Researchers find traces of SARS-CoV-2 in the stool and blood of kids with the post–COVID-19 inflammatory disorder, and signs of increased intestinal permeability.

Researchers report chemical and molecular signatures of microbial activity from millions of years ago in mineral samples from abandoned mines in Sweden and nearby countries.

Projects aimed at collecting big data about the ocean’s tiniest life forms continue to expand our view of the seas.

With multiple microbiota therapeutics in the pipeline for recurrent Clostridium difficile infection, clinicians foresee a shift in treatment options for the condition.

The researchers found thousands of species not previously documented.

A controversial idea from the mid-20th century is attracting renewed attention from researchers developing theories for how cognition arises with or without a brain.

Historical and modern experiments have hinted that unicelluar organisms can learn from their experiences, but the idea still has its critics.

Explore how microbes shape health, disease, and the world beyond

In a new study, human and mouse cells recognized only one in five bacterial species collected from more than a mile below the Pacific Ocean’s surface.

With modern technologies unearthing novel bacterial and archaeal species by the dozens, hundreds, or even thousands, manually naming them all is no longer practical, scientists say.

The mysterious DNA sequences appear to help bacterial cells spot when they’ve been infected with viruses—and prompt those cells to self-destruct.

Early investigations of the microbial communities in and around sunken boats reveal that there are patterns to where bacteria settle.

The discovery puts a nail in the coffin of a long-held assumption about the limits of where the essential process can occur.

Tiny doses of maternal poo mixed with breast milk and given to Cesarean-born infants makes their gut microbiota resemble those of babies born vaginally.

Researchers Jason Gill and Paul Turner will discuss their work on bacteriophage therapy to treat drug resistant bacterial infections.

The microbes had survived on trace amounts of oxygen and were able to feed and multiply once revived in the lab.

Heather Jordan and Jennifer Wargo will discuss how metagenomics studies help uncover new and medically relevant functions of the human microbiome.

The BioCollective, a company that transforms whole stool samples into microbial metadata, is developing the US’s first national microbiome reference material.

The use of yeast artificial chromosomes has enabled the rapid genetic reconstruction of the novel coronavirus.
