Restricting daily eating to an 8 to 9 hour window yields cognitive improvements in spatial planning and problem-solving for older, overweight women beyond the benefits of caloric reduction alone.

Human-specific duplicates of the SRGAP2 gene slow microglial maturation to four to eight years.

When accounting for test volatility and regression to the mean, overconfidence is universal, with high performers exhibiting the greatest overconfidence.

While the ACC-to-RSC pathway determines if a behavior becomes a habit, the lOFC-to-central striatum circuit regulates execution intensity, explaining individual habit differences.

A new study reveals that eye state flips the relationship between alpha brain activity and mind wandering.

A new study reveals that the vagus nerve transmits gut nutrient signals to the hippocampus, boosting acetylcholine release and spatial memory.

Researchers investigate cultural differences in subjective cognitive decline.

A new study argues that US suicide statistics significantly undercount deaths by misclassifying up to 30 percent of drug overdoses as accidents.

Engineers develop self-powered wearable sweat patch for continuous levodopa tracking in Parkinson's.

A new study reveals that memory consolidation during sleep requires coordinated signaling among the orbitofrontal cortex, thalamus, and hippocampus, and shows how epileptic spikes break this circuit.

A new study demonstrates that SuperAgers cannot be distinguished from cognitively average peers by APOE status or polygenic risk scores.

Increasing mechanical strain causes particle interactions to erase prior directional memory, providing a physical model for how short- and long-term biological memories compete and overwrite.

A new study demonstrates the feasibility of recall-by-genotype research using the diverse BioMe biobank.

A new study reveals that detailed personalized feedback from humanoid robots causes immediate cognitive overload after errors, slowing immediate recovery despite improving long-term task performance.

A new study reveals that greater Japanese horseshoe bats asymmetrically adjust their echolocation call frequencies to align with colony mates.

A new study links six or more hours of daily social media use to a two-fold increase in anxiety and a three-fold increase in suicidal ideation among youth.

By measuring allele frequency changes across adult age groups, the team identified 168 variants under active selection, including 71 pathogenic mutations under purifying selection.

A long-term hyena study reveals female reproductive inequality exceeds male inequality over multiple generations.

A new study shows that lipoic acid trisulfide (LASSS) protects hepatocyte growth factor (HGF) from age-related nitration.

Using site-specific knockout mouse models, researchers found that GIPR agonists suppress appetite via the brainstem, while GIPR antagonists act in the hypothalamus to release a "brake" on hindbrain satiety.

A new study uses the HiToP framework to map motor symptoms to mental health dimensions in nearly 3,500 individuals.
