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).

Australian bull ants' venom component exploits a pain pathway in mammals

Australian bull ants have evolved a venom molecule perfectly tuned to target one of their predators – the echidna – that also could have implications for people with long-term pain, University of Queensland researchers say.
