If you’re a fan of avocados, you might have heard that they only exist thanks to prehistoric creatures called giant ground sloths. In fact, you’ve probably heard that from us. But as it turns out, the real story is way more complicated -...

Have you ever seen cat pheromones, sometimes branded as Feliway, that promise to address problem behaviors like cat scratching, fighting, and stress? These products are based on real science. But do they work?

From an Australian fire that's been continually burning for millennia, to earthquakes that shake the ground for centuries, here are four natural disasters that lasted way longer than you might have expected.

Almost everything we know about the reproductive practices of European eels comes from a genius study conducted more than 100 years ago.

As humans live longer than ever before, we need our implants to last as long as we do, says bioengineer Nina Tandon. Using stem cells and digital fabrication, she's working on growing anatomically precise spare parts for the human body,...

Animals eating other animals seems like a tale as old as time, but it's only almost that old. Predation had to evolve in the Ediacaran period -- so let's look at early almost-predators like Auroralumina, Kimberella, Ikaria, and whatever...

While there's still a lot that astrophysicists don't know about the Big Bang, there are some things we do know. So today, let's get caught up on the Big Bang basics.

Mars’s moon, Phobos, is striped with grooves all across its surface. But if one theory about where they came from is true, does that mean this moon might be on its way out?

Earth didn't always have the land beneath your feet, but what might have caused it to form is a bit of a mystery.

A majority of modern astronauts experience any one of a suite of symptoms scientists collectively call Space Motion Sickness, or SMS. But despite knowing about it for nearly as long as humans have gone into space, we still don't know...

Mountain ranges usually don't form in the middle of continents. Except for the Rocky Mountains. We'll go into the baffling Laramide Orogeny and a few possible reasons why the Rockies might be in the wrong place.

The pain reliever known as acetaminophen or paracetamol, marketed under brand names like Tylenol, Calpol or Panadol, has an excellent reputation. But the quality of evidence that it actually works is shockingly poor. So, do doctors and...

While clubs are practically synonymous with ankylosaurs, we’ve only started to get to the bottom of how they worked and how this unusual anatomy developed in the first place.

Do our modern horses descend from just one domesticated population, or did it happen many times, in many places? Answering these questions has been tricky, as we’ve needed to bring together evidence from art, archaeology, and ancient...

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...

Otherwise landed in 2004 with its twin - MER-A, better known as Spirit. These six-wheeled golf-cart-sized robots were Swiss army knives of geological lab instruments. Opportunities most spectacular discovery where these cute little...

Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between...

The ability to make and use fire has fundamentally changed the arc of our evolution. The bodies we have today were, in many ways, shaped by that time when we first tamed fire.

We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

For decades, scientists believed dinosaurs were diurnal and tiny mammals were nocturnal. But as researchers have uncovered more mammalian fossils and studied the biology of different dinosaur species, they’ve found some surprising results.

There was a time in Earth’s history that was so stable, geologists once called it the Boring Billion. But the fact is, this period was anything but boring. In fact, it set the stage for our modern version of plate tectonics - and...

Paleontologists have been studying nodosaurs since the 1830s, but nobody had ever found a specimen like Borealopelta before. The key to its exceptional preservation was where it ended up after it died and how it got there.

A mysterious, large feline roamed Eurasia during the last ice age. Its fossils have been found across the continent, and it’s been the subject of ancient artwork. So what exactly were these big cats?

A new discovery raises an important question: from an evolutionary perspective, who really has the stranger wings?
