Oxidative Stress May Drive Repetitive Behaviors Linked to Autism, OCD

A new study shows that oxidative stress—an imbalance between damaging molecules and antioxidants—may contribute to repetitive behaviors observed in mice, similar to those seen in autism spectrum disorder and schizophrenia. Researchers found that higher levels of oxidative stress biomarkers, including glutathione and specific proteins, were linked to more severe stereotypies in young mice.

Early Trauma Hardwires the Brain for Aggression and Self-Harm

A new study reveals that aggression and self-harm share a biological foundation in the brain’s response to early-life trauma. Researchers discovered that trauma increases activity in calcium channels within a neural circuit connecting the nucleus reuniens and hippocampus, amplifying pain processing and impulsive behavior.

Your Neighborhood Could Influence Your Risk of Dementia

Researchers found that living in a socioeconomically deprived neighborhood can harm brain health as early as midlife. People from these areas showed more signs of small-vessel brain damage, slower thinking skills, and poorer control of lifestyle factors such as blood pressure, obesity, and sleep.

Brain’s Immune Cells Found to Protect Against Alzheimer’s Damage

Researchers have uncovered how the brain’s immune cells, called microglia, can act as protectors rather than destroyers in Alzheimer’s disease. By lowering the immune regulator PU.1, microglia began expressing lymphoid-like receptors that reduced inflammation and preserved cognitive function in mouse models.

Antibiotic Doxycycline May Cut Schizophrenia Risk

A large population-based study suggests that doxycycline, a common antibiotic, may reduce the risk of schizophrenia when prescribed to adolescents receiving mental health care. Researchers analyzed data from more than 56,000 young patients and found that those who took doxycycline had a 30–35% lower chance of developing schizophrenia later in life.

3D Brain Map Reveals How Inflammation Reawakens Developmental Genes

Researchers have developed the most detailed molecular map yet of how the brain develops and reacts to inflammation, revealing that disease processes can “reawaken” genes from early life. Using a new spatial tri-omics technique, the team tracked how gene activity, epigenetic changes, and protein production interact in specific brain regions.

AI Creates the Most Detailed 3D Map of the Human Brain Ever Made

A new AI-powered atlas called NextBrain allows researchers to visualize the human brain in unprecedented detail, down to hundreds of tiny subregions previously invisible on MRI scans. Built from 10,000 microscopic slices of post-mortem brains and aligned with AI, the atlas precisely maps 333 brain regions in 3D.

AI Can Spot Lies, But Not as Well as Humans Can

A large-scale study tested whether AI personas can detect when humans are lying—and found that while AI can sometimes spot deception, it’s still far from trustworthy. Across 12 experiments involving 19,000 AI participants, the systems performed inconsistently, showing a strong bias toward identifying lies rather than truths.

AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health

For the first time, scientists have mapped the genetic architecture of the brain’s communication bridge—the corpus callosum—using AI and MRI data from over 50,000 people. The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.

BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Your Brain Knows a Viral Message Before You Do

A large-scale brain imaging analysis reveals that our brains can forecast what kinds of messages will go viral. Researchers found that persuasive messages consistently activate brain regions associated with reward, empathy, and social understanding, predicting both personal preferences and public appeal. Interestingly, while emotional brain activity predicted message success in larger audiences, it did not in individuals who were scanned.

Antioxidant Defense System in the Brain Discovered

A new study identifies biliverdin reductase A (BVRA) as a crucial enzyme defending neurons from oxidative stress, acting independently of its traditional role in bilirubin production. Using genetically modified mice, researchers found that BVRA binds directly to NRF2, a master regulator of antioxidant defense, ensuring the activation of protective genes that maintain cellular health.
