All astronomical objects are formed by gravity pulling matter together.

If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, this spin rate will only become greatly enhanced as the object…

An expedition to the bottom of the Great Blue Hole off the coast of Belize in Central America has returned with a cargo of worrying information.

After studying a 30-meter (98-foot) sediment core extracted from the floor of the sinkhole,…

Romeo and Juliet were a pair of doomed, star-crossed lovers. Now, astronomers have detected a pair of doomed star-crossed stars. Like Shakespeare’s famously unlucky couple, two white dwarfs spiraling around each other are on a course toward…

If the ball hits the stick and bounces back, what will happen to the stick? If you said the stick will recoil to the right, you’re correct. We can think of this as a collision. When two objects collide, they exert forces on each other. And per…

Scientists have developed a 3D-printed imitation of human skin with living cells, an advance…

Kazakhstan discovered its largest deposit of rare earth metals, containing around one million tonnes of the elements that are seen as vital for the future economy, the Central Asian country said Wednesday.

Rare earths comprise 17 raw…

A new study from AAA confirms something that most of us already know: when drivers know their behavior is being monitored, they tend to drive more safely. But here’s the twist—no one in this study was being punished or rewarded. A…

For decades, scientists have dismissed the idea of reactionless propulsion—the concept of generating thrust without expelling propellant—as a fantasy that defies the laws of physics. But Charles Buhler, a former NASA electrostatics…

The U.S. now hosts over 157,000 wind turbines. If each tower holds three blades, and each blade’s weight is about 65 glass fiber-reinforced polymer (GFRP), that’s a lot of plastic. Even if each turbine lasts an estimated 30 or so years, those…

Along with a slew of other physical impacts that running a marathon can have on the human body, a new study reveals that your body may also start eating your brain while running the 26.2-mile race. 

While this sounds terrifying, the effects the…
