Scientists are trying to figure out why.**\n\n*—Jessica Hamzelou*\n\nIt’s been hot in London this week. Really hot. A dangerous heat wave has hit Western Europe. On Wednesday, the UK recorded its highest ever June temperature at 36.1 °C (about 97 °F). But as the weather app on my phone confirmed, it *felt like* 39 °C.\n\nMuch of Western Europe is suffering, bringing awful consequences for agriculture, infrastructure, and the health system. But heat can also affect the brain.\n\nStudies have confirmed that as temperatures rise, people seem to get more irritable and [more violent](https://pmc.ncbi.nlm.nih.gov/articles/PMC11477092/). And they have shown that firefighters find it harder to focus immediately after heat exposure. Rising temperatures can also have particularly disastrous outcomes for children and people with mental health disorders.\n\nResearch on lab animals suggests that excessive heat can alter the function of chemical signals in our brains. But we still need a better understanding of the mechanisms behind these effects.\n\n[Here’s what scientists are learning about extreme heat’s impact on the brain](https://www.technologyreview.com/2026/06/26/1139760/heat-waves-mess-with-your-brain-scientists-are-trying-to-figure-out-why/?utm_source=the_download&utm_medium=email&utm_campaign=the_download.unpaid.engagement&utm_term=*%7CSUBCLASS%7C*&utm_content=*%7CDATE:m-d-Y%7C*).\n\n**This ****story**** is from The Checkup, our weekly biotech newsletter. ****Sign up**** to receive it in your inbox every Thursday.**\n\n*For more on Europe’s heat wave, read our stories on **why soaring temperatures are shutting down power plants** and **what they mean for the grid**.*\n\n**The must-reads**\n\n*I’ve combed the internet to find you today’s most fun/important/scary/fascinating stories about technology.*\n\n**1 The Trump administration has asked OpenAI to limit its next model release**\n\nIt wants to vet the first GPT 5.6 users before a wider launch.

Further investigation revealed that the remains were between 200 and 300 years old, and they were all African and African American.\n\nThis discovery came at an inflection point in scientific history. Breakthroughs in chemical and genetic analysis allowed researchers to figure out where many of these people were born, the physical challenges they faced, and even the routes they took from Africa to North America.\n\nToday, archaeologists are using techniques they could only dream of then: lasers, 3D photography, lidar, satellite imagery, and more. These tools are revealing where people came from, how ancient cities were built, and the lives of those who built them.\n\n[Read the full story on how archaeology is changing our understanding of the past](https://www.technologyreview.com/2021/04/28/1022982/data-archaeology-ancient-city-grid-burial-site/?utm_source=the_download&utm_medium=email&utm_campaign=the_download.unpaid.engagement&utm_term=*%7CSUBCLASS%7C*&utm_content=*%7CDATE:m-d-Y%7C).\n\n*—Annalee Newitz*\n\n**We can still have nice things**\n\n*A place for comfort, fun, and distraction to brighten up your day.
