Is THIS the key to restoring loss of smell? Scientists are developing an implant that zaps the BRAIN when it detects odours

Whether a person has lost their sense of smell from Covid, a traumatic brain injury or invasive surgery, scientists hope they may soon have a way to fix it.

That's because they're developing an implant — similar to one currently used to improve hearing — that zaps the brain when it detects odours and brings back a person's ability to smell.
