Rosalind Franklin knew about DNA's double-helix structure ahead of Watson and Crick, a new study of her photos and notes reveals.

"Photo 51" was a cleaner version of an earlier X-ray image, "Photo 49," that Rosalind Franklin had already used to calculate key features of DNA, challenging long-held assumptions about her role in ...

Notes by the scientist pointing to a helical structure once again challenge the distorted account of her role in the ...

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 ...

The work of British chemist Rosalind Franklin (1920–1958) played an integral role in the discovery of the structure of DNA, but it took many years for Franklin’s contributions to be fully recognized.
