Friendship Chemistry: How Oxytocin Shapes Who We Bond With

New research on prairie voles shows that while oxytocin is not strictly necessary for friendship, it plays a vital role in quickly forming and maintaining strong social bonds. Voles lacking oxytocin receptors took up to a week to develop preferences for peers that normal voles formed in a day, and they often failed to prioritize known companions in group settings.

Microglia Transplant Restores Function in Degenerative Brain Disease

Scientists have developed a targeted brain cell transplant that could transform treatment for Tay-Sachs and Sandhoff diseases. By depleting diseased microglia and replacing them with healthy donor precursor cells, researchers restored crucial enzyme function in the brain and dramatically extended lifespan in mice.

How Kids Learn What Emotions Really Mean

A new study reveals that children’s ability to understand emotions develops through a cognitive shift between ages 5 and 10. While younger kids perceive emotional expressions instinctively through visual cues, older children increasingly depend on conceptual knowledge to grasp emotional nuance.

Leptin, Not Just Insulin, May Hold the Key to Diabetes Treatment

A decade after an overlooked discovery, researchers now confirm that the hormone leptin can reverse diabetic ketoacidosis (DKA) even without insulin. The brain, misled by low leptin into thinking the body lacks fuel, triggers a metabolic emergency — a core process in DKA.

New Drug Targets Brain Glial Cells to Reverse PTSD Symptoms

A new study reveals that astrocyte-derived GABA, not neuronal activity, plays a central role in PTSD by impairing the brain’s ability to extinguish traumatic memories. Researchers found this excess GABA originates from the enzyme MAOB in astrocytes and disrupts fear regulation in the medial prefrontal cortex.

Oxytocin May Treat the Social Deficits of Psychopathy

Psychopathy impairs the ability to recognize and respond appropriately to emotional facial expressions, often disrupting empathy and social behavior. A new review explores whether oxytocin—a neuropeptide known to promote social bonding—can help compensate for these deficits.

Online Hate Speech Resembles Mental Health Disorder Language

A new study using AI tools found that posts in online hate speech communities closely resemble the speech patterns seen in forums for certain personality disorders. While it doesn’t imply that people with psychiatric diagnoses are more prone to hate, the overlap suggests that online hate speech may cultivate traits like low empathy and emotional instability.

How Cool Touch Travels From Skin to Brain

A groundbreaking study has mapped the full neural circuit that carries cool temperature signals from the skin to the brain. The pathway begins with molecular sensors in the skin, which activate neurons that send signals to the spinal cord, where the message is amplified before reaching the brain.

Old Injuries Rewire the Brain to Feel Fear and Pain Forever

A new study reveals that even after healing, injuries can leave behind a hypersensitive nervous system that overreacts to future stress. Mice previously injured showed intense fear and renewed pain when exposed to a predator scent, despite no new harm.

How the Brain Decides to Flee or Freeze

A new study reveals how evolution fine-tunes instinctive fear responses by tweaking a key neural switch deep in the brain. Comparing two deer-mouse species, researchers found that forest-dwelling mice have hypersensitive escape circuits, while open-field mice are more likely to freeze.

Genetic Link Between Cannabis Use Disorder and Mental Health

A large genetic study reveals that cannabis use disorder (CanUD) is strongly linked to increased risk for multiple psychiatric disorders, including depression, PTSD, ADHD, and schizophrenia. By analyzing global and local genetic correlations, colocalization, Mendelian randomization, and structural equation modeling, researchers showed CanUD has distinct genetic signatures compared to casual cannabis use.

Motion is Your Signature: How Dynamic Cues Reveal Identity

New research highlights the critical role of dynamic motion in recognizing familiar people, beyond static facial or body features. Faces, voices, and body movements each carry unique, idiosyncratic motion patterns — or “dynamic fingerprints” — that help perceivers identify individuals, even under challenging conditions.
