New options for vaccine development against hepatitis C virus

A study conducted at the Faculty of Medicine of Bar Ilan University in Safed discovered antibodies found in the bodies of people who have recovered from the virus. The research insights will lead to the development of innovative therapeutic approaches, also for other viral diseases

How might a biochip save us from the next pandemic

Cornell University has introduced a bioelectric device that can quickly detect harmful variants of Corona, and possibly other viruses as well. This chip-based device uses a biomembrane to simulate the process of infection development
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
A specific and particularly successful phage named PASA16 discovered by the Israeli center treated 16 patients, most of them severe, and it demonstrates the high potential effectiveness of treatment in dealing with challenging and antibiotic-resistant Pseudomonas aeruginosa infections.

Innovative treatment with phages in antibiotic-resistant infections has over 80% success rate in Pseudomonas infections

A new international study on treatment using the PASA16 phage (a virus that kills only bacteria), showed a success rate of over 80% and gives hope for a beneficial treatment for resistant infections

On dormant viruses and protective proteins

New discoveries about how the result of infection with a virus from the herpes family is determined and where dormant viruses may hide in the body

The biology of depression

Degeneration of the cells of the immune system in the brain may be the biological cause of depression, and there may be substances that can restore these cells - and be antidepressants

Viewing viruses in detail

Researchers demonstrated the benefits of a natural, non-radioactive dye by observing viruses at the nanometer level. The innovative material is a structurally stable material and is a natural molecule with a longer shelf life

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

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 by our team of researchers

Is Omicron more contagious than Delta? A virus evolution expert explains what researchers know and don't know

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

Bacteria, people, and the numbers in between

The variety of physical features, the size of the genomes and the lifestyles of viruses all make their classification difficult. New research uses protein folding as evidence that viruses are living creatures that belong in their own branch of the branch of life. [Courtesy of Julie McMahon]
