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.

Tiny Brain Folds Linked to Reasoning Skills in Children

New research reveals that small, shallow grooves in the human brain—called tertiary sulci—are closely tied to reasoning ability and brain connectivity in children and adolescents. These uniquely human folds appear to bring critical brain regions closer together, enhancing communication and cognitive function.

AI-Guided Gene Vectors Precisely Target Brain and Spinal Cells

Scientists have engineered dozens of adeno-associated virus (AAV) systems that ferry genes to specific neuron and glial subtypes in the brain and spinal cord with unprecedented accuracy. Powered by AI-selected DNA “light switches,” the vectors can switch on therapeutic or research genes only in targeted cells—eliminating the need for transgenic animals and enabling fine-grained circuit mapping, activation, or silencing.

Long COVID Is Fueling a Mental Health Crisis in Children

A new study reveals that nearly 40% of children with long COVID are experiencing significant symptoms of anxiety or depression, many for the first time. Using validated mental health screening tools, researchers found that 1 in 4 children had new anxiety symptoms and 1 in 7 had new depressive symptoms, despite no prior mental health history.

How the Brain Stores and Edits Memories

A new scientific review maps the cellular and molecular mechanisms behind memory formation, consolidation, generalization, and updating—revealing how memories are stored, altered, and even manipulated in the brain. Key breakthroughs now allow scientists to visualize and activate specific neurons involved in memory, offering deeper insight into how learning occurs and how fear memories may become overgeneralized in disorders like PTSD.

8-Minute MRI Scan Can Diagnose MS Without Lumbar Puncture

A groundbreaking study has shown that multiple sclerosis (MS) can now be accurately diagnosed with a specialized MRI scan, eliminating the need for invasive and often painful lumbar punctures. The scan, which takes just 8 minutes, detects brain lesions centered on veins—a hallmark of MS—using a technique called T2*-weighted MRI.

Why Loneliness Hurts More When You’re Poor

A new study across 20 European countries shows that people in the lowest income brackets are significantly more likely to feel lonely than those with higher incomes, even though they socialize just as often. Loneliness was closely tied to a cluster of defensive symptoms—pain, fatigue, and low mood—which were especially severe among the poor.

TEAD Proteins Switch Roles in Brain Development

New research shows that TEAD proteins, long known for promoting the growth of neural progenitor cells, also help those same cells mature into neurons and glia—depending on their molecular partners. In early development, TEAD proteins bind with YAP to drive cell proliferation, but later they switch to a different partner, INSM1, which promotes cell differentiation.

Peer Pressure, Perceived Norms Drive Risky Drinking

A new study highlights how peer pressure and misperceptions about campus drinking norms can lead college students to drink more heavily than they intend. Many students believe their peers consume more alcohol than they actually do, which can increase risky behavior and negative outcomes.

This shows foods entwined into a DNA strand.

Plant-Based Diet Could Turn Back Biological Aging

A new study suggests that eating more plant-based foods rich in natural compounds called methyl adaptogens—like turmeric, berries, garlic, and green tea—may slow the body’s biological aging process. Researchers analyzed DNA methylation, a cellular marker of aging, in men aged 50 to 72 who followed a nutrient-rich, plant-forward lifestyle.

New Alzheimer’s Drug Boosts Brain Protection, Restores Memory

Researchers have identified a promising drug candidate, DDL-357, that improves memory in Alzheimer’s mouse models by increasing levels of a protective brain protein called clusterin (CLU). CLU helps prevent the buildup of toxic amyloid-beta plaques and tau proteins, both key drivers of Alzheimer’s disease.

Cold Sore Virus Linked to Alzheimer’s, Antivirals May Lower Risk

A large study suggests that symptomatic infection with herpes simplex virus 1 (HSV-1)—best known for causing cold sores—may significantly raise the risk of developing Alzheimer’s disease. Researchers found that people with HSV-1 were 80% more likely to have Alzheimer’s, while those treated with antiviral medications had a 17% lower risk.
