Why Humans Adapt Faster Than AI

Humans excel at adapting to new situations, while machines often stumble. A new interdisciplinary study reveals that the root lies in how humans and AI approach “generalization,” the process of transferring knowledge to new problems.

Green Mediterranean Diet Slows Brain Aging

A large-scale dietary trial has shown that a green-Mediterranean diet can slow brain aging by altering key blood proteins linked to neurodegeneration. Using MRI scans and proteomic profiling, researchers tracked nearly 300 participants over 18 months and found that diet significantly shaped the brain age gap.

Boosting Protein Keeps Neurons Healthy and Extend Lifespan

Scientists have identified a new therapeutic strategy for neurodegenerative diseases by boosting a protein called PI31, which ensures proteasomes reach synapses to clear protein waste. In fruit flies and mice, restoring PI31 prevented neuronal degeneration, reversed motor defects, and even extended lifespan nearly fourfold.

Illusion-Making Neurons Show How the Brain Constructs Reality

Scientists have discovered specialized IC-encoder neurons that make the brain “see” illusions, such as squares or triangles that aren’t truly there. These neurons receive top-down instructions from higher brain areas and then fill in missing contours in the visual cortex, actively constructing what we perceive.

This shows the outline of two people and brains.

Brain Circuits Show Why Friends’ Lies Are Easier to Believe

Researchers explored how people process deception from friends versus strangers, using brain imaging to study decision-making in gain and loss contexts. Volunteers were more likely to believe lies in situations promising rewards, with brain activity highlighting circuits for risk, reward, and intention.

Nanoplastics Disrupt Brain Energy, Threatening Memory Function

Scientists have uncovered a mechanism by which nanoplastics impair brain energy metabolism, offering new clues into environmental contributions to neurodegeneration. The particles disrupted mitochondrial electron transfer and reduced energy production in both general and synaptic mitochondria.

Simple Hair Test May Spot Mental Health Risks in Kids

Long-term stress, measured through hair cortisol, may help predict mental health risks in children living with chronic physical illnesses. In a four-year study of 244 children, researchers found that persistently high cortisol levels were strongly linked to anxiety, depression, and behavioral difficulties.

PET Tracer Maps Synapse Loss After Spinal Cord Injury

Researchers developed a new PET tracer capable of measuring synapse loss after spinal cord injury, offering insights into both spinal and brain changes. In rat models, the tracer revealed significant synaptic reductions at the injury site and in distant brain regions, highlighting how widespread the effects of injury can be.

How the Brain Uses Objects to Find Direction

Scientists discovered how the brain uses objects to anchor our sense of direction, solving part of the mystery of spatial navigation. Experiments in mice showed that cells in the postsubiculum fired strongly when facing an object, while cells for other directions were suppressed, sharpening orientation.

Defective Exosome Production Linked to Alzheimer’s Gene Mutation

New research reveals that a gene mutation tied to Alzheimer’s disease disrupts the production of exosomes, tiny cellular particles essential for communication between brain cells. Cells with a defective SORLA protein produced about 30% fewer exosomes, and those exosomes were up to 50% less effective at supporting cell growth.
