Scientists make paralysed rats run again: "'We are now designing neuro-prostheses, arrays of electrodes that fit like a second skin between the vertebrae and the spinal cord,' Courtine explained. A strip measuring three centimetres (1.2 inches) long and one hundredth of a centimetre thick, the device is described as 'minimally invasive' because it does not penetrate into the spinal cord. Courtine and colleagues are currently testing the neuro-prostheses on rats, and expect to have an interface for humans within four years. The new technique is designed to help patients with incomplete but severe injuries, such as those who cannot walk independently."

What a wonderful thing it would be if paralyzed people could walk again. And this technology doesn't involve stem cells as far as I can understand.
