Lingering Brain Changes May Raise Depression Relapse Risk

Even after symptoms subside, people who’ve experienced depression may retain a heightened sensitivity to punishment and negative feedback. A new study found that the brain's habenula—key to processing aversive signals—remains hyperactive in those with remitted depression, particularly during the anticipation of unpleasant outcomes.

How the Brain Forms Indirect Associations to Guide Complex Decisions

A new study reveals how the brain can make decisions based not only on direct experiences, but also on indirect associations between seemingly unrelated stimuli. In experiments with mice, researchers showed that a sweet taste could be rejected after it was indirectly linked to an aversive event through a shared scent.

Brain Fatigue: How the Mind Decides When to Push or Quit

A new study reveals how the brain responds to mental exhaustion, identifying two key regions—the right insula and the dorsolateral prefrontal cortex—that become more active as cognitive fatigue builds. Using functional MRI, researchers observed how volunteers responded to demanding memory tasks and how their willingness to continue changed based on internal fatigue and external rewards.

Death Isn’t the End: AI Brings Lost Voices Back to Life

A new paper explores how generative AI is transforming the way we interact with the dead, from virtual reality reunions to lifelike digital avatars. These “generative ghosts” can remember, plan, and even evolve—offering real-time conversations that go far beyond pre-recorded memorials.

How the Brain Filters Distractions to Stay Focused on a Goal

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.

Brain Injury Could Explain Sudden Criminal Behavior

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 damage to this region.

Smarter Minds Predict Better: IQ Linked to Sharper Life Forecasting

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 were less frequent and less extreme compared to their lower-IQ counterparts.

Brain Structure Differences Linked to Antisocial Traits in Psychopathy

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.

Short Naps Linked to “Aha” Moments and Creative Insight

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.

Robotic Heart Transplant Marks Surgical Breakthrough

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.

AI Reveals How Your Words Reflect Personality

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.

Neighborhood Disadvantage Linked to Alzheimer’s Biomarkers and Inflammation

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.
