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).

Consistent Evidence Links Ultra-Processed Food To Over 30 Damaging Health Outcomes

Consistent evidence shows that higher exposure to ultra-processed foods is associated with an increased risk of 32 damaging health outcomes including cancer, major heart and lung conditions, mental health disorders, and early death.

New tool unravels the mystery of DNA-RNA interactions in single cells

Cancers begin with abnormal changes in individual cells, and the ability to track the accumulation of mutations at the single-cell level can shed new light on the early stages of the disease. Such knowledge could enable more effective early detection and treatment options for patients as well as more accurate predictions of disease progression.
