On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA.

Human DNA constantly refolds in 3D space, and these looping dynamics regulate gene expression and cell identity.

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Learn how sex-biased interbreeding between Neanderthals and modern humans explains why Neanderthal DNA is largely missing ...

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

What is that how can a tooth survive the years and bear any intelligible mark of the molecules on its side when bone and other soft tissue have long since decayed? In the case of ancient-DNA, teeth ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...
