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.

How Do Genetic Mutations Cause Disease?

Mutations in genes can lead to genetic disorders, impacting health. Understand the types, causes, and implications of genetic mutations and disease.

Newly discovered protein helps preserve egg chromosome integrity during aging

Eggs follow a very different developmental path from sperm. Once a male hits puberty, sperm cells are produced continuously throughout his life.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Study redefines picobirnavirus as a bacteria hunting virus

Thriving alongside trillions of bacteria in the human digestive tract is a vast population of viruses. Ever since one such denizen of the gut microbiome, known as picobirnavirus, was first spotted decades ago, researchers thought it directly infected human tissue and played a role in gastrointestinal illness.

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.

A village beyond Sardinia's blue zone shows striking survival among older women

Researchers studying Bolotana, Sardinia, found that women had exceptionally high estimated late-life survival during 2021–2025, with their probability of surviving from age 70 to 100 exceeding regional and national averages by more than threefold. Earlier demographic estimates showed a much smaller survival advantage, prompting the authors to classify Bolotana as a candidate longevity blue zone that requires further investigation.

Newly discovered protein controls the space between mitochondrial membranes

Mitochondria are the tiny powerpacks that supply most of the energy our cells need. Their ability to generate this energy relies on a distinctive architecture: two membranes, one tucked inside the other, separated by a narrow gap called the intermembrane space (IMS).
