Bacteria

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
The experimental setup: microfluidic channels with a diameter of 1 micron in which E. coli bacteria were grown for several generations using a variety of fluorescent markers. These markers make it possible to follow important events in the bacterium's life cycle at the single cell level

How does a bacterium know it's time?

An examination of known growth laws that were discovered recently, led to the discovery of new growth laws
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.

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

And even so, the bacterium moves and moves

For many years, researchers from all over the world have debated the question: how do bacteria move? A new international study sheds light on the movement mechanism of those microscopic creatures, through a reexamination of the proteins that make them up

Micro-robots swim in the lungs and kill bacteria

Nanotechnology engineers at the University of California San Diego have developed tiny robots - micro-robots, in their full name - that are able to swim inside the lungs, reach the bacteria that cause pneumonia, kill them and reverse the damage they do to the body
Schematic diagram of the bacterial operon (top) versus the eukaryotic transferron (bottom). According to the researchers, instead of "beads on a string" a kind of genetic "stroke-na" game developed during evolution that allows using the same "letters" - that is, messenger RNA molecules originating from genes located on different chromosomes - to create different "words", i.e. different transferrons

How did evolution overcome the lack of order in the storage of genetic information in the transition from bacteria to more developed creatures?

And what does it have to do with the Genesis mission that crashed on the moon? For 50 years, government organizations adhered to the accepted rules and laws for self-defense of the solar system against terrestrial pollution. Now they are being joined by an increasing number of commercial space missions. How to enforce the law on them?

This is how bacteria turn the cells of the immune system into an all-inclusive hotel: bacteria swallowed by macrophages sometimes succeed not only in surviving but even thriving inside them, as if they were incubators that help spread the infection in the body - and not soldiers in the service of the immune system
