Why are some dogs so small and some so large?
00:06:22 | May 14th, 2025
Dogs come in so many different sizes, from the tiniest teacup terrier to the giant Great Dane. How did we get such a delightful assortment of these furry best buddies? We asked Brains On producer and archaeologist Anna Goldfield to help us find the answer.
Why is the moon white and why does it have different shapes?
00:06:31 | May 12th, 2025
Some planets have lots of moons. Others have none. Earth has just one moon, but it’s a really great one. It can glow bright and white and sometimes it’s shaped like a big round ball. Other times it’s skinny like the white tip of a fingernail. Makes you wonder, why does the moon look the way it does? We asked Preston Dyches from NASA’s Jet Propulsion Laboratory to help us find the answer.
Did dinosaurs fart?
00:08:05 | May 9th, 2025
You fart. I fart. Your dog farts. We all fart! Or do we…? Birds don’t fart, and they’re the closest living descendants of the dinosaurs. So, did dinosaurs fart? We asked paleontologist Kallie Moore to help us find the answer.
What was the very first dinosaur?
00:06:56 | May 8th, 2025
Dinosaurs went extinct around 65 million years ago after an asteroid crashed into Earth. So we know when dinosaurs disappeared from the planet, but when did they appear? What was the first dinosaur, and how long ago did it live? We asked paleontologist Kallie Moore to help us find the answer.
How did Megalodon sharks go extinct?
00:07:49 | May 6th, 2025
Megalodon was the biggest shark species that ever lived. The biggest ones were almost 60 feet long, which is longer than a school bus! These gigantic sharks went extinct millions of years ago, but why? We asked paleontologist Kallie Moore to help us find the answer.
Did dinosaurs lay colorful eggs?
00:06:13 | May 5th, 2025
Dinosaurs were reptiles, which means they laid eggs! But what did these eggs look like? Were they big? Small? Speckly? Colorful? We asked paleontologist Kallie Moore to help us find the answer.
How does an immortal jellyfish go back to being a baby?
00:06:41 | May 2nd, 2025
Way out in the deep blue sea, there is a remarkable creature called the immortal jellyfish. This buoyant little blob can deal with being hurt or stressed by going from its adult form back to a baby!! Then it grows up all over again. Holy moly. How does that work? We asked science writer Christina Couch to tell us all about it.
Why are we more closely related to fungi than plants?
00:06:14 | April 30th, 2025
All living things on Earth are related. To help keep track of how close those relationships are, scientists organize life on Earth into groups using a system called taxonomy. Sometimes, taxonomy can be surprising – like, did you know that humans are more closely related to mushrooms and other fungi than we are to plants? How does that work? We asked microbiologist Christine Salomon to help us find the answer.
