Bacteria get invaded by viruses called phages. Scientists are studying how bacteria use CRISPR to defend themselves from phages, which will inform new phage-based treatments for bacterial infections ...
The CRISPR-Cas gene-editing system has long been the focus of research as a promising tool in genome editing. However, the emphasis has been on its underlying mechanisms and nucleases. In contrast, ...
Phages are ubiquitous particles that infect bacteria and archaea in all environments. In addition to lysing bacteria, phages ...
The microbial arms race, in which bacteria battle with each other, viruses, and other organisms for space and nutrients, has ...

SNIPE defense lets bacteria destroy phage DNA at the cell membrane
A single protein bolted to the inner membrane of a bacterial cell can shred a virus’s DNA before that genetic material ever reaches the interior. That is the central finding behind SNIPE, a newly ...
When the gene editing tool CRISPR-Cas9 rocketed to fame more than a decade ago, it transformed biotechnology. Faster, cheaper, and safer than previous methods, the tool helped scientists gain insight ...
Dozens of new discoveries reveal that defenses evolved by bacteria and viruses billions of years ago still define our own ...
Bacteria combat phage infection using antiphage systems and many systems generate nucleotide-derived second messengers upon infection that activate effector proteins to mediate immunity. Phages ...
CRISPR-Cas 9 is a gene-editing tool that made it possible to rewrite any organism's genetic code and tackle genetic diseases more effectively. Known as genetic scissors, CRISPR identifies a DNA ...
