An unprecedented brain study has delivered fresh clues about consciousness—suggesting it's more about perception than planning. Two leading theories went head-to-head, but neither emerged victorious.

What gives rise to human consciousness? Are some parts of the brain more important than others? Scientists began tackling these questions in more depth about 35 years ago. Researchers have made ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

The phrase “regaining consciousness” usually means recovering from unconscious states such as sleep and anesthesia. But I use it to mean rescuing consciousness from intellectual mistakes that impede ...

In November 2022, OpenAI introduced ChatGPT, a chatbot that has garnered significant attention for its ability to understand and converse at a human-like level. In 2020, I conducted an interview with ...
