A reliable clock for your microbiome

For all the attention the human microbiome has been getting over the last few years, one aspect of such research rarely makes headlines: the difficulty of observing how it changes over time in response to various stimuli. ...

The Swiss Army knife of gene editing gets new control

When researchers want to edit, activate, or silence a gene in any living organism, from bacteria to humans, they often turn to CRISPR/Cas9, a complex of RNA and protein that can act like a genetic Swiss Army knife.

The argument for sexual selection in bacteria

The evolutionary pressure to pass on DNA can produce behavior that otherwise makes no sense in a struggle to survive. Rams bash heads in fights over females; peacocks grow elaborate tail feathers that attract mates and predators ...

Analysis reveals key gene for bacterial infection

To successfully infect their hosts, bacteria need to evade the host immune system in order to reproduce and spread. Over the course of evolution, hosts—such as humans—develop increasingly sophisticated defenses against ...

Diabetes impairs multipotent stromal cell antibacterial activity

A new study reveals that the multipotent stromal cells (MSCs) of persons with diabetes have diminished capacity to fight off bacterial infection, providing new understanding into the basis of diabetes-associated immune dysfunction. ...
