Gene Editing Reverses Age-Related Memory Loss

Researchers have identified molecular mechanisms behind age-related memory decline — and shown they can be reversed. Two studies revealed that correcting specific molecular processes in the hippocampus and amygdala, and reactivating a silenced memory-supporting gene called IGF2, improved memory in older rats.

Pain Resilience, Not Pain Itself, Predicts How Active People Stay

A new study reveals that how people think about and cope with chronic pain is more important than the pain itself in determining physical activity levels. Researchers found that individuals with higher pain resilience — the ability to maintain positive functioning despite pain — were significantly more active than those with lower resilience.

Lack of Sleep in Teens Linked to Higher Suicide Risk

Teenagers who sleep less or experience frequent night awakenings are significantly more likely to attempt suicide later in adolescence, according to a major longitudinal study. Researchers analyzed data from more than 8,500 teens and found that poor sleep at age 14 predicted suicide attempts by age 17, even after accounting for other mental health risk factors.

Brain’s Waste System Breakdown Linked to Dementia Risk

Researchers have discovered that problems with the brain’s waste-clearing system—the glymphatic system—may significantly raise the risk of developing dementia. In one of the largest studies to date, MRI data from 40,000 adults revealed that impaired cerebrospinal fluid (CSF) flow predicts dementia risk years before symptoms appear.

Poor Oral Health Linked to Brain Damage Markers

A new study finds that older adults with gum disease are more likely to show signs of white matter damage in the brain — a change tied to memory decline, balance issues, and higher stroke risk. MRI scans revealed that participants with gum disease had significantly more white matter hyperintensities than those without, even after accounting for age and other health factors.

Neurology News Articles

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

Oral Bacteria May Drive Multiple Sclerosis

Scientists have found that people with multiple sclerosis (MS) have a distinctly imbalanced oral microbiome—marked by a loss of beneficial bacteria and a rise in inflammation-linked microbes. Using advanced genetic and metabolic profiling, researchers revealed that saliva from MS patients also had lower levels of hypotaurine, a molecule that supports antioxidant defense and nerve health.

New AI Tool Reveals Genetic Link Between Memory Cells and Alzheimer’s

A new computational tool developed by researchers has uncovered genetic evidence directly linking Alzheimer’s disease to the loss of memory-making neurons, helping to resolve a decades-long mystery in dementia research. The algorithm, called seismic, matches genetic data to individual cell types, outperforming previous methods and highlighting how specific brain cells—not just immune cells—are implicated in Alzheimer’s.

Long-Term Keto Diet May Damage Your Body

A new study reveals that while the ketogenic diet can prevent weight gain, it may cause severe long-term metabolic problems. Researchers found that mice on a long-term keto diet developed fatty liver disease and impaired blood sugar regulation due to stressed pancreatic cells.

First Signs of Multiple Sclerosis Found Years Before Symptoms

Researchers have traced the earliest stages of multiple sclerosis (MS), showing that the immune system begins attacking the brain up to seven years before diagnosis. By analyzing over 5,000 blood proteins, they identified molecular signs of damage to myelin—the protective sheath around nerve fibers—long before symptoms emerge.

Can a Disconnected Brain Be Conscious?

A new study reveals that sleep-like slow-wave brain activity can persist for years in surgically disconnected brain hemispheres of awake epilepsy patients. Using EEG recordings, researchers found that the isolated cortex exhibits patterns similar to deep sleep, anesthesia, or vegetative states—suggesting absent or reduced awareness.

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.

Why AI Conversations Still Sound Fake

A new study comparing human and AI-generated conversations reveals that large language models like ChatGPT and Claude still fail to convincingly mimic natural human dialogue. Researchers found that these systems over-imitate their conversation partners, misuse filler words such as “well” or “like,” and struggle with natural openings and closings.

People Miss Racial Bias Hidden Inside AI Emotion Recognition

A new study reveals that most people fail to recognize racial bias embedded in AI systems, even when it is visible in the training data. The research shows that artificial intelligence trained on imbalanced datasets—such as happy white faces and sad Black faces—learns to associate race with emotion, perpetuating biased performance.

AI Builds the Most Detailed Map of the Mouse Brain Yet

Researchers have created one of the most detailed maps of the mouse brain ever made, using artificial intelligence to reveal 1,300 distinct regions and subregions. The AI model, called CellTransformer, identified new brain areas that had never been charted before, providing an unprecedented view of brain organization.

AI Images That Change When Rotated Reveal How the Mind Sees

Researchers have developed AI-generated “visual anagrams” — images that transform into entirely new objects when rotated — to explore how the brain processes perception. Unlike traditional optical illusions, these rotating images allow scientists to isolate how people interpret size, emotion, and animacy in visual information.

AI Learns to Design the Human Body’s Most Elusive Proteins

A new machine learning method has achieved what even AlphaFold cannot — the design of intrinsically disordered proteins (IDPs), the shape-shifting biomolecules that make up nearly 30% of all human proteins. These unstable proteins play key roles in cellular communication, sensing, and disease, yet their ever-changing structures have defied traditional AI prediction models.

Psychology News Articles

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

Ketamine Fails to Outperform Placebo in Major Depression Trial

A large randomized and blinded clinical trial has found no additional benefit of repeated ketamine infusions over standard inpatient care for treating major depression. The study compared ketamine with a psychoactive placebo and found no meaningful differences in objective or self-reported depression scores, cognition, or quality of life.

Hearing Voices May Stem from the Brain Misreading Its Own Inner Speech

A new study reveals that auditory hallucinations in schizophrenia may arise when the brain fails to recognize its own inner voice as self-generated. Normally, the brain predicts the sound of one’s inner speech and dampens auditory responses accordingly, but this prediction breaks down in people who hear voices.

When a Hug Turns Dark: How Manipulative Partners Use Touch

Touch can strengthen bonds and calm stress, but not all affection is sincere. A new study reveals that people with “dark triad” traits—narcissism, psychopathy, and Machiavellianism—often use physical touch to control or manipulate their romantic partners.

Why Teenage Songs Define Us: The Science of Musical Memory

A global study reveals that our most emotionally resonant music tends to come from our teenage years—typically peaking around age 17. This “reminiscence bump” marks the period when our developing brains most strongly imprint musical memories that help form identity.

Child Abuse Leaves Lasting Biological Scars on the Brain and DNA

New research reveals that child maltreatment leaves measurable biological “scars” on DNA, altering brain structure and function. Using a genome-wide epigenetic analysis, scientists identified four key methylation sites—ATE1, SERPINB9P1, CHST11, and FOXP1—linked to maltreatment.

Genes Linked to Cannabis Use Reveal Ties to Mental Health

Researchers analyzing data from over 130,000 participants have identified specific genes associated with cannabis use and its frequency, revealing strong links to psychiatric, cognitive, and physical health traits. The genes CADM2 and GRM3, already known for roles in brain communication and impulsivity, appear central to how individuals initiate and sustain cannabis use.

How Storytelling Style Shapes the Way the Brain Forms Memories

The way an event is described—through feelings or sensory detail—changes how the brain stores and recalls it. In this study, participants listened to stories that emphasized either conceptual details (thoughts and emotions) or perceptual details (sights and sounds).

Over 99% of Heart Attacks Linked to At Least One Known Risk Factor

A massive international study shows that nearly all heart attacks, strokes, and cases of heart failure occur in people with at least one known cardiovascular risk factor. More than 9 million South Korean adults and thousands of U.S. adults were tracked, revealing that over 99% had nonoptimal blood pressure, cholesterol, blood sugar, or tobacco use years before their first event.
