CBS News reports on another advancement in the field of regenerative medicine. Cells in the ear that normally do not regrow have been successfully regenerated in adult guinea pigs. This is a good companion to recent successful trials on regeneration in the eye in Asia. We can hope that as more specific applications of regenerative medicine are demonstrated, opposition to these new tools of medicine will vanish. There's certainly all too much opposition to stem cell therapies right now, and this is blocking rapid advances towards healthy life extension medicine.
