Preconception Maternal Trauma Doubles Schizophrenia Risk

A new study demonstrates that preconception trauma carries a heavy transgenerational psychiatric burden. By tracking decades of health registry data from over 30,000 individuals, the team unmasked that children born to mothers who were older than age five during Nazi persecutions face an over two-fold increase in schizophrenia risk, highlighting maternal-specific epigenetic or intrauterine transmission paths.

Single Cocaine Exposure Leaves a Long-Lasting Genetic Scar

A new study reveals that a single exposure to cocaine induces long-lasting structural changes within dopaminergic neurons in the midbrain's ventral tegmental area.

Astrocytes Actively Dictate Long-Term Memory Persistence

By leveraging ankyrin-2 (Ank2) to regulate BDNF/TrkB.T1 calcium signaling, astrocytes undergo structural remodeling to physically encapsulate and stabilize memory-storing engram neurons, a mechanism validated through a novel optogenetic tool called Opto-T1.

Maternal High-Fructose Diets Epigenetically Scar Fetal Brain Cells

A maternal diet high in fructose corn syrup programs permanent learning and memory deficits in adult offspring. The mechanism is driven by lasting epigenetic imprints on fetal neural stem cells that silence neurogenesis genes into adulthood, establishing a direct "biological memory" of prenatal maternal nutrition.

Optogenetics Restores Motor Learning in Huntington’s

Optogenetically activating underactive VIP inhibitory neurons in the motor cortex completely restores normal circuit activity and motor learning in Huntington’s disease models, with therapeutic benefits persisting long after stimulation ends.

Researchers Grow Rare Eye Vessel Cells to Halt Vision Loss

A new study demonstrates the first successful generation of retinal endothelial cells from induced pluripotent stem cells (iPSCs). When tested in vitro, the cells accurately modeled the tissue degradation of diabetic retinopathy, and when injected in vivo, they successfully integrated to regenerate damaged retinal blood vessels and restore function.

Nanosensor Separates Autism From Intellectual Disability

Scientists demonstrates that a carbon-fiber nanosensor can differentiate Autism Spectrum Disorder from Intellectual Disability by measuring real-time nitric oxide production in undifferentiated patient stem cells, even when both conditions share identical genetic mutations.

Brain Tissue Patterns and Genetics Drive MS Progression

A comprehensive study of 287 MS brain tissue donors from the Netherlands Brain Bank demonstrates that multiple sclerosis progression variability is driven by specific pathological features, such as broad rim lesions and myelin repair failures, which are directly modulated by an individual's genetic background.

Arthritis Drug Found to Reduce Excessive Alcohol Use

An FDA-approved rheumatoid arthritis drug targeting the IL-6 receptor significantly reduces excessive alcohol consumption in alcohol-dependent female mice. The treatment functions by blocking neuroinflammatory pathways that suppress the GABAergic braking system in the central amygdala, a mechanism corroborated by elevated IL-6 expression found in postmortem human AUD brain tissue.

Arc Protein Found to Spread Toxic Tau in Alzheimer’s

The native brain protein Arc mediates the intercellular transmission of toxic Tau via extracellular vesicles in Alzheimer's disease. While Arc helps sick neurons survive longer by expelling toxic Tau aggregates, it simultaneously promotes the spread of pathology to healthy cells, identifying the extracellular space as a prime "mid-flight" therapeutic target.

Overcoming Endothelial Sorting to Cure Glioblastoma

Researchers present a shift in neuro-nanomedicine, reframing the "protein corona", the layer of blood proteins that coat nanoparticles, as a programmable, five-stage navigation interface capable of guiding therapeutics across the blood-brain barrier via receptor-mediated transcytosis.
