特朗普政府取消会议，冻结在NIH招聘

美国国立卫生研究院的研究人员说，此举在整个机构中引起了恐惧和困惑。另外，模因硬币背后的技术是什么？

The Trump administration has imposed a range of restrictions on the National Institutes of Health, affecting meetings, travel, hiring, funding, and communications.

特朗普政府对美国国立卫生研究院施加了一系列限制，影响了会议，旅行，招聘，资金和沟通。

Scientists expressed alarm about what this could mean for ongoing research, with no clear timeline for if or when the freeze would be lifted.

科学家对这对正在进行的研究可能意味着什么，没有明确的时间表，即是否或何时冻结。

Flora Lichtman is joined by Casey Crownhart, climate editor at the MIT Technology Review, to catch up on this and other big science stories of the week, including what’s coming next this year for nuclear power, why a record amount of snow fell in the Southeast this week, and new research on the surprisingly complex biology of a manta ray tail.

MIT技术评论的气候编辑Casey Crownhart加入了弗洛拉·利希特曼本周，以及关于Manta Ray Tail令人惊讶的复杂生物学的新研究。

Also this week: A few days before President Trump’s inauguration, he hosted a “crypto ball” in Washington, D.C. That night, he unveiled his very own meme coin—a kind of digital asset that has gained a reputation for facilitating scams. Soon after, first lady Melania Trump also launched her own meme coin. After its launch, Trump’s coin’s market capitalization reached billions of dollars.

同样是本周：在特朗普总统就职典礼之前的几天，他当晚在华盛顿特区举办了一个“加密舞会”，他揭开了自己的模因硬币，这是一种以促进骗局的声誉。不久之后，第一夫人梅拉尼亚·特朗普（Melania Trump）也发行了自己的模因硬币。在推出后，特朗普的硬币的市值达到了数十亿美元。

This isn’t the first time meme coins have gotten a lot of attention—you might remember Elon Musk joked about another one called Dogecoin on SNL in 2021—but it is the first time that this technology has been used by a sitting president. So what exactly is a meme coin anyway? How does the blockchain play into all this? And how might a president use it differently than an internet celebrity?

这不是Meme硬币第一次引起人们的关注 - 您可能还记得埃隆·马斯克（Elon Musk）在2021年在SNL上开玩笑说Dogecoin开玩笑 - 但这是这项技术首次被现任总裁使用。那么，无论如何，模因硬币到底是什么？区块链如何发挥所有作用？总统与互联网名人的使用方式如何不同？

To find out more, Flora Lichtman talks with Liz Lopatto, a senior writer at The Verge who covers cryptocurrency and business, about how this market started, how Trump could use meme coins, and where the crypto market could go next.

为了了解更多信息，Flora Lichtman与Verge的高级作家Liz Lopatto进行了交谈，他涵盖了加密货币和业务，谈论该市场的开始，特朗普如何使用Meme硬币以及加密货币市场的下一步。
