Bacteria deep in the soil need "nanowires" made up of cytochrome OmcZ to export electrons to extracellular acceptors in order to survive without oxygen. Our cryo-EM OmcZ architecture explains how bacteria make nanowires on demand and why only OmcZ nanowires show extremely high electron conductivity.

Here, we present Machine learning Assisted, Interferometric Structured Illumination Microscopy, MAI-SIM, as an easy-to-implement method for fast live cell super-resolution imaging in multiple colours.

Triboelectrification excited by breathing continuously replenishes electrostatic charges, endowing the self-charging face mask with an ultralong service lifespan
