University of Toronto researchers have made the first discovery of a virus that infects Legionella pneumophila, the bacteria ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

Scientists built a model that allows them to diminish phage communities from a mouse gut microbiome -- and then bring them back -- without affecting the bacteria. On a test run of their model, ...

Cancer research has long looked at bacteria and viruses as separate tools for therapy. Now, researchers are showing that the two can actually work better together. A team of scientists has built a new ...

Scientists are looking toward a class of large viruses called jumbo phages as they develop new and more capable antibiotics.
