A Mammoth Mystery About 25,000 years ago, ancient humans built an enormous circle of mammoth bones—and no one knows why. The giant structur e is in Russia. Researchers started carefully digging it up in 2014. I t’s not the f irst ancient mammoth-bone ring they’v e found. But it is the oldest. It’s also quite large, at about 40 feet (12 m) across. The bones include at least 64 skulls, and other bones of do zens of mammoths. Ancient humans did hunt mammoths, but researchers don’t know f or sure whether these bones came from hunts, or from mammoths that died natur ally. They also don’t know what people used the structure for. It doesn’t look like anyone liv ed inside—ev en though it might hav e been the coolest (or creepiest) house…

the wheels of invention

1478 Winding Up The award for Earliest Known Drawing of a Working Car goes to the artist and inventor Leonardo da Vinci. He probably meant it to be a large wooden wind-up toy for a bored king, not a serious ride. It was only three feet long and had no seat. 1672 Steaming Ahead The first real motorized carts ran on steam power. Ferdinand Verbiest was a Dutch mathematician and astronomer working at the court of the emperor of China. He also liked to tinker with steam engines. He built what may have been the first working steam-powered car. Verbiest’s steam wagon could chug along at a fairly brisk pace, but when the water ran out, so did the ride. 1769 Crashing Forward In France, inventor Nicolas-Joseph Cugnot built a 5-ton tricycle that caused the…

speedy racers

Race cars are made to go fast—they zoom around the track at more than 200 miles (320 km) an hour. The people who design all these speedy cars have come up with lots of tricks to make them as fast and safe as possible. Some of their clever ideas end up in the cars we drive every day. There are many types of race cars. NASCAR and stock cars look like ordinary cars on the outside. Formula One and Indy Car racers look more like bugs, with narrow bodies and open-wheeled designs. But inside, all race cars are built for speed. So how do they go so fast? Under the Hood The most important part of a race car is the engine. The engine’s moving parts have to fit perfectly, so they don’t…

the car that drives itself

Honk! Honk! The bus! You run out the front door, then stop in your tracks. Where’s the big yellow bus? What’s that car doing here? The passenger door swings open all by itself. You look inside. Wait, where’s the driver? And the steering wheel? In fact, other than the seats, there’s nothing in this car . . . except a big silver button. Do you dare? You push it. The engine whirrs into action. The car slowly backs out of the driveway and cruises down the road. As you fasten your seatbelt, you feel like the coolest kid in the world. After all, you are only nine and you are driving yourself to school! Well, sort of. Cars Get Smart They might sound like science fiction, but cars that help with the driving are already on…

where am i? how gps works

The Global Positioning System, or GPS for short, is a network of about 30 satellites sitting above the Earth. Anywhere you go on Earth, there are several of these satellites somewhere above you. GPS satellites constantly send signals that just tell their name and the time (“Satellite A. 3:11”). To find out where you are, a GPS unit or cellphone reads the signals from three or four satellites and compares how long it took for each signal to arrive. The delay tells how far away you are from each satellite. Your phone compares the three distances and uses that to tell where you are. If you know you’re, say, 20,000 kilometers from satellite A, you must be somewhere on the red circle. If you’re 40,000 km from satellite B, you must be…

car gems

Look, what a colorful rock! Is it the remains of a prehistoric sea floor? You might think so. But don’t be fooled. These unusual rocks aren’t rock at all—they’re old car paint. Before the 1980s, car factories painted cars by spray-painting the metal car body, then baking it in an oven to harden. Paint drips would get baked onto the racks that carried the cars through the drying ovens. Auto workers would sometimes chip off the hard, swirly slag to take home for their kids. They jokingly called the lumps “fordite” (after Ford Motors) or “Detroit agate.” The layers in each chunk show the colors of cars being made at the factory it comes from. Modern cars don’t get painted and baked, so no more fordite is coming out of factories. But even though…
