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 Newton, the forces are equal and opposite, keeping…

Scientists have developed a 3D-printed imitation of human skin with living cells, an advance they say could enable cosmetic testing without the…

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 materials that are essential for the green energy…

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 simple driving tracking app and some text message…

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 expert, believes his team has built a…

The Great Oxidation Event (GOE) some 2.4 billion years ago established the oxygen-rich atmosphere that many living things depend on today.

Curiously, when it came to evolving ways to actively use the element for respiration, some strains of bacteria had a head start.

Using a combination of…

According to the National Coffee Association, the average American drinks just over three cups of coffee a day. In moderation, coffee…

Scientists love to put things in categories. In the natural world, life is divided into several categories: animals, plants, fungi, protists (such as algae or amoebas), bacteria and archaea (microscopic single-celled organisms).

But recent research has suggested this list might not be…
