A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher ...

Structural insights into transcriptional regulation by the helicase RECQL5 Florez Ariza and Lue et al. use cryo-electron microscopy to investigate how the RECQL5 helicase regulates transcription.

Here we use cryogenic electron microscopy to determine the structure of TbAQP2 from Trypanosoma brucei, bound to either the substrate glycerol or to the sleeping sickness drugs, pentamidine or ...

A Toyota Mirai hydrogen fuel-cell vehicle. (Patrick T. Fallon/Bloomberg News) On Monday night in Atlanta, Donald Trump described a made-up scenario in which GOP Rep. Marjorie Taylor Greene of ...

High-resolution electron microscopy (HREM) imaging technique is a powerful tool for directly visualizing a broad range of materials in real-space. However, it faces challenges in denoising due to ...

A development of high-resolution X-ray microscope with a new type of field emission electron source is now in progress. The X-ray microscope is equipped with a lithium liquid metal electron source (Li ...

We developed a method to improve specimen preparation for electron cryo-microscopy of membrane proteins. The method features a perforated hydrogel nanomembrane that stabilizes the thin film of aqueous ...
