Your Brain Maps the Same Path Differently Every Time

New research shows that our brain’s internal map rewrites itself every time we navigate a familiar environment. Even when mice experienced identical virtual mazes with controlled sensory input, their hippocampal neurons activated in different patterns on each run.

How the Brain Decides to Flee or Freeze

A new study reveals how evolution fine-tunes instinctive fear responses by tweaking a key neural switch deep in the brain. Comparing two deer-mouse species, researchers found that forest-dwelling mice have hypersensitive escape circuits, while open-field mice are more likely to freeze.

Inflammation Influences Cannabis’s Effects on Anxiety and Sleep

A new study shows that inflammation levels influence how cannabis affects anxiety and sleep quality. Researchers found no overall change in inflammatory markers after 4 weeks of cannabis use, but baseline inflammation moderated outcomes.

Math Reveals Why Sleep Patterns Shift With Age, Light, and Routine

A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier. Researchers expanded the classic two-process sleep model by adding the effects of light exposure, uncovering how internal and external factors interact to regulate sleep.

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.
