Green Space Lowers Developmental Risks

Children exposed to more green space before birth and during early childhood have a lower risk of neurodevelopmental disorders, a new study shows. Analysis of over 1.8 million mother–child pairs revealed reduced rates of ADHD, autism, and learning delays in areas with higher vegetation levels.

AI Chatbots Overestimate Themselves, and Don’t Realize It

AI chatbots often overestimate their own abilities and fail to adjust even after performing poorly, a new study finds. Researchers compared human and AI confidence in trivia, predictions, and image recognition tasks, showing humans can recalibrate while AI often grows more overconfident.

Synaptic Tau and Astrocytes Drive PSP Progression

ew research uncovers how tau pathology spreads and damages synapses in progressive supranuclear palsy (PSP). Using human postmortem tissue and live brain slice models, scientists showed tau accumulates in both pre- and postsynaptic terminals, likely propagating neuron-to-neuron.

Hunger Sharpens Sleep Rhythms That Solidify Memories

New research shows that the brain’s slow oscillations and sleep spindles — key rhythms that consolidate memories during sleep — can be shaped by more than just age. While these rhythms have long been thought of as stable traits, studies reveal that metabolic state, like fasting before sleep, can enhance their timing and co-occurrence.

Why the Psychopathic Brain Struggles With Emotion and Control

New research reveals how structural brain connectivity shapes psychopathic traits and externalizing behaviors. Using advanced connectome modeling, scientists identified two key networks: one tied to impaired emotional processing, the other to poor attentional control.

Most Mental Illnesses Arise Without Family History

A massive Danish study shows that most mental illnesses—like schizophrenia, bipolar disorder, and depression—occur in people with no close family history of the condition. Analyzing data from over 3 million individuals, researchers found that while heredity increases risk, most diagnosed individuals do not have affected relatives.

ADHD-Linked Genes Raise Risk of Childhood Maltreatment

Children with higher genetic risk for ADHD are more likely to experience childhood maltreatment, a new study shows. Researchers found that ADHD-associated genetic variants, especially when combined with parental psychiatric diagnoses, increase the likelihood of abuse and neglect.

Hidden Genes in DNA “Dark Matter” Linked to Human Brain Traits

Researchers have identified two genes from the human genome’s “dark matter” that influence brain size and synaptic signaling. Using the complete human genome and zebrafish models, the team showed how these duplicated genes may contribute to what makes the human brain distinctive.

Optimists’ Brains “Think Alike” When Imagining the Future

Optimists’ brains show strikingly similar patterns when imagining the future, while pessimists’ brains display more individual variability, a new study reveals. Using fMRI, researchers found that optimists process positive and negative scenarios in distinct, shared ways, which may explain their greater social connectedness.

Right-Sided Brain Pathway Linked to Social Dominance

A new study uncovers how brain anatomy relates to social dominance in primates. Researchers found that the uncinate fasciculus, a tract tied to emotion and memory, strongly correlated with dominance behaviors in squirrel monkeys. This link was especially pronounced in the right hemisphere, aligning with human findings on social aggression.

Autism Masking Leaves a Mark on the Brain

Some autistic teens mask their traits to “pass” as non-autistic in social settings, but a new study reveals the hidden cognitive toll. Using EEG, researchers found these teens show faster automatic responses to faces and dampened emotional reactivity, suggesting their brains may adapt to cope with social demands.

Pregnancy Stress Disrupts Baby’s Microbiome, Increasing Depression Risk

Prenatal stress in mothers can leave a lasting imprint on their offspring, predisposing them to depression-like behaviors. Researchers found that maternal stress disrupts the gut microbiome and metabolite production, which are vertically transmitted to the young.
