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).

Cellular recycling process may prevent cancer initiation, finds study

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA.

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.
