Dear Dr. Universe: I have a question for you about ants. From what I searched on Google, an ant has a nervous system, blood, open circular system, muscles, and a brain. So, Dr. Universe, the question is, do ants or other insects get headaches? Cause they work hard. –Joseph, 14, Singapore

Dear Joseph,

If you’ve ever had a headache, it might have felt like pain was radiating right out of your brain.

Hello Dr. Universe: I was wondering, how does an eclipse happen? - Susan, 13, San Francisco, CA

Dear Susan,

It just so happens the Great American Eclipse is coming up on Aug. 21, 2017. This solar eclipse will be the only one visible from across the lower 48 states in nearly a hundred years. When it happens, parts of the country will experience darkness for a couple minutes during the day.

Dear Dr. Universe: I would like to find out how ants are so strong. How is it possible that they can carry weight that is heavier than themselves? –Anita, 11

Dear Anita,

Ants are pretty good little weightlifters. My friend Rich Zack, a scientist at Washington State University who studies insects, knows a lot about ants. One kind of ant that he has studied can carry up to 20 times its own weight.

Why does meat get brown on the grill? – Christina, Seattle, Wash.

Dear Christina,

You know summer is just around the corner when the smell of barbecue is in the air. It’s a great question you ask and it leads us to the Meats Lab at Washington State University. That’s where I met up with my friend and animal scientist, Jan Busboom.

Hello! My name is Daiwik and my question is "Why are stars in space? Why are they needed? Can they be made on Earth?" No one I know knows the answer to this. Can you find out for me?- Thanks, Daiwik P.S. You're awesome!

Dear Daiwik,

If you are anything like me, you like watching the night sky. The stars we see are a lot like our nearest star, the sun. They are just much farther away. That makes stars look like small twinkly things instead of a big, furious thing like our sun.

Dear Dr. Universe: Do you know how human and animal interactions help our mind grow? Does it help us? Does it do nothing? This has fascinated me for a very long time. - Gabby G., 11, Berlin, VT

Dear Gabby,

Our brains are pretty busy. They are constantly thinking, feeling, and sensing our world. One thing that can help some people relax is spending time with an animal friend. You might play fetch with a dog, sit with a cat, brush a horse, or even watch a goldfish zip around its bowl.

People who spend a lot of time with animals might tell you that something special seems to be going on here. But scientists are looking for evidence and want to find out for certain just what is going on. They want to know … » More …

Why do scientists use Latin when they name organisms? – Arielle, New York

Dear Arielle,

Language changes all the time. Words get new meanings. New words get made up.

I talked about it with my friend Rich Zack. He’s an insect scientist at Washington State University. He does taxonomy. That’s the science of naming and classifying living things.

The way language changes is amazing—and skibidi. It’s neat that language morphs as we use it. But that can limit how well we understand each other. Some readers might see “skibidi” and think I passed out and hit random keys.

That’s the main reason scientists use Latin or ancient Greek to name things. They’re dead languages. Nobody uses … » More …

Will I ever like Brussels sprouts? - Susan 

Dear Susan,

Cats aren’t usually big veggie-eaters. But working with humans means that I get to taste all kinds of new delicacies—like Brussels sprouts.

I talked about food preferences with my friend Carolyn Ross. She’s a chemist and food scientist at Washington State University.

She told me that some people are extra sensitive to how foods taste. They’re called supertasters.

“Supertasters actually have more taste buds,” Ross said. “We’ve found that people who are supertasters are particularly sensitive to bitterness.”

Bitterness really strikes at a supertaster’s fungiform papillae. Those are the mushroom-shaped lumps on your tongue that house your taste buds. Because of … » More …

What was the largest dinosaur? – Carlos, California

Dear Carlos,

Your question almost stumped me. I don’t really have dinosaur scientist pals. So, I turned to an expert on finding answers.

My friend Emily Cukier is a science librarian at Washington State University. She helps students and scientists find information. I asked her what dinosaur is the largest—and how she figures that out.

Cukier told me that I should think hard about my question. Are we looking for the tallest dino? The longest? The heaviest? Those might be different answers.

Then it’s time to ask the internet.

“I’m a librarian, but the first thing I would do is put it into … » More …
