Bumblebees Show Chimp-Like Problem-Solving Skills
New research shows bumblebees can solve the classic box-and-banana problem, suggesting insect brains may rival larger vertebrates in cognitive flexibility.
AI's Inner Language for Depression Reveals Interpretable Symptom Vectors
A new study reveals that a large language model's internal activations encode symptoms of depression in a way that aligns with clinical judgment, enabling interpretable assessment.
Brain Scan Reveals Alzheimer's Changes Years Before Plaques
New research finds structural brain changes up to 7+ years before amyloid plaques are visible on PET scans, potentially enabling earlier detection.
SC-TauPath: AI Maps Tau Spread in Alzheimer's via Brain Connections
A new AI framework, SC-TauPath, maps how tau protein spreads in Alzheimer's by analyzing structural brain connections, validating Braak staging.
Dementia Risk After 90: Genes, Sex, and Race Still Matter
A large study of people over 90 finds dementia risk still varies by sex, race, and genetics, with women and Black participants at higher risk. Some resilient individuals defy risk factors, offering clues to brain health.
Paper vs. Tablet: Brain Integrates Narratives Better on Paper
New fMRI study shows reading on paper reduces brain effort in integrating story narratives compared to tablets, suggesting tactile cues help comprehension.
Scientists Discover Hippocampal 'Memory Switchboard' That Prevents Forgetting
New research reveals a 'memory switchboard' in the hippocampus that helps the brain reuse cells for new memories without erasing old ones.
Human Brain's Slow-Maturing Immune Cells May Underpin Our Intelligence
Scientists found that human microglia take 4–8 years to mature, unlike weeks in mice, suggesting a human-specific gene that slows their development may boost cognitive abilities.
How Sparse Dictionaries Reveal the Hidden Structure of AI Concepts
New theory explains why AI models form interpretable features, offering insights into how our own brains might organize knowledge.
How Thinking of Mom Boosts Toddler Brain Synchrony
A new study shows that 3-4-year-olds' belief they're interacting with their mother—even when they aren't—enhances brain-to-brain synchrony, highlighting the power of attachment representations.
Evolutionary Algorithms Evolve Better Brain-Inspired Reservoir Networks
Researchers used evolution to design reservoir computing networks, outperforming random designs and showing task difficulty shapes architecture.
New Brain Probe Rewrites Rules of Neural Communication
An ultra-thin silicon probe lets scientists watch and control hundreds of neurons at once, revealing that brain regions work more independently than believed.
