A small striped fish is helping scientists understand what makes people susceptible to a common form of hearing loss, although, in this case, it’s not the fish’s ears that are of interest. In a study published in the Feb. 29 issue of the journal PLoS Genetics, researchers at the University of Washington have developed a research method that relies on a zebrafish’s lateral line—the faint line running down each side of a fish that enables it to sense its surroundings—to quickly screen for genes and chemical compounds that protect against hearing loss from some medications. The study was funded in part by the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health.
