Northwestern professors never cease to do ground-breaking research in obscure areas. Ernest Moore, a research professor of molecular pharmacology, discovered how zebrafish may help improve the lives of 12 million Americans and more than 400,000 troops who have returned from Iraq and Afghanistan. Experiments on the fish are helping Moore develop a drug that treats the loud ringing in the ears known as tinnitus, which cost the U.S. government $539 million in war-related disability payments in 2006. This study may even have further-reaching implications than speed-dating.
