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

Dumpster Diving in Cancer Tissue Uncovers an Immune Evasion Mechanism

A stem cell–derived human embryo model at a developmental stage equivalent to that of a human embryo at day 12 has all the compartments typical of this stage. The top sphere contains the part that will become the embryo itself, capped by the amnion; the bottom sphere is the yolk sac; the interface between them is a critical structural feature of human embryonic development. The two spheres are encapsulated by a cellular layer that will become the placenta
