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 ...

DNA might be too small to see with the unaided eye, but it packs our cells in shocking quantities: More than six and a half feet of DNA lies within every cellular nucleus. It squeezes into such a ...

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 ...

On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA. DNA or deoxyribonucleic acid, is the hereditary material in humans and almost ...

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, ...

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 ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...
