Researchers at Caltech discovered that multiple unrelated viruses disable MurJ, a bacterial protein essential for cell wall construction, by locking it in a fixed position—revealing a potential new antibiotic target. The finding, published in Nature on February 26, 2026, highlights a promising strategy to combat drug-resistant bacteria as existing antibiotics become increasingly ineffective.
