Summary: A new attention model reveals how the human brain allocates limited perceptual resources to focus on goal-relevant information in dynamic environments. Researchers developed “adaptive computation,” a system that prioritizes important visual details—like traffic signals over flashy cars—based on task relevance.In experiments tracking multiple moving objects, the model successfully predicted...
Brain Injury May Help to Explain Sudden Criminal Conduct
Summary: A new study has found that damage to a specific white matter pathway in the brain—the right uncinate fasciculus—may increase the likelihood of criminal or violent behavior following brain injury. Researchers analyzed scans from individuals who began committing crimes after suffering strokes, tumors, or traumatic injuries and found consistent...
Better IQ Prediction and Sharper Life Forecasting are Linked to Smarter Minds.
Summary: New research reveals that individuals with higher IQs are significantly better at predicting future outcomes, leading to smarter decision-making. Using data from the English Longitudinal Study of Ageing, researchers assessed how accurately people over 50 could estimate their own life expectancy.High-IQ individuals were found to make more precise forecasts—errors...
Differences in brain structure are related to aggressive traits in neuroticism
Summary: A new neuroimaging study has identified distinct structural brain differences in individuals with psychopathy, particularly those with high antisocial traits. Reduced volumes were found in subcortical and cortical areas involved in emotion, decision-making, and social behavior.These brain changes were most strongly associated with factor 2 psychopathy traits, such as...
Little Naps Associated with Creative Insight and” Aha” Moments
Summary: A new study suggests that a short nap, especially one reaching deeper N2 sleep, can significantly boost problem-solving insight. Participants who achieved N2 sleep were far more likely to discover a hidden shortcut in a task after napping.EEG data showed that a steeper spectral slope during sleep—indicative of deeper...
A mechanical heart transplant marks a milestone in surgery
Summary: Surgeons have performed the first fully robotic heart transplant in the U.S., using advanced robotic tools to avoid opening the chest. This technique involved precise incisions and accessing the heart through the preperitoneal space, preserving the chest wall.Benefits of the robotic approach include faster recovery, reduced infection risk, and...
Artificial Discovers How Your Words Echo Personality
Summary: Researchers have shown that AI can detect personality traits from written text and, crucially, now understand how these models make decisions. By applying explainable AI techniques like integrated gradients, the team uncovered how specific words and linguistic patterns contribute to predictions based on major psychological frameworks.The study found that...
Neighborhood Negative Impact on Alzheimer’s Biomarkers and Infection
Summary: Living in disadvantaged neighborhoods may increase the risk of Alzheimer’s disease by elevating biomarkers associated with inflammation and neurodegeneration. A long-term study of 334 older adults found higher levels of tau and YKL-40, biomarkers linked to Alzheimer’s and brain inflammation, in people from less advantaged areas.These associations remained even...
Mental Decline Is Slowed by Being Effective.
Summary: Regular physical activity isn’t just good for the body—it protects the brain as we age. A 16-year study of over 13,000 adults found that sustained physical activity significantly slowed cognitive decline.Even modest increases in weekly activity, from light chores to vigorous exercise, were associated with measurable brain benefits. The...
Why Baby Chat Might Be Specially People
Summary: Child-directed speech, or “baby talk,” plays a crucial role in language development and is a near-universal human behavior. Researchers investigated whether this vocal strategy is shared with our closest relatives, the great apes, and found that humans use infant-directed speech far more frequently.Although all great ape infants were exposed...
