The Oxford University team behind the study says any drink at or above 65C is "very hot" and poses a potential risk. Compared with people who drank "warm" beverages, those who consumed "very hot" ones had around a three times higher risk of squamouscell oesophageal cancer. 开展这项研究的牛津大学团队表示，任何温度达到或超过 65 摄氏度的饮品都 “非常烫”，可能带来潜在风险。与饮用 “温热” 饮品的人相比，饮用 “非常烫” 饮品的人患食管鳞状细胞癌的风险约为其三倍多。
There are several thousand cases each year in the UK, but experts stress the overall chance of getting this cancer of the gullet is still low. Smoking and drinking alcohol are far bigger established risk factors, although waiting a few minutes for your hot drink to cool a bit is advisable. 英国每年有数千例食管癌病例，但专家强调，就普通人群而言，患上这种食管癌的总体风险仍然较低。吸烟和饮酒是已被证实、影响更大的风险因素。不过，等上几分钟，让热饮稍微冷却后再喝仍是明智之举。

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。

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。
