I don't know if A Beautiful Mind counts as it's a true story. It's not just an story with an AIYH ending - it's what really happened (well more or less anyway).
Not quite. It's just an alternative way of transmitting sound to the cochlea. Normal hearing aids transmit sound through the ear canal and middle ear to get to the cochlea, while this bypasses that particular pathway by transmitting sound directly to the cochlea via a bone conducted pathway. Either way the hair cells are exposed to the same level of sound.
As for hearing loss caused by hearing aids, this is extremely uncommon. Modern hearing aids amplify sound nonlinearly, meaning that they amplify soft sounds more and louder sounds very little if at all. They also have maximum output levels that are lower than the level of noise that is required to cause damage to the hair cells.
Well Nobody, until such a thing exists people with hearing losses are going to have the need for sound amplification. Or would you rather they wait around until a scientific breakthrough that can regenerate hair cells so as to keep you happy?
This would be good for people with absent or malformed ear canals who can't wear conventional aids, or for people with severe middle ear pathology. At the moment, the only device for them is a bone anchored hearing aid that requires a screw to be surgically implanted into the skull.
I have worked with lab rats before and even they aren't treated nearly as badly as this article is making out. We would have been shut down if we were mistreating them like that. The conditions we kept them in were no worse than any domestic pet rat.
I wonder why they use beagles? I know they use cats for vision research as their visual acuity is very similar to ours in daylight. I know they use guinea pigs for hearing research as their inner ears are particularly similar to ours. I know they very occasionally use chimps and other apes/monkeys obviously because they are similar to humans in many ways. They generally use rats the rest of the time, which are far more similar to humans than you would thinks. So why beagles?

The similarities between the wolf skeleton and that of the thylacine are a good example of convergent evolution.

Bull**t. How is it more beneficial?
