In 2021, a crew of civilian astronauts spent three days in Earth orbit. While they were up there, they performed a bevy of experiments. And not only did we learn more about what space travel can do to the human body, we also learned...

The Grand Canyon is super-wide and super-deep, which might make you think that the Colorado River, which carved it, is particularly old or powerful. Or at least that's what I thought.

Humans eat a lot of different animals, but almost none of them are carnivores - why?

The Order of Operations is Wrong

A mathematician with a knife and ball begins slicing and distributing the ball into an infinite number of boxes. She then recombines the parts into five precise sections. Moving and rotating these sections around, she recombines them to...

After years of brand building, marketing veteran Sylvester Chauke realized that his industry had sold the world on overconsumption, with devastating consequences. He shares how marketers could instead promote sustainability with "honest...

Driven by the belief that businesses can — and should — invest in the communities around them, Intercorp founder and philanthropist Carlos Rodríguez-Pastor has built schools, pharmacies and a literal bridge to better serve Peru's growing...

Being infected with a parasite is bad, right? So why are wolves in Yellowstone National Park infected with Toxoplasma gondii some of the most successful individuals<br/>

In standard use, the S-matrix can be calculated if you understand the forces in the interaction region - for example, in the nucleus of an atom. But what if you don’t know those internal interaction forces? Heisenberg sought a way to...

Every time you walk out the door, light from the Big Bang strikes your face, enters your eyes. This is the cosmic microwave background radiation - the left-over heat-glow from the very early universe. We can’t see this microwave light...

It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well we’ve just taken that to the next level with a galaxy-spanning gravitational wave detector that may have detected a foundational element of...

The search for a single number: the hubble constant, which is the rate of expansion of our universe, has consumed astronomers for generations. Finally, two powerful and independent methods have refined its measurement to unprecedented...

In the quest to understand how evolution basically built the woolly mammoth, we may have found the blueprints for building them ourselves.

Charles Darwin encountered a tiny fox-like creature during his famous voyage but instead of discovering its fascinating evolutionary story, he just knocked it on the head with his geology hammer.

What’s the real story of the dodo? How did such a unique bird even evolve in the first place? And are we really responsible for its extinction?

Quantum computing is cool, but you know what would be extra awesome - a quantum internet. In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.

You're peering into the Amazon River when, suddenly, you lose your footing and fall. Piranhas dart about in the rapidly approaching water. So, are you doomed? Will your fall trigger a feeding frenzy that will skeletonize your body within...

You probably have a bag of frozen corn in your freezer, or have chowed down on a buttery ear of corn at a cookout. But not only did it take thousands of years for humans to domesticate teosinte to corral it into what we now know as corn,...

We used to think neural circuits were rigid and robotic, but now we know that's not true -- thanks to crab stomachs.

Despite being a noble gas, helium has a carbon footprint. We haven't managed to find any helium reservoirs that don't also contain natural gas. But must they? Scientists and startups alike are on the hunt.

Nuclear war is a terrifying existential threat, but we shouldn't only fear the blasts because the ensuing smoke is the real killer.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Time Magazine has called it "the most horrible drug in the world," and last month, it hit the US. Because seriously, why would you take a drug that rots your flesh, bones, and brain?! Hank Green discusses the science behind the street...
