How lasers could help provide fuel for nuclear reactors

激光技术如何助力核反应堆燃料供应

Nuclear power provides about 9% of global electricity today, and that fraction could tick up as countries look to build new reactors. New, cheaper methods to obtain fuel could help ensure that those nuclear projects stay on track. One of those methods is called laser enrichment. It allows you to separate out the material you want (in this case, uranium) from others in a mixture of old waste. A company called Global Laser Enrichment (GLE) is about to start testing whether the technology works at commercial scale. Read our story about their efforts. —Casey Crownhart 核能目前提供了全球约 9% 的电力,随着各国寻求建造新的反应堆,这一比例可能会上升。获取燃料的更廉价新方法有助于确保这些核项目顺利进行。其中一种方法被称为激光浓缩。它能让你从旧废料混合物中分离出所需的材料(在本例中为铀)。一家名为“全球激光浓缩”(GLE)的公司即将开始测试该技术是否能在商业规模上运作。阅读我们关于他们工作的报道。——Casey Crownhart

The quest to keep organs alive outside the body

让器官在体外存活的探索

It’s super difficult to freeze organs. Once ice forms in them, they’re done. The ice crystals create all kinds of damage and render the organs unusable. That hasn’t stopped many researchers from trying. In new research, one team has been able to supercool the kidneys of pigs and preserve them for days. The kidneys survived being stored at −4 °C (25 °F) and eventually reimplanted back into pigs. And that’s just the latest development in a field that is positively buzzing. Read about why it’s such an exciting time for organ preservation—and what could be coming next. —Jessica Hamzelou 冷冻器官极其困难。一旦器官内形成冰晶,它们就报废了。冰晶会造成各种损害,使器官无法使用。但这并没有阻止许多研究人员的尝试。在一项新研究中,一个团队成功地对猪的肾脏进行了过冷处理,并保存了数天。这些肾脏在 -4°C (25°F) 的环境下储存后存活下来,并最终被重新植入猪体内。这只是该领域最新的一项进展,目前该领域正处于活跃期。阅读关于为何现在是器官保存领域激动人心的时刻,以及未来可能的发展。——Jessica Hamzelou

Inside a romance scam compound—and how people get tricked into being there 走进浪漫诈骗园区——以及人们是如何被诱骗至此的

Gavesh’s journey started, seemingly innocently, with a job ad on Facebook promising work he desperately needed. Instead, he found himself trafficked into a business commonly known as “pig butchering”—a form of fraud in which scammers form close relationships with targets online and extract money from them. The Chinese crime syndicates behind the scams have netted billions of dollars, and they have used violence and coercion to force their workers to carry out the frauds from large compounds, several of which operate openly in the quasi-lawless borderlands of Myanmar. Read our story about these scam syndicates and how they could be broken up. — Peter Guest and Emily Fishbein Gavesh 的旅程始于 Facebook 上一则看似无害的招聘广告,承诺提供他急需的工作。然而,他发现自己被贩卖到了俗称“杀猪盘”的行业——这是一种诈骗形式,骗子在网上与目标建立亲密关系并从中骗取钱财。这些诈骗背后的中国犯罪集团已获利数十亿美元,他们利用暴力和胁迫手段强迫员工在大型园区内实施诈骗,其中一些园区在缅甸近乎无法无天的边境地区公开运作。阅读我们关于这些诈骗集团以及如何瓦解它们的报道。——Peter Guest 和 Emily Fishbein
