This paper examines the vital role played by electron microscopy toward the modern definition of viruses, as formulated in the late 1950s. Before the 1930s viruses could neither be visualized by ...

The Trump administration’s actions on NIH gain-of-function research have raised concerns among scientists, who argue the move ...

Viruses are apparently no exception to the dog-eat-dog world that is nature. In a recent study, scientists have found evidence that some microscopic organisms actively feed on viruses.

Enveloped viruses were more likely to undergo cross-species transmission than nonenveloped viruses. It was noted that enveloped viruses tend to have a higher proportion of zoonotic spread than non ...

These viruses, however, are not the kind that will give you the common cold or flu (or worse). Called bacteriophages, or phages for short, they are the natural enemy of bacteria.

It was a record year for dengue fever, a disease transmitted by mosquitoes. The Americas have amassed about 12.7 million cases as of early December. That’s about 90 percent of the roughly 14 ...

DeLong and his team wanted to see whether there might be microorganisms that could survive on viruses alone. “We thought that could be true,” DeLong said, but no one had shown it. So he kicked off his ...

As many as 13 viruses have been discovered in the permafrost. While the threat of ‘zombie viruses’ is real, some scientists say there are still many unknowns about how they could affect humans.

Influenza viruses can use two ways to infect cells Date: July 18, 2024 Source: University of Zurich Summary: Most influenza viruses enter human or animal cells through specific pathways on the ...

Moreover, the downregulation of the miR-17 levels in EVs reduced the antiviral activity of TLR3-stimulated EVs against human nasal epithelial cells infected with any of the three common cold viruses.
