Scientists have created a " cyborg " stingray which could lead to the creation of better artificial hearts . The robotic stingray , constructed using genetically engineered rat heart cells , responds to light in such a way that it travels through water in a similar manner to how a heart travels , using a circulatory system .

Scientists have created a "cyborg" stingray which could lead to the development of better artificial hearts. The robotic stingray, made using genetically altered rat heart cells, responds to light in such a way that it moves through water in a similar manner to how a heart pumps, using a circulatory system. Kit Parker from Harvard University's Wyss Institute said he had the idea after visiting an aquarium with his daughter.
