T. Albet,a Deafness Research UK research fel-low at the UCL Ear Institute,together with scientists at the University of Cologne,shows that fruit flies have ears which mechanically amplify sound signals in a remarkably similar way to the senso- ry(感觉的)cells found in the inner ear of vertebrates(脊椎动物)including humans. The finding means that the wealth of genetic techniques already available to study the fruit fly can now be used to target how the ear works.第6题:
