Blood Tests Could Predict Spinal Cord Injury Severity and Survival

A new study shows that routine hospital blood tests could help predict spinal cord injury severity and survival chances. Researchers used machine learning to analyze data from thousands of patients and found that patterns in blood markers, such as electrolytes and immune cells, forecasted recovery outcomes as early as one to three days after admission.

Human Stem Cell Transplants Boost Vision in Advanced Dry AMD

A new clinical trial suggests stem cell therapy may restore vision in people with advanced dry age-related macular degeneration, a disease that currently has no cure. Researchers transplanted retinal pigment epithelial stem cells, derived from adult postmortem eye tissue, into patients’ eyes.

Brain Waves During Sleep Are Driven by Neural Excitability

New research shows that slow oscillations in the brain, which occur during deep sleep and anesthesia, are guided by neuronal excitability rather than structural anatomy. Using computational models and experiments in mice, scientists demonstrated that the most excitable brain region directs the flow of these waves, like a leader setting a trend.

Cleaner Air May Protect Children’s Eyesight and Slow Myopia

New research reveals that cleaner air may protect children’s eyesight and help slow the rise of myopia, especially in younger children. Using machine learning, scientists found that children living in less polluted areas had better vision, even after accounting for genetics and screen time.

Neurology News Articles

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

Oral Bacteria May Trigger Parkinson’s Disease

Scientists have uncovered a direct link between oral bacteria and Parkinson’s disease. They found that Streptococcus mutans, best known for causing cavities, can settle in the gut and release metabolites that reach the brain.

Dementia Prevention Must Begin in Childhood, Not Just Midlife

A large international study shows that the accumulation of social hardships across life—known as the social exposome—has lasting effects on the brain. Adverse exposures, including low education, food insecurity, and limited healthcare, were linked to cognitive decline, mental health issues, and altered brain structure and function.

Unlocking Brain Cell Crosstalk Reveals New Path in Alzheimer’s

A new study reveals that Alzheimer’s disease involves more than just plaques and tangles; it also stems from disrupted communication between brain cells. Using advanced imaging and computational modeling, scientists mapped how neurons and glial cells interact at the molecular level.

Alzheimer’s Research Shifts Toward Immune System Balance

Alzheimer’s disease affects over 55 million people worldwide and has long been linked to toxic protein buildup and chronic inflammation in the brain. A new review shows that adaptive immune cells—T and B cells—also play a crucial role, sometimes worsening brain damage, sometimes offering protection.

When Brain Cancer Cells Stick Together, They’re Less Dangerous

A groundbreaking study has revealed that glioblastoma cells behave differently depending on whether they cluster or disperse. Cells that remain in clusters are less aggressive, while dispersed cells are more plastic, meaning they can adapt and resist treatments more easily.

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.

When Machines Become Our Moral Loophole

A large study across 13 experiments with over 8,000 participants shows that people are far more likely to act dishonestly when they can delegate tasks to AI rather than do them themselves. Dishonesty rose most when participants only had to set broad goals, rather than explicit instructions, allowing them to distance themselves from the unethical act.

Your Words May Reveal More Than You Think: AI Shows How

Psychologists are turning to artificial intelligence to uncover hidden psychological cues in speech, from word choice to tone and pacing.

Psychology News Articles

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

Most Daily Actions Run on Habit, Not Conscious Choice

New research shows that nearly two-thirds of daily behaviors are triggered by habit rather than conscious decision-making. Participants often acted automatically in familiar settings, reflecting learned associations.

Mini Brains Expose Neural Signatures of Schizophrenia and Bipolar

For the first time, lab-grown mini brains have revealed how neurons misfire in schizophrenia and bipolar disorder. Using machine learning to analyze electrical activity, researchers identified distinct firing patterns that served as biomarkers, distinguishing patient-derived organoids from healthy ones with over 90% accuracy.

Parenting Styles Shape Teen Anxiety

A new study shows that both mothers and fathers significantly shape their adolescent children’s social anxiety, but in different ways. Warmth, affection, and acceptance from either parent reduce anxiety, while rejection, coldness, and controlling behaviors heighten it.

Fetal Movements Boost Maternal Attachment

A new study shows that fetal movement frequency in late pregnancy is directly tied to stronger maternal-fetal attachment. Using an actocardiograph, researchers objectively measured movements and found that higher activity was associated with greater emotional bonding, even when controlling for other factors like maternal mood or gestational age.
