Viruses

The image illustrates the complex interactions described in your summary, and shows the complex choices that bacteriophages make between aggression and dormancy within their bacterial hosts, which are influenced by environmental cues and the health of the host. This represents the sophisticated mechanisms at work in bacterial and viral interactions as revealed by the study. Credit: The Science website via DALEE

How do viruses decide whether to stay friendly?

This is how the decision-making mechanism of viruses works

Researchers demonstrated the benefits of a natural, non-radioactive dye by observing viruses at the nanometer level. The innovative substance is a structurally stable substance and is a natural molecule with a longer shelf life than the radioactive substance most often used for this purpose, uranyl acetate

Researchers have identified more than 5,000 new viruses in the sea, including a missing link in virus evolution

  • No comments
An analysis of the genetic material in the sea identified thousands of previously unknown RNA viruses and doubled the number of systems, or biological groups, of viruses thought to exist, according to a new study published by our team of researchers in the journal Science
