Mice with Second Sight
A news item reports that researchers at the Schepens Eye Institute have succeeded in regenerating an optic nerve in mice.
The research reached that stage by producing strains of mice that were genetically manipulated to not turn on a nerve growth inhibiting gene and also with reduced glial cell activity in the brain. So this is nowhere close to being made into a treatment for people, but it does give some information for directing lines of research toward that end.
