Nicotine addiction came with high price for one teen, and he’s not alone. Increasingly popular vape devices like JUUL pose health risks and harm developing brains.

Wally “Wallace” Broecker, a pioneer of climate science, explains why he wishes he could have lived another 50 years.

After Ethiopian flight 302 fell from the sky, marking the second Boeing 737 Max 8 crash within 6 months, experts weigh in on what may have happened.

Discover the science behind the phenomenon.

The World Wide Web revolutionized the way we use the internet. Before it existed, the internet was mostly used by scientists and engineers to share information.

By identifying and studying super corals—those that survive best in warming waters—scientists are trying to help reefs across the planet.

Warming air and sea surface temperatures are making storms wetter and more intense.

It changes the dynamic of the entire reefscape, and can be detrimental to corals and the animals that depend on them.

Samples of carbon dioxide from Mt. Vesuvius can reveal how close magma is to the volcano's surface. To collect them, researchers descend into Vesuvius' 1,000-foot-deep crater.

In the shadow of Italy’s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. If it erupts, millions of lives could be at risk. Scientists explore its unique geology and develop a warning system that could prevent Naples becoming the next Pompeii.

Returning a rocket safely back to the launch site involves a series of complex steps which begin on the edge of space, when still traveling at over 3,500 miles per hour.

New technologies are making rockets cheaper and more powerful than ever before. As companies like SpaceX and Virgin Galactic make space more accessible, and NASA returns to crewed spaceflight, a new era of space exploration may be on the horizon.

In the first images released of Ultima Thule, the object looked like two spheres — kind of like a snowman. The latest photo shows a very different perspective.

Kicking a field goal seems pretty straightforward: you just kick the ball as hard as you can between the goal posts at the back of the end zone. But if it were that easy, then kickers would almost never miss. Join physicist Tim Gay and semi-pro football kicker Hermes Lima as they explain all the factors that go into kicking a successful field goal.

Stunning new archaeological evidence provides clues about the Egyptians who built the Great Pyramid of Giza--and how they did it. Join researchers as they delve into the logbook of a work crew and discover how the massive project transformed Egypt.
