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).

Study reveals why older male fruit flies are more likely to pass mutations onto their offspring

The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers.

Green tea may protect against telomere shortening due to biological aging

A new study in Scientific Reports aimed to analyze the association between cross-section and longitudinal LTL changes with the consumption of soft drinks, coffee, and tea among middle-aged and older Korean men and women for six years. It also assessed any changes in the association results according to a difference in sex and age groups.

Researchers discover a protein that makes melanoma more aggressive

Research led by Queen Mary University of London, King's College London and the Francis Crick Institute has identified a protein that makes melanoma, the most serious type of skin cancer, more aggressive by giving cancer cells the ability to change the shape of their nucleus – a characteristic which allows the cells to migrate and spread around the body.
