US cyborg jellyfish could be our new naval scouts

Currently, we have explored only 5-10% of the World Ocean, and to expand the scale of its study, we need to come up with something new. One of the curious and promising options is the use of cyborg jellyfish, which could carry sensors and constantly study the environment. To this end, Stanford University has developed a prototype control device for such creatures.

Usually jellyfish swim at a speed of 2 cm / s and try to maintain such a rhythm so as not to waste energy. However, it is known that they can develop a speed of 4-6 cm / s without any harm to themselves, but they resort to this only in extreme cases.

To control this aspect of jellyfish behavior, the scientists used a modernized pacemaker to generate electrical impulses in a strictly specified mode. They implanted it into the jellyfish, interrupting the natural signal of her body with an artificial one, which they accelerated three times. Obeying this command, the jellyfish increased the pulsation of its body parts and began to move three times faster.

During the experiment, scientists measured oxygen consumption and energy consumption - they only doubled. That is, movement with acceleration is not detrimental to jellyfish, they do not wear out at all. And if you pause, these sea creatures will be able to replenish their energy reserves, in the future, working indefinitely. Now researchers are faced with the task of learning how to control the direction of movement of jellyfish in order to create even more effective sea scouts.
