Superbugs and antimicrobial resistance (AMR) are a huge global health problem. So what do you do when your medicines are ineffective? The answer for some researchers is to build their own biological weapons. A team including experts from the University of Oxford in the UK has developed a way to create specialized cells that hunt down and kill drug-resistant germs.
