Hey cool cats. I’m Dr. Universe. Whenever I go out and about, I make sure to wear my face mask. One way that germs enter the body is through the nose and mouth. The mouth and nose are interconnected. That’s why it’s so important that my face mask covers them both. I clean my hands before and after handling the mask and to avoid exposure to germs, I don’t want to touch the front of the mask. When I take off the mask, I use the loops or ties. When worn properly, this little piece of fabric can help make a big difference. We can all do our part to stay safe and healthy.
Hey cool cats, I’m Dr. Universe. When I come home from exploring, I always wash my hands. It takes about 20 seconds. I use soap and water. To keep track of time, I sing my ABCs. It’s important to wash the hands between the fingers and under the nails, anywhere germs might be hiding. I also wash up before making food, eating, using the bathroom, or touching my ears, nose, or mouth, places where germs can enter the body. With a little soap, water, and maybe even a song, we can all do our part to stay safe and healthy.
Hey cool cats, I’m Dr. Universe. When I run errands or explore the outdoors, I make sure to practice social distancing. That means keeping at least six feet of distance between me and others who do not live in my house. How wide is six feet? The length of a female lion, The wingspan of a bald eagle, or about three cats. It’s important to social distance because germs can spread from person-to-person. That’s why I like to give my neighbors plenty of space on the sidewalk and in the grocery store aisle. We can all do our part to stay safe and healthy.
Hey cool cats, I’m Dr. Universe, here to answer your baffling science questions like this one. How many suns are in the universe? The sun is actually a star, our nearest star, but there are lots of stars out there. Maybe you’ve tried counting them before. One, two, three, four, five, six, seven stars make up the big dipper. Astronomers estimate that the human eye could spot about 9,000 stars. Of course, the Earth blocks our vision so we only see about half of those in the night sky. If we use binoculars, we could see even more stars, about 200,000 of them. A small telescope can help us see more than 15 million stars and even more powerful telescopes can help us look for other galaxies which are home to even more stars. Have you ever been stargazing? What did you see in the night sky? Tell us about it sometime at Dr.Universe@wsu.edu.
Hey cool cats, I’m Dr. Universe. Here to answer your baffling science questions. Like this one. Dear Dr. Universe why are apples red? In nature different colors sometimes send a message to different plants and animals. The message might be don’t eat me as is the case of some brightly colored poisonous frogs. Other times it might be a chameleon using it’s colors to attract a mate saying hey look over here. But scientists think the apples red color might just be a way of telling hungry animals we’re delicious. Long before humans were shopping for apples at the supermarket bears were scavenging for fruit in forests. One idea is that bears are particularly attracted to red. A color that really pops against green leaves. When bears see the red fruit they eat it digest it and poop out the seeds. That way new generations of trees can grow and produce even more apples.

Hey cool cats, I’m Dr. Universe here to answer your baffling science questions. Like this one. Dear Dr. Universe, why do feet smell? We live in a world filled with all kinds of smells. Take off your tennis shoes after a long day and you might even get a whiff of something pretty stinky. You can blame it on your bacteria. Millions of these tiny things live on your feet. While bacteria are too small to see without a microscope, sometimes you can simply smell them doing their job. They like dark, damp warm places where they can eat dead skin and drink sweat. Inside your shoes and socks for example. There are more glands that produce sweat on your feet than on any other part of the human body. As bacteria eat there, they also turn your dead skin and sweat into chemical products that can really reek. It might just make you wanna plug your nose, but at least you’ll know the system that helps you smell, your olfactory system, is working well. Got a science question of your own?
