Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Study links androgens to aggressive childhood brain tumor growth

An international team led by researchers at Baylor College of Medicine, Texas Children's Hospital, McGill University and University of Pittsburgh School of Medicine has discovered what drives the growth of a lethal pediatric brain tumor called Posterior Fossa Type A (PFA) ependymoma.

Stroke may trigger younger brain patterns in unaffected regions

In a new study published in The Lancet Digital Health, scientists at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) have discovered that the brains of people who experience severe physical impairment after a stroke may reorganize themselves in unexpected ways, showing signs of "younger" brain structure in undamaged regions as they adapt to injury.

New approach helps immune cells find and attack solid tumors

A technique that transforms immune cells into cancer-seeking bloodhounds may overcome a roadblock that has hampered immunotherapy for solid tumors, according to a new study by Stanford Medicine researchers.

Scientists discover similarities in brain aging between mice and humans

By scanning the brains of mice throughout their lifespans, scientists at Columbia's Zuckerman Institute and the University of Texas at Dallas have discovered that the human brain is not unique in how it changes with age.

New protein atlas identifies distinct subtypes of neurodegenerative diseases

Neurodegenerative diseases form a tangled biological web with overlapping molecular signatures and symptoms. To decode this complexity, a multi-institute collaboration led by St. Jude Children's Research Hospital scientists developed the pan-neurodegeneration atlas (PanNDA).

Early adulthood hypertension linked to heart and kidney disease later in life

Higher blood pressure during young adulthood is likely linked to a higher risk of heart disease and kidney disease later in life, reinforcing the importance of maintaining healthy blood pressure at younger ages, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Replacing sedentary time improves insulin resistance in adolescents

Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Study finds addiction risk tied to reward and impulse genes

Most of the genetic risk for developing a substance use disorder comes from genes that broadly affect how our brains process rewards, regulate impulses and weigh consequences – not from genes that specifically influence substance use disorder or any single drug.

Balancing sitting and movement may lower the risk for hypertensive disorders of pregnancy

During pregnancy, women can reduce their risk of developing a hypertensive disorder by nearly 30% by limiting sedentary time to no more than eight hours a day and increasing light, everyday physical activity to at least seven hours a day, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.
