An analysis of the bones and teeth of ancient mammoths (Mammuthus) has identified some of the microorganisms that lived in ...

Using metagenomic screening — a technique for sequencing genetic material in samples that contain genomes from a mixture of ...

Bacteria have long been a key source of lifesaving antibiotics, but most species cannot be grown in the lab—leaving their ...

The giant DNA loops were discovered through a careful study of saliva samples from 56 volunteers, with further tests ...

Scientists have uncovered microbial DNA preserved in mammoth remains dating back more than one million years, revealing the oldest host-associated microbial DNA ever recovered. By sequencing nearly ...

Most bacteria cannot be cultured in the lab—and that's been bad news for medicine. Many of our frontline antibiotics ...

Researchers have discovered previously unknown antibiotic resistance genes using a new method that is capable of isolating ...

More than a decade ago, scientists harnessed a bacterial molecular machine that identifies and cuts specific sections of DNA, ...

Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Centre have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic ...

Certain bacteria typically found in the mouth and throat may be a trigger for heart attacks, recent research suggests.

The researchers analyzed 483 mammoth remains, mostly molars but also tusks and bones. The oldest samples are 1.1 million years old and belonged to a steppe mammoth — a species that later gave rise to ...
