Invertebrates (animals without backbones) can repair their own nerve axons (the extensions from nerves that communicate with other nerves), and the researchers have found out how this works, and have been able use the techniques to repair damaged nerves in rat’s legs.

It’s still early days but if this could work in humans it could allow people with injured nerves to recover in days or weeks, rather than months or years.
