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
Bacterial cells before phage infection (left) and after (right). The virus replicates itself inside them and leads to the explosion of the cells and the spilling of their contents (in red - the bacterial DNA spilled from the cell)

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

The omicron variant contains many mutations in the spike protein, which facilitate the penetration of the virus into cells

A virus from the corona family that affects horses was diagnosed for the first time in Israel

The equine corona virus is a close relative of the corona virus which has caused widespread morbidity in the world in the last year (COVID-19). In this family, called beta-coronavirus, there are also other animal and human corona viruses, among them the bovine corona, which is also found in cattle in Israel

This is according to a joint study by Tel Aviv University and Hasharon Hospital (Rabin Medical Center). The researchers estimate that in the case of repeated exposure to Corona, those who recover from the disease may be protected from a second illness - but it is possible that they may still carry the virus and infect others

Researchers offer a new approach to dealing with the corona virus: putting the immune system into action even before the body is attacked

The researchers actually suggest increasing the power of the innate immune system - the first line in the fight against the virus, before the acquired immune system (specific to a particular pathogen) comes into action.
