James Evans, a University of Chicago sociologist and data scientist, discusses the limitations of training AI to think like humans. He argues that this approach stifles scientific discovery and advocates for the creation of 'cognitive aliens'—AIs that think differently to unlock breakthroughs. Evans explores how expanding AI’s sensory capabilities can lead to new forms of innovation and emphasizes the need for a shift in AI development to overcome biases in research. He also addresses AI's paradoxical role in both hindering and enhancing scientific inquiry.

When someone we know or love starts to develop psychological issues, we don't often associate it with a form of dementia. However, this trait is one of the most common signs of frontotemporal dementia (FTD) — the most common neurodegenerative disease in people under the age of 65. In his new book, Mysteries of the Social Brain: Understanding Human Behavior Through Science, Dr. Bruce Miller highlights his experiences observing people with FTD and what they have taught him about what he calls the "social brain."Dr. Bruce Miller has been observing people with FTD for decades in the Memory and Aging Center at the University of San Francisco, where he is also Professor of Neurology and the Founding Director of the Global Brain Health Institute. He shares key insights on how to keep our "social brain" healthy and how it can even unlock our creative potential.
