Hang on tight because the human brain keeps you on a 24-hour roller coaster.
Every day the human body produces a chemical messenger in the brain called melatonin. It tells the body when it is time to go to bed.
“It’s just like your parents,” said my friend Samantha Gizerian, an assistant professor at Washington State University, who studies how kid and baby brains develop. “Except you can’t run away from melatonin.”
Hi, there. I’m Dr. Universe. Wendy Sue Universe, that is.
Ever since I was a kitten, I’ve been digging in the dirt, gazing at the stars, exploring new places, and searching for answers to all kinds of questions about our world.
