The rise of antibiotic resistance among common infectious bacteria is a worrisome health threat that has many scientists looking for a solution. Jennifer Hines, Ph.D., professor of chemistry and biochemistry at Ohio University, is one of the few looking to ribonucleic acid (RNA) structures for new drug discovery. Her research group is studying a key regulator for bacterial gene expression made up of RNA, called a riboswitch, that could be crucial in designing new drugs to kill bacteria.
