Odd but intriguing research is underway at Colorado State University. Engineers are developing a mouth piece that can transmit the sensation of sounds to the tongue.
As anyone who has savoured a fine meal knows, the tongue is rich with sensory nerve cells. What if those cells could also be used transmit sound, or at least an interpretation of sound, to the brain bypassing the ears completely?
That’s concept the CSU researchers are working on and they produced this video to show how it might work.
Canadian Prime Minister Justin Trudeau led commemorative services this week to mark the 100th anniversary of The Battle of Vimy Ridge in World War 1.
