Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent...

Dinosaur mating behavior has been the subject of a lot of speculation, but what can we actually say about it from the fossil record?

The Toba supervolcano was the biggest explosive eruption of the last 2.5 million years. And humans were around to see it, or at least feel its effects! But what were those effects?

While Earth’s natural history has been playing out over the last few billion years, another epic planetary saga has also been unfolding right next door.

These relatives of ours lived in Eurasia for more than 300,000 years. They were expert toolmakers, using materials like stone, wood, and animal bone. They were also skilled hunters and foragers, and may even have created cave art. So...

Maybe it’s a little self-centered that we can be pretty focused on the DNA that we got from Neanderthals – but we shouldn’t forget that gene flow goes both ways.

We can track our history of eating just about anything back through the fossil record and see the impact it’s had on our evolution. Throughout time, part of the secret to our success as a species has been our early - and sometimes fatal...

Our DNA holds evidence of a huge, ancient pandemic, one that touched many different species, spanned the globe, and lasted for more than 15 million years.

Throughout the first half of the 20th century, Neandertals were thought to have been…primitive. Unintelligent, hunched-over cavemen, for lack of a better word. But the discoveries made in that Iraqi cave provided some of the earliest...

If we can see ourselves in the way our ancient cousins dealt with death…what else could we have in common?

Paleontologists found a small theropod dinosaur skull right on top of a nest of eggs that were believed to belong to a plant-eating dinosaur. Instead of being the nest robbers that they were originally thought to be, raptors like this...

It may be that for every star in the universe there are billions of microscopic black holes streaming through the solar system, the planet, even our bodies every second. Sounds horrible - but hey, at least we’d have explained dark matter.

For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

Some of us can't get enough of that new car smell. But certain volatile organic compounds (VOCs) that help create this aroma are linked to cancer. While this doesn't mean new car smell definitely increases your chance of getting cancer,...

Once upon a time, we coexisted with other human species. And there’s one place on Earth that may have taught us more about that than any other single site.

Did you know that a massive ancient flood triggered a thousand year ice age? 13,000 years ago, North America seemed to be thawing from a 2.6 million-year ice age. Then, a huge swath of Earth was suddenly plunged back into the cold for...

For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...

Scientists who piece together our past can do so through the rare fossil or artifact, or they can go to one convenient location: a hyrax latrine.

Your dog might seem like a bit of a goof, but they might be capable of more tricks than you think. A new study from researchers in Hungary investigated whether dogs can distinguish between new and familiar languages.

There are still some great mysteries of our universe that physicists can't explain. How is that possible? Join us as we break down the 4 greatest mysteries of physics in this episode of SciShow hosted by Michael Aranda!

Despite some bold claims, most supplements can’t really "boost" your metabolism, and the actual changes we can make to it are pretty limited.

In your brain the right side controls the left half of your body and vice versa. We still aren't sure why this is, but some scientists have come up with a pretty bizarre explanation: that some ancient vertebrate ancestor was born with...

We know modern day healthcare to be a world of expensive premiums, long wait times and frustrating hospital bills. However health care has existed long before insurance premiums and online portals! Curious about when healthcare for...

Bees aren’t the only pollinators out there. Some of the other, more surprising pollinators aren't just unconventional, they give us unique examples of how the relationship between pollinators and plants evolved in the first place. Hosted...
