DNA dominates life on Earth, but modern chemistry and evolutionary theory suggest it may be only one possible solution for biology. Scientists have already demonstrated alternative genetic systems in ...

To fight viruses, bacteria have evolved a way to make new DNA without copying it.

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

Human environmental DNA is ubiquitous in air, soil and water samples and can be traced to individuals, demonstrating new scientific possibilities but raising ethical concerns around consent with eDNA ...

DNA isn’t just for labs — you can explore it right at home or in the classroom with simple, hands-on experiments. From extracting strawberry DNA with dish soap to modeling the double helix with beads, ...

Researchers have identified four more members of Sir John Franklin's 1845 expedition, one of whom was the subject of great ...

Beef jerky and some woolly mammoths have at least one thing in common: Drying turns their DNA into super-tough glass. This glassy DNA is so stable that it preserved the three-dimensional structure of ...
