We've been exploring the mystery of sleep this morning - how we're not getting enough of it and why we need it in the first place.
(SOUNDBITE OF MUSIC)
MARTIN: We asked our listeners to share their sleep troubles.
EMILY MCMAMEE: So, I have always sleptwalked and slept-talked and it's always been amusing for everybody else around me. I learn about it the next morning when people tell me, you know, did you know that you just did this?
MARTIN: Emily McMamee is from Starksboro, Vermont.
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:
Measles was declared eliminated in the U.S. more than a decade ago. But in recent years, the highly infectious disease has cropped up in communities with low vaccination rates, most recently in North Texas.
There, 21 people — the majority of whom have not been immunized — have gotten the disease, which began at a vaccine-skeptical megachurch.
The outbreak began when a man who contracted the virus on a recent trip to Indonesia visited the Eagle Mountain International Church in Newark, about an hour and a half northwest of Dallas.
"J.D. Salinger spent 10 years writing The Catcher in the Rye and the rest of his life regretting it," according to a new book about one of America's best-known and most revered writers.
Salinger died three years ago at the age of 91, after publishing four slim books. But Catcher in the Rye has sold more than 65 million copies and has become a touchstone for young people coming of age around the world. It still sells hundreds of thousands of copies every year.
