AI Uncovers Hidden Stress Damage in the Body

Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body.

Genes Behind Dog Behaviors Also Shape Human Emotions

Researchers analyzed the genomes and behavioral profiles of 1,300 golden retrievers and found that several behavioral traits—such as trainability, fear of strangers, and aggression toward other dogs—are shaped by specific genetic variants. Remarkably, a dozen of these same genes also influence emotional and cognitive traits in humans, revealing shared biological roots across species.

Genetics Point to a New Type of Suicide Risk

New research shows that many people who die by suicide without prior suicidal thoughts or behaviors are not simply “missed cases”—they may have an entirely different underlying risk profile. Genetic analyses of more than 2,700 deaths revealed that these individuals carry fewer genetic risk factors for major psychiatric conditions compared to those with known suicidality.

Stress-Like Behaviors Traced to a Single ATP Circuit in the Brain

New research reveals that reduced ATP signaling in the hippocampus plays a causal role in both depression- and anxiety-like behaviors. In stressed male mice, ATP levels and the ATP-releasing protein connexin 43 were markedly lower.

Psychedelic ‘Ego Death’ Tied to a Collapse in Alpha Brain Waves

A new study using DMT as a scientific tool reveals how psychedelics alter the brain’s alpha-wave dynamics and weaken our sense of self. The researchers found that DMT pushes the brain away from its usual “critical” balance between chaos and order, a state believed to be essential for coherent self-awareness over time.

AI Reveals Lions Don’t Just Roar, They Have a Second Call

A new study reveals African lions produce two types of roars, overturning long-held assumptions and opening the door to more precise wildlife monitoring. Using machine learning, researchers automatically distinguished between full-throated and newly identified intermediary roars with over 95% accuracy, eliminating much of the human bias in vocal identification.

What Triggers Tantrums? Sensory Overload May Be To Blame

New research reveals a distinct brain activity signature in children who become overwhelmed by sensory input such as noise, touch, or bright lights. Using functional MRI, scientists found that overly sensitive children show reduced activation in outward-facing sensory and motor networks while increasing activation in inward-focused networks tied to cognition and impulse control.

Brain Circuit That Forces Behavior Into “Repeat Mode” Identified

A new study has identified a specific brain circuit that can push behavior into a compulsive “repeat mode,” forcing mice to continue digging and sniffing even when rewards are available. The circuit links the nucleus accumbens to the hypothalamus and then to the lateral habenula, a region involved in processing negative experiences.

Screen Time in Tweens Predicts ADHD, Slower Brain Growth

A large, two-year study of nearly 12,000 children found that higher screen time at ages 9–10 predicts an increase in ADHD symptoms, independent of a child’s starting symptom level. Brain imaging revealed that heavy screen use is associated with smaller cortical volume and disrupted development in regions critical for attention, cognition, and reward processing.

Thrill Fatigue: How Dopamine Devalues Repeated Rewards

New research shows that the same dopamine receptor mechanism responsible for drug addiction also governs the natural decline in motivation when we repeat rewarding behaviors. By studying male fruit flies, researchers found that dopamine acting through the D2 receptor promotes persistence during mating, but repeated experiences cause these receptors to desensitize.

AI Interviews Outperform Standard Mental Health Rating Scales

A new study demonstrates that an AI assistant can conduct psychiatric assessment interviews with greater diagnostic accuracy than widely used mental health rating scales. In a sample of 303 participants with confirmed psychiatric conditions, the AI assistant Alba provided DSM-based diagnostic suggestions after a brief conversational interview, outperforming rating scales in eight of nine disorders.

Unexpected Superhero Cameos Make People Kinder

A new behavioral study demonstrates that sudden, unexpected events can significantly increase altruistic behavior in everyday environments. When a person dressed as Batman appeared on a Milan subway, passengers were nearly twice as likely to give up their seats to a pregnant woman compared to the normal routine condition.
