Most People Overestimate Their Moral Courage Under Pressure

A new study reveals that most people believe they would defy immoral orders from authority figures more than others would. This cognitive bias, known as the “better-than-average effect,” causes individuals to underestimate their own susceptibility to social pressure.

Different Autism Genes, Same Brain Signature

New research shows that different genetic forms of autism may produce a shared brain activity pattern, revealing a potential common neural signature despite distinct genetic origins. Using brain-wide recordings in preclinical models, scientists observed that autism-linked mutations affected how expectations are updated during decision-making.

No Link Found Between Preterm Siblings and Child Behavior Issues

A large-scale European study found no evidence that having a sibling born preterm leads to more behavioral problems in children born at term. Researchers analyzed data from over 65,000 children and found no significant differences in behavior between children with preterm versus term-born siblings.

Robot Yawns Spark Contagious Yawning in Chimps

Chimpanzees have been observed yawning and lying down after seeing a humanoid android mimic a yawning facial expression, indicating contagious yawning triggered by an artificial agent. This study is the first to show yawn contagion in response to an inanimate model, suggesting that yawns may serve as a rest cue in addition to a social reflex.

AI Links Early Life Risks to Behavioral Challenges at Age Five

A new study reveals that emotional and behavioral difficulties in five-year-old children can be predicted using prenatal and early-life risk factors, including maternal smoking, low birth weight, and lack of breastfeeding. Researchers used AI to analyze data from nearly 6,000 UK children, uncovering gender-specific vulnerabilities—boys were more impacted by smoking during pregnancy, while girls were more affected by early fussiness.

Tiny Genetic Code Disruption Alters Brain Wiring and Behavior

A small genetic sequence called mini-exon B plays a surprisingly crucial role in how neurons form synaptic connections, according to new research. Scientists found that deleting this four–amino acid segment from a synapse-building protein, PTPδ, disrupted neural activity and led to anxiety-like behaviors in mice.

Modeling Human Behavior with Math

A new study shows that mathematical models can shape human decisions more effectively than traditional psychological strategies. Researchers introduced “choice engineering,” a data-driven alternative to “choice architecture,” which relies on heuristics and intuition. In a global academic challenge, models like CATIE—designed to reflect real behavioral trends—outperformed both intuitive strategies and standard machine learning tools.

Inflammation Triggers Repetitive Behaviors in ASD and OCD

New research reveals that chronic brain inflammation can directly lead to repetitive behaviors, often seen in conditions like autism spectrum disorder (ASD) and obsessive-compulsive disorder (OCD). In mice with a mutated NLRP3 gene, inflammation activated microglia to release IL-1β, overstimulating NMDA glutamate receptors responsible for excitatory brain signals.

Hidden Patterns Shape Animal Behavior Across Species

Despite vast ecological differences, animals from meerkats to hyenas appear to follow a shared behavioral architecture in how they switch between activities. By tracking movement patterns with accelerometers and using machine learning, researchers discovered that the longer an animal stays in one behavior—like resting or foraging—the less likely it is to switch, a pattern known as a “decreasing hazard function.”

Astrocytes Control Behavior Through Slow Brain Signaling

Astrocytes, once thought to be mere support cells, are now shown to play a leading role in regulating behavior by modulating neuronal activity through slow biochemical circuits. In zebrafish, researchers discovered that astrocytes respond to norepinephrine by releasing ATP, which is then broken down into adenosine—an important neuromodulator that signals neurons to stop swimming when progress is futile.

Astrocytes Take Center Stage in Brain Function and Behavior

Long thought to be mere support cells, astrocytes are now shown to play a powerful, dynamic role in regulating brain function and behavior. New research in fruit flies and rodents reveals that astrocytes don’t just support neurons—they selectively respond to neurotransmitters and influence which neural signals are prioritized.

AI’s Spontaneously Develop Social Norms Like Humans

Large language model (LLM) AI agents, when interacting in groups, can form shared social conventions without centralized coordination. Researchers adapted a classic “naming game” framework to test whether populations of AI agents could develop consensus through repeated, limited interactions.
