Aging Clock Unveils Compounds That Rejuvenate Brain Cells

Scientists developed a computational “aging clock” that measures the biological age of brain cells and identifies compounds with rejuvenating potential. By analyzing gene activity from healthy and neurodegenerative brain tissue, they pinpointed 453 interventions predicted to reverse cellular aging.

AIPasta Creates Illusions of Consensus to Fuel False Beliefs

A new study warns of “AIPasta,” a strategy that uses generative AI to craft many slightly different versions of false claims to mimic widespread public belief. Unlike traditional CopyPasta, which repeats the same message verbatim, AIPasta increased perceptions of consensus, especially among politically predisposed groups.

Tickling Strengthens Bonding Through Oxytocin Pathways

A new study reveals how pleasant touch fosters social bonds between humans and rats by activating oxytocin signaling in the brain. Researchers found that repeated tickling of rats increased their vocalizations, preference for human interaction, and oxytocin receptor expression in the VMHvl region.

COVID Stress May Have Aged Brains Faster

Living through the Covid-19 pandemic may have accelerated brain ageing, even in people who were never infected, a new study finds. Brain scans of nearly 1,000 adults showed older, male, and disadvantaged individuals were most affected.

How Your Body Clock Stays on Time Despite Temperature Changes

Researchers uncovered how our biological clocks keep a 24-hour rhythm even as temperatures fluctuate. Using physics-based models, they discovered that at higher temperatures, gene activity rhythms become distorted—rising faster and falling slower—to maintain the cycle’s duration.

Memristor-Based Hardware Achieves Breakthrough in Nonlinear Sorting

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.

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.
