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

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 specimens. Now, ...

This is a preview. Log in through your library . Abstract This paper examines the vital role played by electron microscopy toward the modern definition of viruses, as formulated in the late 1950s.

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.

A recent re-emergence and outbreak of Mpox brought poxviruses back as a public health threat, underlining an important knowledge gap at their core. Now, a team of researchers lifted the mysteries of ...

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 ...

The phenomenal new electron microscope (TIME, Dec. 14, 1942) has been taking a good long look at hitherto invisible objects. In the last two issues of the Journal of the American Medical Association, ...

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 ...

File photo: This 2003 electron microscope image made available by the CDC shows mature, oval-shaped monkeypox virus particles, left, and spherical immature particles, right. (Cynthia S. Goldsmith, ...

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 ...
