Jenna Cook was born in China and abandoned on a street in the huge city of Wuhan in 1992 when she was just a baby.

Cook was adopted by a single American woman, a schoolteacher in Massachusetts, and later co-adopted by her godmother, who is her mother's partner.

Cook was accepted at Yale University, and at 20, she decided to go back to Wuhan in search of her birth mother.

Years ago, in a Brooklyn high school, a door slammed. Christopher Emdin, then a 10th-grader, immediately ducked under his desk. His math teacher accused him of being a clown and sent him to the principal's office.

Emdin wasn't being a clown.

Before cellphone cameras and Instagram, there was Polaroid. That funky-looking camera took hold as a social phenomenon nearly as quickly as the little, instant photographs they brought to life.

The Broadway musical that's set during a revolution may have set off a revolution of its own, too. Right now, Hamilton is the hardest ticket to get on Broadway. It's been called a once-in-a-generation experience. But it's safe to say the unconventional smash wasn't always a sure thing.

The Grammy-winning show portrays the life of Alexander Hamilton, a founder of the United States who was once a poor, orphaned boy "dropped in the middle of a forgotten spot of the Caribbean" — and it does so in the rhymes and music of hip-hop and pop.

Millions of Americans recharge their phones, screens and laptops before they go to bed at night, but do they recharge themselves?

Arianna Huffington, co-founder and editor in chief of The Huffington Post, says we are in the midst of a sleep-deprivation crisis that creates anxiety, as well as exhaustion, depression, a higher risk of motor vehicle accidents — and overall sleep-deprived stupidity. NPR's Scott Simon talked with her about her new book, The Sleep Revolution: Transforming Your Life, One Night at a Time.
