Vitamin D May Slow Biological Aging

New results from the VITAL randomized trial show that daily vitamin D3 supplementation helps preserve telomere length in older adults, potentially slowing a key biological aging process. Telomeres are protective caps on chromosomes that shorten with age and are associated with chronic diseases.

Gabapentin Linked to Longer Survival in Glioblastoma Brain Cancer

A new study suggests that gabapentin, a widely used anti-seizure medication, may improve survival in patients with glioblastoma (GBM), the deadliest form of brain cancer. Researchers found that GBM patients taking gabapentin lived several months longer than those who did not, across two independent hospital datasets.

AI Tool Reads Faces to Predict Health, Aging, and Cancer Outcomes

Researchers have developed an AI tool called FaceAge that uses facial photos to estimate biological age and predict survival outcomes in cancer patients. In a study involving over 6,000 patients, those with cancer had FaceAges about five years older than their chronological age, and higher FaceAges were linked to poorer survival.

Heart’s Rhythm May Help Forecast Cognitive Longevity

Healthy hearts show complex, adaptive rhythms that reflect resilience to internal and external changes. Researchers applied a novel method to analyze heart rate complexity using wearable pulse oximeters and found that greater complexity predicted slower cognitive decline in older adults.

AI Predicts Brain Cancer Recurrence in Kids

Researchers have developed an AI model that analyzes sequences of brain scans to accurately predict tumor recurrence in children with gliomas. By applying a method called temporal learning, the model interprets subtle changes in MR images taken post-treatment over time. The study found that using multiple images significantly outperforms traditional single-scan analysis, reaching prediction accuracy rates as high as 89%.

Shared Brain Circuit Drives Political Passion Across Ideologies

A new study has identified a brain circuit that correlates with how intensely people engage in politics, regardless of their political beliefs. Researchers examined data from 124 male military Veterans with penetrating brain injuries and found that lesions in certain brain areas affected levels of political involvement.

Blocking Tim-3 Boosts Microglia in Alzheimer’s

New research reveals that the immune checkpoint molecule Tim-3 plays a critical role in how microglia, the brain’s immune cells, respond to Alzheimer’s disease. While Tim-3 normally helps maintain brain homeostasis, it can also inhibit microglia from clearing harmful plaques that accumulate in Alzheimer’s.

Childhood Adversity Weakens Brain Connectivity, But Support Protects It

New research shows that difficult early-life experiences are linked to weaker white matter connections across the adolescent brain, which may lead to lower cognitive performance. These “communication highways” in the brain are essential for functions like language and mental arithmetic and are shaped by early environmental influences.

Alzheimer’s Study Identifies 16 Risk Genes

A large whole-genome sequencing study has uncovered 16 new genes linked to Alzheimer’s disease, expanding genetic research beyond European ancestry. Researchers analyzed data from 49,149 individuals, nearly half of whom were from underrepresented populations, to improve understanding of genetic risk factors.

“Weekend Warrior” Workouts Cut Risk of Over 200 Diseases

A new study has revealed that "weekend warrior" exercise patterns—concentrating physical activity into one or two days a week—can reduce the risk of over 200 diseases, including heart disease and diabetes. The research found that weekend warriors benefit just as much as those who exercise more evenly throughout the week, provided they meet the recommended 150 minutes of moderate-to-vigorous exercise per week. The study analyzed data from nearly 90,000 individuals, highlighting the broad health benefits of staying active, regardless of how exercise is distributed.

One-Third of Former NFL Players Fear They Have CTE

A new study of nearly 2,000 former NFL players reveals that about one-third believe they have chronic traumatic encephalopathy (CTE), a condition linked to repeated head trauma. Those who believed they had CTE reported higher rates of cognitive problems, depression, chronic pain, and suicidality compared to those who did not.

Ozempic Linked to Increased Risk of Blinding Eye Condition

A new study reveals that patients prescribed semaglutide (Ozempic or Wegovy) for diabetes or weight loss have a higher risk of developing NAION, a potentially blinding eye condition. Diabetic patients on semaglutide were over four times more likely to be diagnosed with NAION, while overweight patients were over seven times more likely. The findings suggest the need for careful discussions between patients and doctors about this risk. NAION remains a rare but serious condition with no effective treatments.
