We spend about one-third of our lives sleeping, but much of that function remains a mystery. Weekend Edition Sunday is asking some pretty fundamental, yet complicated, questions about why we do it and why we can't seem to get more of it.
Dr. Matthew Walker says the question of why we sleep remains "that archetypal mystery."
Walker, the principal investigator at the sleep lab the University of California, Berkeley, works with patients who suffer from sleep abnormalities. He says the complexity of sleep makes the research that much more fascinating.
This is WEEKEND EDITION from NPR News. I'm Rachel Martin.
In the late 1980s and early '90s, success in the competitive world of late-night television sounded like this.

MARTIN: That, of course, was the signature shout out from "The Arsenio Hall Show." Arsenio interviewed everyone from Muhammad Ali to Madonna and, of course, there was that seminal pop culture moment when then-presidential candidate Bill Clinton played the sax on the Arsenio stage.
Gloria Estefan, the poster girl of the Latin music scene in the 1980s and '90s, the frontwoman for the Miami Sound Machine and the singer who made Middle America get up and conga...

GLORIA ESTEFAN: (Singing) Doctor, I've got this feeling inside of me, deep inside of me...come, shake your body, baby, do that conga. No, you can't control yourself any longer. Come on, shake your body, baby...the rhythm is gonna get you tonight.
On-air challenge:Each of the following answers is a made-up, two-word phrase in which the two words are homophones, and both words start with the letter C.
Last week's challengefrom listener Henry Hook of Brooklyn: Think of a well-known celebrity who goes by a single name — the last two letters of which are alphabetically separated by only one letter (like A and C, or B and D). Replace this pair of letters with the one that separates them, and you'll have a common, everyday word. What is it?
The effects of climate change often happen on a large scale, like drought or a rise in sea level. In the hills outside Missoula, Mont., wildlife biologists are looking at a change to something very small: the snowshoe hare.
Life as snowshoe hare is pretty stressful. For one, almost everything in the forest wants to eat you.
Alex Kumar, a graduate student at the University of Montana, lists the animals that are hungry for hares.
"Lynx, foxes, coyotes, raptors, birds of prey. Interestingly enough, young hares, their main predator is actually red squirrels."
Back in 1995, Cheryl Strayed hiked 1,100 miles of the Pacific Crest Trail along the West Coast of the United States. After the three-month journey, she came out on the other side stronger in every way: better able to cope with her divorce, her past drug abuse and her mother's death.
Strayed described the life-changing trek in her 2012 bestselling memoir Wild, and received countless emails from readers describing how connected they felt to her story. But there was one message that stood out in particular:
How far would you go for love? In Sara Farizan's debut novel, a studious 17-year-old girl named Sahar finds herself deeply, head-over-heels in love with her childhood best friend and neighbor — another teenage girl named Nasrin.
Their story takes place in Iran, where homosexuality is illegal, making their love that much more forbidden. When Nasrin is engaged to be married to a man, Sahar is crushed. In order to openly be with Nasrin, Sahar considers gender-reassignment surgery, which is more accepted in Iran than homosexuality.
