Summary:
Even humans can replace some damaged tissue in organs, such as the liver. But none can accomplish what the zebra fish, a common denizen of home aquariums, can do: regenerate their hearts. Biologists have long known about the zebra fish's cardiac ability, and now researchers think they have unlocked the secret of the process, which may provide essential clues for human heart repair.
Commentary: Maybe this finding can eventually lead to new methods for repairing damaged human heart muscle.
