The discovery of peptides, enzymes, and other gene products that confer antibiotic resistance could give clues to how it develops.

Researchers engineer bacteria that deliver an anti-tumor toxin in mice before self-destructing. 

Bathyarchaeota undergo acetogenesis, generating organic carbon below the seafloor.

Diverse fungal species live in and on the human body.

The largely overlooked resident fungal community plays a critical role in human health and disease.

Next-generation sequencing has identified scores of new microorganisms, but getting even abundant bacterial species to grow in the lab has proven challenging.

The fungal and bacterial communities in household dust can reveal some details about a building’s inhabitants.

In some pathogenic bacteria, certain antibiotic resistance–associated mutations may also confer an unexpected growth advantage.

Extremophiles should not be viewed through an anthropocentric lens; what’s extreme for us may be a perfectly comfortable environment for a microbe.

Using ultraviolet light to disinfect drinking water may simply drive bacteria to dormancy, rather than kill them.
