– Daniel, 8
Dear Daniel,
It sure sounds like a nice idea. Print a bunch of money and everyone gets rich. We could buy anything we wanted. Ah, if only it were that easy. It turns out printing more money would have a much different outcome than we might like to imagine. » More …

-Keegun, 8th grade, E. Wash.
Dear Keegun,

Dear Dr. Universe: Why do we find some things scary? -Jack H., 8, UK

Dear Aaryan,
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.
My first stop was the Psychology of Physical Activity Lab. That’s where I met up with my friend, Professor Anne E. Cox. » More …
