AI model uncovers a new CRISPR-like biological sys t em

Artificial intelligence has been billed as a tool that could accelerate discovery in the life sciences. Now researchers report that an AI model has helped identify a previously unknown biological system with similarities to CRISPR u2014 the bacterial defence mechanism that became the foundation of modern gene editing.nnThe finding is significant not only because of what was found, but because of how it was found. Rather than combing through databases by hand or testing candidate molecules one at a time in the lab, researchers used a model trained on vast quantities of biological sequence data to flag patterns that human eyes had missed.nn## Why CRISPR mattersnnCRISPR began life as an obscure curiosity: a set of repeating DNA sequences in bacteria that turned out to be part of an immune system for fighting off viruses. Bacteria store snippets of viral genetic code and use guided proteins to recognise and cut matching sequences when the invader returns.nnScientists realised that this search-and-cut machinery could be redirected at will, turning it into a programmable tool for editing genomes. Within roughly a decade, CRISPR moved from microbiology journals to Nobel recognition, agricultural laboratories and approved clinical therapies for inherited blood disorders.nnThat history explains the excitement around anything described as Read More
