The dangers of antibiotic overuse have become increasingly clear in recent decades. Excessive use accelerates the evolution of bacterial resistance to antibiotics, raising the alarming prospect of ...

If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and the middle. Is everything packed? What time should we leave? Will there be ...

Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.

Archaeal DNA replication combines features of bacterial and eukaryotic systems within a unique framework adapted to extreme environments and diverse genome architectures. Initiation typically occurs ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...

Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called ...

PHILADELPHIA — Deep in the mangrove swamps of the Caribbean lives a giant bacterium with a surprise trick for organizing its DNA. Thiovulum imperiosus wraps its genetic material in membranous fingers, ...
