Scientists from the California Institute of Technology and Harvard University made an artificial jellyfish with a single pulse of electricity. "It's alive! IT'S ALIIIIIIIIIVE!" Known as the medusoid due to its umbrella shape, the jellyfish made out of silicone uses a rat's heart muscle to recreate the pumping motion familiar to a moon jellyfish.
So, what does this mean to human beings? Well, this "medusoid tech" can be used to serve as a pacemaker in our body, powered by our natural nutrients. In short, we can might be able to make improved artificial hearts. What does this mean to sci-fi writers? Well, the skies the limit. "Think big on a galactic level," right? :P
As of now, the cyborg has limited movement, but scientists are already working on giving it better maneuverability. Check out more info here at News Scientist.
