Octopuses haven’t shared a common ancestor with humans in at least 600 million years. But somehow, separately, these invertebrates evolved remarkable problem-solving abilities, curiosity and intelligence. Octopus researcher Jennifer Mather, PhD, talks about what we know about octopus behavior and cognition, how they evolved to be so smart, how the octopus brain is structured, and what can we learn about thinking and intelligence in general from studying how it evolved in a species so far removed from us.

APA’s 2024 Work in America survey found that younger workers are more likely than older workers to feel stressed, lonely and undervalued at work. Dennis Stolle, PhD, senior director of APA’s office of applied psychology, talks about why that might be and how employers can create workplaces where all ages can thrive; as well as other key findings from the survey including the state of remote work, hybrid work and four-day work weeks.

A few decades ago, the idea of being able to interact directly with a computer using only your thoughts would have sounded like science fiction. But today researchers and companies are testing brain-computer interfaces that allow patients to move a computer cursor or control a prosthetic limb directly with their thoughts. Nicholas Hatsopoulos, PhD, discusses the future of brain-computer interfaces, how they work, the practical challenges researchers face, and what scientists have learned about the brain as they develop this technology.
