Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick.Created by Rosalind Franklin using a technique called X-ray ...

The determination in 1953 of the structure of deoxyribonucleic acid (DNA), with its two entwined helices and paired organic bases, was a tour de force in X-ray crystallography. But more ...

Researchers have identified a form of molecular motion that has not previously been observed. When what are known as "guest molecules"—molecules that are accommodated within a host molecule—penetrate ...
