The genomes of phages—viruses that infect bacteria—are largely composed of "dark matter": genes that encode proteins whose functions remain unknown. Less than four years ago, a team led by Prof. Rotem ...

It’s long been known that antibiotics can disrupt the balance of bacteria in the gut, typically causing short-term symptoms like diarrhea. Some research suggests the disruption can last for several ...

Researchers reviewed evidence linking the vaginal microbiome to pregnancy health and spontaneous preterm birth, highlighting ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Scientists studying stranded pygmy sperm whales have uncovered three previously unknown genotypes of Helicobacter bacteria ...

In Michigan Tech's biology teaching lab, undergraduate students research potential cancer cures with help from the humble worm.

Millions of unknown microbial genes discovered in Antarctica’s ocean reveal a hidden ecosystem that may influence carbon cycling and climate.

A communication pathway between the brain and the gut may be integral to how well the brain holds on to memories ...

Scientists have uncovered the oldest known genome of the bacterium responsible for syphilis, revealing a previously unknown lineage that existed thousands of years ago in the Americas.

Scientists at the University of East Anglia (U.K.) have uncovered a hidden link between gut health and the immune system—all ...

Researchers have mapped a vast reservoir of drug-resistant genes in Indian sewage, identifying mobile DNA that helps bacteria ...
