nosy news

Hide and Reef The world’s largest coral reef is the Great Barrier Reef. It stretches for 1,400 miles (2,300 km) off the coast of Australia. Hundreds of divers and scientists visit it every year. You’d think we’d know all about it. But recently scientists found a surprise—another, unknown reef, right next door. The newly noticed reef is big and pointy. It stands about 1,640 feet (500 m) tall. That’s bigger than the Empire State Building. Researchers came across the pointy reef while they were working on a 3D map of the ocean floor. They sent a robot down to investigate. The diving robot, named SuBastian, sent back video of the reef. It’s the first new coral reef anyone has discovered in more than 120 years. NEED TO FLEE? TRY BARFING Have you ever eaten…

ants all around

I’m sure you’ve seen ants running around the sidewalk, disappearing into mysterious holes. Ever wonder what we do down there? First, let me introduce myself. Ants are not all the same, you know! There’s more than 16,000 different ant species. Ants live everywhere except Antarctica (so I don’t know why they call it that!). There are desert ants, forest ants, tropical ants, tree ants, even ants that live in nuts. How many ants are there on Earth? WAY more than people. A million billion! It’s the planet of the ants! My House I’m a harvester ant. We collect seeds. Under this mound is our nest. We built it all ourselves! There’s so many tunnels, it’s like a whole city. But we never get lost. How do we know what to build? I don’t know!…

a world of ants

Leafcutter ants These forest ants cut up leaves to take back to their nest. They chew the leaves into a paste, which they use to grow fungus. Then they eat the fungus. Weaver ants These ants use their babies to sew with! Weaver ants make nests out of leaves, held together with sticky silk spun by ant larvae. Adult ants will hold the larva up like a glue bottle to stick the sides of a leaf together. Trap-jaw ants Look at that huge jaw! These ants have the fastest bite in the world. They use it to catch tiny springtails. They can also snap their jaws to fling themselves in the air for a quick escape. Fire ants Sting! There are 280 different kinds of fire ants, and every one has a powerful sting. They use their…

the small secret of morse code

It was October 1837. Samuel Morse and I sat in our workshop, studying the many improvements that I, Alfred Vail, had made to Morse’s new telegraph machine. I had rebuilt the mechanism to make it much simpler, and now it was working pretty well. I’d first seen Morse’s device the month before, and I knew I had to be a part of this great project. The idea of messages speeding instantly through electric wires thrilled me. In those days, letters traveled as fast as a horse could carry them. But we were about to speed things up! Our machine was simple. It had a tappable switch that sent short blips of electricity through a wire. At the other end, the electric pulses pulled down a metal arm to make dots, dashes, and…

meet your mighty microbes

They may be too small to see—thousands could fit into the size of this dot . But they are all over you, inside and out. They outnumber the cells of your body by 10 to 1. You Are Habitat Most are bacteria. Some are fungi, like molds and yeasts. And some are viruses, so tiny and so simple that they lie on the boundary between living and not living. All of these tiny organisms are much, much smaller than your body’s own cells. Together, they make up what is called your microbiome, a complex web of life that lives in, on, and with you. Scientists are only just beginning to understand how it works. But one thing is clear: unlike the bad germs that can cause diseases, your microbiome works hard to…

virus or bacteria?

What Are Bacteria? Bacteria are tiny single-celled organisms. They live by eating tiny bits of sugar, oil, or other food. They help you digest a lot of what you eat. Most bacteria are harmless or helpful, but some cause diseases. Bacteria split to make more. You get sick when there are too many bad ones spitting out harmful wastes. Your body has a set of guard cells that looks out for bad bacteria and kills them. This is part of your immune system. Antibiotics are special medicines that poison bacteria. They can help fight stubborn bad bacteria. But they also kill good bacteria, so doctors try not to use them too much. What’s a Virus? Viruses are much smaller than bacteria. Scientists aren’t sure if they’re actually alive, or a kind of biological junk. A…
