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.

Language Emerged From Many Roots, Not Just One

A new framework argues that human language did not arise from a single evolutionary leap but from the convergence of many biological abilities and cultural processes. The authors highlight how speech learning, grammar formation, and social cooperation evolved along different paths before merging into the complex communication we use today.

The Brain Has a Dance Mode, And AI Just Mapped It

A team of researchers used a massive dance video dataset and advanced AI models to map how the human brain interprets dance, revealing striking differences between experts and nonexperts. By pairing fMRI recordings with AI-derived cross-modal features, they found that higher-order brain regions outperform simple motion or sound cues when processing choreography.

Brain Releases Hidden Kinase to Supercharge Pain and Learning

New research reveals that neurons release a little-understood extracellular kinase called VLK to strengthen synaptic connections, providing a missing piece in how the nervous system adapts during learning and pain. The kinase phosphorylates EphB receptors outside the cell, which recruits NMDA receptors and amplifies synaptic signaling.

Shocking Disparities: Women Face Higher Risk of ECT

A large international survey of 858 electroconvulsive therapy recipients found that women are twice as likely as men to receive ECT and experience more adverse effects. Women reported higher rates of memory loss, greater feelings of coercion, and more harmful emotional outcomes, often describing the treatment as retraumatizing.

Ultra-Thin Finger Patch Recreates Touch With Human-Level Precision

Engineers have created VoxeLite, the first wearable haptic device capable of matching the sensitivity of the human fingertip. Built as a paper-thin, flexible bandage for the finger, it uses high-density electroadhesive “pixels of touch” to recreate fine textures and directional cues with lifelike accuracy.

Cannabis Blunts Alcohol Cravings

A randomized, placebo-controlled trial shows that cannabis with active THC reduces immediate alcohol cravings and lowers drinking levels in heavy-drinking young adults. After smoking THC, participants not only drank less, they waited longer before taking the first sip and reported lower urges to drink.

Restoring Vision: Temporary Retinal Silencing Reverses Amblyopia

A new study in mice shows that briefly anesthetizing the retina of the weaker eye can restore its neural influence in the adult visual cortex. The treatment activates a specific burst-firing mode in thalamic neurons, a developmental mechanism that reopens plasticity even after the usual critical period has closed.
