Turritopsis dohrnii is a species of jellyfish that some scientists say can live forever by reverse aging, over and over again.
In a process called transdifferentiation, these jellyfish can transform their dying adult cells into new healthy cells.
Since they’re so hard to catch and keep in a lab, only a handful of scientists study how they do this. Their research may lead to insights about how to treat diseases like Parkinson’s by replacing lost or damaged neurons in the brain.
