Research on hundreds of babies finds the delivery method is linked with a greater abundance of taxa more frequently seen in hospitals.

Neither the maternal microbiome nor housing conditions appear to permanently alter which microbes remain in the animals.

The authors of a new study find no evidence for bacteria in the placenta, but others in the field question their interpretation of the data.

Researchers seek to untangle the biological mechanisms linking resident microbes to our hearts—and to harness them therapeutically.

Research in mice and humans is beginning to establish a link between the composition of microbes in the gut and immune responses to tumor cells, but the mechanisms are not yet clear.

Molecules produced by resident bacteria and their hosts may signal immune cells to attack the body’s own tissues.

In a study of nearly 400 breastfeeding mothers, researchers find links between directly feeding the child and a more diverse microbiota, compared to milk from pumping.

Researchers find that it’s not just high-risk genes, but how children’s bodies respond to their own intestinal microbiota that relates to future diagnoses of type 1 diabetes.

Transposon mutagenesis give scientists a rare look at the most important interactions within microbial communities.
