Dolphins are super cool sea creatures that can swim fast, jump high, and make all kinds of nifty noises. But did you know that they also have big complicated brains like humans do? How did they get those big brains, and what do they use them for? We asked science writer Vicky Stein to help us find the answer.Got a question that’s FIN-tastic? Send it to us at BrainsOn.org/contact, and we’ll set out with a great sense of porpoise to find the answer!

Do we sneeze in our sleep?
Being asleep is kind of a funny thing, because you don’t know if you’re doing anything in your sleep – because you’re asleep! Some people talk in their sleep, others get out of bed and walk around… but do we ever sneeze in our sleep? We asked neurologist Michael Hall if it was even possible. Got a Moment of Um question that’s keeping you awake? Send it to us at BrainsOn.org/contact and you could hear the answer on a future episode!

Do lizards smell with their tongues?
The sense of smell is so powerful. Without it, we couldn’t sniff out freshly-baked muffins, stinky garbage, or smoky campfires. Some animals use their noses, others use antennae or even their feet to smell. But what about lizards? They have nostrils, but do they use them to smell? We asked lizard researcher Laura Kojima to help us answer this question. Got a question that you need to make scents of? Send it to us at BrainsOn.org/contact, and we’ll help you sniff it out.

Do we have our own gravity?
You might have heard of gravity as the force that keeps us firmly on the ground and not floating off the planet. Big things (like planets, moons, and stars) have gravity that pulls other objects toward them. But what about smaller things? Like… us? Do we have our own gravity? If there’s a question pulling at you like a powerful force, we can help with that! Submit your Moment of Um question at BrainsOn.org/contact and we’ll find the answer.

Why do beans give us gas?
Beans are delicious. From edamame to lentils, there’s a bean for everyone! But they can also make us a little tooty. Why is that? We asked pediatrician Wendy Hunter to help us find the answer.Got a question that’s a real gas? Send it to us at BrainsOn.org/contact and we’ll rip a good one (answer, that is)!
Moment of Um is your daily answer to those questions that pop up out of nowhere and make you go… ummmmmmm. Brought to you by your friends at Brains On at APM Studios.
