If you still remember that “Dear King Phillip Came Over For Good Spaghetti,” you’ll likely also recall the corresponding taxonomic ranks of biology: Domain, Kingdom, Phylum, Class, Order, Family, ...

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 ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

The discovery of Psychrobacter SC65A.3, isolated from the Scărişoara Ice Cave in Romania, is both a blessing and a curse.

Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of ...

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 ...

According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...

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 ...

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 ...
