Rat Walks Again

This picture and story captures what's so heart-wrenching about the whole subject of animal experimentation. 

Rats with a spinal cord injury that left their hind legs completely paralyzed learned to walk again on their own after an intensive training course that included electrical stimulation of the brain and the spine, scientists reported on Thursday.

Obviously the rats don't just have this injury, they're injured by the experimenters. An awful thought, but it's easy to substitute an image of a paraplegic walking again for the rat ... and then this seems like a major victory.
