人类首次造出六边形的盐
你有注意过家里的盐是什么形状的吗？反正不是六边形的。
但是现在科学家做出了六边形的盐。
这个，虽然它应该不会对你吃饭有半毛钱的影响，但从科研的角度来说价值挺大的。

While it probably won’t make it to your dining table, a new scientific achievement might be able to help in everything from radar equipment to electric cars: scientists have been able to form salt, aka sodium chloride (NaCl), in a hexagonal shape.
虽然这个新的科技成果可能不会登上你的餐桌，但可能会对很多领域有所帮助，如雷达设备、电动汽车等。科学家已经能合成六边形的盐了，也就是氯化钠（NaCl）。
This is work done at the smallest of scales, with researchers able to get a thin film of hexagonal salt to form on top of a layer of diamond, due to the chemical interaction of both film and diamond substrate - something the team actually predicted would happen in advance through simulations.
这是最精细的工作，研究人员在金刚石上制成六角形的盐薄膜，利用的是薄膜和金刚石基体之间的化学相互作用，这一作用该团队其实提前通过模拟就预测到了。
It’s the latest in a series of discoveries where scientists have been able to synthesise 2D materials with unusual crystal structures, and it’s partly this self-imposed restriction to two dimensions that is enabling new and exotic structures to be formed.
这是科学家利用不寻常的晶体结构合成二维材料的最新发现，在一定程度上，这种对二维空间的自我限制促成了新的奇异结构的形成。
“Initially we decided to perform only a computational study of the formation of new 2D structures on different substrates, driven by the hypothesis that if a substrate interacts strongly with the NaCl thin film, one can expect major changes in the structure of the thin film,” says material scientist Kseniya Tikhomirova from the Skolkovo Institute of Science and Technology (Skoltech) in Russia.
俄罗斯斯科尔科沃科技学院材料科学家Kseniya Tikhomirova说：“最初我们决定仅对不同基底上新的二维结构的形成进行计算研究，我们的假设是如果一种衬底与氯化钠薄膜产生强烈的相互作用，我们就能预测到薄膜的结构会有重大变化。”
特朗普威胁要关掉twitter
推特给特朗普的推文加上了特别的标签，提醒大众此账号的推文有严重歪曲事实之嫌，让大家保持警惕、记得查证。
总统先生不悦，毕竟他是个靠推特治国的总统，于是，扬言要封了推特。
外媒报道
Twitter Inc. would be welcome to move to France should the social-media platform face an adverse operating environment in the U.S., French Junior Digital-Affairs Minister Cedric O said in an interview with Radio J on Sunday.
周日，法国负责数字事务的初级部长塞德里克·奥在接受Radio J之声采访时说，如果美国经营环境对推特不利，欢迎这个社交媒体平台搬到法国。“If Twitter would consider at some point that the U.S. circumstances would no longer allow the company to develop according to its values, and to continue to expand, and if there would be too much instability for various reasons, the company would obviously be welcome in Europe, and particularly in France,” O said.
奥说：“如果推特什么时候认为美国的情况不再允许该公司按照自己的价值观发展、扩大业务，由于各种原因有太多的不稳定因素出现，欧洲一定会欢迎这家公司的到来，尤其是法国。”U.S. President Donald Trump on Thursday signed an executive order that seeks to limit liability protections for social-media companies after Twitter began selective fact checks of his posts on the platform. Twitter labeled two of the president’s posts about mail-in voting “potentially misleading” and provided links to news coverage of his comments.
美国总统唐纳德·特朗普在周四签署了行政命令，试图限制社交媒体公司的责任保护，此前推特开始对特朗普在该平台上发布的东西进行选择性事实核查。推特给总统关于邮寄选票的两则推文贴了“有误导可能”的标签，并附上有关他的评论的新闻报道的链接。Trump has accused the social media company of censorship and election interference and threatened to possibly shut down the service.
特朗普对这家社交媒体公司的审查和选举干涉进行了指责，威胁说可能要关闭这一服务平台。
麦当劳在新加坡重新推出椰子派
今年早些时候，新加坡的麦当劳重新推出了绵软的巧克力派，现在则推出了看起来很好吃的椰子派。
外媒报道
It appears that the fruity pie first came out in 2017, and McDonald’s Singapore has just brought it back in May 2020 for takeout and at the drive-thru. Perfect for summertime, right? The crispy pie crust is stuffed with a coconut filling and nata de coco bits, which is a coconut gel. Needless to say, people who love coconut will be all over this treat.
这款水果派好像最初是在2017年上市的，新加坡的麦当劳在2020年5月份重新推出了这款单品的外带服务，麦当劳得来速（麦当劳汽车餐厅）也有售。非常适合夏天吃吧？这款脆饼皮里塞满椰子馅和椰子泥。不用说，喜欢椰子的人一定都会去买。
哈利波特餐具来了
如果你想让家里的餐厅看起来有霍格沃茨大厅的感觉，塔吉特超市 Target 可能正有你需要的东西。
他们现在推出了多种“哈利·波特”主题的餐具套装。
外媒报道
These new additions include a Marauder Map dinnerware set, a Hogwarts Houses plate set, a Hogwarts emblem bowl set, and more.
这些新出的餐具包括活点地图餐具套装、霍格沃茨学院餐盘套装、霍格沃茨徽章碗套装等。
The Harry Potter Marauder’s Map 4-Piece Porcelain Place Setting Set is currently going for $39.99 and includes a dinner plate, salad plate, bowl, and mug. Each piece features an elegant golden design of the iconic map. In particular, the plate nods to the Animagus forms of characters James Potter, Sirius Black, Peter Pettigrew, and Remus Lupin, otherwise known as the original creators of the Marauder’s Map. These fine porcelain pieces are hand-wash only.
“哈利·波特活点地图”瓷器四件套现在售价为39.99美元，包括餐盘、沙拉盘、碗和杯子。每件上都有这个象征性地图的精美金色图案。盘子尤其向阿尼马格斯人物形象詹姆·波特、小天狼星布莱克、小矮星彼得和莱姆斯·卢平致敬，他们都是活点地图的原创者。这些精美的瓷器只能手洗。
