Welcome to Curiosity from Discovery. This is my personal favorite place to get smarter in just a few minutes, and I'm Nate.

Welcome back, everybody, and if you are joining us today for the first time, hi, I'm Callie.

Today you will learn about a potential cure for diabetes, how ancient extinct volcanoes might provide a boost

for your cell phones, and why sharks and rays fling themselves out of the water.

All right, let's get started.

For the first time ever, a 25-year-old woman with type 1 diabetes has been cured.

Wait, okay, I know new treatments are always in the works for diabetics, but I didn't even

realize the potential cure was on the table. That would be earth-shattering if it's true.

Without a doubt. It's hard to overstate just how huge this could actually be. By some estimates,

nearly 12% of the American population has some form of diabetes. That's over 38 million people in America

alone. Odds are we all know

someone struggling with either type 1 or type 2 diabetes. Absolutely. And despite how common it is,

it's a pretty serious condition that requires constant blood sugar maintenance, constant attention

to diet, and like a lot of not-so-great symptoms. Right. Symptoms run the gamut from frequent urination to weight loss to

incredible fatigue, and the long-term effects can be devastating if it's not managed. We're talking

heart disease, nerve damage, kidney damage, the list goes on. Okay, so get to the good stuff.

Tell me about this miracle cure. Okay, so to explain how this works, it's important to get a little

technical.

The patient had type 1 diabetes, which isn't as common as type 2, but still affects millions

of people globally. With type 1, the immune system attacks insulin-producing islet cells in

the pancreas. Since the pancreas stops producing insulin, glucose or sugar, can't enter cells and stays put

in the bloodstream leading to high blood sugar levels. That's actually about the clearest
