bacteria showing signs of controlling our appetite, changing our brain structure, and triggering brain lesions that could lead to strokes, our tiny passengers are a force to be reckoned with.肠道细菌正以我们想像不到的方式干扰着我们。新的研究指出,像帕金森综合症等神经退行性疾病实际上可能始于肠道,而不是大脑。越来越多的据显示,慢性疲劳综合征可能要归咎于人体内的微生物群系。随着肠道细菌显示出控制食欲以及改变大脑结构的迹象,而且有引起大脑损伤而导致中风的表现,我们的这个小过客(肠道细菌)有着不容忽视的力量。 /201706/515004

Yes, we know. Our smartphone batteries are bad because they barely last a day. But it#39;s partially our fault because we#39;ve been charging them wrong this whole time.是的,我们都知道,现在我们的智能手机的电池越来越不耐用,顶多够用一天。但出现这种情况很有可能是我们自己造成的,因为一直以来我们的充电方式都不对。Many of us have an ingrained notion that charging our smartphones in small bursts will cause long-term damage to their batteries, and that it#39;s better to charge them when they#39;re close to dead.很多人都有根深蒂固的观念,多次短时间充电会有损电池的长期使用寿命,还认为电池完全用完了再充电会比较好。But we couldn#39;t be more wrong.但实际上,我们大错特错。If fact, a site from battery company Cadex, called Battery University, details how the lithium-ion batteries in our smartphones are sensitive to their own versions of ;stress.; And, like for humans, extended stress could be damaging your smartphone battery#39;s long-term lifespan.电池公司Cadex旗下网站Battery University详细介绍了智能手机中的锂电池对不同程度电压的反应。实际上,电池也跟人一样,额外的压力会减少电池的使用寿命。If you want to keep your smartphone battery in top condition and go about your day without worrying about battery life, you need to change a few things.如果想让自己的手机电池处于最佳使用状态,不用担心电池的使用寿命,那你需要改变几点做法。Don#39;t keep it plugged in when it#39;s fully charged.电池充满后拔掉插头。According to Battery University, leaving your phone plugged in when it#39;s fully charged, like you might overnight, is bad for the battery in the long run.根据Battery University的说法,电池充满电后不拔插头继续充电,比如有些人可能充一整夜,这样对电池的使用寿命影响很大。Once your smartphone has reached 100% charge, it gets ;trickle charges; to keep it at 100% while plugged in. It keeps the battery in a high-stress, high-tension state, which wears down the chemistry within.手机一旦处于100%的充满状态,如果继续充,手机会不停的连续补充充电。那么电池就一直处于高电压的状态,会损害电池内部的化学物质。Battery University goes into a bunch of scientific detail explaining why, but it also sums it up nicely: ;When fully charged, remove the battery; from its charging device. This is like relaxing the muscles after strenuous exercise.; You too would be pretty miserable if you worked out nonstop for hours and hours.Battery University详细的介绍了其科学原理并将其形象的总结为:;电池充满电后断开电源线,就像剧烈运动完后放松肌肉一样。;如果你连着好几个小时不间断的锻炼那身体肯定受不了。In fact, try not to charge it to 100 percent. According to Battery University, ;Li-ion does not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery; and wears it away in the long run.实际上,尽量不要将电池充到百分之百。按照Battery University的说法,锂电池不需要完全充满电,这样对电池也不好。实际上,电池处于未充满状态反而比较好,因为高电压会对电池造成压力,长此以往会损害电池的使用。Plug in your phone whenever you can尽可能的多充电It turns out that the batteries in our smartphones are much happier if you charge them occasionally throughout the day instead of plugging them in for a big charging session when they#39;re empty.事实明,同把电量用完后长时间一直充电相比,不时的充电会更有利于智能手机中锂电池的使用。Charging your phone when it loses 10% of its charge would be the best-case scenario, according to Battery University. Obviously, that#39;s not practical for most people, so just plug in your smartphone whenever you can. It#39;s fine to plug and unplug it multiple times a day. Not only does this keep your smartphone#39;s battery performing optimally for longer, but it also keeps it topped up throughout the day.按照Battery University的建议,手机每用掉10%的电量就充电是最好的方式,充电效率最高。但是显然,对大部分人来说这不现实,所以尽可能的在能充电的时候就充电,一天多充几次。这样不仅仅能使手机的电池使用的更久,而且电量一直都是满的。Keep it cool保持电池凉爽Smartphone batteries are so sensitive to heat that Apple itself suggests you remove certain cases that insulate heat from your iPhone when you charge it. ;If you notice that your device gets hot when you charge it, take it out of its case first.; If you#39;re out in the hot sun, keep your phone covered. It#39;ll protect your battery#39;s health.智能手机的电池对发热很敏感,苹果公司建议手机充电的时候放在易散热的地方。;如果你发现手机在充电的时候有发热的现象,就先拔掉电源线。;如果在太阳下,注意不要让手机暴晒在太阳下。这样可以延长电池的使用寿命。 /201607/456530

;Could you hear me?; Stephen Hawking asked in his iconic computer-synthesized voice, getting a cheerful ;yes; from hundreds of people in a speech hall at the Hong Kong Science Park.“你们能听到我说话吗?”当史蒂芬·霍金标志性的电脑合成嗓音传来,香港科技园演讲大厅的上百号人兴奋高呼:“可以”。;I can hear you, too,; in seconds he replied, this time triggering from the audience even more exclamations: ;Wow, cool;!“我也可以听到你们!”几秒种后,霍金回应道,并引来了现场观众又一阵惊呼:“哇塞!这简直太酷了!”This dialogue appeared to be a face-to-face chat, but according to the organizer, Hawking was actually sitting in front of a green screen in his office in Cambridge, only having his image beamed to a transparent screen in the hall in Hong Kong and presented to the audience as a digital human hologram.这段对话看似是一场面对面式的闲聊,但是组织方表示,霍金事实上是坐在剑桥办公室的一块绿幕面前,他只是将自己的影像投射到香港科技展厅的透明屏幕之上,以数字全息图像的呈现方式与大家见面。In the over-one-hour speech, Hawking talked about his life experience and research progress, shared his views on topics from the beginning of time to Brexit, and encouraged the audience to tackle difficulties in life just as how he did.在接下来一个多小时的谈话中,霍金谈到了自己的生活经历以及研究进程,也对从时间起源到英国脱欧等各类话题分享了自己的见解,同时鼓励观众像他一样勇于克生活中的各种困难。The speech included a touching account of the world-famous physicist#39;s early life, as well as flashes of his sense of humor.这段演讲谈及了这位世界知名物理学家令人动容的早年经历,同时还有展现了霍金幽默感的片段。Talking about how he almost lost confidence in life after his was diagnosed with a motor-neuron disease but regained momentum for continuing his research after meeting his future wife, Hawking said: ;If I want to get married, I need to finish my Ph.D. and get a job.;当谈到自己得知因患上肌肉萎缩性侧索硬化症而失去对生活的信心、却又在遇见妻子后重燃希望继续从事学习研究时,霍金调侃道:“我要想结婚,就得先念完士,找个工作。”When referring to his bestselling book A Brief History of Time, he joked: ;I am sure you have all it from cover to cover, so I shall be asking questions later.;当提到自己的畅销之作《时间简史》时,霍金开玩笑般说道:“我相信你们都已经从头到尾读过这本书了,我觉得一会儿我应该提几个问题。”This virtually-delivered speech was realized thanks to the augmented reality holographic technology, or HumaGram, as called by the developer ARHT Media on its website.这场“实时对话”的圆满完成都要归功于现实增强全息人像技术,开发商增强现实全息影像技术(ARHT)公司在其官方网站上也将其称之为“HumaGram”,即交互性人体全息影像技术。ARHT Media President and CEO Paul Duffy said he hoped to use this technology to ;bring; more outstanding figures to Hong Kong and provide inspirations for citizens here.ARHT公司的总裁兼首席执行官保罗·达菲表示,他希望可以通过使用这项技术令香港接触更多的杰出人物,为当地人民提供灵感与启示。 /201704/501870

你“Google”过自己吗?Have you ever "Googled" youself?More Americans are Googling themselves — and many are checking out their friends, co-workers and romantic interests, too.In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher."Yes it's doubled, but it's still the case that there's a big chunk of Internet users who have never done this simple act of plugging their name with search engines," she said.Americans under 50 and those with more education and income were more likely to self-Google — in some cases because their jobs demand a certain online persona.Meanwhile, Pew found that 53 percent of adult Internet users admit to looking up information about someone else, celebrities excluded.Often, it's to find someone they've lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.In many cases, the search is innocuous, done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies and divorce proceedings. A similar number have searched for someone else's photo.Few Internet users say they Google themselves regularly — about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate.Pew also found that teens were more likely than adults to restrict who can see their profiles at an online hangout like Facebook or News Corp.'s MySpace. 如今,越来越多的美国人在Google上搜索自己,还有很多人通过Google查找朋友、同事或约会对象的信息。Pew互联网和美国生活项目在上周日发布的一份调查报告中称,47%的美国成年互联网用户通过Google或其它搜索引擎查找过有关自己的信息。这一比例比2002年的22%增长了一倍多,但Pew调查中心的高级研究员玛丽#8226;麦登认为增幅还不够大。她说:“在Google上搜索自己的网民比例确实翻了一番,但调查同时显示,目前仍有很多网民从未用搜索引擎搜索过自己的名字。”年龄在50岁以下的美国人以及受教育程度和收入较高的人在Google上搜索自己的几率更大,这是因为他们的工作有时需要在网上公开个人信息。此外,Pew调查中心发现,53%的成年网民承认自己曾在Google上查找过除名人以外的其他人的信息。在很多情况下,人们这样做只是为了寻找失去联系的人,但也有很多人通过Google查找朋友、亲戚和邻居的信息。男性和女性网民在Google上搜索自己的人数比例差不多,但女性更爱在网上搜索约会对象的信息。在很多情况下,在网上搜索别人纯粹是为了找到此人的联系方式。但有三分之一的人这样做是为了了解别人的公共纪录,如破产及离婚纪录等。另有相同比例的人曾搜索过别人的照片。多数网民并不经常在Google上搜索自己——约四分之三的人称,他们仅搜索过一两次。多数人认为他们搜索到的有关自己的信息是正确的。该调查还发现,与成年人相比,青少年更希望限制别人在Facebook或Myspace等社交网站查看自己的个人信息。 /200803/32072
