Mystery CRISPR unlocked: A new ally against antibiotic resistance?

CRISPR-Cas systems have revolutionized biotechnology by offering ways to edit genes like a pair of programmable scissors. In nature, bacteria use these systems to fight off deadly viruses. A recent international collaboration led by the University of Copenhagen has shed light on the most enigmatic CRISPR-Cas systems; the type IV system. While these atypical systems do not cut genes, their unique functions show promise in our fight against antibiotic resistance.
