When Human-AI Teams Thrive and When They Don’t
Summary: A new study reveals that while human-AI collaboration can be powerful, it depends on the task. Analysis of hundreds of studies found that AI outperformed human-AI teams in decision-making…
Key Biochemical Trigger of Huntington’s Disease Progression Identified
Summary: Researchers have identified a crucial biochemical mechanism that could allow Huntington’s disease to be studied before symptoms appear, offering hope for early intervention. The team found that disrupted dopamine…
Childhood Attention Problems and Genes Linked to Psychosis Risk
Summary: Childhood attention issues, coupled with genetic predispositions, increase the likelihood of experiencing psychotic-like symptoms in adolescence. By analyzing data from 10,000 youths, researchers discovered that variability in attention spans…

Summary: New research shows that prenatal exposure to cannabis can negatively impact children’s thinking and behavioral skills, including impulse control, attention, and aggression, which are key for academic and social…
How Curiosity Styles Shape Wikipedia Use and Learning
Summary: A study of global Wikipedia browsing patterns reveals three curiosity styles: the focused “hunter,” the exploratory “busybody,” and the creative “dancer.” Data from 482,760 readers in 50 countries shows…
Depression Alters Brain Circuits, Heightening Negative Perception
Summary: Scientists have identified how depression alters the brain’s response to positive and negative stimuli, particularly in the amygdala, a key emotional processing center. The study found that depression reduces…
Individual Reward-Seeking Predicts Nicotine Response
Summary: A new study finds that individualistic reward-seeking behaviors in mice can predict their responses to nicotine. Conducted in a semi-natural environment called Souris-City, the research observed how male mice…
Chick Calls Reveal Emotional States
Summary: Researchers have developed a way to measure stress in baby chicks using vocalizations, offering new insights into animal emotions. The study found that chicks alone produced higher-pitched, louder calls,…
Brain Signals Reveal How Aggression and Arousal Are Encoded
Summary: New research has uncovered that brain signals for aggression in male mice and sexual arousal in female mice are encoded by similar neural mechanisms. The studies found that a…
