DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Scientists discover new genetic mutations causing inherited deaf-blindness

A team of scientists from Sechenov First Moscow State Medical University together with their colleagues from leading scientific centers of Moscow and India described a number of genetic mutations causing Usher syndrome (inherited deaf-blindness).

Synthetic compound from flaxseed can improve heart function in mice with sepsis

Sepsis is a life-threatening systemic inflammatory condition that develops in response to infection. One of its major complications is cardiovascular dysfunction, in which deterioration of the heart muscle, driven by decreased energy production resulting from reduced oxygen and nutrient supplies, frequently ends in organ failure.

Diversity among rural Africans extends to their gut microbiomes

Our microbiome, the complex community of bacteria, fungi, parasites, and other microorganisms in and on our bodies, reflects the way we live. If we own a pet, we likely share microbes with them. If we eat meat, the microbiome in our intestines may look different from that of a vegan.
