Dear Jarrett,
Animals can get through winter in all kinds of ways. Us cats like to curl up on a cozy couch. Some penguins huddle in groups to create heat. A lot of birds fly south to warmer weather. Perhaps you put on mittens and a coat.

Spiders can do some amazing things with their sticky, stretchy, and super-strong silk. Us cats are pretty curious about these little silk-spinning machines, too.

Whenever us cats go to the beach, we tend to keep a safe distance from the water and like to explore the shore. I once stumbled upon a big, beautiful pink and white seashell.

Pain is unpleasant, but we need it for survival. Just the other day I was out exploring when I stubbed my paw and let out a big meow. My nervous system was doing its job.

When I saw your question, I set out to explore with my bug net and a magnifying glass. I was searching all around for tiny insects when I ran into my friend Laura Lavine, a Washington State University scientist who studies bugs.
She said there are nearly a million different kinds of insects on Earth. The smallest of all the known ones are called fairyflies.

The other day, I wandered into a Washington State University greenhouse and ran into my friend Mechthild Tegeder, a professor and expert on plants.
She gently dug a small plant out of a pot so we could take a closer look. When she lifted it up, I pawed at the clumpy soil hanging from the bottom to reveal some stringy roots.

You might say the Kuiper Belt is the frozen frontier of our solar system. Out beyond Neptune’s chilly orbit, this saucer-shaped region is home to Pluto, billions of comets, and other icy worlds.
“The Kuiper Belt is really the edge of knowledge,” said my friend and astronomy professor Guy Worthey when we met up in the Washington State University planetarium.
“Out there it’s a little dim,” Worthey said. “We are pretty far from the Sun.”
In fact, it’s about 3 billion miles away. Even at the speed of a jet airplane, it would take more than 680 years to travel from Earth … » More …

You know, your question reminds me of a couple other science questions from curious readers. Evangeline, age 7, wants to know why her hair is black. Sureya, age 8, wants to know why some people have curly hair.
It just so happens that one of my favorite science projects explores our questions about what makes us unique. It has to do with our DNA, or the blueprint for life.

We calculated Pi with some of my favorite items: yarn and a tuna can. You can try it at home, too.

A couple months before you were born, your skeleton was soft and bendy. It was made out of cartilage, the same material that’s in your nose and ears now. But when certain cells in your body called osteoblasts and osteoclasts began to work together, new bone started to form.

We cats have a reputation for being lazy. We sleep a lot. But the truth is when I got your question, I didn’t know much about laziness. So, I decided to talk about it with a couple of psychologists here at Washington State University.

There’s something about a chameleon’s darting eyes, long tongue, curled tail, and ability to climb that makes it a fascinating animal to watch. Especially when it’s changing colors.
And the latest research on your question suggests that how a chameleon changes has more to do with light than scientists once thought.

When bees make hexagons in their hives, the six-sided shapes fit together perfectly. In fact, we’ve actually never seen bees make any other shape. That’s what I found out when I visited my friend Sue Cobey, a bee researcher at Washington State University.
Cobey showed me some honeycombs where the female bees live and work. Hexagons are useful shapes. They can hold the queen bee’s eggs and store the pollen and honey the worker bees bring to the hive.
When you think about it, making circles wouldn’t work too well. It would leave gaps in the honeycomb. The worker bees could use triangles or squares for storage. Those wouldn’t leave gaps. But the hexagon is the strongest, most useful shape.

Well, we don’t know for certain. Looking up to the stars at night, I’ve often wondered if alien cats are out chasing alien mice or taking naps on other planets.
My imagination aside, your questions are like those scientists are asking, too. And it’s no wonder we are so curious.
With billions of planets in our galaxy, including small Earth-like worlds, the possibility of life out there is an exciting thought to many people. So, humans have set out to look for planets that might support life.

My friend Kate Evans said the answer really depends on whether you want the perspective of a person, a plant, or even a cat. Evans is a plant scientist at Washington State University in Wenatchee, where she investigates fruit in the Apple Capital of the World.

For some trees, the key to survival is growing sweet, ripe fruit.
