Different Autism Genes, Same Brain Signature
Summary: New research shows that different genetic forms of autism may produce a shared brain activity pattern, revealing a potential common neural signature despite distinct genetic origins. Using brain-wide recordings…
Genetic Sensitivity to Environment May Shape Mental Health Traits
Summary: A large international study of over 21,000 identical twins has identified genetic variants that influence how individuals respond to life experiences, affecting traits such as anxiety, depression, and autistic…
Dormant Stem Cells May Hold Key to Restoring Sense of Smell
Summary: Researchers have created a 3D mouse organoid model to study how neurons in the nose regenerate, revealing that a type of stem cell once considered dormant may be crucial…
Shared Genetic Signatures Found Across Psychiatric Disorders
Summary: Researchers have uncovered shared biological mechanisms across major psychiatric disorders by analyzing postmortem brain samples from the dorsolateral prefrontal cortex. Instead of looking at gene expression broadly, they zoomed…
Blood Test Identifies Depression Risk in Teenagers
Summary: Researchers have identified nine blood-based microRNAs that are elevated in teens diagnosed with depression, offering a potential biomarker for early detection. These molecules, absent in adult depression, may signal…
Clues in Spinal Fluid Could Unlock Early FTD Diagnosis
Summary: Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified…
Tiny Gene Fragment Key to Memory Revealed
Summary: Researchers have discovered that a nine–amino acid microexon spliced into the DAAM1 gene is critical for memory formation, functioning exclusively in neurons. Deleting this microexon in mice resulted in…
Bigger Brains and Strong Immunity Linked to Longer Lifespans
Summary: New research reveals that mammals with larger brains and more robust immune systems tend to live longer lives. By studying 46 species, scientists found a clear link between maximum…
