Mini-Monsters with Multiple Heads Created in the Lab


The tiny, immortal hydra is a freshwater animal that can regenerate an entirely new animal from just the tiniest sliver of its body. Usually, it does this perfectly: One foot, one long skinny body, and one tentacled head.

But with a single genetic tweak, researchers can create monstrous hydras that sprout fully functional heads all over their bodies — appropriate for an animal named for an ancient Greek monster that had somewhere between six and nine heads.
