Synthetic vocal cord gel gives people their voices back

People with scarring in their vocal cords can find themselves with difficulties speaking, or even a complete inability to speak. But a fancy new gel from the smart folks at MIT and Harvard could give them their voices back.

The synthetic gel, known as polyethylene glycol (PEG), is very flexible and works much like real vocal cords. By simply injecting it into someone's vocal cords (yikes!), it can help restore their voice by mimicking the elasticity of their vocal cords and helping restore vibration to those stiffened by scarring.

By classifying it as an injectable medical device rather than a drug, they're hoping to get it to market relatively soon. And for those unable to speak, it couldn't come soon enough.
