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.

Could a Common Virus Help Drive Parkinson’s?

New research suggests a previously harmless virus may be linked to Parkinson’s disease. Scientists detected Human Pegivirus (HPgV) in the brains and spinal fluid of Parkinson’s patients but not in controls, challenging assumptions that the virus is benign.

Baby Toolbox Transforms Early Infant Development Assessment

The NIH Baby Toolbox is a groundbreaking assessment system designed to evaluate infants’ and toddlers’ development from just 16 days old to 42 months. Using gaze-based learning and tablet-based tools, it allows clinicians and researchers to measure cognitive, motor, language, and social-emotional skills with unprecedented precision.

Why Some 80-Year-Olds Have the Memory of 50-Year-Olds

For 25 years, scientists have studied “SuperAgers”—people aged 80 and above whose memory rivals those decades younger. Research reveals that their brains either resist Alzheimer’s-related plaques and tangles or remain resilient despite having them.

Your Brain Maps the Same Path Differently Every Time

New research shows that our brain’s internal map rewrites itself every time we navigate a familiar environment. Even when mice experienced identical virtual mazes with controlled sensory input, their hippocampal neurons activated in different patterns on each run.

Study Challenges Link Between Football and Brain Protein Buildup

A new study questions whether playing youth football leads to harmful protein buildup in the brain. Researchers examined 174 donated brains, including former high school and college players, and found no link between contact sports and excess tau protein in a key memory region.

Body’s Own Cannabinoids May Help Control Trauma-Linked Fear

A new study reveals that a natural cannabinoid in the body, 2-AG, plays a crucial role in regulating fear responses, particularly in individuals with PTSD and anxiety. Researchers found that lower levels of 2-AG in both mice and humans were linked to exaggerated or overgeneralized fear reactions to non-threatening stimuli. This suggests that 2-AG helps the brain distinguish real threats from harmless cues, acting as a natural filter for fear.

Lingering Bacterial Debris May Drive Post-Treatment Lyme Symptoms

New research suggests that lingering cell wall fragments from the Lyme disease bacterium, Borrelia burgdorferi, may be responsible for persistent symptoms long after antibiotic treatment. These fragments, made of a unique form of peptidoglycan, appear to accumulate in the liver and joints, triggering inflammation and immune responses even after the infection is gone.

Babies Learn Words Without Visuals

Infants as young as 15 months can use language context to infer the meaning of words referring to objects they’ve never seen. Researchers found that when 15-month-olds heard a new word in a familiar context—like "kumquat" during a conversation about fruit—they later identified the unseen object correctly.

Your Brain Learns From Fear, Thanks to Dopamine

New research reveals how dopamine helps the brain learn to avoid unpleasant outcomes by responding differently in distinct brain regions during negative experiences. In a study with mice, scientists tracked dopamine activity over time as animals learned to escape an adverse event, showing that one brain area adapted early in learning while another supported long-term avoidance behavior.

New Genes Linked to Parkinson’s Risk Revealed

Researchers have long wondered why some people with high-risk Parkinson’s gene variants develop the disease while others don’t. A new study has uncovered that additional genetic players, particularly the Commander gene complex, influence whether the disease manifests.

Study Reveals Brain Circuits That Drive Political Passion and Intensity

A new study has identified specific brain networks that regulate the intensity of political engagement, regardless of ideology. By analyzing Vietnam War veterans with localized brain injuries, researchers found that damage to the prefrontal cortex increased political fervor, while damage to the amygdala reduced it.
