We’ll understand if you’re puzzled by the eerie image below. It’s a tiny piece of the Lassa virus, which can double a person over in pain, make their head swell and, in some cases, quickly result in ...

For the first time, researchers at Umeå University, Sweden, can now show how the dreaded poliovirus behaves when it takes over an infected cell and tricks the cell into producing new virus particles.

Retroviruses are viruses that have evolved the ability to write their genetic code into a cell's own DNA. The most ancient ...

Four years ago the first modern electron microscope was exhibited by the Siemens & Halske A.-G., in Berlin (TIME, June 6, 1938). Two years ago the R.C.A. Laboratories completed the first commercial ...

The film discusses the nature of viruses, including their structure, reproduction, and the diseases they cause. It explains how viruses are incredibly small and require a host cell to survive and ...

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 ...

Researchers who work with bacteriophages -- viruses that eat bacteria -- had a pleasant and potentially very important surprise after treating samples to view under an electron microscope: they had ...

A new way of imaging frozen biological samples using electron microscopy is providing new glimpses into the nanoscopic world of cells. Images reveal bent in-vitro tubulin microtubules next to and in a ...

For the past 22 months we’ve seen coronavirus images everywhere, but researchers in Spain have now found that the choice of image determines how we think about the information that’s being presented.
