The Download: rethinking child safety and fossil-fueled farming

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. Digital harms have become the defining fear of American parents. In response, they’re increasingly turning to content-monitoring apps that scan their children’s texts, photos, emails, and chats, issuing alerts whenever an algorithm flags something it deems dangerous.

These tools have had genuine successes, preventing suicide attempts, intercepting predators, and averting school shootings. But they can also cause harm themselves, from false alarms and unnecessary interventions to damaged trust and anxiety. Child-safety researchers say better approaches exist.

Here’s what they think those could look like. This article is from our latest print magazine, which is all about kids. Subscribe now to get every issue as soon as it lands.

Fertilizer prices have been on a roller coaster this year, driven in part by trade disruptions and high natural-gas prices. That’s because natural gas is both an energy source and a chemical input in the production of ammonia, a key fertilizer ingredient. The war in Iran has pushed natural-gas prices higher and disrupted fertilizer trade through the Strait of Hormuz—and its closure could make access harder still for some of the world’s poorest countries.

Let’s take a closer look at the surging fertilizer prices, and how a few climate-friendly alternatives could bring farmers some relief.

They also disagreed about the company’s big idea: de-extinction. Colossal kept the location of the mystery clones secret, and even their purpose was murky to some scientists.
