Choose Your Battles: Identity Shapes Displaced Aggression

Displaced aggression—redirecting frustration onto an uninvolved target—has now been studied in mice, revealing that identity and social history play key roles in shaping aggressive behavior. Male mice primed by seeing a rival behind a barrier showed increased aggression only when the rival was unfamiliar or lacked a clear social hierarchy.

How PTSD Disrupts Brain Cell Communication

A new study has examined brains affected by PTSD at the single-cell level, uncovering distinct genetic alterations that may drive the disorder. Researchers focused on the dorsolateral prefrontal cortex, a brain region tied to emotional regulation, analyzing individual cell nuclei to map communication differences across PTSD, major depression, and control brains. They found impaired signaling in inhibitory neurons in PTSD, potentially explaining hyperarousal symptoms, and opposing patterns of microglial activity in PTSD versus depression. Vascular endothelial cells in PTSD brains also showed signs of dysfunction, possibly increasing stress hormone exposure.

Why Some People Struggle to Recognize Faces of Other Races

New research reveals that some individuals may experience selective difficulty recognizing faces from racial groups different from their own, a phenomenon known as category-selective face blindness. While general face blindness (prosopagnosia) is well-documented, this study shows that many people perform well with own-race faces but poorly with others.

Facial Expressions Reveal Hidden Cognitive States

New research shows that facial expressions can reveal internal cognitive states, accurately predicting task performance across both macaques and mice. By analyzing facial features during a foraging task in a virtual reality setup, researchers identified patterns linked to motivation, focus, and responsiveness.

Wellbeing May Help Protect Memory in Middle Age

A new 16-year study of over 10,000 adults finds that higher wellbeing is linked to better memory performance in middle age. Researchers tracked participants' psychological wellbeing and memory recall, finding that those with higher life satisfaction were more likely to retain stronger cognitive function over time.

Ketamine Plus Therapy Offers Lasting Relief for Severe Depression

A first-of-its-kind clinical trial shows that ketamine treatment for severe, treatment-resistant depression is significantly more effective when paired with psychotherapy and supportive environments. Patients who underwent this combined treatment reported a 30% drop in depression symptoms, with reduced anxiety and suicidal thoughts lasting at least eight weeks.

Hope Outshines Happiness as Key to Life’s Meaning

Hope isn’t just about wishful thinking—it’s a unique emotional experience that may be more essential to well-being than happiness or gratitude. A new study shows that hope stands out among positive emotions as the most consistent predictor of a meaningful life.

AI Generates Relatable Empathy Experiences

Researchers have developed an AI tool called EmoSync that boosts empathy by tailoring emotional analogies to each user’s personality and life experiences. Unlike traditional empathy tech that assumes uniform emotional responses, EmoSync uses a large language model (LLM) to map personal traits and generate custom scenarios that resonate more deeply. In a study of over 100 participants, those using EmoSync showed significantly better understanding of others’ emotions than with conventional methods. The technology represents a new frontier in emotion-aware AI, aiming to foster authentic interpersonal understanding in complex social environments.

Addictive Screen Use, Not Time, Tied to Teen Suicide Risk

A major new study reveals that teens who develop compulsive patterns of digital use are at higher risk of suicidal thoughts, attempts, and mental health issues. Unlike total screen time, it’s the addictive nature of use—such as distress when not online or using screens to escape—that most strongly predicts poor outcomes.

Multiple Brain Profiles May Underlie the Same Depressive Symptoms

A new study reveals that the same clinical signs of depression may stem from different brain profiles, highlighting both one-to-one and many-to-one brain-symptom mappings. Using brain imaging data from the UK Biobank, researchers found that even when patients experience similar symptoms, their underlying neurobiology may differ significantly.

Childhood Emotion Struggles Linked to Teen Anxiety and Depression

Children who have trouble managing their emotions at age seven are more likely to experience anxiety and depression during their teenage years, a new study finds. Researchers analyzed data from the UK Millennium Cohort Study, tracking emotional development and mental health from childhood to age 17.

Gut Microbiome May Influence Bipolar Medication Response

A new review has examined how bipolar disorder medications interact with the gut microbiome, revealing important links between treatment response and gut microbial composition. Researchers analyzed 12 studies comparing the microbiomes of treated, untreated, and healthy individuals.
