Analysis of Rosalind Franklin’s notes challenges claims she missed photograph 51’s significance

Science reports that a new analysis of Rosalind Franklin’s notes challenges the longstanding suggestion that she missed the significance of photograph 51. The notes concern another x-ray image Franklin made just days earlier using the same DNA sample. James Watson’s 1968 memoir implied that the insight prompted by photograph 51 was his alone; Franklin died in 1958 and could not challenge his account.
