AI Automates Cognitive Testing of Wild Monkeys With 97% Accuracy
CapuchinAI uses facial recognition and touchscreens to test wild capuchin monkeys' cognition in Costa Rica, identifying individuals with 97% accuracy.
APOE4 Alzheimer's Gene Damages Brain Vessels, Waste Clearance
Mount Sinai researchers find APOE4 actively scars brain blood vessels and blocks astrocyte waste disposal — and blocking TGF-β reversed the damage in aged mice.
Dogs and Humans Share the Same Consonant Bias in Speech
An EEG study led by Boglárka Morvai shows dogs, like humans, use consonants rather than louder vowels to find word boundaries in continuous speech.
Cultural Evolution: How Communicating Networks Learn Better
A new neural network model shows that a population of communicating agents can learn progressively better descriptions of its environment — a ratchet-like process called Cultural Evolution.
Brain Signals for Error Detection Decoded Under Multisensory Feedback
New research shows a multi-branch EEGNet model can reliably decode error-related brain potentials even with mixed visual, auditory, and tactile feedback — a step toward better brain-computer interfaces.
More Electrodes, Faster Minds? Rethinking BCI Bandwidth
A new Perspective argues that brain-computer interface gains don't scale linearly — embodiment, learning, and personal confirmation limit meaningful thought output.
More REM Sleep Linked to Lower Risk of 83 Diseases
A new study of 95,559 people found that more REM sleep was linked to lower risk of 83 conditions, including dementia and heart failure.
Brain-Inspired AI Mimics Hippocampal Maps to Cut Energy Use
Researchers at Graz University of Technology built an AI that plans like the brain's hippocampus, using cognitive maps and stochastic search to cut energy use dramatically.
US Suicide Rates Undercounted Due to Overdose Misclassification
Up to 30% of accidental drug overdoses may be suicides, according to a new commentary in Injury Prevention. Researchers propose a new metric to fix the undercount.
Study Inverts Dunning-Kruger: High Performers Are Most Overconfident
A new study in Psychological Review finds the Dunning-Kruger effect is a statistical artifact — and when corrected, top performers show the greatest overconfidence.
Weak Bone Density Linked to Faster Cognitive Decline
Johns Hopkins researchers found low spinal bone density predicts faster cognitive decline and white matter injury, pointing to shared metabolic aging drivers.
3-Brain-Region Circuit Found to Consolidate Memory During Sleep
A human intracranial study shows sleep memory consolidation requires coordinated activity across the orbitofrontal cortex, thalamus, and hippocampus — and epileptic spikes break it.
