Researchers have discovered giant DNA structures in oral bacteria, and data hint they could influence the function of your immune system.

Some genetic disorders—such as cystic fibrosis, hemophilia and Tay Sachs disease—involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.

Scientists dug into paleofeces for a new study, learning some very intimate details about how long-ago people lived.

An analysis of the bones and teeth of ancient mammoths (Mammuthus) has identified some of the microorganisms that lived in the animals’ mouths and bodies more than one million years ago. The study, published in Cell on 2 September, describes the oldest ...

For billions of years, bacteria have waged an ongoing arms race against viruses, evolving many defense mechanisms against the infectious invaders

DNA from King Richard III’s mouth reveals his oral microbes, hinting at his health, diet, and life in the 15th century.

Scientists at The University of Texas at Austin have developed a revolutionary gene-editing method using bacterial retrons that can correct multiple disease-causing mutations at once. Unlike traditional tools limited to one or two mutations,
