Evolution of Human Brain May Explain High Autism Rates

Summary: A new study suggests that autism may be linked to the rapid evolution of brain cell types unique to humans. Researchers found that outer-layer neurons in the human brain…

Brain Cells Behind Depression Identified

Summary: Researchers analyzing post-mortem brain tissue found two cell types altered in people with depression: excitatory neurons that regulate mood and stress, and microglia that manage inflammation. The findings highlight…

Eight New Genes Linked to Schizophrenia Revealed

Summary: The largest exome-sequencing study of schizophrenia to date has uncovered eight new genes tied to the disorder. Two genes, STAG1 and ZNF136, were strongly implicated, while six others showed…

Bipolar Mood Shifts Linked to Insulin Signaling in the Pancreas

Summary: A new study uncovers a pancreas–hippocampus feedback loop that may help explain mood swings in bipolar disorder. Using patient-derived pancreatic islets, researchers found reduced insulin secretion linked to elevated…

First “Microwave Brain” Chip Merges Ultrafast Data and Wireless Signals

Summary: Researchers have built the first “microwave brain” chip capable of processing both ultrafast data and wireless communication signals at once. By harnessing analog, nonlinear microwave physics instead of conventional…

Brain Reward Signals Blunted by Genetic Depression Risk

Key Questions Answered Q: How does genetic risk for depression affect the brain?A: Young adults with a higher genetic predisposition to depression showed reduced brain activity in key areas linked…

DNA Reveals Multiple Sclerosis Risk Before Symptoms Begin

Q: What is this study trying to discover about MS?A: Researchers aim to understand how genetic risk factors and immune response to the Epstein-Barr virus may interact to trigger multiple…

Could Mental Illness Begin Before You’re Born?

Key Questions Answered: Q: When do genes linked to mental illness start affecting the brain?A: Many genes associated with neuropsychiatric and neurodegenerative diseases are active during the earliest stages of…

Most Mental Illnesses Arise Without Family History

Summary: A massive Danish study shows that most mental illnesses—like schizophrenia, bipolar disorder, and depression—occur in people with no close family history of the condition. Analyzing data from over 3…

Genetic Link Between Cannabis Use Disorder and Mental Health
