Hi, we've got three stories from Curiosity.com to help you get smarter in just a few minutes.

I'm Cody Gough.

And I'm Ashley Amer.

Today you'll learn about a literally immortal jellyfish that could teach scientists how to live forever.

The best way to argue with your partner, and weird alternatives to black holes since they might not exist.

What's that to satisfy some curiosity?

If you could be immortal, Ashley, would you do it?

Oh boy, probably not. I mean, I'd like to live longer but I don't know if I would want to live forever.

Yeah I mean living forever with the option not having to die from old age but still being

killable. Yeah maybe that's it. Well, the secret to immortality,

scientifically speaking, like IRL in real life, might be in the genes of a jellyfish that is literally immortal.

Literally.

Literally.

There's a jellyfish called the teratopsis dorinae and it basically reboots itself

when it's about to starve or die from taking too much physical damage.

So usually T-Dor and I reproduces the traditional way with sperm and eggs, but when it's

faced with starvation or physical damage or another crisis, it transforms its existing cells into a younger state

through a process called trans-differentiation. That's also what scientists use to

turn stem cells into other human cells. During trans-differentiation, the jellyfish latches

onto a sturdy surface, turns into a blob-like form, and then transformed into a colony of polyps.

And a polyp is the earliest stage of its life. So basically you've got an

animal that can revert itself into a sexually immature stage after it has reached
