Injection of "dancing molecules" gets paralyzed mice walking in 4 weeks

• By Michael Irving

In a new breakthrough study, researchers at Northwestern University have developed a gel containing "dancing molecules" that allowed paralyzed mice to walk again four weeks after a single injection.Neurons in the spine transmit signals between the brain and muscles, so damage to these can make even simple movements difficult or impossible. To make matters worse, the central nervous system has very limited capacity to repair itself, meaning paralysis is often permanent.
