The quest to find out how our bodies react to extreme temperatures
Climate change is subjecting vulnerable people to temperatures that push their limits. In 2023, about 47,000 heat-related deaths are believed to have occurred in Europe. Researchers estimate that climate change could add an extra 2.3 million European heat deaths this century. That’s heightened the stakes for solving the mystery of just what happens to bodies in extreme conditions.
While we broadly know how people thermoregulate, the science of keeping warm or cool is mottled with blind spots. Researchers around the world are revising rules about when extremes veer from uncomfortable to deadly. Their findings change how we should think about the limits of hot and cold—and how to survive in a new world. Read the full story.

Whales are dying. Don’t blame wind turbines.
Whale deaths have become a political flashpoint. There are currently three active mortality events for whales in the Atlantic, meaning clusters of deaths that experts consider unusual. And Republican lawmakers, conservative think tanks, and—most notably—President Donald Trump (a longtime enemy of wind power) are making dubious claims that offshore wind farms are responsible.
But any finger-pointing at wind turbines for whale deaths ignores the fact that whales have been washing up on beaches since long before the giant machines were rooted in the ocean floor. This is something that has always happened. And the scientific consensus is clear: There’s no evidence that wind farms are the cause of recent increases in whale deaths. Read the full story.

The State of AI: Energy is king, and the US is falling behind
In the age of AI, the biggest barrier to progress isn’t money but energy. That should be particularly worrying in the US, where massive data centers are waiting to come online. It doesn’t look as if the country will build the steady power supply or infrastructure needed to serve them all.
It wasn’t always like this. For about a decade before 2020, data centers were able to offset increased demand with efficiency improvements. Now, though, electricity demand is ticking up in the US, with billions of queries to popular AI models each day—and efficiency gains aren’t keeping pace.
If we want AI to have the chance to deliver on big promises without driving electricity prices sky-high for the rest of us, the US needs to learn some lessons from the rest of the world on energy abundance. Just look at China. Read the full story.

How Rust went from a side project to the world’s most-loved programming language
Many software projects emerge because—somewhere out there—a programmer had a personal problem to solve.
That’s more or less what happened to Graydon Hoare. In 2006, Hoare was a 29-year-old computer programmer working for Mozilla. After a software crash broke the elevator in his building, he set about designing a new computer language; one that he hoped would make it possible to write small, fast code without memory bugs.
That language developed into Rust, one of the hottest new languages on the planet. But while it isn’t unusual for someone to make a new computer language, it’s incredibly rare for one to take hold and become part of the programming pantheon. How did Rust do it? Read the full story.
