Strata: Stories from Deep Time’ explores the origins of the air we breathe and untangles some of our planet’s oldest stories.

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

Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable ...

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 ...

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 ...

Cryoelectron microscopy is a method for imaging frozen-hydrated specimens at cryogenic temperatures by electron microscopy. Specimens remain in their native state without the need for dyes or ...

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 ...
