This research investigates how cells repair dangerous DNA double-strand breaks through the non-homologous end joining pathway. By identifying key proteins involved in this error-prone repair process, the work reveals new opportunities to sensitise cancer cells to radiation and chemotherapy, potentially improving treatment outcomes for aggressive cancers.

A hidden evolutionary arms race unfolds between bacteria and the viruses that attack them. By understanding how bacteria cut and rearrange DNA through recombination, researchers can harness these mechanisms for precise gene editing. This work could enable powerful new treatments for genetic diseases, helping patients like the first personalised-therapy recipient, KJ.
