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.

Type I CRISPR Systems Regulate Embedded Innate Immunity Genes in Neisseria

The main function of CRISPR-Cas systems, the revolutionary tool scientists now employ to edit genes, is to defend bacteria against threats such as viruses called bacteriophages. Researchers have continued to study all flavors of CRISPR-Cas systems (to date, 2 classes, 7 types and 46 subtypes have been identified) to understand all their capabilities.

Study Uncovers Two Distinct Embryonic Macrophage Populations with Different Repair Abilities

In leukemia's most aggressive forms, the blood cell factories in our bone marrow falter. Instead of dividing and multiplying at their usual prolific pace, generating hundreds of billions of new cells daily, some precursor cells stall out at an immature stage.

Study Reveals How Genome Regulation Changes During Brain Aging

Researchers have discovered that the human brain undergoes widespread age-related changes in genome regulation beginning in midlife that may help explain why aging is the greatest risk factor for neurodegenerative diseases such as Alzheimer's.

Demographic Biases Threaten the Fairness of Global Single-Cell Human Atlases

The single-cell "atlases" that are increasingly used to map the human body and as training data for artificial intelligence models, may not represent the world's populations fairly, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai.

New Research Links DNA Hypomethylation to Faster Growing Brain Tumors

A form of glioma, a type of brain cancer, tends to progress towards greater malignancy due to an increasing tendency of the glioma cells to transform into immature, stem-cell-like states, according to a study led by investigators at Weill Cornell Medicine, the New York Genome Center, Harvard Medical School and Mass General Brigham.
