(Phys.org) —The mammalian auditory system is one of the most sensitive detectors found in nature. Two kinds of cells, the inner and outer hair cells, work together to transduce mechanical vibrations into action potentials. ...
(Phys.org) —A team of researchers made up of members from the U.S. and Canada has found that two species of fish that live in caves in the eastern and central parts of the United States have suffered hearing regression ...
Normal development and function in multicellular organisms relies on tight control of cell growth, yet surprisingly little is known about how such control is achieved. Although some promoters of growth have been identified, ...
