What happens when natural selection, the most powerful process driving change in the living world, shapes artificial ...

The bacteria Acinetobacter baumannii (A. baumannii) is a haunting presence in many hospitals in the United States, where more than one in 100 patients are treated for A. baumannii infections. This ...

Everywhere you go, you carry a population of microbes in your gastrointestinal tract that outnumber the human cells making up your body. This microbiome has important connections to health in your gut ...

Bacteria are the most diverse organisms on Earth, with a number of species that’s difficult to quantify. They’re also incredibly old. Bacteria consist of a single cell. They do not have bones and are ...

Unlike most bacteria, Caulobacterales bacteria divide asymmetrically when they reproduce, which creates two cells that look different from each other (top part of the illustration). However, the ...

Evolution of bacterial pathogen populations has been detected in a variety of ways including phenotypic tests, such as metabolic activity, reaction to antisera and drug resistance and genotypic tests ...

A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis. University ...

Lines of bacterial genome sequences are made to evolve independently by introducing high-activity insertion sequences, each simulating decades of evolution in the wild in just weeks. The genome ...

Bacteria have evolved to adapt to all of Earth's most extreme conditions, from scorching heat to temperatures well below zero. Ice caves are just one of the environments hosting a variety of ...

The different species in the human gut microbiome change and evolve throughout a person's life and even across multiple generations. Studies show that gut bacteria often evolve rapidly, with new ...
