This synthetic stingray is made of gold, silicon and live muscle cells from a rat. Scientists use pulses of light to guide its propulsion.

Synthetic stingray, which has been created by scientists, is propelled from living muscle cells and is tightly controlled by light, as reported by a team in the journal science.


The researchers said that it will be possible to create an artificial heart through the same technique.


Kit parker, a bioengineer, and physicist at Wyss Institute of Harvard University reported that he wants to create an artificial heart, but it is not possible to move from scratch to a complete heart overnight.


Artificial hearts created in the past have been made of mechanical pumps. Parker said that Artificial Heart developed from living muscle cells is known to behave just like a natural heart and has the tendency to change and grow over time.


Nature made the heart the way it is designed for a reason and scientist is trying to replicate the functions as much as they can.


Parker explained that a stingray may be different from the heart. But the two require getting over the challenge that involves motion and fluid. The stingray has to be able to propel itself in the water while a heart has to move blood in the circulatory system.

People will likely become uncomfortable by using artificial stingray due to the questions raised about machines turning living organism.


The artificial ray is not an organism because it cannot grow, reproduce nor adapt. A scientist should be looking at this possibility as they research further into projects like this.


Dabiri says they want to make sure that the ethical issues are adequately catered for.
