Colorized scanning electron micrograph of cells heavily infected with COVID-19 (SARS-CoV-2) virus particles (orange). The inset is an artist’s rendition of a single virus with its spike proteins — the ...

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, ...

Modern laboratory techniques for the detection of novel human viruses are greatly needed as physicians and epidemiologists increasingly deal with infectious diseases caused by new or previously ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...

Scientists have caught a virus in the act of infecting a cell, and captured images of the action in real-time and three dimensions. This work was made possible by combining a technique called lattice ...

Current calibration methods rely on artificially constructed DNA structures or specific cellular features, each with significant drawbacks. DNA-based rulers require complex chemical synthesis and only ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...
