Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

The structure of a spontaneously activated immune protein is determined by cryo-electron microscopy. This reveals the passage of an entire domain through a transient opening. The authors ...

The entorhinal cortex (EC) plays a pivotal role in memory function and spatial navigation, connecting the hippocampus with the neocortex. The EC integrates a wide range of cortical and subcortical ...
