About

No organism lives forever. The length of time animals and humans live is influenced by their genes. Scientists have made astonishing discoveries concerning the role of genetics in determining life span and this holds promise of extending the lives of animals and humans. This program explains Genetics, DNA and genetic theories of aging. It illustrates the genetic processes behind cellular aging and shows how genes affect life span. Discover the reasons why cells age and why a certain enzyme can effectively turn back the hands of our "biological clock."

Approximately 12,000 babies are born annually in the United States with a hearing impairment. With impressive advancements in technology, cochlear implants are giving these children the ability to hear. A cochlear implant is a small, complex electronic device that can provide the sense of hearing to patients who are profoundly deaf or are severely hard of hearing. The cochlear implant helps patients hear by using electrodes that stimulate the remaining auditory nerve fibers in the patient's cochlea. The electrical sound information is sent through the auditory system to the brain for interpretation. In this program, students will learn about the benefits of cochlear implants and how the ear works, as well as the different parts of the inner and outer ear.
