The hunt for new antibiotics


We have not discovered a new group of antibiotics for over 30 years, but the ones we use are becoming less effective as bacteria become resistant to them. It is estimated that 700,000 people are killed each year by antibiotic-resistant bacteria.

Researchers at the University of East Anglia are studying the antibiotics that are produced by leaf-cutter ants to control pathogens in their fungal gardens.
