The Download: inside animals’ minds, and how to make AI agents useful

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

What do jumping spiders find sexy? How DIY tech is offering insights into the animal mind.

Studying the minds of other animals comes with a challenge that human psychologists don't usually face: Your subjects can't tell you what they're thinking.

To get answers from animals, scientists need to come up with creative experiments to learn why they behave the way they do. Sometimes this requires designing and building experimental equipment from scratch.

These contraptions can range from ingeniously simple to incredibly complex, but all of them are tailored to help answer questions about the lives and minds of specific species. Do honeybees need a good night's sleep? What do jumping spiders find sexy? Do falcons like puzzles? For queries like these, off-the-shelf gear simply won't do. Check out these contraptions custom-built by scientists to help them understand the lives and minds of the animals they study.

How ChatGPT search paves the way for AI agents

It's been a busy few weeks for OpenAI. Alongside updates to its new Realtime API platform, which will allow developers to build apps and voice assistants more quickly, it recently launched ChatGPT search, which allows users to search the internet using the chatbot.

Both developments pave the way for the next big thing in AI: agents. These AI assistants can complete complex chains of tasks, such as booking flights. OpenAI's strategy is to both build agents itself and allow developers to use its software to build their own agents, and voice will play an important role in what agents will look and feel like.

Melissa Heikkila, our senior AI reporter, sat down with Olivier Godement, OpenAI's head of product for its platform, and Romain Huet, head of developer experience, last week to hear more about the two big hurdles that need to be overcome before agents can become a reality. Read the full story.

The big story

The hunter-gatherer groups at the heart of a microbiome gold rush

December 2023

Over the last couple of decades, scientists have come to realize just how important the microbes that crawl all over us are to our health. But some believe our microbiomes are in crisis-casualties of an increasingly sanitized way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer's.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don't live in the polluted, processed environment that most of the rest of us share.

They've been studying the feces of people like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. But they're having to navigate an ethical minefield in order to do so. Read the full story.
