Boosting Sleep Ripples Helps Preserve Memories Normally Forgotten

A new study shows that precisely manipulating brain activity during sleep can help mice retain memories that would normally fade, offering a potential pathway for treating memory loss conditions. Researchers identified a specific sleep-related pattern—large sharp-wave ripples—that signals when new experiences are being transferred from the hippocampus to the neocortex for long-term storage. By boosting these ripples at just the right moment using optogenetics, scientists enabled mice to remember brief encounters they would typically forget.

Stress Levels Predict Cannabis Use

New research shows that rats with naturally higher baseline stress hormone levels are significantly more likely to self-administer cannabis vapor. Over several weeks, rats were allowed to nose-poke for cannabis, and those with elevated corticosterone displayed the strongest drug-seeking behavior.

Losing Myelin Scrambles the Brain’s Sensory Signals

New research reveals that even a small loss of myelin—the protective coating around neurons—can severely disrupt how the brain sends and interprets sensory information. Studying corticothalamic circuits in mice, scientists found that when the first segment of myelin closest to the neuron’s cell body was degraded, nerve signals slowed and lost their crucial “first wave,” altering how sensory information was encoded.

Anti-Inflammatory Treatments Show Promise for Depression

A new analysis shows that anti-inflammatory medications may help reduce symptoms for a subset of people with depression who also have chronic, low-grade inflammation. By reviewing randomized controlled trials that specifically enrolled individuals with elevated inflammatory markers, researchers found that anti-inflammatory treatments significantly reduced both overall depressive symptoms and anhedonia.

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.

Nicotine Withdrawal Makes Smokers More Sensitive to Pain

A new study shows that abstinent smokers experience heightened pain sensitivity linked to altered activity in specific brain regions. Compared to nonsmokers, abstinent smokers required more postoperative pain relief—especially opioids—and their pain sensitivity increased the longer they remained nicotine-free.

Blocking a Key Protein Greatly Reduces Alzheimer’s Damage

New findings show that removing Centaurin-α1, a protein elevated in Alzheimer’s disease, significantly reduces inflammation, plaque buildup, and cognitive deficits in a well-established mouse model. Eliminating this protein normalized several brain pathways, protected neural connections in the hippocampus, and improved spatial learning.

Mutation in Key Enzyme Triggers Ferroptosis and Childhood Dementia

Researchers have identified how a single mutation in the GPX4 enzyme causes neurons to undergo ferroptosis, leading to severe early-onset dementia. The study provides the first molecular evidence that ferroptosis can directly drive neurodegeneration in the human brain.

Fungal Molecule Shows Promise Against Brain Cancer

For the first time, chemists have fully synthesized verticillin A, a notoriously complex fungal molecule with striking anticancer potential. The molecule’s fragile structure required a complete rethinking of its synthetic sequence, enabling researchers to not only recreate it but design more stable and potent derivatives.

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.

Brain Uses AI-Like Computations for Language

The human brain processes spoken language in a step-by-step sequence that closely matches how large language models transform text. Using electrocorticography recordings from people listening to a podcast, researchers found that early brain responses aligned with early AI layers, while deeper layers corresponded to later neural activity in regions such as Broca’s area.

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.

AI Uncovers Hidden Stress Damage in the Body

Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body.

Positive Imagining Changes the Brain in Seconds

Vividly imagining a positive interaction with someone can increase how much you like them — and even alter how your brain stores information about that person. During imagined encounters, participants developed stronger preferences, and brain scans revealed activity patterns similar to those seen when people learn from real rewarding experiences.

Reading Habits Predict Hidden Biases Toward Autism

A new study shows that the newspapers people read are strong predictors of their automatic, unconscious biases toward autism—even after accounting for age, education, political views, and personal experience. Readers of right-leaning tabloid outlets showed more negative automatic biases, reflecting the more stereotyped and less frequent coverage of autism in these publications.

PTSD Linked to Accelerated Brain Aging

A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.

Warmth and Hugging Strengthen the Feeling of Being You

Changes in skin temperature play a key role in how strongly we experience our bodies as our own. Thermoception influences emotion, identity, and mental health by acting as a direct “skin-to-brain” pathway supporting bodily self-awareness.
