Photos and letters show how James Watson and Francis Crick raced to uncover the double helix structure of DNA.

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

A research team has solved the three-dimensional structure of a key protein that helps damaged cellular DNA repair itself. Investigators say that knowing the chemical structure of the protein will ...

A new method for manipulating macromolecules has been developed by researchers. The technique uses double-stranded DNA to direct the behavior of other molecules. A new method for manipulating ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

This monumental scientific achievement occurred within a context of intense international collaboration, rapid technical ...

They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret of life." But James Watson and Francis ...

James Watson, who co-discovered the structure of DNA has died at age 97. He was a scientific superstar until he made racist remarks that made him an outcast.

His collaboration with biophysicist Francis Crick on the molecular key to all living organisms would make him one of the most ...
