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.

One in Two Americans Have Neurological Disorders

A comprehensive national analysis shows that over 180 million Americans—more than half the U.S. population—are living with a neurological disease or disorder. These conditions span the lifespan, from neurodevelopmental disorders to migraines to age-related diseases such as Parkinson’s and Alzheimer’s.

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.

Genetics Plus Heart Health Markers Sharpen Dementia Risk

New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.

Supplement Shows Promise in Blocking Amyloid in Alzheimer’s

A new study shows that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β aggregation in Alzheimer’s disease models. Researchers found that arginine not only prevented Aβ42 from clumping but also reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations.

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.
