Scientists inserted disco ‘strobe lights’ into jellyfish to see how they function without brains


Jellyfish may be brainless, yet they can do surprisingly complex things with their simplistic nervous systems. Now, by fiddling with the genes of jellyfish, researchers have devised a way to spy on the animals’ inner workings. 

In the new study, the researchers created a model using the jellyfish species Clytia hemisphaerica, a transparent, umbrella-shaped jellyfish with a tube-like mouth at its center. The teeny jellyfish grows to be only 0.4 inches (1 centimeter) in diameter, meaning the team could place the whole jellyfish under the microscope and observe its entire nervous system at once.
