The new front against antibiotic resistance
After Alexander Fleming discovered the antibiotic penicillin in 1928, spurring a “golden age” of drug development, many scientists thought infectious disease would become a horror of the past. But as antibiotics have been overprescribed and used without adhering to strict regimens, bacterial strains have evolved new defenses that render previously effective drugs useless. Tuberculosis, once held at bay, has surpassed HIV/AIDS as the leading cause of death from infectious disease worldwide. And research in the lab hasn’t caught up to the needs of the clinic. In recent years, the U.S. Food and Drug Administration has approved only one or two new antibiotics annually. While these frustrations have led many scientists and drug developers to abandon the field, researchers are finally making breakthroughs in the discovery of new antibiotics. On Jan. 9, the Department of Biology hosted a talk by one of the chemical biologists who won’t quit: Deborah Hung, core member and...
