How DIY tech is offering insights into the animal mind.Studying the minds of other animals comes with a challenge that human psychologists dont usually face: Your subjects cant tell you what theyre 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 nights sleep? What do jumping spiders find sexy? Do falcons like puzzles? For queries like these, off-the-shelf gear simply wont do. Check out these contraptions custom-built by scientists to help them understand the lives and minds of the animals they study.Betsy MasonThis piece is from the latest print issue of MIT Technology Review, which is all about the weird and wonderful world of food.

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. OpenAIs 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 Heikkil, our senior AI reporter, sat down with Olivier Godement, OpenAIs 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.
