"When you see this symbol, you know you're watching a show that's educational and informational. CBS Weekend, weekend mornings on CBS. Hi, I'm Miranda Cosgrove and this is Mission Unstoppable. Coming up, this bug lover has a few tiny surprises for an appeal. We're going to be inhaling ants. And don't let your brain get hangry. So what should you feed your brain? Then are these notes from nature? That's no accident, it's engineering. Plus, these gems aren't just pretty, they're stuffed with science. Get ready to meet the scientists, inventors, and heroes who help make our world a better place. The future is here. The mission of ants. So hot right now. No, really. We sent an appeal to meet a scientist studying how ants are evolving to adapt to hotter urban temperatures. Check it out. Ants have been around since the time of dinosaurs. So you might think they'd have it all figured out by now, but the truth is they're evolving and adapting to an ever-changing world. And some scientists are trying to study how. So today, I'm meeting with entomologist, Sylvano Ross, who's studying how urban environments affect our insect neighbors."
