特朗普政府取消會議，凍結在NIH招聘

美國國立衛生研究院的研究人員說，此舉在整個機構中引起了恐懼和困惑。另外，模因硬幣背後的技術是什麼？

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

特朗普政府對美國國立衛生研究院施加了一系列限制，影響了會議，旅行，招聘，資金和溝通。

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

科學家對這對正在進行的研究可能意味著什麼，沒有明確的時間表，即是否或何時凍結。

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技術評論的氣候編輯Casey Crownhart加入了弗洛拉·利希特曼本週，以及關於Manta Ray Tail令人驚訝的複雜生物學的新研究。

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.

同樣是本週：在特朗普總統就職典禮之前的幾天，他當晚在華盛頓特區舉辦了一個“加密舞會”，他揭開了自己的模因硬幣，這是一種以促進騙局的聲譽。不久之後，第一夫人梅拉尼亞·特朗普（Melania Trump）也發行了自己的模因硬幣。在推出後，特朗普的硬幣的市值達到了數十億美元。

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?

這不是Meme硬幣第一次引起人們的關注 - 您可能還記得埃隆·馬斯克（Elon Musk）在2021年在SNL上開玩笑說Dogecoin開玩笑 - 但這是這項技術首次被現任總裁使用。那麼，無論如何，模因硬幣到底是什麼？區塊鏈如何發揮所有作用？總統與互聯網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.

為了了解更多信息，Flora Lichtman與Verge的高級作家Liz Lopatto進行了交談，他涵蓋了加密貨幣和業務，談論該市場的開始，特朗普如何使用Meme硬幣以及加密貨幣市場的下一步。
