The world’s first human trial uses stem cells to regrow damaged inner ear nerves, aiming to permanently reverse biological hearing loss.
For decades, medical science has treated hearing loss as an inevitability of ageing or trauma.
While animals like birds and fish can effortlessly regenerate the delicate sensory cells and nerves inside their ears, humans are locked out of this biological luxury.
Once the intricate neural pathways between our inner ear and the brain are frayed by loud noise, illness or time, they are gone for good.
Until now.
