X-ray radiation from a synchrotron source can rapidly damage, in a very specific way, the structure of a protein, as seen by X-ray crystallography. The four images represent a series of electron density maps collected from the same protein crystal. Protein degradation is indicated by the disappearance of the disulfide bond (yellow bar, surrounded by empty blue cage) linking the carbon chains (white balls). These images represent the first-ever recording of experimentally-induced chemical bond breakage usin
