University of Toronto researchers have made the first discovery of a virus that infects Legionella pneumophila, the bacteria ...

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 ...

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, ...

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.

Cryo-electron microscopy and tomography are transforming structural biology, offering unprecedented insights into ...

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.

Viruses have no metabolism of their own and must therefore infect host cells in order to replicate. Contact between the virus and the cell surface is a crucial first step, which can also prevent ...

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, ...
