Despite their name, giant viruses are difficult to visualize in detail. They are too big for conventional electron microscopy, yet too small for optical microscopy used to study larger specimen. Now, ...

The ability of single particle cryo-electron microscopy to capture structural information on samples that could not be crystallized for use with crystallographic methods or were too delicate for ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...

Bacteriophages, or phages, viruses that selectively target and infect bacteria, have drawn growing attention for their potential use in a host of biotechnological processes to benefit humankind, from ...

Hepatitis D Virus (HDV) Particle. Image Made According To A View Under Transmission Electron Microscope, Viral Diameter 35 Nm. This is the first part of a series on hepatitis D virus, a virusoid-like ...

Once the virus attaches to receptor clusters, it sends signals that make the cell wrap it in a clathrin coat and build an actin bulge, pulling the virus inward. The virus is then pinched off into a ...

In Europe, the pandemic triggered in 2020 by the SARS-CoV-2 coronavirus is now largely under control. But why this virus is able to spread so efficiently remains unclear. A team of researchers led by ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

The green wormlike structures covering the blue cell in this image are individual Ebola virus particles. This is the virus that causes Ebola virus disease (EVD), also known as Ebola hemorrhagic fever; ...
