Microbial diversity is organised into operationally defined species. However, it remains unclear whether these, or finer-scale groups represent biologically meaningful units in natural communities. He...

Abstract. Broad-host-range IncA and IncC (A/C) conjugative plasmids propagate multidrug resistance in bacteria and mobilize chromosomal resistance islands,

Phage therapy is providing a benefit to a limited number of people. To date those who have received phage therapy typically have done so via an IND expanded access mechanism, colloquially referred to ...

Nature Microbiology, Published online: 30 September 2026; doi:10.1038/s41564-026-02498-xHybridization of wild and cultivated rice plants improves nitrogen use efficiency through microbiome re-domestication.

A diet–microbiome–host axis strengthens mucosal immune defences and reinforces host–microbiota mutualism.

A POLITICO investigation reveals more than 100 open records requests demanding documents from climate scientists nationwide.

The patterns and pathways of pathogen adaptation during chronic infections can reveal the gateways microbes must unlock to colonize and persist. In chronic lung infections of cystic fibrosis (CF) pati...

An expert at the University of Copenhagen said his team had been sharing its research with the company’s A.I. model, Claude, and that its new finding matched their work.

Using affinity purification-mass spectrometry, these authors identified the Healer system, a phage two-protein effector that repairs CRISPR-mediated DNA breaks via homologous recombination.

The American Society for Virology (ASV), American Society for Microbiology (ASM), and the Infectious Diseases Society of America (IDSA) are alarmed by the initiative of the U.S. Department of Health a...

The amoeba Incendiamoeba cascadensis demonstrates that eukaryotic life can withstand temperatures beyond what was thought possible and sheds light on molecular strategies for survival in extreme heat.

Abstract. Experimental evolution provides a powerful framework for dissecting how ecological interactions shape adaptive trajectories. Here, we evolved Kle

Plasmids drive bacterial adaptation, but how their diversity arises has remained unclear. Here, they show that in Staphylococcus aureus, mobile genetic elements repeatedly fuse and delete plasmids, re...
