Scientists have discovered a new CRISPR mechanism with precise activity, expanding the potential applications of the existing CRISPR toolbox. The CRISPR ‘gene scissors’ have become an important basis ...

In nature, the best-known CRISPR system, CRISPR-Cas9, cuts any RNA or DNA it recognizes as foreign, and thereby protects bacteria from viral attacks. Another CRISPR system, one that is relatively ...

A novel CRISPR defense mechanism, unlike known nucleases, specifically destroys transfer ribonucleic acids (tRNA) that are vital for protein production to shut down infected cells. (Nanowerk News) ...

(Nanowerk News) The CRISPR-Cas gene scissors offer a wide range of potential applications, from the treatment of genetic diseases to antiviral therapies and diagnostics. However, to safely harness ...

In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally ...

CRISPR/Cas9 is a gene editing tool that has revolutionized biomedical research and led to the first FDA-approved CRISPR-based gene therapy. However, until now, the precise mechanism of exactly how ...

CRISPR functions as a programmable genetic memory system derived from bacterial immune defenses against viral infections. Guide RNA allows for rapid multiplexed targeting compared to older ...

Trace the timeline of CRISPR-Cas9 from its 2012 discovery to the latest AI-driven advancements and "N-of-1" clinical ...

The cryogenic electron microscope structure of the A4p-activated (green) CalpL protein filament (violet) from Candidatus Cloacimonas acidaminovorans (PDB ID: 9EYJ). CRISPR-Cas systems help to protect ...

Bacteria and their viruses, known as phages, are locked in an age-old arms race. To defend against phage attacks, bacteria have evolved sophisticated mechanisms to recognize and counteract invading ...
