Scientists resurrected 160-million-year-old proteins from extinct mammals; some were stronger against drug-resistant bacteria than modern human versions, raising new hopes for antibiotic research
Looking at the evolution of antimicrobial defenses, the researchers were able to pinpoint structural modifications that have made these peptides more potent and potentially develop treatments that work alongside existing antibiotics. There is an unexpected place scientists are looking for clues to the next generation of infection-fighting drugs: deep in the evolutionary past. At the…
