Dark Personality Traits in Politicians Fuel Political Polarization

New research reveals that politicians with narcissistic, psychopathic, or Machiavellian traits significantly increase affective polarization among voters. When citizens identify ideologically with such leaders, they become more hostile toward political opponents.

Brain Learns to Tune Out Distractions with Repeated Exposure

Our brains can adapt to filter out repeated distractions, according to a new EEG study. Participants learned to ignore frequent visual distractions, such as a red shape in the same location, while searching for a target.

Fussiness at 9 Months May Signal Early Autism Risk

Signs of autism may be detectable as early as 9 months of age, well before the typical diagnosis window of 3 to 5 years. Researchers found that infants who were described by parents as fussy, slow to adapt, or delayed in development were more likely to show autism-related traits by 12 months.

Neurology News Articles

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Why Nostalgic Songs Spark the Brain’s Memory and Reward System

Listening to nostalgic music activates key brain regions tied to memory and emotion, according to a new brain imaging study. Researchers found that songs linked to personal memories engage both the default mode network and the brain's reward circuitry.

Digital Tech May Reduce Dementia Risk

Contrary to fears of "digital dementia," new research finds that using digital technology is linked to a reduced risk of cognitive decline in older adults. A large-scale meta-analysis of over 400,000 participants revealed that digital engagement correlates with a 58% lower risk of cognitive impairment.

Shared Protein Link Found Between Parkinson’s and Cancer

A new study reveals that the protein alpha-synuclein, known for its role in Parkinson’s disease, also contributes to the development of melanoma by promoting excessive DNA repair and cell proliferation. While in neurons, excess alpha-synuclein leads to cell death, in melanoma cells it enables uncontrolled growth by recruiting repair proteins to DNA breaks.

AI News Articles

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

How Psychology Has Shaped, and Continues to Shape, AI

Psychology has been instrumental in the evolution of artificial intelligence, offering foundational insights into learning, cognition, and behavior that have shaped key AI technologies. From early neural networks based on Hebbian learning to modern deep learning and metacognition, psychological theories continue to inform AI’s development.

What Are Thoughts? Exploring the Mystery of the Mind

The nature of thought remains one of philosophy's greatest mysteries, with deep implications for neuroscience and artificial intelligence. Two main theories compete: materialism, which sees thoughts as brain states, and dualism, which holds that thoughts are non-physical entities. While neuroscience has mapped correlations between brain activity and mental states, it cannot yet explain how physical matter gives rise to conscious experience.

When AI Becomes a Lover: The Ethics of Human-AI Relationships

As AI technologies grow more human-like, some people are forming deep, long-term emotional bonds with them, even engaging in non-legally binding marriages. A recent opinion paper explores the ethical risks of such relationships, including their potential to undermine human-human connections and provide dangerous or manipulative advice.

Psychology News Articles

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

LSD-Inspired Drug Reverses Psychosis Brain Damage Without Hallucinations

A new LSD-derived compound called JRT shows promise for treating schizophrenia and other brain disorders without inducing hallucinations. Developed by researchers who altered just two atoms in LSD’s structure, JRT maintains the psychedelic’s neuroplastic effects while avoiding its psychosis-linked risks.

Nearly Half of U.S. Adults Report Weekly Stress from News

A new national survey reveals that 45% of U.S. adults experience stress at least once a week due to news or social media, with 16% feeling stressed daily. While stress is a natural response to caring deeply about issues or people, chronic exposure without relief can negatively affect both mental and physical health.

Police at Greater Risk of Brain Trauma and PTSD

A large new study reveals police officers are more than twice as likely to sustain traumatic brain injuries (TBIs) as the general population, with those injured on duty facing double the risk of developing complex PTSD. The research, which surveyed over 600 UK frontline officers, found that 38% had experienced at least one TBI, often accompanied by symptoms like confusion or memory loss.

Smell Test at Home May Sniff Out Early Cognitive Decline

A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.

Low Vitamin K Intake May Accelerate Age-Related Memory Decline

A new study reveals that insufficient vitamin K may harm brain health and memory as we age. In rodent models, a vitamin K-deficient diet led to increased brain inflammation and fewer newly formed neurons in the hippocampus—key factors in learning and memory.

Glutamate Unlocks Brain Cell Channels to Enable Thinking and Learning

Researchers used advanced cryo-electron microscopy to capture atomic-level images of how glutamate, a key neurotransmitter, opens channels in brain cells. These channels, known as AMPA receptors, are essential for neuron-to-neuron communication and play a role in learning, memory, and disorders like epilepsy.

Herpes Virus Linked to Long-Term Brain and Neurological Problems

A new study reveals that herpes simplex virus-1 (HSV-1), commonly known for causing cold sores, can travel through the nasal cavity directly to the brain, causing severe and lasting neurological symptoms. In animal experiments, nasal HSV-1 infection led to persistent neurological dysfunction, including anxiety and cognitive impairment.

The Body Remembers: Trauma Leaves Lasting Biological Imprints

Survivors of the 1995 Oklahoma City bombing continue to carry hidden biological imprints of trauma, even decades after the event and in the absence of visible mental health issues. A new study reveals subtle yet significant changes in stress biomarkers, including cortisol levels, heart rate, blood pressure, and inflammatory interleukins.
