a variant of the type I-E CRISPR-Cas system, providing insights into its DNA recognition and cleavage mechanisms. The study, published in Nature Communications, was conducted by researchers from ...

As a result, recruitment of Cas3 by the Csy complex is inhibited, thus effectively preventing the degradation of phage DNA by the CRISPR/Cas system. Cas3 plays critical roles during the process of ...

CRISPR places an entirely new kind of power into human hands. For the first time, scientists can quickly and precisely alter, delete, and rearrange the DNA of nearly any living organism ...

A new genetic technology called CRISPR may enable scientists to make permanent changes in a person's DNA. Here's everything you need to know: It's a revolutionary gene-editing technique that ...

Shelby is an assistant editor for The Scientist. She earned her PhD from West Virginia University in immunology and microbiology and completed an AAAS Mass Media fellowship. View Full Profile. Learn ...

Early reports have demonstrated that CRISPR effectively excises integrated human immunodeficiency virus type 1 (HIV) from cells. 1,2 For Michele Lai from the University of Pisa, these studies raised ...

Carl Zimmer recently reported in The New York Times about a new way Crispr could be used in new ways. “The groundbreaking thing about this work is that it now opens up the RNA world to Crispr ...

The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell. After that, the next step in CRISPR gene editing is usually to alter that piece of DNA. However ...

Another priority in the CRISPR field is improving the safety of gene editing. The first generation of gene editing technology makes double-stranded breaks in DNA, which raises the risk of ...
