Testing the evolution of resistance by experiment

When the first antibiotics became available 70 years ago, they were often described as miracles of human ingenuity, rather like plastics or bright permanent dyes, which were discovered at roughly the same time. Packaged in vials or pills, they seemed…



Microbiologists advance CRISPR research

The research of two Montana State University microbiologists into how bacteria fend off attacks from viruses is included in a new paper published in the scientific journal Nature. Blake Wiedenheft, assistant professor of microbiology and immunology in the College of…





Antibiotic’s killer strategy revealed

Using a special profiling technique, scientists at Princeton have determined the mechanism of action of a potent antibiotic, known as tropodithietic acid (TDA), leading them to uncover its hidden ability as a potential anticancer agent. TDA is produced by marine…
