Near-weightless conditions can mutate genes and alter the physical structures of bacteria and phages, disrupting their normal ...

The viruses devise ploys to break into bacterial defenses. Bacteria, on the other hand, strengthen their defenses so that ...

On the ISS, viruses can still infect bacteria, but the process slows and pushes both organisms to evolve along different ...

Viruses that infect bacteria can still do their job in microgravity, but space changes the rules of the fight.

The International Space Station (ISS) is one of the most unique environments where life has ever existed, out in the low ...

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua W. Modell ...

Pseudomonas bacteria infected by different mutations of a jumbo phage. The dot in the middle is the shield created by the phage to protect its DNA after it has infected the bacterial cell. Image by ...

This is a summary of: Liu. H. et al. Viral RNA blocks circularization to evade host codon usage control. Nature https://doi.org/10.1038/s41586-025-09809-y (2025).

Scientists estimate that the earliest biological entities began to appear on Earth more than 4 billion years ago. "There was a sort of primordial soup from which certain organic molecules were formed.

Jumbo phages belong to a group of viruses that attack bacteria. They inject their DNA and then reproduce by taking over the cell’s DNA-copying machinery. Eventually, a phage makes so many copies of ...
