Engineered Protein Reveals Hidden Incoming Signals Between Neurons

Researchers have engineered a next-generation glutamate sensor, iGluSnFR4, capable of detecting the faintest incoming synaptic signals between neurons—signals that, until now, have been nearly impossible to record in living brain tissue. By capturing these whisper-quiet inputs, scientists can finally observe how neurons weigh thousands of glutamate messages and transform them into an electrical output, the core computation behind memory, learning, and emotion.

This shows AI representations of brain scans.

fMRI Signals Often Misread Neural Activity

fMRI signals don’t always match the brain’s true activity levels, overturning a core assumption used in tens of thousands of studies. In about 40% of cases, an increased fMRI signal appeared in regions where neural activity was actually reduced, while decreased signals sometimes showed up in areas with heightened activity.

AI Turns Simple EEG Scans Into Accurate Dementia Detectors

New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.

AI-Powered Bionic Hand Restores Natural, Intuitive Grasping Ability

A new study shows that integrating artificial intelligence with advanced proximity and pressure sensors allows a commercial bionic hand to grasp objects in a natural, intuitive way—reducing cognitive effort for amputees. By training an artificial neural network on grasping postures, each finger could independently “see” objects and automatically move into the correct position, improving grip security and precision.

AI Is Changing the Way Humans Grieve, Remember, and Face Death

Generative artificial intelligence is quietly reshaping how humans process grief, remembrance, and mortality. Digital reconstructions of the deceased may offer comfort, but they also risk blurring the natural boundary between presence and absence.

AI Watches Pianists and Reconstructs Their Muscle Signals

Researchers developed an AI system that can reconstruct fine hand muscle activity using only standard video footage. Traditionally, this type of measurement required intrusive electrodes attached to the skin, but the new method eliminates that need entirely.

Neural Ultrasound Boosts Learning in 60 Seconds

Researchers have successfully altered human reward learning using non-invasive transcranial ultrasound stimulation directed at a deep brain structure linked to motivation. After brief stimulation, participants learned faster from positive feedback and repeated rewarding choices more consistently.

Thought Begins Before We’re Born

New research using human brain organoids shows that early neural activity follows structured, time-based patterns long before sensory experience begins. These findings suggest the human brain comes preconfigured with a built-in “operating system” for organizing information, rather than relying solely on external input to form its circuits.

AI Interviews Outperform Standard Mental Health Rating Scales

A new study demonstrates that an AI assistant can conduct psychiatric assessment interviews with greater diagnostic accuracy than widely used mental health rating scales. In a sample of 303 participants with confirmed psychiatric conditions, the AI assistant Alba provided DSM-based diagnostic suggestions after a brief conversational interview, outperforming rating scales in eight of nine disorders.

Ultra-Thin Finger Patch Recreates Touch With Human-Level Precision

Engineers have created VoxeLite, the first wearable haptic device capable of matching the sensitivity of the human fingertip. Built as a paper-thin, flexible bandage for the finger, it uses high-density electroadhesive “pixels of touch” to recreate fine textures and directional cues with lifelike accuracy.

Deep Brain Stimulation Promising for Severe, Resistant Depression

A new clinical trial shows that deep brain stimulation (DBS) improved symptoms in half of adults with treatment-resistant depression, with one-third reaching remission. Researchers found that theta-frequency brain activity in the bed nucleus of the stria terminalis (BNST) predicted how well each patient responded.

Animal-Free Brain Tissue Breakthrough Could Transform Drug Testing

Researchers have created functional brain-like tissue without relying on any animal-derived materials, marking a major step toward more ethical and reproducible neurological research. By transforming a chemically inert polymer (PEG) into a porous, maze-like scaffold, scientists enabled donor brain cells to organize into active neural networks.
