What China’s critical mineral ban means for the US
This week, China banned exports of several critical minerals to the US, marking the latest move in an escalating series of tit-for-tat trade restrictions between the world’s two largest economies.
In explicitly cutting off, rather than merely restricting, materials of strategic importance to the semiconductor, defense, and electric vehicle sectors, China has clearly crossed a new line in the long-simmering trade war.
But at the same time, it selected minerals that won’t cripple any industries—which leaves China plenty of ammunition to inflict greater economic pain in response to any further trade restrictions that the incoming Trump administration may impose. Read more about what drove China’s decision, how it affects climate tech and what’s likely to happen next.

3 things that didn’t make the 10 Breakthrough Technologies of 2025 list
Next month, MIT Technology Review will unveil the 2025 list of 10 Breakthrough Technologies. Every year, our newsroom looks across the fields we cover for technologies that are having a true breakthrough moment. This annual package highlights the technologies that we think matter most right now.
In the meantime, here are three technologies that we considered including on the 2025 list but ultimately decided to leave off. And although these nominees didn’t make the cut this year, they’re still worth keeping an eye on. Read the full story.

The US Department of Defense is investing in deepfake detection
What’s new: The US Department of Defense has invested $2.4 million over two years in deepfake detection technology from a startup called Hive AI. It’s the first contract of its kind for the DOD’s Defense Innovation Unit, which accelerates the adoption of new technologies for the US defense sector. Hive AI’s models are capable of detecting AI-generated video, image, and audio content.
Why? Although deepfakes have been around for the better part of a decade, generative AI has made them easier to create and more realistic-looking than ever before, which makes them ripe for abuse in disinformation campaigns or fraud. Defending against these sorts of threats is now crucial for national security. Read the full story.

Donating embryos for research is surprisingly complex
IVF is a success story for embryo research. But today, valuable embryos that could be used for research are being wasted, say researchers who gathered at a conference in central London earlier this week.
The embryos studied in labs have usually been created for IVF but are no longer needed by the people whose cells created them. And there’s a few reasons why embryos aren’t making it into research labs. Read the full story.

The big story
What is AI?
July 2024
AI is sexy, AI is cool. AI is entrenching inequality, upending the job market, and wrecking education. The AI boom will boost the economy, the AI bubble is about to burst. AI will increase abundance and empower humanity to maximally flourish in the universe. AI will kill us all.
