Here's an interesting fact about nanotechnology: Did you know that scientists have developed nanoparticles called "nanoswimmers" that can be propelled through fluids using magnetic fields, allowing them to potentially deliver targeted cancer treatments and navigate through the human body in a non-invasive manner? These tiny robots are only a few micrometers in size and are designed to mimic the movement of bacteria and other microorganisms.

Did you know that there is a type of jellyfish called Turritopsis dohrnii, also known as the "immortal jellyfish, " which can transform its body into a younger state through a process called transdifferentiation, essentially making it immune to aging?
