Cryptography may offer a solution to the massive AI-labeling problem 

The White House wants big AI companies to disclose when content has been created using artificial intelligence, and very soon the EU will require some tech platforms to label AI-generated content.

There’s a big problem, though: identifying material that was created by AI is a massive technical challenge. The best options currently available—detection tools powered by AI, and watermarking—are inconsistent, impermanent, and sometimes inaccurate.

But another approach has been attracting attention lately: C2PA. It’s an open-source internet protocol that relies on cryptography to encode details about the origins of a piece of content. The problem is, it’s far from a fix-all solution. Read the full story.

The big story

Eight ways scientists are unwrapping the mysteries of the human brain

August 2021

There is no greater scientific mystery than the brain. It’s made mostly of water; much of the rest is largely fat. Yet this roughly three-pound blob of material produces our thoughts, memories, and emotions. It governs how we interact with the world, and it runs our body.

Increasingly, scientists are beginning to unravel the complexities of how it works and understand how the 86 billion neurons in the human brain form the connections that produce ideas and feelings, as well as the ability to communicate and react. Here’s our whistle-stop tour of some of the most cutting-edge research—and why it’s important. Read the full story.
