In 1964, a paleontologist named John Ostrom unearthed some fascinating fossils from the mudstone of Montana. Its discovery set the stage for what’s known today as the Dinosaur Renaissance, a total re-thinking of what we thought we knew...

A human with the metabolism of a hummingbird would need to eat about 80,000 calories a day to survive. That’s because staying warm by making your own heat takes a ton of energy. And that brings up a paradox, because creating your own...

The concept of warm-blooded and cold-blooded animals is outdated because there are actually tons of different animal thermoregulation strategies.

Sometimes, plants do unexpected things. Like control their own body temperature.

For a long time, scientists have debated whether dinosaurs were warm-blooded or cold-blooded. Turns out, they were probably somewhere in between.

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...

With winter in full swing, Jessi and Squeaks are snowed in for the day and passing the time with their favorite game: Guess That Animal!

For a long time, scientists have debated whether dinosaurs were warm-blooded or cold-blooded. Turns out, they were probably somewhere in between.

Here at SciShow we love digging into the subject of dinosaurs! Join Blake de Pastino, co-host and co-creator of the new series PBS Eons, as he takes you into the deep past for a few of our favorite dinosaur episodes!

You might have noticed that lots of drugs have special children’s formulas, and you might think that’s because smaller people need smaller doses. But you’d be wrong! Because kids aren’t just tiny adults.

Have you ever wondered how animals can live in super cold places all the time? Jessi shows you how some cool animals like whales, polar bears, and penguins, keep warm!

Hank takes us on a trip around the body - we follow the circulatory and respiratory systems as they deliver oxygen and remove carbon dioxide from cells, and help make it possible for our bodies to function.

Sometimes, plants do unexpected things. Like control their own body temperature.
