3-D reconstruction articles from across Nature Portfolio

FluoEM aligns axon reconstructions from fluorescence and 3D electron microscopy on the same tissue to allow multicolor labeling of distant inputs.

R-type pyocins, produced by Pseudomonas aeruginosa, are sheath-tube nanomachines that puncture the envelopes of target cells, inducing their death. Cryo-EM studies reveal the atomic structures of the pyocin R2 in its extended precontraction and postcontraction forms, which suggest a mechanism for the contraction process of this molecular syringe.
