Mars Gets a Chopper A new Mars rover will take off for the red planet in 2020. The robot will drive around and search for any signs that microbes ever lived there. And it will travel to Mars with a tiny helicopter attached to its belly. The chopper’s body is about the size of a softball. It weighs less than 4 pounds (1.8 kg). Once the probe lands on Mars, the helicopter will detach and explore on its own. The air on Mars is much thinner than Earth’s air, so the blades will have to spin extremely fast to fly. But if the helicopter works, it could be a big help to researchers. They’ll be able to travel around the red planet without worrying about wheels getting stuck in the sand. Needed: Hippo…

the wonderful world of slime

Deep in the forest, a slug crawls along a rough branch. Behind it stretches a wet trail that glistens in the sun. But it’s not water—it’s a sticky path of slime. That slime helps the soft slug to glide smoothly over prickly trees and rocks. It keeps the slug’s body moist. It helps the slug digest food. It traps germs. Other slugs can sniff the slime trail like a message. In fact, that icky stuff is pretty useful. It’s true—the world is full of slime. Ooze, goo, spit, and mucus are everywhere you look. Almost every animal makes mucus—even fish! Some, like slugs, wear slime on the outside. Some make slime on the inside. And though slime might feel a bit gross, we couldn’t live without it. What Is Slime? So what is…

inspired by slime

Medical Mucus When doctors need to close up a deep cut, they often sew it up with thread or use metal staples. Ow! Is there a better way to help wounds heal? One group of inventors may have found one—in a slug. Snails and slugs use slippery slime to crawl around. But the dusky arion slug has a second kind of slime that it uses to protect itself. When threatened, the orange-brown slug oozes a watery mucus from its back. Within seconds, it sets into a sticky, stretchy gel. The result is a mouthful of syrupy goop for any animal that tries to eat the slug. Now doctors have copied the goop’s formula to make an ultra-strong medical glue. Unlike other kinds of glue, the slug glue can stick to wet places. It…

the sea’s super slime

Can you guess how the slime eel got its nickname? Step into your underwater time machine and travel back 500 million years, long before T. rex lived. Down at the bottom of the ocean wriggles a pale, eel-like fish, dining on bits of dead creatures. From up above, a shape suddenly looms. Huge jaws open, closer, wider, and... suddenly the skin of the helpless fish spews out a cloud of gooey, sticky slime. The goo fills the hunter’s mouth as it swims off in fright. The fish goes back to its dinner. If you return to the present and look on today’s sea floor, you’ll see almost the same slimy creature. Hagfish haven’t changed much in 500 million years. And why should they? They are champions at what they do best—making slime. What’s…

the snail’s two slimes

Have you ever watched a snail crawling and noticed a wet, slimy trail behind it? That slippery path helps the snail move easily over anything in its way. But snails don’t just slip along. They can also crawl up surfaces and stick to them. Why doesn’t the slime make them slide down? The answer is: snails make two kinds of slime! One slime is slippery. The second is much thicker and stickier—like glue. With this slime, a snail can stick to things without falling off. Snails make different kinds of slime depending on what they need to do. They can switch from slippery to sticky by changing the mix of slime ingredients from tiny glands in their skin. Snails keep their eyes and noses at the ends of long stalks. They eat by scraping…
