When news spread late last year that the Fermilab National AcceleratorLaboratoryin suburban Chicago was part of a project achieving quantum teleportation, it conjured up scenes from the classic science fiction franchise Star Trek in which the show's characters could beam from one location to another.
去年年底，当有消息传出芝加哥郊外的费米国家加速器实验室参与了一个实现量子隐形传态的项目时，这不禁让人联想到经典科幻系列《星际迷航》中的场景——剧中角色可以从一个地点瞬间传送到另一个地点。

That's not what we're doing here. What we're doing here actually is we're moving information without even physically moving the qubit that contains information.
这并非我们在这里的目的。我们在这里实际做的是，无需物理移动承载信息的量子比特，就能传输信息。

Fermilab scientist Panagiotis Spentzouris is one of the co-authors of a study documenting the advancement of sending or teleporting information or qubit, a unit of quantum computing code.
费米实验室的科学家Panagiotis Spentzouris是这项研究的合著者之一，该研究记录了发送或传送信息或量子比特（量子计算代码的单位）的进展。

Over 40 kilometers through fiber cables, it brings developers one step closer to building a sustainable and widely used quantum internet, which would allow a lot of information to be shared faster and more securely.
它通过光纤电缆跨越四十多公里，让开发者距离构建可持续且被广泛使用的量子互联网更近一步，这种量子互联网能够让大量信息以更快、更安全的方式共享。

Quantum communication has very appealing attributes. I mean, you cannot eavesdrop in a way that will not be detected.
量子通信具有非常吸引人的特性。你无法在不被发现的情况下进行窃听。

What we achieved here with the systems is that we have produced systems that they can continually operate and perform quantum measurements at all times as a system, not just as a single experiment.
我们借助这些系统所达成的成果是，我们制造出了能够持续运行并随时作为系统进行量子测量的系统，而不仅仅是单次实验。

Physicist Maria Spiropulu, based at the California Institute of Technology in Pasadena, California, says quantum teleportation could sustain networks that enhance GPS and speed up and amplify communication at great distances with spacecraft and probes, among many other possibilities.
位于加利福尼亚州帕萨迪纳市的加州理工学院的物理学家Maria Spiropulu表示，量子隐形传态可以维持能增强全球定位系统性能、加快并放大与远距离航天器及探测器通信的网络，还具备许多其他可能性。

While building a new quantum internet would revolutionize the way we share sensitive information, the physical technology to make it all work is still in its infancy.
尽管构建全新的量子互联网会彻底改变我们传输敏感信息的方式，但支撑这一切落地的物理技术目前仍处于起步阶段。

You're trying to make them forward compatible so that when material scientists and condensed matter people give you more instrumentation and devices, more advanced devices that you can plug them in.
你在努力让它们具备向前兼容性，这样当材料科学家和凝聚态物理领域的人员为你提供更多仪器和设备、更先进的设备时，你就能把它们接入使用。

In 2020, the US Department of Energy laid out a blueprint for a national quantum network using its 17 national laboratories, including Fermilab as the central network for the project.
2020年，美国能源部利用其17个国家实验室制定了一份国家量子网络蓝图，其中费米实验室作为该项目的中央网络。

Scientists and researchers say it represents one of the most important technological frontiers of the 21st century and hope to implement it in the next decade.
科学家和研究人员表示，这代表了21世纪最重要的技术前沿之一，并希望能在未来十年将其落地应用。

There has been a lot of investment worldwide and in the US, for I want to say 30, maybe 40 years, it is well funded and explored, and there's both industry and academia and government that has invested.
全球范围内以及美国都有大量投资，我想说大约有30年，甚至可能40年，资金充足且研究深入，产业界、学术界和政府都进行了投资。

But experts say today's technology which only teleports information is still a long way off from realizing the dreams made popular by Star Trek.
但专家表示，如今只能传送信息的技术，距离实现《星际迷航》所普及的梦想仍有很长的路要走。

It doesn't mean that we can beam up Scotty or anybody else or a cat or anything else.
这并不意味着我们可以把斯科特或者任何其他人、或者一只猫、或者其他任何东西传送上去。

We cannot move matter right now, and if we ever manage to do it, it's going to be with a different process.
我们现在还无法移动物质，而如果我们有朝一日能够做到，也得通过一种截然不同的方法。

A process that unlike quantum teleportation still only exists in the realm of science fiction.
这一过程与量子隐形传态不同，目前仍只存在于科幻小说的范畴中。

What if you could control your car, turn on your oven, or sign your name by touching an invisible screen?
要是你能通过触摸一块看不见的屏幕操控汽车、打开烤箱、或是签名，会怎么样？

Ultraleap, a British and California firm, uses ultrasound waves to create the sensation of touch mid-air. A camera tracks hand motions.
英国与美国加州合资的公司Ultraleap利用超声波在空中制造触感。摄像头追踪手部动作。

You can keep your eyes on the road. You can feel the button go click.
你可以让眼睛一直盯着路面。你可以感觉到按钮发出咔嗒一声。

Ultraleap works with museums, car manufacturers, and other industries to create invisible screens in mid-air, and with augmented reality headsets to bring more information to people's experiences.
Ultraleap与博物馆、汽车制造商及其他行业合作，在空中打造隐形屏幕，并借助增强现实头显丰富人们的体验感受。

With the pandemic, Ultraleap turned its technology toward touch screens in restaurants and stores, touch screens that some people no longer want to touch.
疫情期间，Ultraleap公司将其技术转向了餐厅和商店中的触摸屏，因为有些人不再愿意触碰这类传统的触摸屏。

People are becoming so much more conscious of what they're touching, particularly in an out of home environment, where they don't have so much control over what they're touching, and what may have touched it before.
人们对自己触摸到的东西越来越在意，尤其是在户外环境中，因为他们对自己触摸的对象以及此前可能接触过它的事物，并没有太多掌控力。

The technology may take a little getting used to. In a car to control music, temperature or the map, there are two gestures to learn.
这项技术可能需要一点时间来适应。在车内控制音乐、温度或地图，有两个手势需要学习。

One is a pinch gesture which is used for selection, and then the other one is what we call the drop the mic gesture, where you just release your hand like that.
一种是用于选择的捏合手势，另一种是我们所说的“扔麦”手势，你只需像那样松开手。

The driver can feel vibrations with the gesture as if you are physically touching something.
司机可以通过手势感受到振动，仿佛真的触碰到了什么东西。

You're feeling little pulses at each increment of the setting. It's a new way of interacting with machines touch free and in the air.
你会在设置的每一次档位变化时感受到轻微的脉冲震动。这是一种无需接触、在空中就能与机器互动的全新方式。

January 28th, 1986, before a television audience, seven passengers aboard the Space Shuttle Challenger took flight from the Kennedy Space Center in Florida.
1986年1月28日，在电视观众面前，挑战者号航天飞机上的七名乘客从佛罗里达州的肯尼迪航天中心起飞。

Among them was Christa McAuliffe, who was selected in a nationwide search for a teacher to be NASA's first citizen passenger in space.
其中一位是克里斯塔·麦考利芙，她是在全国范围内选拔出来的教师，将成为NASA首位进入太空的普通公民乘客。

I don't think any teacher has ever been more ready to have two lessons in my life.
我认为在我的教学生涯中，从来没有哪位老师像我这样准备好上两节课。

I've been preparing these in September, and I just hope everybody tunes in on day 4 now to watch the teacher teaching from space.
我一直在九月份准备这些内容，现在只希望大家都能在第四天收看老师从太空授课。

Just 73 seconds after takeoff disaster after a rubber seal in one of the shuttle's twin booster rockets failed, triggering an explosion that doomed all on board.
起飞后仅73秒，灾难降临——航天飞机的两枚助推火箭之一的橡胶密封圈失效，引发爆炸，致使机上所有人员全部遇难。

Then president Ronald Reagan eulogized the crew and called them heroes.
随后，罗纳德·里根总统悼念了机组人员，并称他们为英雄。

And while the flight exposed failures in NASA management who ignored safety warnings from scientists, it's widely regarded as planting the seed for shuttle development in today's commercial space flights.
尽管这次飞行暴露了NASA管理层忽视科学家安全警告的失误，但人们普遍认为，它为当今商业太空飞行中的航天飞机发展播下了种子。

Companies like SpaceX have even flown missions to the International Space Station, where on Wednesday astronauts Michael Hopkins and Victor Glover spacewalk to finish installing a European science platform and complete long-term battery upgrades.
像SpaceX这样的公司甚至已经执行了前往国际空间站的任务，周三，宇航员迈克尔·霍普金斯和维克多·格洛弗在那里进行太空行走，以完成欧洲科学平台的安装，并完成长期电池升级任务。

The advancements can further research on Earth observation, robotics, material science and astrophysics. This according to a tweet from the space station's twitter account.
这些进展可进一步推动地球观测、机器人技术、材料科学和天体物理学领域的研究。这一消息来自空间站推特账号发布的一条推文。

Back on Earth, climatologists sounded yet another alarm this week. An estimated 28 trillion metric tons of ice have melted from icesheetsand glaciers since the mid 1990s.
回到地球，气候学家本周再次发出警报。自20世纪90年代中期以来，冰盖和冰川估计已有28万亿公吨的冰融化。

That's 57 percent faster than it was three decades ago, per report scientists published Monday in the journal The Cryosphere.
根据科学家们周一在The Cryosphere期刊上发表的报告，这比三十年前快了57%。

In that time, global sea levels have risen three and a half centimeters, while the global temperature has gone up by one degree Celsius.
在此期间，全球海平面上升了3.5厘米， 而全球气温上升了一摄氏度。

Finally this week, abutcherin Scotland sent a bag of haggis into the atmosphere.
苏格兰的一位屠夫将一袋哈吉斯送入了大气层。

Simon Howie's bag of organ meats climbed more than 32 kilometers before falling back to the ground.
西蒙·豪伊的那袋动物内脏上升了超过32公里，然后才落回地面。

He claims it was the first haggis to reach such heights and says he hopes it inspires children's interest in space.
他声称这是第一份到达如此高度的哈吉斯，并表示他希望这能激发孩子们对太空的兴趣。

Scientists say the developing El Niño is already the strongest ever recorded, with sea temperatures in a key region of the Pacific more than three degrees above average, and this event is not expected to peak until later this year.
科学家表示，目前正在形成的厄尔尼诺现象已达到有记录以来最强水平，太平洋一个关键海域的海水温度比平均水平高出三度以上，而此次厄尔尼诺预计要到今年晚些时候才会达到峰值。

El Niño is a natural climate phenomenon that occurs when unusually warm water develops across the tropical Pacific, disrupting weather patterns around the world.
厄尔尼诺是一种自然气候现象，当热带太平洋出现大范围异常偏暖的海水时便会发生，扰乱全球各地的天气模式。

The Met Office says its impacts are already being felt, with wildfires in Indonesia and low water levels in the Panama Canal restricting international shipping. As it develops, it's expected to bring droughts and wildfires to parts of Australia, South America and southern Africa, while coastal Peru and Ecuador face the threat of torrential rain and flooding.
英国气象局表示，厄尔尼诺现象的影响已开始显现：印度尼西亚发生野火，巴拿马运河水位偏低，使国际航运受到限制。随着厄尔尼诺的进一步发展，预计澳大利亚、南美洲和南部非洲的部分地区将遭遇干旱和野火。与此同时，秘鲁和厄瓜多尔沿海地区面临暴雨和洪水的威胁。

The Sun has set, and you're headed to a train station in Stockholm with your overnight bag. You board the sleeper train, change into your comfortable clothes, enjoy the scenery through the window for a while before laying your head down to rest. Snoring from the other passengers in your shared cabin delays your bedtime, but the gentle motion and white noise eventually send you to sleep. The next morning, just over 12 hours later, you wake up in Germany's second largest city, Hamburg. "It still sounds like a long time, but you go to sleep, and it's such a nice atmosphere on the train," says Julia Senninger, a fan of sleeper trains.
太阳已经落山，您带着过夜行李前往斯德哥尔摩的火车站。 登上卧铺列车，换上舒适的衣服，欣赏一下窗外的风景，然后就低头休息。 共用客舱内其他乘客的鼾声会延迟您的就寝时间，但轻柔的动作和白噪音最终会让您入睡。 第二天早上，12 个多小时后，您在德国第二大城市汉堡醒来。 “听起来还是很长一段时间，但你很快就睡着了，火车上的气氛真好，”卧铺火车的粉丝朱莉娅·森宁格 (Julia Senninger) 说道。

Before budget airlines made flights across Europe so quick and cheap, sleeper trains were a popular way to cover large distances without wasting daylight or paying for a place to stay. After a period of decline, sleeper trains in Europe are making a comeback.Belgian-Dutch company European Sleeper launched the Brussels to Milan route in September 2026 and has announced a new route connecting Belgium, the Netherlands and Sweden, scheduled to open in 2028. Other train companies Trenitalia and Nightjet have also announced plans for new international routes. Companies are rushing to meet high demand.
在廉价航空公司提供如此快捷、便宜的穿越欧洲的航班之前，卧铺火车是一种流行的长途旅行方式，无需浪费日光或支付住宿费用。 经过一段时间的衰退后，欧洲的卧铺列车正在卷土重来。比利时-荷兰公司European Sleeper于2026年9月推出了布鲁塞尔至米兰的航线，并宣布了一条连接比利时、荷兰和瑞典的新航线，计划于2028年开通。其他火车公司Trenitalia和Nightjet也宣布了新的国际航线的计划。 公司正在争先恐后地满足高需求。

The rise in popularity is partly due to changing attitudes and increased awareness surrounding climate change. The carbon footprint of an electric-powered train is just a fraction of a flight. But there's more to it. Sleeper train fan Julia Senninger says trains are simply more fun. You meet more people and can have interesting conversations. Cat Jones, founder of the flight-free travel agency Byway, says, "The point of travel is the experience rather than just the arrival." So, people are buying into the idea that the journey to your destination is also part of the trip. Besides the convenience of starting and ending your journey in a city centre, there's also a sense of romance and adventure when you imagine whizzing through unknown landscapes and foreign villages while you sleep.
受欢迎程度的上升部分归因于人们对气候变化的态度的改变和意识的增强。 电动火车的碳足迹只是飞行的一小部分。 但还有更多。 卧铺火车迷朱莉娅·森宁格 (Julia Senninger) 表示，火车更有趣。 你会认识更多的人，并可以进行有趣的对话。 不搭乘航班的旅行社 Byway 的创始人卡特·琼斯 (Cat Jones) 表示：“旅行的重点在于体验，而不仅仅是抵达。” 因此，人们相信到达目的地的旅程也是旅行的一部分。 除了在市中心方便地开始和结束旅程之外，当您想象在睡觉时飞驰穿过未知的风景和外国村庄时，还会有一种浪漫和冒险的感觉。

In Europe, the sleeper train comeback does not come without challenges. Competing with budget airlines, some sleeper train routes have disappeared, even while new ones have launched. Problems with infrastructure, cost and availability mean that the high demand for a more sustainable travel option is not currently being met.
在欧洲，卧铺列车的卷土重来并非没有挑战。 与廉价航空公司竞争，一些卧铺火车线路已经消失，尽管新线路已经开通。 基础设施、成本和可用性方面的问题意味着对更可持续的旅行选择的高需求目前尚未得到满足。
