Dear Dr. Universe: Why do some cheeses stink? – Cody, 11

When you take a whiff of stinky cheese, that smell is coming from one of its very important ingredients: microorganisms. Microorganisms are so small, you’d need a microscope to see them, but sometimes they give off a big stink. To find out more about stinky cheese, I talked to my friend Minto Michael. Michael is a professor of dairy science at Washington State University and told me microorganisms do a few different jobs to help make cheese. Read More ...

Dr. Universe: How do you make cider? -Julianna, 7

We can make cider with juice from apples. There are many different kinds of apples and a few different ways to squeeze out the juice. My friend Bri Valliere told me all about it.

Granny Smiths are more acidic and will make a tart cider. “We could make a single batch of one kind, or we could mix different kinds of apples together and see how it turns out,” she said. “No matter what, it’s going to taste good.” Read More ...

Dear Joe,

You’re not alone—cats don’t like broccoli much either. As a carnivore, I think a nice, meaty buffalo wing sounds great.

But humans are omnivores, meaning they eat both plants and meat. They’ve developed a taste for all kinds of things growing and living all over the world. So where do individual people’s preferences come from?

To find out, I visited Carolyn Ross, a professor of Food Science at Washington State University. Like you, she is very curious about why people like the foods they like.

Hi, Dr. Universe! When I was eating breakfast today, I came up with this question. Why does crispy rice make a popping sound when I pour milk over it? It makes me curious as a cat! -Allison, 11, Pullman, WA

Dear Allison,

My ears perked right up when I got your question. Like you, I’ve heard the sounds crispy rice cereal makes. But the truth is, I wasn’t entirely sure why it happens. There was only one way to find out.
