Summary: Researchers have developed the first sort-in-memory hardware system capable of tackling complex, nonlinear sorting tasks without traditional comparators. Using a novel Digit Read mechanism and Tree Node Skipping algorithm, the team demonstrated a fast, energy-efficient, and scalable architecture built on memristors.Benchmark tests showed dramatic gains in speed, energy, and...

Summary: 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.Benefits were strongest in urban...

Summary: 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.One model, Gemini, performed worst yet believed it...

Summary: 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.Tau-containing synapses were more likely to be lost, and reactive astrocytes were observed...

Summary: 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...

Summary: 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.These distinct neural pathways explain how psychopathy manifests as both emotional detachment and impulsivity. The findings...

Summary: 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.This challenges stigma and...

Summary: 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.Girls were also more frequently maltreated, though this was not linked to...

Summary: 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.The findings also provide a roadmap to study...

Summary: 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.Rather than reinterpreting negatives as positives, optimists...
