Scientists in the US have created an artificial swimming jellyfish using heart cells. The scientists built the jellyfish replica using silicone as the base, and growing heart muscle cells harvested from the rats.

The team shocked the muscle cells into contracting using an electric current.

They then used electric current to shock the Medusoid into swimming with synchronised contractions that mimic those of a real jellyfish.

The swimming behaviour of the Medusoid closely mimics that of the real jelly-fish

So, what does this kind of technology hold for us in the future?

Even though this not creating life exactly. This kind of technology can help in creating artificial organs, like hearts and lungs. The pumping action of the jelly fish is actually quite similar to the heart.

The letter has been published as A tissue-engineered jellyfish with biomimetic propulsion in Nature Biotechnology.
