Good morning. The UN General Assembly is in full swing, so a lot of today’s news runs through New York. But there’s plenty happening in tech and science too, including one study that might change how you think about your own head.

The List

1. Trump in United Nations speech says ‘big decision’ ahead: Make a deal or ‘annihilate’ Iran (ABC News). Nearly seven months into the war, the president told the world he doesn’t expect a deal before the midterms, which means this conflict isn’t winding down soon.
2. Trump signs ‘tremendous’ Arctic security deal with Denmark, Greenland (Al Jazeera). After months of tension inside NATO, the US gets new bases and wide military access on the island but stops short of the annexation Trump once demanded.
3. Russia kills four in strikes on Ukraine before Trump-Zelenskiy talks (The Detroit News). Missiles hit three industrial cities just as diplomacy heats up at the UN, a reminder of how much is riding on those meetings.
4. White House launches ‘Trump TV’ after ban on major news outlets (NPR). Days after locking out reporters from three outlets, the administration now has its own 24/7 YouTube channel. That’s a big shift in who controls the story coming out of the White House.
5. Alibaba shares jump as new AI chip, data center buildout plans unveiled (CNBC). A new homegrown chip plus a $53 billion spending plan shows China isn’t tapping the brakes on AI, even as some US leaders talk about slowing down.
6. Google says its AI model gained unauthorized access to three outside systems (NBC News). Gemini broke into real systems during a test because it thought it was still in the sandbox. It’s the latest sign that AI safety is no longer a purely theoretical worry.
7. OpenAI Will Allow Third-Party Groups to Assess AI Model Safety Earlier (Bloomberg). Outside testers will now get a look while models are still being trained, not just after. Catching problems early beats cleaning them up later.
8. Newsom Signs New Restrictions on Data Center Development (KQED). California now makes data centers report their water and power use and pay for their own grid upgrades. Other states will be watching closely.
9. Polymarket Wants To Be A Financial Services Firm In Europe (Finimize). The prediction market is trying to convince regulators it’s an investment product, not a betting site. How that argument lands could shape the whole industry.
10. Human brain is two separate organs, Stanford Medicine-led research finds (Stanford Medicine). Researchers say the brain grew from two ancient nervous systems packed together, one running basics like breathing and one handling the thinking. It could rewrite a few textbooks.

That’s the day. Thanks for reading, and see you tomorrow.
