Artificial Jellyfish Made From Rat Cells

It looks like a jellyfish. It swims like a jellyfish. But, the tentacled artificial creature above, dubbed the "Medusoid," is actually created by scientists at Caltech and Harvard with rat cells:

It is able to mimic the swimming movement of a jellyfish thanks to muscle cells from rat hearts which were implanted onto its silicon frame and grown into a pattern similar to the muscles of a real jellyfish.

By applying an electric current to a container of conducting liquid, the scientists demonstrated they could "shock" the muscles into contracting so that it began to move through the water.

I welcome our new Rat Jellyfish Silicon overlords and hope their subsequent uprising, and then enslavement of the human race goes smoothly.
