Have you ever seen a magic trick where one thing changes to another thing? Well, that's nothing compared to what plants can do through a process called photosynthesis. In this episode, Sabrina talks about how photosynthesis works! This...

The Sahara is rather famously a desert, but it wasn't always that way. And during the time of lush green forests, there were plenty of people who lived there, but they've been hard to study. However, new genetic analysis has given us...

Many of the greatest biological dispersal events in history likely happened because animals inadvertently traveled across the oceans on floating debris.

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?

The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made...

Plants are finding their ways into caves, and it's all our fault.

Dinosaurs were huge—it's common knowledge. So why aren't modern mammals anywhere near that size? In this episode of SciShow, Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size...

Thanks to climate change, many regions are experiencing longer and more dangerous wildfire seasons. Here are 4 high-tech ways we are trying to stop these fires in there tracks, as well as one that’s a bit simpler.

What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail -- what he calls "a very high-tech accounting system" of carbon. In...

Plants are finding their ways into caves, and it's all our fault.

Emily Graslie of the Brain Scoop is back again with some more skulls to stump Hank, and Jessi from Animal Wonders brings in Blueberry the blue-tongued skink.

Cities have been working hard to transform the areas around roads into healthy habitats for important pollinating insects. And these insects seem to love our roadside landscapes, but these areas might also be luring them to their...

We've found thousands of exoplanets over the years, but if we're going to find one that can sustain life, we need to take a look at the one planet we know that can, Earth.

From gnocchi and salchipapas to potato chips and french fries, it seems like every cuisine around the world has embraced the potato! And this humble tuber did not originate in Ireland or France, but near Lake Titicaca near the border of...

Grizzly bears stick to a mostly vegetarian diet in sync with plant growing seasons. However, as grizzlies' habitats grow smaller, food is harder to come by. Using NASA satellites, scientists track the shifting, interrelated patterns of...

The pothos plant grows really well in a lot of places, so you’d think they’d be easy to coax blossoms out of, but even the greenest thumbs haven’t seen this plant bloom naturally in over 60 years! Why are the pothos petals so shy?

Farming erodes soil 50 times faster than it forms. We can change that, but will we?

Africa’s Sahara desert is a prime location, some say, to build arrays of solar panels and wind turbines. But scientists are aware that building these structures can potentially have large-scale effects on the surrounding environment that...

The Sahara was once home to hippos.

For millennia, humans have used plants for healing and protection, but myths have also depicted plants as conscious killers. Stories of poisonous plants, such as the deadly Javanese upas tree, have been sensationalized throughout...
