Spinal injuries that leave people paralyzed are currently incurable, one of the most feared and rehabilitating things that can happen to you. But researchers at Northwestern University are looking to change that for good, as they're hard at work on a new nanotechnology that could enable us to completely heal cut and severed spinal cords, allowing the previously paralyzed to walk again.

The tech takes the form of a gel that, when injected into mice with spinal cord injuries, allowed them use of their hind legs again after a mere 6 weeks. The procedure hasn't been tested on humans yet, but it's certainly a promising step forward towards a time where spinal cord injuries won't necessarily mean a life confined to a wheelchair.
