Summary: A new study explores how human behaviors spread through social networks, revealing that long ties—connections that bridge distant parts of a network—significantly accelerate the adoption of new behaviors and ideas. Contrary to previous beliefs that closely knit groups are more effective in spreading complex behaviors, this study demonstrates […]
Summary: Engaging in complex, thought-provoking work may lower the risk of mild cognitive impairment (MCI) in older age. Conducted by researchers at Oslo University Hospital, the study analyzed job demands of over 7,000 people across 305 occupations in Norway, linking higher cognitive job demands in one’s 30s through 60s […]
Summary: Researchers made significant progress in understanding color perception by identifying non-cardinal retinal ganglion cells (RGCs) in the human fovea. These cells may explain complex color perceptions beyond the traditional models established by the cardinal directions of color detection. Utilizing adaptive optics, the team overcame challenges posed by the […]

Summary: Researchers successfully connected lab-grown brain tissues, mimicking the complex networks found in the human brain. This novel method involves linking “neural organoids” with axonal bundles, enabling the study of interregional brain connections and their role in human cognitive functions. The connected organoids exhibited more sophisticated activity patterns, demonstrating […]

Summary: Researchers innovated a method to evolve diverse personality traits in dialogue AI using a language model and the prisoner’s dilemma game. By simulating scenarios where AI agents choose between cooperation and self-interest, the study demonstrates the potential of AI to mimic complex human behaviors. This evolutionary approach, integrating […]
Summary: A new study utilizing UK Biobank data has unveiled the genetic roots of left-handedness, pinpointing rare variants in the beta-tubulin gene TUBB4B significantly associated with this trait. These findings not only shed light on the complex interplay between genetics and brain asymmetry but also link left-handedness with neurodevelopmental […]
