Bony fish like the tiny zebrafish have a remarkable ability that mammals can only dream of: if you lop off a chunk of their heart they swim sluggishly for a few days but within a month appear perfectly normal. How they accomplish this -- or, more importantly, why we can't -- is one of the significant questions in regenerative medicine today.
